Driving
instance when you can see that the next traffic
lights are red. This takes advantage of the engine
braking effect, reducing wear on the brakes and

tyres.
Emissions and fuel consumption will drop
to zero due to the overrun fuel cut-off.
Change gear early to save fuel
An effective way of saving fuel is to change up
quickly through the gears. Running the engine at
high rpm in the lower gears uses an unnecessary
amount of
fuel.

Applies to: vehicles with manual gearbox
Shift up to second gear as soon as possible. If
possible, we recommend shifting up to the next
gear at approx. 2,000 rpm.
Applies to: vehicles with automatic gearbox
Press the accelerator slowly and avoid using the

"kick-down"
feature.
Avoid driving at high speed
Avoid travelling at top speed. Fuel consumption,
exhaust emissions and noise Levels all increase
very rapidly at higher speeds. Driving at moder­
ate speeds will help to save
fuel.

Do not let the engine idle for longer than
necessary
Engine idling periods are automatically reduced
on vehicles with start/stop system*. On vehicles
without a start/stop system, it is worthwhile
switching off the engine at level crossings, for in­
stance, or at traffic lights with a long red phase.
The fuel saved after about 5 seconds can be
greater than the amount of fuel needed to re­
start a warm engine (the exact fuel saving de­
pends on the engine version).
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.

o
Regular servicing
Regular servicing can establish a basis for good

iS
fuel economy before you start driving. A
well-

serviced engine gives you the benefit of im­
proved fuel efficiency as well as maximum relia­
bility and an enhanced resale value. A poorly
maintained engine can consume up to ten per­
cent more fuel than necessary.
Avoid short trips
The engine and emission control system need to
reach their proper working temperature in order
to minimise fuel consumption and emissions.
A cold engine uses disproportionately more
fuel.

The engine only reaches its working temperature
after about four kilometres, when fuel consump­
tion will return to a normal level.
Check tyre pressures
Always make sure the tyres are inflated to the
correct pressures
•=>page
306 to save
fuel.
If the
tyre pressures
are
just 0.5
bar
too Low, this can
increase the fuel consumption by as much as 5
%. Due to the greater rolling resistance, under-
inflation also increases tyre wear and impairs

handling.

Do not use winter tyres all through the year; they
will increase fuel consumption by up to 10 %.
Avoid carrying unnecessary loads
Every kilo of extra weight will increase the fuel
consumption, so it is worth checking the Luggage
compartment occasionally to make sure that no
unnecessary loads are being transported.
The roof carrier increases the air resistance of the
vehicle and should be removed when not in use.
This will save about 12 % of fuel at speeds of be­
tween 60 and 75
mph.

Save electrical energy
The engine drives the alternator to generate elec­
tricity. This means that fuel consumption rises
when more power is required for electrical equip­
ment. Switch off electrical equipment when it is
not needed. Electrical equipment which uses a
lot of electricity includes the blower (at a high
setting), the rear window heating and the seat

heating*.

Towing a trailer
Tyre pressure
Check the tyre pressures on your car, and adjust
for "full
load"
conditions (refer to the sticker list­
ing the tyre pressures)
^>page
307. It may also
be necessary to adjust the tyre pressures on the
trailer according to the recommendations 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. Both exterior mirrors should be
mounted on hinged extension brackets. Adjust
the mirrors to give sufficient vision to the rear.
Headlights
Before starting
a
journey, check the headlight
beam settings with the trailer hitched up. Adjust
the headlight settings if necessary.
On vehicles with halogen headlights, the
head­

light range control must be adjusted, see

tapage
49.
The headlight range control will be adjusted au­
tomatically if your vehicle is equipped with LED
headlights*.
Power supply
To ensure that the engine can be started again
after the ignition is switched off, the power
man­

agement system
^>page
149 controls the distri­
bution of electrical power and gradually switches
off unnecessary electrical equipment. The trailer
is supplied with power during this period. The
power supply to the trailer is interrupted while
the engine is being started.
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 or in a sepa­
rate bag on the floor of the luggage compart­
ment, together with the necessary fitting instruc­

tions.

We recommend having the car serviced be­
tween the normal inspection intervals if it
used frequently for towing a trailer.
Trailer stabilisation system
Applies to: vehicles with towing bracket
Trailer stabilisation helps to reduce the risk of
the vehicle skidding when towing a
trailer.

When is the trailer stabilisation
system1'

activated?
Trailer stabilisation is active when the following
requirements are met:
- The ESC must be switched on
^>page
146 and
fully functional (no ESC malfunction).
- The trailer connector must be properly secured
in the vehicle socket.
- The vehicle speed must be higher than approx.
60 km/h.
How trailer stabilisation works
In many cases, the driver can stabilise a swaying
trailer by manually braking the vehicle.
However, if the ESC detects that the trailer is
swaying and this is affecting the towing vehicle,
it will automatically brake the vehicle in order to
stabilise the trailer. The indicator
Lamp Hi
will
flash in the instrument cluster. If possible, do
not turn the steering wheel at this stage.
In order to warn traffic behind you, the brake
lights will come on during this automatic braking

operation.

A trailer may sway quite considerably without the
trailer stabilisation system intervening.
If the system for activating the trailer brake
lights is defective, this will be indicated in the in­
strument cluster display

Towing a trailer
Requirements for correct functioning of the
trailer stabilisation system
If these conditions are not met in
full,
the trailer
stabilisation system will only intervene to a
limi­

ted extent or not at all
>=>
A-
- The electrical connection between the towing
vehicle and the trailer must be functioning cor­
rectly.
- The load on the trailer must be properly se­

cured.

