NOTE:
Do not use the accelerator pedal, and be ready to turn off the engine immediately if it
starts.
3. Try to start the engine in each gear. The starter should work only in P (Park) or N (Neutral).
If the starter works in any other position, your vehicle needs service.
While parked, and with the parking brake set, try to
turn the key to Lock in each shift lever

try to move the shift lever out of P (Park) with normal effort. If
the shift lever moves
out of P (Park), your vehicle’s BTSI needs service.
When you are doing this check, your vehicle could begin to move. You or others could be

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
Inspect the front and rear suspension and steering system for damaged, loose or missing pa\
rts,
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 Exhaust.
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 hooku\
p, 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 Warning Light.
