Part B: Owner Checks and Services
Listed below are owner checks and services which should be performed at
the intervals specified to help ensure the safety, dependability and emission
control performance of your vehicle.
Be sure any necessary repairs are completed at once. Whenever any fluids
or lubricants are added to your vehicle, make sure they are the proper ones,
as shown in Part D.
At the First 100, 1,000 and 6,000 Miles (160, I 600 and
IO 000 km)
For vehicles with dual wheels, check dual wheel nut torque. For proper
torque, see “Wheel
Nut Torque’’ in the Index.
At Each Fuel Fill
Engine Oil Level
Check the engine oil level and add the proper oil if necessary. See “Engine
Oil”
in the Index for further details.
Engine Coolant Level
Check the engine coolant level and add the proper coolant mix if necessary.
See ”Coolant”
in the Index for further details.
Windshield Washer Fluid Level
Check the windshield washer fluid level in the windshield washer tank and
add the proper fluid if necessary. See ”Windshield Washer Fluid” in the
Index for further details.
At Least Once a Month
Tire Inflation

on the Certification/Tire label which is located on the rear edge of the

Cassette Deck
Clean cassette deck. Cleaning should be done every 50 hours of tape play.
See “Audio Systems”
in the Index for further details.
At Least Once a Year
Key Lock Cylinders
Lubricate the key lock cylinders with the lubricant specified in Part D.
Body Lubrication
Lubricate all fuel doors, body hood and body door hinges, tailgate and
tailgate handle pivot points, latches, locks, and folding seat hardware. Part
D tells you what to use. More frequent lubrication may be required when
exposed to
a corrosive environment.
Starter Switch
A CAUTION:
When you are doing this check, the vehicle could move suddenly.
If it does, you or others could be injured. Follow the steps below.
1. Before you start, be sure you have enough room around the vehicle. It
should be parked
on a level surface.
2. 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.
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
floor. If the starter works when the clutch isn’t pushed all the way
down, your vehicle needs service.
