Things not to do when driving down
a hill:
When driving downhill, avoid turns
that take you across the incline of
the hill. A hill that is not too steep
to drive down might be too steep
to drive across. The vehicle could
roll over.
Never go downhill with the
transmission in N (Neutral), called
free-wheeling. The brakes will
have to do all the work and could
overheat and fade.
Vehicles are much more likely to
stall when going uphill, but if it
happens when going downhill:
1. Stop the vehicle by applying the
regular brakes and apply the
parking brake.
2. Shift to P (Park) and, while still
braking, restart the engine.
3. Shift back to a low gear, release
the parking brake, and drive
straight down.
4. If the engine will not start, get
out and get help.
Driving Across an Incline
An off-road trail will probably go
across the incline of a hill. To decide
whether to try to drive across the
incline, consider the following:
{CAUTION
Driving across an incline that is
too steep will make your vehicle
roll over. You could be seriously
injured or killed. If you have any
doubt about the steepness of the
incline, do not drive across it. Find
another route instead.
A hill that can be driven straight
up or down might be too steep to
drive across. When going straight
up or down a hill, the length of the
wheel base — the distance from
the front wheels to the rear
wheels — reduces the likelihood
the vehicle will tumble end over
end. But when driving across
an incline, the narrower track
width — the distance between theleft and right wheels — might not
prevent the vehicle from tilting
and rolling over. Driving across an
incline puts more weight on the
downhill wheels which could
cause a downhill slide or a
rollover.
Surface conditions can be a
problem. Loose gravel, muddy
spots, or even wet grass can
cause the tires to slip sideways,
downhill. If the vehicle slips
sideways, it can hit something
that will trip it — a rock, a rut,
etc. — and roll over.
Hidden obstacles can make the
steepness of the incline even
worse. If you drive across a rock
with the uphill wheels, or if the
downhill wheels drop into a rut or
depression, the vehicle can tilt
even more.
For these reasons, carefully consider
whether to try to drive across an
incline. Just because the trail goes
across the incline does not mean you
have to drive it. The last vehicle to try
it might have rolled over.

Repeat this until help arrives but only
when you feel really uncomfortable
from the cold. Moving about to keep
warm also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help with
the headlamps. Do this as little as
possible to save fuel.
If Your Vehicle is Stuck in
Sand, Mud, Ice, or Snow
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
SeeRocking Your Vehicle to Get It
Out on page 4-27.If the vehicle has a traction system,
it can often help to free a stuck
vehicle. Refer to the vehicle’s
traction system in the Index. If stuck
too severely for the traction system
to free the vehicle, turn the traction
system off and use the rocking
method.
{CAUTION
If you let your vehicle’s tires spin
at high speed, they can explode,
and you or others could be
injured. The vehicle can overheat,
causing an engine compartment
re or other damage. Spin the
wheels as little as possible and
avoid going above 35 mph
(55 km/h) as shown on the
speedometer.
For information about using tire
chains on the vehicle, seeTire
Chains on page 5-62.
Rocking Your Vehicle to
Get It Out
Turn the steering wheel left and right
to clear the area around the front
wheels. Turn off any traction or
stability system. Shift back and forth
between R (Reverse) and a forward
gear, or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on
the accelerator pedal when the
transmission is in gear. Slowly
spinning the wheels in the forward
and reverse directions causes a
rocking motion that could free the
vehicle. If that does not get the
vehicle out after a few tries, it might
need to be towed out. If the vehicle
does need to be towed out, see
Towing Your Vehicle on page 4-32.

Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer,
make wider turns than normal. Do
this so the trailer will not strike soft
shoulders, curbs, road signs, trees or
other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
ash whenever signaling a turn or
lane change. Properly hooked up,
the trailer lamps also ash, telling
other drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument panel ash for turns
even if the bulbs on the trailer are
burned out. For this reason you may
think other drivers are seeing thesignal when they are not. It is
important to check occasionally to be
sure the trailer bulbs are still working.
Driving on Grades
Notice:Do not tow on steep
continuous grades exceeding
6 miles (9.6 km). Extended,
higher than normal engine and
transmission temperatures may
result and damage the vehicle.
Frequent stops are very important
to allow the engine and
transmission to cool.
Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if the
transmission shifts too often under
heavy loads and/or hilly conditions.
Reduce speed and shift to a lower
gearbeforestarting down a long or
steep downgrade. If the transmission
is not shifted down, the brakes
might have to be used so much that
they would get hot and no longer
work well.On a long uphill grade, shift down
and reduce the vehicle’s speed
to around 45 mph (70 km/h)
to reduce the possibility of the
engine and the transmission
overheating.
When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at a
lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. If the overheat warning
comes on, seeEngine Overheating
on page 5-25.

Parking on Hills
{CAUTION
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a at surface.
If parking the rig on a hill:
1. Press the brake pedal, but do
not shift into P (Park) yet.
Turn the wheels into the curb if
facing downhill or into traffic
if facing uphill.
2. Have someone place chocks
under the trailer wheels.3. When the wheel chocks are
in place, release the regular
brakes until the chocks absorb
the load.
4. Reapply the brake pedal. Then
apply the parking brake and
shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal
while you:
Start the engine
Shift into a gear
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
The vehicle needs service more
often when pulling a trailer. See
Scheduled Maintenance on page 6-3
for more information. Things that
are especially important in trailer
operation are automatic transmission
uid, engine oil, axle lubricant, belts,
cooling system and brake system.
It is a good idea to inspect these
before and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. SeeEngine Overheating
on page 5-25.

