Battery Replacement
Under normal use, the battery in your keyless access
transmitter should last about three years.
The battery is weak if the transmitter will not work at the
normal range in any location. If you have to get close
to your vehicle before the transmitter works, it is
probably time to change the battery. The DIC may
display KEY FOB BATTERY LOW.
A weak battery may also cause the DIC to display NO
FOBS DETECTED when you try to start the vehicle.
If this happens, place the transmitter in the center
console storage area transmitter pocket with the buttons
facing to the front of the vehicle. Then, with the
vehicle in PARK (P) or NEUTRAL (N), press the brake
pedal and the start button. SeeStarting the Engine
on page 2-29, for additional information about your
vehicle’s electronic keyless ignition with push button
start. Although this will start the vehicle, it is
recommended that you replace the transmitter battery
as soon as possible.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.To replace the battery:
1. Insert a at object with a thin edge into the slot on
the side of the transmitter and separate the bottom
half from the top half.
2. Carefully pull the battery out of the transmitter.
3. Put the new battery in the transmitter, positive (+)
side down. Use a battery type CR2032 or
equivalent.
4. Reassemble the transmitter. Make sure to put it
together so water will not get inside the transmitter.
5. Test the transmitter.

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
transmitter if you have remote start.
To start the vehicle using the remote start feature:
1. Aim the remote keyless access transmitter at the
vehicle.
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:
Aim the keyless access transmitter at the vehicle
and press the remote start button until the parking
lamps turn off.
Turn on the hazard warning ashers.
Press the Acc. button (ignition switch). SeeIgnition
Positions on page 2-28.
Turn on the valet lockout switch. SeeValet Lockout
Switch on page 2-25.
When you enter the vehicle during a remote start, press
the brake pedal and press the start button on the
keyless ignition switch to transition from remote start
operation to normal vehicle operation.
2-12

Laws in some local communities may restrict the use of
remote starters. For example, laws may require a
person using 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.
The remote start feature provides two separate starts,
each with 10 minutes of engine running. If you press the
lock button and then hold the remote start button on
the keyless access transmitter again for at least
three seconds before the rst 10 minutes of engine
running time has expired, 10 minutes is added to the
remaining minutes. For example, if the remote start
is initiated again after ve minutes of the engine
run time, 10 minutes is added and you now have
15 minutes with the engine running. Once two remote
starts or 20 minutes of the engine running have
been provided, the vehicle must be started using the
keyless access with pushbutton start feature, if the
engine needs to be restarted. SeeStarting the Engine
on page 2-29for more information regarding the
keyless ignition.The remote start feature will not operate if any of the
following occur:
The check engine light is displayed. See “Check
Engine Light” underMalfunction Indicator Lamp
on page 3-68.
The valet lockout switch is on.
The keyless access transmitter is in the vehicle.
The vehicle’s hood is open.
The vehicle personalization feature is not enabled.
An unauthorized vehicle entry or a vehicle theft
was attempted.
Your keyless access transmitter, with the remote start
button, 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, seeKeyless Access
System on page 2-5.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle
will not open it. You increase the chance
of being thrown out of the vehicle in a
crash if the doors are not locked. So, wear
safety belts properly and lock the doors
whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
From the outside, press the lock or unlock button on
the keyless access transmitter. When you have
your transmitter with you, you may also unlock and
open the door by pulling the door handle. You do not
have to press the unlock button on the transmitter.
Entry occurs when the door handle is pulled and the
vehicle recognizes your transmitter. SeeVehicle
Personalization on page 2-60for information on how to
program the keyless access feature.
From the inside, use the power door lock switches
located on each front door. SeePower Door Locks on
page 2-14for more information. The rear passenger
doors have manual door lock knobs located at the top of
the door panel near the window. Push down the knob
to lock the door. Pull up the knob to unlock the door.

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.

features, we know that nothing we put on it can make it
impossible to steal.
Theft-Deterrent System
Your vehicle has a theft-deterrent alarm system.
The security light is
located on the instrument
panel cluster.
If the ignition is off and a door is open, the security light
will ash, reminding you to arm the theft-deterrent
