1-30 In Brief
Ultrasonic Parking Assist
If available, Ultrasonic Rear Parking
Assist (URPA) system uses sensors
on the rear bumper to assist with
parking and avoiding objects while
in R (Reverse). It operates at
speeds less than 8 km/h (5 mph).
URPA uses audible beeps to
provide distance and system
information.
Keep the sensors on the vehicle's
rear bumper clean to ensure proper
operation.
SeeUltrasonic Parking Assist on
page 9‑68 for more information.
Power Outlets
Accessory power outlets can
be used to plug in electrical
equipment, such as a cell phone,
MP3 player, etc. The vehicle may have two
accessory power outlets located
below the climate control system,
or may have one accessory power
outlet and one cigarette lighter.
The cigarette lighter is designed to
fit only in the receptacle closest to
the driver.
There may be another accessory
power outlet in the rear cargo area.
If the vehicle has a floor console,
there is an accessory power outlet
inside the storage bin and one on
the rear of the floor console.
The accessory power outlets are
powered, even when the ignition is
in LOCK/OFF. Continuing to use
power outlets while the ignition is in
LOCK/OFF may cause the vehicle's
battery to run down.
See
Power Outlets on page 5‑10.
Universal Remote System
Vehicles with the Universal Remote
System will have these buttons
located in the headliner.
This system provides a way to
replace up to three remote control
transmitters used to activate
devices such as garage door
openers, security systems, and
home automation devices.
Read the instructions completely
before attempting to program the
transmitter. Because of the steps
involved, it may be helpful to
have another person assist with
programming the transmitter.
SeeUniversal Remote System on
page 5‑60.

5-26 Instruments and Controls
Emissions Inspection and
Maintenance Programs
Some local governments may have
programs to inspect the on-vehicle
emission control equipment.
For the inspection, the emission
system test equipment is connected
to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off. See your
dealer for assistance in verifying
proper operation of the
malfunction indicator lamp.
.The OBD II (On-Board
Diagnostics) system
determines that critical
emission control systems
have not been completely
diagnosed. The vehicle would be
considered not ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down.The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.
Brake System Warning
Light
With the ignition on, the brake
system warning light comes on
when the parking brake is set. If the
vehicle is driven with the parking
brake engaged, a chime sounds
when the vehicle speed is greater
than 8 km/h (5 mph).

Universal Remote System
Programming
Vehicles with the Universal Remote
System will have these buttons
located in the headliner.
This system provides a way to
replace up to three remote control
transmitters used to activate devices such as garage door
openers, security systems, and
home automation devices.
Do not use this system with any
garage door opener that does not
have the stop and reverse feature.
This includes any garage door
opener model manufactured before
April 1, 1982.
Read the instructions completely
before attempting to program the
transmitter. Because of the steps
involved, it may be helpful to
have another person assist with
programming the transmitter.
Be sure to keep the original remote
control transmitter for use in other
vehicles, as well as for future
programming. Only the original
remote control transmitter is needed
for Fixed Code programming.
The programmed buttons should be
erased when the vehicle is sold
or the lease ends. See
“Erasing
Universal Home Remote Buttons”
in this section. Park the vehicle outside of the
garage when programming a garage
door. Be sure that people and
objects are clear of the garage door
or gate that is being programmed.
Programming Universal Home
Remote
—Rolling Code
For questions or help programming
the Universal Home Remote
System, call 1-866-572-2728 or
go to www.learcar2u.com.
Most garage door openers sold
after 1996 are Rolling Code units.
Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.
