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 automated toll road device or
automatic payment device on the key ring) , restart
the engine using the following procedure:
1. Leave the ignition switch in the ON position
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 device
(which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN recom-
mends 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 and clutch fluid, and window
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.
●Lock all doors.
●Position seat and adjust head restraints.
●Adjust inside and outside mirrors.
●Fasten seat belts and ask all passengers to
do likewise.
●Check the operation of warning lights when
the key is turned to the ON (3) position. See
“Warning/indicator lights and audible re-
minders” in the “Instruments and controls”
section of this manual.1. Apply the parking brake.
2.CVT model:
Move the shift selector to P (Park) or N
(Neutral) . P (Park) is recommended.
The shift selector cannot be moved out
of P (Park) and into any of the other
gear positions if the ignition key is
turned to the OFF position or if the key
is removed from the ignition switch.
The starter is designed not to operate if
the shift selector is in any of the driving
positions.
Manual transmission model:
Move the shift selector to N (Neutral) . De-
press the clutch pedal to the floor while
cranking the engine.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
Models with Intelligent Key:Slowly
“PUSH ON” the ignition switch. When the
Intelligent Key warning light
in the
meter illuminates in green, the ignition
switch can be turned.
The Intelligent Key must be carried
when operating the ignition switch.

WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually reduced.
The reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially care-
ful when driving. If necessary, pull to the
side of the road at a safe place and allow
the transmission to return to normal op-
eration, or have it repaired if necessary.
MANUAL TRANSMISSION (if so
equipped)
WARNING
●Do not downshift abruptly on slippery
roads. This may cause a loss of control.
●Do not over-rev the engine when shift-
ing to a lower gear. This may cause a
loss of control or engine damage.
CAUTION
●Do not rest your foot on the clutch pedal
while driving. This may cause clutch
damage.
●Fully depress the clutch pedal before
shifting to help prevent transmission
damage.
●Stop your vehicle completely before
shifting into R (Reverse) .
●When the vehicle is stopped with the
engine running (for example, at a stop
light) , shift to N (Neutral) and release
the clutch pedal with the foot brake
applied.
Shifting
To change gears or when upshifting or down-
shifting, depress the clutch pedal fully, shift into
the appropriate gear, then release the clutch
slowly and smoothly.
To ensure smooth gear changes, fully depress
the clutch pedal before operating the shift selec-
tor. If the clutch pedal is not fully depressed
before the transmission is shifted, a gear noise
may be heard. Transmission damage may occur.
Start the vehicle in 1st gear and shift to 2nd, 3rd,
4th and 5th up to 6th gear in sequence according
to vehicle speed.

(Neutral) position.
If it is difficult to move the shift selector into R
(Reverse) or 1 (1st) , shift into N (Neutral) , then
release the clutch pedal. Depress the clutch
pedal again and shift into R (Reverse) or 1 (1st) .
Suggested upshift speeds
The following are suggested vehicle speeds for
shifting into a higher gear. These suggestions
relate to fuel economy and vehicle performance.

conditions, the weather and individual driving
habits.
GEAR CHANGE MPH (km/h)
1st to 2nd 8 (13)
2nd to 3rd 17 (27)
3rd to 4th 25 (40)
4th to 5th 36 (58)
5th to 6th 51 (82)
Suggested maximum speed in each
gear
Downshift to a lower gear if the engine is not
running smoothly, or if you need to accelerate.
Do not exceed the maximum suggested speed
(shown below) in any gear. For level road driving,
use the highest gear suggested for that speed.
Always observe posted speed limits, and drive
according to the road conditions, which will en-
sure safe operation. Do not over-rev the engine

and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimesMake sure all
warning lights and chimes are operating properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
MIN and MAX lines on the reservoir.Engine coolant level*Check the coolant level
when the engine is cold.
Engine drive belts*Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level*Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust systemMake sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Fluid leaksCheck under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield washer fluid*Check that there is
adequate fluid in the reservoir.
