When the System Does Not
Seem to Work Properly
If the URPA system does not
activate due to a temporary
condition, the message PARK
ASSIST OFF displays on the DIC
and a red light will be shown on the
rear URPA display when the shift
lever is moved into R (Reverse).
This may occur under the following
conditions:
The driver disables the system.
The ultrasonic sensors are
not clean. Keep the vehicle’s rear
bumper free of mud, dirt, snow,
ice and slush. For cleaning
instructions, seeWashing Your
Vehicle on page 5-81.
A trailer was attached to the
vehicle, or a bicycle or an object
was hanging out of the liftgate
during the last drive cycle, the red
light may illuminate in the rear
display. Once the attached object
is removed, URPA will return to
normal operation.
A tow bar is attached to the
vehicle.
The vehicle’s bumper is
damaged. Take the vehicle to
your dealer/retailer to repair the
system.
Other conditions may affect
system performance, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck.
If the system is still disabled, after
driving forward at least 15 mph
(25 km/h), take the vehicle to your
dealer/retailer.
Rear Vision
Camera (RVC)
The vehicle may have a Rear Vision
Camera system. Read this entire
section before using it.
{CAUTION
The Rear Vision Camera (RVC)
system does not replace driver
vision. RVC does not:
Detect objects that are
outside the camera’s eld of
view, below the bumper, or
underneath the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
Do not back the vehicle by only
looking at the rear vision camera
screen, or use the screen during
longer, higher speed backing
maneuvers or where there could
be cross-traffic. Your judged
distances using the screen will
differ from actual distances.

Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal 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 brakes are applied
the cruise control is disengaged.

Brake System Warning
Light
This vehicle’s hydraulic brake
system is divided into two parts.
If one part is not working, the other
part can still work and stop the
vehicle. For good braking both
parts need to be working.
If the warning light comes on,
there is a brake problem. Have the
brake system inspected right away.
{CAUTION
The brake system might not be
working properly if the brake
system warning light is on. Driving
with the brake system warning light
on can lead to a crash. If the light
is still on after the vehicle has been
pulled off the road and carefully
stopped, have the vehicle towed
for service.
This light should come on briey
when the ignition key is turned to
ON/RUN. If it does not come on then,
have it xed so it will be ready to
warn if there is a problem.
This light can also come on due
to low brake uid. SeeBrakes
on page 5-25for more information.When the ignition is on, the brake
system warning light will also come
on when the parking brake is set.
The light will stay on if the parking
brake does not release fully. If it
stays on after the parking brake is
fully released, it means there is a
brake problem.
If the light comes on while driving,
pull off the road and stop carefully.
Make sure the parking brake is
fully released. The pedal, might
be harder to push or, the pedal
can go closer to the oor. It could
take longer to stop. If the light is
still on, have the vehicle towed for
service. SeeTowing Your Vehicle
on page 4-21.

Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briey when the engine is started.
If the light does not come on, have
it xed so it will be ready to warn
if there is a problem.
If the ABS light stays on, turn the
ignition off. If the light comes on while
driving, stop as soon as it is safely
possible and turn the ignition off.A chime may also sound when the
light comes on steady. Then start
the engine again to reset the system.
If the ABS light stays on, or comes
on again while driving, the vehicle
needs service. If the regular brake
system warning light is not on, the
vehicle still has brakes, but not
antilock brakes. If the regular brake
system warning light is also on,
the vehicle does not have antilock
brakes and there is a problem with
the regular brakes. SeeBrake
System Warning Light on page 3-36.
For vehicles with a Driver
Information Center (DIC),
seeDIC Warnings and Messages
on page 3-56for all brake related
DIC messages.
StabiliTrak®Indicator
Light
This light comes on briey while
starting the engine. If it does not,
have the vehicle serviced by your
dealer/retailer. If the system is
working normally the indicator
light goes off.
If it stays on, or comes on while
driving, there could be a problem
with the StabiliTrak system and the
vehicle might need service. When
this warning light is on, the system
is off and will not limit wheel spin.
Instrument Panel 3-37

