(driver side) and front door switch (passenger switch) are turned OFF.
TRUNK ROOM LAMP OPERATION
When trunk lid lock assembly (trunk room lamp switch) is turned ON (trunk lid is opened), trunk room lamp turn
ON. Power is supplied

through 10A fuse [No. 21, located in fuse block (J/B)]

to trunk room lamp terminal 1.
Ground is supplied

to trunk room lamp terminal 2

through BCM terminal 64.
With power and ground supplied, trunk room lamp illuminate.
And, trunk room lamp turns OFF when trunk lid lock assembly (trunk room lamp switch) is turned OFF.
INTERIOR ROOM LAMP TIMER OPERATION
The interior room lamp timer controls to turn ON/OFF of the map lamp, personal lamps and ignition keyhole
illumination when map lamp switch and personal lamp switch are in DOOR position.
BCM controls the interior room lamp timer according to the following signals.

Key switch signal

Door lock status signal (from front door lock assembly)

Front door switch (driver side) signal

Front door switch (passenger side) signal

Rear door switch RH signal

Rear door switch LH signal

Keyless lock/unlock signal (from remote keyless receiver)

Intelligent Key lock/unlock signal (from Intelligent Key unit through CAN communication)
And when those lamps are turned ON/OFF, the interior room lamp timer executes brightening/dimming control
for maximum 5 seconds. Brightening/dimming control time can be changed with CONSULT-II. Refer to LT- 2 3 3 ,

PERIODIC MAINTENANCE

PERIODIC MAINTENANCEPFP:00026
Periodic MaintenanceBLS0008Z
The following tables show the normal maintenance schedule. Depending upon weather and atmospheric con-
ditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent mainte-
nance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
ENGINE AND EMISSION CONTROL MAINTENANCE
(Annual Mileage <30,000 Km [18,000 miles]/year)
QR and VQ ENGINE
Abbreviations: I = Inspect and correct or replace as necessary, R = Replace
[ ] = At the specified distance only
NOTE:

(1) Periodic maintenance is not required. However, if valve noise increases, check valve clearance.

(2) Replace the drive belt if found damaged or if the auto tensioner reading (for QR20DE engine) reaches the maximum
limit.

(3) First replace at 100,000 km (60,000 miles)/60 months, then every 60,000 km (36,000 miles)/48 months. Perform “I”
(Checking the mixture ratio and correcting the mixture ratio if necessary) at the middle of replacement interval.

(4) Fuel filter is maintenance-free. For service procedures, refer to FL section.

(5) Perform only according to “Maintenance Under Severe Driving Conditions” for models without Euro-OBD system.

Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”. MAINTENANCE OPERATIONMAINTENANCE INTERVAL Reference page
