prevent another transmitter from
unlocking your vehicle. If a
transmitter is lost or stolen, a
replacement can be purchased

can also be re-coded to match
the new transmitter. Once your
dealer/retailer has coded the new
transmitter, the lost transmitter
will not unlock your vehicle.
Battery Replacement
The RKE transmitter has a lithium
battery which should last about
three years.
Have the battery replaced if the
Replace Battery in Remote
Key message displays in the DIC or
if the transmitter will not work at
the normal range in any location.
See “Replace Battery in Remote

Immobilizer Operation
Your vehicle has a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from
the ignition.
The system is disarmed when the
key is turned to ON/RUN.
You do not have to manually arm or
disarm the system.
The key uses a transponder that
matches an immobilizer control unit
in your vehicle and automatically
disarms the system. Only the correct
key will start the vehicle. If the
key is ever damaged, you may not
be able to start your vehicle.
If the vehicle does not start:
Make sure the fold away key is
fully extended.
Avoid attaching several keys with
the ignition key.
Avoid attaching keys from other
vehicles to the ignition key.
Do not attempt to start the
vehicle with a non-approved key.
Do not disassemble the key.
When trying to start the vehicle, if
the engine does not start, the
key may have a damaged
transponder. 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.
If the engine still does not start,
your vehicle needs service.
See your dealer/retailer to service
the theft-deterrent system and
have a new key made.
The following procedure is for
programming additional keys only. If
all vehicle keys are lost or no
longer work, see your dealer/retailer.
A new key must be made prior to
programming.
A maximum of four keys can be
programmed for your vehicle.The key is purchased as two
sections: the key blade and
immobilizer section (A) and the
remote keyless entry and remote
start system section (B).
Do not join the two key sections
until programming is complete.
To program a new section (A):
1. Insert the original, already
programmed key into the ignition
and start the engine.
If the engine does not start, see
your dealer/retailer.
2. Remove the key from the
ignition.

farther away than they really
are. If you cut too sharply into
the right lane, you could hit a
vehicle on your right. Check
your 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. It also makes
things, like other vehicles, look
farther away than they really are.

between the sun visors. It works
when the ignition is in ON/RUN. The
sunroof will not operate after the
engine is turned off.
From the closed position

the six open positions. The
sunshade opens with the sunroof.
Tilt the sunroof by turning the control
counter-clockwise.
Obstruction Detection
When the sunroof encounters an
obstruction while closing, it
immediately returns to the fully open
or tilt position. The sunroof will
not move again until the control is
pressed upward, or a different
