LITHIUM-ION (Li-ion) BATTERY
AIR VENT

CAUTION

. Do not place objects over or into the

air vent. The Li-ion battery may
overheat and be damaged.

. Do not allow any liquid to get on or in

the air vent. It may cause a short
circuit and damage the Li-ion bat-
tery.

. Clean the air vent regularly to pre-

vent the Li-ion battery from over-

heating.

Regularly clean the air vent

with a dry

cloth to prevent the vent from being blocked.

AIR FRESHENERS

Most air fresheners use a solvent that could
affect the vehicle interior. If you use an air
freshener, take the following precautions:
. Hanging-type air fresheners can cause

permanent discoloration when they con-
tact vehicle interior surfaces. Place the
air freshener in a location that allows it
to hang free and not contact an interior
surface.

. Liquid-type air fresheners typically clip

on the vents. These products can cause
immediate damage and discoloration
when spilled on interior surfaces.

Carefully read and follow the manufac-
turer’s instructions before using air fresh-
eners.

MOONROOF SUNSHADE

The moonroof sunshade is made from a
suede material.
Clean the sunshade material as follows:

CAUTION

To help prevent damaging the sunshade
while cleaning:
. Do not rub the material with a cloth.

Doing so can damage the surface of
the material or can use a stain to
spread.

. Never use benzine, thinner or any

similar chemical to clean the suede.
This may discolor the sunshade and
damage the surface.

. Clean water based stains by patting

the surface with a clean soft cloth
dampened in warm water. Press a
clean dry cloth onto the surface to
remove as much dampness as possi-
ble and then let air dry.

. Clean oil based stains by patting the

surface with a clean soft cloth dam-
pened in warm water. Press a clean

WARNING

To avoid potential pedal interference
that may result in a collision, injury or
death:
. NEVER place a floor mat on top of

another floor mat in the driver front
position or install them upside down
or backwards.

. It is recommended that you use only

genuine INFINITI floor mats specifi-
cally designed for use in your vehicle
model and model year. See your
INFINITI retailer for more informa-
tion.

. Properly position the mats in the

floorwell using the floor mat posi-
tioning hook. See “Floor mat installa-
tion” (P.7-6).

. Make sure the floor mat does not

interfere with pedal operation.

. Periodically check the floor mats to

make sure they are properly installed.

. After cleaning the vehicle interior,

check the floor mats to make sure
they are properly installed.

The use of genuine INFINITI floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular cleaning
and replaced if they become excessively
worn.

Floor mat installation

Your vehicle is equipped with floor mat
positioning hook(s). The number and shape
of the floor mat positioning hook(s) for each
seating position varies depending on the
vehicle.
When installing genuine INFINITI floor mats,
follow the installation instructions provided
with the floor mat and the following:
1. Position the floor mat in the floorwell so

that the mat grommet holes are aligned
with the hook(s).

2. Secure the grommet holes into the hook

(s) and ensure that the floor mat is
properly positioned.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

3. Make sure the floor mat does not

interfere with pedal operation. With the
ignition in the OFF position and the shift
lever in the P (Park) position, fully apply
and release all pedals. The floor mat
must not interfere with pedal operation
or prevent the pedal from returning to its
normal position. It is recommended you
see an INFINITI retailer for details about
installing the floor mats in your vehicle.

MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION

. The accumulation of moisture-retaining

dirt and debris in body panel sections,
cavities, and other areas.

. Damage to paint and other protective

coatings caused by gravel and stone
chips or minor traffic accidents.

ENVIRONMENTAL FACTORS IN-
FLUENCE THE RATE OF COR-
ROSION

Moisture

Accumulation of sand, dirt and water on the
vehicle body underside can accelerate corro-
sion. Wet floor coverings will not dry
completely inside the vehicle, and should be
removed for drying to avoid floor panel
corrosion.

Relative humidity

Corrosion will be accelerated in areas of high
relative humidity, especially those areas
where the temperatures stay above freezing
where atmospheric pollution exists, or where
road salt is used.

Temperature

A temperature increase will accelerate the
rate of corrosion to those parts which are
not well ventilated.

Air pollution

Industrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use will accelerate the corrosion process.
Road salt will also accelerate the disintegra-
tion of paint surfaces.

TO PROTECT YOUR VEHICLE
FROM CORROSION

. Wash and wax your vehicle often to keep

the vehicle clean.

. Always check for minor damage to the

paint and repair it as soon as possible.

. Keep drain holes at the bottom of the

doors open to avoid water accumulation.

. Check the underbody for accumulation of

sand, dirt or salt. If present, wash with
water as soon as possible.

CAUTION

. NEVER remove dirt, sand or other

debris from the passenger compart-
ment by washing it out with a hose.
Remove dirt with a vacuum cleaner.

. Never allow water or other liquids to

come in contact with electronic com-
ponents inside the vehicle as this may
damage them.

Chemicals used for road surface deicing are
extremely corrosive. They accelerate corro-
sion and deterioration of underbody compo-
nents such as the exhaust system, fuel and
brake lines, brake cables, floor pan and
fenders.
In winter, the underbody must be cleaned
periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, it is recommended you consult an
INFINITI retailer.

CORROSION PROTECTION

-------------------------------------------------------------------------------------------------------------------------------------------------------------

8-2

Do-it-yourself

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

. This vehicle has high voltage DC and

AC systems as well as a 12-volt
system. DC and AC high voltage is
very dangerous and can cause severe
burns and electric shock that may
result in serious injury or death.

. Never touch, disassemble, remove or

replace the high voltage parts, har-
nesses and their connectors. High
voltage cables are orange. Touching,
disassembling, removing or replacing
those parts and harnesses can cause
severe burns or electric shock that
may result in serious injury or death.

. Never try to remove the service plug

located in the trunk room. The service
plug is used only when the vehicle is
serviced by trained technicians wear-
ing personal protection equipment
and is part of the high voltage
system. Touching the service plug
can cause severe burns or electric

shock that may result in serious injury
or death.

. The INFINITI Direct Response Hy-

brid

System uses high voltage up to

408 volts. The system can be hot
while and after starting. Be careful of
both the high voltage and the high
temperature. Obey the caution labels
attached to the vehicle.

. 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.

. The engine can start at any time

without warning when the hybrid
system is in the READY to drive
mode. If you must work with the
Hybrid System in the READY to drive
mode, keep your hands, clothing, hair
and tools away from fans, belts and
any other parts that can move.

. 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.

. 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.

. 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 the fuel tank and
battery.

CAUTION

. Do not work under the hood while the

engine is hot. Turn the hybrid system
off and wait until it cools down.

. Avoid direct contact with used en-

gine oil and coolant. Improperly dis-

MAINTENANCE PRECAUTIONS

-------------------------------------------------------------------------------------------------------------------------------------------------------------

posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.

. Never leave the engine or the trans-

mission related component harness
connector disconnected while the
ignition switch is in the ON position.

. Never connect or disconnect the

battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
