Lockout protection
When the power door lock switch (driver’s or
front passenger’s side) is moved to the lock
position with the key in the ignition and any door
open, all doors will lock and then unlock auto-
matically. This helps to prevent the keys from
being accidently locked inside the vehicle.
CHILD SAFETY REAR DOOR LOCK
Child safety locks help prevent the rear doors
from being opened accidentally, especially when
small children are in the vehicle.
The child safety lock levers are located on the
edge of the rear doors.
When the lever is in the unlock position
s1, the
door can be opened from the outside or the
inside.
When the lever is in the lock position
s2,
the door can be opened only from the out-
side.It is possible to lock/unlock all doors, turn the
interior lights on, and activate the panic alarm by
using the keyfob from outside the vehicle.
Be sure to remove the key from the vehicle
before locking the doors.
The keyfob can operate at a distance of approxi-
mately 33 ft (10 m) from the vehicle. The effective
distance depends on the conditions around the
vehicle.
As many as 5 keyfobs can be used with one
vehicle. For information concerning the purchase
and use of additional keyfobs, contact a NISSAN
dealer.
The keyfob will not function when:
cthe battery is discharged
cthe distance between the vehicle and the
keyfob is over 33 ft (10 m)
The panic alarm will not activate when the
key is in the ignition switch.
CAUTION
Listed below are conditions or occur-
rences which will damage the keyfob:
cDo not allow the keyfob to become wet.
cDo not drop the keyfob.

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.
