Kickdown
XFor maximu macceleration, depress the
accelerator pedalb eyond the pressure point.
The automatic transmission shifts to alower
gear depending on the engine speed.
XShift back up once the desired speed is
reached.
During kickdown, you cannot shift gears using
the steering wheelp addle shifters.
If you apply full throttle, the automatic trans-
mission shifts up to the next gear when the
maximu mengine speed is reached. This pre-
vents the engine from overrevving.

In addition, they may operate vehicle equip-
ment and become trapped .There is arisko f
an accident and injury.
Whenl eaving the vehicle ,alway stake the
SmartKey with yo uand lock the vehicle .Never
leave childrenu nsupervised in the vehicle. The function of the electri
cparking brake is
dependent on the on-board voltage .Ifthe on-
board voltage is low or there is amalfunction in
the system, it may not be possible to applyt he
released parking brake.
XIf this is the case ,only park the vehicle on
level ground and secure it to prevent it rolling
away.
XShif tthe automatic transmission to position

It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is amalfunction in the system. Contact a
qualified specialist workshop.
The electri cparking brake performs afunction
test at regula rinterval swhile the engine is

Settingaspecified minimum distance
You can set the specified minimum distance for
Distanc ePilot DISTRONIC by varying the time
span between one and two seconds. With this
function, you can set the minimum distance that
Distanc ePilot DISTRONIC maintains to the vehi-
cle in front,d ependent on the vehicle speed. You
can see this distance in the multifunction dis-
play (
Ypage 145).
The specified minimum distance can be
changed while Distanc ePilot DISTRONIC is
switched on or off.
Make sure that you maintain asufficiently safe
distance from the vehicle in front.A djust the
distance to the vehicle in front if necessary.

Parking tips:
Ron narrow roads, drive as closely as possible
past the parking space
Rparking spaces that are littered or overgrown
might be identified or measured incorrectly
Rparking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly
Rsnowfall or heavy rain may lead to aparking
space being measured inaccurately
Rpay attention to the Active Parking Assist
PARKTRONIC warning messages during the
parking procedure (
Ypage 151)
Rwhen transportin gaload which protrudes
from your vehicle, you should not use Parking
Guidance
Rnever use Parking Guidance with snow chains
or an emergencys pare wheel fitted
Rmake sure that the tire pressures are always
correct. This hasadirect effect on the steer-
ing instructions
Rthe way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in fronta nd
behind it and the conditions of the location. In
some cases, Parking Guidance may guide you
too far or not far enough into aparking space.
In some cases, it may also lead you across or
ont othe curb. If necessary, cancel the park-
ing procedure with Parking Guidance.
Detecting parking spaces
