. When manually changing the head-
light mode to the high beam, if you turn

Tips for the high beam assist
system
. The high beam assist function recog-
nizes the condition surrounding the vehi-
cle based on the brightness of illumination
ahead of your vehicle, etc. Therefore, the
headlight mode may switch in some
situations that do not match to the driver s
sense.
. A bicycle or cargo cycle may not be
detected.
. Under the following situations, the
brightness of ambient illumination may
not be detected correctly and the high
beam assist function may not work prop-
erly. As a result, the glare of the high beam
may disturb the driving of an oncoming
vehicle or vehicle ahead. Also, the low
beam mode may continue although there
are no oncoming vehicles and vehicles
ahead. In the such cases, change the
headlight mode manually.
In bad weather (fog, snow, sand
storm, heavy rain, etc.)
When the windshield glass is dirty
or fogged
When the windshield is cracked or
damaged
When the stereo camera is de-
formed or the stereo camera lenses
are dirty
If there are lights similar to the
headlights or the tail lights in the
surrounding area
When an oncoming vehicle or ve-
hicle ahead is driven without its head-
lights and tail lights on
If the headlights of an oncoming
vehicle or the tail lights of a vehicle
ahead are dirty or discolored, or if the
light beams are not aimed correctly
When a rapid change of brightness
continues while driving
When driving on a road with many
ups and downs or uneven surfaces
When driving on a road with many
curves
When there are some objects that
reflect light strongly, such as a road
sign or a mirror in vehicle ahead
Instruments and controls/Light control switch
When the rear part of the vehicle
ahead, such as a container, reflects
light strongly
When the headlights of your vehicle
are damaged or dirty
When your vehicle is tilted, such as
in case the vehicle has a flat tire or is
being towed
Immediately after the engine has
started
. In the following conditions, the head-
light mode will not be automatically chan-
ged from the high beam to the low beam.
When your vehicle passes an on-
coming vehicle suddenly in a blind
curve
When another vehicle passes in
front of your vehicle
When an oncoming vehicle or ve-
hicle ahead comes in and out of view
because of continuous curves, median
strips, roadside trees, etc.
. If the stereo camera detects the light of
the front fog lights of an oncoming vehicle,
the headlight mode may change from the
high beam to the low beam automatically.
. The headlight mode may change from
the high beam to the low beam, or the low
beam mode may continue, when affected
by a street light, traffic signal, illumination
of an advertisement board, or a reflective
object such as a road sign and signboard.
