Distronic
Safety notes
When activated, the Distronic adaptive cruise
control increases the driving convenience
afforded by the cruise control while traveling
on expressways and other major roadways.
R If the Distronic distance sensor detects a
slower moving vehicle directly ahead, your
vehicle speed will be reduced so that you
follow that vehicle at your preset following
distance.
R If there is no vehicle directly ahead of you,
the Distronic will function in the same way
as standard cruise control ( Y page 144).GWarning!
The Distronic requires familiarity with its
operational characteristics. We strongly
recommend that you review the following
information carefully before operating the
system.
GWarning!
When the Distronic is braking, the brake pedal
is retracted (i.e. depressed automatically).
The pedals’ range of motion must not be
impeded by any obstacles:
R Do not place any objects in the footwell.
R Make sure that the floormats and carpets
are securely in place.
R Do not rest your foot underneath the brake
pedal, as it could otherwise be trapped.
You could otherwise cause an accident and
injure yourself and/or others.
GWarning!
The Distronic is a convenience system. Its
speed adjustment reduction capability is
intended to make cruise control more
effective and usable when traffic speeds vary.
It is not however, intended to, nor does it,
replace the need for extreme care.
The responsibility for the vehicle’s speed,
distance to the preceding vehicle and, most
importantly, brake operation to ensure a safe
stopping distance, always remains with the
driver.
The Distronic cannot take street and traffic
conditions into account. Complex driving
situations are not always fully recognized by
the Distronic. This could result in wrong or
missing distance warnings.

Activating Distronic
You can activate the Distronic when the
vehicle speed is between 20 mph (30 km/h)
and 110 mph (180 km/h).
When the Distronic is activated, one or two
cruise control speed segments around the set
speed in the speedometer dial are
illuminated. The multifunction display will
show a message such as
DISTRONIC 55 MPH
(Canada: DISTRONIC 90 km/h).
After approximately 5 seconds the currently
set speed appears in the status indicator of
the multifunction display:
RUSA only: e.g. DTR 55 Miles
RCanada only: e.g. DTR 90 km/h
If the Distronic is not activated after the
cruise control lever is pulled in direction of
arrow ? (Y page 150), you will see the
message DISTRONIC Off in the
multifunction display.
In the following cases you cannot activate the
Distronic:
Rup to 2 minutes after starting the engine
Rwhen you brake
Rwhen you have engaged the parking brake
Rwhen the automatic transmission is in park
position P, reverse gear R, or neutral
position N
Rwhen the ESP® is switched off or has
switched off due to a malfunction

The DSR is an aid for driving downhill. The
DSR regulates your vehicle’s speed when
driving downhill to the value set in the control
system (Y page 141). The steeper the
downhill gradient is, the greater the brake
application. On flat road surfaces, the DSR
brakes only slightly or not at all.
GWarning!
The Downhill Speed Regulation (DSR) is a
convenience system designed to assist the
driver during vehicle operation. The system
must be set to be appropriate for the
topographical and weather conditions
encountered which can change quickly. The
driver is and must remain at all times
responsible for the vehicle speed and for safe
brake operation.
Depending on the programmed speed, actual
vehicle speed and gradient, switching on the
DSR while driving can cause the vehicle to
slow down rapidly and you may hear a sound
which is caused by the activation of the
vehicle’s brake system through the DSR.
Sudden and unexpected deceleration can
result in loss of vehicle control, causing an
accident and/or serious personal injury to
you and others. Do not switch on the DSR in
a circumstance where rapid deceleration
could result in a loss of vehicle control.
The DSR regulates the vehicle’s speed in
automatic transmission positions D, or R.
iIn addition, make use of the engine’s
braking effect by shifting the automatic
transmission into a lower gear.
You can drive slower or faster than the set
speed at any time by braking the vehicle or
depressing the accelerator pedal.
iWhenever the DSR is switched on, the
DSR will use the programmed default
speed to regulate the vehicle’s speed. The
default speed programmed at the factory is
4 mph (Canada: 6 km/h). The default speed
can be reprogrammed using the control
system (Y page 141). The next time the
DSR is switched on, the DSR will use the
newly programmed default speed to
regulate the vehicle’s speed.
Once the DSR is switched on, you can
adjust the set speed using the cruise
control lever (Y page 145). Keep in mind
that adjusting the set speed using the
cruise control lever with the DSR switched
on will not change the programmed default
speed. If the DSR is switched off and then
switched on again, the DSR will use the
programmed default speed.
Depending on the road surface and level of
downhill grade, the DSR may not be able to
maintain the set speed. To maintain the set
speed, apply the brakes if necessary.

