– When your vehicle or the vehicle orpedestrian ahead moves quickly or
significantly such that the system
cannot detect and react in time (for
example, pedestrian moving quickly
toward the vehicle at close range, ve-
hicle cutting in, changing lanes, mak-
ing a turn, steering abruptly, sudden
acceleration or deceleration).
– When the vehicle or pedestrian is off-
set from the vehicle’s forward path.
– If the speed difference between the two vehicles is small.
– The pedestrian’s profile is partially obscured or unidentifiable; for ex-
ample, due to transporting luggage,
pushing a stroller, wearing bulky or
very loose-fitting clothing or acces-
sories, or being in a unique posture
(such as raising hands).
– There is poor contrast of a person to the background, such as having
clothing color or pattern which is
similar to the background.
– For approximately 15 seconds after
starting the engine.
– If the vehicle ahead has a unique or unusual shape, extremely low or high
clearance heights, or unusual cargo
loading or is narrow (for example, a

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle. Failure to follow these recom-
mendations may result in shortened engine
life and reduced engine performance.
• Avoid driving for long periods at constant speed, either fast or slow, and do not run
the engine over 4,000 rpm.
• Do not accelerate at full throttle in any gear.
• Avoid quick starts.
• Avoid hard braking as much as possible.
• Do not tow a trailer for the first 500 miles (805 kilometers). Your engine, axle or other
parts could be damaged. 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 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 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.
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS
5-132Starting and driving

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 ef-
fectively 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. • Keep your engine tuned up.
• Follow the recommended scheduled
maintenance.
• Keep the tires inflated to the correct pres- sure. 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, see “Engine oil
and oil filter recommendations” (P. 10-6).
If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.
If the AWD error warning message is dis-
played, there may be a malfunction in the
Intelligent AWD system. Reduce vehicle
speed and have your vehicle checked as soon
as possible. It is recommended that you visit
an INFINITI retailer for this service.
