4-41 Driving with a Trailer
CAUTION:
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon monoxide
(CO) could come into your vehicle. You can't see
or smell CO. It can cause unconsciousness or
death. See ªEngine Exhaustº in the Index.
To maximize your safety when towing a trailer:

Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.

Keep the rear
-most windows closed.

If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle. Do not use
recirculation because it only recirculates
the air inside your vehicle. See ªComfort
Controlsº in the Index.
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you'll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.

NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification.
11. Don't try to put a wheel cover on the compact spare
tire. It won't fit. Store the wheel cover securely in
the rear of the vehicle until you have the flat tire
repaired or replaced.
NOTICE:
Wheel covers won't fit on your compact spare.
If you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.
Storing a Flat or Spare Tire and Tools
CAUTION:
Storing a jack, a tire or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
CAUTION:
The underbody-mounted spare tire needs to be
stored with the valve stem pointing down. If the
spare tire is stored with its valve stem pointing
upwards, its secondary latch won't work properly,
and the spare tire could loosen and suddenly fall
from your vehicle. If this happened when your
vehicle was being driven, the tire might contact
a person or another vehicle, causing injury and,
of course, damage to itself as well. Be sure the
underbody
-mounted spare tire is stored with its
valve stem pointing down.

5-34
Storing the Spare Tire and Tools
1. Lay the compact spare tire on the ground at the
rear of the vehicle. Position the compact spare tire
so that the valve stem is pointed down facing the rear
of the vehicle.
2. Lower the cable to the ground. See ªRemoving
the Spare Tire (Vehicles without the Rear
Convenience/Cargo Tray)º or ªRemoving the Spare
Tire (Vehicles with the Rear Convenience/Cargo
Tray)º in the Index.
3. Tilt the retainer downward and slip it through the
center hole of the spare tire.
Make sure the retainer is fully seated across the
underside of the wheel.
4. Attach the folding wrench to the hoist shaft.5. Turn the folding wrench clockwise to lift the
spare tire.
6. When the tire reaches the stabilizer bar, move the
tire over the bar, then continue to turn the folding
wrench clockwise to lift the spare tire.
7. When the tire is almost in the stored position,
turn the tire so that the valve stem is towards the
rear of the vehicle.
This will help when you check and maintain tire
pressure in the spare.
8. Raise the tire fully against the underside of the
vehicle. Continue turning the folding wrench until
you feel more than two clicks. This indicates that the
compact spare tire is secure and the cable is tight.
The spare tire hoist cannot be overtightened.

9. Make sure the tire is stored securely. Push, pull, and
then try to rotate or turn the tire. If the tire moves,
use the folding wrench to tighten the cable.Put back all tools as they were stored in the jack storage
compartment and put the compartment cover back on.
To put the cover back on, slip the tabs on the side of
the cover into the cover opening. Push the cover in place
and push down the tabs on the cover so that it rests
in the groove. This secures the cover in place.
When you replace the compact spare with a full
-size
tire, reinstall the bolt
-on wheel covers or the center cap
(if equipped). Tighten them ªhand tightº over the wheel
nuts, using the folding wrench.
