RAIN-SENSING AUTO WIPER
SYSTEM
The rain-sensing auto wiper system can
automatically turn on the wipers and adjust
the wiper speed depending on the rainfall
and the vehicle speed by using the rain
sensor located on the upper part of the
windshield.
To set the rain-sensing auto wiper system,
push the lever down to the AUTO position
. The wiper will sweep once while the
ignition switch is in the ON position.
The rain sensor sensitivity level can be
adjusted by turning the knob toward
(High) or toward(Low). .
High — High sensitive operation
. Low — Low sensitive operation
To turn the rain-sensing auto wiper system
off, push up the lever to the OFF position, or
pull down the lever to the LO or HI position.
CAUTION
Do not touch the rain sensor and around
it when the wiper switch is in the AUTO
position and the ignition switch is in the
ON position. The wipers may operate
unexpectedly and cause to an injury or
may damage a wiper.
. The rain-sensing auto wipers are in-
tended for use during rain. If the switch
is left in the AUTO position, the wipers
may operate unexpectedly when dirt,
fingerprints, oil film or insects are stuck
on or around the sensor. The wipers may
also operate when exhaust gas or
moisture affect the rain sensor.
. The rain-sensing auto wipers may not
operate if rain does not hit the rain
sensor even if it is raining.
. When the windshield glass is coated
with water repellent, the speed of the
rain-sensing auto wipers may be higher
even though the amount of the rainfall is
small.

.Be sure to turn off the rain-sensing auto
wiper system when you use a car wash.
. Using genuine wiper blades is recom-
mended for proper operation of the
rain-sensing auto wiper system. (See
“Windshield wiper blades” (P.8-21) for
wiper blade replacement.)

switch automatically under the fol-
lowing conditions. Switch the high
beam and low beam manually.

— When a light source similar to a headlight or tail light is in the
vicinity of the vehicle. — When the headlights of the on-
coming vehicle or the leading
vehicle are turned off, when the
color of the light is affected due to
foreign materials on the lights, or
when the light beam is out of
position.
— When there is a sudden, contin- uous change in brightness.
— When driving on a road that passes over rolling hills, or a road
that has level differences.
— When driving on a road with many curves.
— When a sign or mirror-like sur- face is reflecting intense light
towards the front of the vehicle.
— When the container, etc. being towed by a leading vehicle is
reflecting intense light.
— When a headlight on your vehicle is damaged or dirty.
— When the vehicle is leaning at an angle due to a punctured tire,
being towed, etc.

others.
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
improve the driver’s view. When the head-
light 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 lever is in any position
other than P (Park) or R (Reverse).
. when the vehicle is driven at above 3
MPH (5 km/h) for the left-side head-
light. Note that the right-side low beam
headlight will swivel but the left-side
headlight will not swivel when the vehicle
is below 3 MPH (5 km/h) and the
steering wheel is turned.
AFS will also adjust the headlight to a proper
axis automatically, depending on the number
of occupants in the vehicle, the load the
vehicle is carrying and the road conditions.
If the AFS warning appears in the vehicle
information display after the ignition switch
has been pushed to the ON position, this may indicate that the AFS is not functioning
properly. Have the system checked. It is
recommended you visit an INFINITI retailer
for this service. When the engine is started,
the headlights will vibrate to check the
system condition. This is not a
malfunction.

The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system on for most
driving conditions.
If the vehicle is stuck in mud or snow, the
VDC system reduces the engine output to
reduce wheel spin. The engine speed will be
reduced even if the accelerator is depressed
to the floor. If maximum engine power is
needed to free a stuck vehicle, turn the VDC
system off.
To turn off the VDC system, push the VDC
OFF switch. The
indicator light will
illuminate.
Push the VDC OFF switch again or restart
the engine to turn on the system. (See
