Police Package and Special Service Package

The following exterior lighting features apply to vehicles first sold in the United States.

The vehicle has Daytime Running Lamps (DRL) and an Automatic Headlamp System (AHS). The DRL and AHS can be turned to OFF with the headlamp switch when the transmission is in P (Park) and the engine is at idle. If the engine is not turned off, the DRL and AHS will remain OFF when the transmission is placed in gear. The vehicle may be driven with the lamps off for one ignition cycle.

The vehicle may have been built with SEO 9G8, DRL AND AHS DISABLE. This feature turns off DRL and AHS and requires manual control of the exterior lighting. See your dealer/retailer to restore the DRL and AHS to normal operation.

For vehicles first sold in Canada, the DRL and AHS can be turned off if the transmission is in P (Park). See the owner's manual for more information.
