Door open warning light (ifso equipped)
This light comes on when any of the doors
are not closed securely while the ignition
switch is in the ON position.
Engine oil pressurewarning light
This light warns of low engine oil pressure. If
the light flickers or comes on during nor-
mal driving, pull off the road in a safe area,
stop the engine immediatelyand call a
NISSAN dealer or other authorized repair
shop.
The engine oil pressure warning light is
not designed to indicate a low oil level.
Use the dipstick to check the oil level. For
additional information, refer to “Engine oil”
in the “Do-it-yourself ” section of this
manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by the NISSAN New Vehicle Limited
Warranty. Turn off the engine as soon as
it is safe to do so.
High temperature warning
light (red) (if so equipped)
When the ignition switch is placed in the ON
position, the high temperature warning
light illuminates and then turns off. This in-
dicates that the high temperature sensor
in the engine coolant system is opera-
tional.
When driving, the high temperature warn-
ing light may turn off. This indicates that the
engine coolant temperature is within the
normal range.
CAUTION
If the high temperature warning light
illuminates while the engine is running,
it may indicate the engine temperature
is extremely high. Stop the vehicle
safely as soon as possible. If the vehicle
is overheated, continuing vehicle op-
eration may seriously damage the en-
gine. For additional information, refer
to “If your vehicle overheats” in the “In
case of emergency ” section of this
manual.
Low fuel warning light (if soequipped)
This light comes on when the fuel level in
the fuel tank is getting low. Refuel as soon
as it is convenient, preferably before the
fuel gauge reaches 0 (Empty). There will be
a small reserve of fuel in the tank when
the fuel gauge reaches 0 (Empty).
Low tire pressure warning
light
Your vehicle is equipped with a Tire Pres-
sure Monitoring System (TPMS) that moni-
tors the tire pressure of all tires except the
spare.

the front console power outlet con-
tinues to deliver power until the ac-
cessory power timer has elapsed.
CAUTION
∙ The outlet and plug may be hot during or immediately af ter use.
∙ Only certain power outlets are de- signed for use with a cigarette lighter
unit. Do not use any other power out-
let for an accessory lighter. It is rec-
ommended that you visit a NISSAN
dealer for additional information.
∙ Do not use with accessories that ex- ceed a 12 volt, 120W (10A) power draw.
∙ Do not use double adapters or more than one electrical accessory. ∙ Use power outlets with the engine
running to avoid discharging the ve-
hicle battery.

Dehumidified defogging
This mode is used to defog the windows
and dehumidif y the air.1. Turn the air flow control dial to the
position.
2. Turn the
fan control dial to the
desired position.
3. Press the
button. The indicator
light comes on.
When the
,or positions in be-
tween are selected, the air conditioner au-
tomatically turns on. The air conditioning
system will continue to operate until the
fan control dial is turned to OFF or the ve-
hicle is shut off, even if the air flow control
dial is turned to a position other than
the
position. This dehumidifies the
air which helps defog the windshield.
The
mode automatically turns off, al-
lowing outside air to be drawn into the pas-
senger compartment to further improve
the defogging performance.
4. Turn the temperature control dial to the desired position.
Operating tips
∙ Keep the windows closed while the airconditioner is in operation.
∙ Af ter parking in the sun, drive for two or three minutes with the windows open
to vent hot air from the passenger
compartment. Then, close the win-
dows. This allows the air conditioner to
cool the interior more quickly.
∙ The air conditioning system should
be operated for approximately ten
minutes at least once a month. This
helps prevent 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 high temperature warning
light
illuminates in red indicating
engine coolant temperature is over
the normal range, turn the air condi-
tioner off. For additional information,
refer to “If your vehicle overheats” in
the “In case of emergency ” section of
this manual.
AIR FLOW CHARTS

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol 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 sys-tem are very hot. Keep people, ani-
mals 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. Depositsfrom 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
driving if the engine misfires, or if no-
ticeable loss of performance or other
unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended that 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, damag-
ing 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
inflated to the inflation pressure recom-
mended 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 your tires as soon as pos-
sible, and inflate them to the proper pres-
sure. 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 substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation 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 malfunction indicator is com-
bined with the low tire pressure telltale.
Starting and driving5-3

∙ HEADED UPHILL OR DOWNHILL, NOCURB
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. Place the ignition switch in the LOCK position and remove the key.WARNING
∙ If the engine is not running or isturned off while driving, the power as-
sist for the steering will not work.
Steering will be harder to operate.
∙ When the power steering warning light illuminates with the engine run-
ning, 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. It is recom-
mended that you visit a NISSAN dealer
for this service.
The power steering system is designed to
provide power assist while driving to oper-
ate the steering wheel with light force.
When the steering wheel is operated re-
peatedly or continuously while parking or
driving at a very low speed, the power as-
sist for the steering wheel will be reduced.
This is to prevent overheating of the power
steering system and protect it from getting
damaged. While the power assist is re-
duced, steering wheel operation will be-
come heavy. When the temperature of the
power steering system goes down, the
power assist level will return to normal.
Avoid repeating such steering wheel op- erations that could cause the power steer-
ing system to overheat.
You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the 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 servic-
ing. Have the power steering system
checked. It is recommended that you visit a
NISSAN dealer for this service.
When the power steering warning light illu-
minates 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
steering warning light” in the “Instruments
and controls” section of this manual.
POWER STEERING
Starting and driving5-53

The brake system has two separate hy-
draulic 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 pres-
sure on the brake pedal will be required to
stop the vehicle and stopping distance 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 downshif t 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, becareful when braking, accelerating or
downshif ting. Abrupt braking or ac-
celerating 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 as-
sist for the brakes will not work. Brak-
ing 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 lon-
ger 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 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 perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
∙ The ABS is a sophisticated device, but
it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances 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 af- fect braking effectiveness.

CAUTION
∙ Do not push start this vehicle. Thethree-way catalyst may be damaged.
∙ Continuously Variable Transmission (CVT) models cannot be push-started
or tow-started. Attempting to do so
may cause transmission damage. If your vehicle is overheating (indicated by a
red high temperature warning light),
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 en-
gine 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 radia-
tor 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, ap- ply the parking brake and move the
shif t lever to P (Park).
Do not stop the engine.
2. Turn off the air conditioner.. Open all the windows, move the heater or air condi-
tioner temperature control to maxi-
mum hot and fan control to high
speed. 3. Get out of the vehicle. Look and listen
for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off
the engine.) Do not open the hood fur-
ther until no steam or coolant can be
seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling
fan is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking, the water pump belt is
missing or loose, or the cooling fan
does not run, stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or
the engine cooling fan. The engine cool-
ing fan can start at any time.
PUSH STARTING IF YOUR VEHICLE OVERHEATS
In case of emergency6-11

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. Addi-
tional engine cooling system additives are
not necessary.
WARNING
∙ Never remove the radiator or coolantreservoir 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 informa-
tion 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 addi-tives such as radiator sealer. Additives
may clog the cooling system and
cause damage to the engine, trans-
mission 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 protec-
tion to -34° F (-37° C). If additional
freeze protection is needed due to
weather where you operate your ve-
hicle, add Genuine NISSAN Long Life
Antifreeze/Coolant (blue) concen-
trate following the directions on the
container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s in-
structions to maintain minimum anti-
freeze protection to -34° F (-37° C). The
use of other types of coolant solu-
tions 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
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue),
including 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. For additional information, refer
to the “Maintenance and schedules”
section of this manual.
