Pre-driving checks and adjustments3-23

1. Pull the hood lock release handle1lo-
cated below the driver side instrument
panel. The hood will spring up slightly.
2. Push the lever
2at the front of the
hood to the side 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. 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.
WARNING
∙ Always be sure the liftgate has beenclosed 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. For additional
information, refer to “Exhaust gas (car-
bon monoxide)” in the “Starting and driv-
ing” section of this manual.
∙ 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 children,
people who require the assistance of oth-
ers 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 signifi-
cant risk of injury or death to people and
pets.
∙ Always be sure that hands and feet are clear of the door frame to avoid injury
while closing the liftgate.

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 po- sition 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 inter-
ference) 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,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.
2. Press the Park button to place the ve-
hicle 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 de-
pressing the brake pedal with the ignition
switch in any position.
∙ If the engine is very hard to start in extremely cold weather or when re-
starting, 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 be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch to
the ON position to start cranking the
engine. After 5 or 6 seconds, stop
cranking by pushing the ignition switch
