CAUTION
●Always connect positive (+) to positive (+)
and negative () to body ground (as illus-
trated) — not to the battery.
● Make sure the jumper cables do not touch
moving parts in the engine compartment and
that clamps do not contact any other metal.
5. Start the engine of the booster vehicleA
and let it run for a few minutes.
6. Keep the engine speed of the booster vehicle
Aat about 2,000 rpm, and start
the engine of the vehicle being jump
started
B.
CAUTION
Do not keep the starter motor engaged for more
than 10 seconds. If the engine does not start
right away, push the ignition switch to the OFF
position and wait 10 seconds before trying
again.
7. After starting your engine, carefully dis- connect the negative cable and then the
positive cable (
4→3→2→1). 8. Replace the vent caps (if so equipped). Be
sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
9. Put the battery cover on.
Do not attempt to start the engine by pushing.
CAUTION
● Automatic transmission models cannot be
push-started or tow-started. Attempting to
do so may cause transmission damage.
● Three way catalyst equipped models should
not be started by pushing since the three
way catalyst may be damaged.
● Never try to start the vehicle by towing it;
when the engine starts, the forward surge
could cause the vehicle to collide with the
tow vehicle.
If needed, Roadside Assistance is available.

TOWING RECOMMENDED BY INFINITI
Two-Wheel Drive (2WD) models
INFINITI recommends that your vehicle be towed
with the driving (rear) wheels off the ground or
place the vehicle on a flat bed truck as illus-
trated.
CAUTION
●Never tow automatic transmission models
with the rear wheels on the ground or four
wheels on the ground (forward or backward),
as this may cause serious and expensive
damage to the transmission. If it is neces-
sary to tow the vehicle with the front wheels
raised, always use towing dollies under the
rear wheels. ●
When towing rear wheel drive models with
the front wheels on the ground or on towing
dollies: Push the ignition switch to the ACC
or ON position, and secure the steering
wheel in a straight-ahead position with a
rope or similar device. Never secure the
steering wheel by selecting the LOCK posi-
tion. This may damage the steering lock
mechanism.

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
●Park the vehicle on a level surface, apply the
parking brake securely and block the wheels
to prevent the vehicle from moving. Move
the selector lever to P (Park).
● Be sure the ignition switch is in the OFF or
LOCK position when performing any parts
replacement or repairs.
● Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
● Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition switch is in the
ON position.
● If you must work with the engine running,
keep your hands, clothing, hair and tools
away from moving fans, belts and any other
moving parts. ●
It is advisable to secure or remove any loose
clothing and remove any jewelry, such as
rings, watches, etc. before working on your
vehicle.
● Always wear eye protection whenever you
work on your vehicle.
● If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
● Never get under the vehicle while it is sup-
ported only by a jack. If it is necessary to
work under the vehicle, support it with
safety stands.
● Keep smoking materials, flame and sparks
away from fuel tank and the battery.
● Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
key is in the OFF position and the engine is
not running. To avoid injury, always discon-
nect the negative battery cable before work-
ing near the fan.
● The fuel filter or fuel lines should be serviced
by an INFINITI retailer because the fuel lines
are under high pressure even when the en-
gine is off.
CAUTION
● Do not work under the hood while the engine
is hot. Turn the engine off and wait until it
cools down.
● Avoid direct contact with used engine oil and
coolant. Improperly disposed engine oil,
coolant, and/or other vehicle fluids can dam-
age the environment. Always conform to lo-
cal regulations for disposal of vehicle fluid.
This “8. Maintenance and do-it-yourself” sec-
tion gives instructions regarding only those
items which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also avail-
able. (See “OWNER’S MANUAL/SERVICE
MANUAL ORDER INFORMATION” in the “9. Tech-
nical and consumer information” section.)
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage. If in doubt about any
servicing, we recommend that it be done by an
INFINITI retailer.

CAUTION
●Do not ground accessories directly to the
battery terminal. Doing so will bypass the
variable voltage control system and the ve-
hicle battery may not charge completely.
● Use electrical accessories with the engine
running to avoid discharging the vehicle
battery.
The variable voltage control system measures
the amount of electrical discharge from the
battery and controls voltage generated by the
generator.
1. Power steering fluid pump
2. Alternator
3. Crankshaft pulley
4. Air conditioner compressor
5. Drive belt auto-tensioner
WARNING
Be sure the ignition switch is in the OFF or LOCK
position before servicing drive belts. The en-
gine could rotate unexpectedly.
1. Visually inspect each belt for signs of unusual wear, cuts, fraying or looseness.
If the belt is in poor condition or loose,
have it replaced or adjusted by an INFINITI
retailer.
2. Have the belts checked regularly for con- dition and tension in accordance with the
maintenance schedule in your “INFINITI
Service and Maintenance Guide”.VK56VD engine

WARNING
Be sure the engine and the ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to remove the
spark plugs. An incorrect socket can damage
the spark plugs.
REPLACING SPARK PLUGS
If replacement is required, see an INFINITI re-
tailer for servicing.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much
longer. Follow the maintenance schedule in
“INFINITI Service and Maintenance Guide”, but
do not reuse them by cleaning or regapping.
Always replace spark plugs with recommended
or equivalent ones.