- The tyre pressures on both the vehicLe and the
trailer must be adapted to the load that is be­
ing carried.
- Where possible, operate the trailer with the
maximum permitted draw bar weight.
- The trailer overrun brake must be set correctly.
This is important to ensure that the trailer can
be braked correctly, to avoid the vehicle and
trailer "jack-knifing" and to prevent excess
braking of the trailer.
- At low outside temperatures, both the towing
vehicle and the trailer should be fitted with
winter tyres.
A WARNING
It is essential that you adjust your speed to
suit the weather, road and traffic conditions.
Do not let the trailer stabilisation system
tempt you into taking any risks when driving -
this can cause accidents.
- The ESC and trailer stabilisation system
can­

not defy the Laws of physics. This should be
kept in mind, particularly on slippery and
wet roads and when towing a trailer with a
light Load.
- The trailer stabilisation system is function­

al,
regardless of whether the trailer has a
mechanical overrun brake or not.
- The trailer stabilisation system is not always
able to detect swaying of trailers with a
light load and will therefore not intervene.
- A trailer can still "jack-knife" on slippery
roads with little grip, even if the towing ve­
hicle is equipped with the trailer stabilisa­
tion system.
-Trailers with a high centre of gravity may
even tip over before they start to sway
side­

ways.

-If
you
are not towing a trailer,
but
the
trail­

er socket is being used (e.g. for an illumina­
ted bicycle rack), the trailer stabilisation
system may be activated in extreme driving
conditions.
- Please note the additional information and
warnings
^>page
98, Driving tips.
Driving tips
Driving with a trailer always requires extra care.
Weight distribution
Try to avoid towing a loaded trailer with an unla­
den vehicle. If this cannot be avoided, drive extra
slowly to allow for the unbalanced weight distri­

bution.

Speed
Normally, you must not exceed 80 km/h when
towing a trailer or caravan. However, if the
trail­

er/caravan is equipped with a trailer stabilisation

system,
you can drive at max. 100 km/h. Please
observe any other regulations applicable in the
country in which you are travelling.
The stability of the car and trailer is reduced with
increasing speed. For this reason it is advisable
not to drive at the maximum permissible top
speed in unfavourable
road,
weather or wind
con­

ditions. This applies especially on a downhill gra­
dient.
You should always reduce speed immediately if
the trailer shows the slightest sign of swaying.
Never try to stop the swaying by accelerating fur­
ther.
Always brake in good time. If the trailer has an
overrun brake, apply the brakes gently at first
and then firmly. This will prevent the jerking that
can be caused by the trailer wheels locking.
Change down in good time before going down a
steep hill so
that
you can use the engine braking
effect to slow down the vehicLe.
Swaying and pitching can be reduced by attach­
ing an extra stabiliser to the trailer. It should •

WARNING

- When applying
the
brakes
to
clean
off
de­
posits
on the
pads and discs, select
a
clear,

road.
Be sure
not to
inconvenience
or
en­
danger other road users;
do not
risk an
acci­

dent.
- Never
let the car
coast with

(this can cause accidents).

(T)
CAUTION

- Never
let the
brakes "drag"
by
leaving your
foot on
the
pedal when you
do not
really
in­

tend
to
brake. This overheats
the
brakes,
re­

sulting
in
longer stopping distances
and

greater wear.
- Before driving down
a
long,
steep gradient,
it
is
advisable
to
reduce speed
and
select
a

lower gear.
In
this way you will make use
of

the engine braking effect and relieve
the

load
on the
brakes.
If
you
still have
to use

the brakes,
it is
better
to
brake firmly
at in­

tervals than
to
apply

wish
to
equip
the
car with accessories
such as a front spoiler
or
wheel covers,
it is

important that

General notes
Safety is the first priority
The safety features in your vehicle are harmon­
ised to provide you and your passengers with the
best possible protection in accident situations.
However, they can only be effective if you and
your passengers sit in the correct position and
adjust and use the safety equipment properly.
For these reasons, this chapter explains why
these safety features are so important, how they
can protect you, what you need to remember
when using them, and
how
you and your passen­
gers can gain the most benefit from them. There
are also a number of important safety warnings
which you and your passengers should always ob­
serve in order to minimise the risk of injury.
WARNING
- The information in this chapter is important
for the driver of the vehicle and all passen­

gers.
The other chapters in this manual

(and,
where applicable, in the other litera­
ture supplied with the vehicle) contain fur­
ther important notes which you should read
and observe for your own safety and that of
your passengers.
- Ensure that the complete vehicle wallet is
always in the vehicle. This is especially im­
portant when you lend or sell the vehicle to
others.

What factors can impair your safety?
Safety on the road is directly related to
how
you
drive, and can also be affected by the passengers
in the vehicle.
• The driver is responsible for the safety of the
vehicle and all its occupants. If your ability to
drive is impaired in any way, you endanger
yourself and other road users
,=>^.
Therefore:
• Do not let yourself be distracted by passengers
or by using a mobile phone, etc.

•
Never drive when your driving ability is im­
paired (by medication, alcohol, drugs, etc.).
• Obey all traffic regulations and speed limits
and always maintain a safe distance to the
vehi­

cle in front.

•
Always adjust your speed to suit the
road,
traf­
fic and weather conditions.

•
Take frequent breaks on long trips. Do not drive
for more than two hours without a stop.

•
If possible, avoid driving when you are tired or

stressed.
