CAUTION
If the gauge indicates a coolant tempera-
ture near the hot (H) end of the normal
range, reduce vehicle speed to decrease
the temperature. If the gauge is over the
normal range, stop the vehicle as soon as
safely possible. If the engine is over-
heated, continued operation of the vehicle
may seriously damage the engine. For ad-
ditional information, refer to “If your ve-
hicle overheats” in the “In case of emer-
gency” section for immediate action
required
FUEL GAUGE
NOTE:
The ignition switch must be placed in the
ON position for the gauge to give a reading.
The gauge indicates theapproximatefuel level
in the tank.
The gauge may move slightly during braking,
turning, acceleration, or going up or down hills.
The low fuel warning light comes on when the
amount of fuel in the tank is getting low. Refill the fuel tank before the gauge regis-
ters 0 (Empty) .
The arrow on the fuel pump symbol indi-
cates the fuel-filler location.
CAUTION
● If the vehicle runs out of fuel, theMalfunction Indicator Light (MIL) may
come on. Refuel as soon as possible.
After a few driving trips. the
light
should turn off. If the light remains on
after a few driving trips, have the vehicle
inspected by a NISSAN dealer.
● For additional information, refer to
“Malfunction Indicator Light (MIL)” in
this section.

WARNING
Do not use or allow occupants to use the
seat heater if you or the occupants cannot
monitor elevated seat temperatures or
have an inability to feel pain in body parts
that contact the seat. Use of the seat
heater by such people could result in seri-
ous injury.
CAUTION
●The battery could run down if the seat
heater is operated while the engine is
not running.
● Do not use the seat heater for extended
periods or when no one is using the
seat.
● Do not put anything on the seat which
insulates heat, such as a blanket, cush-
ion or seat cover, etc. Otherwise, the
seat may become overheated.
● Do not place anything hard or heavy on
the seat or pierce it with a pin or similar
object. This may result in damage to the
heater.
● Any liquid spilled on the heated seat
should be removed immediately with a
dry cloth. ●
When cleaning the seat, never use
gasoline, benzine, thinner, or any simi-
lar materials.
● If any malfunctions are found or the
heated seat does not operate, turn the
switch off and have the system checked
by a NISSAN dealer.
The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system on for most driv-
ing conditions.
If the vehicle is stuck in mud or snow, the VDC
system reduces the engine output to reduce
wheel spin. The engine speed will be reduced
even if the accelerator is depressed to the floor. If
maximum engine power is needed to free a stuck
vehicle, turn the VDC system off.
To turn off the VDC system, push the VDC OFF
switch. The
indicator will come on.

Dehumidified defogging
This mode is used to defog the windows and
dehumidify the air.1. Press the
air flow control button.
2. Turn the fan control dial to the desired posi- tion.
● When the
orare selected, the
air conditioner automatically turns on if the
outside temperature is more than 36°F
(2°C) . This dehumidifies the air which helps
defog the windshield. The
mode au-
tomatically turns off, allowing outside air to
be drawn into the passenger compartment
to further improve the defogging perfor-
mance.
● The air conditioner is always on in
mode, regardless of whether the indicator
light is on or off.
3. Turn the temperature control dial to the de- sired position.
Operating tips
●Keep the windows and moonroof closed
while the air conditioner is in operation.
● After parking in the sun, drive for 2 or 3 min-
utes with the windows open to vent hot air
from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior more quickly.
● The air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
● A visible mist may be seen coming from the
ventilators in hot, humid conditions as the air
is cooled rapidly. This does not indicate a
malfunction.
● If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. For additional
information, refer to “If your vehicle
overheats” in the “In case of emer-
gency” section of this manual.
AIR FLOW CHARTS
The following charts show the button and dial
positions for MAXIMUM AND QUICK heating,
cooling or defrosting. The air recirculation
button should always be in the OFF posi-
tion for heating and defrosting.

