LANE CAMERA UNIT MAINTENANCE
The lane camera units1for the LDW/LDP
system is located inside the map light cover. To
keep the proper operation of the LDW/LDP
systems and prevent a system malfunction, be
sure to observe the following:
c Always keep the windshield clean.
c Do not attach a sticker (including transpar-
ent material) or install an accessory near the
camera unit.
c Do not place reflective materials, such as
white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit's capability of
detecting the lane markers. c
Do not strike or damage the areas around
the camera unit. Do not touch the camera
lens or remove the screw located on the
camera unit. If the camera unit is damaged
due to an accident, contact an INFINITI re-
tailer.
PRECAUTIONS ON CRUISE CONTROL
cIf the cruise control system malfunctions, it
will cancel automatically. The SET indicator
on the dot matrix crystal display will then
blink to warn the driver.
c If the engine coolant temperature becomes
excessively high, the cruise control system
will be canceled automatically.
c If the SET indicator blinks, turn the cruise
control main switch off and have the system
checked by your INFINITI retailer.
c The SET indicator may sometimes blink
when the cruise control main switch is
turned ON while pushing the
RESUME/ACCELERATE, SET/COAST or CAN-
CEL switch. To properly set the cruise control
system, perform the steps below in the order
indicated.
WARNING
Do not use the cruise control when driving un-
der the following conditions:
cwhen it is not possible to keep the vehicle at
a set speed
c in heavy traffic or in traffic that varies in
speed
c on winding or hilly roads

Sensor maintenance
The sensor for the ICC systemsAis located
below the front bumper.
To keep the ICC system operating properly, be
sure to observe the following:
c Always keep the sensor clean. Wipe with a
soft cloth carefully so as not to damage the
sensor.
c Do not strike or damage the areas around
the sensor. Do not touch or remove the
screw located on the sensor. Doing so could
cause failure or malfunction. If the sensor is
damaged due to an accident, contact an
INFINITI retailer.
c Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.
CONVENTIONAL (FIXED SPEED) CRUISE
CONTROL MODE
This mode allows driving at a speed between 25
to 89 MPH (40 to 144 km/h) without keeping
your foot on the accelerator pedal.
WARNING
cIn the conventional (fixed speed) cruise con-
trol mode, a warning chime does not sound
to warn you if you are too close to the vehicle
ahead, as neither the presence of the vehicle
ahead nor the vehicle-to-vehicle distance is
detected.
c Pay special attention to the distance be-
tween your vehicle and the vehicle ahead of
you or a collision could occur.
c Always confirm the setting in the Intelligent
Cruise Control system display.
c Do not use the conventional (fixed speed)
cruise control mode when driving under the
following conditions:
± when it is not possible to keep the vehicle at a set speed
± in heavy traffic or in traffic that varies in speed
± on winding or hilly roads
± on slippery roads (rain, snow, ice, etc.)
± in very windy areas
c Doing so could cause a loss of vehicle control
and result in an accident.

ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
cThe Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent ac-
cidents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on nor-
mal surfaces even with ABS. Stopping dis-
tances may also be longer on rough, gravel
or snow covered roads, or if you are using
tire chains. Always maintain a safe distance
from the vehicle in front of you. Ultimately,
the driver is responsible for safety.
c Tire type and condition may also affect brak-
ing effectiveness.
± When replacing tires, install the specified size of tires on all four wheels.
± When installing a spare tire, make sure that it is the proper size and type as speci-
fied on the Tire and Loading Information
label. See ªTIRE AND LOADING INFORMA-
TION LABELº in the ª9. Technical and con-
sumer informationº section of this
manual. ± For detailed information, see ªWHEELS
AND TIRESº in the ª8. Maintenance and
do-it-yourselfº section of this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle at a low speed in
forward or reverse. When the self-test occurs,
you may hear a ªclunkº noise and/or feel a
pulsation in the brake pedal. This is normal and
does not indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI retailer.

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole or use the Intelligent Key system.
ANTI-FREEZE
In the winter when it is anticipated that the
outside temperature will drop below 32ÉF (0ÉC),
check antifreeze to assure proper winter protec-
tion. For additional information, see ªENGINE
COOLING SYSTEMº in the ª8. Maintenance and
do-it-yourselfº section.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, see ªBATTERYº in the ª8. Mainte-
nance and do-it-yourselfº section.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see ªENGINE COOLING SYS-
TEMº in the ª8. Maintenance and do-it-yourselfº
section.
TIRE EQUIPMENT
SUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. If you operate your vehicle on snowy or
icy roads, INFINITI recommends the use of MUD
& SNOW or ALL SEASON tires on all four wheels.
Consult an INFINITI retailer for the tire type,
size, speed rating and availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
installing studded tires.
Skid and traction capabilities of studded snow
tires, on wet or dry surfaces, may be poorer than
that of non-studded snow tires.
Tire chains may be used. For details, see ªTIRE
CHAINSº in the ª8. Maintenance and do-it-
yourselfº section of this manual.
All-Wheel Drive (AWD) model
If you install snow tires, they must also be the
same size, brand, construction and tread pat-
tern on all four wheels.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
cA scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
c A sturdy, flat board to be placed under the
jack to give it firm support.
c A shovel to dig the vehicle out of snowdrifts.
c Extra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
cWet ice (32ÉF, 0ÉC and freezing rain), very
cold snow or ice can be slick and very hard to
drive on. The vehicle will have much less
traction or ªgripº under these conditions.
Try to avoid driving on wet ice until the road
is salted or sanded.
c Whatever the condition, drive with caution.
Accelerate and slow down with care. If accel-
erating or downshifting too fast, the drive
wheels will lose even more traction.

