without starting the engine. The following lights
will come on (if so equipped):
,or,,,,,
The following lights come on briefly and then go
off (if so equipped):
,or,,,,
,,,,
If any light does not come on, it may indicate a
burned-out bulb or an open circuit in the elec-
trical system. Have the system checked by an
INFINITI retailer.
Some indicators and warnings are also dis-
played on the dot matrix crystal display be-
tween the speedometer and tachometer. (See
“DOT MATRIX LIQUID CRYSTAL DISPLAY” later in
this section.)
WARNING LIGHTS
All-Wheel Drive (AWD)
warning light (AWD models)
Thewarning light comes on when the
ignition switch is pushed to ON. It turns off
soon after the engine is started.
If the AWD system malfunctions, or the diam-
eter of the front and the rear wheels are differ-
ent, the warning light will either remain illumi-
nated or blink. (See “ALL-WHEEL DRIVE (AWD)”
in the “5. Starting and driving” section.)
CAUTION
● If the warning light comes on while driving
there may be a malfunction in the AWD sys-
tem. Reduce the vehicle speed and have your
vehicle checked by an INFINITI retailer as
soon as possible.
● If the AWD warning light blinks on when you
are driving:
– blinks rapidly (about twice a second): Pull off the road in a safe area, and idle the
engine. The driving mode will change to
2WD to prevent the AWD system from
malfunctioning. If the warning light turns
off, you can drive again. – blinks slowly (about once every 2 sec-
onds):
Pull off the road in a safe area, and idle the
engine. Check that all tire sizes are the
same, tire pressure is correct and tires are
not worn.
● If the warning light is still on after the above
operations, have your vehicle checked by an
INFINITI retailer as soon as possible.
orAnti-lock Braking
System (ABS)
warning light
When the ignition switch is in the ON position,
the Anti-lock Braking System (ABS) warning
light illuminates and then turns off. This indi-
cates the ABS is operational.
If the ABS warning light illuminates while the
engine is running, or while driving, it may
indicate the ABS is not functioning properly.
Have the system checked by an INFINITI retailer.
If an ABS malfunction occurs, the anti-lock
function is turned off. The brake system then
operates normally, but without anti-lock assis-
tance. (See “BRAKE SYSTEM” in the “5. Starting
and driving” section.)
2-12Instruments and controls

If the light comes on in orange and remains on,
it may indicate that the LDW and LDP systems
are not functioning properly. Have the systems
checked by an INFINITI retailer.
See “LANE DEPARTURE WARNING (LDW)
SYSTEM/LANE DEPARTURE PREVENTION (LDP)
SYSTEM” in the “5. Starting and driving” sec-
tion.
Low tire pressure warning
light
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors the
tire pressure of all tires except the spare.
The low tire pressure warning light warns of low
tire pressure or indicates that the TPMS is not
functioning properly.
After the ignition switch is pushed ON, this light
illuminates for about 1 second and turns off.
Low tire pressure warning :
If the vehicle is being driven with low tire
pressure, the warning light will illuminate. A
CHECK TIRE PRESSURE warning also appears on
the dot matrix liquid crystal display.
When the low tire pressure warning light illumi-
nates, you should stop and adjust the tire
pressure to the recommended COLD tire pres-sure shown on the Tire and Loading Information
label. The low tire pressure warning light does
not automatically turn off when the tire pres-
sure is adjusted. After the tire is inflated to the
recommended 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 pressure
gauge to check the tire pressure.
The CHECK TIRE PRESSURE warning is active as
long as the low tire pressure warning light
remains illuminated.
For additional information, see “TIRE PRESSURE
MONITORING SYSTEM (TPMS)” in the “5. Start-
ing and driving” section and “TIRE PRESSURE
MONITORING SYSTEM (TPMS)” in the “6. 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
pushed ON. The light will remain on after the 1
minute. Have the system checked by an INFINITI
retailer. The CHECK TIRE PRESSURE warning
does not appear if the low tire pressure warning
light illuminates to indicate a TPMS malfunc-
tion.
For additional information, see “DOT MATRIX
LIQUID CRYSTAL DISPLAY” later in this section
and “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “5. Starting and driving” section.
WARNING
●
If the light does not illuminate with the igni-
tion switch pushed ON, have the vehicle
checked by an INFINITI retailer as soon as
possible.
● If the light illuminates while driving, avoid
sudden steering maneuvers or abrupt brak-
ing, 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. Serious
vehicle damage could occur and may lead to
an accident and could result in serious per-
sonal injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the rec-
ommended COLD tire pressure shown on the
Tire and Loading Information label to turn
the low tire pressure warning light OFF. If the
light still illuminates while driving after ad-
justing the tire pressure, a tire may be flat. If
you have a flat tire, replace it with a spare
tire as soon as possible.
Instruments and controls2-15

