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” 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
surfaces and always drive carefully. .
Do not modify the vehicle’s suspension.
If suspension parts such as shock
absorbers, struts, springs, stabilizer
bars, bushings and wheels are not
INFINITI recommended for your vehicle
or are extremely deteriorated, the VDC
system may not operate properly. This
could adversely affect vehicle handling
performance, and the VDC warning light
may illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not INFINITI
recommended or are extremely deterio-
rated, the VDC system may not operate
properly and the VDC warning light
may illuminate.
. If engine control related parts are not
INFINITI recommended or are extremely
deteriorated, the VDC warning light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked corners,
the VDC system may not operate prop-
erly and the VDC warning light
may
illuminate. Do not drive on these types
of roads.
. When driving on an unstable surface
such as a turntable, ferry, elevator or ramp, the VDC warning light
may
illuminate. This is not a malfunction.
Restart the engine after driving onto a
stable surface.
. If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and
the VDC warning light
may illumi-
nate.
. The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.

Push the switch on to warn other drivers
when you must stop or park under
emergency conditions. All turn signal lights
will flash.
WARNING
.If stopping for an emergency, be sure to
move the vehicle well off the road.
. Do not use the hazard warning flashers
while moving on the highway unless
unusual circumstances force you to drive
so slowly that your vehicle might be-
come a hazard to other traffic. .
Turn signals do not work when the
hazard warning flasher lights are on.
The flasher can be actuated with the
ignition switch in any position.
Some state laws may prohibit the use of
the hazard warning flasher switch while
driving. In the event of a roadside emergency,
Roadside Assistance Service is available to
you. Please refer to your Warranty Informa-
tion Booklet (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada)

HAZARD WARNING FLASHER SWITCH
ROADSIDE ASSISTANCE PROGRAM

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 on 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 and “Tire Pressure Mon-
itoring System (TPMS)” in the“5. Starting
and driving” section.
WARNING
.If the low tire pressure warning light
illuminates 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 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. 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.
. Replacing tires with those not originally
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
