Introduction
Applies to: vehicles with screens in rear
Using screens in the rear, you can play multime-
dia content in the rear seats of your vehicle. The
screens are controlled either using the touch dis-
play or the applicable app on your mobile device,
depending on the context.

ZA WARNING
—As the driver, do not allow usage of the
screens in the rear to distract you from driv-
ing, as this could increase the risk of an acci-
dent. For example, do not reach behind you
while driving to operate the screens in the
rear.
— Children in rear-facing child safety seats in
the rear: remove the screens in the rear
from the backrests on the front seats to re-
duce the risk of injury. Read the instructions


in the chapter > page 88.


2) At the time this manual was printed, screens in the rear
were equipment in development. Your vehicle may not be
equipped with screens in the rear.

— The screens in the rear can only be operated
when the vehicle is stationary or when they
are securely positioned in the designated
holders in the vehicle. Like all loose objects,
they could be thrown through the vehicle
and cause serious injuries in a collision. If
the screens in the rear are not in the desig-
nated holders, they must always be securely
stowed while driving.
— Do not use any wireless devices on the front
seats within range of the airbags while driv-
ing. Also read the warnings in the chapter
> page 84.
CG) Note
