for the PFCW system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. The PFCW system cannot detect all

vehicles under all conditions.

. The radar sensor does not detect the

following objects:

— Pedestrians, animals or obstacles

in the roadway

— Oncoming vehicles

— Crossing vehicles

. (Illustration A) The PFCW system

does not function when a vehicle
ahead is a narrow vehicle, such as a
motorcycle.

. The radar sensor may not detect a

vehicle ahead in the following condi-
tions:

— Snow or heavy rain

— Dirt, ice, snow or other material

covering the radar sensor

— Interference by other radar

sources

— Snow or road spray from travel-

ling vehicles.

— Driving in a tunnel

— (Illustration B) When the vehicle

ahead is being towed.

— (Illustration C) When the distance

to the vehicle ahead is too close,
the beam of the radar sensor is
obstructed.

— (Illustration D) When driving on a

steep downhill slope or roads with
sharp curves.

. The system is designed to automati-

cally check the sensor’s functionality,
within certain limitations. The system
may not detect some forms of ob-
struction of the sensor area such as
ice, snow, stickers, for example. In
these cases, the system may not be
able to warn the driver properly. Be
sure that you check, clean and clear
the sensor area regularly.

may not be heard.

SSD0253

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar
sensor may detect vehicles in a different
lane, or may temporarily not detect a vehicle
traveling ahead. This may cause the PFCW
system to work inappropriately.

The detection of vehicles may also be
affected by vehicle operation (steering man-
euver or traveling position in the lane, etc.) or
vehicle condition. If this occurs, the system
may warn you by blinking the system
indicator and sounding the chime unexpect-
edly. You will have to manually control the
proper distance away from the vehicle
traveling ahead.

CAUTION

During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and en-
sure 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 constant

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 possible.

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 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 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.

FUEL EFFICIENT DRIVING TIPS

5-122

Starting and driving

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 distance

behind other vehicles reduces unne-
cessary 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
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 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, 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 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).)

INCREASING FUEL ECONOMY

If any malfunction occurs in the Intelligent
All-Wheel Drive (AWD) system while the
INFINITI Direct Response Hybrid

®

System is

running, warning messages appear in the
vehicle information display.

JVS0228M

If the “AWD Error” warning

appears, there

may be a malfunction in the Intelligent AWD
system. Reduce vehicle speed and have the
system checked as soon as possible. It is
recommended you visit an INFINITI retailer
for this service.

The “AWD High Temp.” (high temperature)
warning

may appear while trying to free a

stuck vehicle due to increased oil tempera-
ture. The driving mode may change to Two-
Wheel Drive (2WD). If this warning is
displayed, stop the vehicle with the hybrid
system idling, as soon as it is safe to do so.
Then if the warning turns off, you can
continue driving.

The “Tire Size Incorrect” warning

may

appear if there is a large difference between
the diameters of front and rear wheels. Pull
off the road in a safe area, with the hybrid
system idling. Check that all tire sizes are the
same, that the tire pressure is correct and
that the tires are not excessively worn.

If any warning message continues to be
displayed, have your vehicle checked as soon
as possible. It is recommended 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
hybrid system running. Doing so may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.

Starting and driving

. Do not attempt to test an AWD

equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing) or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with
AWD before it is placed on a dynam-
ometer. Using the wrong test equip-
ment may result in drivetrain damage
or unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.

CAUTION

. Do not operate the hybrid system on

a free roller when any of the wheels
are raised.

. If the “AWD Error” warning appears

while driving there may be a mal-
function in the AWD system. Reduce
the vehicle speed and have your
vehicle checked as soon as possible.
It is recommended you visit an
INFINITI retailer for this service.

. If the “AWD Error” warning remains

on after the above operation, have

System in the READY

to drive mode while the vehicle is
unattended.

. Do not leave children unattended

inside the vehicle. They could un-
knowingly activate switches or con-
trols. Unattended 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
assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly
become high enough to cause a sig-
nificant risk of injury or death to
people and pets.

. Safe parking procedures require that

both the parking brake be applied
and the transmission placed into P

(Park). Failure to do so could cause
the vehicle to move unexpectedly or
roll away and result in an accident.

. Make sure the automatic transmis-

sion shift lever has been pushed as far
forward as it can go and cannot be
moved without depressing the foot
brake pedal.

1. Firmly apply the parking brake.

2. Move the shift lever to the P (Park)

position.
