WAR NING :
Be careful not to burn yourself, as engine oil may be 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. Refer to LU-26, "
ENGINE
OIL LEAKAGE" .
2. Stop engine and wait for 15 minutes.
3. Loosen oil filler cap.
4. Remove mounting bolts, and then pull down the rear of front engine undercover and secure it using clip.
5. Remove drain plug and then drain engine oil.
6. Install drain plug with new washer. Refer to EM-187, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Be sure to clean drain plug and install with new washer.

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

IPDM E/R STATUS CONTROL
In order to save power, IPDM E/R switches status by itself based on each operating condition.
1. CAN communication status
CAN communication is normally performed with other control units.
Individual unit control by IPDM E/R is normally performed.
When sleep request signal is received from BCM, mode is switched to sleep transient status.
2. Sleep transient status
Process to stop CAN communication is activated.
All systems controlled by IPDM E/R are stopped. When 3 seconds have elapsed after CAN communi-
cation with other control units is stopped, mode switches to sleep status.
3. Sleep status
IPDM E/R operates in low power mode.
CAN communication is stopped.
When a change in CAN communication line is detected, mode switches to CAN communication status.
When a change hood switch or ignition switch signal is detected, mode switches to CAN communica-
tion status.
CAN Communication System DescriptionNKS004E3
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicles are equipped with many electronic control units and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS004E4
Refer to LAN-34, "CAN Communication Unit" .
Function of Detecting Ignition Relay MalfunctionNKS004E5
When contact point of integrated ignition relay is stuck and cannot be turned OFF, IPDM E/R turns ON tail
and parking lamps for 10 minutes to indicate ignition relay malfunction.
When a state of ignition relay having built-in does not agree with a state of Ignition switch signal input by a
CAN communication from BCM, IPDM E/R lets tail lamp relay operate.
NOTE:
When the ignition switch is turned ON, the tail lamps are OFF.

TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
