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.

CAUTION
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of
this teach-in process.
Brake pads/linings and rotors that are either
new or have been replaced only achieve opti-
mum braking effect after several hundred
miles of driving. Compensate for the reduced
braking effect by applying greater force to the
brake pedalFollow these easy-to-use Fuel Efficient Driving
Tips to help you achieve the most fuel economy
from your vehicle.
1.Use Smooth Accelerator and Brake Pedal
Application
•Avoid rapid starts and stops.
•Use smooth, gentle accelerator and brake
application whenever possible.
•Maintain constant speed while commut-
ing and coast whenever possible.
2.Maintain Constant Speed
•Look ahead to try and anticipate and
minimize stops.
•Synchronizing your speed with traffic lights
allows you to reduce your number of stops.
•Maintaining a steady speed can minimize
red light stops and improve fuel efficiency.
3.Use Air Conditioning (A/C) at Higher Vehicle
Speeds
•Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load.
•Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the vehicle due
to increased aerodynamic drag.
•Recirculating the cool air in the cabin
when the A/C is on reduces cooling load.
4.Drive at Economical Speeds and Distances
•Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where legally
allowed) can improve fuel efficiency due
to reduced aerodynamic drag.
•Maintaining a safe following distance
behind other vehicles reduces unneces-
sary braking.
•Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes.
•Select a gear range suitable to road
conditions.
5.Use Cruise Control
•Using cruise control during highway driv-
ing helps maintain a steady speed.
•Cruise control is particularly effective in
providing fuel savings when driving on
flat terrains.
Utilize a map or navigation system to determine
the best route to save time.
FUEL EFFICIENT DRIVING TIPS
5-82Starting and driving

WARNING
•Never rely solely on the Hill Start Assist
(HSA) system to prevent the vehicle from
moving backward on a hill. Always drive
carefully and attentively. Depress the brake
pedal when the vehicle is stopped on a
steep hill. Be especially careful when
stopped on a hill on frozen or muddy roads.
Failure to prevent the vehicle from rolling
backwards may result in a loss of control of
the vehicle and possible serious injury or
death.
•The Hill Start Assist system is not designed
to hold the vehicle at a standstill on a hill.
Depress the brake pedal when the vehicle is
stopped on a steep hill. Failure to do so may
cause the vehicle to roll backwards and may
result in a collision or serious personal in-
jury.
•The Hill Start Assist system may not pre-
vent the vehicle from rolling backwards on a
hill under all load or road conditions. Al-
ways be prepared to depress the brake
pedal to prevent the vehicle from rolling
backwards. Failure to do so may result in a
collision or serious personal injury.
•After a short time, hill start assist will no
longer brake your vehicle and it could roll
away There is a risk of an accident and in-
jury. Therefore, quickly move your foot from
the brake pedal to the accelerator pedal.
Never leave the vehicle when it is held by
hill start assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll.
Hill start assist is not active if
•You are pulling away on a level road or a
downhill gradient.
•On vehicles with automatic transmission,
the transmission is in position N.
•The electric parking brake is applied.
•VDC is malfunctioning.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole, or use the INFINITI Intelligent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C), check the
antifreeze to assure proper winter protection. For
additional information, seeEngine cooling
systemin the8. Do-it-yourselfsection.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
Batteryin the8. Do-it-yourselfsection of this
manual.
DRAINING OF ENGINE COOLANT
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, seeChanging engine
coolantin the8. Do-it-yourselfsection of this
manual.

WARNING
•Do not continue to drive if your vehicle over-
heats. Doing so could cause engine damage
or a vehicle fire.
•To avoid the danger of being scalded, never
remove the radiator or coolant reservoir cap
while the engine is hot. When the radiator or
coolant reservoir cap is removed, pressur-
ized hot water will spurt out, possibly caus-
ing serious injury.
•Do not open the hood if steam is coming
out.
If the engine of your vehicle is overheating
(indicated by the engine coolant temperature
gauge) or if you feel a lack of engine power,
detect unusual noise, etc., proceed as follows:
1. Move and park the vehicle safely off the
road and away from traffic.
2. Turn on the hazard warning flasher lights.
3. Apply the parking brake.
4. Press the P (Park) button.
DO NOT STOP THE ENGINE.
5. Open all windows.6. Switch off the air conditioner system (if
equipped).
7. Set the heater or air conditioner tempera-
ture control to maximum “HOT” and fan
speed control to maximum speed.
8. Exit the vehicle.
9. Visually inspect and listen for steam or
coolant escaping from the radiator before
opening the hood.WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
10. Open the hood. For details, seeHoodin
the3. Pre-driving checks and adjustments
section.
11. Visually check if the cooling fan is running.
12. Visually check the radiator and radiator
hoses for leakage.
WARNING
Be careful not to allow your hands, hair, jew-
elry or clothing to come into contact with, or
get caught in, engine belts or the engine cool-
ing fan. The engine cooling fan can start at any
time.
13. After the engine cools down, check the
coolant level in the engine coolant reservoir
with the engine running.Do not open the
radiator cap (if equipped).
14. If the level is low, remove the engine
coolant reservoir cap and add coolant
slowly into the reservoir. After refilling the
reservoir to the MAX level, install the res-
ervoir cap.
15. Close the hood.
Have your vehicle inspected or repaired. It is
recommended you visit an INFINITI retailer.

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
•Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from moving.
Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the en-
gine is hot. Always turn off the engine and
wait until it cools down.
•If you must work with the engine running,
keep your hands, clothing, hair and tools
away from moving fans, belts and any other
moving parts.
•It is advisable to secure or remove any loose
clothing and any jewelry, such as rings,
watches, etc. before working on your ve-
hicle.
•If you must run the engine in an enclosedspace such as a garage, be sure there is
proper ventilation for exhaust gases to es-
cape.
•Never get under the vehicle while it is sup-
ported by a jack.
•Keep smoking materials, flame and sparks
away from fuel and the battery.
•Never connect or disconnect either the bat-
tery or any transistorized component con-
nector while the ignition switch is in the ON
position.
•On gasoline engine models with the Multi-
port Fuel Injection system, the fuel filter and
fuel lines should be serviced by an INFINITI
retailer or qualified workshop because the
fuel lines are under high pressure even
when the engine is turned off.
•Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
switch is in the OFF position and the engine
is not running. To avoid injury, always dis-
connect the negative battery cable before
working near the fan.
•Always wear eye protection whenever you
work on your vehicle.
•Never leave the engine or the transmission
related component harness connector dis-
connected while the ignition switch is in the
ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle flu-
ids can hurt the environment. Always con-
form to local regulations for disposal of ve-
hicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage.If in doubt about any
servicing, it is recommended you have it done by
an INFINITI retailer.
