Programming Transmitters to the
Vehicle
Only RKE transmitters programmed to this vehicle will
work. If a transmitter is lost or stolen, a replacement can
be purchased and programmed through your dealer.
When the replacement transmitter is programmed to
this vehicle, all remaining transmitters must also be
reprogrammed. Any lost or stolen transmitters will no
longer work once the new transmitter is programmed.
The vehicle can have a maximum of eight transmitters
programmed to it. See “Relearn Remote Key” under
DIC Operation and Displays (With DIC Buttons)
on
page 4‑47or DIC Operation and Displays (Without DIC
Buttons)on page 4‑55for instructions on how to
program RKE transmitters to the vehicle.
Battery Replacement
Replace the battery if the REPLACE BATTERY IN
REMOTE KEY message displays in the DIC. See
“REPLACE BATTERY IN REMOTE KEY” underDIC
Warnings and Messages
on page 4‑61for additional
information.
Notice: When replacing the battery, do not touch
any of the circuitry on the transmitter. Static from
your body could damage the transmitter.

Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
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
on page 3‑4for 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. The vehicle's doors will lock. Immediately press
and hold the transmitter's remote start button until
the turn signal lights flash. If you cannot see the
vehicle's lights, press and hold the remote start
button for two to four seconds. Pressing the remote
start button again after the vehicle has started will
turn the engine off. When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.
If the vehicle is left running it will automatically shut
off after 10 minutes unless a time extension has
been done.
3. If it is the first 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

For example, if the lock button and then the remote start
buttons are pressed again after the vehicle has been
running for five minutes, 10 minutes are added, allowing
the engine to run for 15 minutes.
The additional ten minutes are considered a
second remote vehicle 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 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 and the check
engine light comes on.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”
under DIC Vehicle Customization (With DIC Buttons)
on
page 4‑71for additional information. If your vehicle
does not have DIC buttons, see your dealer to enable
or disable the remote vehicle start system.

the doors are not locked. So, all passengers
should wear safety belts properly and the
doors should be locked whenever the vehicle
is driven.
.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 the vehicle whenever
leaving it.(Continued)

.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.

the key is in the ignition, all of the doors will lock and
then the front passenger's door will unlock.
Liftgate/Liftglass
{WARNING:
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.
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. See Climate Control
System
on page 4‑18or Dual Automatic
Climate Control System on page 4‑20.
(Continued)
3-12

WARNING: (Continued)
.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.
See Engine Exhaust on page 3‑50.
If your vehicle has a power liftgate, see Power Liftgate
on page 3‑14.
To unlock the liftgate, use the power door lock switch or
press the door unlock button on the Remote Keyless
Entry (RKE) transmitter twice. See Remote Keyless
Entry (RKE) System Operation

underside of the liftgate handle (B). 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 or liftglass cannot be opened if the rear
wipers are in motion. Attempting to open the liftgate or
liftglass while the rear wipers are in motion will cause
the release of the liftglass or liftgate to delay until the
wipers are moved off the liftglass.
3-13

If you shift the transmission out of P (Park) while the
power function is in progress, the liftgate power function
will continue to completion. If you shift the transmission
out of P (Park) and accelerate before the power liftgate
latches closed, the liftgate may reverse to the open
position. Cargo could fall out of the vehicle. Always
make sure the power liftgate is closed and latched
before you drive away.
If you power open the liftgate and the liftgate support
struts have lost pressure, the lights will flash and a
chime will sound. The liftgate will stay open temporarily,
then slowly close. See your dealer for service before
using the liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle during a power
open or close cycle, a warning chime will sound and the
liftgate will automatically reverse direction to the full
closed or open position. After removing the obstruction,
the power liftgate operation can be used again. If the
liftgate encounters multiple obstacles on the same
power cycle, the power function will deactivate, and
you must manually open or close the liftgate. The
REAR ACCESS OPEN warning message in the Driver
Information Center (DIC) will indicate that the liftgate is
open. After removing the obstructions, manually open
the liftgate to the full open position or close the liftgate
to the fully closed and latched position. The liftgate will
now resume normal power operation.Your vehicle has pinch sensors located on the side
edges of the liftgate. If an object is caught between the
liftgate and the body and presses against this sensor,
the liftgate will reverse direction and open fully. The
liftgate will remain open until it is activated again or
closed manually. Do not force the liftgate open or closed
during a power cycle.
Manual Operation of Power Liftgate
To change the liftgate to manual operation, press the
switch on the overhead console to the OFF position.
With the power liftgate disabled and all of the doors
unlocked, the liftgate can be manually opened and
closed.
To open the liftgate, press the touchpad on the handle
on the outside of the liftgate, and lift the gate open. To
close the liftgate, use the pull cup to lower the liftgate
and close. The liftgate latch will power close. Always
close the liftgate before driving.
If the RKE button or the power close button on the
liftgate is pressed while power operation is disabled, the
lights will flash three times, but the liftgate will not move.
It is not recommended that you drive with the liftgate
open, however, if you must drive with the liftgate open,
the liftgate should be set to manual operation by
pressing the OFF switch on the center console.
