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.ItemReference page
TiresCheck 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 nutsWhen checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.—
WindshieldClean the windshield on a regular basis. Check the windshield at least every
six months for cracks or other damage. Repair as necessary.—
Tire rotationTires should be rotated every 12,000 km (7,500 miles).MA-35
Wheel alignment and
balanceIf 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
(2WD),
FSU-23
(AWD)
Windshield wiper
bladesCheck for cracks or wear if they do not wipe properly. —
Doors and engine
hoodCheck that all doors and the engine hood operate smoothly as well as the
trunk lid. Also make sure that all latches lock securely. Lubricate if necessary.
Make sure that the secondary latch keeps the hood from opening when the pri-
mary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently.MA-38
LampsMake 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. —
ItemReference page
Warning lamps and
chimesMake sure that all warning lamps and chimes are operating properly. —
Windshield wiper and
washerCheck that the wipers and washer operate properly and that the wipers do not
streak.—
Windshield defrosterCheck that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioner.—
Steering wheelCheck 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)—
SeatsCheck 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 beltsCheck 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 pedalCheck 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.—
BrakesCheck that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
boosterCheck 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

ENGINE MAINTENANCE (VK45DE ENGINE)PFP:10001
Checking Drive BeltsNLS0007Q
WAR NING :
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.
Te n s i o n A d j u s t m e n tNLS0007R
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
Changing Engine CoolantNLS0007S
WAR NING :
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
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 engine room cover (RH and LH) Refer to EM-173, "ENGINE ROOM COVER" .
2. Remove engine cover with power tool. Refer to EM-179, "
INTAKE MANIFOLD" .
3. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
