Dash panel: switch for hazard warn-
ing lights. Read the additional information carefully
›››  page 15
The hazard warning lights are used to draw
the attention of other road users to your vehi-
cle in emergencies.
If your vehicle breaks down:
1. Park your vehicle at a safe distance from moving traffic.
2. Press the button to switch on the hazard warning lights ››› .
3. Switch the ignition off.
4. Apply the handbrake.
5. For a manual gearbox, engage 1st gear; for an automatic gearbox, move the gear
lever to P
. 6. Use the warning triangle to draw the atten-
tion of other road users to your vehicle.
7. Always take the vehicle key with you when you leave the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps  
and the t

urn signal lamp in the switch  will
flash at the same time. The hazard warning
lights also work when the ignition is switch-
ed off.
Emergency braking warning
If the vehicle is braked suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times
per second to warn vehicles driving behind. If
you continue braking, the hazard warning
lights will come on automatically when the
vehicle comes to a standstill. They switch off
automatically when the vehicle starts to
move again. WARNING
● The risk of an accident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Never park where the catalytic converter
could come into contact with inflammable materials under the vehicle, for example dry
grass or spilt petrol. This could start a fire!
Note
● The battery will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
scribed here is subject to the relevant statu-
tory requirements. Parking light
When the parking light is switched on, (right
or left turn signal), the front side light and
the rear light on the corresponding side of
the vehicle stay lit. The parking lights can on-
ly be activated with the ignition switched off
and the turn signal and main beam lever in
the central position, before being triggered.
Parking light on both sides With the ignition switched off and the light
switch in position 
, when locking the vehi-
cle from the outside, the parking lights on
both sides of the vehicle light up. In doing
so, only the side lights of both headlights
light up, and additionally the tail lights will
do so partially.

Operation
Note
The system is automatically switched on each
time the engine is deliberately stopped dur-
ing a stopping phase. The engine will start
automatically. Driver messages on the instrument
panel display
Start-Stop system deactivated. Start the
engine manually
This driver message is displayed when cer-
tain conditions are not met during the stop-
ping phase and the Start-Stop system cannot
restart the engine. The engine must be star-
ted manually.
Start-Stop system: Fault! Function not available
There is a fault in the Start-Stop system. Take
the vehicle to a workshop to have the fault
repaired.
Cruise control system (CCS)* How it works The cruise control system (CCS) is able to
maintain the set speed from 20 km/h (15
mph). The CSS only reduces vehicle speed by ceas-
ing to accelerate, not by actively braking the
vehicle
››› .
WARNING
Use of the cruise control could cause acci-
dents and severe injuries if it is not possible
to drive at a constant speed maintaining the
safety distance.
● Do not use the cruise control in heavy traf-
fic, if the distance from the vehicle in front is
insufficient, on steep roads, with several
bends or in slippery circumstances (snow,
ice, rain or loose gravel), or on flooded roads.
● Never use the CCS when driving off-road or
on unpaved roads.
● Always adapt your speed and the distance
to the vehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● To avoid unexpected operation of the cruise
control system, turn it off every time you fin-
ish using it.
● It is dangerous to use a set speed which is
too high for the prevailing road, traffic or
weather conditions.
● When travelling down hills, the CCS cannot
maintain a constant speed. The vehicle tends
to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the
vehicle. Warning and control lamp

Operation
Deceleration until the vehicle has stopped
(only vehicles with automatic gearbox)
If the vehicle in front slows down and stops,
the ACC will also slow down and halt the ve-
hicle. After approximately 3 seconds the sys-
tem will inform the driver that he or she
should take control of the vehicle by means
of an audible and visual warning on the in-
strument panel.
Starting driving after a stopping phase (only
vehicles with automatic gearbox)
After a stopping phase the ACC may begin
driving automatically when the vehicle in
front drives off.
Overtaking
When the turn signal lights up before the ve-
hicle begins an overtaking manoeuvre, the
ACC accelerates the vehicle automatically
and thus reduces the distance from the vehi-
cle in front.
When the vehicle enters the overtaking lane,
if the ACC does not detect another vehicle in
front, it accelerates until it reaches the pro-
grammed speed and maintains it.
System acceleration can be interrupted at
any time by pressing the brake or moving the
third lever backwards ›››
page 154. Driving through a bend
On entering or exiting bends, the radar sen-
sor may no longer determine the vehicle in
front or react to a vehicle in the adjacent lane
››› Fig. 156
A. In these situations the vehicle
may brake unnecessarily or fail to react to re-
act to the vehicle in front. In this case, the
driver has to intervene by accelerating or in-
terrupting the braking process by applying
the brake or pushing the third lever back-
wards ››› page 154.
Drivin

g in tunnels
When driving through tunnels the radar sen-
sor may be limited. Switch off the ACC in tun-
nels.
Narrow or misaligned vehicles
The radar sensor can only detect narrow or
misaligned vehicles when they are within
range ››› Fig. 156
B. This applies particularly
to narrow vehicles such as motorbikes. In
these cases, you should brake as necessary.
Vehicles with special loads and accessories
Special loads and accessories of other vehi-
cles that jut out over the sides, backwards or
over the top may be out of the ACC's range.
Switch off the ACC when driving behind vehi-
cles with special loads and accessories or
when overtaking them. In these cases, you
should brake as necessary. Other vehicles changing lanes
Vehicles changing lanes a short distance
away from your own can only be detected
when they are within range of the sensors.
Consequently, the ACC will take longer to re-
act
››› Fig. 157 C
. In these cases, you should
brake as necessary.
Stationary vehicles
The ACC does not detect stationary objects
while driving, such as traffic tails or damaged
vehicles.
If a vehicle detected by the ACC turns or
moves over and there is a stationary vehicle
in front of it, the ACC will not react to it
››› Fig. 157 D
. In these cases, you should
brake as necessary.
Vehicles driving in the opposite direction
and vehicles crossing your path
The ACC does not react to vehicles approach-
ing from the opposite direction or vehicles
crossing your path.
Metal objects
Metal objects, e.g. rails on the road or sheets
used in road works, can confuse the radar
sensor and cause the ACC to react wrongly.

