10 minutes, repeat Steps 1 and 2
while the engine is still running. An
extension can be requested
30 seconds after starting. 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

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
a remote start with an extension are
allowed between ignition cycles. After the vehicle's engine has been
started two times using the remote
start button or a start with an
extension, the ignition must be
turned on and then back off before
the remote start procedure can be

too high or if the oil pressure
gets low.
Door Locks
{Warning

dangerous.
. Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. When a
door is locked, the handle
will not open it. The chance
of being thrown out of the
vehicle in a crash is
increased if 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

Immobilizer Operation
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 the 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 0233 for 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 who can
service the PASS-Key III+ to have a
new key made. In an emergency,
contact Roadside Assistance. See
Roadside Assistance
Program 0308.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to eight keys may be
programmed to the vehicle. The
following procedure is for
programming additional keys only.
If all currently programmed keys are
lost or do not operate, you must see
your dealer or a locksmith who can
service PASS-Key III+ to have keys
made and programmed to the
system.

keys are to be programmed.
If the PASS-Key III+ key is lost or
damaged, see your dealer or a

The SERVICE THEFT
DETERRENT SYSTEM message
displays on the Driver Information
Center (DIC) when there is a

Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.
Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

Seats
{Warning
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns. 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

{Warning
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the
fuel system after the airbags inflate.
The feature may also activate,
without airbag inflation, after an
event that exceeds a predetermined
threshold. You can lock the doors,
turn off the interior lamps, and turn off the hazard warning flashers by
using the controls for those
features.
{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 front outboard
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 the 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 0316
and Event Data
Recorders 0316.
. Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Some warning lights come on briefly
when the engine is started to
indicate they are working. When
one of the warning lights comes on
and stays on while driving, or when
one of the gauges shows there may
be a problem, check the section that
explains what to do. Waiting to do
repairs can be costly and even
dangerous.
