Driving and Operating 9-55
while parked, preferably on level
ground, with the transmission out of
gear and the parking brake applied,
for a few minutes before turning the
engine off. If the overheat warning
comes on, seeEngine Overheating
on page 10‑24.
Parking on Hills
{WARNING
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.

How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer service department and have
it repaired as soon as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, it should be
done at the dealer service
department. Contact your dealer for
additional information or refer to the
procedure in the service manual. To
purchase a service manual, see
Service Publications Ordering
Information on page 13‑14.Change the fluid and filter at the
intervals listed in
Scheduled
Maintenance
on page 11‑3, and be
sure to use the fluid listed in
Recommended Fluids and
Lubricants on page 11‑7.
Manual Transmission
Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to a dealer
for service. Have it repaired as soon
as possible. You may also have the
fluid level checked by your dealer
when the oil is changed. See
Recommended Fluids and
Lubricants
on page 11‑7for the
proper fluid to use.
Hydraulic Clutch
It is not necessary to regularly
check clutch fluid unless you
suspect there is a leak in the
system. Adding fluid will not correct
a leak. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
When to Check and What
to Use
The hydraulic clutch fluid reservoir
cap has this symbol on it. See
Engine Compartment Overview
on
page 10‑6for reservoir location.

10-32 Vehicle Care
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
If the level is below the bottom of
the filler plug hole, located on the
rear axle, you'll need to add some
lubricant. Add enough lubricant to
raise the level to the bottom of the
filler plug hole.
What to Use
Refer to the Maintenance Schedule
to determine what kind of lubricant
to use. SeeRecommended Fluids
and Lubricants on page 11‑7.
Starter Switch Check
{WARNING
When you are doing this
inspection, the vehicle could
move suddenly. If the vehicle
moves, you or others could be
injured.
1. Before starting this check, be sure there is enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular brake.
See Parking Brake (Manual)
on
page 9‑33or Parking Brake
(Electric) on page 9‑34. Do not use the accelerator
pedal, and be ready to turn off
the engine immediately if it
starts.
3. For automatic transmission vehicles, try to start the engine
in each gear. The vehicle should
start only in P (Park) or
N (Neutral). If the vehicle starts
in any other position, contact
your dealer for service.
For manual transmission
vehicles, put the shift lever in
Neutral, push the clutch pedal
down halfway, and try to start
the engine. The vehicle should
start only when the clutch pedal
is pushed down all the way to
the floor. If the vehicle starts
when the clutch pedal is not
pushed all the way down,
contact your dealer for service.

however, urge that all
recommended maintenance
services be performed at the
indicated intervals and the
maintenance be recorded.

.All‐wheel‐drive vehicles only:
Transfer case fluid change
(severe service) for vehicles
mainly driven in heavy city traffic
in hot weather, in hilly or
mountainous terrain, when
frequently towing a trailer,
or used for taxi, police,
