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 3-56for additional information.
A weak battery may also cause the DIC to display
Electronic Key Not 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 ignition control knob. See
Starting the Engine on page 2-35, for additional
information about your vehicle’s electronic keyless
ignition with push 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, do not touch
any of the circuitry on the transmitter. Static
from your body could damage the transmitter.To replace the battery:
1. Separate the halves of the transmitter with a at,
thin object inserted into the slot on the side or
back of the transmitter.

Remote Vehicle Start
This vehicle may have a remote starting feature that
starts the engine from outside of the vehicle. It may also
start the vehicle’s automatic climate control system.
When the remote start system is active, the climate
control system heats and cools the inside of the vehicle
according to the previous settings of the system
before turning the vehicle off. The windshield defroster
or rear window defogger turn on if it is cold outside.
If the vehicle has heated seats, they also turn on. See
Heated and Ventilated Seats on page 1-6for additional
information. Normal operation of the climate control
system returns after the ignition is turned to ON/RUN.
SeeDual Climate Control System on page 3-24.
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 the vehicle is low
on fuel. The vehicle may run out of fuel.
If this vehicle has the remote start feature, the RKE
transmitter functions 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 2-6orKeyless Access
System on page 2-9for additional information.
/(Remote Start):Press and release the lock button
and then press and hold this button to use the remote
start feature.
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 lock. Pressing the remote start
button again after the vehicle has started turns off
the ignition.
When the vehicle starts, the parking lamps 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, press
the brake pedal and turn the ignition to ON/RUN to drive
the vehicle.
2-16

If the vehicle is left running it automatically shuts off
after 10 minutes unless a time extension has been done.
To manually shut off a remote start:
Aim the 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
provides one start with 10 minutes of engine running
that may be extended 10 more minutes. If the transmitter
lock button is pressed and released and then the remote
start button is pressed and held 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 keyless access ignition control knob before
the remote start feature can be used again.The remote start feature does not operate if any of the
following occur:
The ignition is in any position other than LOCK/OFF.
A keyless access transmitter is inside the vehicle.
The hood is open.
There is an emission control system malfunction.
The remote start feature is not enabled.
See “Remote Start” underDIC Vehicle
Customization on page 3-69.
The engine turns off during a remote vehicle start if the
coolant temperature gets too high, or the oil pressure
is too low.
This 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 3-69for additional information.

Programmable Automatic Door
Locks
If your vehicle has an automatic transmission, the
vehicle is programmed so that the doors will lock
automatically when all doors are closed, the ignition
is on, and the shift lever is moved out of PARK (P).
The doors will automatically unlock when you stop the
vehicle and move the shift lever back into PARK (P).
If your vehicle has a manual transmission, the vehicle is
programmed so that the doors will lock automatically after
the vehicle speed reaches 5 mph (8 km). The doors will
automatically unlock when the ignition is turned off and
the key is removed from the ignition.
If someone needs to exit the vehicle once the doors
are locked, have that person use the manual lever
or power door lock switch. When the door is closed
again, it will not lock automatically. Use the manual
lever or the power door lock switch to lock the door.
The power door locks can be programmed through
prompts displayed on the Driver Information
Center (DIC). These prompts allow you to choose
various lock and unlock settings. For more information
on programming, seeDIC Vehicle Customization on
page 3-69.
Rear Door Security Locks
Your vehicle has rear door security locks. These
prevent passengers from opening the rear doors from
the inside.
The rear door security
locks are located on the
inside edge of each rear

the ignition when locking your vehicle.
This feature can be overridden by pressing the lock
button on the RKE transmitter or by pressing the power
lock switch a second time.
On vehicles with a Keyless Access System, the system
can be programmed to alert you when all the doors
are closed and a transmitter has been left inside of the
vehicle. SeeDIC Vehicle Customization on page 3-69
for more information.
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

{CAUTION:
Leaving children in a vehicle with the keys is
dangerous for many reasons, children or
others could be badly injured or even killed.
They could operate the power windows or
other controls or even make the vehicle move.
The windows will function and they could be
seriously injured or killed if caught in the path
of a closing window. Do not leave keys in a
vehicle with children.
When there are children in the rear seat
use the window lockout button to prevent
unintentional operation of the windows.The power window
switches are located
on the driver’s door.
