–– If the surface temperature of thesteering-wheel is above the temperature
within which the system is designed to
operate, the system will not heat the
steering-wheel. This is not a malfunction. The air conditioner system in your INFINITI
vehicle is charged with a refrigerant designed
with the environment in mind.
This refrigerant does not harm the earth's
ozone layer.
Special charging equipment and lubricant is
required when servicing your INFINITI air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to your
air conditioner system. For additional infor-
mation, see “Air conditioner system refriger-
ant and oil recommendations” (P. 10-7).
It is recommended that you visit an INFINITI
retailer for servicing your “environmentally
friendly” air conditioning system.
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 proper equipment. The vehicle is equipped with a shark fin an-
tenna and an antenna pattern is printed in-
side the rear window.
CAUTION
• Do not place metalized film near the rear
window glass or attach any metal parts
to it. This may cause poor reception or
noise.
• When cleaning the inside of the rear win-
dow, be careful not to scratch or damage
the rear window antenna. Lightly wipe
along the antenna with a dampened soft
cloth.

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 number
of stops.
• Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency.
3. Use Air Conditioning (A/C) at Higher Ve-
hicle 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.
6. Plan for the Shortest Route
• Utilize a map or navigation system to determine the best route to save time. 7.
Avoid Idling
• Shutting off your engine when safe for stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
• Automated passes permit drivers to use special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.
9. 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 effec-
tively circulate the engine oil before
driving.
• Your vehicle will reach its ideal operat- ing temperature more quickly while driv-
ing versus idling.
10. 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 in-
side temperature faster, resulting in re-
duced demand on your A/C system.

FUEL RECOMMENDATION
Use unleaded premium gasoline with an oc-
tane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rat-
ing of at least 87 AKI number (Research oc-
tane number 91) may be temporarily used,
but only under the following precautions:
• Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as
possible.
• Avoid full throttle driving and abrupt acceleration.
Use unleaded premium gasoline for maxi-
mum vehicle performance.
CAUTION
• Using a fuel other than that specified
could adversely affect the emission con-
trol system, and may also affect the war-
ranty coverage.
• Under no circumstances should a leaded
gasoline be used, because this will dam-
age the three-way catalyst. •
Do not use a fuel containing more than
15% ethanol in your vehicle. Your vehicle
is not designed to run on a fuel contain-
ing more than 15% ethanol. Using a fuel
containing more than 15% ethanol in a
vehicle not specifically designed for a
fuel containing more than 15% ethanol
can adversely affect the emission control
devices and systems of the vehicle. Dam-
age caused by such fuel is not covered by
the INFINITI New Vehicle Limited
Warranty.

CAUTION
Damage to engine caused by improper
maintenance or use of incorrect oil and fil-
ter quality and/or viscosity is not covered
by the INFINITI New Vehicle Limited
Warranty.
Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter change
intervals depend upon how you use your
vehicle.
Operation under the following conditions
may require more frequent oil and filter
changes:
• repeated short distance driving at cold out- side temperatures
• driving in dusty conditions
• extensive idling
• stop and go commuting

RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFO-1234yf (R-1234yf) and the oil,
Genuine NISSAN A/C System Oil Type PAG
(ND-OIL12) or the exact equivalents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replacement
of all air conditioner system components.
The refrigerant HFO-1234yf (R-1234yf) in
your INFINITI vehicle does not harm the
earth's ozone layer. Although this refrigerant
does not affect the earth's atmosphere, cer-
tain government regulations require the re-
covery and recycling of any refrigerant during
automotive air conditioner system service. Air
conditioner system should only be serviced by
trained and certified technicians to ensure
proper and safe operation (SAE J2845). An
INFINITI retailer has the trained technicians
and equipment needed to recover and recycle
your air conditioner system refrigerant. Only
new and SAEJ2842 certified evaporator(s)
shall be used as replacement parts. A damaged or leaking air conditioning evapo-
rator shall never be repaired or replaced with
one removed from a used or salvaged vehicle.
To replace a damaged or leaking evaporator,
use only new and SAE J2842 certified
evaporator(s). It is recommended that you
visit an INFINITI retailer when servicing your
