Driving and operating149In the event of a fault, control indicator
g illuminates. Additionally, a
warning message is displayed in the
Driver Information Centre.
Vehicle messages 3 103.
Continued driving is restricted or not
possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.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 R 3 93.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS 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.
After starting-off the system performs a self-test which may be audible.
Control indicator u 3 93.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.
Driving and operating1719Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:
● vehicles outside the side blind zones which may be rapidly
approaching
● pedestrians, cyclists or animals
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn light.
When the system detects a vehicle in the side blind zone while driving
forward, either while passing a
vehicle or being passed, a yellow
warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn light, the warning symbol B starts flashing
yellow as a warning not to change
lanes.
Note
If the overtaking vehicle is at least
10 km/h faster than the vehicle being
overtaken, the warning symbol B in
the relevant exterior mirror may not
illuminate.
Side blind spot alert is active from
speeds of 10 km/h up to 140 km/h.
Driving faster than 140 km/h
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the speed again will extinguish the
warning symbols. If a vehicle is then
detected in the blind zone, the
warning symbols B will illuminate as
normal on the relevant side.
When the vehicle is started, both exterior mirror displays will briefly
illuminate to indicate that the system
is operating.
The system can be activated or
deactivated in the Info Display.
Vehicle personalisation 3 106.
Deactivation is indicated by a
message in the Driver Information
Centre.
Detection zones
The detection zones start at the rear bumper and extend approx. 3 m
rearwards and to the sides. The
height of the zone is approx. between 0.5 m and 2 m off the ground.
The system is deactivated if the
vehicle is towing a trailer.
Side blind spot alert is designed to ignore stationary objects, e.g.
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.
Driving and operating173The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Warning symbols
Warning symbols are indicated as
triangles 9 on the picture, which show

Fault messages are displayed with a 9 on the top line of the Info Display.
The rear view camera may not
operate properly when:
● The surrounding is dark.
● The sun or the beam of headlights is shining directly into
the camera lens.
● Ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth.
● The vehicle is towing a trailer.
● The vehicle had a rear end accident.
● There are extreme temperature changes.Traffic sign assistant
Functionality
The traffic sign assistant system
detects designated traffic signs via a
front camera and displays them in the
Driver Information Centre.
Traffic signs, which will be detected,
are:
Limit and no passing signs ● speed limit
● no passing
● end of speed limit
● end of no passing
174Driving and operatingRoad signs
Beginning and end of:
● city regions (country-specific)● motorways
● A-roads
● play streetsAdd-on signs ● additional hints to traffic signs
● restriction of trailer towing
● tractor constraints
● wet warning
● ice warning
● direction arrows
Speed limit signs and no passing
signs are displayed in the Driver
Information Centre until the next
speed limit sign or end of speed limit is detected or up to a defined sign
timeout.Indication of multiple signs on the
display is possible.
An exclamation mark in a frame
indicates that there is an additional
sign detected which cannot be clearly
identified by the system.
The system operates without loss of
performance up to a speed of
200 km/h depending on the lighting
conditions. At night the system is
active up to a speed of 160 km/h.
As soon as vehicle speed becomes
slower than 55 km/h, the display will
be reset and the content of the traffic
sign page will be cleared, e.g. when
entering a city zone. The next
recognized speed indication will be
displayed.
Display indication
Information about the currently valid
traffic signs is available on the
designated traffic sign assistant page in the Driver Information Centre.
Additionally, the currently valid speed
limit is displayed permanently in the
lower line of the Driver Information
Centre. In case a speed limit with add-
on is available, a + symbol is
displayed in this area.

Due to the system design, an
escape of liquid gas after
releasing the locking lever is
unavoidable. Avoid inhaling.
9 Warning
The liquid gas tank should only be
filled to 80% capacity, for safety
reasons.
The multivalve on the liquid gas tank
automatically limits the fill quantity. If
a larger quantity is added, we
recommend not exposing the vehicle
to the sun until the excess amount
has been used up.
Fuel filler cap
Only use genuine fuel filler caps. Diesel-engined vehicles have special fuel filler caps.
Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
The bulb outage detection function for
trailer brake light cannot detect a
partial bulb outage. E.g. in case of
four bulbs with a power of 5 W each,
the function only detects lamp outage when only a single 5 W lamp remains
or none remain.
Fitting of towing equipment could
cover the opening of the towing eye. If this is the case use the coupling ball bar for towing. Always keep the
coupling ball bar in the vehicle when
not in use.Driving characteristics and
towing tips
Before attaching a trailer, lubricatethe 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
and caravan trailers with a permitted
gross vehicle weight of more than
1000 kg a speed of 80 km/h must not
be exceeded; the use of a stabiliser is
recommended.
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.
184Driving and operatingTrailer towingTrailer loadsThe permissible trailer loads are
vehicle 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 loads apply 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
3 238.
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.Petrol and diesel engines
The maximum permissible vertical
coupling load (55 kg) 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.Engine B14XEL LPG / D14XEL LPG
The maximum permissible vertical
coupling load (45 kg) 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.Rear axle loadPetrol and diesel engines
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) for passenger vehicles
may be exceeded by 70 kg for the 5-
door vehicle and 60 kg for the 3-door
vehicle, the gross vehicle weight
rating by 55 kg.Engine B14XEL LPG / D14XEL LPG
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) for passenger vehicles
may be exceeded by 70 kg for the 5-
door vehicle and 70 kg for the 3-door
vehicle and the gross vehicle weight
rating by 45 kg.Delivery van
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) for passenger vehicles
may be exceeded by 60 kg and the
gross vehicle weight rating by 55 kg.
Driving and operating185General
If the permitted rear axle load is
exceeded a maximum speed of
100 km/h applies. If lower national
maximum speeds are specified for
trailer operation, they must be
complied with.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Stowage of coupling ball bar
The coupling ball bar is stowed in a
bag in the spare wheel well and
secured to the lashing eyes in the
load compartment.
When inserting, fit protective cap over rotary knob with key.
Fitting the coupling ball bar
Disengage and fold down the socket. Remove the sealing plug from the
opening for the coupling ball bar and
stow it.
Checking the tensioning of the
coupling ball bar
● The rotary knob rests on the
coupling ball bar.
● Green marking on the rotary knob is not visible.
● Locking pin at the top of the coupling ball bar is set inwards.
● The key is in the lock.