Installing the spare tire
The spare tire is designed for emergency use.
(See specific instructions under the heading
ªWHEELS AND TIRESº in the ª8. Maintenance
and do-it-yourselfº section.)
1. Clean any mud or dirt from the surfacebetween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight. Check that all
the wheel nuts contact the wheel surface
horizontally.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the se-
quence as illustrated (
s1,s2,s3,s4,s5),
more than 2 times, until they are tight. 4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts se-
curely in the sequence as illustrated.
Lower the vehicle completely.
WARNING
cIncorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become
loose or come off. This could cause an
accident.
c Do not use oil or grease on the wheel studs or
nuts. This could cause the nuts to become
loose.
c Retighten the wheel nuts when the vehicle
has been driven for 600 miles (1,000 km)
(also in cases of a flat tire, etc.). c
As soon as possible, tighten the wheel nuts
to the specified torque with a torque wrench.
Wheel nut tightening torque: 80 ft-lb (108 N´m)
The wheel nuts must be kept tightened to speci-
fication at all times. It is recommended that
wheel nuts be tightened to specifications at
each lubrication interval.
c Adjust tire pressure to the COLD pressure.
COLD pressure:
After the vehicle has been parked for three
hours or more or driven less than 1 mile
(1.6 km).
COLD tire pressures are shown on the Tire
and Loading Information label affixed to the
driver side center pillar.
After adjusting tire pressure to the COLD tire
pressure, the display of the tire pressure infor-
mation may show higher pressure than the
COLD tire pressure after the vehicle has been
driven more than 1 mile (1.6 km). This is be-
cause the tire pressurizes as the tire tempera-
ture rises. This does not indicate a system
malfunction.

5. Securely store the flat tire and jackingequipment in the vehicle.
6. Place the spare tire cover and the trunk floor carpeting over the damaged tire.
7. Close the trunk.
WARNING
c Always make sure that the spare tire and
jacking equipment are properly secured af-
ter use. Such items can become dangerous
projectiles in an accident or sudden stop. c
The T-type spare tire and small size spare
tire are designed for emergency use. See
specific instructions under the heading
ªWHEELS AND TIRESº in the ª8. Maintenance
and do-it-yourselfº section.

Please see your Warranty Information Booklet
or Roadside Assistance I.D. Card for the toll-free
number to call (U.S.) or Warranty Information
Booklet (Canada). To start your engine with a booster battery, the
instructions and precautions below must be
followed.
WARNING
c
If done incorrectly, jump starting can lead to
a battery explosion, resulting in severe in-
jury or death. It could also damage your
vehicle.
c Explosive hydrogen gas is always present in
the vicinity of the battery. Keep all sparks
and flames away from the battery.
c Do not allow battery fluid to come into con-
tact with eyes, skin, clothing or painted sur-
faces. Battery fluid is a corrosive sulfuric
acid solution which can cause severe burns.
If the fluid should come into contact with
anything, immediately flush the contacted
area with water.
c Keep the battery out of the reach of children.
c The booster battery must be rated at 12
volts. Use of an improperly rated battery can
damage your vehicle.

Your new INFINITI has been designed to have
minimum maintenance requirements with long
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your IN-
FINITI's fine mechanical condition, as well as its
emission and engine performance.
It is the owner's responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives the proper
maintenance. You are a vital link in the mainte-
nance chain.
SCHEDULED MAINTENANCE
For your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your ªINFINITI Service and
Maintenance Guideº. You must refer to that
guide to ensure that necessary maintenance is
performed on your INFINITI at regular intervals.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-to-
day operation. They are essential for propervehicle operation. It is your responsibility to
perform these procedures regularly as pre-
scribed.
Performing general maintenance checks re-
quires minimal mechanical skill and only a few
general automotive tools.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer,
an INFINITI retailer.
WHERE TO GO FOR SERVICE
If maintenance service is required or your ve-
hicle appears to malfunction, have the systems
checked and serviced by an INFINITI retailer.
INFINITI technicians are well-trained specialists
and are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-retailer information systems. They
are completely qualified to work on INFINITI
vehicles
beforework begins.
You can be confident that an INFINITI retailer's
service department performs the best job to
meet the maintenance requirements on your
vehicle Ð in a reliable and economical way. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have an
INFINITI retailer do it promptly. In addition, you
should notify an INFINITI retailer if you think
that repairs are required.
When performing any checks or maintenance
work, see ªMAINTENANCE PRECAUTIONSº later
in this section.EXPLANATION OF MAINTENANCE
ITEMS
Additional information on the following items
with ª*º is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood:
Check that all doors
and the engine hood operate properly. Also
