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.

5-3PRECAUTIONS WHEN STARTING AND
DRIVING

Black plate (324,1)
[ Edit: 2012/ 1/ 17 Model: V36-D ]5-4 Starting and drivingTHREE-WAY CATALYST GUID-86566321-839C-449F-B115-5E0F54C18ECE
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 system
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 seriously reduce
the three-way catalyst ’ s ability to help
reduce exhaust pollutants.
. Keep your engine tuned up. Malfunctions
in the ignition, fuel injection, or elec-
trical 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 noticeable loss of
performance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly by an INFINITI retai-
ler.
. 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 SYS-
TEM (TPMS) GUID-01A54468-A798-4FEE-AB71-4E7737FDCB1C
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 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.
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 malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one

. 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
accelerator 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 gradu-
ally stop the vehicle.
6. Turn on the hazard warning flashers
and either contact a roadside emer-

Owner ’ s Manual. DRINKING ALCOHOL/DRUGS AND
DRIVING GUID-9FACE374-80C0-473A-AF0E-37D9C4BE0B25
WARNING Never drive under the influence of alcohol or
drugs. Alcohol in the bloodstream reduces
coordination, delays reaction time and im-
pairs 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.
INFINITI 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 accidents. Although 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!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs). Don ’ t drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or
some other physical condition.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS GUID-A083649A-0774-46ED-A3DF-AB198E309722
WARNING . Do not drive beyond the performance
capability of the tires, even with AWD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
. 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.
. 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

Black plate (329,1)
[ Edit: 2012/ 1/ 17 Model: V36-D ]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. GUID-A0F35CA1-ADE1-478F-ABDB-FB4DD4BF0426
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 3 consecutive
times 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.
Before operating the push-button ignition
switch, be sure to move the selector lever
to the P (Park) position (for automatic
transmission model) or the shift lever to
the N (Neutral) position (for manual trans-
mission model).
