.Underneath the bumper and the corner
areas of the bumper cannot be viewed on
the RearView Monitor because of its
monitoring range limitation. The system
will not show small objects below the
bumper, and may not show objects close
to the bumper 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 than when
viewed in the rear view and outside
mirrors.
. 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 precision
instrument. Otherwise, it may malfunc-
tion or cause damage resulting in a fire or an electric shock.
CAUTION
There is a plastic cover over the camera. Do

WARNING
.Do not leave children or adults who
would normally require the support of
others alone in your vehicle. Pets should
not be left alone either. 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 play-
ing and becoming locked in the trunk
where they could be seriously 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)Y51D-V-E01-BD7897F9-A61E-41DB-ADF1-D5A23F7D7029
WARNING
.Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death.

follow the manufacturer’s recommenda-
tion to prevent carbon monoxide entry
into the vehicle.
. The exhaust system and body should be
inspected by a qualified mechanic when-
ever:
—The vehicle is raised for service.
—You suspect that exhaust fumes are
entering into the passenger compart-
ment.
—You notice a change in the sound of
the exhaust system.
—You have had an accident involvingdamage to the exhaust system,

and drive carefully.
. This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
. For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any D (Drive) or R (Reverse) position with
the engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result in
serious vehicle damage or personal
injury.
. Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer,
(such as the dynamometers used by
some states for emissions testing), or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury. .
When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.

TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
Y51D-V-E01-BFEA3614-E51F-4536-91BF-65C5324E7C3EThis vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears in the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.
If the vehicle is being driven with low tire
pressure, the TPMS will activate and warn
you of it by the low tire pressure warning
light. This system will activate only when
the vehicle is driven at speeds above 16
MPH (25 km/h). For more details, see
“Warning/indicator lights and audible re-
minders” (P.2-10) and “Tire Pressure Mon-
itoring System (TPMS)” (P.5-4).
WARNING
.If the low tire pressure warning light
illuminates or LOW PRESSURE informa-
tion is displayed on the monitor screen
while driving, avoid sudden steering
maneuvers or abrupt braking, reduce
vehicle speed, pull off the road to a safe
location and stop the vehicle as soon as possible. Driving with under-inflated
tires may permanently damage the tires
and increase the likelihood of tire fail-
ure. Serious vehicle damage could occur
and may lead to an accident and could
result in serious personal injury. Check
the tire pressure for all four tires. Adjust
the tire pressure to the recommended
COLD tire pressure shown on the Tire
and Loading Information label to turn
the low tire pressure warning light OFF. If
the light still illuminates while driving
after adjusting the tire pressure, a tire
may be flat. If you have a flat tire,
replace it with a spare tire as soon as
possible.
. When a spare tire is mounted or a wheel
is replaced, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.
. Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
. Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
