PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions for Battery Service NBS00018

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Precautions for Liquid Gasket NBS00019

LIQUID GASKET APPLICATION PROCEDURE
1. Removal old liquid gasket adhering to the liquid gasket application surface and the mating surface.
q Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt
holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Apply liquid gasket to the liquid gasket application surface.
Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-45, "RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .
q Within five minutes of liquid gasket application, install the mating component.

q If liquid gasket protrudes, wipe it off immediately.

q Do not retighten mounting bolts or nuts after the installation.

q After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.

Inspection NBS0001E

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 10 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 (A) shown in the figure.
3. If it is out of range, adjust it.

PBIC4931E

NOTE:
When checking oil level, insert oil level gauge (1) with its tip aligned with oil level gauge guide on cylinder
head.
2 : Engine cover
: Engine front

PBIC4932E

ENGINE OIL APPEARANCE
q Check engine oil for white turbidity or heavy contamination.
q 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 areas:
q Oil pans (lower and upper)
q Oil pan drain plug
q Oil pressure sensor
q Oil filter
q Valve timing control cover
q Mating surface between cylinder head and rocker cover
q Mating surface between front timing chain case and rear timing chain case
q Mating surface between rear timing chain case and cylinder head
q Mating surface between rear timing chain case and cylinder block
q Mating surface between rear timing chain case and oil pan (upper)
q Mating surface between cylinder block and cylinder head
q Mating surface between lower cylinder block and cylinder block
q Crankshaft oil seals (front and rear)
q Camshaft position sensor and exhaust valve timing control position sensor.

ENGINE OIL

OIL PRESSURE CHECK
WARNING: A
q Be careful not to burn yourself, as engine oil may be hot.
q Oil pressure check should be done in "Neutral position" (M/T models) or "Parking position" (A/T
models). LU
1. Check the engine oil level. Refer to LU-6, "ENGINE OIL LEVEL" .
2. Remove undercover with power tool.
3. Disconnect harness connector at oil pressure sensor, and C
remove oil pressure sensor using deep socket (commercial ser-
vice tool).
CAUTION: D
Do not drop or shock oil pressure sensor.

5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load.
NOTE: K
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80
