Overview
The interior lighting system consists of:
Courtesy lamps
Demand lamps
Ambient lighting
The
courtesy lamps provide illumination to the vehicle interior, front
scuff plates, exterior door handles, rear puddle lamps and below the
exterior mirrors when entering or exiting the vehicle or when requested
using the courtesy lamp switch located on the headlamp switch...
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage...
