Important safety notes G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident. Driving

Braking
Important safety notes G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on a slippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting
early to a lower gear. This allows you to take
advantage of the engine braking effect and
helps avoid overheating and excessive
wear of the brakes.
When you take advantage of the engine
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road
surface. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Benz warranty.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately.
Drive on for a short while. This allows the
airflow to cool the brakes more quickly. Wet roads If you have driven for a long time in heavy rain
without braking, there may be a delayed
reaction from the brakes when braking for the
first time. This may also occur after the
vehicle has been washed or driven through
deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the
vehicle washed, brake firmly while paying
attention to the traffic conditions. This will
warm up the brake discs, thereby drying them
more quickly and protecting them against
corrosion.
Limited braking performance on salt-
treated roads If you drive on salted roads, a layer of salt
residue may form on the brake discs and
brake pads. This can result in a significantly
longer braking distance.
R In order to prevent any salt build-up, apply
the brakes occasionally while paying
attention to the traffic conditions.
R Carefully depress the brake pedal and the
beginning and end of a journey.
R Maintain a greater distance to the vehicle
ahead.
Servicing the brakes !
If the red brake warning lamp lights up in
the instrument cluster and you hear a
warning tone while the engine is running,
the brake fluid level may be too low.
Observe additional warning messages in
the multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked
immediately. This work should be carried
out at a qualified specialist workshop. 196

Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane.
Activating DISTRONIC PLUS at traffic lights
with crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
DISTRONIC PLUS with Steering Assist General notes
DISTRONIC PLUS Steering Assist helps you
to drive in the middle of the lane by means of
moderate steering interventions at speeds of
0 - 125 mph (0 - 200 km/h).
DISTRONIC PLUS Steering Assist monitors
the area in front of your vehicle by means of
camera system 0043at the top of the
windshield.
At speeds of more than 37 mph (60 km/h),
DISTRONIC PLUS Steering Assist focuses on
lane markings that are present.
At speeds of 0 - 37 mph (0 - 60 km/h),
DISTRONIC PLUS Steering Assist focuses on
the vehicle in front, taking into account lane markings, e.g. when following vehicles in a
traffic jam.
DISTRONIC PLUS must be active in order for
the function to be available.
Important safety notes
If you fail to adapt your driving style,
DISTRONIC PLUS Steering Assist can neither
reduce the risk of an accident nor override the
laws of physics. DISTRONIC PLUS Steering
Assist cannot take into account road,
weather or traffic conditions. DISTRONIC
PLUS Steering Assist is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
DISTRONIC PLUS Steering Assist does not
detect road and traffic conditions. If you are
following a vehicle which is driving towards
the edge of the road, your vehicle could come
into contact with the curb or other road
boundaries. In the case of deviations in road
markings, beware of other road users, e.g.
cyclists, that are in the direct vicinity of your
vehicle.
Obstacles such as building site huts on the
lane or projecting out into the lane are not
detected.
An inappropriate steering intervention, e.g.
after intentionally driving over a lane marking,
can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS Steering Assist cannot
continuously keep your vehicle in lane. In
some cases, the steering intervention is not
sufficient to bring the vehicle back to the lane.
In such cases, you must steer the vehicle
yourself to ensure that it does not leave the
lane. 210

The system may be impaired or may not
function if:
R there is poor visibility, e.g. due to
insufficient illumination of the road, or due
to snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
R the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R there are no, several or unclear lane
markings for a lane, e.g. in areas with road
construction work
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are strong shadows cast on the lane
Pay attention also to the important safety
notes for DISTRONIC PLUS (Y page 202).
The steering interventions are carried out
with a limited steering moment. The system
requires the driver to keep his hands on the
steering wheel and to steer himself.
If you do not steer yourself or if take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you
with a visual warning. A steering wheel
symbol appears in the multifunction display.
If you have still not started to steer and have
not taken hold of the steering wheel after five
seconds, a warning tone also sounds to
remind you to take control of the vehicle.
DISTRONIC PLUS Steering Assist is then
switched to passive. DISTRONIC PLUS
remains active. The system is switched to passive and no
longer assists you by performing steering
interventions if:
R
you actively change lane
R you use a turn signal
R take your hands off the steering wheel or
do not steer for a prolonged period of time
i After you have finished changing lanes,
DISTRONIC PLUS Steering Assist is
automatically active once more.
DISTRONIC PLUS Steering Assist does not
provide assistance:
R on very sharp corners
R if no roadside markings or no clear roadside
markings have been detected
R if the vehicle in front is not detected at
speeds below 37 mph (60 km/h)
R in tire run-flat mode

General notes AIRMATIC is an air suspension with variable
damping for improved driving comfort. All-
round level control ensures the best possible
suspension and constant ground clearance,
even with a laden vehicle. When you drive
fast, the vehicle is lowered automatically to
improve driving safety and to reduce fuel
consumption. There is also the option to
manually adjust the vehicle level. AIRMATIC consists of level setting, level control and the
Adaptive Damping System ADS.
