Hydroplaning
Hydroplaning is dangerous. Water
can build up under your vehicle’s
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When your vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is
to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
•Allow extra following distance.
•Pass with caution.
•Keep windshield wiping
equipment in good shape.
•Keep the windshield washer fluid
reservoir filled.
•Have good tires with proper tread
depth. SeeTires on page 9-43 .
•Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving.
If you become tired or sleepy, find
a safe place to park your vehicle
and rest.
Other driving tips include:
•Keep the vehicle well ventilated.
•Keep interior temperature cool.
•Keep your eyes moving — scan
the road ahead and to the sides.
•Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
•Keep the vehicle serviced
and in good shape.
•Check all fluid levels and brakes,
tires, cooling system, and
transmission.
•Going down steep or long hills,
shift to a lower gear.
{CAUTION
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.
8-8 Driving and Operating
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 flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet for vehicles
with an automatic transmission,
or into gear for vehicles with a
manual transmission. 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 brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park) for vehicles
with an automatic transmission
or into gear for vehicles with
a manual transmission.
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, and
•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 this
manual’s Maintenance Schedule or
Index for more information. Things
that are especially important in trailer
operation are automatic transmission
fluid, 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. See Engine Overheating
on page 9-23.

Cooling System
When it is safe lift the hood:
A. Electric Engine Cooling Fans
B. Pressure Cap
C. Engine Coolant Recovery Tank{CAUTION
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
{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 fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
Engine Coolant
The coolant in the vehicle should
last for five years or 150,000 miles
(240 000 km), whichever occurs
first. When coolant is added
or changed, use DEX-COOL
®
coolant.
The following explains the cooling
system and how to add coolant
when it is low. If there is a problem
with engine overheating, see
Engine Overheating on page 9-23.
Vehicle Care 9-19
What to Use
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL®
coolant, which will not damage
aluminum parts. If this coolant
mixture is used, nothing else
needs to be added.
{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 would not get the
overheat warning. The engine
could catch fire 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.
•Gives freezing protection down to
−34°F (− 38°C).
•Gives boiling protection up to
265°F (129°C).
•Protects against rust and
corrosion.
•Helps keep the proper engine
temperature.
•Lets 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 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 your vehicle.
Checking Coolant
The vehicle must be on a level
surface. When the engine is cold,
the coolant level should be at LOW,
or a little higher. When the engine
is warm, the level should be up to
FULL, or a little higher. If it is not,
there could be a leak at the pressure
cap or in the radiator hoses, heater
hoses, radiator, water pump, or
somewhere else in the cooling
system.
See
Engine Compartment Overview
on page 9-6 for the location of
the coolant recovery tank.
9-20 Vehicle Care
How to Add Coolant to the
Coolant Recovery Tank
If you need more coolant, add the
proper DEX-COOL®coolant mixture
at the coolant recovery tank, but
be careful not to spill it.
Occasionally check the coolant level
in the radiator. For information on
how to add coolant to the radiator,
see Cooling System on page 9-19 .
{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.
{CAUTION
Adding only plain water to your
cooling system can be dangerous.
Plain water, or some other liquid
such as alcohol, can boil before
the proper coolant mixture will.
(Continued)
CAUTION (Continued)
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 would
not get the overheat warning.
Your engine could catch fire and
you or others could be burned.
Use a 50/50 mixture of clean,
drinkable water and a proper
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.
Vehicle Care 9-21
How to Add Coolant to the
Radiator
When the coolant in the coolant
recovery tank is at the FULL mark,
start the vehicle.
If the overheat warning continues,
there is one more thing that can
be done. Add the proper coolant
mixture directly to the radiator but
be sure the cooling system is
cool before you do it.
{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
surge tank pressure cap — even a
little — they can come out at high
speed. Never turn the cap when
the cooling system, including the
surge tank pressure cap, is hot.
Wait for the cooling system and(Continued)
CAUTION (Continued)
surge tank pressure cap to cool
if you ever have to turn the
pressure cap.
{CAUTION
Turning the radiator pressure cap
when the engine and radiator are
hot can allow steam and scalding
liquids to blow out and burn you
badly. With the coolant recovery
tank, you will almost never have
to add coolant at the radiator.
Never turn the radiator pressure
cap — even a little — when the
engine and radiator are hot.
1. Remove the pressure cap when the cooling system, including the
pressure cap and upper radiator
hose, is no longer hot. Turn
the pressure cap slowly
counterclockwise until it first
stops. Do not press down while
turning the pressure cap. If you hear a hiss, wait for that to
stop. A hiss means there is
still some pressure left.
2. Keep turning the pressure cap, but now push down while turning.
Remove the pressure cap.
3. Fill the radiator with the proper coolant mixture, up to the base
of the filler neck. For more
information about the proper
coolant mixture look earlier in
this section.
4. Then fill the coolant recovery tank to the FULL mark.
