Remote Vehicle Start
This feature allows you to start the engine from outside
the vehicle.
Before the remote vehicle start system can be operated,
it must be turned on through the vehicle personalization
system.
You can also program the remote vehicle start system to
start up the vehicle’s automatic climate control system. If
this feature is turned on, the system monitors the outside
temperature and turns on the rear window defogger, front
window defogger, and heated or ventilated seats, if your
vehicle has them. See “Personal Settings Menu” under
Vehicle Personalization on page 2-60.
/(Remote Start):This button will be on the RKE

2. Press the transmitter’s lock button, release it, and
then immediately press and hold the transmitter’s
remote start button for at least three seconds or until
the vehicle’s turn signal lamps ash. The vehicle’s
doors will be locked.
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.
If the vehicle is left running it will automatically shut off
after 10 minutes unless a time extension has been
done. To manually shut off a remote start, do one of the
following:

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, if the vehicle has one, the power
door lock switch, or the rear door manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert the key into the security lock slot and turn it
so the slot is in the vertical position.
Lockout Protection
Your vehicle can be programmed to sound the horn
three times and unlock the driver’s door when all doors
are closed and there is a keyless access transmitter
inside the interior of the vehicle. When the driver’s door
is reopened, the key in reminder chime will sound
continuously. The vehicle will remain locked only when
at least one transmitter has been removed from the
vehicle and both doors are closed. SeeVehicle
Personalization on page 2-60.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-38.
2-16

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 2-38.
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.
SeeWinter Driving on page 4-22.
{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
the parking brake after you 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 2-36.
If you are parking on a hill and if you are pulling a trailer,
also seeTowing a Trailer (Vehicles With Heavy Duty
Cooling) on page 4-34orTowing a Trailer (Vehicles
Without Heavy Duty Cooling) on page 4-40.

Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
Outside Power Heated Mirrors
The power mirror control
is on the driver’s door
armrest and controls
the driver’s side and
passenger’s side mirrors.
Move the selector switch left or right to choose the
driver’s side or passenger’s side mirror. Use the arrows
located on the control pad to adjust the position of
each mirror. Adjust each mirror so you can see the side
of your vehicle and the area behind your vehicle.Return the selector switch to the center position when
nished adjusting. This will prevent unwanted mirror
movement in case the control pad is accidentally
bumped while driving.
The preferred mirror positions can be stored with the
memory option. SeeMemory Seat, Mirrors and Steering
Wheel on page 2-77.
The mirrors can be manually folded inward to prevent
damage when going through car washes or conned
spaces. To fold, push the mirror toward the vehicle.
To return the mirror to its original position, push outward.
Be sure to return both mirrors to their original unfolded
position before driving.
When the rear window defogger is turned on, both
outside rear view mirrors are heated to help clear them
of ice, snow, or condensation. See “Rear Window
Defogger” underDual Climate Control System on
page 3-48.

Vehicle Personalization
Your vehicle has personalization that allows you to
program certain features to a preferred setting for up to
two drivers. The back of the keyless access transmitters
are labelled 1 or 2. Additional keyless access transmitters
programmed to the vehicle, as 3 and/or 4, do not have
a number on the back and are not capable of being
personalized. The number of programmable features
varies depending upon which vehicle options are
purchased.
On all vehicles, features such as climate control settings,
radio and XM™ preset settings, exterior lighting at unlock
and remote lock unlock conrmation, and language have
already been programmed for your convenience. Your
vehicle also has an automatic door locking feature that is
always on. You cannot turn the automatic door locking
feature off. SeeProgrammable Automatic Door Locks on
page 2-15.
Some vehicles have additional features that can be
programmed including the seat, steering column, and
outside rearview mirror position.If your vehicle has the base audio system, the following
information explains the vehicle personalization on
your vehicle.
If your vehicle has the Navigation system, see
“Personalization” in the Index of the Navigation System
manual for information on vehicle personalization.
If your vehicle has the ability to program additional
personalization features, the driver’s preferences
are recalled by pressing any button on the keyless
access transmitter, 1 or 2, by selecting Driver 1 or 2 on
the radio display, or when a valid keyless access
transmitter is detected upon opening the driver’s door.
If more than one valid keyless access transmitter is
detected upon opening the driver’s door, the driver
preferences for the lowest driver number will be recalled.
Certain features can be programmed not to recall until
the ignition is turned off.
The default settings for the personalization features
were set when your vehicle left the factory, but
may have changed from their default state since then.
