Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-31.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-24.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. Do not leave your vehicle when the engine
is running unless you have to. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) on page 2-29.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-36.

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.
