accurate measurement of obsta-
cles or false alarms.
CAUTION
Keep the interior of the vehicle as
quiet as possible to hear the tone
clearly.
The sonar system sounds a tone to warn
the driver of obstacles near the bumper.
When the “Interrupt Display” is turned on
in the Sonar settings, the sonar indicator
will also appear in the center display. (See
“Sonar indicator” (P.5-134).) The system
detects front obstacles when the shift
lever is in the D (Drive) position or N
(Neutral) position. The system detects
both front and rear obstacles when the
shift lever is in the R (Reverse) position.
The system may not detect objects at
speeds above 6 MPH (10 km/h) and may
not detect certain angular or moving
objects.
The sonar system detects obstacles up to
3.9 ft (1.2 m) from the bumper with a
decreased coverage area at the outer
corners of the bumper. Refer to the
illustration for approximate zone cover-
age areas. As you move closer to the obstacle, the rate of the tone increases.
When the obstacle is less than 11.8 in (30
cm) away, the tone will sound continu-
ously.
Keep the corner/center sensors (located
on the bumper fascia) free from snow, ice
and large accumulations of dirt (do not
clean the sensors with sharp objects). If
the sensors are covered, it will affect the
accuracy of the sonar system.
The sensitivity level of the corner/center
sensors can be adjusted (higher or lower)
in the Sonar settings on the center dis-
play. (See “Sonar settings” (P.5-133).)
The intermittent tone will stop in 3
seconds when an obstacle is detected
by only the corner sensor and the dis-
tance does not change.

SONAR INDICATOR
With the “Interrupt Display” turned on in
the Sonar settings, when the corner/
center sensors detect obstacles near the
bumper, a tone will sound and the sonar
indicator will appear in the center display
. When the RearView Monitor is dis-
played, the sonar indicator will appear in
the upper corner of the display
.
The sonar indicators
andindicate the
position of the object and the distance to
the object with its color and rate of
blinking.
When an object is detected, the indicator
(green) appears and blinks (the tone
sounds intermittently). When the vehicle
moves closer to the object, the color of
the indicator turns yellow and the rate of
blinking increases (the rate of the tone
increases). When the bumper is very close
to the object, less than 11.8 in (30 cm)
away, the indicator stops blinking and
turns red (the tone sounds continuously).
When the RearView Monitor is dis-
played, the colors of the sonar indicator
and the distance guide lines in the rear
view indicate different distances to the
object.
When the
is touched, the sonar will
be turned off temporarily.
The sonar indicator can be turned off in

the Sonar settings on the center display.
(See “Sonar settings” (P.5-133).) When the
sonar indicator is off, only a tone sounds
when the sonar detect obstacles.
WARNING
If the engine is not running or is
turned off while driving, the power
assist for the steering will not work.
Steering will be harder to operate.
The power assisted steering uses a hy-
draulic pump, driven by the engine, to
assist steering.
If the engine stops or the drive belt
breaks, you will still have control of the
vehicle. However, much greater steering
effort is needed, especially in sharp turns
and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate
hydraulic circuits. If one circuit malfunc-
tions, you will still have braking ability at
two wheels.
You may feel a small click and hear a
sound when the brake pedal is fully
depressed slowly. This is not a malfunc-
tion and indicates that the brake assist
mechanism is operating properly.
Hydraulically-assisted brakes
The hydraulically-assisted brake system is
designed to use a hydraulic pump driven
electrically, to assist braking. If the engine
stops, you can stop the vehicle by de-
pressing the foot brake pedal. However,
greater foot pressure on the foot brake
pedal will be required to stop the vehicle.
The stopping distance will be longer.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet.
As a result, your braking distance will be
longer and the vehicle may pull to one
side during braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake
pedal to heat-up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakes

