Recreational Vehicle Towing (Except Four-wheel Drive With
Manual Shift Transfer Case) Loading Your Vehicle
Vehicles with
two-wheel drive or the optional electronic
shift transfer case require special modifications before
they can be towed
in this manner. Please contact your
dealer for the towing information that
is appropriate for
your particular vehicle.
Vehicles
with all-wheel drive (AWD) can not be towed
in this manner.
The Certification/Tire label is found on the driver’s door
edge, above the door latch. The label shows the size
of
your original tires and the inflation pressures needed to
obtain the gross weight capacity of your vehicle. This is
called the GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight
of the vehicle, all occupants,
fuel, cargo and trailer tongue weight,
if pulling a trailer.

Return the jack, wheel wrench and wheel blocks to the
proper location in your vehicle’s rear area. Secure the

Make sure the tire and carrier are secure.
Driving with the tire or carrier unlatched could
injure pedestrians or damage the vehicle.
Compact Spare Tire (If Equipped)
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi
(420 Wa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire is correctly inflated. The compact
spare is made to perform well at speeds up to
65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size tire
repaired or replaced where
you want. Of course, it’s best
to replace your spare with a full-size tire as
soon as you
can. Your spare will last longer and be in good shape in
case you need it again.

A CAUTION:
Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause
overheating
as a result of too much friction.
You could have an air-out and a serious
accident. See “1,oading Your Vehicle” in
the Index.
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check
all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread
is badly worn, or if‘ your tires have
been damaged, replace them.
Inflation -- Tire Pressure
The Cel-tification/Tire label. which is 011 the driver‘s
door edge, above the door latch. shows the correct
inflation
pressures for your tires when they’re cold.
“Cold“ lneans your vehicle has been sitting for at least
three hours or driven no more than 1 mile ( 1 .6 km).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not.
If‘ your tires
don’t have enough air (underinflation), you can
get the following:
Too much flexing
Too much heat
0 Tire overloading
Bad wear
0 Bad handling
0 Bad fuel economy.
NOTICE: (Continued)
6-4 1

I NOTICE: (Continued) I
If your tires have too much air (overinflation),
you
can get the following:
0 Unusual wear
0 Bad handling
0 Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or n101-e. Also. check the
tire pressure
of the spare tire.
I! you have a compact spare tire. it should be at 60 psi
(420
k Pa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can't tell
if your tires are properly inflated
simply
by looking at thcm. Radial tires may look
properly inflated even when they're underintlatecl.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks
by keeping out dirt and moisture.
Tire Inspection and Rotation
Tires s11o111d be rotated every 6,000 to 8,000 miles
( IO 000 to 13 000 km). Any time you notice unusual
we;^. rotate your tires as soon as possible and check
wheel alignment.
Also check for damaged tires or
wheels. See "When 1t.s Time for New Tires" and
"Wheel Replacement" later
in this section for
more information.
Thc purpose
of' reg~~lar rotation is to achieve more
uniform wear
fur all tires on the vehicle. The first
rotation
is thu most important. See "Schecluled
Maintenance Services"
in the Index for scheduled
rotation intervals.

I1
If your vehicle has a compact spare tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
Certificatioflire label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque’’ in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come
off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle.
In an emergency, you can
use a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later, if you
need to, to get all the rust or dirt
off. (See
“Changing a Flat Tire” in the Index.)
