252 Controls in detailDriving systemsDistronic does not act upon adverse sight
and distance conditions. Do not use
Distronic during conditions of fog, heavy
rain, snow or sleet.Warning!
G
Distronic cannot take weather conditions
into account. Switch off Distronic or do not
switch it on if:

roads are slippery or covered with snow
or ice. The wheels could lose traction
while braking or accelerating, and the
vehicle could skid.


the sensor 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 Distronic is switched
on. Otherwise, you may not be able to recog-
nize dangerous situations until it is too late.
This could cause an accident in which you
and others could be injured.
Warning!
G
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.Warning!
G
Close attention to road and traffic condi-
tions is imperative at all times, regardless of
whether or not Distronic is activated.
Use of Distronic can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a
continuous speed.
Distronic will not react to stationary objects
in the roadway (e.g. a stopped vehicle in a
traffic jam or a disabled vehicle). Distronic
will also not respond to oncoming vehicles.
Switch off Distronic:

when changing from the left to the right
lane if vehicles are moving more slowly
in the left lane


when entering a turn lane or highway off
ramp


in complex driving situations, such as in
highway construction zones
In these situations, Distronic will continue to
maintain the set speed unless deactivated.
Distronic is designed and intended only to
maintain a set speed and keep a set dis-
tance from moving objects in front of it.

reduce fuel consumption


improve driving stability by lowering
the center of gravity
The vehicle automatically regulates its ride
height based on the set vehicle height and
the current speed:


As your driving speed increases, the ve-
hicle is lowered by increments until it
reaches high-speed level.


If you are driving with the ADS setting
COMF or AUTO, the vehicle is raised
back to highway level as your driving
speed decreases.


You can select the high-speed level via
the ADS setting SPORT. In ADS Sport,
the vehicle is lowered directly to
high-speed level as your driving speed
increases.The parked vehicle begins adjusting to the
set vehicle level as soon the doors and tail-
gate are


unlocked
or


opened or closed with the vehicle
unlocked
In order to operate the vehicle level control
switch (
page 271), however, the engine
must be running.
i
The setting is stored when you turn off the
engine.
Warning!
G
Make sure that 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 ve-
hicle.
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.

Please be aware that by raising the vehicle
level, the center of gravity also rises. There-
fore, 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 pre-
vent the natural laws of physics from acting
on the vehicle.
!
Keep in mind that in rough or uneven ter-
rain, 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 vehi-
cle underbody. Always make sure the vehicle has
sufficient ground clearance before adjusting it to
a lower level.
!
Before jacking up the vehicle with equip-
ment that lifts one or more of the wheels com-
pletely off of the ground, remove the SmartKey
from the starter switch.
!
Please also note the information in the
section on towing (
page 518).

Warning!
G
Parktronic is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors,
especially at times of snow and ice. See
“Cleaning the Parktronic system sensors”
(page 408).
Interference caused by other ultrasonic
signals (e.g. working jackhammers, car
wash, or the air brakes of trucks) can cause
the system to send erratic indications, and
should be taken into consideration.
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.


282 Controls in detailLoadingLoad distributionThe gross vehicle weight which is the
weight of the vehicle including fuel, tools,
spare wheel, installed accessories, pas-
sengers and luggage/cargo must never
exceed the load limit and Gross Vehicle
Weight Rating (GVWR) for your vehicle as
specified on the placard located on the
driver’s door B-pillar (
page 530). In addi-
tion, the load must be distributed in such a
way so that the weight on each axle never
exceeds the Gross Axle Weight Rating
(GAWR) for the front and rear axle. The
GVWR and GAWR for your vehicle are indi-cated on the certification label which can
be found on the driver’s door B-pillar
(
page 530).
For more information, see “Tire and Load-
ing Information” (
page 369).
The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.
Please pay attention to and comply with
the following instructions when loading the
vehicle and transporting cargo:


Always place items being carried
against front or rear seat backrests,
and fasten them as securely as possi-
ble.


The heaviest portion of the cargo
should always be kept as low as possi-
ble against front or rear seat backrests.For additional safety when transporting
cargo while the rear seats are unoccupied,
fasten the outer seat belts crosswise into
the opposite side buckles.
i
The cargo compartment is the preferred
place to carry objects. The expanded cargo com-
partment (
page 284) should only be used for
items which do not fit in the cargo compartment
alone.
