Automatic Transmission Operation
There are several different positions for your shift lever.
Your vehicle features an electronic shift position
indicator within the instrument cluster. This display
must be powered anytime the shift lever is capable of
being moved out of PARK (P). This means that if your
key is in OFF, rather than LOCK, there will be a small
current drain on your battery which could discharge
your battery over a period of time. If you need to leave
your key in the ignition in OFF for an extended period
for any reason, it is recommended that you disconnect
the battery cable from the battery to prevent discharging
your battery.PARK (P): This locks your rear wheels. It's the best
position to use when you start your engine because your
vehicle can't move easily.
CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
See ªShifting Into PARK (P)º in the Index. If
you're pulling a trailer, see ªTowing a Trailerº in
the Index.

2-42 Windshield Washer
At the top of the lever,
there's a paddle with the
word PUSH on it. To spray
washer fluid on the
windshield, push the paddle.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
Washer fluid will spray as long as you push the paddle.
When you let go of the paddle, the wipers will continue
to wipe for a few seconds and then either stop or return
to the preset speed.
The use of hood
-mounted air deflectors may adversely
affect windshield wiper and washer performance.
Rear Window Wiper and Washer
The rear window
wiper/washer switch is on
your instrument panel, to
the right of the gage cluster.
To turn the wiper on, slide the switch all the way up.
For delay wiping, slide the switch even with DELAY in
the center position of the rear wiper control. The wiper
will cycle every nine seconds.

2-48 Fog Lamps
Your vehicle has fog lamps. Use them for better vision
in foggy or misty conditions. Your parking lamps and/or
low
-beam headlamps must be on for your fog lamps
to work.
The fog lamp switch is
located to the right of the
instrument panel cluster.
Press the ribbed top part of the switch to turn the fog
lamps on. Press the bottom of the switch to turn them
off. An indicator light will illuminate in the switch when
the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps in
the dark without turning on your headlamps.Fog lamps will go off whenever your high
-beam
headlamps come on. When the high
-beams are off, the
fog lamps will come on again.
Headlamp Delay
Your vehicle is equipped with a headlamp delay feature
that holds the headlamps on for a short period of time
after the ignition is turned off.
The HEADLAMP DELAY button is located on the
lower left side of the inside rearview mirror.
