injury to yourself or others, have your
vehicle checked. It is recommended you
visit an INFINITI retailer for this service.
WARNING/INDICATOR LIGHTS
(yellow)
See “Vehicle information display” (P.2-18).
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 indicates the ABS is opera-
tional.
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. It is recommended
you visit an INFINITI retailer for this service.
If an ABS malfunction occurs, the anti-lock
function is turned off. The brake system then
operates normally, but without anti-lock
assistance. (See “Brake system” (P.5-125).)
Forward Emergency Braking
(FEB) system warning light
This light comes on when the ignition switch
is placed in the ON position. It turns off after
the engine is started.
This light illuminates when the FEB system is
set to OFF on the lower display.
If the light illuminates when the FEB system
is ON, it may indicate that the system is
unavailable. See “Forward Emergency Brak-
ing (FEB)” (P.5-102) for more details.
Front passenger air bag status
light
The front passenger air bag status light
() located on the instrument panel will be
lit and the passenger front air bag will be
OFF depending on how the front passenger
seat is being used.
For front passenger air bag status light
operation, see “INFINITI Advanced Air Bag
System (front seats)” (P.1-48).
Low fuel warning light
This light illuminates when the fuel in the
tank is getting low. Refuel as soon as it is
convenient, preferably before the fuel gauge
reaches the 0 (empty) position. There will be a small reserve of fuel remain-
ing in the tank when the fuel gauge reaches
the 0 position.
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
tire (if so equipped).
The low tire pressure warning light warns of
low tire pressure and flat tire (if so equipped)
or indicates that the TPMS is not functioning
properly.
After the ignition switch is placed in the ON
position, 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.
The “Tire Pressure Low - Add Air” warning
also appears in the vehicle information dis-
play.
When the low tire pressure warning light
illuminates, you should stop and adjust the
tire pressure to the recommended COLD tire
pressure shown on the Tire and Loading
Information label. 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
Instruments and controls2-13

driving a long distance at high speeds
may damage the tires.— Do not drive at speeds above 50 MPH (80 km/h) and do not drive
more than approximately 93 miles
(150 km) with a punctured run-
flat tire. The actual distance the
vehicle 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 possi-
ble. The tire may be seriously
damaged and need to be replaced.
. Since the spare tire is not equipped
with the TPMS, 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 remain on after the 1 minute.
Have your tires replaced and/or
TPMS system reset as soon as pos-
sible. It is recommended you visit an
INFINITI retailer for these services.
. Replacing tires with those not origin-
ally 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.
Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is running,
it may indicate a potential emission control
malfunction.
The malfunction indicator light may also
come on steady if the fuel-filler cap is loose
or missing, or if the vehicle runs out of fuel.
Check to make sure the fuel-filler cap is
installed and closed tightly, and that the
vehicle has at least 3 US gallons (11.4 liters)
of fuel in the fuel tank.
After a few driving trips, the
light should turn off if no other potential emission
control system malfunction exists.
If this indicator light remains on for 20
seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance test.
(See “Readiness for Inspection/Mainte-
nance (I/M) test (US only)” (P.10-23).)
Operation:
The malfunction indicator light will come on
in one of two ways:
.
Malfunction indicator light on steady —
An emission control system malfunction
has been detected. Check the fuel-filler
cap if the Loose Fuel Cap warning
appears in the vehicle information dis-
play. If the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off after a few driving
trips. If thelight does not turn off
after a few driving trips, have the vehicle
inspected. It is recommended you visit an
INFINITI retailer for this service. You do
not need to have your vehicle towed to
the retailer.
. Malfunction indicator light blinking — An
engine misfire has been detected which
may damage the emission control sys-
tem.

