Driving and operating151Manual transmission
To engage reverse on 6-speed
transmission, depress the clutch
pedal, pull the ring under the selector
lever and move the selector lever
quite to the left and front.
If the gear does not engage, set the
selector lever to neutral, release the
clutch pedal and depress again. Then
repeat gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
When clutch slip is detected for a specific time, the engine power will be reduced. A warning is displayed in the
Driver Information Centre. Release
the clutch.Caution
It is not advisable to drive with the hand resting on the selector lever.
Gear shift indication 3 97.
Stop-start system 3 140.
Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator m 3 96.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
154Driving and operatingDeactivation of automatic operation1. Start the engine.
2. If the parking brake is released, apply the parking brake pulling the
switch m.
3. Take your foot off the brake pedal.
4. Press the switch m for at least
10 s and maximum 15 s.
5. Release the switch m.
6. Press and hold the brake pedal. 7. Pull the switch m for 2 s.
The deactivation of the automatic
operation of the electric parking brake
is confirmed by o illuminating in the
instrument cluster 3 96. The electric
parking brake can only be applied and released manually.
To reactivate the automatic
operation, repeat the steps described
above.
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 3 105.
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.
Brake assist If brake pedal is depressed quickly
and forcefully, maximum brake force
is automatically applied.Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance
when depressing the brake pedal.
Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain
on for further two seconds. The
brakes release automatically as soon
as the vehicle begins to accelerate.
170Driving and operatingIf a vehicle directly ahead is
approached too quickly, a warning
chime and alert in the Driver
Information Centre is provided.9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
Activation
Forward collision alert detects
vehicles and operates automatically
at all speeds between 5 km/h and 140 km/h.
Alerting the driver
The driver is warned by following
alerts:
● Symbol , illuminates and a
warning message is displayed in
the Driver Information Center,
when the distance to the vehicle
ahead gets to small.
● Symbol , illuminates, a warning
message is displayed in the
Driver Information Center and a
warning chime sounds, when a
collision is imminent and
immediate driver's action is
required.9 Warning
Forward collision alert is just a
warning system and does not

The colour lighting of this control
indicator does not correspond to
local traffic laws on following
distance. The driver bears full
responsibility for maintaining safe
following distance according to
applicable traffic rules, weather
and road conditions etc. at all
times.
Selecting the alert sensitivity
7'' Colour Info Display: Adjust the alert
sensitivity in the vehicle
personalisation 3 106.
Driving and operating1718'' Colour Info Display: Adjust the alert
sensitivity in the settings of the active
safety brake in the vehicle
personalisation 3 106.
The chosen setting will remain until it
is changed. The alert timing will vary
based on vehicle speed. The faster
the vehicle speed, the farther away
the alert will occur. Consider traffic
and weather conditions when
selecting the alert timing.
Deactivation The system can only be deactivated
by deactivating the active emergency braking in the vehicle personalisation
3 106.
System limitations Forward collision alert is designed to
warn on vehicles only, but may react also to other objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● driving on winding or hilly roads
● driving during nighttime● weather limits visibility, such as fog, rain, or snow
● the sensor in the windscreen or the radar unit behind the front
bumper are blocked by snow, ice,
slush, mud, dirt etc.
● the windscreen is damaged or affected by foreign objects, e.g.
stickers
Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles, pedestrians
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 3 169 or the front pedestrian
protection alert 3 174.
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 to
animals. After a sudden lane
change, the system needs a
certain time to detect the next
preceding vehicle.
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
Operation conditions
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 and
front camera active emergency
braking operates in forward gear in
the range between walking speed
and 140 km/h.
172Driving and operatingActivation
A precondition is that forward collision
alert with front camera system is not
deactivated in the vehicle
personalisation menu 3 106.
Functionality
The system includes: ● brake preparation system
● emergency automatic braking ● forward looking brake assist
● intelligent brake assist (only with radar sensor)
● forward collision alert
● front pedestrian protection
Brake preparation system
When approaching a vehicle ahead
or a pedestrian so quickly that a
collision is likely, the brake
preparation system slightly
pressurises the brakes. This reduces
the response time when a braking is
required.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. If active emergency
braking is applied, m flashes in the
instrument cluster. Depending on the
situation, the vehicle may
automatically brake moderately or
hard. This front automatic braking can
only occur if a vehicle ahead is
detected 3 169 . On vehicles with front
pedestrian protection, front automatic
braking can also occur when a
pedestrian ahead is detected 3 174.
Emergency automatic braking may
slow the vehicle to a complete stop to try to avoid a potential crash. If this
happens, emergency automatic
braking may engage the electric
parking brake to hold the vehicle at a
stop. To release press the electric
parking brake button or firmly press
the accelerator pedal.9 Warning
Emergency automatic braking is
an emergency crash preparation
feature and is not designed to
avoid crashes. Do not rely on the
system to brake the vehicle.
Emergency automatic braking will
not brake outside of its operating speed range and only responds to
detected vehicles and
pedestrians.
Forward looking brake assist
In addition to the brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. Therefore, pressing
the brake pedal less strongly results
in immediate hard braking. This
function helps the driver brake
quicker and harder before the
imminent collision.
Driving and operating1739Warning
Active emergency braking is not
designed to apply hard
autonomous braking or to
automatically avoid a collision. It is designed to reduce the vehicle
speed before a collision. It may not
react to animals. After a sudden
lane change, the system needs a
certain time to detect the next
preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the brakes and steer to avoid
collisions.
The system is designed to work with
all occupants wearing their seat belts.
Intelligent brake assist
If the vehicle is equipped with radar
sensor, intelligent brake assist may
be available. Intelligent brake assist
provides a boost to braking when the
brake pedal is quickly applied. The
braking is based on the speed of
approach and distance to a vehicle
ahead.
Minor brake pedal pulsations or pedal movement during this time is normal
and the brake pedal should continue to be applied as needed. Intelligent
brake assist will automatically
disengage only when the brake pedal is released.9 Warning
Intelligent brake assist may
increase vehicle braking in
situations when it may not be
necessary. You could block the
flow of traffic. If this occurs, take
your foot off the brake pedal and
then apply the brakes as needed.
Forward collision alert 3 169.
Front pedestrian protection 3 174.
Deactivation Active emergency braking can be
deactivated in the personalisation
menu 3 106. If deactivated, m
illuminates in the instrument cluster
and a warning message is displayed
in the Driver Information Centre.
We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when towing a trailer or caravan
● when carrying long objects on roof bars or a roof rack
● when the vehicle is being towed with the engine running
● when a spare wheel is fitted that is smaller than the other wheels
● before using an automatic car wash with the engine running
● before placing the vehicle on a rolling road in a workshop
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
● if the brake lamps are not working
