WARNING
. The air conditioner cooling function
operates only when the engine is
running.
. 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. 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.
. 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.
Start the engine and operate the automatic
climate control system.
VENTILATORS HEATER AND AIR CONDITIONER

NOTE:
.Odors from inside and outside the
vehicle can build up in the air conditioner
unit. Odor can enter the passenger
compartment through the vents.
. When parking, set the heater and air
conditioner controls to turn off air
recirculation to allow fresh air into the
passenger compartment. This should
help reduce odors inside the vehicle.

LINKING INTELLIGENT KEY
The Climate control system settings can be
memorized for each Intelligent Key. For
more details, see “Setting memory function”
(P.3-30).
SERVICING CLIMATE CONTROL
The climate control 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. However,
special charging equipment and lubricant are
required when servicing your INFINITI air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to your
climate control system. (See “Capacities and
recommended fluids/lubricants” (P.10-2)
for climate control system refrigerant and
lubricant recommendations.)
Your INFINITI retailer will be able to service
your environmentally friendly climate control
system.
WARNING
The system contains refrigerant under
high pressure. To avoid personal injury,
any air conditioner service should be
done only by an experienced technician
with the proper equipment.
In-cabin microfilter
The climate control system is equipped with
a natural grape seed polyphenol filter which
collects and neutralizes dirt, pollen, dust,
allergens (such as cedar pollen, tick shells)
etc. To make sure that the air conditioner
heats, defogs and ventilates efficiently, re-
place the filter in accordance with the
specified maintenance intervals listed in the
“9. Maintenance and schedules” section. It is
recommended to see an INFINITI retailer to
replace the filter.
The filter should be replaced if the air flow
decreases significantly or if windows fog up
easily when operating the heater or air
conditioner.

.Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
. Allow greater following distances on
slippery roads.
. Watch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steer-
ing maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist in
cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F
(−7°C) or lower.
To use the engine block heater
1. Turn the engine off.
2. Open the hood and unwrap the engine
block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2 - 4 hours, depending on
outside temperatures, to properly warm
the engine coolant. Use an appropriate
timer to turn the engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
WARNING
.Do not use your engine block heater
with an ungrounded electrical system
or a 2-pronged adapter. You can be
seriously injured by an electrical
shock if you use an ungrounded
connection.
. Disconnect and properly store the
engine block heater cord before starting the engine. Damage to the
cord could result in an electrical shock
and can cause serious injury.
. Use a heavy-duty 3-wire, 3-pronged
extension cord rated for at least 10A.
Plug the extension cord into a Ground
Fault Interrupt (GFI) protected,
grounded 110-VAC outlet. Failure
to use the proper extension cord or
a grounded outlet can result in a fire
or electrical shock and cause serious
personal injury.

WARNING
Always follow the instructions below.
Failure to do so could result in damage to
the charging system and cause personal
injury.
1. If the booster battery is in another vehicle
, position the two vehicles (and) to bring their batteries into close
proximity to each other.
Do not allow the two vehicles to touch.
2. Apply parking brake. Move the shift lever to the P (Park) position. Switch off all
unnecessary electrical systems (light,
heater, air conditioner, etc.).
3. Remove vent caps on the battery (if so equipped). Cover the battery with a
firmly wrung out moist cloth
to reduce
explosion hazard.
4. Connect jumper cables in the sequence as illustrated (
???).
For models with a steering wheel lock
mechanism: If the battery is discon-
nected or discharged, the steering wheel
will lock and cannot be turned. Supply
power using jumper cables before push-
ing the ignition switch and disengaging
the steering lock.

6-12In case of emergency
CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle fire.
. To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the
radiator cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc., take the following
steps:
1. Move the vehicle safely off the road, apply the parking brake and move the
shift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
3. If engine overheating is caused by climb- ing a long hill on a hot day, run the engine at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off the
engine.) Do not open the hood further
until no steam or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is
leaking or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan can start at any time.
7. After the engine cools down, check the coolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired. It is recommended you
visit an INFINITI retailer for this service.
IF YOUR VEHICLE OVERHEATS

8-10Do-it-yourself
until it reaches normal operating tempera-
ture. Add coolant up to the MAX level.
Tighten the cap securely after adding engine
coolant.
If the cooling system requires coolant fre-
quently, have it checked. It is recommended
you visit an INFINITI retailer for this
service.
CHANGING ENGINE COOLANT
It is recommended that major cooling system
repairs be performed by an INFINITI retailer.
The service procedures can be found in the
appropriate INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
. To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
. Never remove the radiator cap when
the engine is hot. Serious burns could
be caused by high pressure fluid
escaping from the radiator.
. Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as soon as possible.
. Keep coolant out of reach of children
and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.
