▌Notes on telephony

WARNING Risk of distraction from operat-

ing integrated communication equipment

while the vehicle is in motion

If you operate communication equipment inte-

grated in the vehicle when driving, you could

be distracted from the trac situation. This

could also cause you to lose control of the

vehicle.

Only operate this equipment when the

trac situation permits.

If you cannot be sure of this, stop the

vehicle whilst paying attention to road

and trac conditions and operate the

equipment with the vehicle stationary.

WARNING Risk of accident from operating

mobile communication equipment while

the vehicle is in motion

Mobile communication devices distract the

driver from the trac situation. This can also

cause the driver to lose control of the vehicle.

As a driver, only operate mobile commu-

nication devices when the vehicle is sta-

tionary.

As a vehicle occupant, use mobile com-

munication devices only in the designa-

ted area, e.g. in the rear passenger com-

partment.

You must observe the legal requirements for the

country in which you are currently driving when

operating the multimedia system and mobile com-

munication equipment in the vehicle.

WARNING Risk of injury due to objects

being stowed incorrectly

If objects in the vehicle interior are stowed

incorrectly, they can slide or be thrown around

252

and hit vehicle occupants. In addition, cup

holders, open stowage spaces and mobile

phone receptacles cannot always retain all

objects within.

There is a risk of injury, particularly in the

event of sudden braking or a sudden change

in direction.

Always stow objects so that they cannot

be thrown around in such situations.

Always make sure that objects do not

protrude from stowage spaces, parcel

nets or stowage nets.

Close the lockable stowage spaces

before starting a journey.

Always stow and secure heavy, hard,

pointed, sharp-edged, fragile or bulky

objects in the trunk/cargo compart-

ment.

Observe the additional information on stowing

mobile communications devices correctly:
