control will disengage. Cruise control
may be turned back on when road
conditions allow.
Both systems come on automatically
when the vehicle is started and begins
to move. The systems may be heard or
felt while they are operating or while
performing diagnostic checks. This is
normal and does not mean there is a
problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary to
turn TCS off if the vehicle gets stuck
in sand, mud, ice, or snow. SeeIf the
Vehicle Is Stuck 0179 and “Turning
the Systems Off and On ”later in this
section.
The indicator light for both systems is
in the instrument cluster. This
light will:
. Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak/ESC is
activated.
. Turn on and stay on when either
system is not working.

Magnetic Ride Control
If equipped, the Magnetic Ride Control
monitors the suspension system.
Based on road conditions, steering
wheel angle, and vehicle speed, the
system automatically adjusts to
provide the best handling while
providing a smooth ride. The Tour and
Sport Modes will feel similar on a
smooth road.
Tour : Use for normal city and
highway driving. This setting provides
a smooth, soft ride.
Sport : Use where road conditions or
personal preference demand more
control. This setting provides more
“feel,” or response to road conditions. The vehicle is normally in Tour Mode.
Sport Mode is engaged when the shift
lever is placed in M (Manual Mode).
When the shift lever is placed in D
(Drive) the system will revert back to
Tour Mode.
The Driver Information Center (DIC)
may briefly display a message on
vehicle startup or when a new mode is
selected.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow, mud,
ice, sand or gravel. When traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. The limited-slip rear axle
also gives the driver enhanced control
when cornering hard or completing a
maneuver, such as a lane change.
