Luggage Carrier (Option)
The luggage carrier has slats and side rails attached to the roof, and cross
rails which can be moved fore and aft in the side rails to help secure cargo.
Tie the load
to the side rails or side rail supports. Use the cross rails mostly
for fore and aft stops.
NOTICE:
Loading cargo that weighs more than 200 pounds (90.6 kg) on
the luggage carrier may damage your vehicle. When you carry
large things, never let them hang over the rear or the sides of
your vehicle. Load your cargo
so that it rests on the slats and
does not scratch or damage the vehicle. Put the cargo against the
side rails and fasten
it securely to the luggage carrier.
Don’t exceed the maximum vehicle capacity when loading your vehicle. For
more information on vehicle capacity and loading, see “Loading Your
Vehicle” in the Index.
To prevent damage or loss of cargo as you’re driving, check now and then to
make sure the luggage carrier and cargo are still securely fastened.
Be sure the cargo is properly loaded.
0 If small heavy objects are placed on the roof, place the load in the area
over the rear wheels (behind the rear side door
on wagon models). If
you need to, cut a piece of 3/8 inch plywood to fit inside the cross rails
and side rails to spread the load.
If plywood is used, tie it to the side rail
supports.
0 Tie the load to the cross rails or the side rail supports. Use the cross
rails only
to keep the load from sliding.

If you need to carry long items, move the cross rails as far apart as they
will go. Tie the load to the cross rails and the side rails or side rail
supports. Also tie
the load to the bumpers. Do not tie the load so tightly
that the cross rails or side rails are damaged.
After moving the cross rails, be sure to tighten all the slider screws.
Trailer Wiring Harness (Option)
An optional 7-wire
harness
is stored under
your vehicle along the
rear frame
crossmember. The
harness has a
30 amp.
in-line fused battery
feed wire and no
connector, and should
be wired by a
qualified electrical
technician.
Securely attach the harness
to the trailer, then tape or strap it to your
vehicle’s frame rail. Be sure
you leave it loose enough so the wiring won‘t
bind or break when turning with the trailer, but
not so loose that it drags on
the ground.
Store the harness in its original position. Wrap the harness together and tie it
neatly so it won’t be damaged.

Step-Bumper Pad
If your vehicle has a rear step bumper, it may be equipped with a rear step
pad at the center
of the bumper. Use this pad to improve footing when you
are stepping
on the bumper step.
If you will be using
the bumper to tow a
trailer, you must
remove the center
cutout circle to install
the trailer ball.
You
must also remove both
outer cutouts to attach
the trailer safety
chains.
To remove the pad, lift
the edge
of the pad
from the rear
of the
bumper and swing it
forward. When
the
pad releases from the
pad off.

Comfort Controls
Flow-Through Ventilation System
Your vehicle’s flow-through ventilation system supplies outside air to the
inside of your vehicle when it is moving.
I
With the side
windows closed, air
will flow into the front
I
F”
air inlet
through
and out
exhaust grilles,
the
vehicle
the rear air
valves.
Outside air will also enter the vehicle when the heater or the air
conditioning fan is running, unless your optional air conditioner is in the
MAX mode. For more information see “MAX Button” in this section.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow, or any other
obstruction
(such as leaves). The heater and defroster will work far
better, reducing the chance of fogging the inside
of your windows.
When you enter a vehicle in cold weather, turn the blower fan to HI
for a few moments before driving off. This helps clear the intake ducts
of snow and moisture, and reduces the chance of fogging the inside of
your windows.
Keep the air path under the front seats clear of objects. This helps air to
circulate throughout your vehicle.

instrument panel.
Use the handles below
your steering wheel, with the vent symbols
on them, to open and
close the vents.

When you close a vent, it will increase the flow of air coming out
of any
vents that are open.
