Driving and Operating
When the system activates, the
TCS/StabiliTrak warning light
flashes on the instrument panel
cluster. You may also hear a noise
or feel vibration in the brake pedal.
This is normal. Continue to steer the
vehicle in the intended direction.
If there is a problem detected
with StabiliTrak, a SERVICE
STABILITRAK message displays on
the DIC and the StabiliTrak/TCS
warning light on the instrument
panel cluster comes on. When this
message and warning light display,
the system is not operational.
Driving should be adjusted
accordingly. See Ride Control

Engine Drag Control (EDC)
EDC improves vehicle stability by
sensing if there is a difference in
speed between the free rolling front
wheels and the rear drive wheels
that often occurs when the driver
takes their foot off the accelerator
pedal on slippery surfaces (snow,
ice, etc.). When this is detected,
EDC sends more torque to the rear
wheels to make sure all four wheels
are spinning at similar speeds,
making the vehicle more stable.

Launch Control are systems
designed to allow increased
performance while accelerating and/

modes are for use at a closed
