3-16Pre-driving checks and adjustments

Thebutton will be on the NISSAN
Intelligent Key® if the vehicle has Remote
Engine Start. This feature allows the engine
to start from outside the vehicle.
The following features may be affected
when the Remote Engine Start feature is
used:
• Vehicles with a manual climate control system will default to the last used heat-
ing or cooling mode. • Vehicles with an automatic climate con-
trol system may default to either a heat-
ing or cooling mode depending on out-
side and cabin temperatures. For
additional information, see “Remote En-
gine Start with Intelligent Climate Control”
(P. 4-41).
Laws in some local communities may re-
strict or prohibit the use of the Remote
Engine Start, or the amount of time a
parked engine may idle. For example, some
laws require a person using Remote Engine
Start to have the vehicle in view or may
restrict idling time except in freezing tem-
peratures. Check local regulations for any
requirements.
Other conditions may affect the function of
the Remote Engine Start feature. For addi-
tional information, see “Conditions the Re-
mote Engine Start will not work” (P. 3-20).
Other conditions can affect the perfor-
mance of the Intelligent Key transmitter.
For additional information, see “NISSAN In-
telligent Key®” (P. 3-7).
REMOTE ENGINE START
OPERATING RANGE
WARNING
• To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant 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 con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconscious-
ness or death.

3-18Pre-driving checks and adjustments

CAUTION
When the Intelligent Key battery is dis-
charged or other strong radio wave
sources are present near the operating
location, the Intelligent Key operating
range becomes narrower, and the Intel-
ligent 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 f t (60 m) from the
vehicle.
REMOTE STARTING THE VEHICLE
To use the Remote Engine Start feature to
start the engine perform the following:
1. Aim the Intelligent Key at the vehicle.
2. Press the
button to lock all doors.
3. Within 5 seconds press and hold the
button until the turn signal lights
flash and the tail lamps turn on. If the
vehicle is not within view press and hold
the
button for at least 2 seconds. The following events will occur when the
engine starts:
• The parking lights will turn on and remain
on as long as the engine is running.
• The doors will be locked and the climate control system may come on.
• The engine will continue to run for 10 min- utes. Repeat the steps to extend the time
for an additional 10 minutes. For addi-
tional information, see “Extending engine
run time” (P. 3-19).
Press and hold the brake then push the
push-button ignition switch to the ON po-
sition before driving. For additional infor-
mation, see “Driving the vehicle” (P. 5-16).
EXTENDING ENGINE RUN TIME
The Remote Engine Start feature can be
extended 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 start when the Remote Engine Start function is
performed. • The second 10 minutes will start af ter the
first Remote Engine Start request ends.
For example, if the engine has been run-
ning for 5 minutes, and 10 minutes are
added, the engine will run for a total of 20
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 al-
lowed between ignition cycles.
The vehicle needs to be driven at speeds of
4 mph (7 km/h) before the Remote Engine
Start procedure can be used again.

3-20Pre-driving checks and adjustments

1. Pull the hood lock release handleO1lo-
cated on the lower door pillar until the
hood springs up slightly.
2. Locate the lever
O2in between the hood
and grille and push the lever sideways
with your fingertips.
3. Raise the hood
O3.
4. Remove the support rod
O4and insert it
into the slot marked by an arrow.
NOTE:
Do not place the support rod in a location
other than the designated slot. Hold the coated parts when removing or
resetting the support rod. Avoid direct
contact with the metal parts, as they
may be hot immediately af ter the engine
has been stopped.
When closing the hood, return the support
rod to its original position, lower the hood
to approximately 12 in (30 cm) above the
latch and release it. This allows proper en-
gagement of the hood latch.
WARNING
• Make sure the hood is completely
closed and latched before driving.
Failure 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.

FUEL-FILLER CAP
WARNING
• Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seri-
ously injured if it is misused or mis-
handled. 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 af ter 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 emission control system. An in-
correct cap can result in a serious
malfunction and possible injury. It
could also cause the
Malfunc-
tion 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
containers for flammable liquid.
CAUTION
• Do not use E–15 or E–85 fuel in your
vehicle. For additional information,
see “Fuel recommendation” (P. 10-4). •
The LOOSE FUEL CAP warning mes-
sage 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 af ter the
LOOSE FUEL CAP warning message
appears may cause the
Mal-
function Indicator Light (MIL) to
illuminate.
• Failure to tighten the fuel-filler cap
properly may cause the
Mal-
function Indicator Light (MIL) to illu-
minate. 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 af ter a few
driving trips. If thelight does not
turn off af ter a few driving trips, have
the vehicle inspected. It is recom-
mended that you visit a NISSAN
dealer for this service.
• For additional information, see “Mal-
function Indicator Light (MIL)”
(P. 2-11).
• If fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage.
