Road Sensing Suspension
The Road Sensing Suspension (RSS) feature provides
superior vehicle ride and handling under a variety of
passenger and loading conditions.
The system is fully automatic and uses a computer
controller to continuously monitor vehicle speed, wheel
to body position, lift/dive and steering position of the
vehicle. The controller then sends signals to each shock
absorber to independently adjust the damping level to
provide the optimum vehicle ride.
RSS also interacts with the tow/haul mode that, when
engaged, will provide additional control of the shock
absorbers. This additional control results in better ride
and handling characteristics when the vehicle is loaded
or towing a trailer. See “Tow/Haul Mode” under Towing a
Trailer on page 4-43.
StabiliTrak
®
System
Your vehicle may be equipped with the StabiliTrak
®
system which combines antilock brake, traction and
stability control systems and helps the driver maintain
directional control of the vehicle in most driving
conditions.
When you first start your vehicle and begin to drive
away, the system performs several diagnostic checks to
ensure there are no problems. You may hear or feel the
system working. This is normal and does not mean there
is a problem with your vehicle. The system should
initialize before the vehicle reaches 20 mph (32 km/h).
In some cases, it may take approximately two miles of
driving before the system initializes.
If the system fails to turn on or activate, the StabiliTrak
®
light along with one of the following messages will be
displayed on the Driver Information Center (DIC):
TRACTION CONTROL OFF, SERVICE TRACTION
CONTROL, STABILITRAK OFF, SERVICE
STABILITRAK. If these DIC messages appear, make
sure the StabiliTrak
®
system has not been turned off
using the StabiliTrak
®
on/off button. Then turn the
steering wheel clockwise from the nine o’clock position to
the three o’clock position. If this clears the message(s),
your vehicle does not need servicing. If this does not
clear the message(s), then turn the vehicle off, wait
15 seconds, and then turn it back on again to reset the
system. If any of these messages still appear on the
Driver Information Center (DIC), your vehicle should be
taken in for service. For more information on the DIC
messages, see Driver Information Center (DIC)
on page 3-45.
