T(On/Off):This button can both activate and
turn off the system. The indicator light is on
when cruise control is on and turns off when cruise
control is off.
+ RES (Resume/Accelerate):Press this button
to make the vehicle accelerate or resume to
a previously set speed.
SET−(Set/Coast):Press this button to set the
speed or make the vehicle decelerate.
[(Cancel):Press this button to cancel cruise
control without erasing the set speed from
memory.
Setting Cruise Control
Cruise control will not work if the 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 desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set the 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 the steering
wheel. The vehicle will go back to the previous set
speed and stay there.
219

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. Each time this is
done, the vehicle will go about 1 mph
(1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
To reduce the vehicle speed while using cruise
control:
Press and hold the SET– button on the
steering wheel until the desired lower speed is
reached, then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel
briey. Each time this is done, the vehicle will
go about 1 mph (1.6 km/h) 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 will slow down to the previous
set cruise speed.
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’s speed. When going
downhill, you might have to brake or shift to a
lower gear to keep the vehicle’s speed down. Of
course, applying the brake turns off the 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 the On/Off button on the
steering wheel.

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 screen and a
red light will come on the URPA display when the
shift lever is moved into REVERSE (R). This
occurs under the following conditions:
The driver disables the system.
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.
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 601. 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
by pressing the rear park aid button, the
indicator light will ash for 3 seconds and then
stay lit to indicate that URPA is off.
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.

Brake System Warning Light
With the ignition on, the brake system warning
light will come on when you set the parking brake.
If you try to drive with the parking brake engaged,
a chime will sound when the vehicle speed is
greater than 5 mph (8 km/h).
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 and a chime
sounds there could be a brake problem. Have
your brake system inspected right away.
This light may also come on due to low brake
uid. SeeBrakes on page 528for more
information.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 is a problem.
{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.
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 may go closer
to the oor. It may take longer to stop. If the
light is still on, have the vehicle towed for service.
