can be driven on a flat tire depends on
outside temperature, vehicle load,
road conditions and other factors.
–If you detect any unusual sounds or
vibrations while driving with a punc-
tured run-flat tire, pull off the road to
a safe location and stop the vehicle as
soon as possible. The tire may be se-
riously damaged and need to be re-
placed.
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•If you used Emergency Tire Sealant to
repair a minor tire puncture, the TPMS
sensor should be checked when repair-
ing or replacing the tire (for models
equipped with the emergency tire punc-
ture repair kit). It is recommended you
visit an INFINITI retailer for this service.
•INFINITI recommends using only
INFINITI Genuine Emergency Tire Seal-
ant provided with your vehicle. Other
tire sealants may damage the valve stem
seal which can cause the tire to lose air
pressure (for models equipped with the
emergency tire puncture repair kit).
CAUTION
•The TPMS may not function properly
when the wheels are equipped with
snow chains or the wheels are buried in
snow.
•Do not place metallized film or any metal
parts (antenna, etc.) on the windows.
This may cause poor reception of the
signals from the tire pressure sensors,
and the TPMS will not function
properly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pres-
sure suitable for the operating situation (see
"Wheels and tires"). Note that the correct tire
pressure for the current operating situation
must first be taught-in to the tire pressure
monitor (see "Restarting TPMS" later in this
section).
If there is a substantial loss of pressure, the
warning threshold for the warning message
is aligned to the reference values taught-in.
Restart the tire pressure monitor after ad-
justing to the cold tire pressure. The current
pressures are saved as new reference values.
This will ensure that a warning message will
only appear if the tire pressure drops signifi-
cantly.The tire pressure monitor does not warn you
of an incorrectly set tire pressure.
TPMS is not able to warn you of a sudden
loss of pressure, e. g. if the tire is penetrated
by a foreign object. In the event of a sudden
loss of pressure, bring the vehicle to a halt by
braking carefully. Avoid abrupt steering ma-
neuvers.
TPMS has a yellow warning light in the com-
bination meter for indicating a pressure loss
or malfunction. Depending on how the warn-
ing light flashes or lights up, a tire pressure
that is too low or a malfunction in TPMS is
indicated:
•If the warning light is lit continuously, the
tire pressure on one or more tires is signifi-
cantly too low. TPMS is not malfunction-
ing.
•If the warning light flashes for around a
minute and then remains lit constantly, the
TPMS is malfunctioning.
In addition to the warning light, a message
appears in the vehicle information display.
Observe the information on display mes-
sages (see "Safety systems"
It may take up to ten minutes for a malfunc-
tion of the tire pressure monitor to be indi-
cated. A malfunction will be indicated by the

2. Maintain a firm grip on the steering wheel
with both hands and try to hold a straight
course.
3. When appropriate, slowly release the ac-
celerator pedal to gradually slow the ve-
hicle.
4. Gradually steer the vehicle to a safe loca-
tion off the road and away from traffic if
possible.
5. Lightly apply the brake pedal to gradually
stop the vehicle.
6. Turn on the hazard warning flashers and
contact a roadside emergency service to
change the tire. For additional informa-
tion, refer to "Flat tire".
DRINKING ALCOHOL/DRUGS
AND DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood of
being involved in an accident injuring your-
self and others. Additionally, if you are in-
jured in an accident, alcohol can increase
the severity of the injury.INFINITI is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
accidents. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people dif-
ferently and most people underestimate the
effects of alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs). Don’t
drive if your ability to operate your vehicle is
impaired by alcohol, drugs, or some other
physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is mainly
designed for leisure use, unlike a conventional
off-road vehicle.
Remember that 2–wheel drive vehicles are
less capable than all-wheel drive (AWD)
models for rough road driving and extrication
when stuck in deep snow or mud, or the like.Please observe the following precautions:
WARNING
•Spinning the front wheels on slippery
surfaces may cause the AWD warning
message to display and the AWD system
to automatically switch from the AWD
to 2WD mode. This could reduce the
traction. Be especially careful when
towing a trailer. (AWD models)
•Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle should
be seated with their seat belt fastened.
This will keep you and your passengers
in position when driving over rough ter-
rain.
•Do not drive across steep slopes. Instead
drive either straight up or straight down
the slopes. Off-road vehicles can tip
over sideways much more easily than
they can forward or backward.
•Many hills are too steep for any vehicle.
If you drive up them, you may stall. If you
drive down them, you may not be able to
control your speed. If you drive across
them, you may roll over.

