Remote Vehicle Start
The remote vehicle starting feature allows you to start
the engine from outside of the vehicle. It also starts up the
vehicle’s automatic climate control system. When the
remote start system is active, the climate control system
will heat and cool the inside of the vehicle according to
the previous settings of the system before turning the
vehicle off. The rear window defogger will be turned on by
the climate control system when it is cold outside. If the
vehicle has heated seats, they will also turn on when it is
cold outside. SeeHeated and Cooled Seats on page 1-3
for additional information. Cooled seats are not activated
during a remote start. Normal operation of the climate
control system will return after the key is turned to
ON/RUN. SeeDual Climate Control System on
page 3-42.
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 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 Operation on page 2-5for
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, 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 will lock. Pressing the remote start
button again after the vehicle has started will turn off
the ignition.
When the vehicle starts, the parking lamps will 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, insert
and turn the key to ON/RUN to drive the vehicle.

If the vehicle is left running it will automatically shut off
after 10 minutes unless a time extension has been done.
To manually shut off a remote start:
Aim the RKE 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 you press and
release the transmitter lock button and then press and
hold the remote start button on the RKE transmitter 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 ignition key before you can use the remote
start feature again.The remote vehicle start feature will not operate if the
key is in the ignition, the hood is not closed, or if there is
an emission control system malfunction.
The engine will turn off during a remote vehicle start if
the coolant temperature gets too high, or the oil pressure
is too low.
Your vehicle was shipped from the factory with the
remote vehicle start system enabled. The system may
be disabled through the Driver Information Center (DIC).

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be 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. You increase the chance
of being thrown out of the vehicle in a
crash if the doors are not locked. So, wear
safety belts properly and lock the doors
whenever you drive.
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 your vehicle
whenever you leave it.
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.
Because your vehicle has the theft-deterrent system,
you must unlock the doors with the key or remote
keyless entry transmitter to avoid setting off the alarm.
From the outside, use either the key or the remote
keyless entry transmitter.
From the inside, use the power door lock switches or
manual lock knobs. The manual lock knobs are located
at the top of the door panel near the window.
Push the manual lock knob down to lock the door.
To unlock the door, pull up on the knob.
Central Door Unlocking System
Your vehicle has a central door unlocking mode. When
unlocking the driver’s door, you can unlock the other
doors at the same time by turning the key clockwise in
the door lock cylinder twice.
