How to Check Fluids on Tesla cars

Removing the Maintenance Panel

To check fluid levels, remove the maintenance panel:

  1. Open the front hood.
  2. Pull the maintenance panel upward to release the clips that hold it in place.
  3. If checking the Battery coolant, remove the cabin intake trim panel by pulling it upwards to release the clips that hold it in place.

CAUTION: The maintenance panel protects the front trunk from water. When re-attaching, make sure it is fully seated.

Checking Battery Coolant

Your Battery coolant should not need to be replaced for the life of your vehicle under most circumstances. However, if the quantity of fluid in the cooling system drops below the recommended level, the touchscreen displays a warning message. Stop driving Model 3 as soon as safety permits and contact Tesla.

Fluid Level Check

DO NOT REMOVE THE FILLER CAP AND DO NOT ADD FLUID. Doing so can result in damage not covered by the warranty.

Do Not Top Up Battery Coolant

WARNING: Battery coolant can be hazardous and can irritate eyes and skin. Under no circumstances should you remove the filler cap and/or add coolant. If the touchscreen warns you that the fluid level is low, contact Tesla immediately.

To maximize the performance and life of the Battery, the cooling system uses a specific mixture of G-48 ethyleneglycol coolant (HOAT). Contact Tesla for more specific information about the coolant.

Checking Brake Fluid

WARNING: Contact Tesla immediately if you notice increased movement of the brake pedal or a significant loss of brake fluid. Driving under these conditions can result in extended stopping distances or complete brake failure.

A red brake indicator ((!)) on the touchscreen alerts you if the quantity of fluid in the brake reservoir drops below the recommended level. If it displays while driving, stop as soon as safety permits by gently applying the brakes. Do not continue driving. Contact Tesla immediately.

Topping Up the Brake Fluid

Do not top up your brake fluid. The following instructions are provided for information purposes and future reference only:

  1. Clean the filler cap before removing it to prevent dirt from entering the reservoir.
  2. Unscrew the cap and remove it.
  3. Top up the reservoir to the MAX mark using the appropriate brake fluid.
  4. Replace the filler cap, ensuring it is fully secured.

    WARNING: Only use new fluid from a sealed airtight container. Never use previously used fluid or fluid from a previously opened container—fluid absorbs moisture which decreases braking performance.

    WARNING: Brake fluid is highly toxic. Keep containers sealed and out of the reach of children. In the event of accidental consumption, seek medical attention immediately.

    CAUTION: Brake fluid damages painted surfaces. Immediately soak up any spills with an absorbent cloth and wash the area with a mixture of car shampoo and water.

Topping Up Windshield Washer Fluid

The only reservoir into which you can add fluid is the windshield washer fluid reservoir, which is located behind the front trunk. When the level is low, a message displays on the touchscreen.

To top up the washer fluid:

  1. Open the hood.
  2. Clean around the filler cap before opening it to prevent dirt from entering the reservoir.
  3. Open the filler cap.
  4. While avoiding spilling, fill the reservoir until the fluid level is visible just below the filler neck. The reservoir has a capacity of 3.2 liters.
  5. Wipe up any spills immediately and wash the affected area with water.
  6. Replace the filler cap.

NOTE: Some national or local regulations restrict the use of Volatile Organic Compounds (VOCs). VOCs are commonly used as antifreeze in washer fluid. Use a washer fluid with limited VOC content only if it provides adequate freeze resistance for all climates in which you drive Model 3.

CAUTION: Do not add formulated washer fluids that contain water repellent or bug wash. These fluids can cause streaking, smearing, and squeaking or other noises.

WARNING: In temperatures below 40° F (4° C), use a washer fluid with antifreeze. In cold weather, using a washer fluid without antifreeze can impair visibility through the windshield.

WARNING: Windshield washer fluid can irritate eyes and skin. Read and observe the instructions provided by the washer fluid manufacturer

How to Replace and Maintain Wiper Blades

Replacing Wiper Blades

For optimum performance, replace the wiper blades at least once a year.

NOTE: Only install replacement blades that are identical to the original blades. Using inappropriate blades can damage the wiper system and windshield.

