NoteIf the ABS warning lamp lights up, this can also mean there is a fault in the
EDL. Please take the vehicle to a qualified workshop as soon as possible.Traction control system (TCS)
The traction control system prevents the drive wheels from
spinning when the vehicle is accelerating.General notes
The traction control system (TCS) is one of the functions incorporated in the
Electronic Stability Programme (ESP).
The traction control system (TCS) helps the vehicle to start moving, accelerate
or climb a gradient in slippery conditions where this may otherwise be diffi-
cult or even impossible.
How it works
The TCS acts automatically, without the driver’s intervention. With the aid of
the ABS sensors ⇒page 186, the TCS monitors the speed of the drive
wheels. If the wheels start to spin, the engine speed is reduced automatically
to match the amount of grip available. The system is active across the entire
speed range.
The TCS works in conjunction with the ABS. If a malfunction occurs in the ABS,
the TCS will also be inoperative.
Note
To ensure that the TCS works properly, all four wheels must be fitted with
identical tyres. The difference in size of the wheels may lead to an undesired
reduction in engine power. Also see ⇒page 244.

Driving and the environment195

Practical Tips

Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a very long time to warm up when it is running at idling
speed. Mechanical wear and pollutant emissions are also especially high
during this initial warm-up phase. It is therefore best to drive off immediately
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum
service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible. Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressure is just 1 bar too low, fuel consumption can increase by as much
as 5%. Due to the greater rolling resistance, under-inflation also increases
tyre wear
and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120km/h your vehicle will use about
12% m ore fuel as a result of the extra wind resistance caused by the roof rack
even when it is not in use.
Save electricity
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical components when you do not need them. Examples of
components that use a lot of electricity are: the fan at high speeds, the rear
window heating or the seat heaters*.
Note
•If you vehicle has Start-Stop, it is not recommended to disconnect this
function.•It is recommended to close the windows when driving at more than 60
km/h

Adhesive strips for headlightsIf you have to drive a right-hand drive vehicle in a left-hand drive country, or
vice versa, the asymmetric dipped beam headlights will dazzle oncoming
traffic.
To prevent dazzling, you must apply stickers to certain parts of the headlight
lenses. Further information is available at your Authorised Service Centre.
In vehicles with adaptive headlights, the rotation system must previously be
disconnected. To do this, please go to a specialised workshop.

Trailer towing199
Safety First
Operating Instructions
Practical Tips
Technical Specifications
Where possible, operate the trailer with the maximum permitted
drawbar
load on the ball joint of the towing bracket, but do not exceed the specified
limit.
Tyre pressure
Check the tyre pressures on your vehicle, and adjust for “full load” conditions
(refer to the sticker listing the tyre pressures on the door pillar). It may also be
necessary to adjust the tyre pressures on the trailer according to the recom-
mendations of the trailer manufacturer.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. The two exterior mirrors should be fitted on folding arms. Adjust the
mirrors to give sufficient rear vision.
Headlights
Before starting a journey, check the headlight beam settings with the trailer
hitched up. If necessary, alter the height of the headlight beams by means of
the headlight range control. See ⇒page 119.
Power supply
When you remove the ignition key, the power supply to the trailer is inter-
rupted.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are equipped with a removable
ball joint coupling. This is stored in the spare wheel well in the luggage
compartment together with the necessary fitting instructions.
Note
If you frequently tow, we recommend you also have the vehicle serviced
between services.
Notes on towing
Towing a trailer involves additional attention by the driver.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slow to allow for
the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. There-
fore, it is advisable not to drive at the maximum permissible speed in unfa-
vourable road, weather or wind condit ions. This especially applies when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of swaying . Never try to stabilise the trailer by accelerating.
Anticipate hazards and brake in good time. If towing a trailer with an inertia
brake , first brake gently and then harder. This will prevent brake tapping by
the trailer wheels when they lock. Select a low gear in due course before
going down a steep downhill. This enables you to use the engine braking to
slow down the vehicle.
Swaying and pitching can be reduced by stabiliser aids. We recommend
having stabiliser aids installed when towing trailers with a high trailer weight.
They can be purchased and installed at a Technical Service.
Reheating
When climbing long hills in hot weather with the engine running fast in low
gear, you should keep an eye on the coolant temperature gauge ⇒page 60.
Reduce speed immediately if the needle moves to the right end of the scale.
If the temperature warning lamp
v in the instrument panel should start
flashing, stop the vehicle and let the engine cool down by running it at idling
speed for a few minutes.

