WARNING
.Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use.
. If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
after adjusting the tire pressure, a
tire may be flat or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a spare tire (if so equipped) as soon as possible. If no
tire is flat and all tires are properly
inflated, it is recommended you con-
sult an INFINITI retailer.
. For models with run-flat tires,
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.
— If you detect any unusual sounds or vibrations while driving with a
punctured run-flat tire, pull off
the road to a safe location and
stop the vehicle as soon as possi-
ble. The tire may be seriously
damaged and need to be replaced.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
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.
CAUTION
.The TPMS may not function properly
when the wheels are equipped with
tire chains or the wheels are buried in
snow.
. Do not place metalized film or any
metal parts (antenna, etc.) on the
windows. This may cause poor recep-
tion of the signals from the tire
pressure sensors, and the TPMS will
not function properly.

CRUISE CONTROL OPERATIONS
The cruise indicator and the set vehicle
speed are displayed in the vehicle informa-
tion display. The cruise indicator indicates
the status of the cruise control system by the
color.
The cruise control allows driving at a speed
between 25 to 90 MPH (40 to 144 km/h)
without keeping your foot on the accelerator
pedal.
To turn on the cruise control,push the
MAIN switch on. The cruise indicator (white)
will come on. To set cruising speed,
accelerate your
vehicle to the desired speed, push the SET/
COAST (-) switch and release it. (The cruise
indicator (green) will illuminate.) Take your
foot off the accelerator pedal. Your vehicle
will maintain the set speed.
. To pass another vehicle, depress the
accelerator pedal. When you release the
pedal, the vehicle will return to the
previously set speed.
. The vehicle may not maintain the set
speed on winding or hilly roads. If this
happens, drive without the cruise con-
trol.
To cancel the preset speed, follow any of
these methods:
1. Push the CANCEL switch.
2. Tap the brake pedal.
3. Turn the MAIN switch off.
After any of the above operations is per-
formed, the color of the cruise indicator will
change from green to white.
. If you depress the brake pedal while
pushing the RESUME/ACCELERATE
(+) or SET/COAST (-) switch and reset
at the cruising speed, the cruise control
will disengage. Turn the MAIN switch off
once and then turn it on again.
. The cruise control will automatically
cancel if the vehicle slows more than 8

MPH (13 km/h) below the set speed.
. If you move the shift lever to N (Neutral)
position, the cruise control will be can-
celed.
To reset at a faster cruising speed, use one
of the following methods:
. Depress the accelerator pedal. When the
vehicle attains the desired speed, push
and release the SET/COAST (-) switch.
. Push and hold the RESUME/ACCELER-
ATE (+) switch. When the vehicle attains
the speed you desire, release the switch.
. Push, then quickly release the RESUME/
ACCELERATE (+) switch. Each time you
do this, the set speed will increase by
about 1 MPH (1.6 km/h).
To reset at a slower cruising speed, use one
of the following methods:
. Lightly tap the brake pedal. When the
vehicle attains the desired speed, push
the SET/COAST (-) switch and release it.
. Push and hold the SET/COAST (-)
switch. Release the switch when the
vehicle slows down to the desired speed.
. 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).WARNING
Failure to follow the warnings and
instructions for proper use of the ICC
system could result in serious injury or
death.
.
ICC is not a collision avoidance or
warning device. For highway use only
and it is not intended for congested
areas or city driving. Failure to apply
the brakes could result in an accident.
. Always observe posted speed limits
and do not set the speed over them.
. Always drive carefully and atten-
tively when using either cruise con-
trol mode. Read and understand the
Owner’s Manual thoroughly before
using the cruise control. To avoid
serious injury or death, do not rely
on the system to prevent accidents or
to control the vehicle’s speed in
emergency situations. Do not use
cruise control except in appropriate
road and traffic conditions.
. In the conventional (fixed speed)
cruise control mode, a warning chime
will not sound to warn you if you are
too close to the vehicle ahead. Pay
special attention to the distance
between your vehicle and the vehicle
Starting and driving5-71

5-128Starting and 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 out-
put to reduce drive wheel slip based on
vehicle speed (traction control function).
. 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 conditions).
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” (P.2-17).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system automa-
tically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator light
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 brake force distribution, and the
VDC warning light
will not flash. The
VDC system is automatically reset to on
when the ignition switch is placed in the off
position then back to the on position.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-17) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-16).
The computer has a built-in diagnostic feature that tests the system each time you
start the engine and move the vehicle
forward or in reverse at a slow speed. When
the self-test occurs, you may hear a “clunk”
noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indication
of a malfunction.
VDC operation is reduced when the INFINITI
Drive Mode Selector is used to select the
SPORT+ mode (if so equipped). The VDC
system may not operate in the same circum-
stances when compared to operation in the
standard mode. To help prevent accidents
drive carefully, avoid careless or dangerous
driving techniques and be especially careful
when driving and cornering on slippery
surfaces.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the four wheels depending
on the radius of the turn.
WARNING
.
The VDC system is designed to help
the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
