SERVICING AIR CONDITIONER
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 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
conditioner. Using improper refrigerants or
lubricants will cause severe damage to the air
conditioner system. (See "Air conditioner sys-
tem refrigerant and oil recommendations".)
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 ef-
ficiently, replace the filter in accordance with
the specified maintenance intervals listed in
the separate maintenance booklet. It is rec-
ommended 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 con-
ditioner.

Follow these easy-to-use Fuel Efficient Driv-
ing 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 com-
muting 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 num-
ber of stops.
•Maintaining a steady speed can mini-
mize 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 le-
gally allowed) can improve fuel effi-
ciency 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
driving 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 deter-
mine the best route to save time.6.Avoid Idling
•Shutting off your engine when safe for
stops exceeding 30 seconds saves fuel
and reduces emissions.
7.Buy an Automated Pass for Toll Roads
•Automated passes permit drivers to
use special lanes to maintain cruising
speed through the toll and avoid stop-
ping and starting.
8.Winter Warm Up
•Limit idling time to minimize impact to
fuel economy.
•Vehicles typically need no more than
30 seconds of idling at start-up to ef-
fectively circulate the engine oil before
driving.
•Your vehicle will reach its ideal operat-
ing temperature more quickly while
driving versus idling.
9.Keeping your Vehicle Cool
•Park your vehicle in a covered parking
area or in the shade whenever possible.
•When entering a hot vehicle, opening
the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system.
FUEL EFFICIENT DRIVING TIPS
Starting and driving5-85

•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 injury. Therefore, quickly move your
foot from the brake pedal to the accel-
erator 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 accel-
erator 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 be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent 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, see
"Engine cooling system".
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
"Battery" 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, see "Changing engine
coolant" of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads,
INFINITI recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
an INFINITI retailer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit their use. Check local, state and pro-
vincial laws before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
COLD WEATHER DRIVING
5-96Starting and driving

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
retailer 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.For the jump-starting procedure, use only the
jump-starting connection point, consisting of
a positive terminal and an earth point, in the
engine compartment.
WARNING
•If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also dam-
age your vehicle.
•Explosive hydrogen gas is always pres-
ent in the vicinity of the battery. Keep all
sparks and flames away from the bat-
tery.
•Do not allow battery fluid to come into
contact with eyes, skin, clothes or
painted surfaces. Battery fluid is a cor-
rosive sulfuric acid which can cause se-
vere burns. If the fluid should come into
contact with anything, immediately
flush the contacted area with water.
•Keep the battery out of the reach of chil-
dren.
•The booster battery must be rated at
12 volts. Use of an improperly rated bat-
tery can damage your vehicle.
•Whenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
•Do not attempt to jump start a frozen
battery. It could explode and cause seri-
ous injury.
•Your vehicle has an automatic engine
cooling fan. It could come on at any time.
Keep hands and other objects away
from it.