The tyre pressure warning lamp
~ lights up if the tyre pressure on one or
more wheels is significantly lower than the tyre pressure setting which was
confirmed by the driver ⇒.
WARNING
•If the tyre pressure warning lamp lights up
~ you must slow down
immediately and avoid any severe braking or steering manoeuvres. Stop
the vehicle as soon as possible and check the tyres and their pressure.
•The driver is responsible for maintaining correct tyre pressures. There-
fore, the tyre pressure must be regularly checked.•Under certain conditions (e.g. driving at high speeds, on ice and snow
or on poor road surfaces) the tyre pressure warning lamp
~ may not light
up immediately or not at all.
•Please ask your Dealer or qualified workshop whether run-flat tyres can
be used on your vehicle. Fitting this type of tyre in an undue manner could
lead to your driving licence being taken away from you. Furthermore, it may
led to damage to the vehicle or, under certain circumstances, may cause
accidents.•If you change normal tyres for run-flat tyres or vice versa, the control
unit must be reprogrammed by the Dealer or a qualified workshop.Note
If you did not press the button for the tyre pressure monitoring system to
confirm a new tyre pressure setting after making changes to the tyre pres-
sures or changing one or more wheels, the warning lamp
~ may light up
although the tyre pressures are correct. In this case, stop the vehicle as soon
as possible and, after examining the tyres, press the button for the tyre pres-
sure monitoring system.
Tyre ser vice life
The service life of tyres is dependent on tyre pressure, driving
style and fitting.

Your vehicle can be factory-equipped with a spare steel wheel. The spare
wheel does
not usually meet the same performance standards as the wheels
fitted on the vehicle because of the wheel/tyre dimensions, rubber composi-
tion, tread pattern, etc. Therefore, note the following restrictions:
•The spare steel wheel is designed only for your vehicle model. Do not
attempt to mount the wheel on any vehicle but your own.•Your vehicle will have different driving characteristics when the spare
steel rim wheel is mounted ⇒.•The spare wheel is only intended for temporary use after having a flat tyre.
Replace the spare wheel with a normal wheel that has the proper tyre dimen-
sions as soon as possible.•If the size of the spare steel rim wheel is different to that of the other
wheels, it is unlikely that snow chains suitable for the other wheels will fit it.WARNING
•After mounting the spare steel rim wheel, the tyre pressure must be
checked and corrected as soon as possible. The tyre pressure must corre-
spond to the vehicle load (consult th e table containing the inflation pres-
sures). Otherwise there is danger of causing an accident. Use the highest
tyre pressure as indicated in the table.•Do not drive faster than 80 km/h, as higher speeds can cause an acci-
dent.•Avoid heavy acceleration, hard braking and fast cornering, as this could
cause an accident.
Changing a wheelPreparation work
What you must do before changing a wheel.– If you have a flat tyre or puncture, park the vehicle as far away from the flow of traffic as possible. Choose a location that is as
level as possible.
–All passengers should leave the vehicle. They should wait in a
safe place (e.g. behind the roadside crash barrier).
–Apply the handbrake firmly.
– Engage 1st gear .
– When towing a trailer: Unhitch the trailer from your vehicle.
– Take the tools and the spare wheel ⇒ page 247 out of the
luggage compartment.
WARNING
If you have a puncture in heavy traffic, switch on the hazard warning lights
and place the warning triangle in a visible location. This is for your own
safety and also warns other road users.
Caution
If you have to change the tyre on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.

– If the tyre pressure remains lower than the value specified above
drive the vehicle approx. 10 metres forwards or backwards, so
that the sealant can spread evenly in the tyre. If the pressure is
still lower than the specification the tyre is too badly damaged
and cannot be repaired using the tyre sealant.
Final check
– After about 10 minutes, stop to check the tyre pressure.
– If tyre pressure is less than 1.3 bar, the tyre is too badly damaged. Do not drive on! You should obtain professional
assistance.
WARNING
•If you have a puncture in heavy traffic, switch on the hazard warning
lights and place the warning triangle in a visible location. This is for your
own safety and also warns other road users.•Make sure your pass engers wait in a safe place ( for instance behind t he
roadside crash barrier).•Please observe the manufacturer’s safety notes on the compressor and
the instructions supplied with the tyre sealant can.•If it is not possible to build up a tyre pressure of 2.0 bar within 6
minutes this means that the tyre is too badly damaged. Do not drive on!•Seek professional assistance if the repair of a tyre puncture is not
possible with the sealing compound.•If tyre pressure is less than 1.3 bar after driving about 10 minutes, the
tyre is too badly damaged. Do not drive on! Obtain technical assistance.Caution
Take special care if you have to repair a tyre on a slope.
Note
•Do not use the compressor for longer than 6 minutes. Otherwise, it might
overheat. When the compressor has cooled down, you can use it again.•If tyre sealant should leak out, leave it to dry and then pull it off like foil.•After carrying out a tyre repair remember to buy a new tyre sealant can at
a qualified workshop. This will ensure that the Tyre Mobility System is opera-
tive again.•Please observe legal requirements when doing so.

Note
•Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This has
no influence on the useful life of the lighting system. By switching on the
lights, the area through which the beam of light is projected will quickly be
demisted. However, the edges may continue to be misted.•Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning pr operly. This is not only in the interest
of your own safety, but also in 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. Otherwise, the fingerprints left on the glass will vaporise as a result of the heat generated by the bulb, be deposited on the
reflector and impair its surface.
