mWARNING
Failure to follow the warnings and
instructions for proper use of the BCI
system could result in serious injury or
death.
.
The BCI system is not a replacement
for proper driving procedure, is not
designed to prevent contact with
vehicles or objects and does not
provide full brake power. When back-
ing out of parking spaces, always use
the inside and rear mirrors and turn
and look in the direction you will
move. Never rely solely on the BCI
system.
. There is a limitation to the detection
capability of the radar or the sonar.
Using the BCI system under some
road, ground, traffic or weather con-
ditions could lead to improper system
operation. Always rely on your own
operation to avoid accidents.
The BCI system can help alert the driver of
an approaching vehicle or objects behind the
vehicle when the driver is backing out of a
parking space.

Vehicle-to-vehicle distance control
mode limitations
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. The system is primarily intended for
use on straight, dry, open roads with
light traffic. It is not advisable to use
the system in city traffic or con-
gested areas.
. This system will not adapt automati-
cally to road conditions. This system
should be used in evenly flowing
traffic. Do not use the system on
roads with sharp curves, or on icy
roads, in heavy rain or in fog.
. As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absent-minded driving, or over- come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
. If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel once it judges
that the vehicle has come to a
standstill and sound a warning chime.
To prevent the vehicle from moving,
the driver must depress the brake
pedal.
. Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The vehicle-to-vehicle
distance control mode of the ICC
system may not be able to maintain
the selected distance between vehi-
cles (following distance) or selected
vehicle speed under some circum-
stances.
. The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, never use the ICC system
under the following conditions:

3. Push, then quickly release the SET/COAST (-) switch. Each time you do this,
the set speed will decrease by about 1
MPH (1.6 km/h).
To resume the preset speed, push and
release the RESUME/ACCELERATE (+)
switch. The vehicle will resume the last set
cruising speed when the vehicle speed is over
25 MPH (40 km/h).
System temporarily unavailable
A chime sounds under the following condi-
tions and the control is automatically can-
celed.
. When the vehicle slows down more than
8 MPH (13 km/h) below the set speed
. When the shift lever is not in the D (Drive)
or manual shift mode
. When the parking brake is applied.
. When the VDC operates (including the
traction control system)
. When a wheel slips
JVS0306X
Warning
When the system is not operating properly,
the chime sounds and the color of the cruise
indicator will change to orange.
Action to take:
If the color of the cruise indicator changes to
orange, stop the vehicle in a safe place and
place the shift lever in the P (Park) position.
Turn the engine off, restart the engine,
resume driving and then perform the setting
again.
If it is not possible to set or the indicator
stays on, it may indicate that the system is
malfunctioning. Although the vehicle is still
driveable under normal conditions, have the vehicle checked. It is recommended you visit
an INFINITI retailer for this service.

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 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.
3. To help prevent the vehicle from rolling into the street when parked on a sloping
drive way, it is a good practice to turn the
wheels as illustrated.
.HEADED DOWNHILL WITH CURB:
Turn the wheels into the curb and
move the vehicle forward until the
curb side wheel gently touches the
curb.
.HEADED UPHILL WITH CURB:
Turn the wheels away from the curb
and move the vehicle back until the
curb side wheel gently touches the
curb.
.HEADED UPHILL OR DOWNHILL,
NO CURB:
Turn the wheels toward the side of
the road so the vehicle will move away

a straight road for a period of time.
. After the engine is started, the steering
wheel may move if the steering wheel
was turned to the fully locked position
while the ignition switch was in the OFF
position.
. After the vehicle is tested on the 4-wheel
dynamometer, the steering wheel may
turn slightly even when driving on a
straight road. To return the steering
wheel to the normal position, drive the
vehicle on a straight road for a period of
time.
You may hear a noise under the following
conditions. However, this is not a malfunc-
tion.
. When the engine is started or stopped.
. When the steering wheel is turned in the
full lock position.BRAKING PRECAUTIONS
The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on
the brake pedal will be required to stop the
vehicle and the stopping distance will be
longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will cause overheating of
the brakes, wearing out the brake and pads
faster and reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance and
could result in loss of vehicle control.
WARNING
. While driving on a slippery surface,
be careful when braking, accelerating or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.
. If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be longer
and the vehicle may pull to one side during
braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake pedal
to heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced, in
order to assure the best braking perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended you visit
BRAKE SYSTEM

6-4In case of emergency
is recommended you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
. Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
RUN-FLAT TIRES (if so equipped)
Run-flat tires are those tires that can be
used temporarily if they are punctured. See
“Run-flat tires” (P.8-39).
Also, refer to “Important Tire Safety Infor-
mation” (US) or “Tire Safety Information”
(Canada) in the INFINITI Warranty Informa-
tion Booklet.
WARNING
.Although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling stabi-
lity is reduced, which could lead to an
accident and personal injury. Also,
driving a long distance at high speeds
may damage the tires. .
Do not drive at speeds above 50
MPH (80 km/h) and do not drive
more than approximately 93 miles
(150 km) with a punctured run-flat
tire. The actual distance the vehicle
can be driven on a flat tire depends on
outside temperature, vehicle load,
road conditions and other factors.
. Drive safely at reduced speeds. Avoid
hard cornering or braking, which may
cause you to lose control of the
vehicle.
. If you detect any unusual sounds or
vibrations while driving with a punc-
tured run-flat tire, pull off the road
to a safe location and stop the vehicle
as soon as possible. The tire may be
seriously damaged and need to be
replaced.
CAUTION
.Never install tire chains on a punctu-
red run-flat tire, as this could damage
your vehicle.
. Avoid driving over any projection or
pothole, as the clearance between
the vehicle and the ground is smaller
than normal. .
Do not enter an automated car wash
with a punctured run-flat tire.
. It is recommended you have the
punctured tire inspected by an
INFINITI retailer or other authorized
repair shop. Replace the tire as soon
as possible if the tire is seriously
damaged.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
in this section to replace the tire with a spare
tire (if so equipped). For the vehicles with
run-flat tires, you can continue driving to a
safe location even if they are punctured. (See
“Run-flat tires” (P.6-4) and “Run-flat tires”
(P.8-39).)
This section also contains the information
about the vehicle jack-up procedures.
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to the
P (Park) position.
4. Turn off the engine.

5. Raise the hood to warn other traffic, andto signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
.Make sure the parking brake is
securely applied and the automatic
transmission into P (Park).
. Never change tires when the vehicle
is on a slope, ice or slippery areas.
This is hazardous.
. Never change tires if oncoming traf-
fic is close to your vehicle. Wait for
professional road assistance.
MCE0001A
Blocking wheels
Place suitable blocksat both the front and
back of the wheel diagonally opposite the
