Active high beams (AHB)*
AHB uses a camera at the upper edge of the windshield to detect the headlights of oncomingvehicles or the taillights of a vehicle directlyahead. When this happens, the headlights willautomatically switch from high beams to lowbeams. When the camera no longer detects theheadlights/taillights of other vehicles, your head-lights will switch back to high beams after sev-eral seconds.
To activate AHB:
• Turn the headlight control to the
posi-
tion.
The feature will begin functioning if the engine has been running for at least 20 seconds and thevehicle's speed is at least 12 mph (20 km/h).
Headlight switch in the AUTO position
Switch AHB on or off by pulling the left steering wheel lever rearward (toward the steering wheel)as far as possible and releasing it. If AHB isswitched off while the high beams are on, theheadlights will change to low beams.
Models with an analog instrument panel
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.
Models with a digital instrument panel
When AHB is activated, will illuminate as a
white symbol in the instrument panel. When the
high beams are on, the symbol will change to blue.
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 couldobstruct the camera.
If Active high beam Temporary unavailable
Switch manually is displayed in the instrument
panel, switching between high and low beams will have to be done manually. However, the light switch can remain in the
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 activeagain or if the sensors in the windshield are nolonger obscured, the messages will disappear and the
symbol will illuminate.
CAUTION
In the following situations, it may be neces- sary to switch between high and low beamsmanually:
• In heavy fog or rain
• In blowing snow or slush

Headlight switch in the parking light position
Canadian models: If the ignition is in position II
or the engine is running, the daytime running lights will also be on. With the headlight switch in this position, the parking lights will remain on even when the igni-tion is switched off. In dark ambient lighting conditions, the rear park- ing lights also illuminate when the trunk isopened to alert anyone traveling behind yourvehicle. This happens regardless of the positionthat the headlight control is in or which mode theignition is in.
