WARNING
• Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
• If the light does not illuminate with the
ignition switch placed in the ON position,
have the vehicle checked as soon as pos-
sible. It is recommended that 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. Driv-
ing with under-inflated tires may perma-
nently 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 per-
sonal injury or death. 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 located in the driver’s
door opening to turn the low tire pres-
sure 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 replace-
ment tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
•
When using a wheel without the TPMS
such as the spare tire, 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 rec-
ommended that you visit an INFINITI re-
tailer for these services.
• Replacing tires with those not originally
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.
Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or blinks
while the engine is running, it may indicate a
potential emission control malfunction.
The MIL may also come on steady if the
fuel-filler cap is loose or missing, or if the
vehicle runs out of fuel. Check to make sure
the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3 gal-
lons (11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for
20 seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance test.
For additional information, see “Readiness for
Inspection/Maintenance (I/M) test” (P. 10-35).

Adaptive Front lighting System
(AFS) (if so equipped)
The Adaptive Front lighting System (AFS) will
automatically adjust the headlights (low
beam) toward the turning direction to im-
prove the driver’s view. When the headlight
switch is ON and the driver operates the
steering wheel in a turn, the AFS system will
be activated.
The AFS will operate:
• when the headlight switch is ON.
• when the shift position is in any positionother than P (Park) or R (Reverse).
• when the vehicle is driven at above 16 mph (25 km/h) for the left-side headlight. Note
that the right-side low beam headlight will
swivel but the left side will not swivel when
the vehicle is at a stop and the steering
wheel is turned. The vehicle must attain a
speed above 16 mph (25 km/h) before AFS
activates the left-side headlight.
AFS will also adjust the headlight to a proper
axis automatically, depending on the number
of occupants in the vehicle, the load the ve-
hicle is carrying and the road conditions.
If the AFS OFF indicator blinks or the vehicle
information display shows an AFS system
error message after the ignition switch has been pushed to the ON position, this may
indicate that the AFS is not functioning prop-
erly. Have the system checked. It is recom-
mended you visit an INFINITI retailer for this
service. When the engine is started, the head-
lights will vibrate to check the system condi-
tion. This is not a malfunction.

switch in the OFF position or AUTO position
with bright ambient light. When you turn the
headlight switch to the
position for full
illumination, the LED lights switch from LED
DRL system to the park function. If the parking brake is applied before the
engine is started, the LED DRL system does
not illuminate. The LED DRL system illumi-
nates when the parking brake is released. The
LED DRL system will remain on until the
ignition switch is placed in the OFF position.
It is necessary at dusk to turn the headlight
switch on for interior controls and switches
to illuminate, as those remain off while the
switch is in the OFF position.
WARNING
When the LED DRL system is active, tail
lights on your vehicle are not on. It is nec-
essary at dusk to turn on your headlights.
Failure to do so could cause an accident
injuring yourself and others.
