WARNING
Operating the integrated information systems and communications equipment in the vehicle
whil edriving willd istract you from traffic con-
ditions. You could then lose control of the
vehicle .There is arisk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure aboutt he
surrounding conditions, pullo ver toasafe
locatio nand make entries only whilet he vehi-
cle is stationary.
You must observe the legalr equirements for the

The multimedia system calculates the route to
the destination withou ttaking the following into
account, for example:
R traffic lights
R stop and give way signs
R parking or stopping restrictions
R road narrowing
R other road and traffic rulesa nd regulations
The multimedia system may give incorrect nav-
igation recommendations if the actual street/
traffic situation does not correspond with the
digital map's data.
For example:
R ad iverted route
R the road layout or the direction of aone-way
street has been changed
For this reason, you must alwayso bserve road
and traffic rulesa nd regulations during your
journey. Roada nd traffic rulesa nd regulations
alwaysh ave priority over multimedia system

flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey. G

become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is arisk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
The handling characteristics of aladen vehicle
are dependent on the distribution of the load
within the vehicle. For this reason, you should
observe the following notes when transporting a
load:
R never exceed the maximum permissible gross
vehicle weight or the permissible axle loads
for the vehicle (including occupants).
R the boot is the preferred place to store
objects.
R position heavy loads as far forward as possi-
ble and as low down in the boot as possible. R
the load must not protrude above the upper
edge of the seat backrests.
R always place the load behind unoccupied
seats if possible.
R secure the load with sufficiently stronga nd
wear-resistant lashing material. Pad sharp
edges for protection.
