DRIVING TIPS
hot vehicle parts while driving, at idle or during
parking.
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 external antenna in order to exclude mutual
interference and deflect the radiation from the
car's interior.
Aquaplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as aquaplaning.
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.

Safety information
NOTICE
When driving too quickly through too deep wa‐
ter, water can enter into the engine compart‐
ment, the electrical system or the transmission.
There is a risk of damage to property, among
other potential damage. When driving through
water, do not exceed the maximum indicated
water level and the maximum speed for driving
through water.
Braking safely
General information
The vehicle is equipped with an Antilock Braking
System ABS as a standard feature.
Perform emergency braking in situations that re‐
quire such.
Steering is still responsive. You can still avoid any
obstacles with a minimum of steering effort.
Pulsation of the brake pedal and sounds from the
hydraulic circuits indicate that the Antilock Brak‐
ing System ABS is in its active mode.
In certain braking situations, the perforated brake
discs can emit functional noises. However, func‐
tional noises have no effect on the performance
and operational reliability of the brake.
Objects in the area around the
pedals
Warning
Objects in the driver's floor area can limit the
pedal distance or block a depressed pedal.
There is a risk of accident. Stow objects in the
vehicle such that they are secured and cannot
enter into the driver's floor area. Use floor mats
that are suitable for the vehicle and can be
safely attached to the floor. Do not use loose
floor mats and do not layer several floor mats.
Make sure that there is sufficient clearance for
