WHAT TO DO
While parked, and with the parking brake set, try to turn the key to Lock in each shift lever
position.
The key should turn to Lock only when the shift lever is in P (Park).
The key should come out only in
Lock.
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 fool
un the regula1
brake, set the parking brake.
To check the parking brake: With the engine running and transaxle in N (Neutral), slowly
remove foot pressure from the regular brake pedal.
Do this until the vehicle is held by the
parking brake only.
To check the P (Park) mechanism’s holding ability: Shift to P (Park). Then release all brakes.
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. 1 301

Inspection
WHAT SHOULD BE DONE
Inspect the front and rear suspension and steering system for damaged, loose or missing parts,
signs of wear, or lack of lubrication. Inspect the power steering lines and hoses for proper
hookup, binding, leaks, cracks, chafing, etc. Clean and then inspect the drive axle boot seals for
damage, tears or leakage. Replace seals if necessary.
Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken,
damaged, missing or out-of-position parts as well as open seams, holes, loose connections, or
other conditions which could cause a heat build-up in the floor
pan or could let exhaust fumes
into the vehicle. See the
Index under Engine Ekhaust.
Inspect the throttle linkage for interference or binding, and for damaged or missing parts.
Replace parts as needed.
Inspect the complete system. Inspect brake lines and hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect
other brake parts, including 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.
NOTE: A low brake fluid level can indicate worn disc brake pads whi\
ch may need to be
serviced. Also, if the brake system warning light stays on or comes on, something may be wrong
with the brake system. See the
Index under Brake System Warning Light. If your vehicle is
equipped with anti-lock brakes and the anti-lock brake system w\
arning light stays on, comes on
or flashes, something may be wrong with the anti-lock brake system. See the
Index under Anti-
Lock Brake System Warning Light.
