REMOTE ENGINE START
OPERATING RANGE
WARNING
• To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, including en-
trapment in windows or inadvertent
door lock activation, do not leave chil-
dren, people who require the assistance
of others or pets unattended in your vehicle. Additionally, the temperature
inside a closed vehicle on a warm day can
quickly become high enough to cause a
significant risk of injury or death to
people and pets.
• Do not use Remote Engine Start in closed
spaces such as a garage. Do not breathe
exhaust gases; they contain colorless
and odorless carbon monoxide. Carbon
monoxide is dangerous. It can cause un-
consciousness or death.
CAUTION
When the Intelligent Key battery is dis-
charged or other strong radio wave
sources are present near the operating lo-
cation, the Intelligent Key operating range
becomes narrower, and the Intelligent Key
may not function properly.
The Remote Engine Start function can only
be used when the Intelligent Key is within the
specified operating range from the vehicle.
The Remote Engine Start operating range is
approximately 197 ft (60 m) from the vehicle.

Pre-driving checks and adjustments3-19

EXTENDING ENGINE RUN TIME
The Remote Engine Start feature can be ex-
tended one time by performing the steps listed
in “Remote starting the vehicle” (P. 3-19). Run
time will be calculated as follows:
• The first 10 minute run time will startwhen the Remote Engine Start function is
performed.
• The second 10 minutes will start immedi- ately when the Remote Engine Start func-
tion is performed again. For example, if the
engine has been running for 5 minutes, and
10 minutes are added, the engine will run
for a total of 15 minutes.
• Extending engine run time will bring you to the two Remote Engine Start limit.
A maximum of two Remote Engine Starts, or
a single start with an extension, are allowed
between ignition cycles.
The ignition switch must be cycled to the ON
position and then back to the OFF position
before the Remote Engine Start procedure

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. •
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. 10-4).
•
The Loose Fuel Cap warning message will
be displayed if the fuel-filler cap is not
properly tightened. It may take a few driv-
ing trips for the message to be displayed.
Failure to tighten the fuel-filler cap prop-
erly after the Loose Fuel Cap warning
is displayed may cause the Malfunction
Indicator Light (MIL) to illuminate.
• Failure to tighten the fuel-filler cap
properly may cause theMalfunc-
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
retailer for this service.
Pre-driving checks and adjustments3-29

INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll
road device or automated payment device on
the key ring. Restart the engine using the
following procedures:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position and wait approximately
5 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the interfer-
ence) separate from the registered key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-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.
• Check that all doors are closed.
• 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 placed in the ON
position. For additional information, see
“Warning lights, indicator lights and audible
reminders” (P. 2-9) 1. Apply the parking brake.
2. Press the Park button to place the vehicle
in P (Park) or move the shift lever to N
(Neutral). P (Park) is recommended.
The starter is designed not to operate if
the shift lever is in any of the driving
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 depress-

5-16Starting and driving

If the vehicle is driven under extreme condi-
tions, such as excessive wheel spinning and
subsequent hard braking, the fail-safe sys-
tem may be activated. The Malfunction Indi-
cator Light (MIL) may come on to indicate
the fail-safe mode is activated. For addi-
tional information, see “Malfunction Indica-
tor Light (MIL)” (P. 2-15). This will occur
even if all electrical circuits are functioning
properly. In this case, place the ignition
switch in the OFF position and wait for
10 seconds. Then place the ignition switch
back in the ON position. The vehicle should
return to its normal operating condition. If it
does not return to its normal operating con-
dition, have the transmission checked and re-
paired, if necessary. It is recommended that
you visit an INFINITI retailer for this service.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs, ve-
hicle speed may be gradually reduced. The
reduced speed may be lower than other
traffic, which could increase the chance of
a collision. Be especially careful when driv-
ing. If necessary, pull to the side of the road
at a safe place and allow the transmission
to return to normal operation, or have it
repaired if necessary.
WARNING
• Be sure the parking brake is fully re-
leased before driving. Failure to do so
can cause brake failure and lead to an
accident.
• Do not release the parking brake from
outside the vehicle.
• Do not use the shift lever in place of the
parking brake. When parking, be sure the
parking brake is fully engaged. •
To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm day
can quickly become high enough to cause
a significant risk of injury or death to
people and pets.
The electronic parking brake can be applied
or released automatically or by operating the
parking brake switch.
AUTOMATIC OPERATION
The electronic parking brake is automatically
released as soon as the vehicle starts and the
accelerator pedal is depressed.

WHEN TOWING A TRAILER
Depending on the weight of the vehicle and
trailer and the steepness of the slope, there
may be a tendency for the vehicle to move
backwards when starting from a standstill.
When this occurs, you can use the parking
brake switch in the same way as a conven-
tional lever type parking brake.
Before starting on sloping roads when tow-
ing a trailer, be sure to read the following to
prevent the vehicle from moving backwards
unintentionally.
• Release the parking brake switch as soonas the engine is delivering enough torque to
the wheels. The automatic brake hold function maintains
the braking force without the driver having to
depress the brake pedal when the vehicle is
stopped at a traffic light or intersection. As
soon as the driver depresses the accelerator
pedal again, the automatic brake hold func-
tion is deactivated and the braking force is
released. The operating status of automatic
brake hold can be displayed.
To use the automatic brake hold function, the
following conditions need to be met:
• The driver’s seat belt is fastened.
• The electronic parking brake is released.
