Automatic Climate Control System
(if so equipped)
The Automatic Climate Control System
keeps the air inside of the vehicle clean, using
the automatic air recirculation control with
the exhaust gas/outside odor detecting sen-
sor with ion control.
1Auto Recirc key
Touch to turn on the automatic recirculation
mode.
2Plasmacluster® icon
Indicates the Plasmacluster® ion emission
status.
Ion control:
The Automatic Climate Control System unit
generates highly concentrated Plasmaclus-
ter® ions into the air blown from the ventila-
tors to reduce odor absorbed into the interior
trim and to suppress airborne bacteria. The high-density Plasmacluster®ions also have a
proven skin moisture preserving effect.
The Plasmacluster® icon on the CLIMATE
screen indicates the status of the Plasma-
cluster® ion emission from the system and
changes with the amount of the air flow.
Automatic air recirculation control with the
exhaust gas/outside odor detection sensor:
The Automatic Climate Control System
comes with an exhaust gas
detection/outside odor sensor. When the au-
tomatic air circulation control is activated, the
sensor detects odors outside the vehicle such
as pulp or chemicals, and exhaust such as
gasoline or diesel. When such odors or gases
are detected the display and the system au-
tomatically change from fresh air mode to the
recirculation mode.
When the automatic air recirculation is on, for
the first 5 minutes, the air recirculation mode
is selected to prevent dust, dirt, and pollen
from entering the vehicle and to clean the air
inside of the vehicle.
After 5 minutes, the sensor detects exhaust
gas and automatically alternates between
the air recirculation mode and the fresh air
mode.

∙ Auto Steering Wheel Heater
The automatic control mode for the
steering-wheel heating can be turned on
and off. When the item is turned on, the
steering-wheel heating will turn on auto-
matically if the temperature inside the
vehicle compartment is low at the time
when the ignition switch is turned on.
Regardless of the temperature, the
steering-wheel heating will turn off after
30 minutes. If the steering-wheel heater
is turned on or off manually by
touchingon the CLIMATE screen,
the automatic steering-wheel heating
control mode will be canceled and will
return to the manual mode.
∙ If the surface temperature of the steering-wheel is above the tempera-
ture within which the system is de-
signed 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, refer to “Air conditioner system re-
frigerant and oil recommendations” in the
“Technical and consumer information” sec-
tion of this manual.
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.

When installing a CB, ham radio or car phone
in your vehicle, be sure to observe the follow-
ing precautions; otherwise, the new equip-
ment may adversely affect the engine control
system and other electronic parts.
WARNING
∙ A cellular phone should not be used forany purpose while driving so full atten-
tion may be given to vehicle operation.
Some jurisdictions prohibit the use of cel-
lular phones while driving.
∙ If you must make a call while your vehicle is in motion, the hands free cellular phone
operational mode is highly recom-
mended. Exercise extreme caution at all
times so full attention may be given to
vehicle operation.
∙ If you are unable to devote full attention to vehicle operation while talking on the
phone, pull off the road to a safe location
and stop your vehicle.
CAUTION
∙ Keep the antenna as far away as possiblefrom the electronic control modules.
∙ Keep the antenna wire more than 8 in (20 cm) away from the electronic control
system harnesses. Do not route the an-
tenna wire next to any harness.
∙ Adjust the antenna standing-wave ratio as recommended by the manufacturer.
∙ Connect the ground wire from the CB ra- dio chassis to the body.
∙ For additional information,, it is recom- mended that you visit an INFINITI re-
tailer for servicing.

DOT (Department of Transportation) Quality
Grades: All passenger car tires must conform
to federal safety requirements in addition to
these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one and
one-half (1 1/2) times as well on the govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon the
actual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.
Traction AA, A, B and C
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions onspecified government test surfaces of as-
phalt and concrete. A tire marked C may have
poor traction performance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature A, B and C
The temperature grades are A (the highest),
B, and C, representing the tire’s resistance to
the generation of heat, and its ability to dis-
sipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the material of the tire to degenerate
and reduce tire life, and excessive tempera-
ture can lead to sudden tire failure. The grade
C corresponds to a level of performance
which all passenger car tires must meet under
the Federal Motor Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this tire is es-
tablished for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, either
separately or in combination, can cause
heat build-up and possible tire failure.
