Lights Always remember to turn on your headlamps at dusk or during inclement weather. The Daytime Running Lamp (DRL) system does not activate the tail lamps and generally may not provide adequate lighting during these conditions. Failure to activate your headlamps under these conditions may result in a collision. PANEL DIMMER CONTROL Use to adjust the brightness of the instrument panel and all applicable switches in the vehicle during headlamp and parking lamp operation. Move the control to the full upright position, past detent, to turn on the interior lamps. Move the control to the full down position, past detent, to prevent the interior lights from illuminating when the doors are opened. When the control is in the full down position, it acts as a dome lamp defeat/override. Note: If the battery is disconnected, discharged, or a new battery is installed, the dimmer switch requires re-calibration. Rotate the dimmer switch from the full dim position to the full Dome/ON position to reset. This will ensure that your displays are visible under all lighting conditions. AIMING THE HEADLAMPS The headlamps on your vehicle are properly aimed at the assembly plant. If your vehicle has been in an accident the alignment of your headlamps should be checked by your authorized dealer. Vertical aim adjustment Before aim adjustment, disable the air suspension system.
