When the low tire pressure warning light
illuminates, you should stop and adjust the
tire pressure of all 4 tires to the recom-
mended COLD tire pressure shown on the
Tire and Loading Information label located
in the driver’s door opening. The low tire
pressure warning light does not automati-
cally turn off when the tire pressure is ad-
justed. After the tire is inflated to the rec-
ommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h)
to activate the TPMS and turn off the low
tire pressure warning light. Use a tire pres-
sure gauge to check the tire pressure.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and in the “In case of emergency”
section.
TPMS malfunction:
If the TPMS is not functioning properly, the low
tire pressure warning light will flash for approxi-
mately 1 minute when the ignition switch is
turned ON. The light will remain on after the 1
minute. Have the system checked by an INFINITI
dealer.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and “Tire pressure” in the “Main-
tenance and do-it-yourself” section.WARNING
●If the light does not illuminate with the
ignition switch turned ON, have the ve-
hicle checked by an INFINITI dealer as
soon as possible.
● If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and in-
crease the likelihood of tire failure. Se-
rious vehicle damage could occur and
may lead to an accident and could re-
sult in serious personal injury. Check
the tire pressure for all four tires. Adjust
the tire pressure to the recommended
COLD tire pressure shown on the Tire
and Loading Information label located
in the driver’s door opening to turn the
low tire pressure warning light OFF. If
the light still comes on while driving
after adjusting the tire pressure, a tire
may be flat. If you have a flat tire, re-
place it with a spare tire as soon as
possible. ●
When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI dealer as soon as
possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
CAUTION
● The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
● If the vehicle is being driven at speeds
of less than 16 MPH (25 km/h) , the
TPMS may not operate correctly.
● Be sure to install the specified size of
tires to the 4 wheels correctly.

Your vehicle has two types of security systems:● Vehicle security system
● INFINITI Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual and
audible alarm signals if someone opens the doors
or lift gate when the system is armed. It is not,
however, a motion detection type system that
activates when a vehicle is moved or when a
vibration occurs.
The system helps deter vehicle theft but cannot
prevent it, nor can it prevent the theft of interior or
exterior vehicle components in all situations. Al- ways secure your vehicle even if parking for a
brief period. Never leave your Intelligent Key in
the vehicle, and always lock the vehicle when
unattended. Be aware of your surroundings, and
park in secure, well-lit areas whenever possible.
Many devices offering additional protection, such
as component locks, identification markers, and
tracking systems, are available at auto supply
stores and specialty shops. Your INFINITI dealer
may also offer such equipment. Check with your
insurance company to see if you may be eligible
for discounts for various theft protection features.
How to arm the vehicle security
system
1. Close all windows.
(The system can be
armed even if the windows are open.)
2. Place the ignition switch in the LOCK posi- tion and remove the key.
3. Close all doors and the hood. Lock all doors. The doors can be locked with:
● the power door lock switch (if the door is
opened, locked and then closed) .
● the mechanical key.
● any request switch.
● the Intelligent Key. Intelligent Key operation:
●
Push the
button. All doors lock.
The hazard lights flash twice and the horn
beeps once to indicate all doors are
locked.
● When the
button is pushed with
all doors locked, the hazard lights flash
twice and the horn beeps once as a re-
minder that the doors are already locked.
The horn may or may not beep. Refer to
“Comfort & Convenience settings” in the
“Monitor, climate, audio, phone and voice
recognition systems” section.
4. Confirm that the
indicator light comes
on. The
light stays on for about 30
seconds. The vehicle security system is now
pre-armed. After about 30 seconds the ve-
hicle security system automatically shifts
into the armed phase. The
light begins
to flash once every 3 seconds. If, during the
30-second pre-arm time period, the driver’s
door is unlocked by the mechanical key, a
request switch, the Intelligent Key or if the
ignition switch is placed in the ACC or ON
position, the system will not arm.

●If the key is turned slowly when locking
the driver’s door, the system may not
arm. Furthermore, if the key is turned
beyond the vertical position toward the
unlock position to remove the key, the
system may be disarmed when the key
is removed. If the indicator light fails to
glow for 30 seconds, unlock the door
once and lock it again.
● Even when the driver and/or passen-
gers are in the vehicle, the system will
arm with all doors closed and locked
with the ignition switch in the OFF po-
sition.
Vehicle security system activation
The vehicle security system will give the following
alarm:
● The headlights blink and the horn sounds
intermittently.
● The alarm automatically turns off after ap-
proximately 50 seconds. However, the alarm
reactivates if the vehicle is tampered with
again. The alarm can be shut off by unlocking
the driver’s door with the mechanical key, or
by pressing the
button on the Intelli-
gent Key. The alarm is activated by:
● opening a door without using the mechani-
cal key or Intelligent Key (even if the door is
unlocked by using the inside lock knob or the
power door lock switch) .
● opening the hood.
How to stop an activated alarm
The alarm stops only by unlocking the driver’s
door with the mechanical key, a request switch or
by pressing the
button on the Intelligent
Key.
INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will not
allow the engine to start without the use of a
registered INFINITI Vehicle Immobilizer System
key.
If the engine fails to start using a registered
INFINITI Vehicle Immobilizer System key (for ex-
ample, when interference is caused by another
INFINITI Vehicle Immobilizer System key, an au-
tomated toll road device or automatic payment
device on the key ring) , restart the engine using
the following procedures:
1. Leave the ignition switch in the ON position for approximately 5 seconds. 2. Place the ignition switch in the OFF or
LOCK position, and wait approximately 10
seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the interference)
separate from the registered INFINITI Ve-
hicle Immobilizer System key.

