nate in the following cases:
∙ When the shift lever is in the R (Reverse) position.
∙ When the vehicle speed is below 3 mph (4.8 km/h) or over 90 mph (144 km/h).
∙ When the Intelligent Cruise Control sys- tem (if so equipped) is operated.
ECO pedal system (if so equipped)
The ECO pedal system helps assist the driver
to improve fuel economy by increasing the
reaction force of the accelerator pedal. When
the ECO drive indicator light is blinking or
turns off, the ECO pedal system increases
the reaction force of the accelerator pedal.
5-30Starting and driving

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 Dis-
tances
∙ 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 unnec-
essary braking.
∙ Safely monitoring traffic to anticipate changes in speed permits reduced
braking 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 stop-
ping 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 ef-
fectively circulate the engine oil before
driving.
∙ Your vehicle will reach its ideal operat- ing temperature more quickly while
driving versus idling.
FUEL EFFICIENT DRIVING TIPS
5-172Starting and driving

10.Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible.
∙ 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. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases tire
wear and lowers fuel economy.
∙ Keep all the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer in-
formation” section of this manual. If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.

Relative humidity
Corrosion will be accelerated in areas of high
relative humidity, especially those areas
where the temperatures stay above freezing
and where atmospheric pollution exists and
road salt is used.
Temperature
High temperatures accelerate the rate of cor-
rosion to those parts which are not well ven-
tilated.
Air pollution
Industrial pollution, the presence of salt in the
air in coastal areas, or heavy road salt use
accelerates the corrosion process. Road salt
also accelerates the disintegration of paint
surfaces.
PROTECT YOUR VEHICLE FROM
CORROSION
∙ Wash and wax your vehicle often to keepthe vehicle clean.
∙ Always check for minor damage to the paint and repair it as soon as possible.
∙ Keep drain holes at the bottom of the doors open to avoid water accumulation. ∙ Check the underbody for accumulation
of sand, dirt or salt. If present, wash with
water as soon as possible.
CAUTION
∙ NEVER remove dirt, sand or other debrisfrom the passenger compartment by
washing it out with a hose. Remove dirt
with a vacuum cleaner or broom.
∙ Never allow water or other liquids to come in contact with electronic compo-
nents inside the vehicle as this may dam-
age them.
Chemicals used for road surface de-icing are
extremely corrosive. They accelerate corro-
sion and deterioration of underbody compo-
nents such as the exhaust system, fuel and
brake lines, brake cables, floor pan and fend-
ers.
In winter, the underbody must be cleaned
periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, it is recommended that you consult an
INFINITI retailer.
7-8Appearance and care

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
∙ Park the vehicle on a level surface, applythe parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Move the shift lever to P (Park).
∙ Be sure the ignition switch is in the OFF or LOCK position when performing any
parts replacement or repairs.
∙ 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 remove any jewelry,
such as rings, watches, etc. before work-
ing on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ Your vehicle is equipped with an auto-
matic 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 disconnect the negative battery
cable before working near the fan.
∙ If you must run the engine in an enclosed space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
∙ Never get under the vehicle while it is supported only by a jack. If it is necessary
to work under the vehicle, support it with
safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ Because the fuel lines on gasoline engine models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
∙ Do not work under the hood while theengine is hot. Turn the engine off and
wait until it cools down. ∙ Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
∙ Never leave the engine or Continuously Variable Transmission (CVT) related
component harnesses disconnected
while the ignition switch is in the ON
position.
∙ Never connect or disconnect the battery or any transistorized component while
the ignition switch is in the ON position.
