Warning light
When the system is not operating properly,
the chime sounds and the system warning
light (orange) will come on.
Action to take:
If the warning light comes on, park the
vehicle in a safe place. 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 at an INFINITI retailer.
PREVIEW FUNCTION (for Intelligent
Cruise Control (ICC) system
equipped model)
The Intelligent Cruise Control (ICC) system
with the preview function identifies the
need to apply emergency braking by
sensing the vehicle ahead in the same
lane and the distance to the vehicle ahead
and relative speed from it, it applies the
brake pre-pressure before the driver de-
presses the brake pedal and helps improve
brake response by reducing pedal free
play.

“Brake assist”later in
this section.
Starting and driving5-77

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.
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,
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.
When the 4L position is selected with the
4WD shift switch, the VDC system is
disabled and the VDC off indicator light
illuminates (for 4WD models).
See
“Vehicle Dynamic Control (VDC) warn-
ing light” in the“2. Instruments and
controls” section and “Vehicle Dynamic
Control (VDC) off indicator light” in the“2.
Instruments and controls” section.
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.
WARNING
. The VDC system is designed to help
improve driving stability but does not
prevent accidents due to abrupt steering
operation at high speeds or by careless
or dangerous driving techniques. Reduce
vehicle speed and be especially careful
when driving and cornering on slippery
Starting and driving5-115
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
.Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
. Push and hold the push-button ignition
switch for more than 2 seconds.TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears in the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.
If the vehicle is being driven with low tire
pressure, the TPMS will activate and warn
you of it by the low tire pressure warning
light. This system will activate only when
the vehicle is driven at speeds above 16
MPH (25 km/h). For more details, see
“Warning/indicator lights and audible re-
minders” in the“2. Instruments and
controls” section,“TIRE PRESSURE infor-
mation” in the“4. Monitor, climate, audio,
phone and voice recognition systems”
section and “Tire Pressure Monitoring
System (TPMS)” in the“5. Starting and
driving” section.
WARNING
.If the low tire pressure warning light
illuminates or LOW PRESSURE informa- tion is displayed on the monitor screen
while driving, avoid sudden 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 fail-
ure. 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. If you have a flat tire,
replace it with a spare tire as soon as
possible.
. 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.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.

Installing the spare tire
The full-size temporary use only spare tire
(if so equipped) is designed for emergency
use. (See specific instructions under the
heading“Wheels and tires” in the“8.
Maintenance and do-it-yourself” section.)
1. Clean any mud or dirt from the surface between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the
sequence as illustrated (
*1,*2,*3,
*4,*5,*6) until they are tight. 4. Lower the vehicle slowly until the tire
touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence as
illustrated. Lower the vehicle comple-
tely.
WARNING
. Incorrect wheel nuts or improperly tigh-
tened wheel nuts can cause the wheel to
become loose or come off. This could
cause an accident.
. Do not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
.As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque: 98 ft-lb (133 N·m)
The wheel nuts must be kept tigh-
tened to specification at all times. It

8-40Maintenance and do-it-yourself
.The original tires have built-in
tread wear indicators. When wear
indicators are visible, the tire(s)
should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. Improper service of the spare tire
may result in serious personal
injury. If it is necessary to repair
the spare tire, contact an INFINITI
retailer.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. (See
“Specifications” in the“9. Technical and
consumer information” section for recom-
mended types and sizes of tires and
wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of tires
of different brands, construction (bias,
bias-belted or radial), or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-tire
clearance, tire chain clearance, speed-
ometer calibration, headlight aim and
bumper height. Some of these effects
may lead to accidents and could result in
serious personal injury.
. For Two-Wheel Drive (2WD) models, if
your vehicle was originally equipped
with 4 tires that were the same size
and you are only replacing 2 of the 4
tires, install the new tires on the rear
axle. Placing new tires on the front axle may cause loss of vehicle control in
some driving conditions and cause an
accident and personal injury.
. If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimension.
Wheels of a different off-set could cause
premature tire wear, degrade vehicle
handling characteristics and/or interfer-
ence with the brake discs/drums. Such
interference can lead to decreased brak-
ing efficiency and/or early brake pad/
shoe wear. See “Wheels and tires” in the
“9. Technical and consumer information”
section of this manual for wheel off-set
dimensions.
. 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.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.
. Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
. Do not install a damaged or deformed

the vehicle may be reset to a“not ready
condition” . Before taking the I/M test,
check the vehicle’ s inspection/mainte-
nance test readiness condition. Place the
ignition switch in the ON position without
starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for
20 seconds and then blinks for 10
seconds, the I/M test condition is “not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”.
Contact an INFINITI retailer to set “ready
condition” or to prepare the vehicle for
testing. This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a
vehicle’s systems performed. The EDR is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or
less. The EDR in this vehicle is designed to
record such data as:
. How various systems in your vehicle
were operating;
. Whether or not the driver and passen-
ger safety belts were buckled/fastened;
. How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
. How fast the vehicle was traveling.
. Sounds are not recorded.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by your
vehicle only if a nontrivial crash situation
occurs; no data are recorded by the EDR
under normal driving conditions and no
personal data (e.g. name, gender, age and crash location) are recorded. However,
other parties, such as law enforcement,
could combine the EDR data with the type
of personally identifying data routinely
acquired during a crash investigation.
To read data recorded by an EDR, special
equipment is required and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer and INFINITI
retailer, other parties, such as law enforce-
ment, that have the special equipment, can
read the information if they have access to
the vehicle or the EDR. EDR data will only
be accessed with the consent of the vehicle
owner or lessee or as otherwise required or
permitted by law.
