memory position again by pressing the appropriate
memory button. If the memory position is still not being
recalled, see your dealer/retailer for service.Easy Exit Seat

To replace the battery in the RKE transmitter:
1. Separate the halves of the transmitter with a at,
thin object inserted into the notch on the side.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing down.
Replace with a CR2032 or equivalent battery.
4. Put the transmitter back together tightly.
Remote Vehicle Start
Your vehicle may have a remote starting feature that
starts the engine from outside of the vehicle.
If your vehicle has an automatic climate control system,
the climate control system will default to a heating or
cooling mode depending on the outside temperatures. If
your vehicle does not have an automatic climate control
system, the system will turn on at the setting the vehicle
was set to when the vehicle was last turned off.
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 ON/RUN. SeeHeated Seats
on page 1-5for more information.
The rear window defogger and heated mirrors, if your
vehicle has them, will turn on during colder outside
temperatures and will turn off when the key is turned to
ON/RUN.
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.
2-7

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 10 minutes are considered a second
remote start.
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 started using the remote start feature again.
The vehicle cannot be started using the remote
start feature 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 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 if your vehicle has DIC
buttons. See “REMOTE START” underDIC Vehicle
Customization (With DIC Buttons) on page 3-75
for additional information. If your vehicle does not have
DIC buttons, see your dealer/retailer to enable or
disable the remote start system.
Remote Start Ready
If your vehicle does not have the remote start feature, it
will have the remote start ready feature. This feature
allows your dealer/retailer to add the manufacturer’s
remote start feature.
See your dealer/retailer if you would like to add the
manufacturer’s remote start feature to your vehicle.
2-9

Liftgate
{CAUTION:
It can be dangerous to drive with the 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.
If you must drive with the liftgate open, or if
electrical wiring or other cable connections
must pass through the seal between the body
and the 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. See Climate
Control System in the index.
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.
SeePower Liftgate on page 2-14.If your vehicle has a power liftgate, seePower Liftgate
on page 2-14.
To unlock the liftgate, use the power door lock switch or
press the door unlock button on the Remote Keyless
Entry (RKE) transmitter twice. SeeRemote Keyless
Entry (RKE) System Operation on page 2-5.
To open the liftgate, press the touchpad on the
underside of the liftgate handle. The vehicle must be in
PARK (P) to open the liftgate. To close the liftgate,
use the pull cup or pull strap as an aid.
The liftgate has an electric latch. If the battery is
disconnected or has low voltage, the liftgate will not
open. The liftgate will resume operation when the battery
is reconnected and charged.
If the battery is properly connected and has adequate
voltage, and the liftgate still will not function, your vehicle
should be taken to a dealership for service.
