Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The ESP aids you maintain control of your vehicle in situations in borderline driving situations such as when negotiating a curve too fast. The risk of skidding is reduced and your vehicle thus offers greater driving stability depending on the conditions of the road surface. This occurs at all speeds. The following systems are integrated into the electronic stability programme:•
Electronic Differential Lock (EDL),
•
Traction control system (TCS),
•
Antilock brake system (ABS),
•
Brake Assist.
Operating principle The ESP switches on automatically when the engine is started and then conducts a self-test. The ESP control unit processes data from the individual systems. It also processes additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin
g pressure and the steering angle.
The direction which the driver wishes to ta
ke is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual behaviour of the vehicle. If differences exis
t, such as the vehicle beginning to skid,
the ESP will automatically brake the appropriate wheel. The car is stabilised again by the forces which take effect when the wheel is braked. Intervention into the brake system takes place primarily on the outer front wheel of a vehicle which tends to oversteer (tendency for the rear of the vehicle to break away) while occurs this is on the inner re
ar wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied by noises. The ESP operates in combination with the ABS
⇒page 135, “Antilock brake system
(ABS)*”. If there is a fault in the ABS system, the ESP also does not operate. The ESP warning light
⇒page 33 lights up in the instrument cluster when there is a
fault on the ESP. Switching off You can switch the ESP off and on again
as you wish, by pressing the button
⇒ fig. 139
. The ESP warning light
⇒page 33 lights up in the instrument cluster
when the ESP is switched off. The ESP should normally always be switched
on. It may be good practice in certain
exceptional cases, such as when you wish
to have wheel slip, to switch off the
system. Examples:

Traction control system (TCS) The traction control system prevents
the driven wheels from spinning
when accelerating.General The TCS makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditio
ns of the road surface are unfavourable.
Operating principle The TCS switches on automatically when th
e engine is started and then conducts a
self-test. The system monitors the speeds of the driven wheels with the aid of the ABS sensors. If the wheels are spinning, the force transmitted to the road surface is automatically adapted by redu
cing the engine speed. Th
is occurs at all speeds.
The TCS operates in combination with the ABS
⇒page 135, “Antilock brake system
(ABS)*”. The TCS will not function if a fault exists in the ABS system. The TCS warning light
⇒page 33 lights up in the instrument cluster when there is a
fault on the TCS. Switching off You can switch the TCS off and on again
as you wish by pressing the button
⇒ fig. 140
. The TCS warning light
⇒page 33 lights up in the instrument cluster
when the TCS is switched off.
The TCS should normally always be switched on. It may be good practice in certain exceptional cases, such as when you wish
to have wheel slip, to switch off the
system. Examples:•
when driving with snow chains
•
when driving in deep snow or on a loose surface
•
when it is necessary to rock a vehicle when it has become stuck.
then you should switch on the TCS again.
WARNING
You should always adjust your style of driving to the conditions of the road surface and the traffic situation. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the TCS. Differing rolling circumferences of the tyres can lead to an undesirable reduction in the engine output.•
Changes to vehicle (e.g. on engine, on
the brakes, on chassis or another combi-
nation of tyres and wheels) can in
fluence the function of the TCS

Particularly if you drive a great deal in towns and over short distances or if you adopt a sporty style of driving, it may be neces- sary to have the thickness of the brake
pads inspected at a specialist garage
between the service inspections.

