continuously covered with dirt, etc.
Action to take:
When the above conditions no longer exist,
the FEB with pedestrian detection system
will resume automatically.
NOTE:
When the inside of the windshield on
camera area is misted or frozen, it will take
a period of time to remove it after air
conditioner turns on. If dirt appears on this
area, it is recommended you visit an
INFINITI retailer.
Condition B
Under the following conditions, making it
impossible to detect a vehicle ahead, the
FEB with pedestrian detection system is
automatically turned off.
The FEB system warning light (orange)
will illuminate and the “Not Available: Front
Radar Blocked” warning message will ap-
pear in the vehicle information display.
. When the sensor area of the front
bumper is covered with dirt or is ob-
structed
Action to take:
If the FEB system warning light (orange)
comes on, stop the vehicle in a safe place,
place the shift lever in the P (Park) position and turn the engine off. Clean the radar
cover below the front bumper with a soft
cloth, and restart the engine. If the FEB
system warning light continues to illuminate,
have the FEB with pedestrian detection
system checked. It is recommended you visit
an INFINITI retailer for this service.

When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next
to long walls)
Action to take:
When the above conditions no longer exist,
the FEB with pedestrian detection system
will resume automatically.

SYSTEM MAINTENANCE
The radar sensoris located behind the
grille of the front bumper. The camerais
located on the upper side of the windshield.
To keep the FEB with pedestrian detection
system operating properly, be sure to ob-
serve the following:
. Always keep the sensor area of the front
bumper and windshield clean.
. Do not strike or damage the areas around
the sensors (ex. Bumper, windshield).
. Do not cover or attach stickers or similar
objects on the front bumper near the
sensor area. This could cause failure or
malfunction. .
Do not attach metallic objects near the
radar sensor area (brush guard, etc.).
This could cause failure or malfunction.
. Do not place reflective materials, such as
white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
detection capability.
. Do not alter, remove or paint the front
bumper. It is recommended you contact
an INFINITI retailer before customizing
or restoring the front bumper.

WARNING
Failure to follow the warnings and
instructions for proper use of the PFCW
system could result in serious injury or
death.
.The PFCW system helps warn the
driver before a collision but will not
avoid a collision. It is the driver’s
responsibility to stay alert, drive
safely and be in control of the vehicle
at all times.
The PFCW system can help alert the driver
when there is a sudden braking of a second
vehicle traveling in front of the vehicle ahead
in the same lane.

collision, the PFCW system will warn the
driver by blinking the vehicle ahead detection
indicator, and sounding an audible alert.

5-110Starting and driving
Follow 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 pedalapplication.
.Avoid rapid starts and stops..Use smooth, gentle accelerator andbrake 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 vehicle speeds.
.Below 40 MPH (64 km/h), it is moreefficient to open windows to cool the
vehicle due to reduced engine load.
.Above 40 MPH (64 km/h), it is moreefficient to use A/C to cool the
vehicle due to increased aerodynamic
drag.
.Recirculating the cool air in the cabinwhen the A/C is on reduces cooling
load. 4. Drive at economical speeds and dis-
tances.
.Observing the speed limit and notexceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.
.Maintaining a safe following distance
behind other vehicles reduces unne-
cessary braking.
.Safely monitoring traffic to anticipatechanges in speed permits reduced
braking and smooth acceleration
changes.
.Select a gear range suitable to roadconditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady speed.
.Cruise control is particularly effectivein 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 than30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal oper-ating temperature more quickly while
driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade whenever possi-
ble.
.When entering a hot vehicle, openingthe windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system.
FUEL EFFICIENT DRIVING TIPS

.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 the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-6).)
WARNING
. Do not attempt to raise two wheels
off the ground and shift the trans-
mission to any drive or reverse posi-
tion with the engine running. Doing
so may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage
or personal injury.
. Do not attempt to test a 4WD
equipped vehicle on a 2-wheel dy-
namometer or similar equipment even
if the other two wheels are raised off
the ground. Make sure you inform
test facility personnel that your ve-
hicle is equipped with 4WD before it
is placed on a dynamometer. Using
the wrong test equipment may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury.
CAUTION
.Do not drive the vehicle in the 4HI or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces in 4HI or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the Four-Wheel Drive (4WD)
warning light turns on when driving
on dry hard surface roads:
— in the 4HI position, shift the 4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmission
lever to the N (Neutral) position
with the brake pedal depressed
and shift the 4WD shift switch to
AUTO.
If the 4WD warning light is still on
after the above operation, have
your vehicle checked. It is recom-
mended you visit an INFINITI
retailer for this service.
. The transfer case may be damaged if
you continue driving with the 4WD
warning light blinking.
See “On-pavement and off-road driving
precautions” (P.5-8) for other precautions
for offroad driving.
