move rings, metal bands, or any other
jewelry. Do not lean over the battery
when jump starting.
. Do not attempt to jump start a
frozen battery. It could explode and
cause serious injury.
. Your vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
For 2.0L turbo gasoline engine models:
The vehicle has 2 batteries, a main
battery and an auxiliary battery. The
engine cannot be started if either bat-
tery is discharged. First, apply the
following procedure to the main battery
to jump-start the engine.
If the engine does not start, apply the
procedure to the auxiliary battery. For
the position of the batteries, see “Engine
compartment check locations” (P.8-4)
or “Battery” (P.8-16).
. Use the special battery that is dedi-
cated for the Idling Stop System,
with enhanced charge-discharge ca-
pacity and life performance. Using
the non-special battery could cause
early deterioration of the battery
and/or malfunction of the Idling Stop System. For the special battery, it is
recommended to use Genuine
NISSAN parts. For more information,
it is recommended you contact an
INFINITI retailer.
. It may take some time until the Idling
Stop System activates when the
battery is replaced or the battery
terminal is disconnected for extended
periods and then reconnected.

6-16In case of emergency
Do not attempt to start the engine by
pushing.
CAUTION
.Automatic Transmission (AT) 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 vehi-
cle.
CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle fire.
. To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the
radiator cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc., take the following
steps:
1. Move the vehicle safely off the road, apply the parking brake and move the
shift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
3. If engine overheating is caused by climb- ing a long hill on a hot day, run the engine at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off the
engine.) Do not open the hood further
until no steam or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is
leaking or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling

Two-Wheel Drive (2WD) models
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 illustrated.
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 necessary
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.

7-4Appearance and care
Bright wheels (if so equipped)
The bright wheels use a different coating
process than typical aluminum alloy wheel
and they are not plated wheels. These
wheels are clear-coated and require the
following special cleaning. They should be
regularly washed with a soft sponge soaked
in a lot of water. After washing with water,
wipe clean with a dry, soft cloth and dry
completely. When there is chemical or tire
wax, or dirt such as an antifreeze agent on
the surface, wash them with water as soon
as possible.
CAUTION
.The surfaces of the wheels use a
different coating process than typical
aluminum alloy wheels. Do not use
aluminum alloy wheel cleaners or
abrasive cleaners to clean the wheels.
Using such cleaners could damage the
wheel surfaces.
. Do not use an automatic car wash if
the vehicle is equipped with bright
wheels. The wheel coating may be
damaged.
. Do not use a brush to wash the
wheels if the vehicle is equipped with
bright wheels. The wheel coating may be damaged.
CHROME PARTS
Clean chrome parts regularly with a non-
abrasive chrome polish to maintain the
finish.
TIRE DRESSING
INFINITI does not recommend the use of tire
dressings. Tire manufacturers apply a coat-
ing to the tires to help reduce discoloration
of the rubber. If a tire dressing is applied to
the tires, it may react with the coating and
form a compound. This compound may come
off the tire while driving and stain the vehicle
paint.
If you choose to use a tire dressing, take the
following precautions:
.
Use a water-based tire dressing. The
coating on the tire dissolves more easily
with an oil-based tire dressing.
. Apply a light coat of tire dressing to help
prevent it from entering the tire tread/
grooves (where it would be difficult to
remove).
. Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is
completely removed from the tire tread/
grooves. .
Allow the tire dressing to dry as recom-
mended by tire dressing manufacturer.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
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 shift
lever to P (Park).
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. Never connect or disconnect the
battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion 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 when-
ever 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
supported 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 warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
. Because the fuel lines are under high
pressure even when the engine is off,
it is recommended you visit an
INFINITI retailer for service of the fuel filter or fuel lines.
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 en-
gine oil and coolant. Improperly dis-
posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items which
are relatively easy for an owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-26).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and could
affect your warranty coverage. If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.
