produce an undesired effect on other
systems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
Contact
an
authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function when the
engine is running. You should therefore never
turn off the engine while driving. G
WARNING
Heavy
blows against the vehicle underbody or
tires/wheels may cause serious damage and
impair the operating safety of your vehicle.
Such blows can be caused, for example, by
running over an obstacle, road debris or a
pothole.
If you feel a sudden significant vibration or
ride disturbance,

or you suspect that damage
to your vehicle has occurred:
R turn on your hazard warning flashers.
R slow down carefully.
R drive with caution to an area which is a safe
distance from the road.
Inspect the vehicle underbody and tires/
wheels for possible damage. If the vehicle
appears unsafe, have it towed to the nearest
authorized Mercedes-Benz Center or other
qualified maintenance or repair facility for
further inspection or repairs. On-board diagnostics interface
G
WARNING
If you connect equipment to the on-board
diagnostics interface, it can affect the
operation of the vehicle systems. This can
impair the operating safety of your vehicle
while driving. There is a risk of accident. Do not connect any equipment to the on-
board diagnostics interface.
G
WARNING
Loose equipment or equipment cables which
are connected to the on-board diagnostics
interface can obstruct the area around the
pedals. The

equipment or the cables could get
between the pedals in the event of sudden
braking or acceleration. You may then no
longer be able to brake, operate the clutch or
accelerate as intended. There is a risk of
accident.
Do not attach any equipment or cables in the
driver footwell.
Connecting equipment to the on-board
diagnostics interface can lead to emissions
monitoring information being reset. This may
lead to the vehicle failing to meet the
requirements at the next special emissions
test or main inspection.
If the engine is switched off and equipment
which is connected to the on-board
diagnostics interface is used, the starter
battery may discharge.
The on-board diagnostics interface is only
intended for the connection of diagnostic
equipment at a qualified specialist workshop. Qualified specialist workshop
An authorized Mercedes-Benz Center is a
qualified specialist workshop. It has the
necessary specialist knowledge, tools and
qualifications to correctly carry out the work
required on

your vehicle. This is especially the
case for work relevant to safety.
Observe the notes in the Maintenance
Booklet.
Always have the following work carried out at
an authorized Mercedes-Benz Center:
R work relevant to safety
R service and maintenance work
R repair work20

Driving safety systems overview
In this

section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock Braking System)
R BAS ( Brake Assist System) R
ESP ®
(Electronic Stability Program)
R EBD ( electronic brake force distribution) Important safety notes
G
WARNING
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the natural

laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user's safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear. G
WARNING
The ABS, the BAS, and the ESP ®
switch off
when the differential locks are switched on.
When the ABS, the BAS, and the ESP ®
are
switched off
R wheels may lock during hard braking
R steering capabilities are reduced Driving safety systems
53Safety
Z

R
braking distance is increased
R vehicle stability in standard driving
maneuvers is increased
Make sure
the differential locks are switched
on at all times except when driving off-road
for example. Switch on the differential locks
immediately when returning from off-road
driving.
i Please note that the driving safety
systems described only work as effectively
as possible if there is adequate contact
between the tires and the road surface. Pay
particular attention to the information
regarding tires, recommended minimum
tire tread depths, etc. in the "Wheels and
tires" section (Y page 242).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible. ABS (Anti-lock Braking System)
Important safety notes G
WARNING
Observe "Important safety notes"
(
Y page 53).
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
ABS operates above a speed of about
5 mph(8 km/h) regardless of road-surface
conditions, provided

the differential locks are
not active. ABS works on slippery surfaces,
even when you only brake gently. G
WARNING
If
the ABS malfunctions, other driving systems
such as

the BAS or the ESP ®
are also switched
off. Observe indicator and warning lamps that may come on as well as messages in the
multifunction display that may appear.
If
the

ABS malfunctions, the wheels may lock
during hard braking, reducing the steering
capability and extending the braking distance.
The ! warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Braking If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
X
If
ABS intervenes:
continue
to depress the
brake pedal with force until the braking
situation is over.
X To make a full brake application:
depress the brake pedal with full force.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving. G
WARNING
Do
not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
Off-road ABS If the LOW shift range (
Y page 145) is
selected on
the transfer case, an ABS system
specifically suited to off-road terrain is
activated.
At speeds below 37 mph(60 km/h), the front
wheels lock periodically when braking. The
digging-in effect achieved in the process
reduces the stopping distance on off-road
terrain. This limits steering capability. BAS (Brake Assist System)
i Observe the "Important safety notes"
section ( Y
