If the brake system warning light
does not illuminate at this time,
seek service immediately from your authorized dealer. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your authorized dealer.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your authorized dealer. Driving extended distances with
the parking brake engaged can cause brake failure and the risk of
personal injury.

BULB REPLACEMENT
Headlamp Condensation
The headlamps are vented to equalize pressure. When moist air enters
the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.
Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America and an
“E” for Europe to ensure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.

Programming remote transmitters
It is necessary to haveall(maximum of six — original and/or new) of
your remote transmitters available prior to beginning this procedure. If
all remote entry transmitters are not present during the programming
procedure, the transmitters that are not present during programming will
no longer operate the vehicle.
To program the transmitters yourself:
Note:Ensure the brake pedal is not
depressed during this sequence.
•Unlock all doors using the power
door lock/unlock control. Insert a
key and turn the ignition from
the 1 (OFF/LOCK) to the 3 (ON)
position and cycle between 1
(OFF/LOCK) and 3 (ON) eight
times in rapid succession (within
10 seconds) with the eighth turn
ending in the 3 (ON) position. The locks will cycle to confirm that the
programming mode has been entered.
•Within 20 seconds, program a remote transmitter by pressing any
button on a transmitter. The locks will cycle once to confirm that the
remote transmitter has been programmed. (If more than 20 seconds
pass before pressing a remote transmitter button, the programming
mode will exit and the procedure will have to be repeated.)
•Repeat the previous step to program additional remote transmitters.
The locks will cycle once to confirm that each remote transmitter has
been programmed.
•When you have completed programming the remote transmitters, turn
the ignition to the 1 (OFF/LOCK) position or wait 20 seconds. Again
the doors will lock/unlock to confirm programming has been
completed.
Illuminated entry
The interior lamps illuminate when the remote entry system is used to
unlock the door(s) or sound the personal alarm, or when the factory set
5-digit code or your personal code are correctly entered into the keyless
keypad.
The illuminated entry system will turn off the interior lights if:
•the ignition switch is turned to the 3 (ON) position, or