●When a spare tire is mounted or a wheel is
replaced, the TPMS will not function and the
low tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment 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 four wheels correctly.
Low washer fluid warning
light
This light comes on when the washer tank fluid
is at a low level. Add washer fluid as necessary. (See “WINDOW WASHER FLUID” in the “8. Main-
tenance and do-it-yourself” section.)

Preview Function warning
light (orange; if so equipped)
The light comes on if there is a malfunction in
the Preview Braking system.
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine, resume driving and set the ICC system
again. If it is not possible to set the system or the
indicator stays on, it may indicate that the sys-
tem is malfunctioning. Although the vehicle is
still driveable under normal conditions, have the
vehicle checked at an INFINITI retailer.
Seat belt warning light and
chime
The light and chime remind you to fasten seat
belts. The light illuminates whenever the igni-
tion switch is pushed to the ON position, and
will remain illuminated until the driver’s seat
belt is fastened. At the same time, the chime
will sound for about 6 seconds unless the
driver’s seat belt is securely fastened.
The seat belt warning light for the front passen-
ger will illuminate if the seat belt is not fastened
when the front passenger’s seat is occupied.
For 5 seconds after the ignition switch is in the
ON position, the system does not activate the
warning light for the front passenger.

●Keep your engine tuned up. Malfunctions in
the ignition, fuel injection, or electrical sys-
tems can cause overrich fuel flow into the
three-way catalyst, causing it to overheat.
Do not keep driving if the engine misfires, or
if noticeable loss of performance or other
unusual operating conditions are detected.
Have the vehicle inspected promptly by an
INFINITI retailer.
● 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 provided),
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 system is not operating properly. The TPMS
malfunction 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 continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not beable to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
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.
Additional information
●
The TPMS does not monitor the tire pressure
of the spare tire.
● The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h).
Also, this system may not detect a sudden
drop in tire pressure (for example a flat tire
while driving).
● The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended 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 pressure
gauge to check the tire pressure.
● The CHECK TIRE PRESSURE warning appears
in the vehicle information display when the
low tire pressure warning light is illuminated
Starting and driving5-3

and low tire pressure is detected. The CHECK
TIRE PRESSURE warning turns off when the
low tire pressure warning light turns off.
The CHECK TIRE PRESSURE warning does not
appear if the low tire pressure warning light
illuminates to indicate a TPMS malfunction.
● Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. This may cause
the low tire pressure warning light to illumi-
nate. If the warning light illuminates in low
ambient temperature, check the tire pres-
sure for all four tires.
For additional information, see “Low tire pres-
sure warning light” in the “2. Instruments and
controls” section and “TIRE PRESSURE MONI-
TORING SYSTEM (TPMS)” in the “6. In case of
emergency” section.WARNING
● If the low tire pressure warning light illumi-
nates 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 increase the likelihood
of tire failure. Serious vehicle damage could
occur and may lead to an accident and could
result 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 In-
formation label to turn the low tire pressure
warning light OFF. If the light still illumi-
nates while driving after adjusting the tire
pressure, a tire may be flat. If you have a flat
tire, replace it with a spare tire as soon as
possible. (See “FLAT TIRE” in the “6. In case
of emergency” section for changing a flat
tire.)
● When a spare tire is mounted or a wheel is
replaced, the TPMS will not function and the
low tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting. ●
Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
● Do not inject any tire liquid or aerosol tire
sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
CAUTION
● The TPMS may not function properly when
the wheels are equipped with tire 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.
Some devices and transmitters may temporarily
interfere with the operation of the TPMS and
cause the low tire pressure warning light to
illuminate. Some examples are:
● Facilities or electric devices using similar
radio frequencies are near the vehicle.
● If a transmitter set to similar frequencies is
being used in or near the vehicle.
