affix anything on the windshield to block this sensor.
The lights automatically turn off when the driver’s door is

switch. If you are going to park for over one week, make sure
the headlight switch is off.

is turned fully on.

17 Daytime Running Light System (Canada only)
The headlights turn on when the parking brake is released with
the engine started, even with the light switch in the “OFF”
position. They will not go off until the ignition switch is turned
off.
To turn on the other exterior lights and instrument panel lights,
twist the knob to the first clickstop.
Under the daytime running light system, the headlights turn on
at reduced intensity. Twist the knob to the second clickstop to
turn to full intensity for driving at night.
When setting the knob to the third clickstop (“AUTO”), the
headlights will automatically adjust to full intensity and / or turn
on the other lights depending on the darkness of the
surroundings. Likewise, as the surroundings become brighter,
the headlights will turn to reduced intensity, ultimately turning
