Additional to the side blind spot alert
3 203, lane change alert recognizes
rapidly approaching vehicles from
behind on parallel lanes next to your
vehicle.
If the vehicle is equipped with lane change alert, side blind spot alert is
always included.
The system alerts visually in each
exterior mirror when detecting rapidly
approaching vehicles from behind.
The radar distance sensors are
located in the rear bumper.9 Warning
Lane change alert does not
replace driver vision.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects an
approaching vehicle from behind
which drives considerably faster, the
amber warning symbol F will
illuminate in the relevant exterior
mirror. If the driver then activates the
turn signal, the warning symbol F
starts flashing amber as a warning not to change lanes.
When the vehicle is started, both
exterior mirror displays will briefly come on to indicate that the system is operating.

Note
After production, the system
requires a calibration. For optimal performance, drive as soon as
possible on a straight highway road
with roadside objects, e.g. guardrails
and barriers for some distance.
Fault
Occasional missed alerts can occur
under normal circumstances or in
sharp curves. The system can
temporarily alert of objects in the blind spot at specific weather conditions
(rain, hail etc). Driving on a wet road
or in the transitions from a dry area to a wet area can cause the system to
light up, as water splash can be
interpreted as an object. Otherwisethe system may light up due to
guardrails, signs, trees, shrubs or
other immobile objects. This is normal operation and the system does not
need to be serviced.

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.
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 sign is available, a + symbol is
displayed in this area.
222Driving and operatingFuel consumption data and CO2
emission data are determined
according to regulation R (EC) No.
715/2007 (in the version respectively
applicable), taking into consideration
the vehicle weight in running order, as specified by the regulation.
The figures are provided only for the
purpose of comparison between
different vehicle variants and must not be taken as a guarantee for the
actual fuel consumption of a
particular vehicle. Additional
equipment may result in slightly
higher results than the stated
consumption and CO 2 figures.
Furthermore, fuel consumption is
dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
The factory-fitted towing equipment is
folded up under the rear bumper
fascia.
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. Only use
towing equipment that has been
approved for your vehicle.
To avoid vehicle damage, the power
tailgate cannot be operated with the
radio remote control when a trailer is
electrically connected.
The bulb outage detection function for trailer brake light cannot detect a
partial bulb outage, e.g. in case of four
times five watt bulbs, the function only detects lamp outage when only a
single five Watt 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.Driving characteristics and
towing tips
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
and trailers with a permitted gross
vehicle weight of more than 1400 kg (Front-wheel drive)/1600 kg (All-
wheel drive) the use of a stabiliser is
strongly recommended when driving
above 80 km/h.
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 3 295.
Driving and operating223Trailer towingTrailer loads
The 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 12%.
The permissible trailer load applies
up to the specified incline and at 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 metres of 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
3 279.
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 (85 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 load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by 90 kg for the 5-door Hatchback/4-
door Saloon and 85 kg for the Sports
Tourer/Country Tourer, the gross
vehicle weight rating may be
exceeded by 65 kg for the 5-door
Hatchback/4-door Saloon and 60 kg for the Sports Tourer/Country Tourer. If the permissible rear axle load is
exceeded, a maximum speed of
100 km/h applies.
Towing equipmentCaution
The folding coupling ball bar
cannot be removed from the
vehicle. When driving without a
trailer, fold in the coupling ball bar.
Driving and operating225A buzzing tone sounds as a warning
when the release handle is pulled out
and the ball neck is disengaged.
With the flat of the hand, swivel the
released coupling ball bar to the right
until it engages under the floor. Make sure that the release handle is back inits hidden initial position, otherwise
the buzzing tone will not stop.
9 Warning
Towing a trailer is permitted only
when the coupling ball bar is fitted correctly. If the coupling ball bar
does not engage correctly or if the
release handle is impossible to guide to its hidden initial position in the housing or if the buzzing tone
sounds after engaging the
coupling ball bar, seek the
assistance of a workshop.
Eye for break-away stopping cable
Attach break-away stopping cable to
eye.
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 system is working keep steering wheel as still as possible.
Trailer stability assistant is a function
of the Electronic Stability Control
3 177.
