Here’s how to add fluid. Refer to the Maintenance
Schedule to determine what kind of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level up to the bottom of the
filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting.
The clutch master cylinder reservoir is
filled with hydraulic clutch fluid.
It isn’t a good idea to “top off’ your clutch fluid.
Adding fluid won’t 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
Refer to the Maintenance Schedule to determine how
often you should check the fluid level in your clutch
master cylinder reservoir and for the proper fluid. See
“Owner Checks and Services” and “Recommended
Fluids and Lubricants” in the Index.

Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system parts. If you see anything that might
keep a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas of the windshield. Also see “Wiper Blades,
Cleaning” in the Index.
Manual Transmission Check
Check the transmission fluid level; add if needed. See
“Manual Transmission” in the Index. Check for leaks.
A fluid loss may indicate a problem. Have the system
inspected and repaired if needed.
Automatic Transmission Check
Check the transmission fluid level; add if needed. See
“Automatic Transmission” in the Index. A fluid loss
may indicate a problem. Check the system and repair if
needed.
Hydraulic Clutch System Check
Check the fluid level in the clutch reservoir. See
“Hydraulic Clutch Fluid” in the Index. A fluid loss
in this system could indicate a problem. Have the
system inspected and repaired at once.
At Least Once a Year

move suddenly.
If it does, you or others could be
injured. Follow the steps below.
1.
2.
3.
Before you start, be sure you have enough room
around the vehicle.
Firmly apply both the parking brake (see “Parking
Brake”
in the Index if necessary) and the regular brake.
NOTE:
Do not use the accelerator pedal, and be
ready to turn off the engine immediately if it starts.
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 floor. If the starter works when the clutch isn’t
pushed all the way down, your vehicle needs service.
Brake-Transmission Shift Interlock (BTSI) Check
(Automatic Transmission)
When you are doing this
( !ck, the vehicle could
move suddenly.
If it does, you or others could be
injured. Follow the steps below.
1.
2.
3.
Before you start, be sure you have enough room
around the vehicle. It should be parked on
a
level surface.
Firmly apply the parking brake (see “Parking Brake”
in the Index if necessary).
NOTE: Be ready
to apply the regular brake
immediately if the vehicle begins to move.
With the engine off, turn the key to the RUN
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’s BTSI
needs service.
