Install the tail lamps
First remove the rear (1), then the
front (2) tail lamp from the recesses.
Open out the bulb holder on the back
of the tail lamp completely.
Push the clamping lever down and
push the bulb holder into the retainer
until it hits the stop.
Perform this procedure for both tail
lamps.
Check the cable and lamp position to
make sure these are correctly
installed and are securely located.
