If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable. See
Operating
Your
All- Wheel-Drive Vehicle Off Paved Roads on
page 4-15 for information about driving off-road.
0 Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transmission. These parts can work hard
on mountain roads.
0 Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to
a lower gear when you go
down a steep or long hill.
If you don’t shift down, your brakes could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going down a hill. You could crash. Shift down to let
your engine assist your brakes on
a steep
downhill slope. Coasting downhill in
NEU ,‘RAL (N) or with the
ignition
off is dangerous. Your brakes will have
to do
all the work of slowing down. They could
get
so hot that they wouldn’t work well. You
would then have poor braking or even none going down a
hill. You could crash. Always
have your engine running and your vehicle
in
gear when you go downhill. ~
Know how to go uphill. You may want to shift down to
a lower gear. The lower gears help cool your engine
and transmission, and you can climb the hill better.
roads in hills or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
0 As you go over the top of a hill, be alert. There could
be something in your lane, like a stalled car or an
accident.
You may see highway signs on mountains that warn
of special problems. Examples are long grades,
passing or no-passing zones, a falling rocks area or
winding roads. Be alert to these and take appropriate
action.
Stay in your own lane when driving on two-lane

Par1 . on Hills
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.
When You Are Ready to Leave After
Parking on a
Hill
1. Apply your regular brakes and hold the pedal down
while you:
But
if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet. When parking uphill, turn your wheels
away from the curb. When parking downhill, turn
your wheels into the curb.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
4. Reapply the regular brakes. Then apply your
regular brakes until
the chocks absorb the load.
parking brake, and then shift into PARK
(P).
5. Release the regular brakes.
start your 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
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 system. 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.

Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83
000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
9 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
regularly
reaches
90°F (32°C) or higher.
Uses such as found in taxi, police or delivery
If you do not use your vehicle under any of these
conditions, change the fluid and filter every
100,000 miles (1 66 000 km).
service.
How to Check
Because this operation can
be a little difficult, you may
choose
to have this done at the dealership service
department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
Notice: Too much or too little fluid can damage
your transmission.
Too much can mean that some
of the fluid could come out and fall on hot engine
part or exhaust system parts, starting
a fire.
Too little fluid could cause the transmission to
overheat.
Be sure to get an accurate reading if you
check your transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level
if you have been driving:
When outside temperatures are above
90°F (32°C).
At high speed for quite a while.
In heavy traffic-especially in hot weather
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is 180°F
to 200°F
(82°C to 93°C).
5-20

Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10OC). If it's colder than 50°F (IOOC), drive the vehicle
in
THIRD (3) until the engine temperature gage
moves and then remains steady for
10 minutes.
A cold fluid check can be made after the vehicle has
been sitting for eight hours or more with the engine
off,
but this is used only as a reference. Let the engine
run at idle for five minutes
if outside temperatures are
50°F (10°C) or more. If it's colder than 50°F (IOOC), you
may have to idle the engine longer. Should the fluid
level be low during this cold check, you
must check the
fluid hot before adding fluid. Checking the fluid hot
will give you a more accurate reading of the fluid level.
Checking the Fluid Level
Prepare your vehicle as follows:
0 Park your vehicle on a level place. Keep the engine
running.
With the parking brake applied, place the shift lever
in PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift
lever in PARK
(P).
Let the engine run at idle for three minutes or more. Then,
without shutting
off the engine, follow these steps:
-1 The automatic
transmission dipstick
handle with the
transmission and lock
symbol is located in the
engine compartment
I I on the passenger's side of
the vehicle.
See
Engine Compartment Overview on page 5-12 for
more information on location.
1. Flip the handle up and then pull out the dipstick
and wipe it with a clean rag or paper towel.
2. Push it back in all the way, wait three seconds and
then pull it back out again.
3. If the fluid level is in the acceptable range, push the
dipstick back
in all the way; then flip the handle
down to lock the dipstick in place.
5-21

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid
to use. See Part D:
Recommended Fluids and Lubricants on page 6- 17.
Add fluid only after checking the transmission fluid while
it is hot.
(A cold check is used only as a reference.) If
the fluid level is low, add only enough of the proper fluid
to bring the level up
to the HOT area for a hot check.
It doesn’t take much fluid, generally less than one
pint (0.5 L).
Don’t overfill.
Notice: We recommend you use only fluid labeled
DEXRON@
-111, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON@
-111 is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How
to Check”.
When the correct fluid level is obtained, push the
dipstick back
in all the way; then flip the handle
down
to lock the dipstick in place.
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL@ engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, 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 5-24.
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).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice: When adding coolant, it is important that
you use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@ is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the engine
coolant will require change sooner
-- at 30,000 miles
(50,000 km) or 24 months, whichever occurs first.
Damage caused by the
use of coolant other
than DEX-COOL@
is not covered by your new
vehicle warranty.