Police records show that
almost 40 percent of all motor
vehicle-related deaths involve
alcohol. In most cases, these deaths
are the result of someone who
was drinking and driving. In recent
years, more than 17,000 annual
motor vehicle-related deaths have
been associated with the use of
alcohol, with about 250,000 people
injured.
For persons under 21, it is against
the law in every U.S. state to drink
alcohol. There are good medical,
psychological, and developmental
reasons for these laws.
The obvious way to eliminate the
leading highway safety problem
is for people never to drink alcohol
and then drive.
Medical research shows that alcohol
in a person’s system can make crash
injuries worse, especially injuries
to the brain, spinal cord, or heart.This means that when anyone who
has been drinking — driver or
passenger — is in a crash, that
person’s chance of being killed or
permanently disabled is higher than
if the person had not been drinking.
Control of a Vehicle
The following three systems
help to control the vehicle while
driving — brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of the
vehicle. SeeStabiliTrak
®System on
page 4-5.
Adding non-dealer/non-retailer
accessories can affect vehicle
performance. SeeAccessories and
Modifications on page 5-3.
Braking
SeeBrake System Warning Light on
page 3-36.
Braking action involves perception
time and reaction time. Deciding
to push the brake pedal is
perception time. Actually doing
it is reaction time.
Average reaction time is about
three-fourths of a second. But
that is only an average. It might be
less with one driver and as long as
two or three seconds or more with
another. Age, physical condition,
alertness, coordination, and eyesight
all play a part. So do alcohol, drugs,
and frustration. But even in
three-fourths of a second, a vehicle
moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of
distance in an emergency, so
keeping enough space between the
vehicle and others is important.
Driving Your Vehicle 4-3

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. SeeAccessories and
Modifications on page 5-3.
Antilock Brake
System (ABS)
This vehicle has the Antilock
Brake System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
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
on page 3-37.
Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you.
You slam on the brakes and continue
braking. Here is what happens
with ABS:
A computer senses that 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
the driver steer around the obstacle
while braking hard.
4-4 Driving Your Vehicle

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 rmly and let
antilock work. The antilock pump or
motor operating might be heard and
the brake pedal might be felt to
pulsate, but this is normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help more
than even the very best braking.
Brake Assist
This vehicle has a Brake Assist
feature designed to assist the
driver in stopping or decreasing
vehicle speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.Minor brake pedal pulsations or
pedal movement during this time
is normal and the driver should
continue to apply the brake pedal
as the driving situation dictates
The Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly decreased.
StabiliTrak®System
The vehicle has the StabiliTrak
system which combines antilock
brake, traction and stability control
systems and helps the driver
maintain directional control of the
vehicle in most driving conditions.
When you rst start the vehicle and
begin to drive away, the system
performs several diagnostic checks
to ensure there are no problems.
Driving Your Vehicle 4-5

It may also be necessary to turn off
the system when driving in extreme
off-road conditions where high wheel
spin is required. SeeIf Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow
on page 4-16.
Traction Control Operation
The traction control system is part
of the StabiliTrak system. Traction
control limits wheel spin by reducing
engine power to the wheels (engine
speed management) and by applying
brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is
enabled automatically when the
vehicle is started. It will activate
and the StabiliTrak light will ash
if it senses that any of the wheels
are spinning or beginning to lose
traction while driving. If traction
control is turned off, only the
brake-traction control portion of
traction control will work. The engine
speed management will be disabled.In this mode, engine power is not
reduced automatically and the driven
wheels can spin more freely. This
can cause the brake-traction control
to activate constantly.
Notice:If the wheel(s) of one axle
is allowed to spin excessively
while the StabiliTrak, ABS and
brake warning lights and any
relevant DIC messages are
displayed, the transfer case could
be damaged. The repairs would
not be covered by the vehicle
warranty. Reduce engine power
and do not spin the wheel(s)
excessively while these lights and
messages are displayed.
The traction control system may
activate on dry or rough roads or
under conditions such as heavy
acceleration while turning or
abrupt upshifts/downshifts of the
transmission. When this happens, a
reduction in acceleration may be
noticed, or a noise or vibration may
be heard. This is normal.If cruise control is being used when
the system activates, the StabiliTrak
light will ash and cruise control will
automatically disengage. Cruise
control may be reengaged when
road conditions allow. SeeCruise
Control on page 3-9.
StabiliTrak may also turn off
automatically if it determines that a
problem exists with the system.
If the problem does not clear itself
after restarting the vehicle, see your
dealer/retailer for service.
All-Wheel Drive (AWD)
System
If the vehicle has this feature, engine
power is sent to all four wheels when
extra traction is needed. This is like
four-wheel drive, but there is no
separate lever or switch to engage
or disengage the axle. It is fully
automatic, and adjusts itself as
needed for road conditions.
