Driving and operating173Manual mode
To utilise the engine braking effect, select a lower gear in good time when
driving downhill. Changing into
manual mode is only possible while the engine is running or during an
Autostop.
Rocking the vehicle Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector
lever between R and D in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
The most recently engaged gear (see
transmission display) remains
engaged when switching off ignition.
With N, no gear is engaged.
Therefore always apply the parking
brake when switching off ignition. If
parking brake is not applied, P flashes
in the transmission display and the
key cannot be removed from the
ignition switch. P stops flashing in the
transmission display as soon as the
parking brake is slightly applied.When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
Emergency operation to avoid
freezing of the parking brake 3 164.
Manual mode If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, the
shift is not executed. This prevents
the engine from running at too low or
too high an engine speed. A warning
message is displayed in the Driver
Information Centre. Vehicle
messages 3 122.
If engine speed is too low, the transmission automatically shifts to a
lower gear.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.
Gear shift indication
The symbol R or S with a number
beside is indicated when gearshifting
is recommended for fuel saving
reasons.Shift indication appears only in
manual mode.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● The adaptive programme tailors gearshifting to the driving
conditions, e.g. greater load or
gradients.
Kickdown If the accelerator pedal is pressed
down completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.
Fault
To prevent damage to the manual transmission automated, the clutch is
engaged automatically at high clutch
temperatures.
176Driving and operating3 110. The electric parking brake
operates automatically with
adequate force.
Before leaving the vehicle, check
the electric parking brake status.
Control indicator m 3 110.
The electric parking brake can always
be activated, even if the ignition is off.
Do not operate electric parking brake
system too often without engine
running as this will discharge the
vehicle battery.
Releasing
Switch on ignition. Keep foot brake
pedal depressed and then push
switch m.
Drive away function
Vehicles with manual transmission:
Depressing the clutch pedal and then
slightly releasing the clutch pedal and slightly depressing the accelerator
pedal releases the electric parking
brake automatically. This is not
possible when switch m is pulled at
the same time.
Vehicles with automatic transmission
or manual transmission automated:
Engaging D and then depressing the
accelerator pedal releases the
electric parking brake automatically.
This is not possible when switch m is
pulled at the same time.
Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, the electric
parking brake system will decelerate
the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Automatic applying
If the vehicle is equipped with
automatic transmission and adaptive
cruise control is active, electric
parking brake is applied automatically when vehicle is stopped by the
system for more than two minutes.
Parking brake releases automatically
after moving off.Functionality check
When the vehicle is not moving, the
electric parking brake might be
applied automatically. This is done to
check the system.
Fault
Failure mode of electric parking brake
is indicated by a control indicator j
and by a vehicle message which is
displayed in the Driver Information
Centre. Vehicle messages 3 122.
Apply electric parking brake: pull and
hold the switch m for more than
five seconds. If control indicator m
illuminates, electric parking brake is
applied.
Release electric parking brake: push and hold the switch m for more than
two seconds. If control indicator m
extinguishes, electric parking brake is
released.
Control indicator m flashes: electric
parking brake is not fully applied or
released. When continuously
flashing, release electric parking
brake and retry applying.
Driving and operating179Deactivation
ESC and TC can be deactivated:● hold b pressed for a minimum of
five seconds: ESC and TC are
both deactivated. k and n
illuminate and status messages appear in the Driver Information
Centre.
● To deactivate only Traction control system press button b
briefly: TC is inactive but ESC
remains active, k illuminates. A
status message appears in the
Driver Information Centre when
TC is deactivated.
ESC is reactivated by pressing the
b button again. If the TC system was
previously disabled, both TC and
ESC are reactivated. k and n
extinguishes when TC and ESC are
reactivated.
ESC is also reactivated the next time
the ignition is switched on.
Fault
If there is a fault in the system the
control indicator b illuminates
continuously and a message appears in the Driver Information Centre. The
system is not operational.
Have the cause of the fault remedied
by a workshop.
Sport mode
Sport mode adapts the settings of
some vehicle systems to a sportier
driving style.
● The engine reacts more quickly to the accelerator pedal.
● Steering reacts more direct to provide better contact with the
road surface.
● Shift points of automatic transmission occur later.
● Control modes of adaptive cruise
control are adapted to more
sportive settings.
Driving and operating195Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles and obstacles
directly ahead, when a collision can no longer be avoided either by
manual braking or by steering. Before the active emergency braking
applies, the driver is warned by the
forward collision alert 3 191.
The feature uses various inputs (e.g.
camera sensor, radar sensor, brake
pressure, vehicle speed) to calculate
the probability of a frontal collision.9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only to reduce
the vehicle speed before a
collision.
The system may not react for
pedestrians or animals. After a
sudden lane change, the system
needs a certain time to detect the
next preceding vehicle.
The driver shall always be ready to take action and apply the brakes
and steer to avoid collisions.
Functionality
If equipped only with front camera the active emergency braking operates in
forward gear above walking speed up to 85 km/h.
With radar sensor active emergency
braking operates in forward gear
above walking speed at all speeds.
A precondition is that forward collision
alert with front camera system is not
deactivated by pressing V on the
steering wheel 3 191or, with radar
sensor, that it is not deactivated in the
vehicle personalisation menu 3 123.
The system includes: ● brake preparation system
● emergency automatic braking
● forward looking brake assist
● intelligent brake assist (only with radar sensor)
Brake preparation system
When approaching a vehicle ahead
so quickly that a collision is likely, the brake preparation system slightlypressurizes the brakes. This reduces
the response time, when a manual or automatic braking is requested.
The brake system is prepared so that
braking can occur more rapidly.
If equipped only with front camera the system operates up to a speed of 80
km/h.
Emergency automatic braking After activation of brake preparation
system and just before the imminent
collision, this function automatically
applies limited braking to reduce the
impact speed of the collision or
prohibit a crash. Depending on the
situation, the vehicle may
automatically brake moderately or
hard. This front automatic braking can
202Driving and operating
When searching for a parking slot, the
system is ready to operate with a
short press of (.
The system recognises and
memorises ten metres for parallel
parking slots or six metres for
perpendicular parking slots in the
parking assist mode.
The system can only be activated at
a speed up to 30 km/h and the system searches for a parking slot at a speed
up to 30 km/h.
The maximum allowed parallel
distance between the vehicle and a
row of parked cars is 1.8 metres for
parallel parking and 2.5 metres for
perpendicular parking.
FunctionalityParking slot searching mode,
indication in the Driver Information
Centre
Select parallel or perpendicular
parking slot in Driver Information
Centre by long press on (.
The system is configured to detect parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
signal indicator on the driver side.
When a slot is detected, a visual
feedback in the Driver Information
Centre and an acoustic signal is
given.
