Electric parking brake
General notes G
WARNING
If you leave children unsupervised in the vehi- cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there is a malfunction in
the system, it may not be possible to apply the
released parking brake.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it rolling
away.
X Shift the automatic transmission to position
005D.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is a malfunction in the system. Contact a
qualified specialist workshop.
i The electric parking brake performs a func-
tion test at regular intervals while the engine
is switched off. The sounds that can be heard while this is occurring are normal. Applying or releasing manually X

The electric parking brake secures the vehicle
automatically if the HOLD function is activated
when the vehicle is stationary and:
R a system malfunction occurs
R the power supply is insufficient
On steep uphill or downhill gradients or if there
is a malfunction, the transmission may also be
automatically shifted to position 005D.AIRMATIC package
General notes AIRMATIC is an air suspension system with var-
iable damping for improved driving comfort.
Level control ensures the best possible suspen- sion and constant ground clearance, even with a laden vehicle. When you drive fast, the vehicle islowered automatically to improve driving safety
and to reduce fuel consumption. There is also
the option to manually adjust the vehicle level.
AIRMATIC consists of:
R level settings
R level control and
R ADS or ADS PLUS (Adaptive Damping Sys-
tem)
All vehicles (except Mercedes-AMG vehi-
cles): your vehicle may also be equipped with
the ACTIVE CURVE SYSTEM (Y page 186).
Mercedes-AMG vehicles: your vehicle is equip-
ped with the ACTIVE CURVE SYSTEM
(Y page 186).
Observe the notes on driving with a trailer
(Y page 222).
The vehicle level can be set using the DYNAMIC
SELECT controller (Y page 147) or the level but-
ton (Y page 187). The setting always corre-
sponds to the last selected function.
Important safety notes G
WARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury. Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load discrep-
ancies while still parked. However, for signifi-
cant 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. Low-
ering is interrupted if a door is opened, and it
continues once the door has been closed.
ADS and ADS PLUS (Adaptive Damping
System) General notes
The Adaptive Damping System automatically
controls the calibration of the dampers. The
damping characteristics adapt to the current
operating and driving situation.
The damping is tuned individually to each wheel
and depends on:
R your driving style, e.g. sporty
R the road surface conditions
R the drive program selected
R the vehicle level setting
Selecting Comfort mode In the
Comfort drive program, the driving char-
acteristics of your vehicle are more comforta-
ble. Therefore, select this mode if you favor a
more comfortable driving style. Also select the
Comfort drive program when driving fast on
straight roads, e.g. on straight stretches of high-
way. Driving systems

Driving systemsDriving and parking

Most U.S. states and all Canadian provinces
require by law:
R Safety chains between the towing vehicle and
the trailer. The chains should be cross-woundunder the trailer drawbar. They must be fas-
tened to the vehicle's trailer coupling, not to
the bumper or the axle.
Leave enough play in the chains to make tight
cornering possible.
R A separate brake system for certain types of
trailer.
R Safety switch for braked trailers. Check the
specific legal requirements applicable to your
state.
If the trailer becomes detached from the tow-
ing vehicle, the safety feature triggers the
trailer brakes. Towing a trailer
There are numerous legal requirements con-
cerning the towing of a trailer, e.g. speed restric-
tions. Make sure that your car/trailer combina- tion complies with the local regulations:
R in your place of residence
R in the location to which you are driving
The police and local authorities can provide reli-
able information.
Observe the following when towing a trailer:
R To gain driving experience and to become
accustomed to the new handling characteris-
tics, you should practice the following in a
traffic-free location:
- cornering
- stopping
- backing up
R Before driving, check:
- trailer tow hitch
- safety switch for braked trailers
- safety chains
- electrical connections
- lights
- wheels
R Adjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
R If the trailer has electronically controlled
brakes, pull away carefully. Brake manually using the brake controller and check whether
the brakes function correctly.
R Secure any objects on the trailer to prevent
the cargo from slipping when the vehicle is in
motion.
R When you couple up a trailer, check at regular
intervals that the load is firmly secured. If the trailer is equipped with trailer lights and
brakes, check the trailer to ensure that these
are working.
R Bear in mind that the handling will be less
stable when towing a trailer than when driving
without one. Avoid sudden steering move-
ments.
R The vehicle/trailer combination is heavier,
accelerates more slowly, has a decreased
gradient climbing capability and a longer
braking distance.
It is more susceptible to side winds and
requires more careful steering.
R If possible, do not brake suddenly, but instead
depress the brake pedal moderately at first sothat the trailer can activate its brakes. Then
increase the pressure on the brake pedal.
R If the automatic transmission repeatedly
shifts between gears on uphill or downhill gra-
dients, shift to a lower gear using the left-hand
steering wheel paddle shifter.
A lower gear and lower speed reduce the risk of engine failure.
R When driving downhill, shift to a lower gear to
utilize the engine's braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if instal- led, the trailer brakes.
R If the coolant temperature increases dramat-
ically while the air-conditioning system is
switched on, switch off the air-conditioning
system.
Coolant heat can also be dissipated by open-
ing the windows and switching the ventilation blower and the interior temperature to the
highest level.
R When overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of the vehicle/trailer com-
bination, you require additional road space in
relation to the vehicle you are overtaking
before you can change back to the original
lane. Towing a trailer
