General information
Position of switch: 0,
,
If the driver door is opened with the ignition
switched off, the exterior lighting is automati‐
cally switched off at these reel settings.
Parking lights
Position of switch
: the vehicle's lights
light up on all sides, e.g., for parking.
Do not use the parking lights for extended pe‐
riods; otherwise, they might drain the battery
and it would then be impossible to start the en‐
gine.
When parking, it is preferable to reel on the
one-sided roadside parking lights, refer to
page 103.
Low beams Position of switch
with the ignition
switched on: the low beams light up.
Welcome lights
When parking the vehicle, leave the reel in po‐
sition
or : the parking and interior
lights light up briefly when the vehicle is un‐
locked.

System limits
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported though tire inflation pressures are
correct.
The tire inflation pressure depends on the
tire's temperature. Driving or exposure to the
sun will increase the tire's temperature, thus
increasing the tire inflation pressure. The tire
inflation pressure is reduced when the tire
temperature falls again. These circumstances
may cause a warning when temperatures fall
very sharply.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire inflation pressure can be de‐
tected.
Display in the following situations:▷A wheel without TPM electronics is fitted:
have the service center check it if needed.▷Malfunction: have the system checked by
your service center.▷TPM was unable to complete the reset.
Reset the system again.▷Interference through systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the
level to trigger illumination of the TPMS low
tire pressure telltale. Your vehicle has also
been equipped with a TPMS malfunction indi‐
cator to indicate when the system is not oper‐
ating properly. The TPMS malfunction indica‐
tor is combined with the low tire pressure
telltale. When the system detects a malfunc‐
tion, the telltale will flash for approximately one
minute and then remain continuously illumi‐
nated. This sequence will continue upon sub‐
sequent vehicle start-ups as long as the mal‐
function exists. When the malfunction indicator
is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace‐
ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning prop‐
erly. Always check the TPMS malfunction tell‐
tale after replacing one or more tires or wheels
on your vehicle to ensure that the replacement
or alternate tires and wheels allow the TPMS
to continue to function properly.Seite 113SafetyControls113

Automatic deactivation during forward
travel
The system switches off when a certain driving
distance or speed is exceeded.
Switch the system back on if needed.
With front PDC: switching on/off
manually
Press button.▷On: the LED lights up.▷Off: the LED goes out.
The rearview camera image is displayed when
the reverse gear is engaged by pressing the
button.
Display
Signal tones When approaching an object, an intermittent
sound indicates the position of the object. E. g.
if an object is detected to the left rear of the
vehicle, a signal tone sounds from the left rear
speaker.
The shorter the distance to the object, the
shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
With front PDC: if objects are located both in
front of and behind the vehicle, an alternating
continuous signal is sounded.
An interval tone is interrupted with the appro‐
priate equipment after about 3 seconds:
▷If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.▷If moving parallel to a wall.
The signal tone is switched off:
▷When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.▷When selector lever position P is engaged
on vehicles with Steptronic transmission.
Volume
The volume of the PDC signal tone can be ad‐
justed similar to the sound and volume set‐
tings of the radio.
Settings are stored for the profile currently in
use.
Visual warning
The approach of the vehicle to an object can
be shown on the Control Display. Objects that
are farther away are already displayed on the
Control Display before a signal sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.
The range of the sensors is represented in the
colors green, yellow and red.
When the image of the rearview camera is dis‐
played, the reel can be made to PDC:

Residual cooling
When the automatic climate control has re‐
duced the interior temperature, this tempera‐
ture can be maintained after the engine has
been switched off. This function can be acti‐
vated up to 15 minutes after the engine is
switched off and for a maximum period of 6 mi‐
nutes.
Functional requirement▷The high-voltage battery is sufficiently
charged.▷External temperature at least ap‐
prox. 59 ℉/15 ℃.
