Automatic transmission
Driving tips
Accelerator position
Your driving style influences the automatic
transmission’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
Press the accelerator past the point of
resistance.
Depending on the engine speed the au-
tomatic transmission shifts into a lower
gear.
Ease on the accelerator when you have
reached the desired speed.
The automatic transmission shifts up
again.Stopping
When you stop briefly, e.g. at traffic lights:
Leave the automatic transmission in
gear.
Hold the vehicle with the brake.
When you stop for a longer period of time
with the engine idling and/or on a hill:
Set the electric parking brake.
Shift into park positionP.
Maneuvering
When you maneuver in tight areas,
e.g. when pulling into a parking space:
Control the vehicle speed by gradually
releasing the brakes.
Accelerate gently.
Never abruptly step on the accelerator.Rocking the vehicle
Rocking the vehicle by shifting between
drive positionD and reverse gearR can
help free a vehicle stuck in mud or snow.
The engine control system of this vehicle
electronically limits shifting between drive
positionD and reverse gearR to very low
speeds (i.e. approx. 5 mph (9 km/h)). To
shift between drive positionD and reverse
gearR, move the gear selector lever past
the resistance point up or down.
Working on the vehicle
Warning!
G
When working on the vehicle, set the
electric parking brake and shift to park
positionP. Otherwise the vehicle could roll
away.
388 Controls in detailDriving systemsWhen DISTRONIC Plus detects a vehicle
driving ahead of you, the ring on the speed-
ometer dial lights up between the speed of
the vehicle ahead of you and set speed2.
If DISTRONIC Plus calculates that there is
a danger of collision (
page 397):
The distance warning lampl in the
instrument cluster comes on.
An intermittent warning sounds.
Immediately brake the vehicle to avoid
a collision.
Under no circumstances should the
driver await the intermittent warning
sound before braking. See the follow-
ing warning note.
The intermittent warning sound ceases
and the distance warning lampl
goes out when the necessary distance
to the vehicle ahead is again
established.
Warning!
G
An intermittent warning sounds and the dis-
tance warning lampl in the instrument
cluster is illuminated if the DISTRONIC Plus
system calculates that the distance to the
vehicle ahead and your vehicle’s current
speed indicate that DISTRONIC Plus will not
be capable of slowing the vehicle sufficiently
to maintain the preset following distance,
which creates a danger of a collision.
Immediately brake your vehicle to increase
the distance between your vehicle and the
vehicle in front of you. The warning sound is
intended as a final caution that you have not
interceded with your own braking inputs to
avoid a potentially dangerous situation. Do
not wait for the operation of the warning sig-
nal to intercede with your own braking, as
that will result in potentially dangerous
emergency braking which will not always re-
sult in an impact being avoided.
Tailgating increases the risk of an accident.
Warning!
G
DISTRONIC Plus brakes your vehicle with a
maximum of 13 ft/s
2 (4 m/s
2). This corre-
sponds to about 40% of the maximum decel-
eration ability of your vehicle.
DISTRONIC Plus brakes the vehicle in an ef-
fort to restore the preset distance or to
maintain the speed. The brake pedal is auto-
matically applied as this happens which re-
sults in the brake pedal moving.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the DISTRONIC Plus sys-
tem.
Do not place your foot under the brake pedal
– your foot could become caught.

Each warning indicator is divided into five
yellow and two red distance segments for
either side of the vehicle.
If yellow indicators 3 under the segments
are lit, Park Assist is ready to measure.The position of the gear selector lever de-
termines which warning indicators will be
activated.
As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the sev-
enth distance segment illuminates, you
have reached the minimum distance.
Front area:
As soon as the first red segment lights
up, you will hear an intermittent warn-
ing tone for approx. two seconds. Once
the second red segment lights up, you
will hear a continuous warning tone.
You have reached the minimum dis-
tance.
Rear area:
As soon as the first red segment lights
up, you will hear an intermittent warn-
ing tone for approx. two seconds. Once
the second red segment lights up, you
will hear a continuous warning tone.
