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 procedure:
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 and clutch fluid (if so equipped),
and windshield-washer fluid as fre-
quently 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/ 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.
Continuously Variable Transmission
model:
Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
if the shif t lever is in any of the driving
positions.
Manual Transmission (M/T) model:
Move the shif t lever to N (Neutral). De-
press the clutch pedal to the floor.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and the
clutch pedal (if so equipped) 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
BEFORE STARTING THE ENGINE STARTING THE ENGINE
5-14Starting and driving

M1 (1st)
Use this position when climbing steep hills
slowly or driving slowly through deep snow,
sand or mud, or for maximum engine brak-
ing on steep downhill grades.
• Remember not to drive at high speeds forextended periods of time in lower than
the 6th range. This reduces fuel economy.
When shif ting up
Move the shif t lever to the + (up) side. (Shif ts
to higher range.)
When shif ting down
Move the shif t lever to the − (down) side.
(Shif ts to lower range.)
• Moving the shif t lever rapidly to the same side twice will shif t the ranges in succes-
sion.
• The transmission will automatically downshif t the gears. (For example, if you
select the 3rd range, the transmission will
shif t down between the 3rd and 1st
gears.)
When canceling the manual shif t mode
Return the shif t lever to the D (Drive) posi-
tion to return the transmission to the nor-
mal driving mode. •
In the manual shif t mode, the trans-
mission may not shif t to the selected
gear. This helps maintain driving per-
formance and reduces the chance of
vehicle damage or loss of control.
• When this situation occurs, the Con-
tinuously Variable Transmission (CVT)
position indicator light will blink and
the chime will sound.
• In the manual shif t mode, the trans-
mission may shif t up automatically to a
higher range than selected if the en-
gine speed is too high. When the ve-
hicle speed decreases, the transmis-
sion automatically shif ts down and
shif ts to 1st gear before the vehicle
comes to a stop.
• CVT operation is limited to automatic drive mode when CVT fluid temperature
is extremely low even if manual shif t
mode is selected. This is not a malfunc-
tion. When CVT fluid warms up, manual
mode can be selected.
• When the CVT fluid temperature is high, the shif t range may upshif t in lower rpm
than usual. This is not a malfunction.
Shif t lock release
If the battery charge is low or discharged,
the shif t lever may not be moved from the
P (Park) position even with the brake pedal
depressed and the shif t lever button
pressed.
It will be necessary to jump start or have
your battery charged. For additional infor-
mation, refer to “Jump starting” in the “In
case of emergency” section of this manual.
It is recommended that you contact a
NISSAN dealer or a professional towing ser-
vice.

•Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
– When installing a spare tire, make
sure that it is the proper size and
type as specified on the Tire and
Loading Information label. For ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer in-
formation” section of this manual.
– For additional information, refer
to “Wheels and tires” in the “Do-it-
yourself ” section of this manual.
The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.

CAUTION
• NISSAN recommends using Genuine
NISSAN CVT Fluid NS-3 (or equiva-
lent) ONLY in NISSAN CVTs. Do not mix
with other fluids.
• Do not use Automatic Transmission
Fluid (ATF) or manual transmission
fluid in a NISSAN CVT, as it may dam-
age the CVT. Damage caused by the
use of fluids other than as recom-
mended is not covered under
NISSAN's New Vehicle Limited
Warranty.
• Using fluids that are not equivalent
to Genuine NISSAN CVT Fluid NS-3
may also damage the CVT. Damage
caused by the use of fluids other than
as recommended is not covered un-
der NISSAN's New Vehicle Limited
Warranty.
When checking or replacement of CVT fluid
is required, it is recommended that you visit
a NISSAN dealer for servicing. For additional brake and clutch fluid speci-
fication information, refer to “Recom-
mended fluids/lubricants and capacities”
in the “Technical and consumer informa-
tion” section of this manual.
CAUTION
Do not spill the fluid on any painted sur-
faces. This will damage the paint. If fluid
is spilled, immediately wash the sur-
face with water.
BRAKE FLUID
Check the fluid level in the reservoir. If the
level is below the MIN line
O1, or the brake
warning light comes on, add Genuine
NISSAN Brake Fluid or equivalent DOT 3
fluid up to the MAX line
O2. If fluid must be
added frequently, the system should be
checked. It is recommended that you visit a
NISSAN dealer for this service.

CLUTCH (if so equipped) FLUID
Check the fluid level in the reservoir. If the
level is below the MIN line
O1, or the brake
warning light comes on, add Genuine
NISSAN Brake Fluid or equivalent DOT 3
fluid up to the MAX line
O2. If fluid must be
added frequently, the system should be
checked. It is recommended that you visit a

WINDSHIELD-WASHER FLUID
RESERVOIR
Fill the windshield-washer fluid reservoir
periodically. Add windshield-washer fluid
when the low windshield-washer fluid
warning light (if so equipped) comes on or
the “Low Washer Fluid” warning message
shows on the vehicle information display.
To check the fluid level, use your finger to
plug the center hole
O1of the cap/tube
assembly, then remove it from the reser-
voir. If there is no fluid in the tube, add fluid.
Add a washer solvent to the washer for
better cleaning. In the winter season, add a windshield washer antifreeze. Follow the
manufacturer's instructions for the mix-
ture ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of windshield-washer fluid.
Recommended fluid is Genuine NISSAN
Windshield Washer Concentrate Cleaner &
Anti-freeze or equivalent.
