•When using a wheel without the TPMS
such as the spare tire, the TPMS will not
function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will remain on
after 1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit an INFINITI retailer for these
services.
• 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.
Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or
blinks while the engine is running, it may indi-
cate a potential emission control
malfunction.
The MIL 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
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 comes on steady 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. For ad-
ditional information, see “Readiness for
Inspection/Maintenance (I/M) test”
(P. 10-24).
Operation
The MIL will come on in one of two ways:
• MIL on steady — An emission control sys- tem malfunction has been detected. Check
the fuel-filler cap. 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
checked. It is recommended that you visit
an INFINITI retailer for this service. You do
not need to have your vehicle towed to the
retailer.
• MIL blinking — An engine misfire has been detected which may damage the emission
control system. To reduce or avoid emis-
sion control system damage:– Do not drive at speeds above 45 mph (72 km/h).
– Avoid hard acceleration or deceleration.
– Avoid steep uphill grades.
– If possible, reduce the amount of cargo being hauled or towed.
The MIL may stop blinking and come on
steady. Have the vehicle checked. It is recom-
mended that you visit an INFINITI retailer for
this service. You do not need to have your
vehicle towed to the retailer.

CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.

When the ignition switch is in the ON posi-
tion, the power steering warning light illumi-
nates. After starting the engine, the power steering warning light stays on for a few
seconds and turns off. This indicates that
Direct Adaptive Steering is operational. Drive
the vehicle after the power steering warning
light turns off.
If the power steering warning light illumi-
nates while driving, pull off the road to a safe
location and stop the vehicle. If the power
steering warning light turns off, you can drive

Models with electric power steering:
When the ignition switch is in the ON posi-
tion, the power steering warning light illumi-
nates. After starting the engine, the power
steering warning light turns off. This indicates
the electric power steering is operational.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the electric power steering is not func-
tioning properly and may need servicing. It is
recommended that you have the electric
power steering checked by an INFINITI
retailer.

FUEL-FILLER CAP
WARNING
• Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled. Al-
ways stop the engine and do not smoke
or allow open flames or sparks near the
vehicle when refueling.
• Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off au-
tomatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.

FUEL-FILLER DOOR
Pre-driving checks and adjustments3-29

•Use only an original equipment type fuel-
filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap can
result in a serious malfunction and pos-
sible injury. It could also cause the
Malfunction Indicator Light (MIL) to
come on.
• Never pour fuel into the throttle body to
attempt to start your vehicle.
• Do not fill a portable fuel container in the
vehicle or trailer. Static electricity can
cause an explosion of flammable liquid,
vapor or gas in any vehicle or trailer. To
reduce the risk of serious injury or death
when filling portable fuel containers:
– Always place the container on the
ground when filling.
– Do not use electronic devices when
filling.
– Keep the pump nozzle in contact with
the container while you are filling it.
– Use only approved portable fuel con-
tainers for flammable liquid.
CAUTION
• Do not use a fuel containing more than
15% ethanol in your vehicle. For addi-
tional information, see “Fuel recommen-
dation” (P. 10-3).
• The Loose Fuel Cap warning message
will be displayed if the fuel-filler cap is
not properly tightened. It may take a few
driving trips for the message to be dis-
played. Failure to tighten the fuel-filler
cap properly after the Loose Fuel Cap
warning is displayed may cause the Mal-
function Indicator Light (MIL) to
illuminate.
• Tighten until the fuel filler cap clicks.
Failure to tighten the fuel-filler cap
properly may cause the
Malfunc-
tion Indicator Light (MIL) to illuminate.
If the
light illuminates because 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 rec-
ommended that you visit an INFINITI re-
tailer for this service. •
For additional information, see “Mal-
function Indicator Light (MIL)”
(P. 2-15).
• If fuel is spilled on the vehicle body, flush
it away with water to avoid paint
damage.
