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 Measure the gap around the entire circumference
of the selector
13. Use a feeler gauge to measure the gap in the selector for
the differential.
14. Add 0.15mm (0.0059 in) to the measured clearance and
select the combination of shims closest in value to that meas-
urement.
Note
l Use a maximum of two shims.
See the table below for available shim sizes.
Example: 0.32mm (0.013 in)
0.32mm (0.013 in) + 0.15mm (0.006 in) = 0.47mm
(0.019 in).
So the nearest shim (on the thick side) to 0.47mm
(0.019 in) is 0.50mm (0.020 in).
15. Remove the SST and the transaxle case.
16. Remove the selectors, the primary shaft assembly and the
-differential.
17. Remove the bearing outer races.
Assembly note
Oil seals
1. Apply transaxle oil to outer periphery.
2. Install the new oil seals with the SST.
Diaphragm spring
1. Install the diaphragm spring as shown in the figure.
Boot
1. Install the boot with the drain hole facing downward.

WHEELS AND TIRES
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.
