NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment 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
10 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, NISSAN
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. 2-12). 1. Apply the parking brake.
2. Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
unless the shif t lever is in either P
(Park) or N (Neutral).
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 igni-
tion 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 en-
gine. 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. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition
switch to the LOCK position. Af ter
BEFORE STARTING THE ENGINE STARTING THE ENGINE
5-16Starting and driving

cranking the engine, release the accel-
erator pedal. Crank the engine with
your foot off the accelerator pedal by
depressing the brake pedal and push-
ing the ignition switch to start the en-
gine. 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 the OFF position 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 af ter starting. Do not race the
engine while warming it up. Drive at a
moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of 2 to 3 minutes before shut-
ting it off. Starting and stopping the en-
gine over a short period of time may
make the vehicle more difficult to start. 5. To stop the engine, move the shif t lever
to the P (Park) position and push the
ignition switch to the OFF position.
In preparation for the next engine start, the
engine may have a slightly delayed shutoff
af ter placing the ignition switch in the OFF
position, depending on the driving condi-
tions.NOTE:
Care should be taken to avoid situa-
tions that can lead to potential bat-
tery discharge and potential no-start
conditions such as:
1. Installation or extended use of elec- tronic accessories that consume bat-
tery power when the engine is not
running (phone chargers, GPS, DVD
players, etc.).
2. The vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
REMOTE ENGINE START (if so
equipped)
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t
lever can be moved from the P (Park) posi-
tion. To place the ignition switch in the ON
position, follow these steps:
1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Push the ignition switch once to the ON position.
For additional information, see “NISSAN In-
telligent Key®” (P. 3-2).

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 temperatures with heavy loads,
such as when towing a trailer). When the
engine temperature reaches a certain
level:
• The engine coolant temperature gaugewill 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,
vehicle 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
downshif t or upshif t as it reaches pre-
scribed shif t points. You can also shif t
manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accel-
erator pedal, and the air conditioning cool-
ing function will automatically be turned
back on. The Malfunction Indicator Light (MIL) may
also come on if the engine coolant tem-
perature is not reduced or the air condi-
tioning cooling function does not turn back
on. If
only it remains on, you do not need to
have your vehicle towed, but have it in-
spected soon. It is recommended that you
visit a NISSAN dealer for this service. For
additional information, see “Malfunction In-
dicator Light (MIL)” (P. 2-20).
WARNING
Overheating can result in reduced en-
gine power and vehicle speed. The re-
duced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful
when driving. If the vehicle cannot
maintain a safe driving speed, pull to
the side of the road in a safe area. Allow
the engine to cool and return to normal
operation. For additional information,
see “If your vehicle overheats” (P. 6-12).
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.
AUTOMATIC TRANSMISSION (A/T)
WARNING
• Do not depress the accelerator pedal
while shif ting from P (Park) or N (Neu-
tral) to R (Reverse) or D (Drive). Always
depress the brake pedal until shif ting
is completed. Failure to do so could
cause you to lose control and have an
accident.
• Cold engine idle speed is high, so use
caution when shif ting into a forward
or reverse gear before the engine has
warmed up.
• Never shif t to either the P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is
reversing. This could cause an acci-
dent or damage the transmission.
DRIVING THE VEHICLE
