thaw them. If they become worn or
damaged, install new blades or
blade inserts. See Wiper Blade
Replacement on page 10‑32
Windshield wipers work in all power
modes, except when the ignition is
set to LOCK/OFF. After the engine
is turned off, wipers will work in
Retained Accessory Power (RAP)
mode until a door is opened. See

5-16 Instruments and Controls
Traction Control System
(TCS)/StabiliTrak®Light
The StabiliTrak system or the
Traction Control System (TCS)
indicator/warning light comes on
briefly while starting the engine.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light will then go off.
The indicator/warning light flashes
while the StabiliTrak or TCS system
is working to control the vehicle on
a low traction surface.
If the TCS warning light comes on
and stays on while driving, the
vehicle needs service.The light comes on when the TCS
and the StabiliTrak system is turned
off. If the TCS is off, wheel spin is
not limited. If the StabiliTrak system
is off, the system does not assist in
controlling the vehicle. Turn on the
TCS and the StabiliTrak system and
the warning light turns off.
See
StabiliTrak System
on
page 9‑53and Traction Control
System (TCS)on page 9‑52for
more information
Tire Pressure Light
For vehicles with a tire pressure
monitoring system, this light comes
on briefly when the engine is
started. It provides information
about tire pressures and the Tire
Pressure Monitoring System. When the Light is On Steady
This indicates that one or more
of the tires are significantly
underinflated.
A tire pressure message in the
Driver Information Center (DIC),
can accompany the light. See
Tire
Messages
on page 5‑25for
more information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the tire
loading information label. See Tire
Pressure
on page 10‑51for more
information.
When the Light Flashes First and
Then is On Steady
This indicates that there may be
a problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays on
steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
See Tire Pressure Monitor
Operation
on page 10‑53for
more information.

9-4 Driving and Operating
That could be a lot of distance in
an emergency, so keeping enough
space between the vehicle and
others is important.
And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition
of the road, whether it is wet, dry,
or icy; tire tread; the condition of the
brakes; the weight of the vehicle;
and the amount of brake force
applied.
Avoid needless heavy
braking. Some people drive in
spurts—heavy acceleration
followed by heavy braking —rather
than keeping pace with traffic. This
is a mistake. The brakes might not
have time to cool between hard
stops. The brakes will wear out
much faster with a lot of heavy
braking. Keeping pace with the
traffic and allowing realistic following
distances eliminates a lot of
unnecessary braking. That means
better braking and longer brake life. If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push
down. If the engine stops, there will
still be some power brake assist but
it will be used when the brake is
applied. Once the power assist is
used up, it can take longer to stop
and the brake pedal will be harder
to push.
Adding non‐dealer/non‐retailer
accessories can affect vehicle
performance. See
Accessories and
Modifications on page 10‑3.
Steering
Power Steering
If power steering assist is lost
because the engine stops or the
power steering system is not
functioning, the vehicle can be
steered but it will take more effort.
Steering Tips
It is important to take curves at a
reasonable speed.
Traction in a curve depends on the
condition of the tires and the road
surface, the angle at which the
curve is banked, and vehicle speed.
While in a curve, speed is the one
factor that can be controlled.
If there is a need to reduce speed,
do it before entering the curve, while
the front wheels are straight.
Try to adjust the speed so you can
drive through the curve. Maintain a
reasonable, steady speed. Wait to
accelerate until out of the curve, and
then accelerate gently into the
straightaway.
