Introduction
This chapter contains information on the following subjects:
Electronic Stability Control (ESC)
119
Antilock Braking System (ABS)
120
Traction Control System (ASR)
120
Electronic Differential Lock (EDL)
120WARNING■ A lack of fuel can cause irregular engine running or cause the engine to
shut down. The brake assist systems would then fail to function – risk of
accident!■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions. The increased safety provided by the brake assist
systems must not tempt you to take safety risks – risk of accident!
■
In the event of an ABS fault, visit a specialist garage immediately. Adjust
your style of driving according to the damage to the ABS, as you will not
know the exact extent of the damage or the extent to which this is limiting the braking efficiency.
CAUTION
■ All four wheels must be fitted with the same tyres approved by the manufac-
turer to ensure the brake assist systems operate correctly.■
Changes to the vehicle (e.g. to the engine, brakes, chassis) can influence the
functionality of the brake assist systems » page 132, Services, modifications
and technical alterations .
■
If a fault occurs in the ABS system, the ESC, TCS and EDL will also fail to
work. An ABS fault is indicated with the warning light
» page 42 .
Electronic Stability Control (ESC)
Read and observe
and on page 119 first.
The ESC system helps to maintain control of the vehicle in situations where it
is being operated at its dynamic limits, such as a sudden change in the direc-
tion of travel. Depending on the road surface conditions, the risk of skidding is
reduced, thereby improving the vehicle's driving stability .
The ESC system is automatically activated each time the ignition is switched
on.
The direction which the driver wishes to take is determined based on the
steering angle and the speed of the vehicle and is constantly compared with
the actual behaviour of the vehicle. In the event of deviations occurring, such
as the car beginning to skid, the ESC system will automatically brake the ap-
propriate wheel.
During an intervention of the system, the warning light
flashes in the instru-
ment cluster.
The following systems are integrated into the electronic stabilisation control
(ESC) :
› Antilock brake system (ABS),
› Traction control (TCS),
› Electronic Differential Lock (EDL)
› Hydraulic Brake Assist (HBA)
› Hill Hold Control (HHC).
The ESC system cannot be deactivated. The
» Fig. 117 on page 120 button
can only be used to deactivate the TCS. The warning light comes on in the
instrument cluster when the TCS is deactivated.
In the event of an ESC fault, the ESC warning light illuminates in the instru-
ment cluster
» page 42 .
Hydraulic Brake Assist (HBA)
HBA increases the braking effect and helps to shorten the braking distance.
The HBA is activated by very quick operation of the brake pedal. In order to
achieve the shortest possible braking distance, the brake pedal must be ap-
plied firmly until the vehicle has come to a standstill.
The HBA function is automatically switched off when the brake pedal is re-
leased.
The ABS is activated faster and more effectively with the intervention of the
HBA.
Hill Hold Control (HHC)
When driving on slopes, HHC allows you to move your foot from the brake ped-
al to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brake
pedal for approx. 2 seconds after the brake pedal is released. 119Assist systems
Page 123 of 204
The brake pressure drops gradually the more you operate the accelerator ped-
al. If the vehicle does not start off within 2 seconds, it starts to roll back.
HHC is active on slopes of >5 % when the driver door is closed. HHC is always only active on slopes when in forward or reverse start off. When driving down-
hill, it is inactive.
Antilock Braking System (ABS)
Read and observe
and on page 119 first.
ABS prevents the wheels locking when braking. Thus helping the driver to
maintain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
When the ABS system is active, do not brake periodically or reduce the pres- sure on the brake pedal.
Traction Control System (ASR)
Fig. 117
TCS button
Read and observe and on page 119 first.
If the wheels are slipping, the ASR system adapts the engine speed to the con-
ditions of the road surface. The TCS makes it much easier to start off, acceler-
ate and climb steep hills even if the conditions of the road surface are unfav-
ourable.
The TCS function is automatically activated each time the ignition is switched
on.
During an intervention of the system, the TCS warning light flashes in the
instrument cluster.
The TCS should normally always be enabled. Only in certain exceptional cir-
cumstances can it be sensible to switch the system off, for instance:
› when driving with snow chains;
› when driving in deep snow or on a very loose surface;
› when it is necessary to “rock a vehicle free” when it has got stuck.
Ensure the TCS is activated again afterwards.
You can switch TCS off and on again as needed by pressing the
but-
ton » Fig. 117 . The
warning light comes on in the instrument cluster when the
TCS is deactivated.
The TCS warning light
» page 45 lights up in the instrument cluster when
there is a fault on the TCS.
Electronic Differential Lock (EDL)
Read and observe
and on page 119 first.
If one of the wheels starts to spin, the EDL system brakes the spinning wheel
and transfers the driving force to the other wheels. This ensures the stability
of the vehicle and a quick journey.
EDL switches off automatically to avoid excessive heat generation on the
brake of the wheel being braked. The vehicle can continue to be driven and
has the same characteristics as a vehicle not fitted with EDL. The EDL switches
on again automatically as soon as the brake has cooled down.

