Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”.
MAINTENANCE UNDER SEVERE DRIVING CONDITIONS
(Annual Mileage >30,000 Km/year)
The maintenance intervals shown on the preceding pages are for normal operating conditions. If the vehicle is
mainly operated under severe driving conditions as shown below, more frequent maintenance must be per-
formed on the following items as shown in the table.
Severe driving conditions
A — Driving in dusty conditions
B — Repeatedly driving short distances
C — Towing a trailer or caravan
D — Extensive idling
E — Driving in extremely adverse weather conditions or in areas where ambient temperatures are either
extremely low or extremely high
F — Driving in high humidity or mountainous areas
G — Driving in areas using salt or other corrosive materials
H — Driving on rough and/or muddy roads or in the desert
I — Driving with frequent use of braking or in mountainous areas
J — Frequent off road use or driving in water
K —Sustained high speed driving
L — For models without Euro-OBD system

CAUTION:

The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.

Always use oil level gauge to the determine when the proper amount of engine oil is in the
engine.
7. Warm up engine and check area around drain plug and oil filter for oil leakage.
8. Stop engine and wait for 10 minutes.

Checking and Changing Spark PlugsELS000ZK
REMOVAL
1. Remove ignition coil. Refer to EM-29, "IGNITION COIL" .
2. Remove spark plug with spark plug wrench (commercial service
tool).
CAUTION:
Do not drop or shock it.
INSPECTION AFTER REMOVAL
Use standard type spark plug for normal condition.
Hot type spark plug is suitable when fouling occurs with standard type spark plug under conditions such as:

Frequent engine starts

Low ambient temperatures
Cold type spark plug is suitable when spark plug knock occurs with standard type spark plug under conditions
such as:

Extended highway driving

Frequent high engine revolution

Check plug gap of each spark plug.

If out of standard, adjust or replace spark plug.

Use a wire brush for cleaning, if necessary.
INSTALLATION
Install in the reverse order of removal.
Checking EVAP Vapor LinesELS000ZL
1. Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration.
2. Inspect fuel tank filler cap vacuum relief valve for clogging, sticking, etc.
Refer to EC-474, "
EVAPORATIVE EMISSION LINE DRAWING" .

Changing Engine OilELS000CH
WARNING:

Be careful not to burn yourself, as the engine oil is hot.

Prolonged and repeated contact with used engine oil may cause skin cancer: try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for engine oil leakage from engine components.
2. Stop engine and wait for 10 minutes.
3. Loosen oil filter cap and then remove drain plug.
4. Drain engine oil.
5. Install drain plug with new washer. Refer to EM-147, "
OIL PAN
AND OIL STRAINER" .
CAUTION:
Be sure to clean drain plug and install with new washer.
6. Refill with new engine oil.
Engine oil specification and viscosity:
Refer to MA-17, "

Always use the dipstick to the determine when the proper amount of engine oil is in the engine.
7. Warm up engine and check area around drain plug and oil filter for oil leakage.
8. Stop engine and wait for 10 minutes.
9. Check the engine oil level.
Changing Oil Filter (TYPE A)ELS000CI
REMOVAL
1. Open oil filter installation/ removal cover on RH engine undercover.
2. Using the oil filter wrench, remove the oil filter.
CAUTION:

Be careful not to get burned when the engine and engine oil are hot.

When removing, prepare a shop cloth to absorb any engine oil leakage or spillage.

Do not allow engine oil to adhere to the drive belts.

Completely wipe off any engine oil that adhere to the engine and the vehicle.Oil pan drain plug:

CHASSIS AND BODY MAINTENANCE

Changing M/T OilELS000BD
1. Drain oil from drain plug and refill with new gear oil.
2. Check oil level.
CAUTION:
Do not reuse gasket.
Checking A/T FluidELS000BV
1. Warm up engine.
2. Check for fluid leakage.
3. Before driving, fluid level can be checked at fluid temperatures of 30 to 50°C (86 to 122°F) using “COLD”
range on dipstick.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear position. Leave selector lever in “P” position.
c. Check fluid level with engine idling.
d. Remove dipstick and wipe clean lint-free paper.
CAUTION:
When wiping away the dipstick, always use lint-free paper, not cloth one.
e. Re-insert dipstick into charging pipe as far as it will go.
CAUTION:
To check fluid level, insert the dipstick until the cap contacts the end of the A/T fluid charging pipe,
with the dipstick reversed from the normal attachment conditions.
f. Remove dipstick and note reading. If reading is at low side of range, add fluid to the A/T fluid charging
pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Re-check fluid level at fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on dipstick.
CAUTION:

When wiping away the dipstick, always use lint-free paper, not cloth one.

To check fluid level, insert the dipstick until the cap contacts the end of the A/T fluid charging
pipe, with the dipstick reversed from the normal attachment conditions.Oil grade:

CHASSIS AND BODY MAINTENANCE

Checking Power Steering Fluid and LinesELS000BP
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80°C (122 to 176°F)
or “COLD” range at fluid temperatures of 0 to 30°C (32 to 86°F).
CAUTION:

Do not overfill.

Recommended fluid is DEXRONTM III type ATF or equiva-
lent.
Refer to MA-17, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS"


Check lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.

Check rack boots for accumulation of power steering fluid.
Axle and Suspension PartsELS000BQ
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.

Shake each wheel to check for excessive play.

Check wheel bearings for smooth operation.

Check axle and suspension nuts and bolts for looseness.

Check strut (shock absorber) for oil leakage or other damage.

Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.