5-26Starting and driving

In addition to the vehicle load, the driving
distance possible depends upon:
•Vehicle speed.
•Road condition.
•Outside temperature.
The driving distance possible in run-flat mode
may be reduced by extreme driving
conditions/maneuvers, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat mode
is counted from the moment the tire pressure
loss warning appears in the vehicle informa-
tion display.
You must not exceed a maximum speed of
50 MPH (80 km/h).
When replacing one or all tires, observe the
following specifications for your vehicle's tires:
•Size
•Type
•Run-flat mark
If a tire has gone flat and cannot be replaced
with a run flat tire, a standard tire may be
used as a temporary measure. Make sure that
you use the proper size and type (summer or
winter tire).
WARNING
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneu-
vers, and driving over obstacles (curbs, pot
holes, off road). This applies in particular to
a laden vehicle.
Stop driving in emergency mode if:
•You hear banging noises.
•The vehicle starts to shake.
•You see smoke and smell rubber.
•VDC is intervening constantly.
•There are tears in the sidewalls of the
tire.
After driving in emergency mode, have the
wheel rims checked with regard to their
further use. It is recommended you visit an
INFINITI retailer for this service. The faulty
tire must be replaced.
REMOVING AND FITTING
WHEELS
NOTE
A spare wheel is not provided with your ve-
hicle.
Blocking the wheels
WARNING
Make sure to block the appropriate wheel
to prevent the vehicle from moving, which
may cause personal injury.
Place suitable blocks
1in front of and be-
hind the wheel diagonally opposite the flat
tire
Ato prevent the vehicle from moving
when it is on the jack.

3. Align the center of both the jack head2and the notches at the jack-up point3as
shown.
4. Fit the groove of the jack head between
the two notches as shown.5. Loosen each wheel bolt by one or two
turns counterclockwise with the wheel
wrench.
Do not remove the wheel bolts until the
tire is off the ground.
Models with wheel lock bolts (if equipped) :
If the wheel is equipped with a wheel lock
bolt, insert the wheel lock key
1and
loosen it as previously described.
The wheel lock bolt can only be removed
with the wheel lock key. A key number is
necessary if you need to duplicate the
wheel lock key.Record the key number as shown on the
key code card on the “Security informa-
tion” page at the end of this manual and
keep it in a safe place, not in the vehicle. If
you lose the wheel lock key, it is recom-
mended you see your INFINITI retailer for
a duplicate with the original wheel lock
key code.
Make sure to keep the lock key in the
vehicle. Otherwise, wheels cannot be re-
moved and the service cannot be per-
formed.

When towing your vehicle, all jurisdictions and
local regulations for towing must be followed.
Incorrect towing equipment could damage
your vehicle. Towing instructions are available
from an INFINITI retailer. Local service opera-
tors are generally familiar with the applicable
laws and procedures for towing. To assure
proper towing and to prevent accidental dam-
age to your vehicle, INFINITI recommends
having a service operator tow your vehicle. It is
advisable to have the service operator carefully
read the following precautions.
WARNING
•Never ride in a vehicle that is being
towed.
•Never get under your vehicle after it has
been lifted by a tow truck.
CAUTION
•When towing, make sure that the trans-
mission, axles, steering system and
powertrain are in working condition. If
any of these conditions apply, dollies or
a flatbed tow truck must be used.
•Always attach safety chains before
towing.
TOWING RECOMMENDED BY
INFINITI
INFINITI recommends towing your vehicle
based upon the type of drivetrain. Please re-
fer to the diagrams in this section to ensure
that your vehicle is properly towed.

