CAUTION
•Do not use leaded gasoline. (SeeRecom-
mended fluids/lubricants and capacitiesin
the9. Maintenance and Schedulessec-
tion.) Deposits from leaded gasoline seri-
ously reduce the ability of the three-way
catalyst to help reduce exhaust pollutants
and/or damage the three-way catalyst.
•Keep your engine tuned up. Malfunctions in
the ignition, fuel injection, or electrical sys-
tems may cause overrich fuel to flow into
the three-way catalyst, causing it to over-
heat. Do not keep driving if the engine mis-
fires, or if noticeable loss of performance or
other unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended you visit an
INFINITI retailer for this service.
•Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-way
catalyst.
•Do not race the engine while warming it up.
•Do not push or tow your vehicle to start the
engine.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
Each tire, including the spare (if present),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS malfunc-
tion indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from working properly. Always check
the TPMS telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
The vehicle’s wheels have sensors fitted that
monitor the tire pressures in all four tires The
tire pressure monitor warns you if the pressure
drops in one or more of the tires The tire
pressure monitor only functions if the corre-
sponding sensors are fitted to all wheels.
Information on tire pressures is shown in the
vehicle information display. After a few minutes
of driving, the current tire pressure of each tire
is shown in the [Serv.] menu of the vehicle
information display.

WARNING
•Radio waves could adversely affect electri-
cal medical equipment. Those who use a
pacemake should contact their electrical
medical equipment manufacturer for the
pssible influences before use.
•If the low tire pressure warning light illumi-
nates or a tire pressure-related warning is
displayed by the vehicle information dis-
play while driving, avoid sudden steering
maneuvers or abrupt braking, reduce ve-
hicle speed, pull off the road to a safe loca-
tion and stop the vehicle as soon as pos-
sible. Driving with under-inflated tires may
permanently damage the tires and increase
the likelihood of tire failure. Serious vehicle
damage could occur and may lead to an ac-cident and could result in serious personal
injury. Check the tire pressure for all four
tires. Adjust the tire pressure to the recom-
mended COLD tire pressure shown on the
tire and loading information label to turn
the low tire pressure warning light OFF. If
you have a flat tire, replace it with a replace-
ment tire as soon as possible.
•If a replacement wheel is fitted without an
INFINITI TPMS Sensor, 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. It is
recommended you contact an INFINITI re-
tailer as soon as possible for tire replace-
ment and/or system resetting.
•For models with run-flat tires, although you
can continue driving with a punctured run-flat
tire, remember that vehicle handling stability
is reduced, which could lead to an accident
and personal injury. Also, driving a long dis-
tance at high speeds may damage the tires.
–Do not drive at speeds above 50 MPH (80
km/h) and do not drive more than approxi-
mately 93 miles (150 km) with a punctured
run-flat tire. The actual distance the ve-
hicle 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 punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously dam-
aged and need to be replaced.
•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 repairing or re-
placing the tire (for models equipped with
the emergency tire puncture repair kit). It is
recommended you visit an INFINITI retailer
for this service.
•INFINITI recommends using only INFINITI
Genuine Emergency Tire Sealant provided
with your vehicle. Other tire sealants may
damage the valve stem seal which can
cause the tire to lose air pressure (for mod-
els equipped with the emergency tire punc-
ture repair kit).

5-6Starting and driving

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 metalized 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 pressure
suitable for the operating situation (see
Wheels and tiresin the8. Do-it-yourself
section). Note that the correct tire pressure for
the current operating situation must first be
taught-in to the tire pressure monitor (see
Restarting TPMSlater 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. Re-
start the tire pressure monitor after adjusting 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 significantly.
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 maneuvers.
TPMS has a yellow warning lamp in the combi-
nation meter for indicating a pressure loss or
malfunction. Depending on how the warning
lamp flashes or lights up, a tire pressure that is
too low or a malfunction in TPMS is indicated:
•If the warning lamp is lit continuously, the
tire pressure on one or more tires is signifi-
cantly too low. TPMS is not malfunctioning.
•If the warning lamp flashes for around a
minute and then remains lit constantly, the
TPMS is malfunctioning.
In addition to the warning lamp, a message
appears in the vehicle information display. Ob-
serve the information on display messages (see
Safety systemsin the2. Instruments and
controlssection
It may take up to ten minutes for a malfunction
of the tire pressure monitor to be indicated. A
malfunction will be indicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
fault has been rectified, the tire pressure warn-
ing lamp goes out after you have driven for a
few minutes.The tire pressure values indicated by the ve-
hicle information display may differ from those
measured at a filling station using a pressure
gauge. The tire pressures shown by the vehicle
information display are those measured at sea
level. At high altitudes, the tire pressure values
indicated by a pressure gauge are higher than
those shown by the vehicle information display.
In this case, do not reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interference from radio transmit-
ting equipment (e.g. radio head phones, two-
way radios) that may be being operated in or
near the vehicle.Checking the tire pressure
electronically
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 current tire pressure for each wheel will
be displayed in the vehicle information dis-
play.
Starting and driving5-7