Switching off temporarily123Switching off completely123
The Cruise Control System (CCS) maintains a set speed, more than 25 km/h,
without you having to actuate the accelerator pedal.
This is only possible within the range which is permitted by the power output and braking power of the engine.
The
warning light in the instrument cluster lights up when the cruise con-
trol system is switched on.
WARNING■ For safety reasons, the cruise control system must not be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads,
loose gravel) – there is a risk of an accident.■
The saved speed may only be resumed if it is not too high for the current
traffic conditions.
■
Always deactivate the cruise control system after use to prevent the sys-
tem being switched on unintentionally.
CAUTION
■ The cruise control system is not able to maintain a constant speed when
driving in areas with steeper gradients. The weight of the vehicle increases the
speed at which it travels. Therefore, shift to a lower gear in good time or slow
the vehicle down by applying the foot brake.■
It is not possible to switch on the cruise control system on vehicles fitted
with a manual gearbox if the first gear or reverse gear is engaged.
■
On vehicles fitted with an automatic gearbox, it is not possible to switch on
the cruise control system if the selector lever is in position P, N or R.
■
The Cruise Control System may automatically switch off when some brake
assist systems (e.g. ESC) intervene, when the speed exceeds maximum permis-
sible engine speed, or a similar event takes place.

Information messages
124The START-STOP system (hereinafter referred to as the system) saves fuel and
reduces polluting emissions and CO 2 emissions by turning the engine off, e.g.
when stopping at traffic lights, and starting the engine again when moving off.WARNING■ Never let the vehicle roll with the engine switched off.■The brake servo unit and power steering only operate if the engine is run-
ning.
Operating conditions for the system
Fig. 120
Maxi DOT display: Engine is auto-
matically switched off / automat-
ic engine cut off is not possible
Read and observe on page 123 first.
For system-dependent automatic engine shutdown to work, the following
conditions must be met.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed exceeded 4 km/h after the last stop.
No trailer is coupled.
Some additional conditions for the system to function correctly cannot be in-
fluenced or recognised by the driver. Therefore, the system can react differ-
ently in situations which are identical from the driver's perspective.
If after stopping the car, the message START-STOP NOT POSSIBLE appears in
the segment display or the MAXI DOT display shows the
» Fig. 120 warning
sign, then the conditions for automatic engine shutdown are not being met.
123Assist systems
Page 127 of 204
Running the engine is essential for the following reasons, for example.
› The engine temperature for the proper function of the system has not yet
been reached.
› The charge state of the vehicle battery is too low.
› The current consumption is too high.
› High air-conditioning or heating capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
Note
■ If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
manually.
■
After the manual engine start, the automatic engine shutdown can take
place only when a minimum distance required for the system function has
been covered.
Operation

System related automatic start-up
Read and observe
on page 123 first.
When the engine is off, the system can automatically start the engine beforethe desired journey continues. Some possible reasons for this are:
› The vehicle has begun to roll, e.g. on a slope.
› The brake pedal has been actuated several times.
› The current consumption is too high.

