General driving notes
Closing the trunk lid
Safety information
Warning
An open trunk lid protrudes from the vehicle
and can endanger occupants and other traffic
participants or damage the vehicle in the event
of an accident, braking or evasive maneuvers.
In addition, exhaust fumes may enter the car's
interior. There is a risk of injury or risk of dam‐
age to property. Do not drive with the trunk lid
open.
Driving with the trunk lid open
If driving with the tailgate open cannot be
avoided:
▷ If the convertible top is closed, close all win‐
dows.
▷ Greatly increase the air flow from the vents.
▷ Drive moderately.
Hot exhaust gas system
Warning
During driving operation, high temperatures can
occur underneath the vehicle body, for instance
caused by the exhaust gas system. If combusti‐
ble materials, such as leaves or grass, come in
contact with hot parts of the exhaust gas sys‐
tem, these materials can ignite. There is a risk
of injury or risk of damage to property. Do not
remove the heat shields installed and never ap‐
ply undercoating to them. Make sure that no
combustible materials can come in contact with
hot vehicle parts in driving operation, idle or
during parking. Do not touch the hot exhaust
gas system.
Mobile communication devices
in the vehicle
Warning
Vehicle electronics and mobile phones can in‐
fluence one another. There is radiation due to
the transmission operations of mobile phones.
There is a risk of injury or risk of damage to
property. If possible, in the car's interior use
only mobile phones with direct connections to
an exterior antenna in order to exclude mutual
interference and deflect the radiation from the
car's interior.
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplaning.
It is characterized by a partial or complete loss of
contact between the tires and the road surface,
ultimately undermining your ability to steer and
brake the vehicle.
