15. CHECK STEERING WHEEL FOR
EXCESSIVE PLAY.
A. With the front tires straight ahead,
turn the steering wheel until motion is
observed at the front wheels.
B. Align a reference mark on the ruler,
and then slowly turn the steering
wheel in the opposite direction until
motion is again detected at the wheels.
C. Measure the lash (free-play) at the
rim of the steering wheel. (Refer to the
OEM Operator’s Manuals.)
D. Excessive lash exists if steering
wheel movement exceeds 4 - 3⁄4 inch
(121mm) with an 18 inch (470 mm)
steering wheel. If there is excessive
lash, check the steering system for
wear or incorrect adjustment of the
linkage and steering gear before
operating the vehicle.
16. CHECK ENGINE OIL PRESSURE
WARNING SYSTEM.
A. When the engine is started, the oil
pressure warning will come “On” until
the oil pressure rises above a preset
minimum.
B. If the warning system does not come
on when the ignition is turned “On”,
repair the system.
17. MAKE SURE THE ELECTRIC
HORN IS OPERATING PROPERLY.
18. CHECK WINDSHIELD WIPER
OPERATION, INCLUDING FLUID
LEVEL.
19. CHECK THE OPERATION OF
THE BACKUP ALARM.
Make sure the backup alarm (if
equipped) is operating properly.
20. INSPECT EXTERIOR LIGHTING.
Turn “On” the headlights; inspect both
high and low beams. Inspect turn, stop,
backup, and side marker and clearance
lights; replace if not working.
21. INSPECT INTERIOR LIGHTING.
If any of the instrument panel gauge
bulbs, the dome lights, step-well
light, reading lights, rear luggage
compartment light (if equipped) or
the right/left hand turn indicator light
bulbs are not working, replace them.
22. INSPECT THE TIRES.
A. Check tire pressure and inspect
each tire for bulges, cracks, cuts
or punctures. The load and cold
inflation pressure must not exceed
the rim or wheel manufacturer’s
recommendations, even though the
tire may be approved for a higher load
or inflation. Some rims and wheels are
stamped with a maximum load and
maximum cold inflation rating. If they
are not stamped, consult the rim
or wheel manufacturer for the correct
tire inflation pressure for the vehicle
load. If the load exceeds the maximum
rim or wheel capacity, the load must be
adjusted or reduced.
B. Check the inflation pressure of
the tires before each trip, using
an accurate tire pressure gauge.
Tires should be checked when cool.
The correct pressure for each tire
is provided on the manufacturer’s
certification label. Keep tires inflated
to the applicable pressure.
Be sure the valve stem caps are on
every tire and that they are screwed on
finger tight.
Over-inflation gives the treaded
surface of the tire a convex shape
(Refer to the OEM Operator’s Manuals
for tire figures). This causes extreme
tire wear in the middle part of the tire.