●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. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
● Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
● 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
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation 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 determine 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 illuminates 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 all four 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 efficiency and tire tread
life, and may affect the vehicle’s handling and
stopping ability. 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 properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

2.Manual transmission models
Place the shift lever in the R (Reverse) posi-
tion. When parking on an uphill grade, place
the shift lever in 1st gear.
Continuously Variable Transmission
(CVT) models
Move the shift lever into the P (Park) position.
3. To help prevent the vehicle from rolling into traffic when parked on an incline, 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 cen-
ter of the road if it moves.
4. Place the ignition switch in the LOCK posi- tion and remove the key.
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.
● When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle, but the steering will be
harder to operate. Have the power
steering system checked by a NISSAN
dealer.
The power steering system is designed to pro-
vide power assist while driving to operate the
steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. When the temperature of the power steer-
ing system goes down, the power assist level will
return to normal. Avoid repeating such steering
wheel operations that could cause the power
steering system to overheat. You may hear a sound when the steering wheel is
operated quickly. However, this is not a malfunc-
tion.
If the electric power steering warning light illumi-
nates while the engine is running, it may indicate
the power steering system is not functioning
properly and may need servicing. Have the power
steering system checked by a NISSAN dealer.
When the electric power steering warning light
illuminates with the engine running, there will be
no power assist for the steering, but you will still
have control of the vehicle. At this time, greater
steering effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information, refer to “Power steer-
ing warning light” in the “Instruments and con-
trols” section of this manual.
POWER STEERING
Starting and driving5-29

The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
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 stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear 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, accelerating or
downshifting. Abrupt braking or accel-
erating 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.
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 the brakes, drive the vehicle at a safe
speed while lightly pressing 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 whenever the
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or drum/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.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●
The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping 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 ve-
hicle 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.

example, strut mounting bolt, engine
lift bracket, etc.) — not to the battery.
● Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal.
6. Start the engine of the booster vehicle and let it run for a few minutes.
7. Keep the engine speed of the booster ve- hicle at about 2,000 rpm and start the en-
gine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, place the ignition
switch in the OFF position and wait 3 to
4 seconds before trying again.
8. After starting the engine, carefully discon- nect the negative cable and then the positive
cable.
CAUTION
●Do not push start this vehicle. The
three-way catalyst may be damaged.
● Continuously Variable Transmission
(CVT) models and Manual Transmission
(MT) cannot be push-started or tow-
started. Attempting to do so may cause
transmission damage
● For manual transmission (MT) models,
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. 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.
WARNING
●
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 radiator cap while the
engine is still hot. When the radiator
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
● Do not open the hood if steam is com-
ing out.
1. Move the vehicle safely off the road, apply the parking brake and move the shift lever to
N (Neutral) (manual transmission) or to P
(Park) (CVT) .
Do not stop the engine.
2. Turn off the air conditioner (if so equipped) . Open all the windows, move the heater or air
conditioner temperature control to maximum
hot and fan control to high speed.
PUSH STARTING IF YOUR VEHICLE OVERHEATS
6-10In case of emergency

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round antifreeze and
coolant protection. The antifreeze solution con-
tains rust and corrosion inhibitors. Additional en-
gine cooling system additives are not necessary.
WARNING
●Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused
by high pressure fluid escaping from
the radiator. For additional information
on precautions, refer to “If your vehicle
overheats” found in the “In case of
emergency” section of this manual.
● The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a Genuine
NISSAN radiator cap.
CAUTION
● Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.
● When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C) . If additional freeze protection
is needed due to weather where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is
used, follow the coolant manufacturer’s
instructions to maintain minimum anti-
freeze protection to -34° F (-37° C) . The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling
system. ●
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km) or
7 years. Mixing any other type of cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) , includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green) , or the use
of non-distilled water will reduce the
life expectancy of the factory-fill cool-
ant. Refer to the NISSAN Service and
Maintenance Guide for more details.
