\3 Driving safety systemsIn this section, you will find information
about the following driving safety sys-
tems: \4
ABS (A
ntilock B
rake S
ystem)
\4
BAS (B
rake As
sist)
\4
ESP
® (E
lectronic S
tability P
rogram)
\4
ASR (acceleration skid control)
\4
EBV (electronic brake force distribu-
tion)
iThe maximum effect of ABS, BAS,
ESP
®, ASR and EBV can only be
achieved if you:
\4
always drive with the correct tire
pressures adjusted according to
the load (
\2
page 361)
\4
use winter tires (M+S tires) in
wintry conditions, with snow
chains if necessary
Warning
G
There is an increased risk of an accident if
you:\4
drive too fast, in particular when corner-
ing and on a wet or slippery road surface
\4drive too close to the vehicle in front
The driving safety systems described in
this section cannot reduce this risk and
are unable to override the laws of physics.
Always adapt your driving style to the pre-
vailing road and weather conditions, and
maintain an adequately safe distance
from other road users as well as any ob-
stacles on the road.

ABS regulates the brake pressure in
such a way that the wheels do not lock
when you brake. This allows you to con-
tinue steering when braking.
ABS works from a speed of about 3 mph
(5 km/h) upwards, regardless of road
surface conditions.
ABS works on slippery surfaces, even
when you only brake gently.There is a malfunction if the
-
indica-
tor lamp is permanently lit while the en-
gine is running (
\2
page 466).
Despite this, the normal driving and
braking functions remain available.
iOnly use wheels with the recom-
mended tire sizes (
\2
page 623), oth-
erwise the driving safety systems will
not work correctly.
Antilock Brake System (ABS)
Warning
G
Do not depress the brake pedal several
times in quick succession (pumping). De-
press the brake firmly and evenly. Pump-
ing the brake pedal may reduce the
braking effect.

BrakingIf ABS intervenes during braking, you will
feel the steering wheel vibrate gently
and the brake pedal pulsate.
If ABS intervenes: \1
Continue to depress the brake pedal
firmly until the braking situation is
over.
For full brake application:
\1
Depress the brake pedal with maxi-
mum force.Brake Assist operates in emergency
braking situations. If you depress the
brake pedal quickly, BAS automatically
increases the brake pressure, thereby
reducing the stopping distance.
\1
Keep the brake pedal firmly de-
pressed until the emergency braking
situation is over.
ABS prevents the wheels from lock-
ing.
When you release the brake pedal, the
brakes will work as normal again. BAS is
deactivated.
Warning
G
Always adapt your driving style to the pre-
vailing road and weather conditions, and
maintain an adequately safe distance
from other road users as well as any ob-
stacles on the road.
If ABS malfunctions, the wheels could
lock when you brake. This means that the
steerability of the vehicle is restricted
during braking and the stopping distance
may increase. If ABS is deactivated due to
a malfunction, BAS is also deactivated.

Warning
G
ESP
® remains active despite ASR having
been deactivated and carries out braking
interventions if this is necessary to im-
prove driving stability. Thev warning
lamp flashes.
If ASR is deactivated, there is an in-
creased risk that the brake system of your
vehicle could overheat and be damaged
when subjected to high loads for a long
period of time. A hot brake system also in-
creases the stopping distance.
For this reason, only deactivate ASR when
it is absolutely necessary.

your vehicle are described on the follow-
ing pages:\4
Cruise control* (

you can use to control the speed of
your vehicle
\4
Parktronic system*, which is an aid

road users (
\2
page 271)The ABS, BAS, ESP
®, ASR and EBV driv-
ing safety systems are described in the
"Driving Safety Systems" section
(
\2
page 33).
Cruise control maintains the speed of
the vehicle for you.
Use cruise control if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period.
You can set any speed above 20 mph
(30 km/h) in 1-mph increments (1-km/
h increments).Cruise control*
iThe increments for setting speed and
the threshold values for switching on
or automatically switching off cruise
control depend on the digital speed-
ometer setting, mph or km/h
(\2
page 165).

Warning
G
Parktronic is only an aid and may not de-
tect all obstacles. This system does not
relieve you of the need to pay attention.
You are always responsible for safety and
must continue to pay attention to your im-
mediate surroundings when parking and
maneuvering. Otherwise, you could en-
danger yourself and others.
Warning
G
Make sure that no persons or animals are
in the maneuvering range of the vehicle.
They could otherwise be injured.

\1
Always attach the lashing net or
tarps to all available lashing points.
While doing so, make sure that the
mounting hooks cannot open unin-
tentionally.
Warning
G
Do not carry out any modifications or repairs
to the lashing points, the lashing eyes or the
lashing materials. The load or the lashing
points could accidentally come loose and
cause serious injury to you or others as well
as damage to property.Distribute loads evenly between the lash-
ing points or lashing eyes.
Observe the loading guidelines.iLoose loads should be secured with
an approved lashing net or tarp.
!
CAUTION
Observe the data on the maximum
load-bearing capacity of the individu-
al lashing points
(\2
page 629).
During full-braking applications, for
example, forces can be involved that
are much greater than the weight
force of the load.
Always use several lashing points in
order to distribute force absorption,
and make sure that the lashing
points have an equal load.
iIf your vehicle has load rails in the
floor, you should position locking
rods immediately in front of and be-
hind the load. The locking rods ab-
sorb possible shifting forces directly.