.
Ensure that the breakaway cable of the trailer, when it is mounted into the
safety eye on all trailer positions relative to the vehicle (sharp curves, reverse
driving and the like), is seen to sag.
The uncoupling of the trailer is carried out in reverse order.
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see
the traffic behind the trailer with the standard rear-view mirrors. The national
legal requirements must be observed.
Headlights
The front of the vehicle can be lifted when a trailer is being towed and the
headlights can dazzle other road users.
Adjust the headlight setting on the headlight range control » page 60, Head-
light beam adjustment .
WARNING■
Incorrectly or improperly connected electrical installations may cause mal-
function of the entire vehicle electronics and lead to accidents and serious
injury from electric shock.■
Work on the electrical system must only be carried out by specialist ga-
rages.
■
Never directly connect the trailer's electrical system with the electrical
connections for the tail lights or other current sources.
■
After coupling the trailer and connecting up the power socket, check the
rear lights on the trailer to ensure they are working.
■
The handbrake on the towing vehicle must be applied when coupling and
uncoupling the trailer.
■
Never use the safety eyelet for towing!
Loading a trailer
The vehicle/trailer combination must be balanced, whereby the maximum per-
missible drawbar load must be utilised. If the drawbar load is too low, it jeop-
ardises the performance of the vehicle/trailer combination.
Distribution of the load
Distribute the load in the trailer in such a way that heavy items are located as
close to the axle as possible. Secure the items from slipping.
The distribution of the weight is very poor if your vehicle is unladen and the
trailer is laden. Maintain a particularly low speed if you cannot avoid driving
with this combination.
Tyre pressure
Correct the tyre inflation pressure on your vehicle for a “full load” » page 157.
Trailer load
The permissible trailer load must not be exceeded under any circumstan-
ces » page 183 , Technical data .
The details given in the vehicle's technical documentation always take prece-
dence over the details in the Owner's Manual.
The trailer loads specified apply only to altitudes up to 1,000 metres above
mean sea level.
The engine output falls as altitude increases, as does the ability to climb.
Therefore, for every additional 1000 m in height (or part), the maximum per-
missible towed weight must be reduced by 10 %.
130Driving
Page 134 of 204
The towed weight comprises the actual weights of the (loaded) towing vehicle
and the (loaded) trailer.
The trailer and drawbar load information on the type plate of the towing
equipment are merely test data for the towing equipment. The vehicle-specific
values are detailed in the vehicle documents.WARNING■ The maximum permissible axle and drawbar load and the permissible
weight of the trailer must not exceed - this could cause an accident!■
A sliding cargo can significantly adversely affect stability and driving safe-
ty - there is a risk of accident!
Towing a trailer
Driving speed
For safety reasons, do not drive faster than 80 km/h when towing a trailer.
Immediately reduce your speed as soon as even the slightest swaying of the
trailer is detected. Never attempt to stop the trailer from “swaying” by acceler-
ating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply
the brakes gently at first, then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as
a brake.
Engine overheating
The speed must be reduced immediately if the needle for the coolant tempera-
ture gauge moves into the right-hand area or the red area of the scale.
Stop and switch off the engine if the warning light in the instrument cluster
starts to flash. Wait a few minutes and check the level of coolant » page 151,
Checking the coolant level .
Further information » page 41,
Coolant
.
The coolant temperature can be reduced by switching on the heating.
WARNING■ Always drive particularly carefully with the trailer.■Adapt your speed to the conditions of the road surface and to the traffic
situation.
Note
If you tow a trailer frequently, you should also have your vehicle inspected be-
tween service intervals.
Anti-theft alarm system
When the vehicle is locked, the alarm is activated when the electrical connec-
tion to the trailer is interrupted.
Always switch off the anti-theft alarm system before a trailer is coupled or un-
coupled » page 53 .
Conditions for including a trailer in the anti-theft alarm system. The vehicle is factory-fitted with an anti-theft alarm system and towing
equipment.
The trailer is electrically connected to the towing vehicle by means of the
trailer socket.
The electrical system of the vehicle and trailer is functional.
The vehicle is locked with the vehicle key and the anti-theft alarm system
is activated.
CAUTION
For technical reasons, trailers with rear LED lights cannot be connected to the
anti-theft alarm system.131Hitch and trailer

