Active high beams – AHB*
AHB is a feature that uses a camera at the
upper edge of the windshield to detect the
headlights of oncoming vehicles or the tail-
lights of a vehicle directly ahead. When this
happens, the headlights will automatically
switch from high beams to low beams. When
the camera no longer detects the headlights/
taillights of other vehicles, your headlights will
switch back to high beams after several sec-
onds.
To activate this feature, turn the light switch to
the
position. Activation will occur if the
engine has been running for at least
20 seconds and the vehicle's speed is at least
12 mph (20 km/h).
Light switch in the AUTO position
Activate/deactivate AHB by pulling the left
steering wheel lever rearward (toward the
steering wheel) as far as possible and releasing
it. If AHB is deactivated while the high beams
are on, the headlights will switch to low beams.
When AHB is activated, the symbol
will illuminate in the instrument panel. The high
beam indicator ( ) in the instrument panel
will also illuminate when the high beams are on.
NOTE
• Keep the windshield in front of the cam-
era free of ice, snow, dirt, etc.
• Do not mount or in any way attach any-
thing on the windshield that could
obstruct the camera.
If the symbol illuminates in the instru-
ment panel and AHB unavailable is displayed,
switching between high and low beams will
have to be done manually. The light switch can
remain in the AUTO position. The same applies
if
Windscreen Sensors blocked is displayed
and the symbol is displayed. The
symbol will go out when these mes-
sages are displayed.
AHB may be temporarily unavailable (e.g., in
heavy fog or rain). When AHB becomes active
again or if the sensors in the windshield are no
longer obscured, the messages will disappear
and the symbol will illuminate.
