Operation, Safety
Parking Aids Parking assistantWhen the driver backs up, the parking assistant
system indicates the distance between the car
and a large obstacle behind it, by means of signal
tones.
Warning!
Risk of serious personal injury or death.
Parking assistant cannot detect small ob-
jects such as children and pets.
Despite use of the parking assistant system,
the driver is still responsible for taking due
care and assessing obstacles when backing
up.
f Make sure that no persons, especially small
children, animals or obstacles are within the maneuvering area.
The parking assistant syst em is activated auto-
matically when reverse gear is selected and the ig-
nition is on.
Note
Be aware that the parkin g assistant system is
not switched on if the car rolls backward without
reverse gear being engaged.
Ultrasound sensors Sensors
Four ultrasound sensors in the rear bumper meas-
ure the distance to the closest obstacle.
– Range middle sensors around 60 in./150 cm
– Range outer sensors around 24 in./60 cm
Obstacles cannot be detected in the “blind” sen-
sor area (e.g. near the ground). Note
The sensors must always be kept free of dirt, ice
and snow in order to ensure that they are fully
functional.
Caution!
To avoid damaging the sensors:
f Maintain sufficient distance when cleaning with steam-jet units.
Signal tones/function
When reverse gear is selected, the parking
assistant confirms that it is switched on by issuing
a short signal tone .
A detected obstacle is signalled by an intermit-
tent tone . The intervals decrease as the obstacle
is approached.
A continuous tone sounds when the distance
becomes less than one foot. This continuous tone
c a n s t o p i f t h e o b s t a c l e i s a p p ro a c h e d c l o s e r t h a n
one foot.
The radio volume should no t be so loud as to
drown out the signal tones.

nents which you can smell. They also contain
carbon monoxide (CO), which is a colorless
and odorless gas.
Carbon monoxide can cause unconscious-
ness and even death if inhaled.
f Never start or let the engine run in an
enclosed, unventilated area.
It is not recommended to sit in your car for prolonged periods with the engine on and the

coming into contact with the exhaust pipe.
The exhaust pipe is hot when the vehicle is running
and remains hot for some time after the vehicle is
turned off.
f To prevent injury, make a point of noting where
your vehicle’s exhaust pipe is, avoid placing
your legs near the exhaust pipe, and closely
supervise children around the vehicle when the
exhaust pipe could be hot.
A hot exhaust pipe can cause serious burns.

Operation, Safety
A- Automatic speed control readiness off/on
1 -+SPEED/SET (accelerate/store)
2 -–SPEED (decelerate)
3 - OFF (interrupt)
4 -RESUMEAutomatic Speed Control The automatic speed control maintains any
selected speed between 15 mph and 145 mph
(30 km/h and 240 km/h) without you having to
use the accelerator pedal.
The automatic speed control is operated with the
lever on the steering wheel. Vehicles with PDK
Downshifts are carried out to help maintain the
pre-selected speed (especially when driving down-
hill).
Warning!
Risk of an accident resulting in serious per-
sonal injury or death. A constant speed may
not be safe in heavy traf fic, or on winding or
slippery roads.
With the speed control system engaged, the
engine speed will not return to idle when re-
moving the foot from the accelerator pedal.
f Do not use the speed co ntrol when it may be
unsafe to keep the car at a constant speed.
f Observe all local and national speed limits. Switch automatic speed control
readiness onfPress button A on the automatic speed control
lever.
Hold and store speed f Bring the car to the desired speed with the
accelerator.
f Then briefly push the operating lever forward

f Increase the speed as usual with the
accelerator.
When you ease off the accelerator, the
previously saved value is set again.
Option 2
f Push operating lever forward (position 1) until
the desired speed is reached.
The speed reached is maintained and stored
when the lever is released.
Option 3
f Push lever slightly forwards (position 1 )
(a maximum of 10 times).
The speed is increased by 1 mph (1.6 km/h),
each time the lever is pushed forwards.

Speed control operation is automatically interrupt-
ed if the speed is increased by more than approx.
16 mph (25 km/h ) for lo nger than 20 seconds.
This green indicator light in the
speedometer now indicates readiness
