WARNING
• Make sure the hood is completely
closed and latched before driving.
Failure to do so could cause the hood
to fly open and result in an accident.
• If you see steam or smoke coming
from the engine compartment, to
avoid injury do not open the hood.
FUEL-FILLER CAP
WARNING
• Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seri-
ously injured if it is misused or mis-
handled. Always stop the 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
af ter the fuel pump nozzle shuts off
automatically. Continued refueling
may cause fuel overflow, resulting in
fuel spray and possibly a fire.
• Use only an original equipment type
fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious
malfunction and possible injury. It
could also cause the
Malfunc-
tion Indicator Light (MIL) to come on.
• Never pour fuel into the throttle body
to attempt to start your vehicle.
• Do not fill a portable fuel container 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 containers:
– Always place the container on the
ground when filling.
–
Do not use electronic devices when filling.

HOW TO PARK WITH PREDICTED
COURSE LINES
WARNING
• If the tires are replaced with different
sized tires, the predicted course lines
may be displayed incorrectly.
• On a snow-covered or slippery road,
there may be a difference between
the predicted course line and the ac-
tual course line.
• If the battery is disconnected or be-
comes discharged, the predicted
course lines may be displayed incor-
rectly. If this occurs, please perform
the following procedures:
–
Turn the steering wheel from lock
to lock while the engine is running.
– Drive the vehicle on a straight road
for more than 5 minutes.
• When the steering wheel is turned
with the ignition switch in the ACC
position, the predicted course lines
may be displayed incorrectly. 1. Visually check that the parking space is
safe before parking your vehicle.
2. The rear view of the vehicle is displayed on the screen
OAwhen the shif t lever is
moved to the R (Reverse) position. 3. Slowly back up the vehicle adjusting the
steering wheel so that the predicted

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, 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. Deposits
from leaded gasoline will seriously
reduce the three-way catalyst's abil-
ity 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 warm-
ing 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 all 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 efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Starting and driving5-5

•Always use tires of the same type,
size, brand, construction (bias, bias-
belted, or radial), and tread pattern
on all four wheels. Install tire chains
on the rear wheels when driving on
slippery roads and drive carefully.
• Be sure to check the brakes immedi-
ately af ter driving in mud or water.
For additional information, see “Wet
brakes” (P. 5-118).
• Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
• Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent mainte-
nance may be required. For addi-
tional information, see “Maintenance
under severe operating conditions”
(P. 9-7).
WARNING
Do not operate the push-button igni-
tion switch while driving the vehicle ex-
cept in an emergency. (The engine will
stop when the ignition switch is pushed
three consecutive times in quick suc-
cession 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. When the ignition switch is pushed without
depressing the brake pedal, the ignition
switch position will illuminate as follows:
Push center:
• Once to change to ACC.
• Two times to change to ON.
• Three times to return to OFF.
The ignition switch will automatically re-
turn to the LOCK position when any door is
either opened or closed with the switch in
the OFF position.
When the ignition switch cannot be placed
in the OFF position, proceed as follows:
1. Move the shif t lever to the P (Park)
position.
2. Push the ignition switch. The ignition switch position will change to the ON
position.
3. Push the ignition switch again to the OFF position.
The shif t lever can be moved from the P
(Park) position if the ignition switch is in
the ON position and the brake pedal is
depressed.
If the battery of the vehicle is discharged,
the ignition switch cannot be moved
from the LOCK position.

• Make sure the area around the vehicle isclear.
• Check fluid levels such as engine oil, cool- ant, brake, and windshield-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 appearance and condition. Also check tires for proper
inflation.
• Check that all doors are closed.
• Position seat and adjust head restraints/ headrests.
• Adjust inside and outside mirrors.
• Fasten the seat belt and ask all passen- gers to do likewise.
• Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-11). 1. Apply the parking brake.
2. Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
unless the shif t lever is in either P
(Park) or N (Neutral).
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while
depressing the brake pedal with the ig-
nition switch in any position.
• If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator
pedal a little (approximately 1/3 to the
floor) and while holding, crank the en-
gine. Release the accelerator pedal
when the engine starts.
• If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch to
the ON position to start cranking the
engine. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition
switch to the LOCK position. Af ter
cranking the engine, release the accel- erator pedal. Crank the engine with
your foot off the accelerator pedal by
depressing the brake pedal and push-
ing the ignition switch to start the
engine. If the engine starts, but fails to
run, repeat the above procedure.
CAUTION
Do not operate the starter for more
than 15 seconds at a time. If the engine
does not start, push the ignition switch
to the OFF position and wait 10 seconds
before cranking again, otherwise the
starter could be damaged.
4. Warm-up
Allow the engine to idle for at least 30
seconds af ter starting. Do not race the
engine while warming it up. Drive at a
moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of 2 to 3 minutes before shut-
ting it off. Starting and stopping the en-
gine over a short period of time may
make the vehicle more difficult to start.
5. To stop the engine, move the shif t lever to the P (Park) position and push the
ignition switch to the OFF position.

When canceling the manual shif t mode
Return the shif t lever to the D (Drive) posi-
tion to return the transmission to the nor-
mal driving mode.
Accelerator downshif t
— in D (Drive) position —
For passing or hill climbing, depress the
accelerator pedal to the floor. This shif ts
the transmission down into a lower gear,
depending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
when climbing steep grades in high tem-
peratures with heavy loads, such as when
towing a trailer), engine power and, under
some conditions, vehicle speed will be de-
creased automatically to reduce the
chance of transmission damage. Vehicle
speed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be limited.
Fail-safe
If the vehicle is driven under extreme
conditions, such as excessive wheel
spinning and subsequent hard braking,
the fail-safe system may be activated.
The Malfunction Indicator Light (MIL)
may come on to indicate the fail-safe
mode is activated. For additional infor-
mation, see “Malfunction Indicator Light
(MIL)” (P. 2-19). This will occur even if all
electrical circuits are functioning prop-
erly. In this case, place the ignition switch
in the OFF position and wait for 10 sec-
onds. Then push the switch back to the
ON position. The vehicle should return to
its normal operating condition. If it does
not return to its normal operating condi-
tion, have the transmission checked and
repaired, if necessary. It is recommended
that you visit a NISSAN dealer for this
service.
WARNING
When the high fluid temperature pro-
tection mode or fail-safe operation oc-
curs, vehicle speed may be gradually
reduced. The reduced speed may be
lower than other traffic, which could in-
crease the chance of a collision. Be es-
pecially careful when driving. If neces-
sary, pull to the side of the road at a safe
place and allow the transmission to re-
turn to normal operation, or have it re-
paired if necessary.
