9-22 Driving and Operating
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in 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.(Continued)
WARNING (Continued)
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause your
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 your 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 your 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. SeeTireson
page 10‑44.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving.
If you become tired or sleepy, find a
safe place to park your vehicle
and rest.

9-24 Driving and Operating
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C
(32°F) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.
Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.The
Antilock Brake System (ABS)
on page 9‑50improves vehicle
stability during hard stops on
slippery roads, but apply the brakes
sooner than when on dry pavement.
Allow greater following distance on
any slippery road 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, if equipped,
on slippery surfaces.Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use the Roadside
Service
on page 13‑5. To get help
and keep everyone in the
vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
(Continued)

Driving and Operating 9-53
Examples of these conditions
include hard acceleration in a turn,
an abrupt upshift or downshift of the
transmission or driving on rough
roads.
If cruise control is being used when
TCS begins to limit wheel spin,
the cruise control automatically
disengages. The cruise control
can be re-engaged when road
conditions allow. SeeCruise Control
on page 9‑57for more information.
TRACTION FAILED appears on the
Driver information Center (DIC)
when a TCS or antilock brake
system problem has been detected
and the vehicle needs service.
When this message is on, the
system will not limit wheel spin.
Adjust your driving accordingly.
See Driver Information Center (DIC)
on page 5‑18for more information.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle
is stuck in sand, mud, ice, or snow, and it is necessary to
“rock”the
vehicle to attempt to free it. See If
the Vehicle is Stuck
on page 9‑26for more information.
To turn the system off, press and
release the TCS/StabiliTrak button.
When TCS has been turned off, this
light comes on steady and TRAC
OFF appears on the DIC. This light
flashes when TCS is active.
Press and release the
TCS/StabiliTrak button again to
turn the system back on. The TRAC
OFF message then goes off. TCS automatically comes on
whenever the vehicle is started and
resets itself at each ignition cycle.
Adding non‐dealer/non‐retailer
accessories can affect the vehicle's
performance. See
Accessories and
Modifications on page 10‑3.
StabiliTrak System
The vehicle has a vehicle stability
enhancement system called
StabiliTrak. It is an advanced
computer controlled system that
assists the driver with directional
control of the vehicle in difficult
driving conditions.
StabiliTrak activates when the
computer senses a difference
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any
one of the vehicle's brakes to assist
the driver with keeping the vehicle
on the intended path.

9-54 Driving and Operating
When the vehicle is started and
begins to move, the system
performs several diagnostic checks
to insure there are no problems.
The system may be heard or felt
while it is working. This is normal
and does not mean there is a
problem with the vehicle.
If cruise control is being used when
StabiliTrak activates, the cruise
control automatically disengages.
The cruise control can be
re-engaged when road conditions
allow. SeeCruise Control
on
page 9‑57.
If there is a problem detected with
StabiliTrak, a SERVICE STAB SYS
message displays on the Driver
Information Center (DIC). See
Driver Information Center (DIC)
on
page 5‑18for more information.
When this message is displayed,
the system is not working. Adjust
your driving accordingly. StabiliTrak comes on automatically
whenever the vehicle is started and
resets itself at each ignition cycle.
However, when the transfer case is
placed in Four‐Wheel‐Low Lock
mode, StabiliTrak is automatically
disabled. See
Four-Wheel Drive
on
page 9‑46for more information.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle
is stuck in sand, mud, ice, or snow,
and it is necessary to “rock”the
vehicle to attempt to free it. See If
the Vehicle is Stuck
on page 9‑26.
This light comes on steady when
TCS has been turned off. This light
flashes when StabiliTrak is active. To Turn off TCS and StabiliTrak,
press and hold the TCS/StabiliTrak
button until STAB SYS OFF
displays on the DIC. Press and
release the TCS/StabiliTrak button
again to turn StabiliTrak back on.
Locking Rear Axle
For vehicles with this feature,
additional traction can be obtained
from the rear wheels when traveling
in off-road situations such as mud,
snow, sand, steep hills and uneven
terrain.
The button used to turn this
feature on or off is located on the
instrument panel.

Driving and Operating 9-57
Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
9(Off): Turns the cruise control
system off.
R (On): Turns the cruise control the
system on.
S(Resume/Accelerate): Makes
the vehicle accelerate or resume to
a previously set speed.
rT (Set): Press this button to set
the speed.
Cruise control will not work if the
parking brake is set, or if the master
cylinder brake fluid level is low.
If the brakes are applied, the cruise
control shuts off.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
(Continued)
WARNING (Continued)
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
The cruise control disengages, if the
vehicle has the Traction Control
System (TCS) and it begins to limit
wheel spin. See Traction Control
System (TCS)
on page 9‑52.
When road conditions allow the
cruise control to be safely used
again, it can be turned back on.

9-58 Driving and Operating
Setting Cruise Control
{WARNING
If you leave your cruise control on
when you are not using cruise,
you might hit a button and go into
cruise when you do not want to.
You could be startled and even
lose control. Keep the cruise
control switch off until you want to
use cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed desired. 3. Press
Tat the end of the lever
and release it.
4. Take your foot off the accelerator pedal.
The cruise symbol on the instrument
panel comes on when the cruise
control is engaged. Resuming a Set Speed
Suppose the cruise control is set at
a desired speed and then you apply
the brake or step on the clutch. This
disengages the cruise control. But it
does not need to be reset.
Once the vehicle is going about
40 km/h (25 mph) or more, move
the cruise control switch briefly
from
RtoS.
The vehicle goes back to the
chosen speed and stays there.
If the switch is held at resume/
accelerate the vehicle keeps going
faster until the switch is released or
the brake is applied. Do not hold the
switch at resume/accelerate, unless
you want the vehicle to go faster.

Driving and Operating 9-59
Increasing Speed While Using
Cruise Control
There are two ways to go to a
higher speed:
.Use the accelerator pedal
to get to the higher speed.
Press
Tat the end of the
lever, then release the button
and the accelerator pedal. The
vehicle will now cruise at the
higher speed. If the accelerator
pedal is held longer than
60 seconds, cruise control will
turn off.
.Move the cruise switch
from
RtoS. Hold it there until
the desired speed is reached,
and then release the switch.
To increase the vehicle speed in
small amounts, move the switch
briefly to resume/accelerate.
Each time this is done, the
vehicle goes about 1.6 km/h
(1 mph) faster. Reducing Speed While Using
Cruise Control
.Press and holdTuntil the
desired lower speed is reached,
then release it.
.To slow down in very small
amounts, briefly press
T. Each
time this is done, the vehicle
goes about 1.6 km/h (1 mph)
slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle slows down to the cruise
control speed set earlier. Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle's
speed, load, and the steepness of
the hills. When going up steep hills,
the accelerator pedal might have to
be used to maintain the vehicle
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep the vehicle
speed down. When the brake is
applied the cruise control will
turn off.
