Lights
Headlight and taillight lenses become dirty during normal operation.
Clean all lights frequently to ensure a clear field of vision as well as
visibility to other vehicles.
When servicing a halogen lamp, don't touch the lamp with bare fingers.
Oil from your skin leaves a residue, causing a hot spot that will shorten
the life of the lamp.
LED Headlamps (if equipped)
If a headlight becomes damaged or inoperable, the entire headlight
assembly must be replaced.
Tip: If an LED headlamp has moisture or fogging inside, disconnect the wiring
harness from the headlamp(s) for a few days to allow the moisture to clear
out. Do not operate the vehicle at night or in low light conditions without
properly working headlights.
Headlight Lamp Replacement
Do not service the headlamps until they've cooled sufficiently.
1. Unplug the headlamp from
the wiring harness. Be sure
to pull on the connector,
not on the wiring.
2. Turn the lamp counter-
clockwise to remove it.
3. Install the new lamp. Make
sure the tab on the lamp
locates properly in the
housing.
4. Reinstall the harness assembly into the headlight assembly.
