vehicle is on a lane marker when
another vehicle enters the detection
zone. In this case only the BSW system
operates.
. BSI braking will not operate or will stop
operating and only a warning chime
will sound under the following condi-
tions.
— When the brake pedal is depressed.
— When the accelerator pedal is de-
pressed while brake control assist
is provided. —
When steering quickly
— When the ICC, DCA, FCW or IBA
warnings sound.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.
BSW/BSI temporarily not available
. Under the following conditions, the BSI
system will be turned off automatically,
a beep will sound and the BSI ON
indicator light (green) will blink. The
BSW system is still available, but the
BSI system will not be available until
the conditions no longer exist.
— When the VDC system (except TCS
function) or ABS operates.
— When the VDC system is turned off.
— When the drive mode select switch
is turned to the SNOW mode.
Action to take:
Turn off the BSI system and turn it on again
when the above conditions no longer exist.
. Under the following conditions, the
BSW and BSI systems will be turned
off automatically, a beep will sound
and the BSW/BSI system warning light (orange) will blink. The BSW and BSI
systems are not available until the
conditions no longer exist.
—
When the camera detects that the
interior temperature is high (over
approximately 1048F (408C)).
— When radar blockage is detected.
The radar sensors may be blocked by
temporary ambient conditions such as
splashing water, mist or fog. The blocked
condition may also be caused by objects
such as ice, frost or dirt obstructing the
radar sensors.
Action to take:
When the above conditions no longer exist,
the BSW system will resume automatically.
For the BSI system, turn it off and turn it on
again. If the BSW/BSI warning light (or-
ange) continues to blink even after the BSI
system is turned on again, stop the vehicle
in a safe location and turn the engine off.
Check for and remove objects obscuring
the radar sensors on the rear bumper, and
restart the engine.
If the warning light (orange) continues to
blink, have the BSW/BSI systems checked
by an INFINITI retailer.

ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remember
that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front of
you. Ultimately, the driver is responsible
for safety.
. Tire type and condition may also affect
braking effectiveness.
—When replacing tires, install the
specified size of tires on all four
wheels.
—When installing a spare tire, make
sure that it is the proper size and
type as specified on the Tire and
Loading Information label. See “Tireand loading information label”
in the
“9. Technical and consumer informa-
tion” section of this manual.
—For detailed information, see
“Wheels and tires” in the“8. Main-
tenance and do-it-yourself” section
of this manual.
The Anti-lock Braking System (ABS) con-
trols the brakes so the wheels do not lock
during hard braking or when braking on
slippery surfaces. The system detects the
rotation speed at each wheel and varies
the brake fluid pressure to prevent each
wheel from locking and sliding. By pre-
venting each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels
from locking up. Steer the vehicle to avoid
obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, elec-
tric pumps, hydraulic solenoids and a
computer. The computer has a built-in
diagnostic feature that tests the system
each time you start the engine and move
the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsa-
tion in the brake pedal. This is normal and
does not indicate a malfunction. If the
computer senses a malfunction, it switches
the ABS off and illuminates the ABS
warning light on the instrument panel.
The brake system then operates normally,
but without anti-lock assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked by an INFINITI retailer.
Starting and driving5-99

5-100Starting and driving
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic
pressure. This action is similar to pumping
the brakes very quickly. You may feel a
pulsation in the brake pedal and hear a
noise from under the hood or feel a
vibration from the actuator when it is
operating. This is normal and indicates
that the ABS is operating properly. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver
inputs and vehicle motion. Under certain
driving conditions, the VDC system helps
to perform the following functions.
.
Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip based
on vehicle speed (traction control func-
tion).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due
to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel flashes so note the following:
.
The road may be slippery or the system
may determine some action is required
to help keep the vehicle on the steered
path.
. You may feel a pulsation in the brake
pedal and hear a noise or vibration
from under the hood. This is normal
and indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
See “Vehicle Dynamic Control (VDC) warn-
ing light” in the“2. Instruments and
controls” section.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is
off. When the VDC switch is used to turn off
the system, the VDC system still operates
to prevent one drive wheel from slipping by
transferring power to a non slipping drive
wheel. The VDC warning light
flashes if
this occurs. All other VDC functions are off,
except for rise-up and build-up and brake
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

