• The factory-fitted  towing bracket  is not  attached 
ele ctrically  to a trailer . 
• A minimum  engine temperature  has been 
rea ched . 
198 I While driving 
• The ve hicle has been moved since the engine 
was las t switc he d off. 
• F or  v ehicle s  with  Climatronic: the temperatu 
inside  the ve hicle is  within  the pre-set temperat~~e 
ra nge . 
• The  de frost  function of the air conditioning sys.

When  the condit ions 
for automatic  engine swit ch
off  are only fulfilled  when the vehicle  is stationary, 
the  engine  can also  switch  off subsequently : 
• When the driver  creates  the required conditions 
by performing  an action , e .g . by switching off the 
defrost  function .

tance control. 
• If the  vehicle  ahead has moved on. 
The brake servo and the electromechanical 
steering will not function if the engine is 
switched off. 
• Never allow the vehicle to roll if the engine 
is switched off.

if work is to be carried out in the engine com
partment. 
Downhill driving assistant 
rf'n First read and observe the introductory 
~ information and safety warnings £ on 
page  196. 
The downhill  driving assistant  in veh icles  with an 
~utomatic gearbox  helps when  braking and travel
ling downhill ~ £. The downhill  driving assistant 
uses the braking power of the  engine . 
The automatic  gearbox selects the best gear for 
t~e circums tances by taking  the steepness of the 
h1l.l and the current  speed into  consideration. To do 
th1s the selector  lever must be in position  D or S. 
The downhill  driving assistant  is not active in Tip
Ironic mode . 
As the downhill driving  assistant  can only  shift 
down as far as the 3rd gear, it may be necessary 
to activate  the Tiptronic mode when  driving down 
If the start/stop system is used in very high 
outside temperatures over a long period, the 
vehicle battery can be damaged. 
m In some  cases,  it may be necessa ry  to  restart 
L!J the  engine manually. F ollow any correspond

select  the 2nd or 1st gear  manually  in order to 
make use of the braking  effect of the engine and to 
relieve  the brakes . 
Activating the downhill driving assistant 
automatically: 
• If the incline is greater  than approximately  6%. 
• AND: if the selector  lever is in  position  0 or s. 
• In addition, if the CCS or ACC is switched 
off: if the  vehicle  speed is less  than  approximately 
80 km/h (50 mph) or the  brake  pedal is depressed. 
• In addition if the CCS or ACC is active: if the 
stored  speed is exceeded .

The ParkPilot assists  the driver  when manoeuvring 
and parking . If the vehicle is approaching  an obsta
cle located in the range of the ultrasound sensors , 
an intermittent  acoustic warning is sounded , de
pending on the distance . The shorter the distance , 
the shorter the intervals . The acoustic  warning will 
sound continuously if the obstacle is very close . 
The ultrasound sensors in the bumpers  transmit 
and receive ultrasound waves. The  system  uses 
the time difference  between the ultrason ic waves 
(i.e. between  the transmission  and reflection  from 
obstacles and the point of reception)  to continu
ously calculate the distance  between  the bumper 
and the obstacle. 
Additional information and warnings: 
• Exterior views ~page 6 
• lnfotainment system ~page 31 
• Braking , stopping  and parking ~page 179 
• Reverse  assist system  (Rear Assist) 
~page 209 
•  Park 
assist  system (Park Assist) ~page 213 
•  Cleaning and  caring  for the vehicle exterior 
~page 294 
• Accessories , modificat ions , repairs  and renewal 
of parts ~page 320 
A WARNING 
The ParkPilot cannot replace the full concen
tration of the driver. 
• Unintentional vehicle movements can 
cause serious injury. 
• Always adapt your speed and driving style 
to suit visibility, weather, road and traffic con
ditions. 
• Ultrasound sensors have blind spots in 
Which obstacles and people cannot be detec
ted '--. 
A WARNING (Continued) ~-
• Always monitor the area around the vehi
cle as the ultrasound sensors will not always 
detect infants, animals and objects. 
• Certain surfaces of objects and clothes 
cannot reflect the signals from the ultrasound 
sensors. The system is unable to detect 
these objects or people wearing this type of 
clothing, or they may be detected incorrectly. 
• External sources of sound can affect the 
signals of the ultrasound sensors. In certain 
circumstances, the system may not recog
nise people or objects. 
A WARNING ~-. 
Automatic activation of the ParkPilot only oc
curs at very low speeds. An inappropriate 
driving style can cause accidents and serious 
injuries. 
• Always bear in mind the time delay be
tween the signals. 
• The ultrasound sensors may not always be 
able to detect objects such as trailer drawbars, 
thin rails, fences, posts, trees and open or 
opening tailgates. This can result in damage to 
your vehicle. 
• If the ParkPilot has detected an obstacle 
and issued a warning, the obstacle may move 
out of the detection range of the sensors as the 
vehicle approaches it, particularly if the object 
is very high or very low. These objects are no 
longer registered. 
• The vehicle can sustain considerable dam
age if the warning given by the ParkPilot is ig
nored. 
• The ultrasound sensors in the bumper can 
be displaced or damaged through impacts, e.g. 
when parking. 
• The ultrasound sensors in the bumpers 
must be kept clean and free of ice and snow 
and not be covered up by stickers or other 
items, as these may prevent the system from 
working properly.