The coolant level should be between
the MIN and MAX lines. If it is not,
you may have a leak at the radiator
hoses, heater hoses, radiator, water
pump, or somewhere else in the
cooling system.
{CAUTION
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine re, and you
could be burned. Get any leak
xed before you drive the vehicle.If there seems to be no leak, with
the engine on, check to see if
the electric engine cooling fan is
running. If the engine is overheating,
the fan should be running. If it is
not, your vehicle needs service.
Turn off the engine.
Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice:Using coolant other than
DEX-COOL
®can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant could require changing
sooner, at 30,000 miles
(50 000 km) or 24 months,
whichever occurs rst. Any
repairs would not be covered by
the vehicle warranty. Always use
DEX-COOL
®(silicate-free) coolant
in the vehicle.
How to Add Coolant to the
Coolant Surge Tank
Notice:This vehicle has a
specic coolant ll procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If you have not found a problem
yet, check to see if coolant is
visible in the surge tank. If coolant is
visible but the coolant level is not at
between the MIN and MAX lines, add
a 50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant at
the coolant surge tank, but be sure
the cooling system, including the
coolant surge tank pressure cap, is
cool before you do it. SeeEngine
Coolant on page 5-22for more
information.
5-20 Service and Appearance Care

{CAUTION
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn
the coolant surge tank pressure
cap — even a little — they can
come out at high speed. Never
turn the cap when the cooling
system, including the coolant
surge tank pressure cap, is hot.
Wait for the cooling system and
coolant surge tank pressure cap
to cool if you ever have to turn
the pressure cap.
{CAUTION
Adding only plain water to the
cooling system can be dangerous.
Plain water, or some other liquid
such as alcohol, can boil before
the proper coolant mixture will.
The vehicle’s coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, the engine
could get too hot but you would
not get the overheat warning. The
engine could catch re and you or
others could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant.
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.
{CAUTION
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
1. You can remove the coolant
surge tank pressure cap when
the cooling system, including the
coolant surge tank pressure cap
and upper radiator hose, is no
longer hot.
Turn the pressure cap slowly
counterclockwise about
one-quarter of a turn. If you hear
a hiss, wait for that to stop.
Service and Appearance Care 5-21

This will allow any pressure still
left to be vented out the
discharge hose.
2. Then keep turning the pressure
cap slowly, and remove it.
3. Fill the coolant surge tank with
the proper DEX-COOL
®coolant
mixture, to between the MIN
and MAX lines.4. With the coolant surge tank
pressure cap off, start the engine
and let it run until you can feel
the upper radiator hose getting
hot. Watch out for the engine
cooling fan.
By this time, the coolant level
inside the coolant surge tank may
be lower. If the level is lower, add
more of the proper DEX-COOL
®
coolant mixture to the coolant
surge tank until the level reaches
between the MIN and MAX lines.
5. Then replace the pressure cap.
Be sure the pressure cap is
hand-tight.
Check the level in the surge
tank when the cooling system
has cooled down. If the coolant is
not at the proper level, repeat
Steps 1 through 3 and reinstall the
pressure cap. If the coolant still is not
at the proper level when the system
cools down again, see your dealer/
retailer.
Engine Coolant
The cooling system in your vehicle
is lled with DEX-COOL®engine
coolant. This coolant is designed to
remain in your vehicle for ve years
or 150,000 miles (240 000 km),
whichever occurs rst, if you add
only DEX-COOL
®extended life
coolant.
The following explains your cooling
system and how to add coolant
when it is low. If you have a problem
with engine overheating, see
Engine Overheating on page 5-25.
A 50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant will:
Give freezing protection down to
−34°F (−37°C).
Give boiling protection up to
265°F (129°C).
5-22 Service and Appearance Care
ProCarManuals.com

Protect against rust and
corrosion.
Help keep the proper engine
temperature.
Let the warning lights and gages
work as they should.
Notice:Using coolant other than
DEX-COOL
®can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant may require changing
sooner, at the rst maintenance
service after each 30,000 miles
(50 000 km) or 24 months,
whichever occurs rst. Any
repairs would not be covered by
the vehicle warranty. Always
use DEX-COOL
®(silicate-free)
coolant in the vehicle.
What to Use
Use a mixture of one-half clean,
drinkable water and one-half
DEX-COOL
®coolant which will not
damage aluminum parts. If you
use this coolant mixture, you do not
need to add anything else.
{CAUTION
Adding only plain water to the
cooling system can be dangerous.
Plain water, or some other liquid
such as alcohol, can boil before
the proper coolant mixture will.
The vehicle’s coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, the engine
could get too hot but you would
not get the overheat warning. The
engine could catch re and you or
others could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant.Notice:If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and other
parts.
If you have to add coolant more
than four times a year, have
your dealer/retailer check your
cooling system.
Notice:If extra inhibitors
and/or additives are used in
the vehicle’s cooling system,
the vehicle could be damaged.
Use only the proper mixture of
the engine coolant listed in
this manual for the cooling
system. SeeRecommended

Coolant Surge Tank
Pressure Cap
Notice:If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
If you need to replace your coolant
surge tank pressure cap, see
your retailer.
Engine Overheating
There is a coolant temperature
warning light on your vehicle’s
instrument panel. SeeEngine
Coolant Temperature Warning Light
on page 3-34.
If Steam Is Coming From Your
Engine
{CAUTION
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down. Wait
until there is no sign of steam or
coolant before you open the hood.
If you keep driving when your
engine is overheated, the liquids
in it can catch re. You or others
could be badly burned. Stop your
engine if it overheats, and get out
of the vehicle until the engine
is cool.Notice:If the engine catches re
because of being driven with
no coolant, your vehicle can be
badly damaged. The costly
repairs would not be covered by
the vehicle warranty.
If No Steam Is Coming From
Your Engine
If you get an engine overheat
warning, but see or hear no steam,
the problem may not be too serious.
Sometimes the engine can get a little
too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
