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,
see “Warning lights, indicator lights and
audible reminders” (P. 2-9). 1. Apply the parking brake.

Drive sport mode switch
To select the drive sport mode, push the
drive sport mode switch with the shif t lever
in the D (Drive) position.
The drive sport mode indicator in the ve-
hicle information display illuminates next
to the Transmission Shif t Position indicator.
To turn off the drive sport mode, push the
drive sport mode switch again. The drive
sport mode indicator will turn off. When the
shif t lever is shif ted to any position other
than D (Drive), the drive sport mode will be
automatically turned off.OFF position:
For normal driving and fuel economy, use
the OFF position.
ON position:
For driving up or down long slopes where
engine braking is necessary, or for powerful
acceleration, use the ON position. The
transmission will automatically select a dif-
ferent gear ratio, allowing the engine to
provide high output.
Remember not to drive at high speeds for
extended periods of time with the drive
sport mode in the ON position. This re-
duces fuel economy.Accelerator downshif t
— in D (Drive) position —
For passing or hill climbing, depress the
accelerator pedal to the floor. This shif ts
the transmission down into a lower gear,
depending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
when climbing steep grades in high tem-peratures with heavy loads, such as when
towing a trailer), engine power and, under
some conditions, vehicle speed will be de-
creased automatically to reduce the
chance of transmission damage. Vehicle
speed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be limited.
Fail-safe
If the vehicle is driven under extreme
conditions, such as excessive wheel
spinning and subsequent hard braking,
the fail-safe system may be activated.
The Malfunction Indicator Light (MIL)
may come on to indicate the fail-safe
mode is activated. For additional infor-
mation, see “Malfunction Indicator Light
(MIL)” (P. 2-11). This will occur even if all
electrical circuits are functioning prop-
erly. In this case, place the ignition switch
in the OFF position and wait for 10 sec-
onds. Then push the switch back to the
ON position. The vehicle should return to
its normal operating condition. If it does
not return to its normal operating condi-
tion, have the transmission checked and
repaired, if necessary. It is recommended
that you visit a NISSAN dealer for this
service.
