REARVIEW MONITOR SYSTEM
LIMITATIONS
WARNING
Listed below are the system limitations
for RearView Monitor. Failure to oper-
ate the vehicle in accordance with
these system limitations could result in
serious injury or death.
• The system cannot completely elimi-
nate blind spots and may not show
every object.
• Underneath the bumper and the cor-
ner areas of the bumper cannot be
viewed on the RearView Monitor be-
cause of its monitoring range limita-
tion. The system will not show small
objects below the bumper, and may
not show objects close to the bum-
per or on the ground.
• Objects viewed in the RearView
Monitor differ from actual distance
because a wide-angle lens is used.
• Objects in the RearView Monitor will
appear visually opposite compared
to when viewed in the rearview and
outside mirrors. •
Use the displayed lines as a refer-
ence. The lines are highly affected by
the number of occupants, fuel level,
vehicle position, road conditions and
road grade.
• Make sure that the trunk is securely
closed when backing up.
• Do not put anything on the rearview
camera. The rearview camera is in-
stalled above the license plate.
• When washing the vehicle with high
pressure water, be sure not to spray it
around the camera. Otherwise, water
may enter the camera unit causing
water condensation on the lens, a
malfunction, fire or an electric shock.
• Do not strike the camera. It is a preci-
sion instrument. Otherwise, it may
malfunction or cause damage result-
ing in a fire or an electric shock. The following are operating limitations and
do not represent a system malfunction:
• When the temperature is extremely high
or low, the screen may not clearly display
objects.
• When strong light directly shines on the camera, objects may not be displayed
clearly.
• Vertical lines may be seen in objects on the screen. This is due to strong reflected
light from the bumper.
• The screen may flicker under fluorescent light.
• The colors of objects on the RearView Monitor may differ somewhat from the
actual color of objects.
• Objects on the monitor may not be clear in a dark environment.
• There may be a delay when switching between views.
• If dirt, rain or snow accumulate on the camera, the RearView Monitor may not
display objects clearly. Clean the camera.
• Do not use wax on the camera lens. Wipe off any wax with a clean cloth dampened
with a diluted mild cleaning agent, then
wipe with a dry cloth.

• Do not use the Intelligent Around
View® Monitor with the outside mir-
rors in the stored position, and make
sure that the trunk is securely closed
when operating the vehicle using the
Intelligent Around View® Monitor.
•
The apparent distance between ob-
jects viewed on the Intelligent Around
View® Monitor differs from the actual
distance.
• The cameras are installed on the
front grille, the outside mirrors and
above the rear license plate. Do not
put anything on the vehicle that cov-
ers the cameras.
• When washing the vehicle with high
pressure water, be sure not to spray
it around the cameras. Otherwise,
water may enter the camera unit
causing water condensation on the
lens, a malfunction, fire or an electric
shock.

WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves 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 seri-
ously injured. 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 car-
bon monoxide. Carbon monoxide
is dangerous. It can cause uncon-
sciousness or death. •
If you suspect that exhaust fumes
are entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
• Do not run the engine in closed
spaces such as a garage.
• Do not park the vehicle with the en-
gine running for any extended length
of time.
•
Keep the rear vent windows, lif tgates,
doors and trunk lids (if so equipped)
closed while driving, otherwise ex-
haust gases could be drawn into the
passenger 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
recommendation to prevent carbon
monoxide entry 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 involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
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.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-4Starting and driving

5. Lightly apply the brake pedal to gradu-ally stop the vehicle.
6. Turn on the hazard warning flashers and contact a roadside emergency service
to change the tire. For additional infor-
mation, see “Changing a flat tire” (P. 6-4).
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alco-
hol or drugs. Alcohol in the blood-
stream reduces coordination, delays
reaction time and impairs judgement.
Driving af ter drinking alcohol increases
the likelihood of being involved in an
accident injuring yourself and others.
Additionally, if you are injured in an ac-
cident, alcohol can increase the sever-
ity of the injury.
NISSAN is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
collisions. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people dif-
ferently 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 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 less than
1.5 seconds or the ignition switch is
pushed and held for more than 2 sec-
onds.) If the engine stops while the ve-
hicle is being driven, this could lead to a
crash and serious injury.
PUSH-BUTTON IGNITION SWITCH

6-8In case of emergency

Two-Wheel Drive models with
Continuously Variable
Transmission (CVT)
NISSAN recommends that your vehicle be
towed with the driving (front) wheels off the
ground or place the vehicle on a flatbed
truck as illustrated.
CAUTION
• Never tow CVT models with the front
wheels on the ground or four wheels
on the ground (forward or back-
ward), as this may cause serious and
expensive damage to the transmis-
sion. If it is necessary to tow the ve-
hicle with the rear wheels raised al-
ways use towing dollies under the
front wheels. •
When towing CVT models with the
rear wheels on the ground or on tow-
ing dollies:
– Place the ignition switch in the
OFF position, and secure the
steering wheel in a straight-ahead
position with a rope or similar de-
vice. Never secure the steering
wheel by placing the ignition
switch in the LOCK position. This
may damage the steering lock
mechanism (for models with a
steering lock mechanism).

•Properly position the mats in the
floorwell using the floor mat posi-
tioning hook. For additional informa-
tion, see "Floor mat installation"
(P. 7-8).
• Make sure the floor mat does not in-
terfere with pedal operation.
•
Periodically check the floor mats to
make sure they are properly installed.
• Af ter cleaning the vehicle interior,
check the floor mats to make sure
they are properly installed.
The use of Genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular clean-
ing and replaced if they become exces-
sively worn.
Floor mat installation
Your vehicle is equipped with floor mat po-
sitioning hook(s). The number and shape of
the floor mat positioning hooks for each
seating position varies depending on the
vehicle. When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition switch in the OFF posi-
tion, the shif t lever in P (Park) position
and with the parking brake fully applied,
position the floor mat in the floorwell so
that the floor mat grommet holes are
aligned with the hook(s).
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is
properly positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion switch still in the OFF position, the
shif t lever in the P (Park) position and
with the parking brake applied, fully ap-
ply and release all pedals. The floor mat
must not interfere with pedal operation
or prevent the pedal from returning to
its normal position.
It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle. The illustration shows the location of the
