To replace the battery:
1. Separate the transmitter with a at, thin object
inserted into the notch, located above the
metal base.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing up.
Replace with a CR2032 or equivalent battery.
4. Reassemble the transmitter.
Remote Vehicle Start
The remote vehicle starting feature allows you to start
the engine from outside of the vehicle. It also starts
up the vehicle’s automatic climate control system.
When the remote start system is active, the climate
control system will heat and cool the inside of the
vehicle according to the previous settings of the
system before turning the vehicle 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 will also turn on when it is cold outside.
SeeHeated and Cooled Seats on page 1-5for additional
information. Cooled seats are not activated during a
remote start. Normal operation of the climate control
system will return after the key is turned to ON/RUN.
SeeDual Climate Control System on page 3-40.
Laws in some communities may restrict the use of
remote starters. For example, some 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.
2-7

If your vehicle has the remote start feature, the RKE
transmitter functions will have an increased range
of operation. However, the range may be less while the
vehicle is running.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System Operation on page 2-5for
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. Pressing
the remote start button again after the vehicle
has started will turn off the ignition.
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.
After entering the vehicle during a remote start, insert
and turn the key to ON/RUN to drive the vehicle.
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:
Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The remote vehicle start feature provides two separate
starts, each with 10 minutes of engine running, or it

may be extended 10 more minutes. If you press and
release the transmitter lock button and then press and
hold the remote start button on the RKE transmitter
2-8

again before the rst 10 minutes of engine running time
has expired, 10 minutes are added to the remaining
minutes. For example, if the lock button and then
the remote start buttons are pressed again after
ve minutes of the engine run time, 10 minutes are
added and you now have 15 minutes of engine running.
The added ten minutes are considered a second
remote vehicle start.
Once two remote starts or a single start with a time
extension have been used, the vehicle must be started
with the ignition key before you can use the remote
start feature again.
The remote vehicle start feature will not operate if the
key is in the ignition, the hood is not closed, or if there is
an emission control system malfunction.
The engine will turn off during a remote vehicle start if
the coolant temperature gets too high, or the oil pressure
is too low.Your vehicle was shipped from the factory with the
remote vehicle start system enabled. The system
may be disabled through the Driver Information
Center (DIC). See “REMOTE START” underDIC
Vehicle Customization on page 3-86for additional
information.
SeeEngine Exhaust on page 2-36for important safety
information when using remote start in a closed
garage.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature.
This feature allows your dealer/retailer to add the
manufacturer’s remote vehicle start feature. See your
dealer/retailer if you would like to add the manufacturer’s

Trunk
{CAUTION:
Exhaust gases can enter the vehicle if it is driven
with the liftgate, trunk/hatch open, or with any
objects that pass through the seal between the
body and the trunk/hatch or liftgate. Engine
exhaust contains Carbon Monoxide (CO) which
cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle must be driven with the liftgate, or
trunk/hatch open:
Close all of the windows.
Fully open the air outlets on or under the
instrument panel.
Adjust the Climate Control system to a setting
that brings in only outside air and set the fan
speed to the highest setting. See Climate
Control System in the Index.
If the vehicle is equipped with a power liftgate,
disable the power liftgate function.
For more information about carbon monoxide,
seeEngine Exhaust on page 2-36.
Remote Trunk Release
G
(Remote Trunk Release):The remote trunk
release button is located to the left of the steering
wheel next to the instrument panel brightness control.
Press the button to open the trunk. The vehicle must be
in P (Park) or N (Neutral) and the valet lockout switch
must be off to use this button.
You can also press the button with the trunk symbol on
the RKE transmitter to open the trunk. To disable
this feature, seeValet Lockout Switch on page 2-20.
The trunk can be accessed using the Rear Seat
Pass-Through. See “Rear Seat Pass-Through” following
this section.

PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent system.
PASS-Key
®III+ is a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
The system is automatically disarmed when the key is
turned to ON/RUN, ACC/ACCESSORY or START
from the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.If the engine does not start and the security light comes
on when trying to start the vehicle, there may be a
problem with your theft-deterrent system. Turn the
ignition off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse, seeFuses
and Circuit Breakers on page 5-95. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the rst key may be
faulty. See your dealer/retailer who can service the
PASS-Key
®III+ to have a new key made. In an
emergency, contact Roadside Assistance.
It is possible for the PASS-Key
®III+ decoder to “learn”
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle.
The following procedure is for programming additional
keys only. If all the currently programmed keys are
lost or do not operate, you must see your dealer/retailer
or a locksmith who can service PASS-Key
®III+ to
have keys made and programmed to the system.
