If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a little
too hot when you:
Climb a long hill on a hot day.
0 Stop after high speed driving.
Idle for long periods in traffic.
0 Tow a trailer.

window as necessary.
If you no
longer have the overheat warning, you can drive. Just to be safe,
drive slower for about ten minutes.
If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle right away.
If there’s still
no sign of steam, push the accelerator until the engine speed is
about twice as fast as normal idle speed. Bring the engine speed back to
normal idle speed after two or three minutes. Now see if the warning stops.

You may decide not to lift the hood but to get service help right away.

Every now and then have your dealership check your air conditioning
system to be sure it has not
lost any cooling ability. If you think the system
is not working properly, have your dealership
check it out as soon as
possible.
The air conditioning will not work when the temperature is below
40°F
(4 O C).
Lubrication
Accelerator Control System
Refer to the Maintenance Schedule to determine how often the accelerator
linkage pivot points must be lubricated and what type of lubricant
to use.
Accelerator cables and cruise control cables should not be lubricated. Any
cables that are worn or are hard to pull should be replaced.
When cleaning the engine compartment with water or steam, avoid directing
the flow onto the throttle linkage in a manner that would cau\
se moisture
to
enter the cables.
Hood Latches and Hood Hinge
Refer to the Maintenance Schedule to determine how to lubricate the hood
latch and hood hinge assembly.
Sliding Door Tracks
Your vehicle’s sliding door has three tracks which need lubrication.
For the upper and lower tracks, open the door, wipe the track\
clean and then lubricate with Lubriplate
TM White Grease.
For the outside middle track, close
the door after you finish the upper and
lower tracks. Then, wipe
the track clean and lubricate with
Lubriplate
TM White Grease.
Body
Normal use of your vehicle will cause metal to metal wear at some points on
the cab and body
if they are not lubricated.
For exposed surfaces, such as door checks, door lock bolts, lock striker
plates, dovetail bumper wedges, etc., a thin film
of engine oil should be
applied.
Where oil holes are provided in the body or cab, a dripless oil can be used.
The seat adjusters and seat track should be lubricated with chassis grease.
