Tire Pressure Monitoring System
warning messages
If the tire pressure monitor detects a pressure
loss in one or more tires, a warning message
is shown in the vehicle information display
and the yellow tire pressure monitor warning
light comes on.
•If the [Please Correct Tire Pressure] (yel-
low) message appears in the vehicle infor-
mation display, the tire pressure in at least
one tire is too low and must be corrected
at the next opportunity. If the system de-
tects that new sensors have been fitted
(IDs do not match those stored, and the
pressure is not feasible, or is less than 14%
under the norm then the [Please Correct
Tire Pressure] message will be displayed in
white.
•If the [Check Tires] (red) message appears
in the vehicle information display, the tire
pressure in one or more tires has dropped
significantly and the tires must be checked.
•If the [Warning Tire Malfunction] (red)
message appears in the vehicle informa-
tion display, the tire pressure in one or
more tires has dropped suddenly and the
tires must be checked.
•If the [Tire Press. Sensor(s) Missing] mes-
sage appears in the vehicle information
display, one or more sensors are missing or
cannot be detected. This could be the re-
sult of fitting a replacement wheel/tire.
Observe the instructions and safety notes in
the display messages in the vehicle informa-
tion display.
If the wheel positions on the vehicle are inter-
changed, the tire pressures may be displayed
for the wrong positions for a short time. After
a few minutes of driving, this is rectified and
the tire pressures are displayed for the cor-
rect positions.
Restarting TPMS
To keep the TPMS functioning properly, the
restart operation must be performed in the
following cases:
•When the tire pressure is adjusted
•When a tire or a wheel is replaced
•When the tires are rotated
When you restart the tire pressure monitor,
all existing warning messages are deleted
and the warning lights go out. The monitor
uses the currently set tire pressures as the
reference values for monitoring. In mostcases, the tire pressure monitor will auto-
matically detect the new reference values af-
ter you have changed the tire pressure. How-
ever, you can also define reference values
manually as described here. The tire pressure
monitor then monitors the new tire pressure
values.
Perform the following procedures to restart
the TPMS.
NOTE
Before restarting, make sure that the tire
pressures are set properly on all four tires for
the respective operating conditions. The
recommended tire pressures can be found in
the tire pressure placard on the driver' door
pillar.
1. Make sure that the ignition switch is in the
ON position.
2. Press the
orbutton on the
steering wheel to select the [Serv.] menu.
3. Press the
orbutton to select
[Tire Pressure].
4. Press to confirm.
The vehicle information display shows the
current tire pressure for each tire or the
[Tire pressures will be displayed after
driving a few minutes] message.

drive when under the influence of alcohol or
drugs (including prescription or over the-
counter drugs which may cause drowsiness).
Always wear your seat belt as outlined in the
“Safety – Seats, seat belts and supplemental
restraint system” section of this manual, and
also instruct your passengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers.In a rollover crash, an
unbelted or improperly belted person is sig-
nificantly more likely to be injured or killed
than a person properly wearing a seat belt.
OFF-ROAD RECOVERY
While driving, the right side or left side wheels
may unintentionally leave the road surface. If
this occurs, maintain control of the vehicle by
following the procedure below. Please note
that this procedure is only a general guide.
The vehicle must be driven as appropriate
based on the conditions of the vehicle, road
and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel
with both hands and try to hold a straight
course.4. When appropriate, slowly release the ac-
celerator pedal to gradually slow the ve-
hicle.
5. If there is nothing in the way, steer the
vehicle to follow the road while vehicle
speed is reduced. Do not attempt to drive
the vehicle back onto the road surface
until vehicle speed is reduced.
6. When it is safe to do so, gradually turn the
steering wheel until both tires return to
the road surface. When all tires are on the
road surface, steer the vehicle to stay in
the appropriate driving lane.
If you decide that it is not safe to return
the vehicle to the road surface based on
vehicle, road or traffic conditions, gradu-
ally slow the vehicle to a stop in a safe
place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving on
under-inflated tires.
Rapid air pressure loss can affect the han-
dling and stability of the vehicle, especially at
highway speeds.Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspect the tires for wear and damage. For
additional information, refer to “Wheels and
tires” in the “Maintenance and do-it-yourself”
section of this manual. If a tire rapidly loses air
pressure or “blows-out” while driving, main-
tain control of the vehicle by following the
procedure below. Please note that this pro-
cedure is only a general guide. The vehicle
must be driven as appropriate based on the
conditions of the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
•The vehicle generally moves or pulls in
the direction of the flat tire.
•Do not rapidly apply the brakes.
•Do not rapidly release the accelerator
pedal.
•Do not rapidly turn the steering wheel.
1. Remain calm and do not overreact.
Starting and driving5-9

