Maintenance and care
Replacing tail lamp/turn/backup lamp bulbs
The tail lamp/turn/backup lamp
bulbs are located the tail lamp
assembly, one just below the other.
Follow the same steps to replace
either bulb:
1. Remove the four screws and the
lamp assembly from vehicle.
2. Rotate bulb socket
counterclockwise and remove from
lamp assembly.
3. Carefully pull the bulb straight
out of the socket and push in the
new bulb.
4. Install the bulb socket in lamp
assembly by turning clockwise.
5. Install the lamp assembly and
secure with four screws.
USING THE RIGHT BULBS
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized "D.O.T." for North America and an
"E" for Europe to assure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.
