You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your
rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s
how to do it:
1.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK (P) yet. Then turn your wheels into the curb if
facing downhill or into traffic if facing uphill.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes
until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake and then shift to PARK
(P).
Release the regular brakes.
When You Are Ready to Leave After
Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system
and brake adjustment. Each of these is covered in this
manual, and
the Index will help you find them quickly.
If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically to see that all hitch
nuts and bolts
are tight.

When you decide it’s safe to lift the hood, here’s what
you’ll see:
The coolant level should be at or above the
FULL
COLD mark.
A. Radiator Pressure Cap
B. Coolant Recovery Tank
C. Engine
Fan(s)
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else
until it cools down.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD mark, add a 50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
engine coolant at the coolant recovery tank. (See
“Engine Coolant’’
in the Index for more information.)
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use
a 50/50 mixture of clean water and
DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.

Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the 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 the 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.
I A CAUTION: I
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall
off, causing a serious accident.
8. Replace the wheel nuts
with the rounded end
of
the nuts toward the
wheel. Tighten each
wheel nut
by hand until
the wheel is held against
the hub.
9. Lower the vehicle by rotating the jack handle to the
left. Lower the jack completely.

10. Tighten the nuts
firmly in
a crisscross
sequence as shown.
Rotate the wheel

If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel wouldn’t be
covered by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
YOU can also write us at the following address for
advice.
Just tell us where you’re going and give your
Vehicle Identification Number
(VIN).

hinged door on the driver’s
side of your vehicle.
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.

If your vehicle has air conditioning, the auxiliary
engine fan under the hood can start up and
injure
you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
A CAUTION:
I
Things that burn can get on hot engine parts
and start
a fire. These include liquids like
gasoline or diesel fuel, oil, coolant, brake fluid,
windshield washer and other fluids, and plastic
or rubber.
You or others could be burned. Be
careful not
to drop or spill things that will burn
onto
a hot engine.
To open the hood, first
pull this handle inside the
vehicle. It is just
in front of
the driver’s side door frame
near the floor.
