WARNING
.If the light does not illuminate with
the ignition switch pushed ON, have
the vehicle checked as soon as possi-
ble. It is recommended you visit an
INFINITI retailer for this service.
. If the 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 pres-
sure 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 pres-
sure, a tire may be flat or the TPMS
may be malfunctioning. If you have a
flat tire, replace it with a spare tire as
soon as possible. If no tire is flat and
all tires are properly inflated, have the vehicle checked. It is recom-
mended you visit an INFINITI retailer
for this service.
. 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 the 1 minute.
Have your tires replaced and/or
TPMS system reset as soon as pos-
sible. 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.
CAUTION
.The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
. If the vehicle is being driven at speeds
of less than 16 MPH (25 km/h), the
TPMS may not operate correctly.
. Be sure to install the specified size of
tires to the four wheels correctly.

bag systems and/or pretensioner seat belt
are operational.
If any of the following conditions occur, the
supplemental front air bag, supplemental
side air bag, supplemental curtain side-
impact air bag and pretensioner seat belt
needs servicing.

tensioner seat belt may not function
properly.
For additional information, see “Supplemen-
tal restraint system” (P.1-38).WARNING
If the supplemental air bag warning light
is on, it could mean that the front air
bag, side air bag, curtain air bag systems
and/or pretensioner seat belt will not
operate in an accident. To help avoid
injury to yourself or others, have your
vehicle checked. It is recommended you
visit an INFINITI retailer for this service.
Vehicle Dynamic Control
(VDC) warning light
When the ignition switch is in the ON
position, the Vehicle Dynamic Control
(VDC) warning light illuminates and then turns off.
The light will blink when the VDC system or
the traction control system is operating, thus
alerting the driver that the vehicle is nearing
its traction limits. The road surface may be
slippery.
When the VDC warning light illuminates
when the VDC system is turned on, this light
alerts the driver to the fact that the VDC
system’s fail-safe mode is operating, for
example the VDC, active trace control (if so
equipped), Rise-up & Build-up function,
Brake Force Distribution or hill start assist
system may not be functioning properly.
Have the system checked. It is recommended
you visit an INFINITI retailer for this service.
If a malfunction occurs in the system, the
VDC system function will be canceled but
the vehicle is still driveable. For additional
information, see “Vehicle Dynamic Control
(VDC) system” (P.5-123).
