GENERAL Maintenance Service
2.Check the wheel cylinder boots for evidence, a’ brake
fluid leak. Visually check the
boots for tears or
cracks. (A slight amount of fluid on the boot may not
be a leak, but may be preservative assembly.)
Caution
The shoes for the right and left be,
replaced at the same time.
Never split or intermix brake
sets.
All four shoes must be replaced as a set.
Thickness of lining
Limit: 1.0 mm in.)
17. BRAKE HOSES (Check for
leaks)
Check of brake hoses and tubing should be
brake service operations.
The hoses should be checked for:
1.Correct length, severe surface cracking, pulling, scuffing
or worn spots. (If the fabric casing of the hoses i s exposed
by cracks of abrasion in the rubber hose cover, the hoses
should be replaced. Eventual deterioration of may
occur with possible bursting failure.)
2. Faulty installation, casing twisting or interfer ence
wheel,’ tire or chassis.
18. BALL JOINT AND STEERING SEALS
(Check for grease leaks damage)
1. These components, which are permanently lubricat ed
at the factory, do not require periodic lubrication. Damaged
seals and boots should be replaced to prevent leakage
or contamination of the grease.
2.Check the dust cover and boots for proper sealing, leakage
and damage. Replace them if defective.
19. DRIVE SHAFT BOOTS (Check for leaks
and damage)
1. These components, which are permanently lubricat ed
at the factory, do not require periodic Damaged
boots should be replaced to prevent leakage or contamina-
tion of the grease.
2.Check the boots for proper sealing, leakage and damage.
Replace it if defective.
AXLE OIL (Check oil level)-AWD
Remove the filler plug and check the oil level at bottom of
filler hole. If the oil level is slightly below the filler hole, it
is in satisfactory condition.

Caution
1. Always apply the brakes when shifting the select or lever to ran&, or vehicle will
forward.
2. Driving tests always need another personnel.
NOTE
In a new vehicle [driven approximately 500 km (300 mile) or less], the volume air sensor output
is sometimes 10 higher than the standard frequency.
The injector drive time represents the time when the cranking speed is at 250 or below when the
supply voltage is 11 V.
In a new vehicle [driven approximately 500 km (300 mile) or less], the injector drive time is sometimes
longer than the standard time.
Fuel is injected into all cylinders simultaneously.
In a new vehicle [driven approximately km (300 mile) or less], the step of the stepper mo tor is sometimes
30 steps greater than the standard value.
If the throttle position sensor voltage rises 100 from the voltage when the engine is at idle and th e
closed throttle position switch turns from on to of f at this time, the sensors are normal. If the throttle position
sensor voltage rises 100
from the voltage when the engine is at idle, the t hrottle valve opens, and the
closed throttle position switch turns from on to of f at this, time, the sensors should be adjusted.
