WARNING
Never remove or turn the key to the LOCK
position while driving. The steering wheel
will lock. This may cause the driver to lose
control of the vehicle and could result in
serious vehicle damage or personal injury.
INTELLIGENT KEY SYSTEM (if so
equipped)
The Intelligent Key system can operate the igni-
tion switch without taking the key out from your
pocket or purse. The operating environment
and/or conditions may affect the Intelligent Key
system operation.
CAUTION
cBe sure to carry the Intelligent Key with
you when operating the vehicle.
cNever leave the Intelligent Key inside
the vehicle when you leave the vehicle.
cIf the vehicle battery is discharged the
ignition switch cannot be moved from
the “LOCK” position and if the steering
lock is engaged, the steering wheel
cannot be moved. Charge the battery as
soon as possible. (See “JUMP START-
ING” in the “In case of emergency” sec-
tion of this manual.)

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) .
When the ABS senses that one or more wheels
are close to locking up, the system electronically
controls the pressure applied to each brake.
This action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is oper-
ating. This is normal and indicates that the ABS is
operating properly. However, the pulsation may
indicate that road conditions are hazardous and
extra care is required while driving.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply de-
icer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the key
hole or use the remote keyless entry keyfob (if so
equipped) .
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and do-it-yourself” section of this
manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance and do-it-yourself” section of this
manual.

WARNING
cAlways make sure that the spare tire
and jacking equipment are properly se-
cured after use. Such items can become
dangerous projectiles in an accident or
sudden stop.
cThe spare tire is designed for emer-
gency use. See specific instructions un-
der the heading “Wheels and tires” in
the “Maintenance and do-it-yourself”
section of this manual.To start your engine with a booster battery, the
instructions and precautions below must be fol-
lowed.
WARNING
cIf done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also
damage your vehicle.
cExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
cDo not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a cor-
rosive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted area with
water.
cKeep battery out of the reach of
children.
cThe booster battery must be rated at 12
volts. Use of an improperly rated battery
can damage your vehicle.cWhenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
cDo not attempt to jump start a frozen
battery. It could explode and cause se-
rious injury.
cYour vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
cIf the battery of a vehicle equipped with
the Intelligent Key system is dis-
charged, the ignition switch cannot be
moved from the LOCK position, even
using the mechanical key or the valet
key. Connect the jumper cables to an-
other vehicle, as in the case of a dis-
charged battery, and then the ignition
knob can be moved from the LOCK po-
sition. Then, jump start the vehicle.
