FCW SYSTEM LIMITATIONS

WARNING

Listed below are the system limitations of
the FCW system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.

.

The system will not detect the following
objects:

— Pedestrians, animals or obstacles in

the roadway

— Oncoming vehicles in the same lane

.

The system will not detect another
vehicle under the following conditions:

— When the sensor gets dirty and it is

impossible to detect the distance
from the vehicle ahead.

— When driving into a strong light (for

example, sunlight)

.

The sensor generally detects the signals
returned from the reflectors on a vehicle
ahead. Therefore, the system may not
function properly under the following
conditions:

— When the reflectors of the vehicle

ahead are positioned high or close to
each other (including a small vehicle
such as motorcycles).

— When the sensor gets dirty or it is

impossible to detect the distance
from the vehicle ahead.

— When the reflectors on the vehicle

ahead are missing, damaged or
covered.

— When the reflectors of the vehicle

ahead are covered with dirt, snow or
road spray.

— When visibility is low (such as rain,

fog, snow, etc.).

— When snow or road spray from

traveling vehicles is splashed.

— When dense exhaust or other smoke

(black smoke) from vehicles reduces
the visibility of the sensor.

— When excessively heavy baggage is

loaded in the rear seat or the luggage
room of your vehicle.

— When abruptly accelerating or de-

celerating.

— On a steep downhill slope or on

roads with sharp curves.

— When there is a highly reflective

object near the vehicle ahead (for
example, being very close to another
vehicle, signboard, etc.)

— When you are towing a trailer.

.

Depending on certain road conditions
(curved or beginning of a curve), vehicle
conditions (steering position or vehicle
position), or the preceding vehicle’s
conditions (position in lane, etc.), the
system may not function properly. The
system may detect highly reflective
objects such as reflectors, signs, white
markers, and other stationary objects on
the road or near the traveling lane and
provide unnecessary warning.

.

The system may not function in offset
conditions.

.

The system may not function when the
distance to the vehicle ahead is extre-
mely close.

.

The system is designed to automatically
check the sensor’s functionality. If the
sensor is covered with ice, a transparent
or translucent plastic bag, etc., the

system may not detect them. In these
instances the system may not be able to
warn the driver properly. Be sure to
check and clean the sensor regularly.

.

Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.

.

A sudden appearance of a vehicle in front
(for example, it abruptly cuts in) may not
be detected and the system may not
warn the driver soon enough.

Starting and driving

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 recommendations
may result in shortened engine life and
reduced engine performance.

.

Avoid driving for long periods at con-

stant speed, either fast or slow. 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 possi-

ble.

.

Do not tow a trailer for the first 500

miles (805 km).

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

pedal application.

.

Avoid rapid starts and stops.

.

Use smooth, gentle accelerator and
brake application whenever possi-
ble.

.

Maintain constant speed while com-
muting and coast whenever possi-
ble.

2. Maintain constant speed.

.

Look ahead to try and anticipate and
minimize stops.

.

Synchronizing your speed with traf-
fic lights allows you to reduce your
number of stops.

.

Maintaining a steady speed can
minimize red light stops and im-
prove 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 aerody-

namic 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
exceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.

.

Maintaining a safe following dis-
tance behind other vehicles reduces
unnecessary braking.

.

Safely monitoring traffic to antici-
pate changes in speed permits
reduced braking and smooth accel-
eration 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 effec-
tive 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 cruis-
ing 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
effectively circulate the engine oil
before driving.

.

Your vehicle will reach its ideal
operating temperature more quickly
while driving versus idling.

10.Keeping your vehicle cool.

.

Park your vehicle in a covered
parking area or in the shade when-
ever possible.

.

When entering a hot vehicle, open-
ing the windows will help to reduce
the inside temperature faster, result-
ing 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 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
recommendation” (P.10-6).)

The AWD warning light is located in the
meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON
position. It turns off soon after the engine
is started.
If any malfunction occurs in the AWD

system while the engine is running, the
warning light will come on.
The warning light may blink rapidly (about
twice per second) while trying to free a
stuck vehicle due to high power train oil
temperature. The driving mode may change
to two-wheel drive. If the warning light
blinks rapidly during operation, stop the
vehicle with the engine idling in a safe
place immediately. Then if the light goes
off after a while, you can continue driving.
A large difference between the diameters
of front and rear wheels will make the
warning light blink slowly (about once per
two seconds). Pull off the road in a safe
area, and idle the engine. Check that all tire
sizes are the same, tire pressure is correct
and tires are not worn.
If the warning light is blinking after the
above operation, have your vehicle
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for
this service.

WARNING

.

For AWD equipped vehicles, do not
attempt to raise two wheels off the

ground and shift the transmission to
any drive or reverse position 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 an AWD equipped
vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing) or similar
equipment even if the other two wheels
are raised off the ground. Make sure you
inform the test facility personnel that
your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.

CAUTION

.

Do not operate the engine on a free roller
when any of the wheels are raised.

.

If the warning light comes on while
driving there may be a malfunction in the

WARNING

.

Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.

.

Never leave the engine running while the
vehicle is unattended.

.

Do not leave children unattended inside
the vehicle. They could unknowingly
activate switches or controls. Unat-
tended children could become involved
in serious accidents.

.

To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or death
to people and pets.

.

Safe parking procedures require that
both the parking brake be applied and
the transmission be placed in the P

WARNING

If the engine is not running or is turned off
while driving, the power assist for the
steering will not work. Steering will be
harder to operate.

The power assisted steering uses a hy-
draulic pump, driven by the engine, to
assist steering.
If the engine stops or the drive belt breaks,
you will still have control of the vehicle.
However, much greater steering effort is
needed, especially in sharp turns and at
low speeds.
