Instruments and controls2-25

WARNING
•The heater and air conditioner operate only
when the engine is running.
•Never leave children or adults who would
normally require the support of others alone
in the vehicle. Pets should not be left alone
either. They could unknowingly activate
switches or controls and inadvertently be-
come involved in a serious accident and in-
jure themselves. On hot, sunny days, tem-
peratures in a closed vehicle could quickly
become high enough to cause severe or
possibly fatal injuries to people or animals.
•Do not use the recirculation mode for long
periods as it may cause the interior air to
become stale and the windows to fog up.
•Do not adjust the heating and air condition-
ing controls while driving so that full atten-
tion may be given to vehicle operation.
The heater and air conditioner operate when the
engine is running. The air blower will operate
even if the engine is turned off and the ignition
switch is in the ON position.NOTE
•Condensation forms inside the air condition-
ing unit when the air conditioner (if
equipped) is running, and is safely dis-
charged underneath your vehicle.
Traces of water on the ground are therefore
normal.
•Odors from inside and outside the vehicle
can build up in the air conditioner unit. Odor
can enter the passenger compartment
through the ventilators.
When parking, set the heater and air condi-
tioner controls to turn off air recirculation to
allow fresh air into the passenger compart-
ment. This should help reduce odors inside
the vehicle.
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up. To prevent the windows from misting
up
•Switch off climate control only briefly.
•Switch on air-recirculation mode only
briefly.
•Switch on the cooling with air dehumidifica-
tion function.
•Switch on the windshield demisting function
briefly, if required.The air-conditioning system/automatic climate
control regulates the temperature and the hu-
midity of the vehicle interior and filters unde-
sirable substances from the air.
The air-conditioning system/automatic climate
control can only be operated when the engine is
running. Optimum operation is only achieved
with the side windows closed.
Always keep the ventilation flaps behind the
side panelling clear. Otherwise the vehicle will
not be ventilated correctly.
NOTE
•Ventilate the vehicle for a brief period during
warm weather. This will speed up the cooling
process and the desired interior temperature
will be reached more quickly.
•The integrated filter filters out most particles
of dust and soot and completely filters out
pollen. With automatic climate control, gas-
eous pollutants and odors will also be re-
duced. A clogged filter reduces the amount
of air supplied to the vehicle interior. For this
reason, you should always observe the inter-
val for replacing the filter, which is specified
in the Service Booklet. As this depends on
environmental conditions, e.g. heavy air pol-
lution, the interval may be shorter than
stated in the Service Booklet.

•After approximately 30 minutes at outside
temperatures above approximately 45oF(7oC) if the cooling with air dehumidification
function is activated.
SERVICING AIR CONDITIONER
WARNING
The air conditioner system contains refriger-
ant under high pressure. To avoid personal in-
jury, any air conditioner service should be
done only by an experienced technician with
the proper equipment.
The air conditioner system in your vehicle is
charged with a refrigerant designed with the
environment in mind.
This refrigerant will not harm the earth’s ozone
layer.
Special charging equipment and lubricant are
required when servicing your vehicle’s air con-
ditioner. Using improper refrigerants or lubri-
cants will cause severe damage to the air
conditioner system. (SeeAir conditioner sys-
tem refrigerant and oil recommendationsin the
9. Maintenance and Schedulessection.)
An INFINITI retailer will be able to service your
environmentally friendly air conditioner system.
Air conditioner filter
The air conditioner system is equipped with an
air conditioner filter. To make sure the air
conditioner heats, defogs, and ventilates effi-
ciently, replace the filter in accordance with the
specified maintenance intervals listed in the
separate maintenance booklet. It is recom-
mended you visit an INFINITI retailer for this
service.
The filter should be replaced if the air flow
decreases significantly or if windows fog up
easily when operating the heater or air condi-
tioner.

Wheel
bolt tightening torque: 96 ft-lb (130 N•m, 13
kg-m)
As soon as possible, tighten the wheel bolts to
the specified torque with a torque wrench.
The wheel bolts must be kept tightened to
specification at all times. It is recommended
that the wheel bolts be tightened to specifica-
tion at each maintenance interval.
Adjust the tire pressure to the COLD pressure.
COLD pressure is the tire pressure as measured
after the vehicle has been parked for three hours
or more or driven for less than 1 mile (1.6 km).
COLD tire pressures are shown on the tire and
loading information label affixed to the driver’s
side center pillar.
Wheel lock bolts(if equipped)
In order to prevent theft, the specially designed
wheel lock bolt is installed to each wheel. The
wheel lock bolt cannot be removed with the
commonly used tools.
When removing tires, use the lock key provided
with your vehicle.Removing the wheel lock bolt
:
1. Insert the wheel lock key1to the wheel
lock bolt.
2. To remove the wheel lock bolt, turn the
wheel lock key counterclockwise using the

CAUTION
•Do not use a power tool to remove the wheel
lock bolts.
•When installing the wheel, tighten the
wheel lock bolts to the same tightening
torque as the normal wheel bolts. For de-
tails, seeInstalling the wheelearlier in
this section.NOTE
•The wheel lock bolt has an individual code.
A wheel lock key with other than the indi-
vidual code cannot remove the wheel lock
bolt. If you lose the wheel lock key, it is
recommended you contact an INFINITI re-
tailer for a duplicate with the original wheel
lock key code.
•Record the key number and keep it in a safe
place, not in the vehicle.
•When you ask for a service at an INFINITI
retailer, make sure to keep the lock key in
the vehicle. Otherwise, wheels cannot be
removed and the service cannot be per-
formed.

•Tires degrade with age and use. Have tires,
including the spare, over 6 years old
checked by a qualified technician because
some tire damage may not be obvious. Re-
place the tires as necessary to prevent tire
failure and possible personal injury.
•Improper service of the spare tire may re-
sult in serious personal injury. If it is neces-
sary to repair the spare tire, it is recom-
mended that you visit an INFINITI retailer for
this service.
•For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the Warranty Information Booklet.
Tires should be periodically inspected for wear,
cracking, bulging or objects caught in the tread. If
excessive wear, cracks, bulging or deep cuts are
found, the tire should be replaced immediately.
The original tires have a built-in tread wear
indicator. When the wear indicator is visible,
the tire should be replaced.
Improper servicing of a tire may result in seri-
ous personal injury. If it is necessary to repair a
tire, it is recommended you contact an INFINITI
retailer.
TIRE ROTATION
INFINITI recommends rotating the tires every
5,000 miles (8,000 km).
For additional information on tire replacing
procedures, refer toFlat tirein the6. In case
of emergencysection.As soon as possible,
tighten the wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque: 96 ft-lb (130 N·m)
The wheel nuts must be kept tightened to speci-
fications at all times. It is recommended that
wheel nuts be tightened to specification at each
tire rotation interval.
WARNING
•After rotating the tires, check and adjust
the tire pressure.
•Do not include the spare tire in the tire
rotation.
•For additional information regarding tires,
refer toImportant Tire Safety Information
(US) orTire Safety Informationin the War-
ranty Information Booklet.
REPLACING WHEELS AND TIRES
WARNING
Do not install a deformed wheel or tire even if it
has been repaired. Such wheels or tires could
have structural damage and could fail without
warning.
When replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. (SeeWheels and Tiresin the9.
Maintenance and SchedulesMaintenance and
Schedulessection for recommended types and
sizes of tires and wheels.)
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, possibly
degraded vehicle handling characteristics
and/or interference with the brake discs/
drums. Such interference can lead to decreased
braking efficiency and/or early brake pad/shoe
wear.
