To turn the system off or
on, press and release this
button located in front of
the shift lever.
TCS automatically comes on whenever the vehicle
is started. To limit wheel spin, especially in slippery
road conditions, always leave the system turned on.
TCS can be turned off if needed.
The system can be turned on or off at any time by
pressing the TCS button. The DIC will display
TRACTION CONTROL OFF when the button is
pressed, and part of the traction control system is
disabled. The vehicle will still have brake-traction
control, but will not be able to use the engine speed
management system. System noises may be heard as
a result of the brake-traction control working. If the
controller detects excessive wheel spin in this mode,
the TCS/StabiliTrak light may blink.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn the
system off if the vehicle is stuck in sand, mud, ice or
snow, and you want to “rock” the vehicle to attempt to
free it. See If Your Vehicle is Stuck in Sand, Mud, Ice,
or Snow on page 5‑17.
Adding non‐dealer/non‐retailer accessories can affect
the vehicle's performance. See Accessories and
Modifications
on page 6‑3
for more information.
