To block out glare, you can swing down the visors. You
can also swing them from side to side. Your visors may
have an extension that can be pulled out for additional

Lighted mirrors also have an intensity switch to make
the mirror lamps brighter or dimmer.
Accessory Power Outlets
You can plug auxiliary electrical equipment into
accessory power outlets. Just pull up from the bottom
of the door and follow the proper installation
instructions that are included with any electrical
equipment that you install.
Two accessory power outlets are located on the

Another accessory power outlet is located on the
driver's side behind the third row seating position, near
the floor.
These circuits are protected by a fuse and have
maximum current levels.
NOTICE:
When using the accessory power outlets,
maximum electrical load must not exceed
25 amps. Always turn off any electrical
equipment when not in use. Leaving electrical
equipment on for extended periods will drain
your battery.

When using a scrubbing action, non-abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a cut tape detection feature
and a cleaning cassette may appear as a broken tape. To

following steps.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape Player:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio on.
3. Insert the scrubbing action cleaning cassette.
4. Within five seconds, press and hold the REV and
FWD buttons at the same time for three seconds. The
tape symbol on the display will flash, showing that
the cut tape detection feature is no longer active.

-FM Stereo with
Cassette Tape Player and Automatic Tone Control:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.
3. Press and hold the TAPE AUX button for five
seconds. The tape symbol on the display will flash
for two seconds.

5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
When the cleaning cassette has been ejected, the cut tape
detection feature is active again.
You may also choose a non

cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own. A non
-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use of a non
-scrubbing action, dry-type cleaning
cassette is not recommended.

4-39 Trailer Wiring Harness
If you have the optional trailering package, your vehicle
will have an eight
-wire harness, including the center
high
-mounted stoplamp battery feed wire. The harness
is stored on the passenger's side of the vehicle near the
rear wheel well. This harness has a 30 amp battery feed
wire and no connector, and should be wired by a
qualified electrical technician. After choosing an
aftermarket trailer mating connector pair, have the
technician attach one connector to the eight
-wire trailer
harness and the other connector to the wiring harness on
the trailer. Be sure the wiring harness on the trailer is
taped or strapped to the trailer's frame rail and leave it
loose enough so the wiring doesn't bend or break, but
not so loose that it drags on the ground. The eight
-wire
harness must be routed out of your vehicle between the
rear door and the floor, with enough of the harness left
on both sides so that the trailer or the body won't pull it.
If you do not have the optional trailering package, your
vehicle will still have a trailering harness. The harness is
located near the passenger's side rear wheel well. It
consists of six wires that may be used by after
-market
trailer hitch installers. The technician can use the
following color code chart when connecting the wiring
harness to your trailer.
Brown: Rear lamps.

Yellow: Left stoplamp and turn signal.

Dark Green: Right stoplamp and turn signal.

White (Heavy Gage): Ground.

Light Green: Back
-up lamps.

White (Light Gage): Center High
-Mounted
Stoplamp.

Blue: Auxiliary circuit (eight
-wire harness only).

Orange: Fused auxiliary (eight
-wire harness only).
Store the harness in its original place. Wrap the
harness together and tie it neatly so it won't
be damaged.
