Driving and operating159ABS starts to regulate brake pressure
as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
Control indicator u 3 102.
Fault
If control indicators u and j
illuminate with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre, there is a fault in
the ABS. The brake system remains
operational but without ABS
regulation.9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
If control indicators u, j , R and
C illuminate, the ABS and ESP are
deactivated and the message
BRAKING FAULT is shown in the
Driver Information Centre. Seek the
assistance of a workshop.
Have the cause of the fault remedied
by a workshop.
Parking brake9 Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
brake pedal at the same time.
160Driving and operatingControl indicator R 3 102.
Parking 3 143.
Retractable parking brake
Depending on vehicle, the parking
brake lever retracts to the horizontal
position even with the parking brake
applied.
To release the parking brake, press the release button and pull the lever
up slightly, then return the lever to the
horizontal position.
To apply the parking brake, pull the
lever up then release it. The lever
returns to the horizontal position.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Brake assist is not available during an
Autostop.
Stop-start system 3 140.
Hill start assist
The system helps prevent unintended movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline (with the
selector lever in a forward gear or
reverse gear), the brakes remain on
for a further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.Caution
The Hill start assist cannot
completely prevent vehicle
movement in all situations
(extremely steep gradients, etc.).
If necessary, depress the brake
pedal to prevent the vehicle from
rolling backwards.
The Hill start assist is not active
during an Autostop.
Stop-start system 3 140.
168Driving and operatingOperation conditions
The system is operational at a vehicle
speed between 15 km/h and
100 km/h.
Activation The system is automatically activewhen the ignition is switched on.
Functionality
When driving in the speed range
mentioned above and a risk of
collision with the vehicle ahead is
imminent, l will flash and a warning
chime sounds.
The indicator light l and the chimes
stop when the system detects that a
collision is not imminent anymore.
Just before the imminent collision, the
system brakes automatically to
reduce the impact speed of the
collision or prohibit a crash.9 Warning
Do not rely on the system to brake
the vehicle. Active emergency
braking will not brake outside of its
operating speed range and only
responds to detected vehicles.
Deactivation and re-activation
Active emergency braking can be
deactivated with the vehicle
stationary and the ignition switched
on:
Toggle through the Driver Information Centre with the buttons on the right
stalk tip until message AEBS
ACTIVE appears.
To deactivate the system, press and
hold one of the two buttons for
approx. 3 seconds. Message AEBS
DEACTIVATED is displayed and l
illuminates in the instrument cluster until system is re-activated again.
To re-activate the system, press and hold one of the two buttons for
approx. 3 seconds. Message AEBS
ACTIVE is displayed and l
disappears.
Vehicle messages 3 107.
We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when the vehicle is being towed
● before using an automatic car wash with ignition switched on
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
Driving and operating169Conditions for re-activation
The Active emergency brake system
can only be re-activated if:
● the gear lever is not in neutral
● parking brake is not activated
● vehicle is not cornering
System limitations In some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs
in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
service. Firmly apply the accelerator
pedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is
limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime
● sensor in the windscreen or radar
unit behind the front bumper
blocked by snow, ice, slush, mud, dirt, etc.
● windscreen damaged or affected
by foreign objects, e.g. stickers
Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.
Fault
In case the system requires a service,
a message is displayed in the Driver
Information Centre.
Additionally, warning lights l and j
illuminate at the same time.
When the system detects that its
function is not available, warning
lights l or j illuminates and stays
on. Additionally, a message in the
Driver Information Centre appear.
The system may be temporarilydisrupted (for example: radar or
camera obscured by dirt, mud, snow
etc.). In this case,park the vehicle and switch off the engine. Clean the
windscreen area around the camera
and the detection zone of the radar in the front bumper. When the warning
lights and messages still appear after
starting the vehicle again, seek the
assistance of a workshop.
Parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The parking assist measures the
distance between the vehicle and
obstacles behind the vehicle. It
informs and warns the driver by giving acoustic signals.
Driving and operating177Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust fitting of towing equipment at
a later date to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Driving characteristics and towing tips
In the case of trailers with brakes,
attach the breakaway stopping cable.
Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce
snaking movements. For trailers with
low driving stability the use of a
stabiliser is recommended.
A maximum speed of 80 km/h must
not be exceeded, even in countries
where higher speeds are permitted.If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 252.
Trailer towing
Trailer loads The permissible trailer loads are
vehicle-dependent and engine-
dependent maximum values which
must not be exceeded. The actual
trailer load is the difference between
the actual gross weight of the trailer
and the actual coupling socket load
with the trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In
general, they are valid for gradients
up to max. 12%.
The permitted trailer load applies up to the specified incline and up to an
altitude of 1000 m above sea level.Since engine power decreases as
altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 m of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than 8%, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 231.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load is specified on the
towing equipment identification plate
and in the vehicle documents. Always aim for the maximum load, especially in the case of heavy trailers. The
vertical coupling load should never
fall below 25 kg.
178Driving and operatingIn the case of trailer loads of
1200 kg or more, the vertical coupling load should not be less than 50 kg.
Rear axle load When the trailer is coupled and the
towing vehicle fully loaded (including all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Towing equipment audible
warning
For vehicles fitted with towing
equipment, when connected to a
trailer the pitch of the audible warning
changes upon operation of the turn
lights.
The pitch of the audible warning will
change if a turn light on the trailer or
the towing vehicle fails.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While the system is working,keep steering wheel as still as
possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Program (ESP) 3 162.Auxiliary features
Power take-off
Activation
To activate the power take-off, with
the vehicle stationary and the engine
idling:
● Set the gearshift lever to neutral (vehicles with manual
transmission automated:
selector lever in position N).
● Depress the clutch pedal.
