WARNING
●Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
● Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear
seatback and trunk lid securely latched
when not in use, and prevent children’s
access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
● Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death. ●
If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
● Do not run the engine in closed spaces
such as a garage.
● Do not park the vehicle with the engine
running for any extended length of time.
● Keep the rear vent windows, liftgates,
doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passen-
ger compartment. If you must drive with
one of these open, follow these
precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
● If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the trunk lid or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle. ●
The exhaust system and body should be
inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear 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 sys-
tem 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.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-2Starting and driving

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. 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, 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.

NOTE:
Changes or modification not expressly ap-
proved by the party responsible for compli-
ance could void the user’s authority to op-
erate the equipment.
For Canada:
This device complies with Industry Canada
licence-exempt RSS standard(s) . Opera-
tion is subject to the following two condi-
tions: (1) this device may not cause inter-
ference, and (2) this device must accept any
interference, including interference that
may cause undesired operation of the de-
vice.
TPMS with Easy-Fill Tire Alert
When adding air to an under-inflated tire, the
TPMS with Easy-Fill Tire Alert provides visual and
audible signals outside the vehicle to help you
inflate the tires to the recommended COLD tire
pressure.
Vehicle set-up1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shift lever to the P (Park) position.
3. Place the ignition switch to the ON position. Do not start the engine. Operation
1. Add air to the tire.
2. After a few seconds, the hazard indicators will start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard indica-
tors stop flashing.
4. Perform the above steps for each tire. ●If the tire is over-inflated more than ap-
proximately 4 psi (30 kPa) , the horn
beeps and the hazard indicators flash
three times. To correct the pressure, push
the core of the valve stem on the tire
briefly to release pressure. When the
pressure reaches the designated pres-
sure, the horn beeps once.
● If the hazard indicator does not flash
within approximately 15 seconds after
starting to inflate the tire, it indicates that
the Easy-Fill Tire Alert is not operating.
● The TPMS will not activate the Easy-Fill
Tire Alert under the following conditions:
– If there is interference from an external device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the tire. – There is a malfunction in the TPMS sys-
tem.
– There is a malfunction in the horn or haz- ard indicators.
– The identification code of the tires pres- sure sensor is not registered to the sys-
tem.
– The battery of the tire pressure sensor is low.
● If the Easy-Fill Tire Alert does not operate
due to TPMS interference, move the ve-
hicle about 3 ft (1 m) backward or forward
and try again.
If the Easy-Fill Tire Alert is not working, use a tire
pressure gauge.AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss of
control or an accident.
Be alert and drive defensively at all times. Obey
all traffic regulations. Avoid excessive speed,
high speed cornering, or sudden steering ma-
5-6Starting and driving

●The vehicle generally moves or pulls in
the direction of the flat tire.
● Do not rapidly apply the brakes.
● Do not rapidly release the accelerator
pedal.
● Do not rapidly turn the steering wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course.
3. When appropriate, slowly release the accel- erator pedal to gradually slow the vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from traffic if possible.
5. Lightly apply the brake pedal to gradually stop the vehicle.
6. Turn on the hazard warning flashers and contact a roadside emergency service to
change the tire. For additional information,
refer to “Changing a flat tire” in the “In case
of emergency” section of this manual.DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood
of being involved in an accident injuring
yourself and others. Additionally, if you
are injured in an accident, alcohol can
increase the severity of the injury.
NISSAN is committed to safe driving. However,
you must choose not to drive under the influence
of alcohol. Every year thousands of people are
injured or killed in alcohol-related collisions. Al-
though the local laws vary on what is considered
to be legally intoxicated, the fact is that alcohol
affects all people differently and most people
underestimate the effects of alcohol.
Remember, drinking and driving don’t mix! That is
true for drugs (over-the-counter, prescription)
and illegal drugs, too. Don’t drive if your ability to
operate your vehicle is impaired by alcohol,
drugs, or some other physical condition.
WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The engine will stop when
the ignition switch is pushed three con-
secutive times in quick succession or the
ignition switch is pushed and held for
more than 2 seconds.) If the engine stops
while the vehicle is being driven, this
could lead to a crash and serious injury.
