(f)Lubricate all key lock cylinders, body door and fuel
door hinges, latches and locks (including glove box and
console doors), hood latch assembly, secondary
latch, pivots, spring anchor, release pawl, and any
moving seat hardware. Lubricate hood safety lever pivot
and prop rod pivot and tailgate latch bolt, handle
assembly pivot points, and hinges. More frequent
lubrication may be required when exposed to a corrosive
environment. Applying silicone grease on weatherstrips
with a clean cloth will make them last longer, seal
better, and not stick or squeak.
(g)A uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the uid level checked. Add uid if needed.
(h)Change automatic transmission uid and lter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.(i)Drain, ush, and re ll cooling system. This service
can be complex; you should have your dealer perform
this service. See Engine Coolant on page 5-25 for
what to use. Inspect hoses. Clean radiator, condenser,
pressure cap, and ller neck. Pressure test the
cooling system and pressure cap.
(j)If you drive regularly under dusty conditions, inspect
the lter at each engine oil change.
(k)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.

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. SeeParking Brake
on page 2-28.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the ignition to ON, but do
not 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), contact your GM Goodwrench
®dealer
for service.
Ignition Transmission Lock Check
While parked, and with the parking brake set, try to turn
the ignition to LOCK in each shift lever position.
With an automatic transmission, the ignition should
turn to LOCK only when the shift lever is in
PARK (P). The key should come out only in LOCK.
With a manual transmission, the key should
come out only in LOCK.
Contact your GM Goodwrench
®dealer if service is
required.