Trailer fitting and mounting recessRead and observe
and on page 136 first.
Close the mounting recess with the cap to prevent any ingress of dirt.
If dirt is present, clean the inner surfaces of the mounting recess and treat
with a suitable preservative.
Always check the ball head before hitching a trailer. Apply a suitable grease, if
necessary.
Fit the protective cap when stowing away the ball head to protect the luggage
compartment against dirt.
CAUTION
Apply grease to the inner part of the mounting recess. Make sure you do not
remove any grease.
Wheels
Read and observe
and on page 136 first.
Wheel rims
Also thoroughly wash the wheel rims when washing the vehicle on a regular
basis.
Regularly remove salt and brake abrasion, otherwise the rim material will be
corroded.
Damage to the paint layer on the wheel rims must be touched up immediately.
Light alloy wheels
After washing thoroughly and treat the wheel rims with a protective product
for light alloy wheels. Products which cause abrasion must not be used to
treat the wheel rims.
CAUTION
Severe layers of dirt on the wheels can also result in wheel imbalance. This
may show itself in the form of a wheel vibration which is transmitted to the
steering wheel which, in certain circumstances, can cause premature wear of
the steering. This means it is necessary to remove the dirt.Underbody protection
Read and observe
and on page 136 first.
The underside of your vehicle is protected for life against chemical and me-
chanical influences.
When driving, it cannot be guaranteed that no damage to the protective layer
will occur.
We recommend having the protective layer underneath the vehicle and the
chassis checked — preferably before the beginning of winter and at the end of
winter.
WARNINGNever use additional underbody protection or anti-corrosion agents for ex-
haust pipes, catalytic converters, diesel particle filters or heat shields.
When the engine reaches its operating temperature, these substances may ignite - risk of fire!

WARNINGThe national legal requirements must be observed if carrying a spare canis-
ter in the vehicle. We do not recommend carrying any fuel canisters in your
vehicle for safety reasons. in the event of an accident, these canisters can
become damaged and fuel may escape – risk of fire!
CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of
fuel can cause misfiring, which can result in damage to parts of the engine and
the exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork –
risk of paint damage!
■
If the vehicle was not purchased in the country in which it was intended to
be operated, you should check whether the fuel specified by the manufacturer
is offered in the country where the vehicle will be operated. You should also
perhaps check whether the manufacturer has recommended a different fuel
for operation of the vehicle in the country concerned. If no prescribed fuel is
available, then you must check whether it is permitted by the manufacturer to
operate the vehicle with another fuel type.

CAUTION
■ Before refuelling it is necessary to switch off the auxiliary heating system
(auxiliary heating and ventilation).■
The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Do not continue filling
the fuel tank otherwise the expansion volume is filled up.
Note
The fuel tank has a capacity of about 55 litres, including a reserve of approx.
7 litres .Unleaded petrol
Read and observe
and on page 142 first.
The vehicle can only be operated with unleaded petrol that meets the EN 2281)
standard.
All petrol engines can be operated using petrol with a maximum of 10% bioe-
thanol (E10).
Specified fuel - unleaded petrol 95/91 or 92 or 93 RON
Use unleaded fuel with an octane rating of 95 RON. Unleaded petrol with the
octane ratings 91 or 92 or 93 RON can also be used, but may result in a slight
loss in performance and slightly increased fuel consumption .
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded fuel with an octane rating of 95 RON or higher.
If unleaded gasoline is not available with the octane number 95 RON, in an
emergency petrol with the octane rating of 91 or 92 or 93 RON can be used to
fill the tank, but this leads to a slight loss of performance and a slightly in-
creased fuel consumption »
.
Prescribed fuel - unleaded petrol 98/(95) RON
Use unleaded fuel with an octane rating of 98 RON or higher. Unleaded petrol
95 RON can also be used but results in a slight loss in performance.
In an emergency, if unleaded petrol with an octane rating of 98 RON or 95 RON
is not available, you may refuel with petrol with an octane rating of 91 or 92 or
93 RON »
.
Fuel additives
Unleaded petrol complying with EN 228 1 )
meets all the conditions for a
smooth-running engine. We therefore recommend that no fuel additives are
used. This can result in considerable damage to parts of the engine or the ex-
haust system.
1)
In Germany also DIN 51626-1 or E10 for unleaded petrol with octane rating 95 or 91 or DIN 51626-2 or E5
