Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
When you apply your brakes, cruise control is turned off.
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
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.
If your vehicle is in cruise control when the traction
control system (if equipped) begins to limit wheel spin,
the cruise control will automatically disengage.SeeTraction Control System (TCS) on page 4-9. When
road conditions allow you to safely use it again, you
may turn the cruise control back on.
The cruise control buttons
are located on left side of
the steering wheel.
T(On/Off):Press this button to turn cruise control
on and off. The indicator will be lit when cruise control
is on.
+ RES (Resume/Accelerate):Press this button to
make the vehicle accelerate or resume to a previously
set speed.
SET–:Press this button to set the speed or make the
vehicle decelerate.
[(Cancel):Press this button to cancel cruise control.
3-11

Setting Cruise Control
Cruise control will not work if your parking brake is set,
or if the master cylinder brake uid level is low.
The cruise control light on the instrument panel cluster
will come on after the cruise control has been set to
the desired speed.
{CAUTION:
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. Press the cruise control on/off button.
2. Get up to the speed you want.
3. Press and release the SET– button located on the
steering wheel.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This shuts off the
cruise control. But you do not need to reset it.
Once you are driving about 25 mph (40 km/h) or
more, press the +RES button on your steering wheel.
The vehicle will go back to your chosen speed and
stay there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until you reach your new desired speed,
then release it.
To increase vehicle speed in small increments,
press the +RES button.
3-12

Reducing Speed While Using Cruise
Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the steering
wheel until you reach the lower speed you want,
then release it.
To slow down in very small amounts, press the
SET– button on the steering wheel briey.
Each time you do this, you will go about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase vehicle speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to
step on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control.
Many drivers nd this to be too much trouble and do not
use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[(cancel) button on the steering wheel.
Press theT(on/off) button on the steering
wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.

How the System Works when Backing
If the shift lever is in REVERSE (R), URPA detects
objects close to the rear bumper. The rst time an object
is detected a single beep will sound. If an object is
detected at a REVERSE (R) speed between 0 mph
(0 km/h) and 5 mph (8 km/h), the following describes
what will occur based on your distance to a detected
object located behind the vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will be lit.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be lit.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/amber/red)
will be lit.
At distances less than 12 inches (0.3 m), a beeping
sound will repeat for a short time and all three lights
(amber/amber/red) will be lit and ashing.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on the
rear URPA display when the shift lever is moved into
REVERSE (R). This occurs under the following conditions:
The driver disables the system. SeeDIC Controls
and Displays on page 3-50.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your trunk during
your last drive when you turned off the vehicle.
If the attached objects are removed from your
vehicle before the start of your next drive,
the system will return to normal operation unless
an object is detected when the vehicle is shifted into
REVERSE (R). If this occurs, URPA assumes the
object is still attached, so you will have to wait until
the vehicle is driven forward above 15 mph (25 km/h)
before URPA will return to normal operation.
3-20

The ultrasonic sensors are not kept clean. So, be
sure to keep your vehicle’s rear bumper free of mud,
dirt, snow, ice, and slush. For cleaning instructions,
seeWashing Your Vehicle on page 5-87. If the DIC
still displays the PARK ASSIST OFF message after
cleaning the bumper and driving forward at a speed
of at least 15 mph (25 km/h), see your dealer.
Other conditions that may affect system performance
include vibrations from a jackhammer or the
compression of air brakes on a very large truck or
other mechanical devices that interfere with URPA
performance.
When URPA is disabled without driver action and the
driver attempts to turn URPA back on using the
Driver Information Center (DIC), the PARK ASSIST
ON option will not be selectable if the necessary
conditions stated above for normal system operation
are not met.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.
For Driver Information Center messages related to
URPA, seeDIC Warnings and Messages on page 3-56.
If the bumper is damaged, your URPA system may
not work properly. Take the vehicle to your dealer
to repair the system.
Accessory Power Outlet(s)
The accessory power outlets can be used to plug in
electrical equipment such as a cellular telephone or
CB radio.
Your vehicle has two power outlets. One is located next
to the ashtray and the other is located on the right
forward lower edge of the driver’s seat.
Your vehicle may have a small cap that must be pulled
down to access the accessory power outlet. If it does,
when not using the outlet be sure to cover it with
the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible to
the accessory power outlets and could result in blown
vehicle or adapter fuses. If you experience a problem
see your dealer for additional information on the
accessory power outlets.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to RUN. If it does not come on then, have it
xed so it will be ready to warn you if there’s a problem.When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does
not release fully. If it stays on after your parking brake
is fully released, it means you have a brake problem.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice that the
pedal is harder to push, or the pedal may go closer to
the oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing Your
Vehicle on page 4-34.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed
for service. United StatesCanada

on for several seconds.
That’s normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you’re driving, stop as soon
as possible and turn the ignition off. Then start the
engine again to reset the system. If the light still stays
on, or comes on again while you’re driving, your vehicle
needs service. If the regular brake system warning
light isn’t on, you still have brakes, but you don’t have
anti-lock brakes. If the regular brake system warning
light is also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes.
SeeBrake System Warning Light on page 3-40.
The anti-lock brake system warning light will come on
briey when you turn the ignition key to RUN. This is
normal. If the light doesn’t come on then, have it xed so
