Accelerator downshift
— In D (Drive) position —For passing or hill climbing, fully depress the
accelerator pedal to the floor. This shifts the
transmission down into the lower gear, depend-
ing on the vehicle speed.Fail-safeWhen the fail-safe operation occurs, note that
the transmission will be locked in any of the
forward gears according to the condition.
If the vehicle is driven under extreme
conditions, such as excessive wheel spin-
ning and subsequent hard braking, the
fail-safe system may be activated. This will
occur even if all electrical circuits are
functioning properly. In this case, push
the ignition switch to the OFF position and
wait for 3 seconds. Then push the ignition
switch back to the ON position. The vehicle
should return to its normal operating
condition. If it does not return to its normal
operating condition, have a NISSAN dealer
check the transmission and repair if ne-
cessary.

.Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
. Drive at moderate speeds on the highway.
. Avoid unnecessary stopping and braking.
Keep a safe distance behind other vehicles.
. Select a gear range suitable to road condi-
tions.
. Avoid unnecessary prolonged engine idling.
. Keep your engine tuned up.
. Follow the recommended periodic mainte-
nance schedule.
. Keep the tires inflated at the correct
pressure. Improper tire pressure will in-
crease wear and waste fuel.
. Make sure the front wheels are properly
aligned. Improper alignment will cause pre-
mature tire wear and lower fuel economy.
. Air conditioner operation lowers fuel econ-
omy. Use the air conditioner only when
necessary.
. When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.

WARNING
.Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
. Never leave the engine running
while the vehicle is unattended.
. Do not leave children unattended
inside the vehicle. They could un-
knowingly activate switches or con-
trols. Unattended children could
become involved in serious acci- dents.
. Safe parking procedures require
that both the parking brake be
applied and the transmission placed
into P (Park) for Automatic Trans-
mission (AT) model or in an appro-
priate gear for Manual Transmission
(MT) model. Failure to do so could
cause the vehicle to move unexpect-
edly or roll away and result in an
accident.

Place the shift lever in the R (Reverse) gear.
When parking on an uphill grade, place the
shift lever in the 1st gear.
3. To help prevent the vehicle from rolling into the street when parked on a sloping drive
way, it is a good practice to turn the wheels
as illustrated.
.HEADED DOWNHILL WITH CURB:
*1
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
.HEADED UPHILL WITH CURB:
*2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
.HEADED UPHILL OR DOWNHILL, NO
CURB:
*3
Turn the wheels toward the side of the road
so the vehicle will move away from the
center of the road if it moves.
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.POWER STEERING

BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.Vacuum assisted brakesThe 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.
When the brake pedal is depressed slowly and
firmly, you may hear a clicking noise and feel a
slight pulsation. This is normal and indicates that
the Brake Assist System is operating.Wet brakesWhen 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-INBreak 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 brakesAvoid 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
wheelstoskidandresultinan
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 SYSTEM

Black plate (300,1)
Model "Z34-D" EDITED: 2009/ 9/ 10
BRAKE ASSISTWhen 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
surfaces even with ABS. Stopping distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire chains.
Alwaysmaintainasafedistance
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” in the “9.
Technical and consumer infor-
mation” section of this manual.
— For detailed information, see “WHEELS AND TIRES” in the
“8. Maintenance and do-it-your-
self” section 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 systemDepress 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 featureThe 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 malfunction, it switches the ABS off and
illuminates the ABS warning light on the
BRAKE ASSIST5-26
Starting and driving

Black plate (301,1)
Model "Z34-D" EDITED: 2009/ 9/ 10
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 operationThe 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.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving con-
ditions, the VDC system helps to perform the
following functions.
.
Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
. Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
. Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following
conditions:
— understeer (vehicle tends to not follow the steered path despite increased steering
input)
— oversteer (vehicle tends to spin due to certain road or driving conditions) .
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.
When the VDC system operates, the
indicator in the instrument panel flashes so note
the following:
. The road may be slippery or the system may determine some action is required to help
keep the vehicle on the steered path.
. You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
. Adjust your speed and driving to the road
conditions.
See “Slip indicator light” in the “2. Instruments
and controls” section and “Vehicle Dynamic
Control (VDC) off indicator light” in the “2.
Instruments and controls” section.
If a malfunction occurs in the system, the
and
indicatorlightscomeoninthe
instrument panel. The VDC system automatically
turns off when these indicator lights are on.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator illuminates to
indicate the VDC system is off. When the VDC
switch is used to turn off the system, the VDC
system still operates to prevent one drive wheel
from slipping by transferring power to a non
slipping drive wheel. The
indicator flashes
if this occurs. All other VDC functions are off and
the
indicator will not flash. The VDC
System is automatically reset to on when the
ignition switch is placed in the off position then
back to the on position.