•Do not shift gears while driving on
downhill grades as this could cause loss
of control of the vehicle.
•Stay alert when driving to the top of a
hill. At the top there could be a drop-off
or other hazard that could cause an ac-
cident.
•If your engine stalls or you cannot make
it to the top of a steep hill, never at-
tempt to turn around. Your vehicle could
tip or roll over. Always back straight
down in R (Reverse) gear and apply
brakes to control your speed.
•Heavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed.
•Unsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
•Secure heavy loads in the cargo area as
far forward and as low as possible. Do
not equip the vehicle with tires larger
than specified in this manual. This could
cause your vehicle to roll over.
•Do not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move suddenly
and injure your hands. Instead drive with
your fingers and thumbs on the outside
of the rim.
•Before operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
•Always drive with the floor mats in place
as the floor may become hot.
•Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your INFINITI is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
•Do not drive beyond the performance
capability of the tires, even with AWD
engaged.
•For AWD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
drive or reverse position with the engine
running. Doing so may result in drive-
train damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
•Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing), or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious ve-
hicle damage or personal injury.
•When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
•Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause
loss of control.
•If at all possible, avoid sharp turning ma-
neuvers, particularly at high speeds.
Your INFINITI vehicle has a higher cen-
ter of gravity than a passenger car. The
vehicle is not designed for cornering at
the same speeds as passenger cars. Fail-
ure to operate this vehicle correctly
could result in loss of control and/or a
rollover accident.
Starting and driving5-11

•Always use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
•Be sure to check the brakes immediately
after driving in mud or water. .
•Avoid parking your vehicle on steep hills.
If you get out of the vehicle and it rolls
forward, backward or sideways, you
could be injured.
•Whenever you drive off-road through
sand, mud or water as deep as the wheel
hub, more frequent maintenance may be
required. For additional information, re-
fer to "Maintenance schedules".
ALL-WHEEL DRIVE (AWD)
DRIVING SAFETY PRECAUTIONS
(IF SO EQUIPPED)
WARNING
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
•For AWD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
D (Drive) or R (Reverse) position with
the engine running. Doing so may result
in drivetrain damage or unexpected ve-
hicle movement which could result in se-
rious vehicle damage or personal injury
•Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer, (such as the dynamometers
used by some states for emissions test-
ing), or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious ve-
hicle damage or personal injury.
•When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
5-12Starting and driving

You do not have to remove the start/stop
button from the ignition lock when you leave
the vehicle. You should, however, always
take the key with you when leaving the ve-
hicle. As long as the key is in the vehicle:
•The vehicle can be started using the push-
button ignition switch.
•The electrically powered equipment can be
operated.

BEFORE STARTING ENGINE STARTING ENGINE
5-16Starting and driving

CAUTION
Do not drive over obstacles such as curbs,
as you may damage the wheels or tires.
IPA may also display spaces not suitable for
parking, for example:
•Parking or stopping prohibition.
•In front of driveways or entrances and
exits.
•Unsuitable surfaces.
Parking tips:
•On narrow roads, drive as closely as pos-
sible past the parking space.
•Parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
•Parking spaces that are partly occupied by
trailer towing bars might not be identified
as such or be measured incorrectly.
•Snowfall or heavy rain may lead to a park-
ing space being measured inaccurately.
•Pay attention to the sonar function warn-
ing messages during the parking proce-
dure.
•You can intervene in the steering proce-
dure to correct it at any time. IPA will then
be canceled.
•When transporting a load which protrudes
from your vehicle, you should not use IPA.
•Never use IPA when snow chains are fit-
ted.
•Make sure that the tire pressures are al-
ways correct. This has a direct influence on
the parking characteristics of the vehicle.
Use IPA for parking spaces that are:
•Parallel or at right angles to the direction
of travel.
•On straight roads, not bends.
•On the same level as the road, e. g. not on
the sidewalk.
For vehicles with the towbar folded out, the
minimum length for parking spaces is slightly
longer.
If you have attached a trailer to your vehicle,
you may not use IPA. Once the electrical
connection is established between your ve-
hicle and the trailer, IPA is no longer available.
The sonar function is deactivated for the rear
area
DETECTING PARKING SPACES
The IPA system can only be used to park in
spaces that have vehicles directly on either
side of the parking space.
Objects located above the height range of
IPA will not be detected when the parking
space is measured. These are not taken into
account when the parking procedure is calcu-
lated, e. g. overhanging loads, tail sections or
loading ramps of goods vehicles.
WARNING
If there are objects above the detection
range, IPA may steer too early. This could
cause a collision. There is a risk of an acci-
dent.
If objects are located above the detection
range, stop and switch off the IPA.
For further information on the detection
range see "Range of the sensors" later in this
section.
Starting and driving5-71

•Keep your engine tuned up.
•Follow the recommended scheduled
maintenance.
•Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
•Keep all the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
•Use the recommended viscosity engine oil.
For additional information, see "Recom-
mended fluids/lubricants and capacities"
WARNING
•Do not drive beyond the performance
capability of the tires, even with 4WD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
•For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
drive or reverse position with the engine
running. Doing so may result in drive-
train damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
•Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) or
similar equipment even if the other two
wheels are raised off the ground. Make
sure that you inform the test facility
personnel that your vehicle is equipped
with 4WD before it is placed on a dyna-
mometer. Using the wrong test equip-
ment may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage or
personal injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.
INCREASING FUEL ECONOMY FOUR-WHEEL DRIVE (4WD) (IF
EQUIPPED)
5-86Starting and driving