The 4 Wheel Active Steer (4WAS) system is
an electronically controlled four-wheel
steering system.
Depending on the vehicle speed and
steering angle, the angles of the front
and rear wheels are adjusted by the 4WAS
system to help improve driving perfor-
mance.
If a malfunction occurs in the system, the
4WAS function will stop but the ordinary
two-wheel steering system will operate
normally. The“4WAS”warning light will
illuminate. If the light illuminates while you
are driving, contact an INFINITI retailer for
repair.
The steering wheel may be slightly turned
even when driving on a straight road due to
a protection mechanism for the 4WAS
system. This is not a malfunction. The
steering wheel will return to the normal
position after the protection mechanism
deactivates.
The protection mechanism activates under
the following conditions:
. The steering wheel is operated forcibly
when it is hard to operate or the tires
are blocked by obstacles.
. The steering wheel is continuously
operated when the vehicle is parked or being driven at extremely low speed.
. The steering wheel is forcibly turned
beyond its operation limits.
. The battery voltage is reduced.
Repeated steering maneuvers that may
activate the protection mechanism will
damage the 4WAS system.
WARNING
The 4WAS system, although a sophisticated
device, cannot prevent accidents resulting
from careless or dangerous driving tech-
niques. Ultimately the responsibility for
safety of self and others rests in the hands
of the driver. Therefore only through atten-
tive and careful driving methods can the
4WAS system be fully appreciated and
safety optimized.
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
inserting 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 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” in the
“8. Maintenance and do-it-yourself” sec-
tion.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”in
the “8. Maintenance and do-it-yourself”
section.

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system”in the“8. Main-
tenance and do-it-yourself” section.
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.
Consult an INFINITI retailer 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 prohi-
bit 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”
in the“8. Maintenance and
do-it-yourself” section of this manual.
For all-wheel drive
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.
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 (328F, 0 8C 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 cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting 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 pavement.
. Allow greater following distances on
slippery roads.
. Watch for slippery spots (glare ice).
These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.

.Do not use the cruise control on slippery
roads.
. Snow can trap dangerous exhaust gases
under your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist in
cold temperature starting.
The engine block heater should be used
when the outside temperature is 208 F
(−78C) or lower.
To use the engine block heater
1. Turn the engine off.
2. Open the hood and unwrap the engine
block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2 - 4 hours, depending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
WARNING
. Do not use your engine block heater with
an ungrounded electrical system or a 2-
pronged adapter. You can be seriously
injured by an electrical shock if you use
an ungrounded connection.
. Disconnect and properly store the en-
gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury.
. Use a heavy-duty 3-wire, 3-pronged
extension cord rated for at least 10A.
Plug the extension cord into a Ground
Fault Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the proper
extension cord or a grounded outlet can
result in a fire or electrical shock and
cause serious personal injury.

WARNING
.Never get under the vehicle while it is
supported only by the jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Use only the jack provided with your
vehicle to lift the vehicle. Do not use the
jack provided with your vehicle on other
vehicles. The jack is designed for lifting
only your vehicle during a tire change.
. Use the correct jack-up points. Never use
any other part of the vehicle for jack
support.
. Never jack up the vehicle more than
necessary.
. Never use blocks on or under the jack.
. Do not start or run the engine while
vehicle is on the jack, as it may cause
the vehicle to move. This is especially
true for vehicles with limited slip differ-
entials.
. Do not allow passengers to stay in the
vehicle while it is on the jack.
Carefully read the caution label attached to
the jack body and the following instruc-
tions.
