See Section 2 of your Owner Manual.
Traction Control System
(2WD models)
The Traction Control System (TCS)
detects wheel spin at one or both rear
wheels and reduces engine power
and/or upshifts the transmission to help
limit wheel spin. The TCS is designed to
come on any time you start the engine.
Under most driving conditions, you
should leave the TCS turned on. But, if
your vehicle ever gets stuck in sand,
mud or snow and rocking the vehicle is
required, you may want to turn the TCS
system off. See Section 4 of your Owner
Manual for important details.
To turn the TCS system off
• Press the button located on the
instrument panel just above the radio.
The amber light is designed to come
on when the TCS system is turned
off.
• Press the button again to turn the
TCS system back on. The amber
light will turn off.
See Section 4 of your Owner Manual.

Automatic Locking Differential

Your axle may be equipped with an
automatic locking differential feature that
helps increase traction when traveling at
speeds less than 20 mph.
