Ignition Transaxle Lock Check
While parked, and with the parking brake set, try to turn
the ignition key to
LOCK in each shift lever position.
With an automatic transmission, the key should turn
to LOCK only when the shift lever
is in PARK (P).
With a manual transmission, the key should turn to
LOCK only if you push the key in farther, while
turning it towards
LOCK.
On vehicles with a key release lever, try to turn the key
to LOCK without pressing the lever. The key should
turn to LOCK only when you press the key lever.
On all vehicles,
the key should come out only in LOCK.
Parking Brake and Automatic Transmission
PARK (P) Mechanism Check
A CA "TION:
-
When you are doing this check, your vehicle
could begin to move. You or others could be
injured and property could be damaged. Make
sure there is room in front
of your vehicle in case
it begins to roll. Be ready to apply the regular
brake at once should the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot
on the regular brake, set the
parking brake.
To check the parking brake's holding ability:
With the engine running and transmission in
NEUTRAL
(N), slowly remove foot pressure from
the regular brake pedal.
Do this until the vehicle is
held by the parking brake only.
To check the PARK (P) mechanism's holding ability:
With the engine running, shift to PARK
(P).
Then release all brakes. If your vehicle is four-wheel
drive, be sure the transfer case is not in
NEUTRAL
(N).
Underbody Flushing Service
At least every spring, use plain water to flush any
corrosive materials from the underbody. Take care
to
clean thoroughly any areas where mud and other debris
can collect.

Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damage or missing parts. Replace parts as
needed. Replace any cables that have high effort or
excessive wear.
Do not lubricate accelerator and cruise
control cables.
Rear Axle (All) and Front Axle
(Four-wheel Drive) Service
Check the gear lubricant level and add if needed. See
“Rear Axle” and “Four-wheel Drive” in
the Index. A
fluid loss may indicate a problem. Check the system(s),
and repair the system(s) if needed. Refer to “Scheduled
Maintenance Services,” earlier
in this section, to
determine when to change the lubricant.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment. You may need to have
your brakes inspected more often if your driving habits
or conditions result in frequent braking.
Clutch System Service
Check clutch pedal free travel and adjust as necessary.
See “Clutch Adjustment’’ in the Index.
