WHAT TO DO
CAUTION: 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: 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.

WHAT SHOULD BE DONE
~ ~~~
Now and then, make sure all your belts, buckles, latch plates, retractors, anchorages and
reminder systems are working properly. Look for any loose parts or damage.
If you see anything
that might keep
a restraint system from doing its job, have it repaired.
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
Engine Exhaust in the Index.
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 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.
NOTE:
A low brake fluid level can indicate worn disc brake pads which 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 anti-lock brake system
warning light stays on or comes on, something may be wrong with the anti-lock brake system.
See the
Index under Anti-Lock Brake System Wawing Light.
