Parking assistant
The concept
Seite 127Driving comfortCONTROLS127
Online Edition for Part no. 01 40 2 961 168 - II/15
This system assists the driver in parking parallel
to the road.
Ultrasound sensors measure parking spaces on
both sides of the vehicle.
The parking assistant calculates the best possi‐
ble parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information issued by the PDC, the
parking assistant and, where applicable, the
rearview camera, and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 123.
Hints Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed - risk of accident. ◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent. ◀
Transporting cargo
Cargo that extends beyond the perimeter
of the vehicle is not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐ vene; otherwise, there is the risk of an acci‐
dent. ◀Curbs
The parking assistant may steer the vehi‐
cle over or onto curb if need be.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged. ◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.

Limits of ultrasonic measurement
Ultrasonic measuring might not function under
the following circumstances:▷For small children and animals.▷For persons with certain clothing, e.g.
coats.▷With external interference of the ultra‐
sound, e.g. from passing vehicles or loud
machines.▷When sensors are dirty, iced over, damaged
or out of position.▷Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme heat or strong wind.▷With tow bars and trailer couplings of other

Driving in wet conditionsWhen roads are wet or in heavy rain, press
brake pedal ever so gently every few miles.
Ensure that this action does not endanger other
traffic.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills Avoid stressing the brakes
Avoid placing excessive stress on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brakes
wearing out and possibly even brake failure. ◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking.
In addition, steering and brake assist are un‐
available with the engine stopped. ◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐
wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
needed.
Brake disc corrosion Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during brak‐
ing is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked vehicle When using the automatic climate control, con‐
densation water develops collecting under‐
neath the vehicle.
These traces of water under the vehicle are
normal.
Ground clearance Limited ground clearance
Observe the limited ground clearance of
the vehicle, e. g. while entering underground
parking garages or when driving over obsta‐
cles. Otherwise, damages to the vehicle may
result. ◀Seite 156DRIVING TIPSThings to remember when driving156
