–– If the surface temperature of thesteering-wheel is above the temperature
within which the system is designed to
operate, the system will not heat the
steering-wheel. This is not a malfunction. The air conditioner system in your INFINITI
vehicle is charged with a refrigerant designed
with the environment in mind.
This refrigerant does not harm the earth's
ozone layer.
Special charging equipment and lubricant is
required when servicing your INFINITI air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to your
air conditioner system. For additional infor-
mation, see “Air conditioner system refriger-
ant and oil recommendations” (P. 10-7).
It is recommended that you visit an INFINITI
retailer for servicing your “environmentally
friendly” air conditioning system.
WARNING
The air conditioner system contains refrig-
erant under high pressure. To avoid per-
sonal injury, any air conditioner service
should be done only by an experienced
technician with proper equipment. The vehicle is equipped with a shark fin an-
tenna and an antenna pattern is printed in-
side the rear window.
CAUTION
• Do not place metalized film near the rear
window glass or attach any metal parts
to it. This may cause poor reception or
noise.
• When cleaning the inside of the rear win-
dow, be careful not to scratch or damage
the rear window antenna. Lightly wipe
along the antenna with a dampened soft
cloth.

Additional information:
• When using a wheel without the TPMSsuch as the spare tire, the TPMS does not
monitor the tire pressure of the spare tire.
• The TPMS will activate only when the ve- hicle is driven at speeds above 16 mph (25
km/h). Also, this system may not detect a
sudden drop in tire pressure (for example, a
flat tire while driving).
• The low tire pressure warning light does not automatically turn off when the tire
pressure is adjusted. After the tire is in-
flated to the recommended pressure, the
vehicle must be driven at speeds above 16
mph (25 km/h) to activate the TPMS and
turn off the low tire pressure warning light.
Use a tire pressure gauge to check the tire
pressure.
• The “Tire Pressure Low — Add Air” warning appears in the vehicle information display
when the low tire pressure warning light is
illuminated and low tire pressure is de-
tected. The “Tire Pressure Low - Add Air”
warning turns off when the low tire pres-
sure warning light turns off.
• The “Tire Pressure Low — Add Air” warning appears each time the ignition switch is in
the ON position as long as the low tire
pressure warning light remains illuminated. • The “Tire Pressure Low — Add Air” warning
does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
• Tire pressure rises and falls depending on the heat caused by the vehicle’s operation
and the outside temperature. Do not re-
duce the tire pressure after driving because
the tire pressure rises after driving. Low
outside temperature can lower the tem-
perature of the air inside the tire which can
cause a lower tire inflation pressure. This
may cause the low tire pressure warning
light to illuminate. If the warning light illu-
minates, check the tire pressure for all four
tires.
• The Tire and Loading Information label is located in the driver's door opening.
• You can also check the pressure of all tires (except the spare tire) on the vehicle infor-
mation display screen. The order of the tire
pressure figures displayed on the screen
corresponds with the actual order of the
tire position.
For additional information, see “Low tire
pressure warning light” (P. 2-13) and “Tire
Pressure Low — Add Air” (P. 2-28).WARNING
• Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
• If the low tire pressure warning light illu-
minates 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 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 recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
off. If you have a flat tire, replace it with
a replacement tire as soon as possible.
(For additional information, see “Flat
tire” (P. 6-3) for changing a flat tire.)
5-6Starting and driving

AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe and
prudent manner may result in loss of con-
trol or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden steer-
ing maneuvers, because these driving prac-
tices could cause you to lose control of your
vehicle.
As with any vehicle, loss of control could re-
sult in a collision with other vehicles or ob-
jects or cause the vehicle to roll over, par-
ticularly if the loss of control causes the
vehicle to slide sideways.
Be attentive at all times, and avoid driving
when tired. Never drive when under the influ-
ence of alcohol or drugs (including prescrip-
tion or over-the-counter drugs which may
cause drowsiness). Always wear your seat
belt as outlined in the “Safety – Seats, seat
belts and supplemental restraint system” sec-
tion of this manual, and also instruct your
passengers to do so. Seat belts help reduce the risk of injury in
collisions and rollovers.
In a rollover crash, an unbelted person is sig-
nificantly more likely to die than a person
wearing a seat belt.
OFF-ROAD RECOVERY
While driving, the right side or left side wheels
may unintentionally leave the road surface. If
this occurs, maintain control of the vehicle by
following the procedure below. Please note
that this procedure is only a general guide.
The vehicle must be driven as appropriate
based on the conditions of the vehicle, road
and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel
with both hands and try to hold a straight
course.
4. When appropriate, slowly release the ac- celerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while vehicle
speed is reduced. Do not attempt to drive
the vehicle back onto the road surface
until vehicle speed is reduced. 6. When it is safe to do so, gradually turn the
steering wheel until both tires return to
the road surface. When all tires are on the
road surface, steer the vehicle to stay in
the appropriate driving lane.
• If you decide that it is not safe to return the vehicle to the road surface based on
vehicle, road or traffic conditions,
gradually slow the vehicle to a stop in a
safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving on
under-inflated tires.
Rapid air pressure loss can affect the han-
dling and stability of the vehicle, especially at
highway speeds.
Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspecting the tires for wear and damage. For
additional information, see “Wheels and tires”
(P. 8-27). If a tire rapidly loses air pressure or
“blows-out” while driving, maintain control of
the vehicle by following the procedure below.
Starting and driving5-9

Please note that this procedure is only a gen-
eral guide. The vehicle must be driven as ap-
propriate based on the conditions of the ve-
hicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
• 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 ac- celerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe loca- tion off the road and away from traffic if
possible. 5. Lightly apply the brake pedal to gradually
stop the vehicle.
6. Turn on the hazard warning flashers and contact a roadside emergency service to
change the tire. For additional informa-
tion, see “Flat tire” (P. 6-3).
DRINKING ALCOHOL/DRUGS
AND DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood of
being involved in an accident injuring your-
self and others. Additionally, if you are in-
jured in an accident, alcohol can increase
the severity of the injury.
INFINITI 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
accidents. 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!
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.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is mainly
designed for leisure use, unlike a conventional
off-road vehicle.
Remember that 2-Wheel Drive (2WD) mod-
els are less capable than All-Wheel Drive
(AWD) models for rough road driving and
extrication when stuck in deep snow or mud,
or the like.
Please observe the following precautions:
WARNING
• Spinning the front wheels on slippery
surfaces may cause the AWD warning
message to display and the AWD system
to automatically switch from the AWD
to the 2WD mode. This could reduce the
traction.
