detect vehicles traveling ahead. The sensor
generally detects the signals returned from
the vehicle ahead. Therefore, if the sensor
cannot detect the reflection from the
vehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which
the sensor cannot detect the signals:
.When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When excessively heavy baggage is
loaded in the rear seat or the trunk of
your vehicle
The ICC system is designed to automati-
cally check the sensor’s operation within
the limitations of the system. When the
sensor area of the front bumper is covered
with dirt or is obstructed, the system will
automatically be canceled. If the sensor
area is covered with ice, a transparent or
translucent vinyl bag, etc., the ICC system
may not detect them. In these instances,
the vehicle-to-vehicle distance control
mode may not cancel and may not be able
to maintain the selected following distance
from the vehicle ahead. Be sure to check
and clean the sensor area regularly. The vehicle-to-vehicle distance control
mode is designed to maintain a selected
distance and reduce the speed to match
the slower vehicle ahead; the system will
decelerate the vehicle as necessary and if
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill. How-
ever, the ICC system can only apply up to
approximately 40% of the vehicles total
braking power. This system should only be
used when traffic conditions allow vehicle
speeds to remain fairly constant or when
vehicle speeds change gradually. If a
vehicle moves into the traveling lane ahead
or if a vehicle traveling ahead rapidly
decelerates, the distance between vehicles
may become closer because the ICC system
cannot decelerate the vehicle quickly en-
ough. If this occurs, the ICC system will
sound a warning chime and blink the
system display to notify the driver to take
necessary action.
The system will cancel and a warning
chime will sound if the speed is below
approximately 15 MPH (24 km/h) and a
vehicle is not detected ahead. The system
will also disengage when the vehicle goes
above the maximum set speed.
See
“Approach warning” (P.5-71).The following items are controlled in the
vehicle-to-vehicle distance control mode:
.
When there are no vehicles traveling
ahead, the vehicle-to-vehicle distance
control mode maintains the speed set
by the driver. The set speed range is
between approximately 20 and 90 MPH
(32 and 144 km/h).
. When there is a vehicle traveling ahead,
the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by driver, from the
vehicle ahead. The adjusting speed
range is up to the set speed. If the
vehicle ahead comes to a stop, the
vehicle decelerates to a standstill with-
in the limitations of the system. The
system will cancel once it judges a
standstill with a warning chime.
. When the vehicle traveling ahead has
moved out from its lane of travel, the
vehicle-to-vehicle distance control
mode accelerates and maintains vehi-
cle speed up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles

Before attempting to jump start the vehi-
cle, make sure the fuel tank is not empty
and the correct starting procedure is
followed. See“Starting the INFINITI Direct
Response Hybrid
®System” (P.5-14). Do
not drive the vehicle on battery power only
if the fuel tank is empty. The Lithium ion
(Li-ion) battery will become discharged and
the INFINITI Direct Response Hybrid
®Sys-
tem will turn off.
CONFIRM BATTERY IS DISCHARGED
If any of the following conditions occurs,
the 12-volt battery might discharged:
. The instrument cluster and/or head-
lights are not normal brightness.
. Audio accessories cannot be turned on.
. The hybrid system does not become
READY to drive mode.
. The ignition switch cannot be placed in
the ON position.
Check the following if you notice above
conditions.
1. Check that the 12-volt battery terminals are tight and clean. See “12-volt
battery” (P.8-17). The 12-volt battery
is located on the left hand side of the
trunk behind an access panel. If the 12-
volt battery terminals are loose, contact your INFINITI retailer.
2. If the 12-volt battery terminals are tight and clean, try to jump start the vehicle.
See “Jump starting” (P.6-5).
If the hybrid system still does not start,
contact an INFINITI retailer. To start your INFINITI Direct Response
Hybrid
®System with a booster battery,
the instructions and precautions below
must be followed.
Jump starting provides power to the 12 volt
system to allow the electrical systems to
operate. The electrical systems must be
operating to allow the Lithium ion (Li-ion)
battery to be charged. Jump starting does
not charge the Li-ion battery.
WARNING
. If done incorrectly, jump starting can
lead to a 12-volt battery explosion,
resulting in severe injury or death. It
could also damage your vehicle.
. Explosive hydrogen gas is always pre-
sent in the vicinity of the 12-volt battery.
Make sure that the vent tube is
mounted.
. Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a
corrosive sulfuric acid solution which
can cause severe burns. If the fluid
should come into contact with anything,
immediately flush the contacted area
with water.

Occasionally remove loose dust from the
interior trim, plastic parts and seats using
a vacuum cleaner or soft bristled brush.
Wipe the vinyl and leather surfaces with a
clean, soft cloth dampened in mild soap
solution, then wipe clean with a dry soft
cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather.
Before using any fabric protector, read the
manufacturer’s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water, to
clean the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classification
sensors. This can also affect the operation
of the air bag system and result in serious
personal injury.
CAUTION
. Never use benzine, thinner, or any
similar material.
. For cleaning, use a soft cloth, dampened
with water. Never use a rough cloth,
alcohol, benzine, thinner or any kind of
solvent or paper towel with a chemical
cleaning agent. They will scratch or
cause discoloration to the lens.

It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see“Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir. When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
