Important safety notes
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applying greater force
to the brake pedal. The first 1,000 miles (1,500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R You should therefore drive at varying
vehicle and engine speeds for the first
1,000 miles (1,500 km).
R Avoid heavy loads, e.g. driving at full
throttle, during this period.
R Change gear in good time, before the
tachometer needle is Ôof the way to the
red area of the tachometer.
R Do not manually shift to a lower gear to
brake the vehicle.
R If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown). R
Only select shift ranges 3,2or 1when
driving slowly, e.g. in mountainous terrain.
R Ideally, for the first 1,000m iles (1,500 km)
drive in program E.
i You should also observe these notes on
running in if the engine or parts of the drive
train on your vehicle have been replaced.
i Always observe the respective speed
limits. Driving

Drinking an
ddriving G
WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affec tyour reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident are 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
taking drugs.
Exhaust check G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, all work on the engine must be carried
out by qualified and authorized Mercedes-
Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benz service requirements. Details
can be found in the Maintenance Booklet. Engine oil
! Vehicles with adiesel particle filter: if
the vehicle is predominantly used to travel
short distances, this can lead to
malfunctions in the automatic cleaning of the diesel particle filter. This can result in
fuel collecting in the engine oil and causing
engine failure. Therefore, if you frequently
drive short distances, make sure to drive
on highways or country roads for 20
minutes at least every 310 miles (500km).
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-Benzw arranty.
Do no tdepress the brake pedal continuously
while the vehicle is in motion, e.g. never
cause the brakes to rub by applying constant
slight pedal pressure. This results in
excessive and premature wear to the brake
pads.
Heavy and light loads G
WARNING

Driving systems
Cruise control
Important safety notes G
WARNING
The cruise control is a convenience system
designed to assist the driver during vehicle
operation .The driver is and must always
remain responsible for the vehicle's speed
and for safe brake operation.
Only use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
R The use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
R The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
R Deactivate the cruise control when driving
in fog.
The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. G
WARNING
When cruise control brakes, the brake pedal
is pulled back (i.e. operated automatically).
The area around the pedal must not be
blocked by obstacles:
R Do not place any objectsint he footwell.
R Ensure that floormats and carpets are fixed
securely. In particular, do not place several
floormats on top of one another.
R Do not place your foot under the brake
pedal, as it could become trapped.
Non-compliance could lead you to cause an
accident in which you and/or others could be
seriously injured. General notes Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range
1,2or 3in good time. By
doing so, you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).

control of the vehicle.
High-frequency sources, such as toll stations,
velocity measurement systems, etc. may
cause DISTRONIC to malfunction.
G
WARNING
The DISTRONIC cannot take road and traffic
conditions into account. Only use the
DISTRONIC if the road, weather and traffic
conditions make it advisable to travel at a
constant speed. G
WARNING
Use of the DISTRONIC can be dangerous on
slippery roads.R apid changes in tire traction
can result in wheel spin and loss of control.
The DISTRONIC does not function in adverse
sigh tand distance conditions. Do not use the
DISTRONIC during conditions of fog, heavy
rain, snow or sleet. G
WARNING
The DISTRONIC cannot take weather
conditions into account. Switch off the
DISTRONIC or do not switch it on if:
R roads are slippery or covered with snow or
ice .The wheels could lose traction while
braking or accelerating, and the vehicle
could skid.
R the DISTRONIC system sensor cover is dirty
or visibility is diminished due to snow, rain
or fog, for example. The distance control
system functionality could be impaired.
Always pay attention to surrounding traffic
conditions even while the DISTRONIC is
switched on. Otherwise, you may not be able
to recognize dangerous situations until it is
too late. This could cause an accident in which
you and/or others could be injured. G
WARNING
The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. G
WARNING
Close attention to road and traffic conditions
is imperative at all times, regardless of
whether or not the DISTRONIC is activated.
Use of the DISTRONIC can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a
constant speed.
The DISTRONIC will not react to stationary
objects in the roadway (e.g. a stopped vehicle
in a traffic jam or a disabled vehicle). The
DISTRONIC will also not respond to oncoming
vehicles.
Switch off the DISTRONIC
R when changing from the left to the right
lane if vehicles are moving more slowly in
the left lane
R when entering a turn lane or highway off
ramp
R in complex driving situations, such as in
highway construction zones
In these situations, the DISTRONIC will
continue to maintain the set speed unless
deactivated.
The DISTRONIC is designed and intended only
to maintain a set speed and keep a set
distance from moving objects in front of it.

is opened and will continue after the door is
closed again.
! When driving on extremely rough terrain,
selec tahigh vehicle level in good time.
Make sure there is always sufficient ground
clearance. You will otherwise damage the
vehicle.
! When you raise the vehicle in such a way
that not all wheels have contact with the
ground, remove the SmartKey from the
ignition lock.
General notes
Level control adapts the vehicle level
automatically to the current operating and
driving situation. This results in reduced fuel
consumption and improved handling.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle
to adjust to the new level as quickly as
possible.
The vehicle level may change visibly if you
park the vehicle and the outside temperature
changes. If the temperature drops, the
vehicle level is lower; with an increase in
temperature, the vehicle level rises.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load
discrepancies while still parked. However, for
significant level changes, such as after the
vehicle has been stationary for a long period,
the engine must be on. For safety reasons,
the vehicle is only lowered when the doors are
closed. Lowering is interrupted if a door is
opened, and it continues once the door has
been closed.
Basic settings
Select raised level for very poor road
conditions or highway level for normal road
conditions. The vehicle is automatically lowered to high-
speed level when you:
R
drive faster than 70 mph (112 km/h)
R drive between 60 mph (96 km/h) and
70 mph (112 km/h) for approximately
20 seconds
The individual vehicle levels differ from
highway level as follows:
R raised level: +1.97 in (+50 mm)
R highway level: +/–0 in (+/–0 mm)
R high-speed level: –0.47 in (–12 mm)
i The high-speed level is not available if you
are towing a trailer. Observe the notes on
driving with a trailer (Y page 193).
i Observe the speed limitations. Drive
carefully at an appropriate speed.

Important safety notes G
WARNING
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some
vehicles and is no substitute for attentive
driving.
Blind Spot Assist cannot detect road and
traffic conditions. It may fail to detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident
and injure yourself and others.
