BCI SYSTEM OPERATION
When the shift lever is in the R (Reverse)
position and the vehicle speed is less than
approximately 5 MPH (8 km/h), the BCI
system operates.
If the radar detects a vehicle approaching
from the side or the sonar detects close
stationary objects behind the vehicle, the
system gives visual and audible warnings. If
the driver does not apply the brakes, the
system automatically applies the brake for a
moment when the vehicle is moving back-
wards. After the automatic brake applica-
tion, the driver must depress the brake pedal
to maintain brake pressure. If the driver’s
foot is on the accelerator pedal, the system

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before insert-
ing it into the key hole or use the Intelligent
Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 32°F
(0°C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-5).
12-VOLT BATTERY
If the 12-volt battery is not fully charged
during extremely cold weather conditions,
the 12-volt battery fluid may freeze and
damage the 12-volt battery. To maintain
maximum efficiency, the 12-volt battery
should be checked regularly. For additional
information, see “12-volt battery” (P.8-13).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For details, see “Engine cooling
system” (P.8-5) and “Inverter cooling sys-
tem” (P.8-7).
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels. It is
recommended you consult an INFINITI re-
tailer for the tire type, size, speed rating and
availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
Tire chains may be used. For details, see
“Tire chains” (P.8-32).
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
.A scraper and stiff-bristled brush to
remove ice and snow from the windows
and wiper blades. .
A sturdy, flat board to be placed under
the jack to give it firm support.
. A shovel to dig the vehicle out of
snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
. Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip”
under these conditions. Try to avoid
driving on wet ice until the road is
salted or sanded.
. Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels will
lose even more traction.
. Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
. Allow greater following distances on
slippery roads.

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
.This vehicle has high voltage DC and
AC systems as well as a 12-volt
system. DC and AC high voltage is
very dangerous and can cause severe
burns and electric shock that may
result in serious injury or death.
. Never touch, disassemble, remove or
replace the high voltage parts, har-
nesses and their connectors. High
voltage cables are orange. Touching,
disassembling, removing or replacing
those parts and harnesses can cause
severe burns or electric shock that
may result in serious injury or death.
. Never try to remove the service plug
located in the trunk room. The service
plug is used only when the vehicle is
serviced by trained technicians wear-
ing personal protection equipment
and is part of the high voltage
system. Touching the service plug
can cause severe burns or electric shock that may result in serious injury
or death.
. The INFINITI Direct Response Hy-
brid
®System uses high voltage up to
408 volts. The system can be hot
while and after starting. Be careful of
both the high voltage and the high