To replace the wiper blades:

  1. Shift into Park and turn off the wipers.
  2. Touch Controls > Service > Wiper Service Mode > ON to move the wipers to the service position.
  3. Lift the wiper arm a short distance away from the windshield, just far enough to access the wiper blade.
    CAUTION: Wiper blades do not lock into a lifted position. Do not lift a wiper arm beyond its intended position.
  4. Place a towel between the wiper arm and windshield to avoid scratching or cracking the windshield.
  5. Hold the wiper arm and press the locking tab while sliding the blade down the arm.
  6. Align the new wiper blade on the wiper arm and slide it toward the end of the wiper arm until it locks into place.
  7. Turn Wiper Service Mode off to return the wipers to their normal position.

Checking and Cleaning Wiper Blades

Periodically clean the edge of the wiper blades and check the rubber for cracks, splits, and roughness. If damaged, replace the blade immediately to prevent damage to the glass and improve visibility.

Contaminants on the windshield, or on the wiper blades, can reduce the effectiveness of the wipers. Contaminants include ice, wax spray from car washes, washer fluid with bug and/or water repellent, bird droppings, tree sap, and other organic substances.

Follow these guidelines for cleaning:

• Clean the windshield and wiper blades using washer fluid, isopropyl (rubbing) alcohol, or non-abrasive glass cleaner approved for use on automotive glass and rubber. Inappropriate products can cause damage or smears, and create glare on the windshield.

• Lift the wiper arm a short distance away from the windshield, just far enough to access the wiper blade. Do not lift a wiper arm beyond its intended position.

If the wipers remain ineffective after cleaning, replace the wiper blades.

Cleaning Washer Jets

If a windshield washer becomes blocked, use a thin strand of wire to clear any blockages from the nozzles.

WARNING: Do not operate the washers while cleaning Model 3. Windshield washer fluid can irritate eyes and skin. Read and observe the washer fluid manufacturer’s instructions.

How Tesla Autopilot works

How it Works
Drivers engage Traffic Aware Cruise Control and Autopilot in Model S and Model X by using the cruise control stalk on the left of the steering column; in Model 3, drivers use the gear selector stalk on the right of the steering column for those functions. A single pull on the stalk engages Traffic-Aware Cruise Control, and two successive pulls engages Autosteer. A grey steering wheel icon appears on the car’s display, next to the speedometer, when the system is available to engage. The icon appears highlighted in blue once the driver engages Autosteer. The system is intended for highway use.

Before enabling Autopilot, the driver first needs to agree to “keep your hands on the steering wheel at all times” and to always “maintain control and responsibility for your vehicle”. Subsequently, every time the driver engages Autopilot, they are shown a visual reminder to “keep your hands on the wheel”. Tesla’s advanced features like Autosteer, Navigate on Autopilot and Summon are disabled by default. Tesla does this to ensure that those using the feature do so knowingly and deliberately. To enable them, customers must go to the Autopilot Controls menu within the Settings tab and turn them on.

When Autopilot is in use, it measures the amount of torque that the driver applies to the steering wheel and, if insufficient torque is applied, an escalating series of audible and visual alerts again reminds the driver to place their hands on the wheel. Since the steering wheel rotates as it normally would when driving, the driver’s hands must move with the wheel. This helps ensure the driver is attentive, and that the steering wheel is properly oriented in the event the driver needs to take over. The system’s hands-on reminders and alerts are delivered based on each unique driving scenario, depending on numerous factors including speed, acceleration, road conditions, presence of other vehicles, obstacles detected, lane geometry, and other sensor inputs. If the driver repeatedly ignores those warnings, they will be locked out from using Autopilot during that trip.
This is designed to prevent driver misuse and is among the strongest driver-misuse safeguards of any kind on the road today. Additionally, if a driver tries to engage Autopilot when it is not available, they will be prevented from doing so. If a driver wants to initiate an automated lane change while Autopilot is use, they can simply engage the turn signal in the direction that they would like to move. The car will then wait for an opening to change lanes, and during that time drivers should still double check their blind spots and mirrors.

Navigate on Autopilot
To use Navigate on Autopilot, a driver must first enable the feature in the Autopilot Controls menu within the Settings tab, and then enter a destination into the navigation system. Navigate on Autopilot must be enabled for each unique trip via the Navigate on Autopilot button on the map’s turn-by-turn driving directions. If Navigate on Autopilot is not available for a drive, the button will not appear on the turn-by-turn direction list. Once Navigate on Autopilot is in use, the 360-degree visualization on the center display shows a single blue line indicating the path of travel. There are two types of lane changes while Navigate on Autopilot is in use: route-based lane changes which are designed to keep you on your navigation route, and speed-based lane changes, which are designed to keep your vehicle moving as close to your set speed as possible.

