l Fuel economy unsatisfactory TION
[TROUBLESHOOTING HINTS]
While fuel consumption is drastically increased by city driving, short-run operation, stop and go driving, extended winter
warm-up periods, etc., as opposed to “trip” mileage, an attempt should be made to determine these factors when con-
fronted with “poor mileage” conditions. However, since the operator is not always at fault, the following is offered.
@II Operator depressing accelerator more than usual due to
@ Air/Fuel mixture too rich
low engine power
l Poor ignition *High fuel line pressure
@ Alcohol blended fuel used
*Low intake air amount
l Electronic spark advance control system malfunction @ High vehicle load l Low tire pressure
*Clutch slipping/ATX slipping l Incorrect tire size l Exhaust component restricted l Brake dragging ;TEP

Caution
l Do not start the engine.
l Jack up the front of the vehicle.
1. Check the fluid level. (Refer to page N-27.)
2. Turn the steering wheel fully to the left and right several times
with the engine not running.
3. Recheck the fluid level. If the level has lowered, add fluid.
4. Repeat steps 2 and 3 until the fluid level stabilizes.
5. Start the engine and let it idle.
6. Turn the steering wheel fully to the left and right several
times.
7. Check that the fluid is not foamy and that the fluid level has
not dropped.
8. Add fluid if necessary and repeat steps 6 and 7.
STEERING WHEEL AND COLUMN
Inspection (On-vehicle)
Steering wheel effort
1. With the vehicle on a hard, level surface, put the wheels
in the straight-ahead position.
2. Start the engine and warm the power steering fluid to
50-60°C
(122-14OOF) by turning the steering: wheel fully
left and right several times.
3. With the engine running at idle speed, attach a pull scale
to the outermost point of the steering wheel spoke. Then,
starting with the wheels in the straight-ahead position, check
the steering effort required to turn the steering wheel to the
left and to the right.
4. If the measured effort exceeds specification, check the fol-
lowing: fluid level, air in system, fluid leakage at hose or con-
nections, function of P/S oil pump and gearbox, and tire
pressures.
Steering wheel effort: 29 N (3.0 kg, 6.6 lb) or less 03UONX-033

WHEELS AND TIRES
SPECIAL NOTES ABOUT WHEELS AND TIRES
1. Do not use wheels or tires other than the specified types.
2. Aluminum wheels are easily scratched. When washing them, use a soft cloth, never a wire brush. If the
vehicle is steam cleaned, do not allow boiling water to contact the wheels.
3. If alkaline compounds (such as saltwater or road salts) get on aluminum wheels, wash them as soon as
possible to prevent damage. Use only a neutral detergent.
9MUOQX-004
NOTES REGARDING TIRE REPLACEMENT
Note the following points when tires are to be removed from or mounted onto the wheels.
1. Be careful not to damage the tire bead, the rim bead, or the edge of the rim.
2. Use a wire brush, sandpaper, or cloth to clean and remove all rust and dirt from the rim edge and the
rim bead.
3. When cleaning aluminum wheels, use a soft cloth, never a wire brush or sandpaper.
4. Remove any pebbles, glass, nails, and other foreign items embedded in the tire tread.
5. Be sure the air valve is installed correctly.
6. Apply a soapy solution to the tire bead and the edge of the rim.
7. After mounting a tire onto a wheel, inflate the tire to 250-300 kPa (2.55-3.06 kg/cm2, 35.55-42.66
psi). Check to be sure that the bead is seated correctly onto the rim and that there are no air leaks. Then
reduce the pressure to the specified level.
8. If a tire iron is used to change a tire on an aluminum wheel, be sure to use a piece of rubber between
the iron lever and the wheel to avoid damage to the wheel. Work should be done on a rubber mat, not
on a hard or rough surface.
