# Service bulletin 630714

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10148275
- Published by NHTSA: 2018\-11\-13
- Manufacturer's number: 630714
- Manufacturer's date: 2014\-04\-01
- NHTSA component: EQUIPMENT; EXTERIOR LIGHTING:HEADLIGHTS

## NHTSA's summary

"One or Both Xenon Headlights Aiming Downwards. CAUSE Both sides are aiming downwards: \* The most likely cause is a faulty or disconnected rear height sensor. In very extreme cases due to poor road conditions, both headlight assemblies could have the vertical aim ball socket adjuster disconnected, as noted below. Only one side is aiming downwards: \* The cause could be a ""disconnected"" vertical aim ball socket adjuster, resulting from excessive road vibration or sharp impacts \(pot holes\) through the suspension to the headlight assembly. Important Note: Follow the procedure outlined in this bulletin first; replacing headlight assemblies for a vertical aim ball socket adjuster issue is an excessive repair."

- [513114](/bulletins/10148420.md), 2018-11-13, Service bulletin: EXTERIOR LIGHTING:HEADLIGHTS. Headlight Cleaning System: Functional Operation Change. The customer complains that the headlight cleaning system is not working properly and only works after several actuating attempts. CAUSE The "functional" operation of the headlight cleaning system was changed with integration level F020\-14\-07\-500. The functional changes to the headlight cleaning system's operation will occur only after programming the vehicle with ISTA/P 2.53.0 or higher. INFORMATION The headlight cleaning system is no longer activated with the first stalk activation when the lights are on. The functional programming change now requires the stalk to be activated four times before headlight cleaning is activated. The change prevents automatic activation of headlight cleaning when the customer only wants to clean his/her windshield. This is normal operation and no parts should be changed.
