Shoulder belt arm (for Coupe
models)
Before fastening the seat belt, pull the
shoulder belt arm forward until it clicks at
the detent position.
Pulling the arm forward will allow an easy
access to the belt.
SEAT BELT EXTENDERS
If, because of body size or driving position,
it is not possible to properly fit the lap-
shoulder belt and fasten it, an extender
that is compatible with the installed seat
belts is available that can be purchased.
The extender adds approximately 8 in
(200 mm) of length and may be used foreither the driver or front passenger seat-
ing position. It is recommended you visit a
NISSAN dealer for assistance with pur-
chasing an extender if an extender is
required.
WARNING
.
It is recommended that only
NISSAN seat belt extenders, made
by the same company which
made the original equipment seat
belts, be used with the NISSAN
seat belts.
. Adults and children who can use
the standard seat belt should not
use an extender. Such unneces-
sary use could result in serious
personal injury in the event of an
accident.
. Never use seat belt extenders to
install child restraints. If the child
restraint is not secured properly,
the child could be seriously in-
jured or killed in a collision or a
sudden stop.
SEAT BELT MAINTENANCE
.To clean the seat belt webbings,
apply a mild soap solution or any
solution recommended for cleaning
upholstery or carpets. Then, wipe with
a cloth and allow the seat belts to dry
in the shade. Do not allow the seat
belts to retract until they are comple-
tely dry.
. If dirt builds up in the shoulder belt
guide of the seat belt anchors, the
seat belts may retract slowly. Wipe the
shoulder belt guide with a clean, dry
cloth.
. Periodically check to see that the
seat belt and the metal components
such as buckles, tongues, retractors,
flexible wires and anchors work prop-
erly. If loose parts, deterioration, cuts
or other damage on the webbing is
found, the entire seat belt assembly
should be replaced.

2-14Instruments and controls
If you have a flat tire, replace it
with a spare tire (if so equipped)
or repair it with the tire puncture
repair kit (if so equipped) as soon
as possible. If no tire is flat and all
tires are properly inflated, it is
recommended you consult a
NISSAN dealer.
. 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 the 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.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
CAUTION
.The TPMS is not a substitute for
the regular tire pressure check. Be sure to check the tire pressure
regularly.
. If the vehicle is being driven at
speeds of less than 16 MPH (25
km/h), the TPMS may not operate
correctly.
. Be sure to install the specified
size of tires to the four wheels
correctly.
Master warning light
When the ignition switch is in the ON
position, the master warning light illumi-
nates if any of the following are displayed
on the vehicle information display:
.No key warning
. Low fuel warning
. Low washer fluid warning
. Parking brake release warning
. Door/rear hatch/trunk open warning
. Loose fuel cap warning
. Check tire pressure warning

Seat belt warning light and
chime
The light and chime remind you to fasten
seat belts. The light illuminates whenever
the ignition switch is pushed to the ON
position, and will remain illuminated until
the driver’s seat belt is fastened. At the
same time, the chime will sound for about
6 seconds unless the driver’s seat belt is
securely fastened.
The seat belt warning light for the front
passenger will illuminate if the seat belt is
not fastened when the front passenger’s
seat is occupied. For approximately 5
seconds after the ignition switch is in
the ON position, the system does not
activate the warning light for the front
passenger.
See “Seat belts” (P.1-10) for precautions on
seat belt usage.
Supplemental air bag warning
light
After pushing the ignition switch to the
ON position, the supplemental air bag
warning light will illuminate. The air bag
warning light will turn off after about 7
seconds if the front air bag, side air bag
and curtain air bag systems and/or pre-
tensioner system are operational.

sult in serious injury or death.
.The RearView Monitor is a conve-
nience but it is not a substitute
for proper backing. Always turn
and look out the windows, and
check mirrors to be sure that it is
safe to move before operating
the vehicle. Always back up
slowly.
. The system is designed as an aid
to the driver in showing large
stationary objects directly behind
the vehicle, to help avoid dama-
ging the vehicle.
. The distance guide line and the
vehicle width line should be used
as a reference only when the
vehicle is on a level paved sur-
face. The distance viewed on the
monitor is for reference only and
may be different than the actual
distance between the vehicle and
displayed objects.

Indicate the predictive course when back-
ing up. The predictive course lines will be
displayed on the monitor when the shift
lever is in the “R” (Reverse) position and
the steering wheel is turned. The predic-
tive course lines will move depending on
how much the steering wheel is turned
and will not be displayed while the steer-
ing wheel is in the neutral position.
The vehicle width guide lines and the
width of the predictive course lines are
wider than the actual width and course.
HOW TO PARK WITH PREDICTIVE

WARNING
. If the tires are replaced with
different sized tires, the predic-
tive course line may not be dis-
played correctly.
. On a snow-covered or slippery
road, there may be a difference
between the predictive course
line and the actual course line.
. The displayed lines will appear
slightly off to the right because
the rearview camera is not in-
stalled in the rear center of the vehicle.

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-

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.

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.8-33) of this manual.
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-

Installing the spare tire
The T-type spare tire is designed for
emergency use. (See specific instruc-
tions under the heading “Wheels and
tires” (P.8-26).)
1. Clean any mud or dirt from the sur-face between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
Check that all the wheel nuts contact
the wheel surface horizontally.
Models equipped with different
sized tires in the front and rear:

Checking the tire pressure
1. Remove the valve stem cap fromthe tire.
2. Press the pressure gauge squarely onto the valve stem.
Do not press too hard or force
the valve stem sideways, or air
will escape. If the hissing sound
of air escaping from the tire is
heard while checking the pres-
sure, reposition the gauge to
eliminate this leakage. 3. Remove the gauge.
4. Read the tire pressure on the
gauge stem and compare it to
the specification shown on the
Tire and Loading Information
label.
5. Add air to the tire as needed. If too much air is added, press the
core of the valve stem briefly
with the tip of the gauge stem to
release pressure. Recheck the
pressure and add or release air
as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, including the spare.