Technical Data
Antilock brake system (ABS)*ABS prevents the wheels locking when braking.General The ABS contributes significan
tly to enhancing the active
safety of your vehicle.
Compared to a vehicle not fitted with the ABS brake system, you are able to retain optimal steering ability even during a fu
ll brake application on a slippery road
surface because the wheels do not lock up. You must not expect, however, that the br
aking distance will be shorter under all
circumstances as a result of the ABS. Th
e braking distance for example on gravel
and fresh snow, when you should anyway be driving slowly and cautiously, will be longer. Operating principle The brake pressure will be reduced on a wheel which is rotating at a speed which is too low for the speed of the vehicle and tend
ing to lock. This control cycle is notice-
able from a
pulsating movement of the brake pedal
which is accompanied by
noises. This is consciously intended to provide the driver with the information that the wheels are tending to lock (ABS control range). You must always keep the brake pedal depressed to enable the ABS to optima
lly control the brake application in this
braking range. Never interrupt the application of the brakes!
WARNING
•
The ABS can also not overcome the physic
al limits of your
vehicle. Please
do not forget this, particularly when driv
ing on icy or wet road surfaces. If the
ABS is operating within the control ra
nge, adapt your speed immediately to
the conditions of the road surface an
d the traffic situation. The increased
safety offered by the ABS must not tempt you to take greater risks than otherwise - risk of an accident!•
The normal braking system is
still fully functional if there is an ABS fault.
Visit a specialist garage as
quickly as possible and adju
st your style of driving
to take account of the ABS fault in the meantime since you will not know the extent of the fault and in how far
the braking efficiency is affected.
Note

⇒page 179,
“Accessories, changes and replacement of parts”.Brake Assist*During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the braking force and thus makes it possible to rapidly produce the pressure required in the brake system. The majority of drivers do apply the brakes in good time in dangerous situations, but do not depress the brake pedal with suff
icient pressure. Consequently, it is not
possible for the vehicle to achieve its maximum deceleration and the vehicle covers a greater distance than necessary. The Brake Assist is activated by the very quick operation of the brake pedal. In such cases, a much greater braking pressure ex
ists than during a
normal brake applica-
tion. This makes it possible, even with a relatively low resistance of the brake pedal, to produce an adequate pressure in the brake system in the shortest possible time, which is required for maximum decelerati
on of the vehicle. You must apply the
brake pedal firmly and
hold it in this position in order to achieve the shortest
possible braking distance. The Brake Assist is able to help you achi
eve a shorter braking distance in emergency
situations by rapidly producing the pressure
required in the brake system. It fully
exploits the attributes of the ABS. After yo
u release the brake peda
l, the function of
the Brake Assist is automatically switched off and the brakes operate in the normal way.
WARNING
•
The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the br
aking distance required.

Driving and the EnvironmentThe first 1 500 kilometres and then afterwardsA new engine The engine has to be run in during the first 1 500 kilometres.Up to 1 000 kilometres – Do not drive faster than 3/4 of the
maximum speed of the gear in use,
that is 3/4 of the maximum permissible engine speed.
– Do not use full throttle.– Avoid high engine revolutions. – Do not tow a trailer. From 1 000 up to 1 500 kilometres – Increase the power output of the engine
gradually
up to the full
speed of the gear engaged, that
is up to the maximum permissible
engine revolutions.
During the first operating hours the engine
has higher internal
friction than later
until all of the moving parts have harmonized. The driving style which you adopt during the first approx.1 500 kilometres
plays a decisive part in the success of
running in yo
ur vehicle.
You should not drive at unnecessarily
high engine revolutions
even after the
running-in period is
complete. The maximum permissib
le engine spee
d is marked
by the beginning of the red zone on the scale of the revolutions counter. Shift up into the next higher gear on a vehicle
fitted with manual gearbox before the red
zone is reached.
Extremely
high engine revolutions are automatically governed, by
the way. For a vehicle fitted with a manual gearbox
the converse situation also applies: Do
not drive at engine revolutions which are
too low
. Shift down as soon as the engine
is no longer running smoothly.
Caution
All the speed and engine revolution figure
s apply only when the engine is at its
normal operating temperature. Never rev up
an engine which is cold, neither when
the vehicle is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a higher gear as early as possible are ways to minimise fuel consumption and operating noise levels and protects the environment.New tyresNew tyres have to be “run in” since they do
not offer optimal grip at first. You should
take account of this fact for the first 500 kilometres and drive particularly carefully.New brake padsAllow for the fact that new brake pads do
not achieve their full braking efficiency
until approximately 200 kilometres. New brake pads must be first “run in” before they develop their optimal friction force.
You can, however, compensate for this
slightly reduced braking force by increasing the pressure on the brake pedal. This guideline also applies to any new
brake pads installed at a future date.
During the running-in period, you should
avoid excessive stresses on the brakes.
This includes, for example, violent braking,
particularly from very high speeds, and
also when crossing mountain passes.

