Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside
the vehicle. It may also start the vehicle’s heating or air
conditioning systems, rear window defogger, and
heated seats. SeeHeated Seats on page 1-4and
Heated and Cooled Seats on page 1-5for additional
information. When the remote start system is active, the
climate control system will heat or cool the inside of
the vehicle at the setting the vehicle was set to when the
vehicle was last turned off. The rear window defogger
will be turned on by the climate control system when it is
cold outside. If the vehicle has heated seats, they
may also turn on when it is cold outside. Cooled seats
are not activated during a remote start. Normal
operation of the system will return after the key is
turned to the ON/RUN position.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using the remote start to have the vehicle in
view when doing so. Check local regulations for
any requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.If your vehicle has remote start, the RKE transmitter
provides an increased range of operation. However, the
range may be less while the vehicle is running. As a
result, you may need to be closer to your vehicle to turn
it off than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-4for additional
information.
/(Remote Start):This button will be on the RKE
transmitter if you have remote start.
To start the vehicle using the remote start feature:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button,
then immediately press and hold the transmitter’s
remote start button until the turn signal lights
ash or if the vehicle’s lights are not visible, press
and hold the remote start button for at least
four seconds. The vehicle’s doors will lock.
When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.
3. If it is the rst remote start since the vehicle has been
driven, repeat these steps, while the engine is still
running, to extend the engine running time by
10 minutes. Remote start can be extended one time.

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
In order to shift out of PARK (P), ignition must be in the
ON/RUN and the regular brake pedal must be applied.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.A (LOCK/OFF):This is the only position in which the
ignition key can be inserted or removed. This position
locks the ignition and transmission and steering column.
It is a theft-deterrent feature.
If the steering wheel is locked, move it from right to left
and turn the key to ACC/ACCESSORY. If none of
this works, then your vehicle needs service.
B (ACC/ACCESSORY):This position lets the radio and
windshield wipers operate while the engine is off. To
use ACC/ACCESSORY, turn the key clockwise.
C (ON/RUN):This position is where the key returns to
after the vehicle is started. This position displays
some of the warning and indicator lights.
The battery could be drained if you leave the key in the
ACC/ACCESSORY or ON/RUN position with the engine
off. You may not be able to start your vehicle if the battery
is allowed to drain for an extended period of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER DOOR OPEN
when the driver’s door is opened if the ignition is in
LOCK/OFF, ACC/ACCESSORY and the key is in the
ignition. SeeDIC Warnings and Messages on page 3-56
for more information.

Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the
key in the ignition and park your vehicle, a chime
will sound, when you open the driver’s door. Always
remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for an
extended period of time.
Retained Accessory Power (RAP)
The following accessories on your vehicle can be used
for up to 10 minutes after the engine is turned off.
Audio System
Audio Steering Wheel (if equipped)
Clock
Power Windows
Sunroof (if equipped)
Power to these accessories works up to 10 minutes or
until the driver’s door is opened.The instrument panel cluster lights stay on for a few
seconds, then will go out. Once the driver’s door
is opened, the power shuts off to these accessories.
Your vehicle has a feature designed to protect the
battery against drainage. For more information
seeInadvertent Power Battery Saver on page 3-19and
Electric Power Management on page 3-19.
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position – this is a
safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking Assist
(URPA) system, it helps you park easier and avoid other
vehicles while in REVERSE (R). It operates at speeds
less than 5 mph (8 km/h). It can determine how
close objects are to the rear bumper, up to 8 feet (2.5 m)
behind your vehicle. The distance sensors are located
on the rear bumper.
{CAUTION:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision. It
cannot detect:
objects that are below the bumper,
underneath the vehicle, or if they are too
close or far from the vehicle
children, pedestrians, bicyclists, or pets.
CAUTION: (Continued)
CAUTION: (Continued)
If you do not use proper care before and while
backing; vehicle damage, injury, or death
could occur. Even with URPA, always check
behind your vehicle before backing up. While
backing, be sure to look for objects and check
your vehicle’s mirrors.
The display is located on
the rear shelf, below the
rear window, and can
be seen by looking over
your right shoulder.
URPA uses three color-coded lights to provide distance
and system information.
2-39

How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R). The rear display will then
briey illuminate to let you know the system is working.
URPA operates only at speeds less than 5 mph
(8 km/h). If you are above this speed, the red light on
the rear display will ash.
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below trunk level. Objects
must also be within 8 feet (2.5 m) from your rear
bumper. This distance may be less during warmer or
humid weather.
A single beep will sound the rst time an object is
detected between 20 inches (0.5 m) and 8 feet (2.5 m)
away. Beeping will occur for three seconds when
you are closer than 1 foot (0.3 m) from the object.
The following describes what will occur with the URPA
display as you get closer to a detected object:
Description English Metric
amber light 8 ft 2.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights 23 in 0.6 m
amber/amber/red lights
ashing and beep for
three seconds1 ft 0.3 mThe system can be disabled through the Driver
Information Center (DIC). See “Park Assist” underDIC
Operation and Displays on page 3-49for more
information.
When the System Does Not Seem to
Work Properly
The driver disables the system.
The parking brake pedal is depressed.
The ultrasonic sensors are not clean. Keep your
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-98.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your trunk during
your 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 your 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 your vehicle to your
dealer/retailer.
