2018 NISSAN ALTIMA SL high beam

Be sure you do not put anything on top
of the autolight sensor located in the top
side
1of the instrument panel. The au-
tolight sensor controls the autolight; if it
is covered, the autolight sensor reacts as
if it is dark out and the headlights will
illuminate. If this occurs while parked
with the engine off and the ignition
switch placed in the ON position, your
vehicle’s battery could become dis-
charged.

the lever forward. The high beam lights
come on and the

– When the headlights of the on-coming vehicle or the leading ve-
hicle are turned off, when the color
of the light is affected due to for-
eign materials on the lights, or
when the light beam is out of
position.
– When there is a sudden, continu- ous 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 surface is reflecting intense light towards
the front of the vehicle.
– When the container, etc. being towed by a leading vehicle is re-
flecting 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, be-
ing towed, etc. ∙ The timing of switching the low beam
and high beam may change under the
following situations.
– The brightness of the headlights of the oncoming vehicle or leading
vehicle.
– The movement and direction of the oncoming vehicle and the lead-
ing vehicle.
– When only one light on the oncom- ing vehicle or the leading vehicle is
illuminated.
– When the oncoming vehicle or the leading vehicle is a two-wheeled
vehicle.
– Road conditions (incline, curve, the road surface, etc.).
– The number of passengers and the amount of luggage. High Beam Assist operation
To activate the High Beam Assist system,
turn the headlight switch to the AUTO po-
sition
1and push the lever forward2
(high beam position). The

When the vehicle speed lowers to less than
approximately 16 mph (25 km/h), the head-
light uses the low beam.
To turn off the High Beam Assist system,
turn the headlight switch to the

– Driving on a steep downhill slopeor roads with sharp curves.
– Driving on a bumpy road surface, such as an uneven dirt road.
– If dirt, ice, snow or other material is covering the radar sensor area.
– Interference by other radar sources.
– The camera area of the windshield is fogged up, or covered with dirt,
water drops, ice, snow, etc.
– Strong light (for example, sunlight or high beams from oncoming ve-
hicles) enters the front camera.
Strong light causes the area
around the pedestrian to be cast in
a shadow, making it difficult to see.
– A sudden change in brightness oc- curs. (For example, when the ve-
hicle enters or exits a tunnel or a
shaded area or lightning flashes.)
– The poor contrast of a person to the background, such as having
clothing color or pattern which is
similar to the background. – The pedestrian’s profile is partially
obscured or unidentifiable due to
the pedestrian transporting lug-
gage, wearing bulky or very loose-
fitting clothing or accessories.
∙ The system performance may de- grade in the following conditions:
– The vehicle is driven on a slippery road.
– The vehicle is driven on a slope.
– Excessively heavy baggage is loaded in the rear seat or the trunk
room of your vehicle.
∙ The system is designed to automati- cally check the sensor’s (radar and
camera) functionality, within certain
limitations. The system may not de-
tect blockage of sensor areas covered
by ice, snow or stickers, for example.
In these cases, the system may not be
able to warn the driver properly. Be
sure that you check, clean and clear
sensor areas regularly. ∙ In some road and traffic conditions,
the AEB with Pedestrian Detection
system may unexpectedly apply par-
tial braking. When acceleration is nec-
essary, depress the accelerator pedal
to override the system.
∙ Excessive noise will interfere with the warning chime sound, and the chime
may not be heard.
