Pre-driving checks and adjustments3-31

∙ 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 emission
control system. An incorrect cap can re-
sult in a serious malfunction and possible
injury. It could also cause the
Mal-
function 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 than15% ethanol in your vehicle. For addi-
tional information, refer to “Fuel recom-
mendation” in the “Technical and con-
sumer information” section of this
manual.
∙ 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.
∙ Failure to tighten the fuel-filler cap prop- erly may cause the
Malfunction In-
dicator 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 the
light 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, refer to

surface. The apparent distance viewed
on the monitor may be different than the
actual distance between the vehicle and
displayed objects.
∙ Use the displayed lines and the bird’s-eye view as a reference. The lines and the
bird’s-eye view are greatly affected by
the number of occupants, cargo, fuel
level, vehicle position, road condition and
road grade.
∙ If the tires are replaced with different sized tires, the predicted course lines and
the bird’s-eye view may be displayed

CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
∙ Keep your engine tuned up. Malfunctions in the ignition, fuel injection, or electrical
systems can cause over rich fuel flow into
the three-way catalyst, causing it to
overheat. Do not keep driving if the en-
gine misfires, or if noticeable loss of per-
formance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly. It is recommended
that 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 Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all 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. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’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 approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels al-
low the TPMS to continue to function prop-
erly.
