Driving safety sys
tems50 Driving safety systems
In this section, you will find information abou t
the following driving safety systems:
R ABS ( Anti-lock Braking System)
R BAS ( Brake Assist System)
R ESP ®
( Electronic Stability Program)
i In wintry road conditions, always use win-
ter tyres (M+S tyres) and, where necessary ,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. G
Risk of accident
The risk of an accident is significantl y
increased by driving too fast. This is partic-
ularly the case when cornering on wet and
slippery roads and when driving too clos e
to the vehicle in front.
The driving safety systems described in thi s
section cannot reduce this risk or override
the laws of physics.
For this reason, always adapt your driving
style to suit the prevailing road and weather
conditions. Maintain sufficient distance
from other road users and objects on the
road. ABS (Anti-lock Braking System)
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from a speed of about 8 km/h
upwards, regardless of road surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently. G
Risk of accident
Do not depress the brake pedal severa l
times in quick succession (pumping) .
Depress the brake firmly and evenly. Pump-
ing the brake pedal reduces the braking
effect.
Braking If ABS intervenes when braking, you will fee
l
a pulsing in the brake pedal.
If ABS intervenes:
X Continue to depress the brake pedal wit h
force until the braking situation is over.
For full braking application:
X Depress the brake pedal with maximum
force. G
Risk of accident
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the
vehicle when braking and the braking dis-
tance may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are also deactivated. The
risk of your vehicle skidding is then
increased in certain situations.
You should therefore always adapt your
driving style to suit the prevailing road and
weather conditions . BAS (Brake Assist)
BAS operates in emergency braking situa -
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. Safety

Risk of accident
If BAS has malfunctioned, the braking sys-
tem remains available with full brake boost-
ing effect. However, braking force is not
automatically increased in emergency
braking situations and the stopping dis-
tance may increase. ES
P®
(Electronic Stability Program)
ES P®
monitors driving stability and traction,
i.e. power transmission between the tyres
and the road surface.
If ESP ®
detects that the vehicle is deviatin g
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. The engine output is also modified, if
necessary, to keep the vehicle on the desired
course within the scope of the laws of phys-
ics. ESP ®
assists the driver when pulling away
on wet or slippery roads. ES P®
can also sta-
bilise the vehicle during braking.
When ESP ®
intervenes, the vwarning
lamp flashes in the instrument cluster. G
Risk of accident
If the v warning lamp in the instrumen t
cluster flashes, proceed as follows: R
Do not deactivate ESP ®
under any cir -
cumstances .
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Adapt your driving style to suit the pre -
vailing road and weather conditions.
The vehicle could otherwise go into a skid.
ESP ®
cannot reduce the risk of an accident
if you drive too fast. ESP ®
cannot overrid e
the laws of physics .
! The ignition must be switched off (key in
position 0or Iin the ignition lock) if:
R the vehicle is being towed with the front
or rear axle raised
R you are having the handbrake checke d
on the brake dynamometer
Application of the brakes by ESP ®
could
otherwise destroy the brake system on the
front or rear axle.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly . To deactivate/activate ES
P® ESP
®
is activated automatically when the
engine is running.
It may be best to deactivate ES P®
in the fol-
lowing situations:
R when using snow chain s
R in deep sno w
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ES P®
will
otherwise not be able to stabilise the vehi -
cle if the vehicle starts to skid or a wheel
starts to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability
R Engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels produce a cutting effect for better
traction.
R traction control is still activated .
R ESP ®
still provides support when you
brake. Safety

Risk of accident
If the engine is not running, there is no
power assistance for the steering and
brakes. Steering and braking then take s
much more effort.
As a result, you might lose control of the
vehicle, cause an accident and injure your-
self and others.

Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any
objects in the driver's footwell. Make sure
that floormats or carpets are correctly
secured and that there is sufficient clear-
ance for the pedals. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. Thi s
could cause the drive wheels to lose thei r

the automatic transmission does not shift
down if you push the selector lever towards
D– while driving at too high a speed.
X To derestrict the shift range: press and
hold the selector lever towards D+until D
is shown once more in the display.
The automatic transmission shifts from the
current shift range directly to D.
X To select the most effective shift
range: press and hold the selector lever to
the left towards D–.
The automatic transmission will shift to a
range which allows ideal acceleration and
deceleration. To do this, the automatic
transmission will shift down one or more
gears. Shift ranges When the selector lever is in position
D, it is
possible to restrict or derestrict the shift
range for the automatic transmission .
X Briefly press the selector lever to the right
towards D+or to the left towards D–.

Risk of injury
Cruise control brakes automatically in
order to avoid exceeding the set speed. As
it does so, the brake pedal is depressed. Do
not place your foot under the brake pedal
as it could become trapped .
Storing and maintaining the current
speed You can store the current speed if you are
driving faster than 30 km/h.
X Accelerate the vehicle to the desired
speed.
X Briefly press the cruise control lever up
1 or down 4.
X Remove your foot from the accelerato r
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
i Cruise control may be unable to maintai n
the stored speed on uphill gradients. Th e
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically applying the brakes.
Vehicles with manual transmission: When selecting another gear, press the
accelerator pedal slightly to increase the
smoothness of the gear change.
When you depress the clutch pedal and
change to another gear, the engine speed
can increase slightly as long as no gear is
selected.
R
Always drive at adequate but not exces-
sive engine speeds .
R Change gear in good time.
R If possible, do not change down several
gears at a time.
Resuming the last speed stored G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for
the current situation. Otherwise, sudden
acceleration or braking could endanger yo u
or others.
X Briefly pull the cruise control lever towards
you 3.
X Remove your foot from the accelerato r
pedal.
Cruise control is activated and adjusts the
vehicle's speed to the last speed stored. Setting a speed X
Press the cruise control lever up 1for a
higher speed or down 4for a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached .
X Release the cruise control lever.
The new speed is stored.
i Cruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake ,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.
i Deceleration of the vehicle by means of
the cruise control lever is assisted by auto-
matic application of the brakes .

i The last speed stored is cleared when you
switch off the engine. Speedtronic
Speedtronic brakes automatically so that you
do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must shift to a lower gear
in good time or select shift range 1,2 or 3in
vehicles with automatic transmission*. In this
way you will make use of the braking effect of
the engine, which relieves the load on the
brake system and prevents the brakes fro m
overheating and wearing too quickly. If you
need additional braking, depress the brake
pedal repeatedly rather than continuously. G
Risk of accident
Never depress the brake pedal continu -
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. Thi s
could cause the drive wheels to lose thei r
grip and the vehicle could skid.
You can set a variable or permanent limit
speed:
R Variable for speed limits, e.g. in built-up
areas (Y page 113 )
R Permanent for long-term speed restric-
tions, e.g. for driving on winter tyres
( Y page 114 ) G
Risk of accident
