Parking brake reminder chime
A chime will sound if the vehicle speed is above
4 MPH (7 km/h) with the parking brake applied.
Stop the vehicle and release the parking brake.
Brake pad wear warning
The disc brake pads have audible wear warn-
ings. When a brake pad requires replacement, it
will make a high pitched scraping sound when
the vehicle is in motion. This scraping sound will
first occur only when the brake pedal is
depressed. After more wear of the brake pad
the sound will always be heard even if the brake
pedal is not depressed. Have the brakes
checked as soon as possible if the warning
sound is heard.

5-6Starting and driving
For Canada:
This device complies with RSS-210 of
Industry Canada. Operation is subject to
the following two conditions: (1) this
device may not cause interference, and
(2) this device must accept any interfer-
ence, including interference that may
cause undesired operation of the device.
AVOIDING COLLISION AND ROLL-
OVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times. Obey
all traffic regulations. Avoid excessive speed,
high speed cornering, or sudden steering
maneuvers, because these driving practices
could cause you to lose control of your vehicle.
As with any vehicle, a loss of control could
result in a collision with other vehicles or
objects, or cause the vehicle to rollover,
particularly if the loss of control causes the
vehicle to slide sideways. Be attentive at all
times, and avoid driving when tired. Never drive
when under the influence of alcohol or drugs (including prescription or over-the-counter
drugs which may cause drowsiness) . Always
wear your seat belt as outlined in the “Seat
belts” (P.1-9) of this manual, and also instruct
your passengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers.
In a rollover crash, an
unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a
seat belt.
OFF-ROAD RECOVERY
While driving, the right side or left side wheels
may unintentionally leave the road surface. If this
occurs, maintain control of the vehicle by
following the procedure below. Please note that
this procedure is only a general guide. The
vehicle must be driven as appropriate based on
the conditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course.
4. When appropriate, slowly release the accel- erator pedal to gradually slow the vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the vehicle speed is reduced. Do not attempt to drive
the vehicle back onto the road surface until
vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return to the
road surface. When all tires are on the road
surface, steer the vehicle to stay in the
appropriate driving lane.
.If you decide that it is not safe to returnthe vehicle to the road surface based on
vehicle, road or traffic conditions, gradu-
ally slow the vehicle to a stop in a safe
place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged due
to hitting a curb or pothole. Rapid air pressure
loss can also be caused by driving on under-
inflated tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially at highway
speeds.
Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspect the tires for wear and damage. See
“Wheels and tires” (P.8-30) of this manual.
If a tire rapidly loses air pressure or “blows-out”
while driving maintain control of the vehicle by

following the procedure below. Please note that
this procedure is only a general guide. The
vehicle must be driven as appropriate based on
the conditions of the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air
pressure. Losing control of the vehicle
may cause a collision and result in
personal injury.
.The vehicle generally moves or pulls
in the direction of the flat tire.
. Do not rapidly apply the brakes.
. Do not rapidly release the accelera-
tor pedal.
. Do not rapidly turn the steering
wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course.
3. When appropriate, slowly release the accel- erator pedal to gradually slow the vehicle. 4. Gradually steer the vehicle to a safe location
off the road and away from traffic if possible.
5. Lightly apply the brake pedal to gradually stop the vehicle.
6. Turn on the hazard warning flashers and either contact a roadside emergency service
to change the tire or see “Changing a flat
tire (for models with spare tire)” (P.6-4) of
this Owner’s Manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of
alcohol or drugs. Alcohol in the blood-
stream reduces coordination, delays
reaction time and impairs judgement.
Driving after drinking alcohol increases
the likelihood of being involved in an
accident injuring yourself and others.
Additionally, if you are injured in an
accident, alcohol can increase the se-
verity of the injury.
NISSAN is committed to safe driving. However,
you must choose not to drive under the influence
of alcohol. Every year thousands of people are injured or killed in alcohol-related accidents.
Although the local laws vary on what is
considered to be legally intoxicated, the fact is
that alcohol affects all people differently and
most people underestimate the effects of
alcohol.
Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter,
prescription, and illegal drugs) . Don’t drive if
your ability to operate your vehicle is impaired by
alcohol, drugs, or some other physical condition.
Starting and driving5-7

5-26Starting and driving
4. Push the ignition switch to the OFF position.
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 hydraulic
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, espe-
cially in sharp turns and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and 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.
POWER STEERING BRAKE SYSTEM

PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drums/rotors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle
service manual and can be performed by a
NISSAN dealer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating 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 surface,
be careful when braking, accelerat-
ing 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 device. 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 dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal
Starting and driving5-27
BRAKE ASSIST

5-28Starting and driving
surfaces 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 Information
label. See “Tire and Loading
Information label” (P.9-13) of
this manual.
— For detailed information, see “Wheels and tires” (P.8-30) of
this manual.
The Anti-lock Braking System (ABS) controls
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
preventing 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 dis-
tances.
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 notindicate a malfunction. If the computer senses
a malfunction, it switches the ABS off and
illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates 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 above 3 to 6 MPH
(5 to 10 km/h).
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. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.

8-4Maintenance and do-it-yourself
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*:When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires cannot be rotated, as the
front tires are a different size from the rear tires
and the direction of wheel rotation is fixed in
each tire.
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If
necessary, adjust the pressure in all tires,
including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Tire, wheel alignment and balance: If the
vehicle should pull to either side while driving on
a straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be needed.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
NISSAN Warranty Information Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism: On a fairly steep hill, check that your
vehicle is held securely with the shift lever in the
P (Park) position without applying any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels spongy or the vehicle seems to take longer to
stop, see a NISSAN dealer immediately. Keep
the floor mat away from the pedal.
Brakes:
Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only the
parking brake applied. If the parking brake needs
adjusted, see a NISSAN dealer.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, adjuster
and retractors) operate properly and smoothly,
and are installed securely. Check the belt
webbing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.
Steering wheel: Check for changes in the
steering conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.

SDI2362
Be careful not to clog the washer nozzle*A.
This may cause improper windshield washer
operation. If the nozzle is clogged, remove any
objects with a needle or small pin
*B.Be
careful not to damage the nozzle. If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
WARNING
See a NISSAN dealer for a brake
system check if the brake pedal height
does not return to normal.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear warn-
ings. When a brake pad requires replacement, it
will make a high pitched scraping sound when
the vehicle is in motion. This scraping sound will
first occur only when the brake pedal is
depressed. After more wear of the brake pad
the sound will always be heard even if the brake
pedal is not depressed. Have the brakes
checked as soon as possible if the wear warning
sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other noise
may be heard. Occasional brake noise duringlight to moderate stops is normal and does not
affect the function or performance of the brake
system.
Proper brake inspection intervals should
be followed.
For additional information, see the
maintenance log section of your “NISSAN
Service and Maintenance Guide”.