Operation
Operating mode Fig. 164
In the windscreen: field of vision of
the Lane Assist system camera. Using the camera located in the windscreen,
the Lane Assist system detects the possible
lines dividing the lanes. When the vehicle in-
voluntarily approaches a dividing line it has
detected, the system notifies the driver with
a
corrective steering movement
.
Thi s move-
ment can be over-regulated at any time.
No warning is produced with the turn signals
activated, given that the Lane Assist system
understands that a lane change is required.
Steering wheel vibration
The following situations cause vibration in
the steering wheel and require the driver to
take active control of driving:
● When the limits of the very nature of the
system are reached. ●
When the maximum rotational torque dur-
ing the corrective steering movement is not
enough to keep the vehicle inside the lane.
● When no lane is detected during the correc-
tive steering movement.
Switching the Lane Assist system on or off
Through the Easy Connect system
● Push the Easy Connect button CAR ●
Push the Setup function button
● Press the function button driver assistance to

Operation
to be reduced accordingly. The weight of the
vehicle and trailer combination must be re-
duced by 10% for every further 1000 m (or
part thereof). The gross combination weight
is the actual weight of the laden vehicle plus
the actual weight of the laden trailer. When
possible, operate the trailer with the maxi-
mum permitted drawbar load on the ball joint
of the t
owing bracket, but do not exceed the
specified limit.
The figures for trailer weights
and drawbar
loads that are given on the data plate of the
to
wing bracket are for certification purposes
only. The correct figures for your specific
model, which may be lower than these fig-
ures for the towing bracket, are given in the
vehicle documentation or in ››› chapter Tech-
nical Data .
Distributing the load
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Loads carried in the trailer must be secured
to prevent them moving.
Tyre pressure
Set tyre pressure to the maximum permissi-
ble pressure shown on the sticker on the in-
side of the fuel tank flap. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations. Exterior mirrors
Check whether you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear.
Tow rope
Always use a cable between the vehicle and
the trailer
››› page 178.
Tr
ailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 178. WARNING
Never transport people in a trailer. This could
result in fatal accidents. Note
● Towing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to towing a trailer in your country. Hitching and connecting the trailer

13Earth, pin 9 Electrical socket for trailer
The vehicle is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the system de-
tects that a trailer has been connected elec-
trically, the electrical equipment on the trailer
will receive voltage through this connection.
Pin 9 has a permanent live. This powers, for
example, the trailer's interior lighting. Pin 10
is only powered when the engine is running.
The charge wire (pin 10) charges, for exam-
ple, a caravan battery.
Pin 9 and 10 should not be connected to
each other to avoid discharging or damaging
the vehicle's battery.
The earth wires, pin 3, pin 11 and pin 13,
should never be connected to each other to
avoid overloading the electrical system.
If the trailer has a
7-contact connector , you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available. Trailer maximum electricity consumption

Never exceed the values indicated!
Note
● If the rear lights of the trailer are not cor-
rectly connected, the vehicle electronics may
be damaged.
● If the trailer absorbs excessive electric cur-
rent, the vehicle electronics may be dam-
aged.
● Never connect the trailer's electric system
directly to the electrical connections of the
tail lights or any other power sources. Only
use the connections intended for providing
electric current to the trailer. Ball coupling of towing bracket*
The ball coupling is provided with instruc-
tions on fitting and removing the ball cou-
pling of the towing bracket. WARNING
The towing bracket ball coupling must be
stored securely in the luggage compartment
to prevent them being flung through the vehi-
cle and causing injury. Note
● By law, the ball coupling must be removed
if a trailer is not being towed if it obscures
the number plate. Driving tips
Driving with a trailer always requires extra
care.
Weight distribution
The weight distribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum
permissible speed in an unfavourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.

Emergencies
Do not pull too hard with the towing vehicle
and take care to avoid jerking the tow rope.
When towing on an unpaved road, there is al-
ways a risk of overloading and damaging the
anchorage points. WARNING
If the vehicle has no electrical power, the
brake lights, turn signals and all other lights
will no longer function. Do not have the vehi-
cle towed away. Failure to follow this instruc-
tion could result in an accident. CAUTION
If there is no oil in the gearbox or no lubricant
in the automatic transmission the car may
only be towed with the driven wheels lifted
clear of the road, or transported on a special
car transporter or trailer. Note
● Please observe related legal requirements.
● Switch on the hazard warning lights of both
vehicles. However, observe any regulations
to the contrary.
● The tow rope must not be twisted. Other-
wise the front towline anchorage could be
pulled off the vehicle. Towline anchorage at the front of the

● Take particular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The
glass can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure yourself on sharp edges, in particu-
lar on the headlight housing. CAUTION
● Remove the ignition key before working on
the electric system. Otherwise, a short circuit
could occur. ●
Switch off the lights and the parking light
before changing a bulb.
● Take good care to avoid damaging any com-
ponents. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of used bulbs in the proper manner. Note
● Please check at regular intervals that all
lighting (especially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users.
● Before changing a bulb, make sure you
have the correct new bulb.
● Do not touch the glass part of the bulb with
your bare hands, use a cloth or paper towel
instead, since the fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, they will be deposited on
the reflector and will impair its surface. 234
