The cameras capture a maximum range of
330 ft/100 m.
Parking assistantThe concept
This system assists the driver in parking paral‐
lel to the road.
Ultrasound sensors measure parking spaces
on both sides of the vehicle.
The parking assistant calculates the best pos‐
sible 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 and
the parking assistant and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 137.
Hints Personal responsibility
The parking assistant does not relieve
the driver of responsibility for the vehicle dur‐
ing the parking procedure.
Watch the parking space and parking proce‐
dure closely and intervene if necessary; other‐
wise, there is the danger of an 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 danger of an acci‐
dent occurring.◀
Transporting loads
Loads that extend beyond the perimeter
of the vehicle are not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring.◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curbs.
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.

Parking using the parking assistant
Check the traffic situation as well
Loud sounds outside and within the vehi‐
cle can drown out the signal tones of the park‐
ing assistant and PDC.
Check the traffic situation around the vehicle
with your own eyes; otherwise, there is the
danger of an accident.◀

tinued if necessary.
Follow the instructions on the Control Display
to do this.
System limits
No parking assistance The parking assistant does not offer assis‐
tance in the following situations:
▷In tight curves.
Functional limitations
The system may not be fully functional in the
following situations:
▷When sensors are dirty or iced over.▷In heavy fog, rain or snowfall.▷On bumpy road surfaces such as gravel
roads.▷On slippery ground.▷On steep uphill or downhill grades.▷When leaves or snow has collected in the
parking space.
Limits of ultrasonic measurement
The detection of objects can reach the physi‐
cal limits of ultrasonic measurement, e.g., in
the following circumstances:
▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With elevated, protruding objects such as
ledges or cargo.▷With objects with corners and sharp edges.▷With objects with a fine surface structure,
such as fences.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before
or after a continuous tone sounds.

could lead to a fire, and with it the risk of seri‐
ous personal injury as well as property dam‐
age.
Do not touch hot exhaust pipes; otherwise,
there is the danger of getting burned.◀
Climate control windshield
The marked area is not covered with heat re‐
flective coating.
Use this area for garage door openers, devices
for electronic toll collection, etc.
Climate control laminated tinted
safety glass
The vehicle glass provides full protection
against the harmful effects of UV radiation on
the skin.
Mobile communication devices in thevehicle
Mobile communication devices in the ve‐
hicle
It is advised that you do not use mobile com‐
munication devices, e.g., mobile phones, in‐
side the vehicle without connecting them di‐
rectly to the external antenna. Otherwise, the
vehicle electronics and mobile communication
devices can interfere with each other. In addi‐
tion, there is no assurance that the radiation
generated during transmission will be dis‐
charged from the vehicle 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 hydroplan‐
ing. 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.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
Driving through water Drive though calm water only and only if it is
not deeper than. 9.8 inches/25 cm and at this
height, no faster than walking speed, up to 6 mph/10 km/h.
Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the
electrical systems and the transmission may
be damaged.◀
Braking safely
Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsive‐
ness. 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 ABS is in its
active mode.Seite 175Things to remember when drivingDriving tips175
Online Edition for Part no. 01 40 2 909 877 - VI/13
Objects in the area around the pedalsNo objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly fixed in
place.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, for example.◀
Driving in wet conditions When roads are wet coated with road salt or
there is heavy rain, briefly exert gentle pres‐
sure on the brake pedal every few miles.
Ensure that this action does not endanger
other road users.
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
Drive long or steep downhill gradients in the
gear in which the least braking is required.
Otherwise, the brake system may overheat, re‐
sulting in a reduction in the brake system effi‐ ciency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if necessary.
Avoid load on the brakes
Avoid placing excessive load on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brake wear
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 is un‐
available with the engine stopped.◀
Brake disc corrosion The corrosion on the brake discs and the con‐
tamination 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 occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops that exits under‐
neath the vehicle.
Traces of water under the vehicle like this are
normal.

Snow chain detection
The concept When using snow chains, settings should bemade via the iDrive for the snow chains being
applied.
The snow chain detection system supports
you by automatically showing the detected
state on the Control Display.
When snow chains are in use, the rear axle
steering of the Integral Active Steering is deac‐
tivated automatically.
At speeds above the maximum permitted
speed with snow chains of 30 mph/50 km/h,
the rear axle steering is activated again auto‐
matically.

factory-installed sockets in the vehicle as this
may damage the battery.◀
General information
Make sure that the battery is always suffi‐
ciently charged to guarantee that the battery
remains usable for its full service life.
The battery may need to be charged in the fol‐
lowing cases:▷When making frequent short-distance
drives.▷If the vehicle is not used for prolonged pe‐
riods, longer than a month.Starting aid terminals
In the vehicle, only charge the battery via the
starting aid terminals, refer to page 218, in the
engine compartment with the engine off.
Power failure After a temporary power loss, some equipment
needs to be reinitialized.
