Affected Vehicles
Condition
Low beam stays on at highway speeds with headlight switch set to parking lights.
75
-ORWhen
slowing down, approaching an intersection, or in tight turns, the low beams turn off automatically with the headlight switch set to parking
lights (with or without fog lights activated).
These are normal conditions. The headlight system functions properly during these conditions.
Technical Background
There is a normal condition where the headlight low beams will stay on even when the headlight switch is moved to the parking light position with
the vehicle moving at a speed of 19mph (30km/h) or higher. These conditions may only occur during a long trip and the headlight switch position is
changed late in the trip.
^ With the headlight switch set to the "Auto" position and with the low beams automatically activated, the low beams will stay on even when the
headlight switch is set to the parking light position if the vehicle is moving over 19mph (30 km/h). When the vehicle speed drops below
19mph (30 km/h), and with the headlight switch in the parking light position, the low beams will automatically switch off.
^ With the headlight switch set to the "low beam" position, the low beams will stay on even when the headlight switch is set to the parking light
position if the vehicle is moving over 19mph (30km/h). When the vehicle speed drops below 19mph (30 km/h), and with the headlight switch
in the parking light position, the low beams will automatically switch off.
This can be a common occurrence for those customers who enjoy driving with the vehicle's fog lights on all the time or during dusk because the
headlight switch will likely be moved from the Auto position to the parking light position.
This condition can also happen unintentionally when a customer tries to switch from the "low beam" position to the "Auto" position with the fog
lights activated (switch pulled out). The headlight switch can only be physically turned to the "parking light" position with the fog lights activated.
The headlight switch needs to be pushed back in to allow it to move from the low beam position to the Auto position.
