dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a slope, turn the
front wheels in the direction of the curb.▷On uphill grades or on a slope, also secure
the vehicle, for example with a wheel

Auto Start/Stop function
The concept
The Auto Start/Stop function helps save fuel.
The system switches off the engine during a
stop, for example, in traffic congestion or at
traffic lights. The ignition remains switched on.
The engine starts again automatically for driv‐
ing off.
Information After every start of the engine using the Start/
Stop button, the Auto Start/Stop function is in
the last selected state, refer to page 66. When
the Auto Start/Stop function is active, it is avail‐
able when the vehicle is traveling faster than
about 3 mph, approx. 5 km/h.
Depending on the selected driving mode, refer
to page 118, the system is automatically acti‐
vated or deactivated.

The Chrono package consists of three display
instruments in the cockpit, where the engine oil
pressure, the turbocharger boost, and the time
are displayed. In addition, intermediate and to‐
tal times can be measured using the stop
watch.
The display elements of the Chrono package
mainly support a sporty driving style, e,g, on
racetracks.

A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
A vehicle with a damaged tire reacts differently,
e.g., it has reduced lane stability during brak‐
ing, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering ma‐
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be shorter or longer de‐
pending on the driving speed, road conditions,
external temperature, cargo load, etc.
WARNING
Your vehicle handles differently when a
run-flat tire is damaged and has low or missing
tire inflation pressure, for example, your lane
stability is reduced when braking, braking dis‐
tances are longer and the self-steering proper‐
ties will change. There is risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h. ◀
Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of
the tire could come loose and cause an acci‐
dent.
Do not continue driving. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Intelligent Safety
The concept
Intelligent Safety enables central operation of
the driver assistance system.
The intelligent safety systems can hel prevent
an imminent collision.▷Front-end collision warning with City Brak‐
ing function, refer to page 110.▷Person warning with City light braking func‐
tion, refer to page 113.
Information
WARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to system
limits, warnings or reactions of the system may
not be output or they may be output too late or
incorrectly. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations. ◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated, for example approach control warning with
light braking function. There is risk of an acci‐
dent. Switch all Intelligent Safety systems off
prior to tow-starting/towing. ◀

SymbolMeasureSymbol lights up red: prewarning.
Brake and increase distance.Symbol flashes red and an acoustic
signal sounds: acute warning.
You are requested to intervene by
braking or make an evasive maneu‐
ver.
Prewarning
This warning is issued, for example, when there
is the impending danger of a collision or the
distance to the vehicle ahead is too small.
The driver must intervene actively when there is a prewarning.
Acute warning with braking function
Acute warning in displayed in case of the immi‐
nent danger of a collision when the vehicle ap‐
proaches another object at a high differential
speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking inter‐
vention in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Braking intervention The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Premise for the brake booster
is sufficiently quick and sufficiently hard step‐
ping on the brake pedal. The system can assist
with some braking intervention if there is risk of
a collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: During a braking inter‐
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if DSC
Dynamic Stability Control is switched on.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by actively
moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
System limits
Information WARNING
The system can react incorrectly or not at
all due to the system limits. There is risk of acci‐
dents or risk of property damage. Observe the
system limits and actively interfere if needed. ◀
Detection range The system's detection potential is limited.
Thus a system reaction might not come or
might come late.
E. g. the following situations may not be de‐
tected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you, or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the field of view of the camera or the
front windshield are dirty or covered.▷If the driving stability control systems are
deactivated, for example DSC OFF.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.Seite 112CONTROLSSafety112