Navigate on Autopilot can be customized to a driver’s preferences with four different settings:

Enable at Start of Every Trip
Navigate on Autopilot can be set to automatically turn on each time a driver enters a navigation route. Once enabled, anytime a driver is on a highway and uses Autopilot with a location plugged into the navigation bar, the feature will be on by default.

Speed-Based Changes
There are four available settings for speed-based lane changes (Disabled, Mild, Average, or Mad Max). When enabled, Navigate on Autopilot’s speed-based lane changes will suggest transitions into adjacent lanes that are moving faster, in the event that your vehicle is traveling slower than the set cruise speed (for instance, if you approach a slow-moving car or truck ahead). The Mild setting suggests lane changes when you’re traveling significantly slower than your set speed, whereas Mad Max will suggest lane changes when traveling just below your set speed.

Require Lane Change Confirmation
If a driver selects ‘No’ to Require Lane Change Confirmation, lane changes will happen automatically, without requiring a driver to confirm them with the indicator stalk first. Drivers can choose how they wish to be notified about lane changes, giving them enough time to check their surroundings and determine whether they want to cancel the lane change before it’s made. Automatic lane changes can be cancelled by moving the car’s turn signal or by pressing the lane change cancellation pop-up notification on the car’s touchscreen. This feature does not make a car autonomous, and lane changes will only be made when a driver’s hands are detected on the wheel.

Lane Change Notification
Drivers can elect to get notified about an upcoming lane change by receiving an audible chime as well as a default visual prompt. Additionally, all cars made after August 2017 also have the option to have their steering wheel vibrate for the alert as well. Each of these notifications are meant to provide drivers with the opportunity to check their surroundings and determine whether they want to cancel the lane change before it’s made.

Other Autopilot Features
To use Autopark, a car must be driving at a very low speed on a street, and a “P” will appear on the Instrument Panel when a Tesla detects a parking spot. Then, a driver must put the car in reverse and press start, and Autopark will begin to maneuver the vehicle into the parking space by controlling the vehicle speed, gear changes and steering angle.

The driver can override any of Autopilot’s features at any time by steering, applying the brakes, or using the cruise control stalk (Model S and Model X) or gear selector stalk (Model 3) to deactivate.

To use Summon, a driver must open the Tesla app, press Summon, and then press the forward or reverse buttons. Model S and Model X owners can use Summon with their key fob by holding the center of the key fob for three seconds until the car’s hazard lights come on, and then pressing either the frunk or trunk button on the key fob to Summon forwards and backwards respectively.

Hardware + Software
Autopilot’s robust sensor and camera suite provides drivers with an awareness of their surroundings that a driver alone would not otherwise have. Cars built between September 2014 and October 2016 include one camera, a less-powerful radar, and ultrasonic sensors. All Tesla vehicles built since October 2016 include eight external cameras that feed Tesla-developed neural net, 12 ultrasonic sensors for detecting nearby obstacles, a forward-facing radar that senses through fog, dust, rain, snow, and under cars, and a powerful onboard computer that process these inputs in a matter of milliseconds.

Because every Tesla is connected, Tesla cars are able to get better over time with software updates and the introduction of new features through over-the-air updates. This is even more true with Autopilot as Tesla continuously works to make the system even more capable and keep our customers at the forefront of technology. Tesla’s FSD computer is currently in production and will enable full-self driving via future over-the-air software updates.

Autopilot is an advanced driver assistance system that is classified as a Level 2 automated system according to SAE J3016, which is endorsed by the National Highway Traffic Safety Administration. This means Autopilot also helps with driver supervision. One of Tesla’s main motivations for Autopilot is to help increase road safety, and it’s this philosophy that drives their development, validation, and rollout decisions.

Autopilot is intended for use only with a fully attentive driver who has their hands on the wheel and is prepared to take over at any time. While Autopilot is designed to become more capable over time, in its current form, it is not a self-driving system, it does not turn a Tesla into an autonomous vehicle, and it does not allow the driver to abdicate responsibility. When used properly, Autopilot reduces a driver’s overall workload, and the redundancy of eight external cameras, radar and 12 ultrasonic sensors provides an additional layer of safety that two eyes alone would not have.

Active safety features come standard on all Tesla vehicles made after September 2014 for an added layer of safety beyond the physical structure of each car, and are made possible by our Autopilot hardware and software system, even for customers who have not purchased Autopilot.
