Rear Seat Remote
Introduction
Applies to: vehicles with Rear Seat Remote
With Rear Seat Remote, you can control conven-
ience and Infotainment system functions in the
rear of the vehicle, such as the climate control
system or the media playback in the vehicle.

ZA\ WARNING
— As the driver, do not allow usage of the Rear
Seat Remote to distract you from driving, as
this could increase the risk of an accident.
For example, do not reach behind you while
driving to operate the Rear Seat Remote.
— The Rear Seat Remote can only be operated
when the vehicle is stationary or when the
remote is securely positioned in the desig-
nated holder in the vehicle. Like all loose ob-
jects, it could be thrown through the vehicle
and
cause serious injuries in a collision. If
the Rear Seat Remote is not in the designat-
ed holder, it 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.
— The Rear Seat Remote can become hot while
charging. Pay attention to the housing and
display temperature, and be careful when

26


removing the Rear Seat Remote from the
holder.
— There are magnets located on the back of
the Rear Seat Remote and in the designated
holder. For people with pacemakers, the
electromagnetic radiation may impair pace-
maker function. Always maintain a mini-
mum distance of approximately 6 inches (15
cm) from the magnets.

@) Note
— Always follow the information found in 9®
in General information on page 222.
— Protect the Rear Seat Remote against pro-
longed exposure to direct sunlight.

Rear Seat Remote and/or impair the device
performance. Never leave your Rear Seat
Remote in the vehicle in extremely high or
low temperatures.
— Protect the Rear Seat Remote from coming
into contact with any fluids.
G) Tips
— Please note that the Rear Seat Remote can
be used only when the ignition is switched
on and within range of your vehicle's active
Wi-Fi hotspot.
— Please note that a Wi-Fi connection does
not automatically make it possible to use
the Internet. For additional information,
see the chapter > page 222.
— When playing online media sources, there
may be longer loading times or restrictions
on media playback, depending on the Inter-
net connection or the Wi-Fi usage (for ex-
ample, if there is intensive usage by multi-
ple devices on the hotspot).
— Signals from Bluetooth devices and Wi-Fi
hotspots within range of the vehicle may
impair the vehicle Wi-Fi services. If multiple
Bluetooth devices and Wi-Fi hotspots are
within range of the vehicle, it may cause re-
duced data transfer rates, connection inter-
ruptions, or limitations when streaming me-
dia.
