194 DRIVING AND OPERATING
these types of driving conditions and
avoid driving through large puddles
and deep-standing or flowing water.
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick
stop and could cause pulling to one
side. You could lose control of the
vehicle.
After driving through a large puddle
of water or a car/vehicle wash,
lightly apply the brake pedal until
the brakes work normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be very
cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can
build up under the vehicle's tires so
they actually ride on the water. This
can happen if the road is wet enough
and you are going fast enough. When
the vehicle is hydroplaning, it has
little or no contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
. Pass with caution.
. Keep windshield wiping equipment
in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper tread
depth. See Tires0339.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving on
flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the vehicle
on a long downhill slope can cause
brake overheating, can reduce brake
performance, and could result in a
loss of braking. Shift the
transmission to a lower gear to let
the engine assist the brakes on a
steep downhill slope.

DRIVING AND OPERATING 195
{Warning
Coasting downhill in N (Neutral) or
with the ignition off is dangerous.
This can cause overheating of the
brakes and loss of steering assist.
Always have the engine running
and the vehicle in gear.
. Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills; something
could be in your lane (e.g., stalled
car, crash).
. Pay attention to special road signs
(e.g., falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and the
road creates less traction or grip, so
drive carefully. Wet ice can occur at
about 0 °C (32 °F) when freezing rain
begins to fall. Avoid driving on wet ice
or in freezing rain until roads can be
treated.
For slippery road driving:
.Accelerate gently. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick.
. Turn on Traction Control. See
Traction Control/Electronic Stability
Control 0220.
. Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes should
be applied sooner than when on
dry pavement. See Antilock Brake
System (ABS) 0217.
See Driver Mode Control 0222. .
Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas. The
surface of a curve or an overpass
can remain icy when the
surrounding roads are clear. Avoid
sudden steering maneuvers and
braking while on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby. If possible,
use Roadside Service. See Roadside
Service 0405. To get help and keep
everyone in the vehicle safe:
. Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.

DRIVING AND OPERATING 217
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (ABS), an advanced electronic
braking system that helps prevent a
braking skid.
When the vehicle begins to drive
away, ABS checks itself. A momentary
motor or clicking noise may be heard
while this test is going on, and it may
even be noticed that the brake pedal
moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
0 143. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to avoid
a sudden obstacle, a computer senses
the wheels are slowing down. If one of
the wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure to
each wheel, as required, faster than
any driver could. This can help you
steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates on
wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the
time needed to get a foot up to the
brake pedal or always decrease
stopping distance. If you get too close
to the vehicle in front of you, there
will not be enough time to apply the
brakes if that vehicle suddenly slows
or stops. Always leave enough room
up ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the
brake pedal down firmly and let ABS
work. You may hear the ABS pump or
motor operating and feel the brake
pedal pulsate. This is normal.
When ABS is active, it may be an
indication that road surfaces are
slippery. Braking sooner may be
required for driving conditions.
If equipped with electric brake boost,
the TCS/StabiliTrak/ESC light will
flash when ABS is active.
Braking in Emergencies
ABS allows you to steer and brake at
the same time. In many emergencies,
steering can help more than even the
very best braking.

220 DRIVING AND OPERATING
Automatic Vehicle
Hold (AVH)
Automatic Vehicle Hold (AVH),
if equipped, can be turned on by
pressing AUTO HOLD with the driver
seat belt fastened, the driver door
closed, and the engine running. The
AVH indicator will come on.This feature will activate when the
vehicle is stopped to prevent it from
moving. After the brake pedal has
been released and before the
accelerator pedal has been pressed,
AVH uses braking pressure to hold the
vehicle stationary. In addition, the
ABS pump motor may activate to
build brake pressure to maintain the
vehicle at a standstill if necessary.
If AVH is holding the vehicle, the AVH
indicator will change to green. Once
AVH is active it will hold the vehicle
for a defined time period then engage
the parking brake. While AVH is
holding the vehicle, the parking brake
will engage if the driver door is
opened or the driver seat belt is
unfastened. See
Automatic Vehicle Hold
(AVH) Light 0144.
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak/
Electronic Stability Control (ESC).
These systems help limit wheel spin
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any of
the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to the
spinning wheels and reduces engine
power to limit wheel spin.
StabiliTrak/ESC activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak/ESC selectively applies
braking pressure to any one of the
vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.

Driver Mode Control
Driver Mode Control attempts to add
a sportier feel, provide a more
comfortable ride, or assists in different
weather conditions or terrain. This
system simultaneously changes the
software settings of various
sub-systems to optimize driving
performance. Depending on the option
package, available features, and mode
selection; the Exhaust, Suspension,
Steering, Brakes, and Powertrain will
change settings to achieve the desired
mode characteristics. If the vehicle is
equipped with Magnetic Ride Control,
selecting the various Driver Modes
adjusts the ride of the vehicle to
enhance the ride performance for the
road conditions and the
selected mode.
