Communications Commission (FCC)

Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the key is
removed from the ignition. The system is automatically
disarmed when the vehicle is
started with the correct key. The key
uses a transponder that matches an
immobilizer control unit in the
vehicle and automatically disarms
the system. Only an authorized key
starts the vehicle. The vehicle may
not start if the key is damaged.
The security light in the instrument
cluster comes on if there is a
problem with arming or disarming
the theft-deterrent system.
When trying to start the vehicle, the
security light comes 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 engine still does not start, and
the key appears to be undamaged
or the light continues to stay on, try
another ignition key. If the engine
does not start with the other key, the
vehicle needs service. If the vehicle
does start, the first key may be
damaged. See your dealer who can
service the theft-deterrent system
and have a new key made.
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.
Power Mirrors
To adjust the mirrors:
1. Move the selector switch to L (Left) or R (Right) to choose the
driver or passenger mirror.
2. Press the arrows on the control pad to move each mirror in the
desired direction.
3. Return the selector switch to the middle position.
Heated Mirrors
For vehicles with heated mirrors:
The heated outside rearview mirrors
turn on when the rear window
defogger is on and help to clear fog
or frost from the surface of the
mirrors.
1(Rear Window Defogger): This
button is on the climate control
panel.
See “Rear Window Defogger” under
Automatic Climate Control System
on page 8‑3 for more information.
Blind Spot Mirrors
The blind spot mirror is a small
convex mirror built into the upper
and outer corner of both outside
mirrors. It can show objects that
may be in the vehicle's blind zone.

Driving with the Blind Spot
Mirror
Actual Mirror View1. When the approaching vehicle is
a long distance away, the image
in the main mirror is small and
near the inboard edge of the
mirror.
2. As the vehicle gets closer, the image in the main mirror gets
larger and moves outboard.
3. As the vehicle enters the blind zone, the image transitions from
the main mirror to the blind spot
mirror.
4. When the vehicle is in the blind zone, the image only appears in
the blind spot mirror.
Using the Outside Mirror with
the Blind Spot Mirror
1. Set the main mirror so that theside of the vehicle can just be
seen and the blind spot mirror
has an unobstructed view.
2. When checking for traffic or before changing a lane, look at
the main driver/passenger side
mirror to observe traffic in the
adjacent lane, behind your vehicle. Check the blind spot
mirror for a vehicle in the blind
zone. Then, glance over your
shoulder to double check before
moving slowly into the
adjacent lane.
Park Tilt Mirrors
If the vehicle is equipped with
memory mirrors, there is an option
to have the mirrors tilt down, when
in R (Reverse), to more easily see
the ground near the vehicle.
When the vehicle is shifted to
R (Reverse), both the driver and
passenger mirrors will tilt downward.
They will return to their previous
position when the vehicle is shifted
out of R (Reverse), the ignition is
turned to OFF, or the vehicle is left
in R (Reverse) for an extended
period of time.
This feature can be turned on or off.
