Operating safety
Important safet yn otes
G WARNING
If you do not have the prescribed service/
maintenanc ew ork or any required repairs
carried out, this can result in malfunctions or
system failures. There is ar isk of an accident.
Always have the prescribed service/mainte-
nanc ew ork as well as any required repairs
carried out at aq ualified specialist workshop.
G WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is ar isk
of fire.
When driving off road or on unpaved roads,
chec kt he vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
G WARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardiz et he operatin gs afety of
the vehicle. There is an increased risk of an
acciden ta nd injury.
Never tamper with the wiring as well as elec-
tronic component sort heir software. You
should have all work to electrical and elec-
tronic equipment carried out at aq ualified
specialist workshop. ! There is ar isk of damage to the vehicle if: R
the vehicle becomes stuck ,e .g. on ah igh
curb or an unpaved road R
you drive too fast over an obstacle, e.g. a
curb or ah ole in the road R
ah eavy objec ts trikes the undercarriage or
parts of the chassis
In situation sl ike this, the body, the undercar-
riage, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed
to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust
system, they can catc hf ire.
In such situations, have the vehicle checked
and repaired immediately at aq ualified spe-
cialist workshop. If on continuin gy our jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult aq ualified spe-
cialist workshop.

good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and
weather conditions and maintain as afe distance
from the vehicle in front .D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and tires"
section ( Y
page 255).
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)
General information ABS regulates brake pressure in such aw ay that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The % ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from as peed of about 5m ph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
i Observe the "Important safety notes" sec-
tion ( Y
page 54).
G WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally ,f urther driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at aq ualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp ( Y
page 204) and dis- play messages which may be shown in the
instrument cluster ( Y
page 179).
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over. X
To make af ull brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a
reminder to take extr ac are while driving.
BAS (Brake Assist System)
General information BAS operates in emergenc yb raking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
i Observe the "Important safety notes" sec-
tion ( Y
page 54).
G WARNING
If BAS is malfunctioning, the braking distance
in an emergenc yb raking situation is
increased. There is ar isk of an accident.
In an emergenc yb raking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking X
Keep the brake pedal firmly depressed until
the emergenc yb raking situation is over.
ABS prevent st he wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.Driving safety systems 55

dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Therefor en ever leave
the engin er unning in enclosed spaces with-
out sufficien tv entilation.
Certain engin es ystems are designed to keep
the level of poisonous component sine xhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .A lways have
work on the engin ec arried out at aq ualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Ben zC enter for this purpose. Work relevant to
safety or work on safety-related systems in par-
ticular must be carried out at aq ualified spe-
cialist workshop.
The engin es ettings must not be changed under
any circumstances. Furthermore, all specific
servic ew ork must be carried out at regular
intervals and in accordance with the Mercedes-
Ben zs ervic er equirements. Details can be found
in the Maintenanc eB ooklet.

Parking Guidance
Important safety notes Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to measure
the road on both sides of the vehicle. As uitable
parking space is indicated by the parking sym-
bol. You receive steering instructions when
parking. You may also use PARKTRONIC
( Y
page 149).
Parking Guidance is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. When maneuvering, parking or
pulling out of ap arking space, make sure that
there are no persons, animals or object sint he
area in which you are maneuvering.
G WARNING
If object sa re located above the detection
range, Parking Guidance may provide steering
instructions too soon. You may cause ac olli-
sion as ar esult. There is ar isk of an accident.
If object sa re located above the detection
range, stop and switch off Parking Assist. ! If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at as harp
angle. Otherwise, you may damage the
wheels or tires.
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Parking Guidance may also display spaces not
suitable for parking, e.g.: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces
Use Parking Guidance for parking spaces: R
that are paralle ltot he direction of travelR
that are on straight roads, not bends R
that are on the same level as the road, i.e. not
on the pavement, for example. Parking Guid-
ance may not detect flat curbs
Parking tips: R
On narrow roads, drive as close to the parking
space as possible. R
Parking spaces that are littered or overgrown
might be identified or measured incorrectly. R
Parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.152
