fraying, wear or damage.
Seats:Check seat position controls such as
seat adjusters, seatback recliners, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washers operate properly
and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: Check the fluid level in each cell. It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1.
Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake and clutch fluid levels*: Make sure
that the brake and clutch fluid levels are
between the MAX and MIN lines on the
reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belt*: Make sure that the
drive belt is not frayed, worn, cracked or
oily. Engine oil level*:
Check the level after
parking the vehicle on a level surface and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3) for exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level with the engine off. Check
the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.

Underbody:The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust.
It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see “Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir. 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. For manual transmission mod-
els, move the shift lever to N (Neutral).
For automatic transmission models,
move the shift 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 ignition switch is in the ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected 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
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 auto-
matic 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 disconnect the negative
battery cable before working near the
fan.

TIRE CHAINS
Use of tire chains may be prohibited
according to location. Check the local laws
before installing tire chains. When instal-
ling tire chains, make sure they are the
proper size for the tires on your vehicle and
are installed according to the chain man-
ufacturer’s suggestions. Use only SAE
Class S chains. Class“S”chains are used
on vehicles with restricted tire to vehicle
clearance. Vehicles that can use Class “S”
chains are designed to meet the SAE
standard minimum clearances between
the tire and the closest vehicle suspension
or body component required to accommo-
date the use of a winter traction device (tire
chains or cables). The minimum clearances
are determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the
tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling and performance may be adversely af-
fected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.
CHANGING WHEELS AND TIRES
Tire rotation
Tires cannot be rotated on this
vehicle because the front tires are a
different size than the rear tires.
A pin is on the front brake rotor to
prevent the rear wheels from being
installed in place of the front wheels.
The spare tire can be installed in
place of the front and rear wheels.
When installing the spare tire in the
front wheel, the hole in the spare tire
wheel must be aligned with the pin
on the brake rotor.
WARNING
.
Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.
