Premaintenance
Procedures
Maintaining the Vehicle under
Special Operating Conditions
If the vehicle is subjected to any of the conditions
listed below, maintenance should be performed twice
as frequently.
•
Desert operation
•
Cold climate operation (below 50° F [10° C])
•
Trailer towing
•
Driving time typically less than 5 minutes
•
Frequent operation in dusty conditions
•
Construction work
•
After extended operation in mud, sand, water, or
similar dirty conditions, have your brakes inspected
and cleaned as soon as possible. This will prevent
any abrasive material from causing excessive wear.
•
Under frequent heavy duty operating conditions,
lubricate all grease fittings and inspect air cleaner
daily to prevent excessive wear.
Jacking the Vehicle
Whenever the engine is run for routine maintenance
and/or engine diagnostics, the rear wheels of the vehicle
should be 1 inch (25 mm) off the ground with the rear
axle supported on jack stands.
The vehicle may be unstable when using a
jack. It could slip off the jack, injuring anyone
beneath it.
•
Do not start the engine while the vehicle is
on a jack.
•
Always remove the key from the ignition
before getting off of the vehicle.
•
Block the tires when the vehicle is on a jack.
The jacking point at the front of the vehicle is on the
front of the frame behind the towing tongue (Figure 29)
The jacking point at the rear of the vehicle is under the
axle tubes (Figure 30).
