Electronic stabilisation
control (ESC)
Description
The electronic stabilisation control (ESC) increa­
ses the car's stability. It reduces the tendency to
skid and improves the stability and roadholding
of the vehicle. The ESC detects critical handling
situations, such as understeer, oversteer and

wheelspin
on the driven wheels. It stabilises the
vehicle by braking individual wheels or by reduc­
ing the engine torque. The indicator
lamp^
in
the instrument cluster starts flashing as soon as
the ESC intervenes.
The following systems are integrated in the ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under
braking until the vehicle has reached a virtual

standstill.
You can continue to steer the vehicle
even when the brakes are on
full.
Keep your foot
on the brake pedal and do not pump the brakes.
You will feel the brake pedal puLsate while the
anti-lock brake system is working.
Brake assist system
The brake assist system can shorten the braking
distance. The braking force is automatically boos­
ted if
you
press the brake pedal quickly in an
emergency. You must keep pressing the brake
pedal until the danger has passed. On
vehides

with adaptive cruise control*, the response of the
brake assist system will be more sensitive if you
are too close to the vehicLe in front.
Traction control system (ASR)
In the event of
wheelspin,
the traction control
system reduces the engine torque to match the
amount of grip available. This helps the car to
start moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes the
spinning wheel and directs the power to the
oth­

er driven wheel (or wheels on quattro* versions).
This function is not available at high speeds.
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automatically
if subjected to excessive loads. The vehicLe can
still be driven. The EDL will switch on again auto­
matically when the brake has cooled down.
Steering recommendation
The ESC helps to stabilise the vehicle by changing
the steering wheel torque.
Trailer stabilisation system
Applies to: vehicles with trailer stabilisation system
Trailers have a tendency to sway. If the
ESC
de­
tects that the trailer is swaying and this is affect­
ing the towing vehicLe, it will automatically brake
the vehicle in order to stabilise the trailer

^>page
97.
Selective wheel torque control
Selective wheel torque control intervenes when
cornering by braking the wheel(s) on the inside of
the bend individually as required. This enables
precision cornering.
Multicollision brake assist system
The "multicollision brake assist system" can help
to reduce the risk of skidding and further
colli­

sions during an accident. If the airbag control
unit detects that
a
collision has taken place up­
wards of
a
certain speed, the vehicle is braked by
the
ESC.

The vehicle will not be braked automatically if:
- the driver presses the accelerator,
- or the
ESC,
the brake system or the vehicle's
electrical system are not fully functional.
WARNING
- The grip provided by the ESC and the inte­
grated systems is still subject to the physi­
cal limits of adhesion. Always bear this in

mind,
especially on wet or sLippery roads. If
you notice the systems cutting in, you
should reduce your speed immediately to
suit the road and traffic conditions. Do not

let
the extra safety provided tempt you into
taking any risks when driving - this can
cause accidents.
145

Intelligent technology
Remember that the accident risk always in­
creases
if
you
drive fast, especially
in
cor­
ners
or
on a wet
or
slippery
road,
or if
you
follow too close behind the vehicle in front
of
you.
Please bear
in
mind that even
the

ESC
and
the
integrated systems cannot
compensate
for
the increased accident risk.
When accelerating
on
a uniformly slippery
surface
(for
instance
all
four wheels on
ice

or snow), press the accelerator gradually
and carefully. The driven wheels may other­
wise start
to
spin
(in
spite
of
the integrated
control systems), which would impair the
car's stability and could lead
to
an accident.
© Note
The ABS and ASR systems can only work
properly
if
a 11
four tyres have a similar de­
gree
of
wear. Any differences
in the
rolling
radius
of
the tyres can cause the system
to

reduce engine power when this
is not
de­

sired.

The systems can make noises when they in­
tervene.

is switched on automatically when

Seat belts
Why is it so important to
use seat belts?
Seat belts provide effective protection
The common belief that passengers can brace
their weight with their hands in a minor collision
is false.

Fig.
215 Driver with correctly positioned seat belt - good
protection if the brakes are applied suddenly
It is an established fact that seat belts provide
good protection in accidents. Therefore wearing
a seat belt is required by law in most countries.
When worn correctly, seat belts hold the occu­
pants in the best position for maximum protec­
tion
^>Fig.
215. The seat belts are capable of ab­
sorbing much of the kinetic energy which is
gen­

erated in a collision. They also help to prevent
uncontrolled movements which could Lead to se­
vere injuries
^>page
275, Important safety
notes when using seat belts.
If they wear the seat belts correctly, the passen­
gers benefit greatly from the ability of the belts
to reduce the kinetic energy gradually. The front
crumple zones and other passive safety features
(such as the airbag system) are also designed to
absorb the kinetic energy generated in a
colli­

sion.
Taken together, all these features reduce
the forces acting on the occupants and conse­
quently the risk of injury.
Although these examples are based on a frontal

collision,
the physical principles involved are the
same in other types of accidents. This is why it is
so important to put on the seat belts before ev­
ery trip - even when "just driving around the cor­
ner". Ensure that your passengers wear their seat
belts as well
^A-

Seat belts worn correctly have been shown to be
an effective means of reducing the potential for
injury and improving the chances of survival in a
serious accident
^>page
276, Forces acting in a
collision.
For information on how children can travel safely
in the car refer to
^>page
267, Child seats.
A WARNING
- Seat belts must be put on before every trip -
even when driving in town. This also applies
to the rear passengers - risk of injury!
- During pregnancy, women should always
ensure they wear a seat belt. The best way
to protect the unborn child is to protect the
mother
^>page
278, Wearing and adjust­
ing the seat belts during pregnancy.
Important safety notes when using seat
belts
There are a number of safety points concerning
the seat belts which you should remember. This
will help to reduce the risk of injury in an
acci­

dent.
A WARNING
- The seat belts can only provide maximum
protection if the seats are adjusted properly

