below the driver side instrument panel. The
hood will spring up slightly.
2Push the lever at the front of the hood to the
side as illustrated with your fingertips and
raise the hood.
When closing the hood, lower it slowly and make
sure it locks into place.
WARNING
● Make sure the hood is completely
closed and latched before driving. Fail-
ure to do so could cause the hood to fly
open and result in an accident.
● If you see steam or smoke coming from
the engine compartment, to avoid injury
do not open the hood.
WARNING
●Always be sure the liftgate has been
closed securely to prevent it from open-
ing while driving.
● Do not drive with the liftgate open. This
could allow dangerous exhaust gases
to be drawn into the vehicle. See “Ex-
haust gas” in the “Starting and driving”
section of this manual.
● Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended

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.
Always 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
automatically. 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
possible 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 fill-
ing it.
– Use only approved portable fuel con- tainers for flammable liquid.
CAUTION
●Do not use E-15 or E-85 fuel in your
vehicle. For further information see the
“Fuel Recommendation” in the “Techni-
cal and consumer information” section
of this manual. ●
The LOOSE FUEL CAP warning will ap-
pear 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 ap-
pears may cause the
Malfunction
Indicator Light (MIL) to illuminate.
● 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 the
light does not turn off after a
few driving trips, have the vehicle in-
spected by an INFINITI retailer.
● For additional information, see the
“Malfunction Indicator Light (MIL)” in
the “Instruments and Controls” section
in this manual.
● If fuel is spilled on the vehicle body,
flush it away with water to avoid paint
damage.

RADIO
Place the ignition switch in the ACC or ON
position and press the VOL (volume)/ON·OFF
(power) knob to turn the radio on. If you listen to
the radio with the engine not running, the ignition
switch should be placed in the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external influ-
ences. Intermittent changes in reception quality
normally are caused by these external influences.
Using a cellular phone in or near the ve-
hicle may influence radio reception quality.
Radio reception
Your INFINITI radio system is equipped with
state-of-the-art electronic circuits to enhance ra-
dio reception. These circuits are designed to
extend reception range, and to enhance the qual-
ity of that reception.
However, there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle, even
when the finest equipment is used. These char-
acteristics are completely normal in a given re-
ception area, and do not indicate any malfunction
in your INFINITI radio system.Reception conditions will constantly change be-
cause of vehicle movement. Buildings, terrain,
signal distance and interference from other ve-
hicles can work against ideal reception. De-
scribed below are some of the factors that can
affect your radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the de-
vice in a different location may reduce or elimi-
nate the noise.
FM RADIO RECEPTION
Range: FM range is normally limited to 25 – 30 mi
(40 – 48 km) , with monaural (single channel) FM
having slightly more range than stereo FM. Exter-
nal influences may sometimes interfere with FM
station reception even if the FM station is within
25 mi (40 km) . The strength of the FM signal is
directly related to the distance between the
transmitter and receiver. FM signals follow a line-
of-sight path, exhibiting many of the same char-
acteristics as light. For example, they will reflect
off objects.
Fade and drift: As your vehicle moves away from
a station transmitter, the signals will tend to fade
and/or drift.
Static and flutter: During signal interference from
buildings, large hills or due to antenna position
(usually in conjunction with increased distance
from the station transmitter) , static or flutter can
be heard. This can be reduced by adjusting the
treble control to reduce treble response.
Multipath reception: Because of the reflective
characteristics of FM signals, direct and reflected
signals reach the receiver at the same time. The
signals may cancel each other, resulting in mo-
mentary flutter or loss of sound.
AM RADIO RECEPTION
AM signals, because of their low frequency, can
bend around objects and skip along the ground.
In addition, the signals can be bounced off the
ionosphere and bent back to earth. Because of
these characteristics, AM signals are also sub-
ject to interference as they travel from transmitter
to receiver.
Fading: Occurs while the vehicle is passing
through freeway underpasses or in areas with
many tall buildings. It can also occur for several
seconds during ionospheric turbulence even in
areas where no obstacles exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic lights.
