WARNING. Do not adjust the steering wheel while
driving. You could lose control of your
vehicle and cause an accident.
. Do not adjust the steering wheel any
closer to you than is necessary for
proper steering operation and comfort.
The driver ’ s air bag inflates with great
force. If you are unrestrained, leaning
forward, sitting sideways or out of
position in any way, you are at greater
risk of injury or death in a crash. You
may also receive serious or fatal injuries
from the air bag if you are up against it
when it inflates. Always sit back against
the seatback and as far away as practical
from the steering wheel. Always use the
seat belts. SPA2328

to help avoid damaging the vehicle. The
system will not detect small objects below
the bumper and may not detect objects
close to the bumper or on the ground.
WARNING . The rearview monitor is a convenience
but it is not a substitute for proper
vehicle operation because it has areas
where objects cannot be viewed. Always
look out the windows and check mirrors
to be sure that it is safe to move before
operating the vehicle. Always operate
the vehicle slowly.
. 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 like ones viewed in the inside

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) GUID-FE83F1BB-566B-418F-8146-74C3A55C538A
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
windows 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 trunk lid closed while driving,
otherwise exhaust gases could be drawn
into the passenger compartment. If you
must drive with the trunk lid open,
follow these precautions:
1) Open all the windows.
2) Set the
air recirculation to off
and the fan control 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 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 involving
damage to the exhaust system,
underbody, or rear of the vehicle.

TIRE PRESSURE MONITORING SYS-
TEM (TPMS) GUID-EFDE8E6D-AFA0-4243-A90D-0D01CCEE6814
This 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 on 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.2-12) and “ Tire Pressure Mon-
itoring System (TPMS) ” (P.5-4).
WARNING . If the low tire pressure warning light
illuminates 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 damageROADSIDE ASSISTANCE PROGRAM EMERGENCY ENGINE SHUT OFF FLAT TIRE

[ Edit: 2012/ 1/ 17 Model: V36-D ]the tires and increase the likelihood of
tire failure. 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
cause a malfunction of the tire pressure sensors.