function correctly.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes when-
ever the stopping effect of the parking
brake is weakened or whenever the
parking brake shoes and/or drums/ro-
tors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle
service manual. It is recommended you
visit a NISSAN dealer for this service.
Using the brakes
Avoid resting your foot on the brake
pedal while driving. This will cause over-
heating of the brakes, wearing out the
brake and pads faster and reduce gas
mileage.
To help save the brakes and to prevent
the brakes from overheating, reduce
speed and downshift to a lower gear
before going down a slope or long grade.
Overheated brakes may reduce braking
performance and could result in loss of
vehicle control.
WARNING
.While driving on a slippery sur-
face, be careful when braking,
accelerating or downshifting. Abrupt braking or accelerating
could cause the wheels to skid
and result in an accident.
. If the engine is not running or is
turned off while driving, the
power assist for the brakes will
not work. Braking will be harder.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking
force than a conventional brake booster
even with light pedal force.
WARNING
The Brake Assist is only an aid to
assist braking operation and is not a
collision warning or avoidance de-
vice. It is the driver’s responsibility to
stay alert, drive safely and be in
control of the vehicle at all times.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System
(ABS) is a sophisticated device,
but it cannot prevent accidents
resulting from careless or dan-
gerous driving techniques. It can
help maintain vehicle control dur-
ing braking on slippery surfaces.
Remember that stopping dis-
tances on slippery surfaces will
be longer than on normal sur-
BRAKE ASSIST

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.
Starting and driving5-137

For four-wheel drive
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.
SPECIAL WINTER EQUIPMENT
It is recommended that the following
items be carried in the vehicle during
winter:
.A scraper and stiff-bristled brush to
remove ice and snow from the win-
dows and wiper blades.
. A sturdy, flat board to be placed under
the jack to give it firm support.
. A shovel to dig the vehicle out of
snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
.Wet ice (32°F, 0°C and freezing
rain), very cold snow or ice can be
slick and very hard to drive on.
The vehicle will have much less
traction or “grip” under these
conditions. Try to avoid driving
on wet ice until the road is salted
or sanded. .
Whatever the condition, drive
with caution. Accelerate and slow
down with care. If accelerating or
downshifting too fast, the drive
wheels will lose even more trac-
tion.
. Allow more stopping distance
under these conditions. Braking
should be started sooner than on
dry pavement.
. Allow greater following distances
on slippery roads.
. Watch for slippery spots (glare
ice). These may appear on an
otherwise clear road in shaded
areas. If a patch of ice is seen
ahead, brake before reaching it.
Try not to brake while on the ice,
and avoid any sudden steering
maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous ex-
haust gases under your vehicle.
Keep snow clear of the exhaust
pipe and from around your vehi-
cle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist in
cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F
(−7°C) or lower.
To use the engine block heater
1. Turn the engine off.
2. Open the hood and unwrap the en-
gine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged exten-
sion cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2 - 4 hours,
depending on outside temperatures,
to properly warm the engine coolant.
Use an appropriate timer to turn the
engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it
away from moving parts.

8. After starting your engine, carefullydisconnect the negative cable and
then the positive cable (
???).
9. Replace the vent caps (if so equipped). Be sure to dispose of the cloth used to
cover the vent holes as it may be
contaminated with corrosive acid.
10. Put the battery cover on. Do not attempt to start the engine by
pushing.CAUTION
.
Automatic transmission models
cannot be push-started or tow-
started. Attempting to do so may
cause transmission damage.
. Three way catalyst equipped
models should not be started by
pushing since the three way cat-
alyst may be damaged.
. Never try to start the vehicle by
towing it; when the engine starts,
the forward surge could cause
the vehicle to collide with the
tow vehicle.
CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle
fire.
. To avoid the danger of being
scalded, never remove the radia-
tor cap or coolant reservoir cap
while the engine is still hot. When
the radiator cap or coolant reser-
voir cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc., take
the following steps:
1. Move the vehicle safely off the road, apply the parking brake and move the
shift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the heater and air condi- tioner. Open all the windows, move
the heater or air conditioner tempera-
ture control to maximum hot and fan
PUSH STARTING IF YOUR VEHICLE OVERHEATS

control to high speed.
3. If engine overheating is caused by climbing a long hill on a hot day, run
the engine at a fast idle (approxi-
mately 1,500 rpm) until the tempera-
ture gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from
the radiator before opening the hood.
(If steam or coolant is escaping, turn
off the engine.) Do not open the hood
further until no steam or coolant can
be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent get-
ting burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling
fan is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking or the cooling fan does
not run, stop the engine.
WARNING
Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or get caught in, engine
belts or the engine cooling fan. The
engine cooling fan can start at any
time.
7. After the engine cools down, check the coolant level in the reservoir tank
with the engine running. Add coolant
to the reservoir tank if necessary. Have
your vehicle repaired. It is recom-
mended you visit a NISSAN dealer for
this service.
