Automatic deactivation
In certain situations, the Auto Start/Stop func‐
tion is deactivated automatically in the interest
of safety, for example if the driver's absence is
detected.

Parking brake The concept
Your vehicle is equipped with an electrome‐
chanical parking brake that can be set and re‐
leased by using a switch.
The parking brake is primarily used to prevent
the vehicle from rolling when it is parked.
When the vehicle is stationary, the parking
brake acts on the rear wheels via an electro‐
mechanical mechanism. When the vehicle is
rolling or being driven, the parking brake acts
on the disc brakes of the front and rear wheels
via the hydraulic brake system.
Setting
Pull the switch. The parking brake is set. The indicator lamp in the instrument
cluster and the LED on the switch light
up red. The parking brake is set.
Indicator light in Canadian models.
To set the parking brake, the remote control
does not need to be in the ignition lock.
While driving
If exceptional circumstances should make it
necessary to engage the parking brake while
the vehicle is in motion, pull the switch for an
extended period: the vehicle brakes forcefully
while the switch is being pulled.
The indicator lamp in the instrument
cluster lights up red, a sound is issued
and the brake lights light up.
Indicator light in Canadian models.
When the vehicle is braked almost to a halt, ap‐
prox. 2 mph/3 km/h, the parking brake remains set.
Releasing Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, for exam‐
ple, cannot start the engine or release the
parking brake.◀
The parking brake can only be released while
the ignition is switched on or the engine is run‐
ning.Seite 59DrivingControls59

The transmission provides assistance in the
following situations:▷Upshifts and downshifts are executed only
when they will result in a feasible combina‐
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by
the system.▷When the vehicle stops, the transmission
automatically shifts down to first gear.▷Shortly before the vehicle slows down to
below the minimum speed of the gear cur‐
rently engaged, the transmission automati‐
cally shifts down without requiring your in‐
tervention.
Shifting down rapidly: even in manual mode,
you can skip several gears to achieve optimal
acceleration. Do so by pressing the accelerator
past the resistance point.
Changing to Drive mode Push the selector lever to the right.
Shifting gears via the selector lever
In manual mode:
▷To shift up, pull back the selector lever.▷To shift down, push it forward.
Shifting gears using the shift paddles
on the steering wheel
The shift paddles allow you to shift gears with‐
out taking your hands off the steering wheel.
You do not need to raise your foot from the ac‐
celerator when doing so.
▷Shift up: pull right shift paddle.▷Shift down: pull left shift paddle.
Gears can be shifted using the shift paddles in
Drive mode or in manual mode.
Gear change in manual mode
When manual mode is active, refer to page 67,
gears can be changed using the shift paddles
or the selector lever.
Gear change in Drive mode The shift paddles can be used to change gears
in Drive mode as well.
Afterwards, if the shift paddles are not used for
some time and vehicle acceleration is insuffi‐
cient, the forward gears are changed again au‐ tomatically.
Launch Control
Launch Control enables you to drive off with an
optimal vehicle acceleration on a high grip road
surface.
Do not use Launch Control too often
Do not use Launch Control too often, as
the higher loads on the vehicle lead to prema‐
ture component wear.◀
Launch Control is available when the engine is
at operating temperature, i.e., after driving con‐
tinuously for at least 6 miles/10 km.
1.With the engine running, depress the brake
pedal with your left foot.2.Activate the SPORT+ program of the Dy‐
namic Driving Control, refer to page 100.3.With the vehicle stationary, activate manual
mode and select first gear.4.Press the accelerator all the way down.
The engine speed when driving off is con‐
trolled. A flag symbol appears in the instru‐
ment cluster.Seite 68ControlsDriving68

such as the following, and driver intervention
may be necessary:
▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings.▷In tight curves, on hilltops or in depres‐
sions, in cross traffic or half-obscured on‐
coming traffic on freeways.▷In poorly-lit towns and cities and in the
presence of highly reflective signs.▷At low speeds.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.

tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐

Actions in the event of a flat tire Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
Run-flat tires
You can continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at
the next opportunity.
If the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx.
50 miles/80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e. g., curbs, potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending on the driving speed, road
conditions, external temperature, cargo load,
etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering
properties.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of the tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving, and contact your service
center.◀
Tire Pressure Monitor TPMThe concept

ing if there is a significant loss of pressure inSeite 94ControlsSafety94

After a short trip at over 30 km/h, the set tire
inflation pressures are adopted as target val‐
ues. The system reset is completed as you
drive, and can be interrupted at any time.
When driving resumes, the reset is continued
automatically. On the Control Display, the tires
are shown in green and "TPM active" is dis‐
played again.

sures, all tires on the Control Display are dis‐

Message when not reset
The warning light lights up yellow. A
Check Control message is displayed.
The system may not have been reset
although a wheel was changed.
Check the tire inflation pressure and reset the
system, refer to page 95.
System limits
The system does not function properly if it has
not been reset, e.g., it may identify a tire as flat
in spite of the fact that the tire is filled to the
correct inflation pressure.
The tire pressure depends on the temperature
of the tire. An increase in the tire temperature,
e.g., while driving or due to sunlight, increases
the tire inflation pressure. The tire pressure
decreases when the tire temperature drops. In
case of severe temperature drops, this behav‐ ior may lead to a warning on account of the de‐
fined warning limits.
Malfunction The small warning light flashes in yel‐
low and then lights up continuously;
