BULBS
Headlamp condensation
The headlamps are vented to equalize pressure. When moist air enters
the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.
Replacing exterior bulbs
Check the operation of all the bulbs frequently.
