4. Re-install in the reverse order of removal.
Replace the element according to the
Scheduled Maintenance.
If the vehicle is operated in extremely
dusty or sandy areas, replace the
element more often than at the usual
recommended intervals.
WIPER BLADESWIPER BLADE
MAINTENANCEContamination of either the windshield
or the wiper blades with foreign matter
can reduce the effectiveness of the
windshield wipers. Common sources of
contamination are insects, tree sap, and
hot wax treatments used by some
commercial car washes. If the blades are
not wiping properly, clean both the
window and the blades with a good
cleaner or mild detergent, and
thoroughly rinse with clear water.
WINDSHIELD WIPER BLADE
REPLACEMENTWhen the wipers no longer clean
adequately, the wiper blades may be worn
or cracked, requiring replacement.
MAINTENANCE
7-22
CAUTION
• Do not drive with the air cleaner
removed; this will result in
excessive engine wear.
• Driving without an air cleaner
encourages backfiring, which
could cause a fire in the engine
compartment.
✻
NOTICE
Commercial hot waxes applied by
automatic car washes have been
known to make the windshield
difficult to clean.
✻
NOTICE
To prevent damage to the wiper
blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.✻
NOTICE
To prevent damage to the wiper
arms or other components, do not
attempt to move the wipers
manually.

BATTERY MAINTENANCEFor best battery service:
• Keep the battery securely mounted.
• Keep the battery top clean and dry.
• Keep the terminals and connections
clean, tight, and coated with
petroleum jelly or terminal grease.
• Immediately rinse any spilled
electrolyte from the battery with a
solution of water and baking soda.
• If the vehicle is not going to be used
for an extended period of time,
disconnect the battery cables.
BATTERY RECHARGINGYour vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged in
a short time (headlights or interior
lights were left on while the vehicle
was not in use), recharge it by slow
(trickle) charging for 10 hours.
• If the battery gradually discharges
because of high electric load while
the vehicle is being used, recharge it
at 20-30A for two hours.
MAINTENANCE

(Continued)
Keep batteries out of the
reach of children
because batteries
contain highly corrosive
SULFURIC ACID. Do not allow
battery acid to contact your skin,
eyes, clothing or paint finish.
Wear eye protection
when charging or
working near a battery.
Always provide ventilation when
working in an enclosed space.
When lifting a plastic-cased
battery, excessive pressure
on the case may cause
battery acid to leak, resulting
in personal injury. Lift with a
battery carrier or with your
hands on opposite corners.
Never attempt to charge the
battery when the battery
cables are connected.
The electrical ignition system
works with high voltage. Never
touch these components with
the engine running or the
ignition switched on.
WARNING - Recharging
Battery
When recharging the battery,
observe the following
precautions:
The battery must be removed
from the vehicle and placed
in an area with good
ventilation.
Do not allow cigarettes,
sparks, or flame near the
battery.

TIRES AND WHEELSTIRE CAREFor proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within the
load limits and weight distribution
recommended for your vehicle.INFLATION PRESSURESCheck all tire pressures (including the
spare) monthly when the tires are cold.
“Cold tires” means the car has not been
driven for at least three hours or driven
less than one mile (1.6 km).
Recommended pressures must be
maintained to ensure ride quality, vehicle
handling, and minimum tire wear.
Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gasing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 120°F (49°C).
Wear eye protection when
checking the battery during
charging.
Disconnect the battery
charger in the following
order.
1. Turn off the battery
charger main switch.
2. Unhook the negative
clamp from the negative
battery terminal.
3. Unhook the positive clamp
from the positive battery
terminal.
✻
NOTICE
• Before performing battery
maintenance or recharging, turn
OFF all accessories and stop the
engine.
• When remounted battery,
disconnect the negative (-)
battery cable first. When re-
installing the battery, reconnect
the negative (-) battery cable
last.

REPLACEMENT (IF EQUIPPED)1. Remove the trunk room lamp cover
using flat blade screw driver.
2. After replacement of bulb, install the
cover.
LUBRICANT
SPECIFICATIONSRECOMMENDED
LUBRICANTSTo help achieve proper engine and
powertrain performance and durability,
use only lubricants of the proper quality.
The correct lubricants also help promote
engine efficiency which results in
improved fuel economy.
Engine oils labeled Energy Conserving
Oil are now available. Along with other
additional benefits, they contribute to
fuel economy by reducing the amount of
fuel necessary to overcome engine
friction. Often, these improvements are
difficult to measure in everyday driving,
but in a year’s time they can offer
significant cost and energy savings.

RECOMMENDED SAE
VISCOSITY NUMBEREngine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operation (starting and oil flow). Lower
viscosity engine oils can provide better fuel
economy and cold weather performance,
however, higher viscosity engine oils are
required for satisfactory lubrication in hot
weather. Using oils of any viscosity other
than those recommended could result in
engine damage.
These lubricants and fluids are recommended for use in your vehicle.*1)
Refer to the recommended SAE viscosity numbers on the this page.
* Recommended for the Canadian climate.
Lubricant Classification
Engine oil* API Service SJ, SL or above,
ILSAC GF-3 or above
Manual transaxle oil* API Service GL-4 (SAE 75W-85)
Automatic trasaxle fluid SK ATF SP-III or Diamond ATF SP-III
Power steering fluid PSF-IV
Brake/clutch fluid SAEJ1703 or FMVSS116 DOT-3 DOT-4
✻
NOTICE
Always be sure to clean the area
around any filler plug, drain plug,
or dipstick before checking or
draining any lubricant. This is
especially important in dusty or
sandy areas and when the vehicle is
used on unpaved roads. Cleaning
the plug and dipstick areas will
prevent dirt and grit from entering
the engine and other mechanisms
that could be damaged.

7-42HEADLIGHT AIMING
ADJUSTMENTBefore performing aiming adjustment,
make sure of the following.
1. Keep all tires inflated to the correct
pressure.
2. Place the vehicle on level ground and
press the front bumper & rear
bumper down several times.
3. See that the vehicle is unloaded
(except for full levels of coolant,
engine oil and fuel, and spare tire, jack,
and tools). Have the driver sit in the
driver’s seat or use equivalent weight.4. Clean the headlight lenses and turn
on the headlight (Low beam).
5. Open the hood.
6. Draw a vertical line (through the
center of each headlight) and the
horizontal line (through the center of
each headlight) on the aiming screen.
1) Horizontal line dimension from
ground: 628 mm (24.72 in)
2) Distance between each vertical
line : 1,306 mm (49.17 in)
And then, draw a parallel line at 30
mm (1.18 in) place under the
horizontal line.
7. Adjust each cut-off line of the low
beam to the parallel line with a
Phillips screwdriver.
ADJUSTMENT AFTER
HEADLIGHT ASSEMBLY
REPLACEMENTIf the vehicle has had front body repair
and the headlight assembly has been
replaced, the headlight aiming should be
checked using the aiming screen as
shown in the illustration. Turn on the
headlight switch. (Low Beam Position)
1. Adjust headlights so that main axis of
light is parallel to center line of the
body and is aligned with point “P”
shown in the illustration.