Off-road driving program (Vehicles
without enhanced off-road package)
The off-road driving program is designed to
assist the driver when driving off-road in
terrain and crossing water. The off-road
driving program adjusts the engine power and
shifting of the automatic transmission to be
more suitable for the off-road use of the
vehicle. In addition, the ABS, ESP®, and 4-ETS
designed for off-road use are automatically
activated.
In the following situations you should switch
to the off-road driving program:

The system lets you select the chassis and

Adaptive Damping System (ADS)
(Y page 159) and the vehicle level control
(Y page 159).
Adaptive Damping System (ADS)
The Adaptive Damping System (ADS) is
controlled electronically and operates
continuously. It adjusts the damping
characteristics to the current operating and
driving conditions. The damping is adjusted
individually for each wheel. Driving safety and
tire comfort are increased.
The fine tuning of the damping is dependent
on:
Ryour driving style
Rroad surface conditions
Ryour personal settings

Changes to the vehicle level should be made
while the vehicle is moving. The vehicle will
then reach the set level as fast as possible.
When you park the vehicle and the ambient
temperature changes, the vehicle level may
change visibly. When the temperature drops,
the vehicle lowers. When the temperature
rises, the vehicle raises.
The vehicle automatically regulates its ride
height based on the set vehicle height and the
current speed:
RAs your driving speed increases, the vehicle
is lowered by increments until it reaches
highspeed level.
RVehicles with ADS: If you are driving with
the ADS setting COMF or AUTO, the
vehicle is raised back to highway level as
your driving speed decreases.
RVehicles with ADS: You can select the
highspeed level via the ADS setting
SPORT. In ADS SPORT, the vehicle is
lowered directly to highspeed level as your
driving speed increases.
The vehicle begins adjusting to the set vehicle
level as soon as the doors or tailgate are
unlocked or opened or closed with the vehicle
unlocked.
In order to operate the vehicle level control
switch (Y page 160) or (Y page 162),
however, the engine must be running.
GWarning!
Make sure no one is near the wheel housing
or under the vehicle when you lower the
vehicle while it is standing still. Limbs could
become wedged into or under the vehicle.
For safety reasons, the vehicle can only be
lowered with all doors and the tailgate closed.
Lowering is interrupted if a door or the tailgate
is opened and will continue after the door is
closed again.
GWarning!
Please be aware that by raising the vehicle
level, the center of gravity also rises.
Therefore, always ensure that the vehicle
level is as low as possible. With higher ride
height the ESP® may activate earlier in certain
situations.
Adapt your speed and driving to possible
changed driving behavior of the vehicle after
changing the vehicle level. The ESP® cannot
prevent accidents, including those resulting
from excessive speed. The ESP® cannot
prevent the natural laws of physics from
acting on the vehicle.
! Keep in mind that in rough or uneven
terrain, adjusting the vehicle to a lower
level may cause the vehicle underbody to
come in contact with the ground and result
in damage to the vehicle underbody.
Always make sure the vehicle has sufficient
ground clearance before adjusting it to a
lower level.
! Before jacking up the vehicle with
equipment that lifts one or more of the
wheels completely off of the ground,
remove the SmartKey from the starter
switch.
