ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 15 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within the range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE

Check engine oil for white turbidity or heavy contamination.

If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for oil leakage around the following area.

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

Oil cooler

Intake valve timing control cover

Intake valve timing control solenoid valve

Front cover

Chain tensioner cover

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Crankshaft oil seals (front and rear)
OIL PRESSURE CHECK
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-25, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.

3. Disconnect harness connector at oil pressure switch, and remove oil pressure switch using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.
4. Install oil pressure gauge and hose (SST).
5. Start engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load. NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
If difference is extreme, check oil passage and oil pump for oil leaks.
7. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil presser switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to the specification. Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-48, "
RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .
c. After warming up engine, make sure there is no leakage of engine oil with running engine.

OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc. Item
Reference page
Tires Check the pressure with a gauge, including the spare, at least once a month
and always prior to a long distance trips. Adjust to the specified pressure if
necessary. Check carefully for damage, cuts or excessive wear. —
Wheel nuts When checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary. —
Windshield Clean the windshield on a regular basis. Check the windshield at least every
six months for cracks or other damage. Repair as necessary. —
Tire rotation Tires should be rotated every 12,000 km (7,500 miles). MA-35
Wheel alignment and
balance If the vehicle pulls to either side while driving on a straight and level road, or if
you detect uneven or abnormal tire wear, there may be a need for wheel align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel
balancing may be needed. MA-33
,
FSU-6
Windshield wiper
blades Check for cracks or wear if they do not wipe properly. —
Doors and engine
hood Check that all doors and the engine hood operate smoothly as well as the
trunk lid and back hatch. Also make sure that all latches lock securely. Lubri-
cate if necessary. Make sure that the secondary latch keeps the hood from
opening when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently. MA-38
Lamps
Make sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim. Clean the headlamps on a regular basis. —
Item
Reference page
Warning lamps and
chimes Make sure that all warning lamps and chimes are operating properly. —
Windshield wiper and
washer Check that the wipers and washer operate properly and that the wipers do not
streak. —
Windshield defroster Check that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioner. —
Steering wheel Check that it has the specified play. Be sure to check for changes in the steer-
ing condition, such as excessive play, hard steering or strange noises.
Free play: Less than 35 mm (1.38 in) —
Seats Check seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every
position. Check that the head restrains move up and down smoothly and that
the locks (if equipped) hold securely in all latched positions. Check that the
latches lock securely for folding-down rear seatbacks. —
Seat belts Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters
and retractors) operate properly and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying, wear or damage. MA-39
Accelerator pedal
Check the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal. —
Brakes Check that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
booster Check the pedal for smooth operation and make sure it has the proper dis-
tance under it when depressed fully. Check the brake booster function. Be
sure to keep the floor mats away from the pedal. BR-6

WARNING:

To avoid being scalded, do not change engine coolant when the engine is hot.

Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.

Be careful not to allow engine coolant to contact drive belts.
DRAINING ENGINE COOLANT
1. Remove front engine undercover with power tool.
2. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to EM-124, "

Checking Drive BeltsNLS0006C
WARNING:
Be sure to perform when the engine is stopped.

Remove air duct (inlet) when inspecting drive belt for alternator, water pump and A/C compressor.

Remove front engine undercover with power tool when inspecting power steering oil pump belt.

Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range
(between three line notches).
NOTE:

Check auto tensioner indication when engine is cold.

When new drive belt is installed, the range should be “A”.

The indicator notch is located on the moving side of the tensioner for alternator, water pump and A/C
compressor belt, while it is found on the fixed side for power steering oil pump belt.

Visually check entire belt for wear, damage or cracks.

If the indicator is out of allowable working range or belt is damaged, replace belt.
Tension AdjustmentNLS0006D
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
Changing Engine CoolantNLS0006E
WARNING:

To avoid being scalded, do not change engine coolant when engine is hot.

Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
