3. Slide the delay slide knob to the
center of travel. The further you
move the knob to the right, the
longer the headlamps stay on after
the ignition is turned to the OFF
position. The autolamp will keep
the headlamps on for a maximum
of three minutes after the ignition
is turned off.
4. The autolamp automatically
turns the lamps on and off.
Automatic dimming feature
The autolamp/automatic dimming
mirror is equipped with an
automatic dimming feature. This
feature will change from the
normal state to the non-glare
``active'' state when bright lights
(glare) reach the mirror. When the
mirror detects bright light from the
front or behind, it will adjust
automatically to minimize glare.
The automatic dimming feature is
active when the ignition is turned
to the ON position.
When active, the mirror senses
bright light (glare) from the front
and rear and automatically adjusts
itself to minimize glare.

on downgrades. Transmission
operates in gears 1-2.
1 - LowUse 1 (Low) to provide
maximum engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
D(Overdrive). Selecting 1 (Low)
at higher speeds causes a shift to 2
(Second), and will shift to 1 (Low)
after vehicle decelerates to the
proper speed.
Brake-shift interlock
This vehicle is equipped with a
brake-shift interlock feature that
prevents the gearshift from being
moved from P unless the brake
pedal is depressed.
If you cannot move the gearshift
out of P with the brake pedal
depressed:
1. Apply the parking brake.
2. Turn ignition key to LOCK, then
remove the key.
3. Insert the key and turn to OFF.
4. Apply brake pedal and shift to N
(Neutral).
5. Start the vehicle.
If it is necessary to use the above
procedure to move the gearshift, it
is possible that a fuse has blown
and the vehicle's brakelamps may
not be operating properly. Refer to
Fuses and relaysin theRoadside
emergencieschapter.

FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse
may have blown. Blown fuses are
identified by a broken wire. Check
the appropriate fuses before
replacing any electrical
components.
Always replace a fuse with
one that has the specified
amperage rating. Using a fuse
with a higher amperage rating
can cause severe wire damage
and could start a fire.
