●Use approved bonding agent, sealants or their equivalents when required.
●Use tools and recommended special tools where specified for safe and efficient service repairs.
●When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
●Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
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 All Mode 4 × 4 SystemEAS000GQ
Even if the 2WD mode is selected, the All mode 4 × 4 system occasionally changes from 2WD to 4WD auto-
matically depending on the driving conditions.
When spinning the front wheels by running the engine with the front wheels jacked up or mounted on the free
rollers / or a chassis dynamometer, be careful because the vehicle may suddenly move due to the driving
force from the rear wheels.
To avoid personal injury and vehicle damage, use one of the following methods when working with the front
wheels drive force and spinning freely.
● Remove the propeller shaft.
● Use free rollers / chassis dynamometer designed for 4WD vehicles.
Precautions for Three Way CatalystEAS000FR
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 FuelEAS000P9
GASOLINE ENGINE
Use unleaded gasoline with an octane rating of at least 95 (RON).
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.
DIESEL ENGINE
Diesel fuel of at least 50 cetane.
If two types of diesel fuel are available, use summer or winter fuel properly according to the following temper-
ature conditions.
●Above –7°C (20°F) ... Summer type diesel fuel.
●Below –7°C (20°F) ... Winter type diesel fuel.

LIFTING POINTPFP:00000
Special Service Tools EAS000FH
CAUTION:
●Every time the vehicle is lifted up, maintain the complete vehicle curb condition.
●Since the vehicle's center of gravity changes when removing main parts on the front side (engine,
transmission, suspension etc.), support a jack up point on the rear side garage jack with a mission
jack or equivalent.
●Since the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,
suspension, etc.), support a jack up point on the front side garage jack with a mission jack or
equivalent.
●Be careful not to smash or do not do anything that would affect piping parts.
Garage Jack and Safety Stand EAS000FI
WARNING:
●Park the vehicle on a level surface when using the jack. Make sure to avoid damaging pipes,
tubes, etc. under the vehicle.
●Never get under the vehicle while it is supported only by the jack. Always use safety stands when
you have to get under the vehicle.

TOWING THE VEHICLE WITH REAR WHEELS RAISED (WITH FRONT WHEELS ON GROUND)
OR FRONT WHEELS RAISED
Never tow the vehicle with rear wheels raised (with front wheels on
ground) or front wheels raised as this may cause serious and expen-
sive damage to the transaxle. If it is necessary to tow it with rear
wheels raised or front wheels raised, always use a towing dolly
under the front wheels.
If the speed or distance must necessarily be greater, remove the
front and rear propeller shafts beforehand to prevent damage to the
transaxle.
Vehicle Recovery (Freeing a stuck vehicle) EAS000FM
●Use the towing hook only, not other parts of the vehicle. Other-
wise, the vehicle body will be damaged.
●Use the towing hook only to free a vehicle stuck in sand, snow,
mud, etc. Never tow the vehicle for a long distance using only
the towing hook.
●The towing hook is under tremendous force when used to free a
stuck vehicle. Always pull the cable straight out from the front or
rear of the vehicle. Never pull on the hook at an angle.
●Stand clear of a stuck vehicle.
WARNING:
●Do not spin the tires at high speed. This could cause them
to explode and result in serious injury. Parts of the vehicle
could also overheat and be damaged.

Checking Drive BeltsEBS00KN7
WARNING:
Be sure to perform when the engine is stopped.
●Make sure that the indicator (single line notch on fixed side) of drive belt auto-tensioner is within the pos-
sible use range (between three line notches on moving side).
NOTE:
●Check the drive belt auto-tensioner indicator (single line notch on fixed side) when the engine is cold.
●When the new drive belt is installed, the indicator (single line notch on fixed side) should be within the
range A.
●Visually check entire belt for wear, damage or cracks.
●If the indicator (single line notch on fixed side) is out of possible use range or belt is damaged, replace the
belt.
Tension AdjustmentEBS00KN8
Belt tensioning is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationEBS00KN9
REMOVAL
1. Remove splash cover on RH undercover.
2. With box wrench, and while securely holding the hexagonal part
in pulley center of drive belt auto-tensioner, move the wrench
handle in the direction of arrow (loosening direction of ten-
sioner).
CAUTION:
Avoid placing hand in a location where pinching may occur
if the holding tool accidentally comes off.
3. Insert a rod approximately 6 mm (0.24 in) in diameter into retain-
ing boss to fix auto-tensioner pulley.
●Leave auto-tensioner pulley arm locked until belt is installed
again.
4. Loosen drive belt from water pump pulley in sequence, and remove it.

WARNING:
●Situate vehicle on a flat and solid surface.
●Place chocks at front and back of rear wheels.
●For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.
CAUTION:
●Always be careful to work safely, avoid forceful or uninstructed operations.

●If items or work required are not covered by the engine main body section, refer to the applicable
sections.
●Always use the support point specified for lifting.
●Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for
unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool
before starting work, in preparation for the backward shift of center of gravity.
●For supporting points for lifting and jacking point at rear axle, refer to GI-35, "Garage Jack and
Safety Stand" .
