How Traction Control system works on Model 3

How It Works

The traction control system constantly monitors the
speed of the front and rear wheels. If Model 3
experiences a loss of traction, the system minimizes
wheel spin by controlling brake pressure and motor
power. By default, the traction control system is on.
Under normal conditions, it should remain on to ensure
maximum safety

The yellow indicator (image of the car on a slippery road)
flashes on the touchscreen whenever the traction
control system is actively controlling brake pressure
and motor power to minimize wheel spin. If the indicator
stays on, a fault is detected with the traction control
system. Contact Tesla Service.

WARNING: Traction control cannot prevent
collisions caused by driving dangerously or
turning too sharply at high speeds.

Allowing Wheel Slip

To allow the wheels to spin at a limited speed, you can
enable Slip Start. Slip Start can be enabled at any
speed, however it is less effective at higher speeds.
Under normal conditions, Slip Start should not be
enabled. Enable it only in circumstances where you
deliberately want the wheels to spin, such as:
• Starting on a loose surface, such as gravel or snow.
• Driving in deep snow, sand or mud.
• Rocking out of a hole or deep rut.

To allow the wheels to spin, touch Controls > Driving >
Traction Control > Slip Start.

The touchscreen displays an alert message (yellow tire
with letters TC crossed) when Slip Start is enabled.

Although Slip Start is automatically disabled the next
time you start Model 3, it is strongly recommended that
you disable it immediately after the circumstances that
required you to enable it have passed.

NOTE: Slip Start cannot be enabled when you are
actively using Traffic-Aware Cruise Control.
