Floormats
G WARNING
Make sure that there is sufficient clearance
around the pedals when floormats are used,
and that the floormats are properly secured.
The floormats must be correctly secured at all
times using retainers and press-studs.
Before you drive off, check the floormats and
secure if necessary. A floormat which is not
properly secured can slip and, thereby, inter-
fere with the movement of the pedals.
Do not place floormats on top of one another.
Floormat on the driver's side (example)

Infrared reflective windscreen
The infrared reflecting glass prevents the
vehicle interior from becoming too hot. It also
blocks radio waves up into the gigahertz
range.
In order to operate radio-controlled equip-
ment, e.g. toll recording systems, areas : on
the windscreen are permeable to radio
waves. In these areas, you can install radio-
controlled systems.
These areas can best be seen from outside
the vehicle by observing the light reflected off
the windscreen.
Retrofitted anti-glare film
Anti-glare film retrofitted to the inside of the
windows can interfere with radio/mobile
phone reception. This is particularly the case
for conductive or metallic-coated films. Infor-
mation about anti-glare film can be obtained
from any Mercedes-Benz Service Centre.