CAUTION
Never tow the vehicle with one axle raised.
This may damage the differential. Damage
of this sort is not covered by the warranty.
All wheels must be fully raised (see "Four-
Wheel Drive (4WD) models")
4WD, together with VDC, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style, 4WD
can neither reduce the risk of an accident nor
override the laws of physics. 4WD cannot
take account of road, weather, and traffic
conditions. 4WD is only an aid. You are re-
sponsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
If a drive wheel spins due to insufficient grip
•When pulling away, only depress the ac-
celerator pedal as far as is necessary.
•Accelerate less when driving.
NOTE
In wintry driving conditions, the maximum
effectiveness of 4WD can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
WARNING
•Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
•Safe parking procedures require that
both the parking brake be applied and
the P (Park) position engaged. Failure to
do so could cause the vehicle to move
unexpectedly or roll away and result in
an accident.
•When parking the vehicle, make sure the
P (Park) position is engaged. The shift
lever cannot be moved out of the P
(Park) position without depressing the
brake pedal.
•Never leave the engine running while the
vehicle is unattended.
•Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or move the
vehicle. Unattended children could be-
come involved in serious accidents.
•To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others, or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or death
to people and pets.
CAUTION
Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its
drive train could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
•The electric parking brake must be applied.
•The transmission must be in position P
(Park) and the transmission position dis-
play must show P in the vehicle informa-
tion display.
•The key must be removed from the ignition
switch.
•On uphill or downhill gradients, the front
wheels must be turned towards the curb.

EXTENDED PARKING
If you leave the vehicle parked up for longer
than four weeks, the battery may be dam-
aged by exhaustive discharging.
If you leave the vehicle parked up for longer
than six weeks, it may suffer from lack of use.
Visit an INFINITI retailer and seek advice
NOTE
You can obtain information about trickle
chargers from an INFINITI retailer.The electric power steering system is de-
signed to reduce the driver effort required to
steer the vehicle.
WARNING
If during operation a fault is detected the
following message will be displayed in the
vehicle information display along with an
audible warning tone.
[Power Steering Malfunction See Opera-
tors Manual]
In conjunction with this warning, steering
assistance will no longer be provided by the
system.
The effort required to steer the vehicle will
increase. This will be most noticeable at
low speed and when performing a tight
turning maneuver.
Check whether you are able to provide the
extra effort required.
If you are able to steer safely: Carefully
drive on to an INFINITI retailer.
If
you are unable to steer safely: Do NOT
drive on. It is recommended you contact the
nearest INFINITI retailer for assistance.
CAUTION
•If wheels or tires other than INFINITI
recommended ones are used, the power
steering system may not operate prop-
erly and the [Power Steering Malfunc-
tion See Operators Manual] warning
may appear in the vehicle information
display.
•Do not modify the vehicle's suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
recommended for your vehicle or are ex-
tremely deteriorated, the power steer-
ing system may not operate properly
and the [Power Steering Malfunction
See Operators Manual] warning may
appear in the vehicle information dis-
play.
•Do not modify the vehicle's steering. If
steering parts are not INFINITI recom-
mended for your vehicle or are ex-
tremely deteriorated, the power steer-

brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes func-
tion correctly.
Driving uphill
When starting on a steep gradient, it is some-
times difficult to operate the brake. Use the
parking brake to hold the vehicle. When ready
to start, make sure that the shift lever is in an
appropriate forward or reverse driving posi-
tion, release the parking brake while depress-
ing the accelerator pedal. If your vehicle has
an electric parking brake, this will automati-
cally release when you depress the accelera-
tor pedal (DCT models).
Driving downhill
The engine braking action is effective for
controlling the vehicle while descending hills.
A low gear position in the manual shift mode,
low enough to obtain sufficient engine brak-
ing, should be selected.
Parking brake break-in
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weak-
ened or whenever the parking brake shoes
and/or drums/rotors are replaced, in order to
assure the best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot prevent
accidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking on
slippery surfaces. Remember that stopping
distances on slippery surfaces will be lon-
ger than on normal surfaces even with
ABS. Stopping distances may also be lon-
ger on rough, gravel or snow covered
roads, or if you are using tire chains. Al-
ways maintain a safe distance from the ve-
hicle in front of you. Ultimately, the driver
is responsible for safety.
Tire type and condition may also affect
braking effectiveness.
–When replacing tires, install the specified
size of tires on all four wheels.–When installing a replacement tire, make
sure that it is the proper size and type as
specified on the tire and loading informa-
tion label. (See "Wheels and Tires".)
–For detailed information, see "Wheels and
tires".
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during
hard braking or when braking on slippery sur-
faces. The system detects the rotation speed
at each wheel and varies the brake fluid pres-
sure to prevent each wheel from locking and
sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain
steering control and helps to minimize swerv-
ing and spinning on slippery surfaces.
Using 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.
