2013 INFINITI QX56 fuel system repair

2) Avoid hard acceleration or decelera-tion.
3) Avoid steep uphill grades.
4) If possible, reduce the amount of cargo being hauled or towed.
The malfunction indicator light may
stop blinking and remain on.
Have the vehicle inspected by an
INFINITI retailer. You do not need to
have your vehicle towed to the retailer.
CAUTION
Continued vehicle operation without having
the emission control system checked and
repaired as necessary could lead to poor
driveability, reduced fuel economy, and
possible damage to the emission control
system.
Security indicator light
The light blinks when the ignition switch is
in the ACC, OFF and LOCK position. This
function indicates the security system
equipped on the vehicle is operational.
If the security system is malfunctioning,
this light will remain on while the ignition switch is in the ON position. For additional
information, see
“Security systems” later
in this section.
SNOW mode indicator light
When selecting SNOW mode while the
engine is running, this light will illuminate.
(See “SNOW mode” in the“5. Starting and
driving” section.)
TOW mode indicator light
This light will illuminate when the TOW
MODE is selected while the engine is
running. (See “Tow mode” in the“5.
Starting and driving” section.)
Turn signal/hazard indicator
lights
The light flashes when the turn signal
switch lever or hazard switch is turned on.
Vehicle Dynamic Control (VDC)
off indicator light
The light comes on when the vehicle
dynamic control off switch is pushed to
OFF. This indicates that the vehicle dynamic
control system is not operating.
When the 4L position is selected with the
Four-Wheel Drive (4WD) shift switch, the
VDC system is disabled and the VDC off indicator light illuminates. (4WD models)

when the ignition switch is turned to the
OFF position with the fog lights on while
the headlight switch is in the AUTO
position (if so equipped).

MOST COMMON FACTORS CONTRI-
BUTING 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 INFLU-
ENCE THE RATE OF CORROSION
Moisture
Accumulation of sand, dirt and water on
the vehicle body underside can accelerate
corrosion. 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 ex-
ists, 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 disinte-
gration 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 accumula-
tion.
. 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 compartment 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 compo-
nents inside the vehicle as this may
damage them.
Chemicals used for road surface deicing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components 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, consult an INFINITI retailer.
Appearance and care7-7
CORROSION PROTECTION

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” in the“7. Appear-
ance and care ”section.
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. 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.
. On gasoline engine models, the fuel
filter or fuel lines should be serviced by
an INFINITI retailer because the fuel lines
