FUEL-FILLER CAP
WARNING
.Gasoline is extremely flammable
and highly explosive under cer-
tain conditions. You could be
burned or seriously injured if it is
misused or mishandled. Always
stop engine and do not smoke or
allow open flames or sparks near
the vehicle when refueling.
. Do not attempt to top off the fuel
tank after the fuel pump nozzle
shuts off automatically. Contin-
ued refueling may cause fuel
overflow, resulting in fuel spray
and possibly a fire.
. Use only an original equipment
type fuel-filler cap as a replace-
ment. It has a built-in safety valve
needed for proper operation of
the fuel system and emission
control system. An incorrect cap
can result in a serious malfunc-
tion and possible injury. It could
also cause the malfunction indi-
cator light to come on. .
Never pour fuel into the throttle
body to attempt to start your
vehicle.
. Do not fill a portable fuel contain-
er in the vehicle or trailer. Static
electricity can cause an explosion
of flammable liquid, vapor or gas
in any vehicle or trailer. To reduce
the risk of serious injury or death
when filling portable fuel contain-
ers:
— Always place the container on
the ground when filling.
— Do not use electronic devices when filling.
— Keep the pump nozzle in con- tact with the container while
you are filling it.
— Use only approved portable fuel containers for flammable
liquid.
CAUTION
. If fuel is spilled on the vehicle
body, flush it away with water to
avoid paint damage. .
Insert the cap straight into the
fuel-filler tube, then tighten until
the fuel-filler cap clicks. Failure to
tighten the fuel-filler cap properly
may cause the
malfunction
indicator light (MIL) to illuminate.
If the
light illuminates be-
cause the fuel-filler cap is loose
or missing, tighten or install the
cap and continue to drive the
vehicle. The
light should turn
off after a few driving trips. If the
light does not turn off after a
few driving trips, have the vehicle
inspected. It is recommended you
visit a NISSAN dealer for this
service.
. The LOOSE FUEL CAP warning will
appear if the fuel-filler cap is not
properly tightened. It may take a
few driving trips for the message
to be displayed. Failure to tighten
the fuel-filler cap properly after
the LOOSE FUEL CAP warning
appears may cause the
Mal-
function Indicator Light (MIL) to
illuminate.
Pre-driving checks and adjustments3-35

THREE-WAY CATALYST
The three-way catalyst is an emission
control device installed in the exhaust
system. Exhaust gases in the three-way
catalyst are burned at high temperatures
to help reduce pollutants.
WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system
components.
. 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.
CAUTION
.Do not use leaded gasoline. De-
posits from leaded gasoline ser-
iously reduce the three-way
catalyst’s ability to help reduce
exhaust pollutants.
. Keep your engine tuned up. Mal-
functions in the ignition, fuel in-
jection, or electrical systems can cause overrich fuel flow into the
three-way catalyst, causing it to
overheat. Do not keep driving if
the engine misfires, or if notice-
able loss of performance or other
unusual operating conditions are
detected. Have the vehicle in-
spected. It is recommended you
visit a NISSAN dealer for this
service.
. Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire,
damaging the three-way catalyst.
. Do not race the engine while
warming it up.
. Do not push or tow your vehicle
to start the engine.
TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire infla-
tion pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or tire
inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illumi-
nates a low tire pressure telltale when
one or more of your tires is significantly
under-inflated. Accordingly, when the low
tire pressure telltale illuminates, you
should stop and check your tires as soon
as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect
the vehicle’s handling and stopping abil-
ity.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating prop-
erly. The TPMS malfunction indicator is
combined with the low tire pressure tell-
tale. When the system detects a malfunc-
tion, the telltale will flash for
approximately one minute and then re-

.Make sure the area around the vehicle
is clear.
. Check fluid levels such as engine oil,
coolant, brake fluid and window
washer fluid as frequently as possible,
or at least whenever you refuel.
. Check that all windows and lights are
clean.
. Visually inspect tires for their appear-
ance and condition. Also check tires
for proper inflation.
. Lock all doors.
. Position seat and adjust head re-
straints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen-
gers to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to
the ON position. (See “Warning lights,
indicator lights and audible remin-
ders” (P.2-10).) 1. Apply the parking brake.