REARVIEW MONITOR SYSTEM
LIMITATIONS
WARNING
Listed below are the system limitations
for RearView Monitor. Failure to oper-
ate the vehicle in accordance with these
system limitations could result in serious
injury or death.
.The system cannot completely elim-
inate blind spots and may not show
every object.
. Underneath the bumper and the
corner areas of the bumper cannot
be viewed on the RearView Monitor
because of its monitoring range lim-
itation. The system will not show
small objects below the bumper, and
may not show objects close to the
bumper or on the ground.
. Objects viewed in the RearView
Monitor differ from actual distance
because a wide-angle lens is used.
. Objects in the RearView Monitor will
appear visually opposite compared to
when viewed in the rearview and
outside mirrors. .
Use the displayed lines as a reference.
The lines are highly affected by the
number of occupants, fuel level, ve-
hicle position, road conditions and
road grade.
. Make sure that the trunk lid is
securely closed when backing up.
. Do not put anything on the rearview
camera. The rearview camera is in-
stalled above the license plate.
. When washing the vehicle with high-
pressure water, be sure not to spray
it around the camera. Otherwise,
water may enter the camera unit
causing water condensation on the
lens, a malfunction, fire or an electric
shock.
. Do not strike the camera. It is a
precision instrument. Otherwise, it
may malfunction or cause damage
resulting in a fire or an electric shock.
The following are operating limitations and
do not represent a system malfunction:
. When the temperature is extremely high
or low, the screen may not clearly display
objects.
. When strong light is directly coming on
the camera, objects may not be displayed
clearly. .
Vertical lines may be seen in objects on
the screen. This is due to strong reflected
light from the bumper.
. The screen may flicker under fluorescent
light.
. The colors of objects on the RearView
Monitor may differ somewhat from the
actual color of objects.
. Objects on the monitor may not be clear
in a dark environment.
. There may be a delay when switching to
the RearView Monitor.
. If dirt, rain or snow accumulates on the
camera, the RearView Monitor may not
display object clearly. Clean the camera.
. Do not use wax on the camera lens. Wipe
off any wax with a clean cloth dampened
with a diluted mild cleaning agent, then
wipe with a dry cloth.
Monitor, climate, audio, phone and voice recognition systems4-9

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials away
from the exhaust system compo-
nents.
. 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.
CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst’s ability to
help reduce exhaust pollutants.
. Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems 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 in-
spected 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 provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended 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 Mon-
itoring System (TPMS) that illuminates a low
tire pressure 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 pressure. 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.
For models with run-flat tires, if the vehicle
is being driven with one or more flat tires,
the low tire pressure warning light will
illuminate continuously and a chime will
sound for 10 seconds. The flat tire warning
will also appear in the vehicle information
display. The chime will only sound at the first
indication of a flat tire, and the warning light
will illuminate continuously. When the flat
tire warning is activated, it is recommended
you have the system reset and the tire
checked and replaced if necessary by an
INFINITI retailer. Even if the tire is inflated
to the specified COLD tire pressure, the
warning light will continue to illuminate until
the system is reset by an INFINITI retailer.
Your vehicle can be driven for a limited time
on a flat tire. See “Run-flat tires” (P.8-32).
Starting and driving5-5

4. Drive at economical speeds and dis-tances.
.Observing the speed limit and notexceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.
.Maintaining a safe following distance
behind other vehicles reduces unne-
cessary braking.
.Safely monitoring traffic to anticipatechanges in speed permits reduced
braking and smooth acceleration
changes.
.Select a gear range suitable to roadconditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady speed.
.Cruise control is particularly effectivein providing fuel savings when driving
on flat terrains.
6. Plan for the shortest route.
.Utilize a map or navigation system to determine the best route to save time.
7. Avoid idling.
.Shutting off your engine when safe for stops exceeding 30-60 seconds
saves fuel and reduces emissions. 8. Buy an automated pass for toll roads.
.Automated passes permit drivers to
use special lanes to maintain cruising
speed through the toll and avoid
stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to fuel economy.
.Vehicles typically need no more than30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal oper-ating temperature more quickly while
driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade whenever possi-
ble.
.When entering a hot vehicle, openingthe windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system. .
Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-6).)

8-2Do-it-yourself
When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself 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 moving. Move the shift
lever to P (Park).
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. Never connect or disconnect the
battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.
. If you must work with the engine
running, 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 remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
. Always wear eye protection when-
ever you work 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 only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
. Because the fuel lines are under high
pressure even when the engine is off,
it is recommended you visit an
INFINITI retailer for service of the fuel filter or fuel lines.
CAUTION
.
Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
. Avoid direct contact with used en-
gine oil and coolant. Improperly dis-
posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items which
are relatively easy for an owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-24).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and could
affect your warranty coverage. If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.
