i Vehicles with automatic transmis-
sion: upshifts tak eplace at higher engine
speeds after acold start .This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient .It
holds the vehicle for ashort time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot from the brake pedal to the accelerator pedal and depress it before the vehicle begins to
roll. G
WARNING
After ashort time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is arisk of an acciden tand injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not activ eif:
R you are pulling away on alevel road or a
downhill gradient
R on vehicles with automatic transmission,

thereby helps you to reduce the fuel con-
sumption and emission sofyour vehicle.

Important safety notes
G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is arisk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components. In particular, do not park on dry grassland or harvested grain fields. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect.Y ou will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is arisk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle.
! Always secure the vehicle correctly
against rolling away.O therwise, the vehicle
or its drivetrain could be damaged.
To ensure that the vehicle is safeguarded
against rolling away unintentionally:
R the parking brake must be applied
R on vehicles with manual transmission,
engage 1st gear or reverse gear
R on vehicles with automatic transmission,
the transmission must be in position Pand Parking

R that are parallel to the direction of travel
and at leas t1.0ml onger than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 mwider than your

i Note that Active Parking Assist cannot
measure the size of aparking space if it is at
right angles to the direction of travel. You
will need to judge whether your vehicle will
fit in the parking space.
When driving at speeds below 30 km/h, you
will see parking symbol ;asas tatus indi-
cator in the instrument cluster. When apark-
ing space has been detected, an arrow
towards the right or the left also appears.
Active Parking Assist only display sparking

displayed as soon as the turn signal on the
driver's side is activated. When parking on the driver's side, this must remain activated untilyou confirm the use of Active Parking Assist
by pressing the abutton on the multi-
function steerin gwheel. The system auto-
matically determines whether the parking
space is parallel or at right angles to the direc-
tion of travel.
Ap arking space is displayed while you are
driving past it, and until you are approx-
imately 15 maway from it. Parking G

General notes Traffi
cSign Assist displays the maximum
spee dpermitted and overtaking restrictions
to the drive rinthe instrument cluster. Driving
onto asection of road in the wrong direction
trigger sawarning. Traffi cSign Assist detects
traffic signs with camera system :attached
behind the top of the windscreen. The data

navigation syste mare also use dtodetermine
the current spee dlimit. If
at raffic sign that is relevant to you rvehicle
is passed, the displayoft he speedlimits and

The displayc an also be updated without a
visible traffic sign if:
R the vehicl echanges road s(e.g. motorway

R av illage or town boundary is passed which
is stored in the digital map
R the last traffic sign detected by the camera
has not been repeated
If as ign indicating the end of arestriction

The camera also detects traffic signs with a
restriction indicated by an additiona lsign
(e.g. in wet conditions).
The traffic signs are only displayed with the
restrictions if:
R the regulation must be observed with the
restriction, or
R Traffi cSign Assist is unable to determine
whether the restriction applies
If Traffi cSign Assist is unable to determine a
