Stop towing every 200 miles (300 km) and start the
engine. Leave the transfer case shift lever in NEUTRAL.
Shift your automatic transmission to DRIVE (D);
leave a manual transmission in SECOND (2) with the
clutch engaged. Run the engine at 2,000 rpm for
one minute to circulate oil in the transfer case. Turn the
ignition key to ACC. Now, you can continue towing
your vehicle.
Notice:Locking the steering column when towing
your vehicle may damage the steering column.
Always unlock the steering column before towing.
Notice:If you exceed 55 mph (90 km/h) while
towing your vehicle, it could be damaged. Never
exceed 55 mph (90 km/h) while towing your vehicle.
{CAUTION:
Shifting a four-wheel-drive vehicle's transfer
case into NEUTRAL can cause your vehicle to
roll even if the transmission is in Park (P) for
an automatic transmission, or if your vehicle is
in gear, for a manual transmission. You or
others could be injured. Make sure the parking
brake is ®rmly set before you shift the transfer
case to NEUTRAL.

How to Add Fluid
Here's how to add ¯uid. Refer to the Maintenance
Schedule to determine what kind of ¯uid to use. See
Part D: Recommended Fluids and Lubricants on
page 6-30.
1. Remove the ®ller plug.
2. Remove the drain plug, drain the ¯uid and reinstall
the drain plug.
3. Add ¯uid at the ®ller plug hole. Add only enough
¯uid to bring the ¯uid level up to the bottom of the
®ller plug hole.
4. Reinstall the ®ller plug. Be sure the plug is fully
seated.
Hydraulic Clutch
It is not necessary to regularly check clutch ¯uid unless
you suspect there is a leak in the system. Adding
¯uid won't correct a leak.
A ¯uid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule to determine how
often you should check the ¯uid level in your clutch
master cylinder reservoir and for the proper ¯uid.
See
Part B: Owner Checks and Services on page 6-24andPart D: Recommended Fluids and Lubricants
on page 6-30.
How to Check and Add Fluid
You do not need to check the ¯uid level unless you
suspect a clutch problem. To check the ¯uid level,
look at the markings on the reservoir. If the ¯uid reaches
the MAX line, the ¯uid level is correct.

Starter Switch Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. See
Parking Brake on page 2-27if necessary.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. On automatic transmission vehicles, try to start the
engine in each gear. The starter should work only
in PARK (P) or NEUTRAL (N). If the starter works in
any other position, your vehicle needs service.
On manual transmission vehicles, put the shift lever
in NEUTRAL (N), push the clutch down halfway and
try to start the engine. The starter should work only
when the clutch is pushed down all the way to the
¯oor. If the starter works when the clutch isn't pushed
all the way down, your vehicle needs service.
Automatic Transmission Shift Lock
Control System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. See
Parking Brake
on page 2-27if necessary.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the key to the ON position,
but don't start the engine. Without applying the
regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), your vehicle needs service.
