2-13 Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to
touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.
For battery replacement, use one Duracell
battery, type
DL
-2032, or a similar type.
To replace the battery:
1. Insert a coin into the notch near the key ring. Turn
the coin counterclockwise to separate the two halves
of the transmitter.
2. Once the transmitter is separated, use a pencil eraser
to remove the old battery. Do not use a metal object.
3. Remove and replace the battery. Replace it as the
instructions inside the cover indicate.

lamps must be on for your fog lamps to work.
If your fog lamps are on when you use your
flash
-to-pass feature, the fog lamps will be disabled
while the flash
-to-pass feature is being used.

remote keyless entry transmitter, the lamps inside your
vehicle will go on. These lamps will go off after about
25 seconds, or when you start your engine. Pressing the
LOCK button on your remote keyless entry transmitter
will turn the lights immediately off.
If a door is left ajar, your interior lamps will turn off
after 10 minutes to save your battery.
Delayed Illumination
When you open the door to enter your vehicle, the
interior lamps will come on. When you close the door
with the ignition off, the interior lamps will stay on for
25 seconds or until the ignition is turned on. Please note
that locking the doors with the power door lock switch
will override the delayed illumination feature and the
lamps will turn off right away.
Theater Dimming
This feature allows for a three to five-second fade out of
the courtesy lamps instead of immediate turn off.
Exit Lighting
With this feature, the interior lamps will come on for 25
seconds after you remove the key from the ignition. This
will give you time to find the door pull handle or lock
switches as you exit the vehicle.

2-50 Power Remote Control Mirrors (Option)
A control lever on the
driver's door controls both
outside rearview mirrors.
Turn the lever counterclockwise to select the driver's
side rearview mirror, or clockwise to select the
passenger's side rearview mirror. Then push the lever in
the direction of the desired movement to adjust each
mirror so that you can see the side of the vehicle when
you are sitting in a comfortable driving position.
Convex Outside Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
CAUTION:
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 your right. Check your
inside mirror or glance over your shoulder before
changing lanes.

Fan Knob
The left knob is the fan knob and selects the force of air
you want. Turn the knob clockwise to increase fan speed
and counterclockwise to decrease fan speed. The fan will
always run unless the right control knob is turned to OFF.
The fan must be on to run the air conditioning compressor.
Temperature Knob
The center control regulates the temperature of the air
coming through the system. Turn it toward the blue area
for cooler air. Turn it toward the red area for warmer air.
Mode Knob
The right control has settings for air conditioning and
non

you to choose the direction of air delivery.
MAX: This setting provides maximum cooling with the
least amount of work. MAX recirculates much of the air
inside your vehicle so it cools quickly. The air is
directed through the instrument panel outlets.