number of tips on how to protect the environment and at the same time save money. The fuel consumption can naturally also be
influenced by factors which are beyond
the driver's control. It is,
for example, normal for the fu
el consumption to increase
in winter and under worsened
conditions such as poor road conditions, towing a
trailer, etc. The technical requirements for low fuel
usage and economic efficiency of the
vehicle have already been built into the ve
hicle at the works.
Special attention has
been given to minimising ne
gative effects on the environment. It is necessary to
take note of the guidelines given in this
chapter in order to make best use of these
characteristics and to maintain their effectiveness. The optimal engine speed should be obtained when accelerating, in order to avoid a high fuel consumption an
d resonance of the vehicle.
Looking ahead when driving A vehicle's highest fuel consumption occurs it accelerates.Avoid accelerating and brakin
g unnecessarily. If you drive
with forsight you will not
need to brake so often and will also then
not have to accelerate so much. Let your
vehicle coast to a stop, for example, if this
is possible, when you see that the next
set of traffic lights is at red.
Shifting gears and saving energy Shifting up early saves on fuel.Manual gearbox – Drive no more than about one length of your vehicle in first gear. – Always shift up into the next higher gear at approx. 2 000 to 2 500 revs.An effective way of achieving good
fuel economy is to shift up
early
. You will
consume more fuel if you drive at unnecessa
rily high revolutions in any given gear.
The
⇒fig. 141
shows the ratio of fuel consumption to the speed of your vehicle in
the relevant gears. Fuel consumption in 1st
gear is the highest and in 5th gear is the
lowest.

Avoid driving short distances Short distances result in an above-average high fuel consumption.– Avoid driving a distance of no more than 4 km if the engine is cold.The engine and catalytic converter mu
st first have reached their optimal
operating
temperature
in order to effectively reduce fu
el consumption and pollutant emis-
sions. The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediately after starting. Fuel co
nsumption drops to 10 litres/100 km after just 1 kilometre. The
engine reaches its operating temperat
ure (outside temperature and engine
dependent) only after about
4 to 10
kilometres and the fuel consumption then
stabilizes. You should therefore avoid driving short distances whenever possible. An important factor in this connection is also the
ambient temperature
. The
⇒ fig. 143
shows the different fuel consumptions for the same distance, on the one
hand at +20°C and on the other hand at
-10°C. Your vehicle has a higher fuel
consumption in winter than in summer.Checking tyre inflation pressures Tyres which are correctly inflated save fuel.Always ensure that your tyres are inflated
to the correct pressure at all times. The
rolling resistance will be increased if the tyre filling pressure is too low. This will not
only increase fuel consumption but also
tyre wear and the driving behaviour will
worsen. Always check the inflation pressure of the tyres when
cold
.
Do not drive with
winter tyres
all year round for this costs about 10 % more fuel.
Winter tyres are also louder.No unnecessary ballast Transporting ballast costs fuel.The fact that every kilogram of extra
weight
increases your fuel consumption
means that it is worth taking a look in the luggage compartment to avoid trans- porting any unnecessary ballast. It is particularly in town traffic, when one
is accelerating quite often, that the vehicle
weight will have a significant effect upon
the fuel consumption. A rule of thumb
here is that an increase in weight of 100
kilograms will cause an increase in fuel
consumption of about 1
litre/100 kilometres.
You may frequently also leave a
roof rack fitted
on just out of convenience,
although you no longer need it. The incr
eased aerodynamic drag of your vehicle
causes it to use about 10% more fuel th
an normal at a speed of 100 - 120 km/h,
even when you are not carr
ying a load on the roof.
Saving electricity Generating electricity costs fuel.– Switch off electrical components as
soon as you no longer need them.
When the engine is running, the alternator
generates and supplies
electrical power.
The greater the load on the alternator as a result of having a large number of elec-trical components switched on, the more
fuel will be consumed for operating the
alternator.
