SERVICE ADJUSTMENT PROCEDURES
REAR WHEEL ALIGNMENT INSPECTIONN17FAAC
The rear suspension assembly must be free of worn, loosen or
damaged parts prior to measurement of rear wheel alignment.
Standard value:
Toe-in (Left-right difference)
Of3 mm (Of.118 in.)
Camber-45’ + 30’
NOTEThe rear wheel alignment is set at the factory and cannot be
adjusted.If toe-in or camber is not within the standard value, replace
bent or damaged parts.
WHEEL BEARING END PLAY ADJUSTMENT,7FBA0
1.Inspect the play of the bearings while the vehicle is jacked
up and resting on floor jack.
2.Remove the hub cap and then release the parking brake.
3. Remove the caliper assembly and the brake disc.
4. Check the bearing’s end play.
Place a dial gauge against the hub surface; then move the
hub in the axial direction and check whether or not there isend play.
Limit: 0.01 mm
(.004 in.) or less
NOTE12AO531If the limit value is exceeded, the lock nut should be
tightened to the specified torque and check the end play
again.
5.Replace the rear hub bearing unit if an adjustment cannot
be made to within the limit.

SERVICE ADJUSTMENT PROCEDURES
TIRE INFLATION PRESSURE CHECKN2ZFOACCheck the inflation pressure of the tires. If it is not within the
standard value, make the necessary adjustment.
TIRE WEAR CHECKN2zFsABMeasure the tread depth of tires.Limit:
1.6 mm (.06 in,)If the remaining tread depth is less than the limit, replace the
tire.
NOTEWhen the tread depth of tires is reduced to 1.6 mm
(.06 in.) or
less, wear indicators will appear.
WHEEL RUNOUT CHECKNZ2FCA5Jack up the vehicle so that the wheels are clear of the floor.
While slowly turning the wheel, measure wheel
runout with a
dial indicator.Limit:

INSTRUCTIONS FOR ALUMINUM TYPE
WHEELSUzzGfM
1. Aluminum is vulnerable to alkalies. If a vehicle
washing detergent has been used, or salt from
sea water or road chemicals has adhered, washthe vehicle as soon as possible. After washing
the vehicle, apply body or wheel wax to the
aluminum type wheels to prevent corrosion.
2. When cleaning the vehicle with steam, do not
direct steam onto the aluminum type wheels.
When tightening nuts for aluminum type
wheels, particularly observe the following:
(1) Clean the hub surface of aluminum type
wheels.(2) After finger-tightening wheel nuts, tighten
them to specifications.
(3) Do not use an impact wrench or push the
wrench by foot to tighten the wheel nuts.
(4) Do not apply oil to the threaded portions.
INSTRUCTIONS FOR TIRE CHAINS AND
SNOW TIRESNZZGGAA
1.Use tire chains only on front wheels. Do not usetire chains on rear wheels.
2. When using snow tires, use them on all four
wheels for maneuverability and safety.
INSTRUCTIONS FOR COMPACT SPARE
TIRE;c.1. The compact spare tire is designed to. save
space in the luggage compartment, and its
L’lighter weight makes it easier to use if a fiat tire
occurs.
2.The following instructions for the compact sparetire should be observed.
(1) Check the inflation pressure after installing
the spare, and adjust to the specified pres-
sure.(2) Avoid driving through automatic car washes
and over obstacles that could possibly dam-
age the vehicle’s undercarriage. Because
the tire is smaller than the original tire, car
ground clearance is slightly reduced.
(3) The compact spare tire should not be used
on any other wheels, nor should standard
tires, snow tires, wheel covers or trim rings
be used with the compact spare wheel. If
such use is attempted, damage to these
items or other vehicle components may
occur.
