Remote Vehicle Start
This vehicle may have a remote
starting feature that starts the
engine from outside of the vehicle.
/(Remote Start): This button is
located on the RKE transmitter if the
vehicle has remote start.
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 the vehicle is low on fuel. The
vehicle could run out of fuel.
If the 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, see
Remote Keyless
Entry (RKE) System
on page 2‑2for additional information.
Starting the Engine Using
Remote Start
To start the vehicle:
1. Aim the RKE transmitter at the vehicle.
2. Press
Qon the RKE transmitter.
3. Immediately after completing Step 2, press and hold
/until
the parking lamps flash. If the
vehicle's lights can not be seen,
press and hold
/for at least
four seconds.
When the vehicle starts the parking
lamps will turn on and remain on as
long as the engine is running. The
doors will be locked and the climate
control system will operate
automatically if the vehicle has the automatic system, or at the same
setting as when the vehicle was last
turned off.
If the vehicle has an automatic
climate control system and heated
seats, the heated seats turn on
during colder outside temperatures
and shut off when the key is turned
to ON/RUN. See
Heated Front
Seats
on page 3‑8or Heated and
Ventilated Front Seatson
page 3‑9for more information.
The rear window defogger and
heated mirrors, if the vehicle has
them, turn on during colder outside
temperatures and turn off when the
key is turned to ON/RUN.
After entering the vehicle during a
remote start, insert and turn the key
to the ON/RUN position to drive the
vehicle.
If the vehicle is left running it
automatically shuts off after
10 minutes unless a time extension
has been done.

Extending Engine Run Time
To extend the engine run time by
10 minutes, repeat Steps 1 though 3
while the engine is still running. The
engine run time can only be
extended if it is the first remote start
since the vehicle has been driven.
Remote start can be extended
one time.
If the remote start procedure is
used again before the first
10 minute time frame has ended,
the first 10 minutes will immediately
expire and the second 10 minute
time frame will start.
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 a total of
15 minutes.A maximum of two remote starts or
remote start attempts are allowed
between ignition cycles.
After the vehicle's engine has been
started two times using the remote
start button, the ignition must be
turned on and then back off before
the remote start procedure can be
used again.

vehicle and press
/until the
parking lamps turn off.

then off.
Conditions in Which the
Remote Start Will Not Work
The vehicle cannot be started using
the remote start feature if the key is
in the ignition, the hood is open, or if
there is an emission control system
malfunction.
The engine turns 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 the vehicle has
DIC buttons. See “REMOTE
START” underVehicle
Personalization (With DIC Buttons)
on page 5‑44for additional

This 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 comes on if there
is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key
®III+ system
senses an incorrect key, the vehicle
does not start. 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 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 and check
the fuses. See
Fuses and Circuit
Breakers
on page 10‑31for
additional information. If the engine
still does not start with the other key,
the vehicle needs service. If the
vehicle does start, the first 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. See Roadside
Assistance Program on page 13‑5.
It is possible for the PASS-Key
®III+
decoder to learn the transponder
value of a new or replacement key.

3-8 Seats and Restraints
Heated Front Seats
{WARNING
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns
even at low temperatures. To
reduce the risk of burns, people
with such a condition should use
care when using the seat heater,
especially for long periods of
time. Do not place anything on
the seat that insulates against
heat, such as a blanket, cushion,
cover or similar item. This may
cause the seat heater to
overheat. An overheated seat
heater may cause a burn or may
damage the seat.On vehicles with heated front seats,
the controls are located on the

{WARNING
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the right front
passenger airbag..Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for your vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy
on
page 13‑14and Event Data
Recorders on page 13‑15.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer/retailer
for service.
