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. It may take a few driving trips for
the message to be displayed. Failure to
tighten the fuel-filler cap properly after the
LOOSE FUEL CAP warning (if so equipped) ap-
pears may cause the
Malfunction Indi-
cator Light (MIL) to illuminate.
The fuel-filler cap is a ratcheting type. Turn the
cap counterclockwise to remove. To tighten,
turn the cap clockwise until ratcheting clicks
are heard.

Linking Intelligent Key to a stored
memory position
The Intelligent Key can be linked to a stored
memory position with the following procedure.
1. Follow the steps for storing a memoryposition.
2. While the indicator light for the memory switch being set is illuminated for 5 sec-
onds, push the
button on the Intel-
ligent Key. If the indicator light blinks, the
Intelligent Key is linked to that memory
setting.
Push the ignition switch to the OFF position,
and then push thebutton on the Intelli-
gent Key. The driver’s seat, steering wheel and
outside mirrors will move to the memorized
position.
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.
3-32Pre-driving checks and adjustments

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. 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 all 4 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 be
able 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.
Starting and driving5-3

●Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Install tire chains on the rear wheels when
driving on slippery roads and drive carefully.
● Be sure to check the brakes immediately af-
ter driving in mud or water. See “BRAKE SYS-
TEM” later in this section for wet brakes.
● Avoid parking your vehicle on steep hills. If
you get out of the vehicle and it rolls forward,
backward or sideways, you could be injured.
● Whenever you drive off-road through sand,
mud or water as deep as the wheel hub, more
frequent maintenance may be required. See
the maintenance information in the “INFINITI
Service and Maintenance Guide”.
● Spinning the rear wheels on slippery sur-
faces may cause the 4WD warning light to
flash. The 4WD system may also automati-
cally switch from the 4WD mode to the 2WD
mode. This could reduce traction. Be espe-
cially careful when towing a trailer (4WD
models).WARNING
Do not operate the push-button ignition switch
while driving the vehicle except in an emer-
gency. (The engine will stop when the ignition
switch is pushed 3 consecutive times or the
ignition switch is pushed and held for more
than 2 seconds.) If the engine stops while the
vehicle is being driven, this could lead to a
crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the selector lever to the
P (Park) position.

●Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake fluid and window washer fluid as
frequently as possible, or at least whenever
you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Lock all doors.
● Position seat and adjust head
restraints/headrests.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is pushed to the ON
position. (See “WARNING/INDICATOR LIGHTS
AND AUDIBLE REMINDERS” in the “2. Instru-
ments and controls” section.)1. Apply the parking brake.
2. Move the selector lever to the P (Park) or
N (Neutral) position. (P is recommended.)
The starter is designed not to operate unless
the selector lever is in either of the above
positions.
3. Push the ignition switch to the ON posi-tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push and
release the ignition switch while depressing
the brake pedal with the ignition switch in
any position.
● If the engine is very hard to start in
extremely cold weather or when restart-
ing, depress the accelerator pedal a little
(approximately 1/3 to the floor) and while
holding, crank the engine. Release the
accelerator pedal when the engine starts.
● If the engine is very hard to start because
it is flooded, depress the accelerator
pedal all the way to the floor and hold it.
Push the ignition switch to the ON posi-
tion to start cranking the engine. After 5
or 6 seconds, stop cranking by pushing
the ignition switch to OFF. After cranking
the engine, release the accelerator pedal.
Crank the engine with your foot off the accelerator pedal
by depressing the brake
pedal and pushing the push-button igni-
tion switch to start the engine. If the
engine starts, but fails to run, repeat the
above procedure.
CAUTION
Do not operate the starter for more than 15
seconds at a time. If the engine does not start,
push the ignition switch to OFF and wait 10
seconds before cranking again, otherwise the
starter could be damaged.
4. Warm-up
Allow the engine to idle for at least 30
seconds after starting. Do not race the en-
gine while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather. In cold weather, keep the
engine running for a minimum of 2 - 3
minutes before shutting it off. Starting and
stopping the engine over a short period of
time may make the vehicle more difficult to
start.
When racing the engine up to 4,000 rpm or
more under the no load condition, the en-
gine will enter the fuel cut mode.

Starting and driving5-13

5. To stop the engine, shift the selector leverto the P (Park) position and push the
ignition switch to the OFF position.ENGINE PROTECTION MODE
The engine has an engine protection mode to
reduce the chance of damage if the coolant
temperature becomes too high (for example,
when climbing steep grades in high tempera-
ture with heavy loads, such as when towing a
trailer).
When the engine temperature reaches a certain
level:
● The engine coolant temperature gauge will
move toward the H position.
● Engine power may be reduced.
● The air conditioning cooling function may be
automatically turned OFF for a short time
(the blower will continue to operate).
Engine power and, under some conditions, ve-
hicle speed will decrease. Vehicle speed can be
controlled with the accelerator pedal, but the
vehicle may not accelerate at the desired
speed. The transmission will downshift or up-
shift as it reaches prescribed shift points. You
can also shift manually.
As driving conditions change and engine cool-
ant temperature is reduced, vehicle speed can
be increased using the accelerator pedal, and
air conditioning cooling function will automati-
cally be turned back ON. If:1. The engine coolant temperature is not
reduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant tem-
perature gauge does not return to the
normal range from the H position, this
may indicate a malfunction. Move the
vehicle off the road to a safe area and
allow the engine to cool. If after checking
the oil and coolant, the
remains on
or engine coolant temperature does not
return to the normal range, do not con-
tinue to drive and contact an INFINITI
retailer.
The Malfunction Indicator Light (MIL)may also come ON. You do not need to have
your vehicle towed, unless it remains on, but
have it inspected soon by an INFINITI retailer.
