Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not be
covered by your vehicle’s warranty, and it could
be costly. But the notice will tell what to do to help
avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They
use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along
with the text describing the operation or
information relating to a specic component,
control, message, gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the

3. Slide the new battery into the transmitter with
the positive side of the battery facing down.
Use a type CR2032 battery, or equivalent type.
Make sure the cover is on tightly, so water will
not get in.
4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine from
outside of the vehicle. It may also start up the
vehicle’s heating or air conditioning systems and
rear window defogger. Normal operation of the
system will return after the key is turned to the RUN
position.
During a remote start, if your vehicle has an
automatic climate control system, the climate
control system will default to a heating mode during
colder outside temperatures and a cooling mode
during warmer outside temperatures. If your vehicle
does not have an automatic climate control system,
during remote start, the climate control system will
turn on at the setting the vehicle was set to when
the vehicle was last turned off.During a remote start, if your vehicle has an
automatic climate control system and heated
seats, the heated seats will turn on during colder
outside temperatures and will shut off when
the key is turned to RUN. If your vehicle does not
have an automatic climate control system,
during remote start, you will need to manually turn
the heated seats on and off. SeeHeated Seats
on page 12for additional information.
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.
The RKE 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, seeRemote
Keyless Entry (RKE) System on page 114for
additional information.

/(Remote Start):Press and release the lock
button and then press and hold the remote
start button to start the vehicle.
To start the vehicle using the remote start feature,
do the following:
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. If you cannot see
the vehicle’s lights, 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 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, do any of the
following:
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 vehicle can be remote started two separate
times between driving sequences. The engine will
run for 10 minutes after each remote start.
Or, you can extend the engine run time by another
10 minutes within the rst 10 minute remote
start time frame, and before the engine stops.
For example, if the lock button and then the remote
start buttons are pressed again after the vehicle has
been running for ve minutes, 10 minutes are
added, allowing the engine to run for 15 minutes.
The additional ten minutes are considered a
second remote vehicle start.
120

Once two remote starts, or a single remote start
with one time extension has been done, the
vehicle must be started with the key.
After the key is removed from the ignition, the
vehicle can be remote started again.
The vehicle cannot be remote started if the key is
in the ignition, the hood is not closed, or if
there is an emission control system malfunction.
Also, the engine will turn off during a remote
vehicle start if the coolant temperature gets too
high or if the oil pressure gets low.
Vehicles that have the remote vehicle start feature
are shipped from the factory with the remote
vehicle start system enabled. The system may be
enabled or disabled through the DIC. See
“REMOTE START” underDIC Vehicle
Customization (With DIC Buttons) on page 280for
additional information. If your vehicle does not
have DIC buttons, see your dealer to enable
or disable the remote vehicle start system.″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 to
add the manufacturer’s remote vehicle start
feature.
If your vehicle has the remote start ready feature,
the RKE transmitter will have an extended
range that allows locking or unlocking of the
vehicle from approximately 197 feet (60 m) away.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to your
vehicle.

If the passenger’s side power door lock switch is
pressed when the front passenger’s door is
open and the key is in the ignition, all of the doors
will lock and then the front passenger’s door
will unlock.
Liftgate/Liftglass
{CAUTION:
It can be dangerous to drive with the
liftglass or liftgate open because carbon
monoxide (CO) gas can come into your
vehicle. You cannot see or smell CO. It
can cause unconsciousness and even
death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the liftglass or
liftgate open, or if electrical wiring or
other cable connections must pass
through the seal between the body and
the liftglass or liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
with the recirculation mode off. That
will force outside air into your vehicle.
SeeClimate Control System on
page 227orDual Automatic Climate
Control System on page 231.
If you have air outlets on or under
the instrument panel, open them all
the way.
If your vehicle has a power liftgate,
disable the power liftgate function.
SeeEngine Exhaust on page 160.
If your vehicle has a power liftgate, seePower
Liftgate on page 127.

It is not recommended that you drive with the
liftgate open, however, if you must drive with the
liftgate open, the power liftgate should be switched
to manual liftgate operation — the overhead
console switch set to the “Disable” position.
Both the liftglass and liftgate have an electric latch.
If the battery is disconnected or has low voltage,
the liftglass and liftgate will not open. The
liftglass and liftgate will resume operation when
the battery is reconnected and charged.
If the battery is properly connected and has
adequate voltage, and the liftgate or liftglass still
will not function, your vehicle should be taken to a
dealership for service.

position.
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
on the instrument panel cluster comes on
when trying to start the vehicle, the key may have
a damaged transponder. Turn the ignition off
and try again.
