Intermittent wiping Only switch on intermittent wiping under wet
weather conditions or in the presence of
precipitation. When you select intermittent wiping, the rain
sensor is activated. The rain sensor sets a
suitable wiping interval depending on the
wetness of the sensor surface automatically.
!
Do not leave windshield wipers on an
intermittent setting when the vehicle is
taken to an automatic car wash or during
windshield cleaning. Windshield wipers will
operate in the presence of water sprayed
on the windshield, and windshield wipers
may be damaged as a result.
! If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical
effects may cause the windshield wipers to
wipe in an undesired fashion. This could
then damage the windshield wiper blades
or scratch the windshield. You should
therefore switch off the windshield wipers
when weather conditions are dry.
X Turn the combination switch to position
Ä or Å.
After the initial wipe, pauses between
wipes are controlled by the rain sensor
automatically.
Intermittent wiping is interrupted when the
vehicle is at a standstill and a front door is

Warning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury. G
Warning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly. Starting the engine

Do not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
