PRECAUTIONS
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precautions for Three Way CatalystBAS00074
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
When checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary.
Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to
the catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precautions for FuelBAS0008E
QR20DE/VQ23DE ENGINE (REGULAR GASOLINE, UNLEADED PREMIUM GASOLINE RECOM-
MENDED)
Use unleaded regular gasoline with an octane rating of at least 91 RON (research octane number).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
VQ35DE ENGINE (PREMIUM GASOLINE)
Use unleaded premium gasoline with an octane rating of at least 95 RON (research octane number).
If unleaded premium gasoline is not available, unleaded regular gasoline with an octane rating of at least 91
RON (research octane number) can be used, but only under the following precautions:
have the fuel tank filled only partially with unleaded regular gasoline, and fill up with unleaded premium
gasoline as soon as possible.
avoid full throttle driving and abrupt acceleration.
However, for maximum vehicle performance, the use of unleaded premium gasoline is recommended.
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
Precautions for Multiport Fuel Injection System or Engine Control SystemBAS0008F
Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
Be careful not to jar components such as ECM and mass air
flow sensor.

PRECAUTIONS
Precautions for Engine OilsBAS0008H
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
Avoid prolonged and repeated contact with oils, particularly used engine oils.
Wear protective clothing, including impervious gloves where practicable.
Do not put oily rags in pockets.
Avoid contaminating clothes, particularly underpants, with oil.
Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.
First aid treatment should be obtained immediately for open cuts and wounds.
Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepa-
rations containing lanolin replace the natural skin oils which have been removed.
Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
If skin disorders develop, obtain medical advice without delay.
Where practical, degrease components prior to handling.
Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face
shields; in addition an eye wash facility should be provided.
Precautions for Air Conditioning BAS0008I
Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to
ATC/MTC section “HFC-134a (R-134a) Service Procedure”, “REFRIGERANT LINES” for specific instructions.

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