If the vehicle was parked for longer than 20
minutes, the [Tire pressures will be displayed
after driving a few minutes] message is shown.
After a teach-in period, the tire pressure moni-
tor automatically detects new wheels or new
sensors. If a clear allocation of tire pressure to
individual wheels is not possible, the Tire pres-
sure monitor active message is shown instead
of the tire pressure display. The tire pressures
are already being monitored.
If a replacement wheel is fitted, for a few
minutes the system may continue to show the
tire pressure of the wheel that has been re-
moved. If this occurs, note that the value dis-
played for the position where the replacement
wheel is fitted is not the same as the current tire
pressure of the replacement wheel.
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 lamp comes on.
•If the [Please Correct Tire Pressure] (yellow)
message appears in the vehicle information
display, the tire pressure in at least one tire
is too low and must be corrected at the next
opportunity. If the system detects that new
sensors have been fitted (IDs do not match
those stored, and the pressure is not fea-
sible, or is less than 14% under the norm
then the [Please Correct Tire Pressure] mes-
sage will be displayed in white.
•If the [Check Tires] (red) message appears in
the vehicle information display, the tire pres-
sure in one or more tires has dropped sig-
nificantly and the tires must be checked.
•If the [Warning Tire Malfunction] (red) message
appears in the vehicle information 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 dis-
play, one or more sensors are missing or
cannot be detected. This could be the result
of fitting a replacement wheel/tire.Observe the instructions and safety notes in the
display messages in the vehicle information
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 correct
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 lamps go out. The monitor uses the
currently set tire pressures as the reference
values for monitoring. In most cases, the tire
pressure monitor will automatically detect the
new reference values after you have changed
the tire pressure. However, you can also define
reference values manually as described here.
The tire pressure monitor then monitors the
new tire pressure values.

IPA is an electronic parking aid with ultrasound.
It detects vehicles and open spaces on both
sides of the vehicle. A parking symbol indicates
a suitable parking space. Active steering inter-
vention can assist you during parking and when
exiting a parking space. The driver controls the
accelerator, brake and gear shift. You may also
use the parking sensor system (seeParking
sensor system (if equipped)later in this sec-
tion).
IMPORTANT SAFETY NOTES
WARNING
•IPA is only an aid. It is not a substitute for
your attention to the immediate surround-
ings. The responsibility for safe maneuver-
ing and parking remains with you.
•Make sure that no persons, animals or ob-
jects are in the maneuvering range
•When the parking sensor system is deacti-
vated, IPA is also unavailable.
•While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
•Pay attention to other road users. Stop the
vehicle if necessary or cancel the IPA park-
ing procedure
•This system is not designed to prevent con-
tact with small or moving objects.
•If your vehicle sustains damage to the bumper
fascia, leaving it misaligned or bent, the sens-
ing zone may be altered causing inaccurate
measurement of obstacles or false alarms.
•This system is not designed to prevent con-
tact with small or moving objects.
•If your vehicle sustains damage to the bumper
fascia, leaving it misaligned or bent, the sens-
ing zone may be altered causing inaccurate
measurement of obstacles or false alarms.
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 incor-
rectly.
•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 parking
space being measured inaccurately.
•Pay attention to the parking sensor system
warning messages during the parking proce-
dure.
•You can intervene in the steering procedure
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 fitted.
•Make sure that the tire pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle.

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 information label. (See
Wheels and Tiresin the9. Maintenance and
Schedulessection.)
–For detailed information, seeWheels and
tiresin the8. Do-it-yourselfsection.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving 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.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle at a low speed in
forward or reverse. When the self-test occurs,
you may hear a “clunk” noise and/or feel a
pulsation in the brake pedal. This is normal and
does not indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked. It is recommended you visit an
INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, the VDC system helps to perform the
following functions.
•Controls brake pressure to reduce wheel slip
on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
•Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function).
•Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow
the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to
certain road or driving conditions).
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.When the VDC system operates, the VDC warn-
ing light in the instrument panel flashes so note
the following:
•The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
•You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
•Adjust your speed and driving to the road
conditions.
SeeVehicle Dynamic Control (VDC) warning
lightin the2. Instruments and controlssec-
tion.
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
WARNING
•The VDC system is designed to help the
driver maintain stability but does not pre-
vent accidents due to abrupt steering opera-
tion at high speeds or by careless or danger-
ous driving techniques. Reduce vehicle
speed and be especially careful when driv-
ing and cornering on slippery surfaces and
always drive carefully.
•Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the VDC system may not operate
properly. This could adversely affect vehicle
handling performance, and the VDC warning
light
may illuminate.
•If brake related parts such as brake pads,
rotors and calipers are not INFINITI recom-
mended or are extremely deteriorated, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
•If engine control related parts are not
INFINITI recommended or are extremely de-
teriorated, the VDC warning light
may
illuminate.

The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the low
tire pressure warning light is lit, and a tire
pressure-related warning (if equipped) appears
in the vehicle information display, one or more
of your tires is significantly under-inflated. If
the vehicle is being driven with low tire pres-
sure, the TPMS will activate and warn you of it
by the low tire pressure warning light (in the
