Intelligent Key warning light
After the ignition switch is pushed to the ON
position, this light comes on for about 2 sec-
onds and then turns off.
This light warns of a malfunction with the
electrical steering lock system or the Intelligent
Key system.
If the light comes on while the engine is
stopped, it may be impossible to free the
steering lock or to start the engine. If the light
comes on while the engine is running, you can
drive the vehicle. However in these cases, con-
tact an INFINITI retailer for repair as soon as
possible.
Lane departure warning light
(orange; if so equipped)
When the ignition switch is pushed to the ON
position, the light will come on in orange, turn
green, and then turn off. This indicates that the
Lane Departure Warning (LDW) and Lane Depar-
ture Prevention (LDP) systems are operational.
While the LDW and/or LDP system is on, the
light will blink in orange and a warning chime
will sound if the vehicle is traveling close to
either the left or the right of a traveling lane
with detectable lane markers. If the light comes on in orange and remains on,
it may indicate that the LDW and LDP systems
are not functioning properly. Although the ve-
hicle is still driveable, have the systems
checked by an INFINITI retailer.
See “LANE DEPARTURE WARNING (LDW)/ PRE-
VENTION (LDP) SYSTEM” in the “5. Starting and
driving” section.
Low tire pressure warning
light
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors the
tire pressure of all tires except the spare.
The low tire pressure warning light warns of low
tire pressure or indicates that the TPMS is not
functioning properly.
After the ignition switch is pushed ON, this light
illuminates for about 1 second and turns off.
Low tire pressure warning :
If the vehicle is being driven with low tire
pressure, the warning light will illuminate. A
CHECK TIRE PRESSURE warning (if so equipped)
also appears in the dot matrix liquid crystal
display. If you select the tire pressure informa-
tion in the display, the LOW PRESSURE informa-
tion will be displayed. The tire pressure for each
tire will also be displayed.
2-14Instruments and controls

When the low tire pressure warning light illumi-
nates, you should stop and adjust the tire
pressure to the recommended COLD tire pres-
sure shown on the Tire and Loading Information
label. The low tire pressure warning light does
not automatically turn off when the tire pres-
sure is adjusted. After the tire is inflated to the
recommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h) to
activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.
The CHECK TIRE PRESSURE warning (if so
equipped) is active as long as the low tire
pressure warning light remains illuminated.
For additional information, see “DOT MATRIX
LIQUID CRYSTAL DISPLAY” later in this section,
“TIRE PRESSURE MONITORING SYSTEM (TPMS)”
in the “5. Starting and driving” section and
“TIRE PRESSURE MONITORING SYSTEM (TPMS)”
in the “6. In case of emergency” section.
TPMS malfunction :
If the TPMS is not functioning properly, the low
tire pressure warning light will flash for approxi-
mately 1 minute when the ignition switch is
pushed ON. The light will remain on after 1
minute. Have the system checked by an INFINITI
retailer. The CHECK TIRE PRESSURE warning (ifso equipped) does not appear if the low tire
pressure warning light illuminates to indicate a
TPMS malfunction.
For additional information, see “TIRE PRESSURE
MONITORING SYSTEM (TPMS)” in the “5. Start-
ing and driving” section.
WARNING
●
If the light does not illuminate with the igni-
tion switch pushed ON, have the vehicle
checked by an INFINITI retailer as soon as
possible.
● If the light illuminates or LOW PRESSURE
information 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 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 In-
formation label to turn the low tire pressure
warning light OFF. If the light still illumi-
nates 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 re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
