SYSTEM MAINTENANCE
The sensor for the I-DC systemis
located below the front bumper.
The I-DC system is designed to automa-
tically check the sensor’s operation. When
the sensor is covered with dirt or is
obstructed, the system will automatically
be canceled. If the sensor is covered with
ice, a transparent or translucent vinyl bag,
etc., the I-DC system may not detect
them. In these instances, the I-DC system
may not be able to decelerate the vehicle
properly. Be sure to check and clean the
sensor regularly.
To keep the I-DC system operating prop-
erly, be sure to observe the following:

WARNING
.The sonar system is a conveni-
ence but it is not a substitute for
proper parking. Always look
around and check that it is safe
to do so before parking. Always
move slowly.
. Read and understand the limita-
tions of the sonar system as
contained in this section. Incle-
ment weather may affect the
function of the sonar system; this
may include reduced perfor-
mance or a false activation. .
This system is not designed to
prevent contact with small or
moving objects.
. The system is designed as an aid
to the driver in detecting large
stationary objects to help avoid
damaging the vehicle. The sys-
tem will not detect small objects
below the bumper, and may not
detect objects that are too close
to the bumper or on the ground.
. If your vehicle sustains damage
to the bumper fascia, leaving it
misaligned or bent, the sensing
zone may be altered causing in-
SNOW MODE SONAR SYSTEM (if so equipped)

faces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire
chains. Always maintain a safe
distance from the vehicle in front
of you. Ultimately, the driver is
responsible for safety.
. Tire type and condition may also
affect 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 Informa-
tion label. See “Tire and load-
ing information label” (P.10-
12).
— For detailed information, see “Wheels and tires” (P.8-30).
The Anti-lock Braking System (ABS) con-
trols 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 prevent each
wheel from locking and sliding. By pre-
venting 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 ABS will operate to prevent the
wheels from locking up. Steer the vehicle
to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing
so may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, elec-
tric 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 malfunc-
tion. 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. It is recommended you
visit a NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h). The speed varies
according to road conditions.
When the ABS senses that one or more
wheels are close to locking up, the
actuator rapidly applies and releases
hydraulic pressure. 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 operating. This is normal and indicates
that the ABS is operating properly. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.

5-140Starting and driving
Push the VDC OFF switch again or restart
the engine to turn ON the system.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing,
apply deicer through the key hole. If the
lock becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that
the outside temperature will drop below
32°F (0°C), check antifreeze to assure
proper winter protection. For additional
information, see “Engine cooling system”
(P.8-4).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P.8-11).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-4).
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON tires on all four
wheels. It is recommended you consult a
NISSAN dealer for the tire type, size, speed
rating and availability information.
For additional traction on icy roads,
studded tires may be used. However,
some U.S. states and Canadian provinces
prohibit their use. Check local, state and
provincial laws before installing studded
tires.
Skid and traction capabilities of
studded snow tires, on wet or dry
surfaces, may be poorer than that of
non-studded snow tires.
Tire chains may be used. For details, see
“Tire chains” (P.8-37).
COLD WEATHER DRIVING

To shut off the engine in an emergency
situation while driving, perform the fol-
lowing procedure:
.Rapidly push the push-button ignition
switch 3 consecutive times in less
than 1.5 seconds, or
. Push and hold the push-button igni-
tion switch for more than 2 seconds.TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears in the vehicle
information display, one or more of your
tires is significantly under-inflated. If the
vehicle is being driven with low tire
pressure, the TPMS will activate and warn
you of it by the low tire pressure warning
light. This system will activate only when
the vehicle is driven at speeds above 16
MPH (25 km/h). For more details, see “Low
tire pressure warning light” (P.2-15) and
“Tire Pressure Monitoring System (TPMS)”
(P.5-5).
WARNING
.If the low tire pressure warning
light illuminates or Low Pressure
information is displayed on the
monitor screen while driving,
avoid sudden steering maneu-
vers or abrupt braking, reduce
vehicle speed, pull off the road
to a safe location and stop the
vehicle as soon as possible. Driv-
ing with under-inflated tires may permanently damage the tires
and increase the likelihood of tire
failure. Serious vehicle damage
could occur and may lead to an
accident and could result in ser-
ious personal injury. Check the
tire pressure for all four tires.
Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low
tire pressure warning light OFF. If
the light still illuminates while
driving after adjusting the tire
pressure, a tire may be flat. If
you have a flat tire, replace it with
a spare tire as soon as possible.
. Since the spare tire is not
equipped with the TPMS, when a
spare tire is mounted or a wheel
is replaced, the TPMS will not
function and the low tire pressure
warning light will flash for ap-
proximately 1 minute. The light
will remain on after 1 minute.
Have your tires replaced and/or
TPMS system reset as soon as
possible. It is recommended you
visit a NISSAN dealer for these
services.
