30 Keys, Doors, and Windows
The system has one or more RKE
transmitters matched to an
immobilizer control unit in the
vehicle. Only a correctly matched
RKE transmitter will start the
vehicle. If the transmitter is ever
damaged, the vehicle may not start.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition
modes, and the RKE transmitter
appears to be undamaged, try
another transmitter. Or, try placing
the transmitter into the transmitter
pocket located in the center
console. See Starting the Vehicle
With a Low Transmitter Battery
underRemote Keyless Entry (RKE)
System Operation 08. If the ignition mode will not change
with the other transmitter or with a
transmitter in the transmitter pocket,
your vehicle needs service. If the
ignition does change modes, the
first transmitter may be faulty. See
your dealer who can service the
theft-deterrent system and have a
new RKE transmitter programmed to
the vehicle.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see Programming
Transmitters to the Vehicle under
Remote Keyless Entry (RKE)
System Operation
08.
Do not leave the transmitter 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 adjacent
lane, you could hit a vehicle that
is driving next to you. 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.

pedal applied will place the ignition
system in ACC/ACCESSORY.

This mode is for driving and starting.
With the ignition off and the brake
pedal applied, pressing the button
once will place the ignition system
in ON/RUN/START. Once engine
cranking begins, release the button.
Engine cranking will continue until
the engine starts. SeeStarting the
Engine 0238. The ignition will then
remain on.
Service Mode
This power mode is available for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. With the vehicle off and
the brake pedal not applied,
pressing and holding the button for
more than five seconds will place
the vehicle in Service Mode. The
instruments and audio systems will
operate when the vehicle is on, but
the vehicle will not be able to be
driven. The engine will not start in
Service Mode. Press the button
again to turn the vehicle off.
Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
