LINKING INTELLIGENT KEY
The Climate control system settings can be
memorized for each Intelligent Key. For
more details, see “Setting memory function”
(P.3-29).
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.

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 the 12-volt battery and
fuse box 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. Connect jumper cables in the sequence as illustrated (
???).
For models with a steering wheel lock
mechanism: If the 12-volt battery is
disconnected or discharged, the steering
wheel will lock and cannot be turned.

fore pushing the ignition switch and
disengaging the steering lock.
CAUTION
. Always connect positive (+) to posi-
tive (+) and negative (−) to body
ground (as illustrated) − not to the
12-volt battery.
. Make sure the jumper cables do not
touch moving parts in the engine
compartment and that clamps do
not contact any other metal.
4. Start the engine of the booster vehicle
and let it run for a few minutes.
5. Start the hybrid system of the vehicle being jump started

NOTE:
If it is not possible to turn the hybrid system
ON by following this procedure, it is
recommended that you contact an INFINITI
retailer immediately.Do not attempt to start the engine by
pushing.
CAUTION
.
Automatic transmission models can-
not be push-started or tow-started.
Attempting to do so may cause
transmission damage.
. Three way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.
. Never try to start the vehicle by
towing it; when the engine starts,
the forward surge could cause the
vehicle to collide with the tow vehi-
cle.
. Hybrid models cannot be push-
started or tow-started. Attempting
to do so may cause electrical or
transmission damage.
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 turn the INFINITI Direct Re-
sponse Hybrid
®System off.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant level
is below MIN
, open the reservoir tank cap
and add coolant up to the MAXlevel. If the
reservoir tank is empty, check the coolant
level in the radiator when the engine is cold.
If there is insufficient coolant in the radiator,
fill the radiator with coolant up to the filler
opening and also add it to the reservoir tank
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.

9-4Maintenance and schedules
properly.
Windshield defroster:Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and
that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
12-volt battery*: Check the fluid level in
each cell. It should be between the MAX and
MIN lines. Vehicles operated in high tem-
peratures or under severe condition require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential 12-volt battery
discharge and potential no-start conditions
such as:
1. Installation or extended use of electro-
nic accessories that consume 12-volt
battery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.)
2. Vehicle is not driven regularly and/or
only driven short distances. In these cases, the 12-volt battery may
need to be charged to maintain 12-volt
battery health.
Brake fluid level*:
Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the INFINITI Direct Response
Hybrid®System. Wait more than 15 minutes
for the oil to drain back into the oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting and
driving” (P.5-4) for exhaust gas (Carbon
monoxide).)
Fluid leaks: Check under the vehicle for fuel,
oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.
Inverter coolant level: Check the coolant
level when the inverter is cold. Power steering fluid level* and lines:
Check
the level when the fluid is cold, with the
hybrid system off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.