that tests the system each time you start the
engine and move the vehicle forward or in
reverse at a slow speed. When the self-test
occurs, you may hear a “clunk” noise and/or feel
a pulsation in the brake pedal. This is normal and
is not an indication of a malfunction.
WARNING
.The VDC system is designed to help
the driver maintain stability but
does not prevent accidents due to
abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful
when driving and cornering on slip-
pery surfaces and always drive care-
fully.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs,
stabilizer bars, bushings and
wheels are not NISSAN recom-
mended for your vehicle or are
extremely deteriorated the VDC sys-
tem may not operate properly. This
could adversely affect vehicle hand-
ling performance, and the
in-
dicator may flash or bothand
indicator lights may illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extre-
mely deteriorated, the VDC system
may not operate properly and bothand
indicator lights may
illuminate.
. If engine control related parts are
not NISSAN recommended or are
extremely deteriorated, both the
and
indicator lights may
illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the
in-
dicator may flash or bothand
indicator lights may illuminate.
Do not drive on these types of
roads.
. When driving on an unstable sur-
face such as a turntable, ferry,
elevator or ramp, the
indicator
may flash or bothand
indicator lights may illuminate. This
is not a malfunction. Restart the
engine after driving onto a stable surface.
. If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not
operate properly and the
in-
dicator may flash or bothand
indicator lights may illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.

FREEING A FROZEN DOOR LOCKTo 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.ANTIFREEZEIn the winter when it is anticipated that the
outside temperature will drop below 328F(0 8C) ,
check antifreeze to assure proper winter protec-
tion. For additional information, see “ENGINE
COOLING SYSTEM” in the “8. Maintenance
and do-it-yourself” section.BATTERYIf 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” in the “8. Maintenance and do-
it-yourself” section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “ENGINE COOLING
SYSTEM” in the “8. Maintenance and do-it-
yourself” section.
TIRE EQUIPMENTSUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. 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.
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” in the “8. Maintenance and do-it-
yourself” section of this manual.SPECIAL WINTER EQUIPMENTIt 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 windows 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 8F, 0 8C 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 down-
shifting too fast, the drive wheels
will lose even more traction.
. Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
. Allow greater following distances
on slippery roads.

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, 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 “WARNING/INDICATOR
LIGHTS AND AUDIBLE REMINDERS” in the
“2. Instruments and controls” section and “TIRE
PRESSURE MONITORING SYSTEM (TPMS)”
in the “5. Starting and driving” section.
WARNING
.If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possi-
ble. Driving 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 serious
personal injury. Check the tire pres-
sure 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.
. 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 approxi-
mately 1 minute. The light will
remain on after 1 minute. Contact
your NISSAN dealer as soon as
possible for tire replacement and/
or system resetting.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction of the tire pressure sensors (for mod-
els not equipped with the emer-
gency tire puncture repair kit) .
. If you used the Emergency Tire
Sealant to repair a minor tire punc-
ture, your NISSAN dealer will also
need to replace the TPMS sensor in
addition to repairing or replacing
the tire (for models equipped with
the emergency tire puncture repair
kit) .
. NISSAN recommends using only
NISSAN Genuine Emergency Tire
Sealant provided with your vehicle.
Other tire sealants may damage the
valve stem seal which can cause the
tire to lose air pressure (for models
equipped with the emergency tire
puncture repair kit) .
CHANGING A FLAT TIRE (for models
with spare tire)If you have a flat tire, follow the instructions
below.Stopping the vehicle1. Safely move the vehicle off the road and
away from traffic.