^>page
58, Front seats.
- To ensure proper protection, it is important
to wear the seat belts in the correct position

^>page
277, How to wear seat belts prop­

erly.
Ensure that the seat belts are worn ex­
actly as recommended in this chapter. Belts
which are
not
worn properly can increase
the risk of injury in accidents considerably.
- Do not allow the seat belt to become twis­
ted or jammed, or to rub on any sharp
edges.
- Never allow two passengers (even children)
to share the same seat belt. It is especially
dangerous to place a seat belt over a child
sitting on your lap.
275

Seat belts
- Do not wear the belt over hard or fragile ob­
jects (such as glasses or pens, etc.) because
this can cause injuries.
- Loose, bulky clothing (such as an overcoat
over
a
jacket) impairs the proper fit and
function of the belts.
- The belts must be kept clean, otherwise the
retractors may not work properly

•=>
tab. Cleaning the interior on page 314.
- The slot in the seat belt buckle must not be
blocked with paper or other objects, as this
can prevent the latch plate from engaging
properly.
-The latch plate of the belt must always be
engaged in the correct buckle for that seat,
otherwise the belt will not be fully effective.
- Check the condition of the seat beLts at
reg­

ular intervals. If
you
notice that the belt

webbing,
fittings, retractor mechanism or
buckle of any of the belts is damaged, the
belt must be replaced by a qualified work­

shop.

- The seat belts must not be removed or
modified in any way. Do not attempt to re­
pair
a
damaged belt yourself.
- Seat belts which have been worn in an
acci­

dent and stretched must be replaced by a
qualified workshop. The belt anchorages
should also be checked.
Forces acting in a
collision
The physical principles involved in a frontal
impact

Very
large forces are generated during a
colli­

sion; these forces have to be absorbed.

Fig.
216 Passengers of
a
vehicle which is headed for a
brick
wall.
They are not using seat belts.

Fig.
217 The vehicle crashes into the wall
The physical principles involved in a frontal
colli­

sion are relatively simple:
Both the moving vehicle and the passengers pos­
sess energy, which is known as "kinetic energy"

^>Fig.
216. The amount of "kinetic energy" de­
pends on the speed of the vehicle and the weight
of the vehicle and passengers. The higher the
speed and the greater the weight, the more ener­
gy there is to be absorbed in an accident.
The most significant factor, however,
is
the
speed of the vehicle. If the speed doubles from
25 km/h to 50 km/h, for example, the kinetic en­
ergy increases by
a
factor of four. Because these
passengers are not restrained by seat belts, the
entire amount of kinetic energy has to be absor­
bed
at
the point of impact
^>Fig.
217. This would
result in serious or potentially fatal injury.

The

When fully inflated, the airbags reduce the risk
of head or chest
injury.

locations of the airbags are marked with the
word "AIRBAG".
In conjunction with the three-point seat belts,
the front airbags give additional head and chest

the event of
a
severe frontal collision

230 Front airbags in inflated condition
The driver's and front passenger's airbag are
trig­

gered in certain frontal collisions
^>Fig.
230. Fur­
ther airbag systems may also be triggered, de­
pending on the circumstances.
When the system is triggered, the airbags fill
with a propellant gas and open out in front of the
driver and front passenger
^>Fig.
230. In order to
provide the desired extra protection in an
acci­

dent, the airbags have to inflate extremely rapid­
ly (within fractions of
a
second). The fully de­
ployed airbags cushion the forwards movement
of the front occupants and help to reduce the risk
of injury to the head and the upper part of the
body.
Special openings in the airbag allow the gas to
escape at
a
controlled rate to restrain the for­
ward movement of the occupant's head and tor­

so.
Once the impact has been absorbed, the air-
bag deflates sufficiently for the front occupants
to see forward.

- Make sure you never spill fuel in the
vehi­

cle or in the luggage compartment. Fuel
vapour is explosive - danger to life!
© Note
(7) CAUTION
- If any fuel is spilt onto the vehicle, it should
be removed immediately as it could other­
wise damage the paintwork.
- Never run the tank completely dry. If there
is an irregular fuel supply, misfiring can oc­
cur. As a result unburnt fuel can enter the
exhaust system and cause damage to the
catalytic converter(s).
- Applies to vehicles with diesel engine: When
filling the fuel tank after having run it com­
pletely dry, the ignition must be switched
on for at least 30 seconds before the engine
is started. When you then start the engine it
may take longer than normal (up to one mi­
nute) for the engine to start firing. This is
because air needs to be bled from the fuel
system while starting.
® For the sake of the envir
Do not try to put in more fuel after the auto­
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm.

(T)
Note
Applies to: vehicles with diesel engine
Diesel vehicles are equipped with an incorrect
fuelling protection
system1).
This system en­
sures that the tank can only be fuelled from a
diesel filler nozzle.
- If the filler nozzle is old, damaged or too

small,
it may not be able to open the pro­
tection mechanism on the fuel tank. In this

case,
try turning the filler nozzle before in­
serting it in the fuel filler neck, use a differ­
ent filling pump or seek professional assis­

tance.

- The protection mechanism will not open if
you try to add fuel from a spare fuel canis­
ter. You can get round this simply by adding
the diesel fuel slowly.
