Ambient image sensor maintenance:
The ambient image sensor
for the high
beam assist system is located in front of the
inside mirror. To keep the proper operation
of the high beam assist system and prevent a
system malfunction, be sure to observe the
following:
. Always keep the windshield clean.
. Do not attach a sticker (including trans-
parent material) or install an accessory
near the ambient image sensor.
. Do not strike or damage the areas around
the ambient image sensor. Do not touch
the sensor lens that is located on the
ambient image sensor. If the ambient image sensor is damaged due
to an accident, it is recommended you
contact an INFINITI retailer.
Battery saver system
A chime will sound and the light reminder
warning will appear in the vehicle informa-
tion display when the driver side door is
opened with the light switch in the
orposition and the ignition switch in the
ACC, OFF or LOCK position.
When the headlight switch is in the
orposition while the ignition switch is in
the ON position, the lights will automatically
turn off after a period of time when the
ignition switch has been pushed to the OFF
position.
When the headlight switch remains in the
orposition after the lights auto-
matically turn off, the lights will turn on
when the ignition switch is pushed to the ON
position.
CAUTION
. When you turn on the headlight
switch again after the lights auto-
matically turn off, the lights will not
turn off automatically. Be sure to
turn the light switch to the OFF
position when you leave the vehicle for extended periods of time, other-
wise the battery will be discharged.
. Never leave the light switch on when
the engine is not running for a period
of time even if the headlights turn off
automatically.
Daytime running light system
The daytime running lights automatically
illuminate when the engine is started with
the parking brake released. The daytime
running lights operate with the headlight
switch in the OFF, AUTO or
position.
Turn the headlight switch to theposition
for full illumination when driving at night.
If the parking brake is applied before the
engine is started, the daytime running lights
do not illuminate. The daytime running lights
illuminate once the parking brake is released.
The daytime running lights will remain on
until the ignition switch is pushed to the OFF
position.
WARNING
When the daytime running light system
is active, tail lights on your vehicle are
not on. It is necessary at dusk to turn on
your headlights. Failure to do so could
cause an accident injuring yourself and

SONAR SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the sonar function. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may affect
the function of the system, including
reduced performance or a false acti-
vation.
. The system is not designed to pre-
vent contact with small or moving
objects.
. The system will not detect small
objects below the bumper, and may
not detect objects close to the bum-
per or on the ground.
. The system may not detect the
following objects:
— Fluffy objects such as snow, cloth, cotton, grass or wool.
— Thin objects such as rope, wire or chain. — Wedge-shaped objects.
. If your vehicle sustains damage to the
bumper fascia, leaving it misaligned
or bent, the sensing zone may be
altered causing inaccurate measure-
ment of objects or false alarms.
CAUTION
Excessive noise (such as audio system
volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
System temporarily unavailable
When the amber markers are displayed at
the corners of the vehicle icon and the
function cannot be activated from the
Parking sonar settings menu (the setting
items are grayed out), the sonar system may
be malfunctioning.
SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar (located on
the front and rear bumper fascia) free
from accumulations of snow, ice and dirt.
Do not scratch the surface of the sonar
when cleaning. If the sensors are cov-
ered, the accuracy of the sonar function
will be diminished.

— When there is dirt, water drops orsnow on the camera lens.
— When the position of the moving objects in the display is not chan-
ged.
. The MOD system might detect flow-
ing water droplets on the camera
lens, white smoke from the muffler,
moving shadows, etc.
. The MOD system may not function
properly depending on the speed,
direction, distance or shape of the
moving objects.
. If your vehicle sustains damage to the
parts where the camera is installed,
leaving it misaligned or bent, the
sensing zone may be altered and the
MOD system may not detect objects
properly.
. When the temperature is extremely
high or low, the screen may not
display objects clearly. This is not a
malfunction.

5-6Starting and driving
Please note that the TPMS is not a sub-
stitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct
tire pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.Additional information
.Since the spare tire (if so equipped) is not
equipped with the TPMS, the TPMS
does not monitor the tire pressure of
the spare tire.
. The TPMS will activate only when the
vehicle is driven at speeds above 16
MPH (25 km/h). Also, this system may
not detect a sudden drop in tire pressure
(for example a flat tire while driving).
. The low tire pressure warning light does
not automatically turn off when the tire
pressure 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 “Tire Pressure Low - Add Air”
warning appears in the vehicle informa-
tion display when the low tire pressure
warning light is illuminated and low tire
pressure is detected. The “Tire Pressure
Low - Add Air” warning turns off when
the low tire pressure warning light turns
off.
The “Tire Pressure Low - Add Air”
warning does not appear if the low tire
pressure warning light illuminates to
indicate a TPMS malfunction. .
The “Flat Tire - Visit dealer” warning (if
so equipped) appears in the vehicle
information display when the low tire
pressure warning light is illuminated and
one or more flat tires are detected.
. Tire pressure rises and falls depending on
the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure after driving
because the tire pressure rises after
driving. Low outside temperature can
lower the temperature of the air inside
the tire which can cause a lower tire
inflation pressure. This may cause the
low tire pressure warning light to illumi-
nate. If the warning light illuminates in
low ambient temperature, check the tire
pressure for all four tires.
. You can also check the pressure of all
tires (except the spare tire) in the vehicle
information display. (See “Vehicle infor-
mation display” (P.2-18).)
. After the ignition switch is placed in the
ON position, it may take a period of time
for the tire pressure to be displayed while
the vehicle is driven. Depending on the
radio wave circumstance, tire pressure
may not correctly be displayed.
For additional information, see “Low tire
pressure warning light” (P.2-13) and “Tire
Pressure Monitoring System (TPMS)” (P.6-
3).