Two-Wheel Drive (FWD) models
CAUTION
NEVER tow automatic transmission (DCT)
models with the front wheels on the
ground or with all four wheels on the
ground (forwards or backwards), as this
may cause serious and expensive damage
to the transmission. If it is necessary to tow
the vehicle with the rear wheels raised, al-
ways use towing dollies under the front
wheels.
Four-Wheel Drive (4WD) models
INFINITI recommends that towing dollies be
used under the front or rear wheels when
towing your vehicle or the vehicle be placed
on a flatbed tow truck as illustrated.
CAUTION
Never tow 4WD models with any of the
wheels on the ground. Doing so will cause
serious and expensive damage to the
drivetrain.
Vehicle recovery (freeing a stuck
vehicle)
WARNING
To avoid vehicle damage, serious personal
injury or death when recovering a stuck ve-
hicle:
•Contact a professional towing service to
recover the vehicle if you have any ques-
tions regarding the recovery procedure.
•Tow chains or cables must be attached
only to main structural members of the
vehicle.
•Do not use the vehicle tie downs to tow
or free a stuck vehicle.
•Only use devices specifically designed
for vehicle recovery and follow the
manufacturer's instructions.
•Always pull the recovery device straight
out from the front of the vehicle. Never
pull at an angle.
•Route recovery devices so they do not
touch any part of the vehicle except the
attachment point.

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self 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 mov-
ing. Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the
engine is hot. Always turn off the engine
and wait until it cools down.
•If you must work with the engine run-
ning, 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 any jewelry, such as
rings, watches, etc. before working 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 by a jack.
•Keep smoking materials, flame and
sparks away from fuel and the battery.
•Never connect or disconnect either the
battery or any transistorized compo-
nent connector while the ignition switch
is in the ON position.
•On gasoline engine models with the
Multiport Fuel Injection system, the fuel
filter and fuel lines should be serviced by
an INFINITI retailer or qualified work-
shop because the fuel lines are under
high pressure even when the engine is
turned off.
•Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch 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.
•Always wear eye protection whenever
you work on your vehicle.
•Never leave the engine or the transmis-
sion related component harness connec-
tor disconnected while the ignition
switch is in the ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle
fluids can hurt the environment. Always
conform to local regulations for disposal
of vehicle fluids.

MAINTENANCE FREE BATTERY
For a maintenance free battery it is not re-
quired to check the fluid level. However,
INFINITI recommends to visually check the
status of the green indicator
A(if so
equipped) periodically. If it is not visible, re-
place the battery as soon as possible.
MODELS WITH IDLE
STOP/START SYSTEM
•Ensure that the battery fitted is the special
battery that is enhanced with regard to the
charge-discharge capacity and life perfor-
mance. Avoid using any other battery for
the Idle Stop/Start System, as this may
cause early deterioration of the battery or
a malfunction of the Idle Stop/Start Sys-
tem. It is recommended that a Genuine
INFINITI battery is fitted. For more infor-
mation, it is recommended that you con-
tact an INFINITI retailer.
•If the battery terminal is disconnected (for
battery replacement, etc.) and then recon-
nected, there may be some delay before
the Stop/Start System reactivates.
BATTERY REPLACEMENT
It is recommended that a Genuine INFINITI
battery is fitted. It is recommended that you
visit an INFINITI retailer for this service.

name molding that is higher or deeper than
the same molding on the other sidewall of the
tire, or (2) the outward facing sidewall of an
asymmetrical tire that has a particular side
that must always face outward when
mounted on a vehicle.
TYPES OF TIRES
WARNING
•When changing or replacing tires, be
sure all four tires are of the same type
(i.e, summer, all season or snow) and
construction. An INFINITI retailer may
be able to help you with information
about tire type, size, speed rating and
availability.
•Replacement tires may have a lower
speed rating than the factory equipped
tires, and they may not match the po-
tential maximum vehicle speed. Never
exceed the maximum speed rating of the
tire.
•Always use tires of the same type, size,
brand, construction and tread pattern
on all four wheels. Failure to do so may
result in a circumference difference be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunctionresulting in personal injury or death, ex-
cessive tire wear and may damage the
transmission, transfer case and differ-
ential gears.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation“ (Canada) in the Warranty In-
formation Booklet.
CAUTION
ONLY use spare tires specified for the
model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
that you visit an INFINITI retailer for this
service.
All season tires
INFINITI specifies all season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
season tires are identified by ALL SEASON
and/or M&S on the tire sidewall. Snow tires
have better snow traction than all seasontires and may be more appropriate in some
areas.
Summer tires
INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is sub-
stantially reduced in snow and ice. Summer
tires do not have the tire traction rating M&S
on the tire sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, INFINITI recommends the use
of snow or all season tires on all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of
the tire. If you install snow tires, they must be
the same size, brand, construction and tread
pattern on all four wheels.
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
