2018 MERCEDES-BENZ CLA COUPE ECU

!Mercedes-Benz recommends that you only
use roof carriers that have been tested and
approved for Mercedes-Benz vehicles. This
helps to prevent damage to the vehicle.
Position the load on the roof rack in such a
way that the vehicle will not sustain damage
even when it is in motion.
Depending on the vehicle equipment, ensure
that when the roof carrier is installed you can:
Ropen the panorama roof with power tilt/
sliding panel fully
Ropen the trunk lid fully
You will find information on the maximum roof
load in the "Technical data" section
(
Ypage 320).
An incorrectly secured roof carrier or roof load
may become detached from the vehicle. You
must therefore ensure that you observe the roof
carrier manufacturer's installation instructions.
Attaching the roof carrier
XOpen and fold the covers :upwards care-
fully in the direction of the arrow.
XOnly secure the roof carrier to the anchorage
points under covers :.
XObserve the manufacturer's installation
instructions.
