The traction control system automatically comes
on whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to.
You can turn the system on or off at any time by pressing
the traction control system button located on the console
or on the end of the column shifter. The DIC will display
TRACTION CONTROL OFF when you press the button,
and part of the traction control system is disabled. Your
vehicle will still have brake-traction control, but will not
be able to use the engine speed management system.
You may still hear system noises as a result of the
brake-traction control coming on. If the controller detects
excessive wheel spin in this mode, the traction control
system and StabiliTrak
®
indicator 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 your vehicle is stuck in sand, mud,
ice or snow, and you may want to “rock” your vehicle
in an attempt to free it. See If Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow on page 4-19 for more
information.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. See Accessories and
Modifications on page 5-3 for more information.
Magnetic Ride Control
Your vehicle may have a feature called Magnetic Ride
Control that automatically adjusts the ride of your vehicle.
Automatic ride control is achieved through a computer
used to control and monitor the suspension system.
The controller receives input from various sensors to
determine the proper system response. If the controller
detects a problem within the system, the DIC will display
a SERVICE SUSPENSION SYS message. See DIC
Warnings and Messages on page 3-73 for more
information. If this message appears, have your
vehicle serviced at your dealer/retailer.
Electronically Controlled Air Ride
Suspension
If you have a Professional Vehicle, you may have a
feature called Electronically Controlled Air Suspension.
Air ride control is achieved through a computer used to
control and monitor the system. The controller receives
input from two height sensors to determine the proper
system response. If the controller detects a problem
with the system, the Driver Information Center (DIC)
will display a SERVICE SUSPENSION SYS message.
If this message appears, have your vehicle serviced at
your dealer/retailer.
