FUEL-FILLER CAP
WARNING
●Gasoline is extremely flammable and highly
explosive under certain conditions. You
could be burned or seriously injured if it is
misused or mishandled. Always stop 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 automati-
cally. Continued refueling may cause fuel
overflow, resulting in fuel spray and possi-
bly a fire.
● 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 sys-
tem. An incorrect cap can result in a serious
malfunction and possible injury. It could
also cause the malfunction indicator light to
come on.
● Never pour fuel into the throttle body to at-
tempt 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 contain- ers for flammable liquid.
CAUTION
●If fuel is spilled on the vehicle body, flush it
away with water to avoid paint damage.
● Insert the cap straight into the fuel-filler
tube, then tighten until the fuel-filler cap
clicks. Failure to tighten the fuel-filler cap
properly may cause the
malfunction
indicator light (MIL) to illuminate. If the
light illuminates because the fuel-
filler cap is loose or missing, tighten or in-
stall the cap and continue to drive the ve-
hicle. 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 by an INFINITI retailer.
● The LOOSE FUEL CAP warning (if so
equipped) will appear if the fuel-filler cap is
not properly tightened. Failure to tighten the
fuel-filler cap properly after the LOOSE FUEL
CAP warning (if so equipped) appears may
cause the Malfunction Indicator Light (MIL)
to illuminate.
3-18Pre-driving checks and adjustments

Confirming memory storage
●Push the ignition switch to the ON position
and push the SET switch. If the main memory
has not been stored, the indicator light will
come on for approximately 0.5 second.
When the memory has stored in position, the
indicator light will stay on for approximately
5 seconds.
● If the battery cable is disconnected, or if the
fuse opens, the memory will be canceled. In
this case, reset the desired position using
the previous procedure.
● If optional Intelligent Keys are added to your
vehicle, the memory storage procedure to
switch 1 or 2 and linking Intelligent Key
procedure to a stored memory position
should be performed again for each Intelli-
gent Key. For additional Intelligent Key infor-
mation, see “KEYS” earlier in this section.
Selecting the memorized position
1. Move the selector lever to the P (Park) position.
2. Use one of the following methods to move the driver’s seat, the outside mirrors and
the steering wheel.
●Push the ignition switch to the ON posi-
tion and push the memory switch (1 or 2)
fully for at least 1 second. ●
Within 45 seconds of opening the driver’s
door, push the memory switch (1 or 2)
fully for at least 1 second.
The driver’s seat, steering column and
outside mirrors will move to the memo-
rized position or to the exit position when
the entry/exit function is set to active with
the indicator light flashing, and then the
light will stay on for approximately 5
seconds.
SYSTEM OPERATION
The automatic drive positioner system will not
work or will stop operating under the following
conditions:
● When the vehicle speed is above 4 MPH
(7 km/h).
● When the adjusting switch for the driver’s
seat and steering column is turned on while
the automatic drive positioner is operating.
● When the memory switch 1 or 2 is not
pushed for at least 1 second.
● When the seat, steering column and outside
mirrors have already been moved to the
memorized position.
● When no position is stored in the memory
switch. ●
When the engine is started while moving the
automatic drive positioner.
● When the AT selector lever is moved from the
P (Park) position to any other position. (How-
ever, it will not be canceled if the switch is
pushed while the seat and steering column
are returning to the previous positions
(entry/exit function).)
● When the driver’s door remains open for
more than 45 seconds and the ignition
switch is not in the ON position.
● The seat synchronization function is auto-
matically disabled if the outside mirrors or
steering wheel reaches its maximum adjust-
ment.
● The seat synchronization function will not
operate if the seat is adjusted over one of
the following maximum thresholds:
– Seat sliding: 3.0 in (76 mm)
– Seatback reclining: 9.1 degrees
– Seat lifter (rear side): 0.8 in (20 mm)
Pre-driving checks and adjustments3-27

●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

LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
●This system is only a warning device to in-
form the driver of a potential unintended
lane departure. It will not steer the vehicle or
prevent loss of control. It is the driver’s re-
sponsibility to stay alert, drive safely, keep
the vehicle in the traveling lane, and be in
control of the vehicle at all times.
● The system will not operate at speeds below
approximately 45 MPH (70 km/h) or if it can-
not detect lane markers.
● If the LDW system malfunctions, it will can-
cel automatically, and the lane departure
warning light (orange) will illuminate.
● If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the lane departure
warning light (orange) continues to illumi-
nate, have the system checked by an INFINITI
retailer. ●
Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
The system may not function properly under the
following conditions:
● On roads where there are multiple parallel
lane markers; lane markers that are faded or
not painted clearly; yellow painted lane
markers; non-standard lane markers; or lane
markers covered with water, dirt, snow, etc.
● On roads where the discontinued lane mark-
ers are still detectable.
● On roads where there are sharp curves.
● On roads where there are sharply contrast-
ing objects, such as shadows, snow, water,
wheel ruts, seams or lines remaining after
road repairs. (The LDW system could detect
these items as lane markers.)
● On roads where the traveling lane merges or
separates.
● When the vehicle’s traveling direction does
not align with the lane marker.
● When traveling close to the vehicle in front
of you, which obstructs the lane camera unit
detection range. ●
When rain, snow or dirt adheres to the
windshield in front of the lane camera unit.
● When the headlights are not bright due to
dirt on the lens or if the aiming is not
adjusted properly.
● When strong light enters the lane camera
unit. (For example, the light directly shines
on the front of the vehicle at sunrise or
sunset.)
● When a sudden change in brightness occurs.
(For example, when the vehicle enters or
exits a tunnel or under a bridge.)