Upshift indicator:
The up-shift indicator is located in the
tachometer and shows the driver the
timing to shift into a higher gear by
illuminating. The use of the up-shift
indicator will help you to upshift at a
constant engine speed from any gear.
The up-shift indicator will start flashing
when the engine speed reaches about
500 rpm before the set figure while
driving, and then illuminate after the
engine speed reaches the set figure.
The engine speed for upshifting can be
set on the vehicle information display. See
“Trip computer” (P.2-25).
There may be a slight difference be-tween the timing of the up-shift indica-
tor illumination and the tachometer
indication.
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, depending on the vehicle
speed.
Fail-safe
When 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
spinning 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 condi-
tion. If it does not return to its normal
operating condition, have the transmis-
sion checked and repaired, if necessary.
It is recommended you visit a NISSAN
dealer for this service.

warning:
The SynchroRev Match mode (S-MODE)
warning will appear on the vehicle infor-
mation display and the S-MODE indicator
will turn off if a system malfunction
occurs.
If the warning appears, the S-MODE func-
tion will not operate, but manual trans-
mission will operate normally and driving
can be continued. Have the system
checked. It is recommended you visit a
NISSAN dealer for this service.

Activating the system:
To activate the S-MODE, push the S-
MODE switch
. The S-MODE indicatoron the tachometer will show “S”. To
deactivate, push and hold the S-MODE
switch for more than 1 second. The S-
MODE indicator will turn off.While the S-MODE is off, you can drive the
vehicle as a conventional manual trans-
mission model.
Note that the status of the S-MODE (on or
off) is memorized even after the ignition
switch is turned off; however, it will be
initialized (off) when the battery is dis-
connected.
The transmission position indicator
shows the selected gear: N (Neutral), 1, 2,
3, 4, 5, 6, R (Reverse).
SynchroRev Match mode (S-MODE) op-
eration:
The SynchroRev Match mode (S-MODE)
automatically adjusts the engine speed
by controlling the engine throttle. The
accelerator pedal does not have to be
depressed.
The system detects the clutch pedal and
shift lever operations, and then calculates
the target engine speed using the shifting
gear position and the vehicle speed
information.
The system provides accurate engine
speed control that helps achieve quick
gear shifting and reduces shift shock on
clutch engagement.

PRECAUTIONS ON CRUISE CON-
TROL
.If the cruise control system malfunc-
tions, it will cancel automatically. The
CRUISE indicator light on the meter
panel will then blink to warn the driver.
. If the engine coolant temperature
becomes excessively high, the cruise
control system will cancel automati-
cally.
. If the CRUISE indicator light blinks,
turn the cruise control main switch
off and have the system checked. It is
recommended you visit a NISSAN
dealer for this service.
. The CRUISE indicator light may blink
when the cruise control main switch is
turned ON while pushing the ACCEL/
RES, COAST/SET or CANCEL switch. To
properly set the cruise control system,
perform the following procedures.
WARNING
Do not use the cruise control when
driving under the following condi-
tions:
.when it is not possible to keep the
vehicle at a set speed .
in heavy traffic or in traffic that
varies in speed
. on winding or hilly roads
. on slippery roads (rain, snow, ice,
etc.)
. in very windy areas
Doing so could cause a loss of
vehicle control and result in an acci-
dent.
CAUTION
On manual transmission models, do
not shift into N (Neutral) without
depressing the clutch pedal when
the cruise control is set. Should this
occur, depress the clutch pedal and
turn the main switch off immedi-
ately. Failure to do so may cause
engine damage.
CRUISE CONTROL

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-
14) of this manual.
— For detailed information, see “Wheels and tires” (P.8-26) of
this manual.
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).
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.