WARNING
Do not push start this vehicle. The three-
way catalyst may be damaged.
CAUTION
Automatic transmission models cannot
be push-started or tow-started. Attempt-
ing to do so may cause transmission
damage.
WARNING
●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 or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant reser-
voir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
● Do not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading and
the illumination of the engine oil pressure/engine
coolant temperature high indicator light) , 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 selector
to P (Park) .
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. 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,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
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
fan can start at any time.

In order to maintain the appearance of your ve-
hicle, it is important to take proper care of it.
To protect the paint surfaces, please wash your
vehicle as soon as you can:● after a rainfall to prevent possible damage
from acid rain.
● after driving on coastal roads.
● when contaminants such as soot, bird drop-
pings, tree sap, metal particles or bugs get
on the paint surface.
● when dust or mud builds up on the surface.
Whenever possible, store or park your vehicle
inside a garage or in a covered area.
When it is necessary to park outside, park in a
shady area or protect the vehicle with a body
cover.
Be careful not to scratch the paint surface
when putting on or removing the body
cover.
WASHING
Wash dirt off with a wet sponge and plenty of
water. Clean the vehicle thoroughly using a mild
soap, a special vehicle soap or general purpose
dishwashing liquid mixed with clean, lukewarm
(never hot) water.
CAUTION
● Do not use car washes that use acid in
the detergent. Some car washes, espe-
cially brushless ones, use some acid for
cleaning. The acid may react with some
plastic vehicle components, causing
them to crack. This could affect their
appearance, and also could cause them
not to function properly. Always check
with your car wash to confirm that acid
is not used.
● Do not wash the vehicle with strong
household soap, strong chemical deter-
gents, gasoline or solvents.
● Do not wash the vehicle in direct sun-
light or while the vehicle body is hot, as
the surface may become water-spotted.
● Avoid using tight-napped or rough
cloths, such as washing mitts. Care
must be taken when removing
caked-on dirt or other foreign sub-
stances so the paint surface is not
scratched or damaged.
Rinse the vehicle thoroughly with plenty of clean
water.
Inside flanges, seams and folds on the doors,
hatches and hood are particularly vulnerable to the effects of road salt. Therefore, these areas
must be cleaned regularly. Take care that the
drain holes in the lower edge of the door are
open. Spray water under the body and in the
wheel wells to loosen the dirt and wash away
road salt.
A damp chamois can be used to dry the vehicle to
avoid water spots.
WAXING
Regular waxing protects the paint surface and
helps retain new vehicle appearance. Polishing is
recommended to remove built-up wax residue
and to avoid a weathered appearance before
re-applying wax.
An INFINITI dealer can assist you in choosing the
proper product.
● Wax your vehicle only after a thorough wash-
ing. Follow the instructions supplied with the
wax.
● Do not use a wax containing any abrasives,
cutting compounds or cleaners that may
damage the vehicle finish.
Machine compounding or aggressive polishing
on a base coat/clear coat paint finish may dull the
finish or leave swirl marks.

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 INFINI-
TI’s good 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 proper
maintenance. You are a vital link in the mainte-
nance chain.
Scheduled maintenance
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “INFINITI Service and Maintenance
Guide”. 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 op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
maintenance procedures regularly as prescribed.Performing general maintenance checks requires
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by you,
a qualified technician, or, if you prefer, an INFINITI
dealer.
Where to go for service
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected by an INFINITI dealer.
INFINITI technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-dealership training programs. They
are completely qualified to work on INFINITI ve-
hicles
before they work on your vehicle, rather
than after they have worked on it.
You can be confident that an INFINITI dealer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
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
smells, be sure to check for the cause or have an
INFINITI dealer do it promptly. In addition, you
should notify an INFINITI dealer if you think that
repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with“*”isfound 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 the doors
and engine hood operate properly. Also ensure
that all latches lock securely. Lubricate hinges,
latches, latch pins, rollers and links as necessary.
Make sure that the secondary latch keeps the
hood from opening when the primary latch is
released.
