278 Controls in detail
Driving systems
Basic settings
There are two settings from which to
choose:

Raised level, for driving on rough roads

Highway level, for driving on paved
roads in fair or better conditionThe vehicle’s ride height changes by the
approximate values given in table below
according to the set level:
The vehicle lowers to highspeed level
automatically when

the vehicles speed exceeds
70 mph (112 km/h)

the vehicles speed is between
60 mph (96 km/h) and
70 mph (112 km/h) for longer
than 20 seconds
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
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.
Warning!G
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 roads,
adjusting the vehicle to a lower level may cause
the vehicle underbody to come in contact with
the road and result in damage to the vehicle un-
derbody. Always make sure the vehicle has suffi-
cient 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 the ground, remove the SmartKey
from the starter switch.
!Please also note the information in the
section on towing (
page 513).
iThe activation threshold is defined by the set
suspension tuning (
page 276).
iThe third available level is the highspeed
level that is set automatically.

Preparing the vehicle
Prepare the vehicle as described
(
page 492).
Take the wheel wrench and the vehicle
jack from the vehicle tool kit
(
page 469).
Take the spare wheel from the wheel
well under the cargo compartment
floor (
page 472).Lifting the vehicle
iYou can use the power outlets, except for
the power outlet in the front center console, to
operate the electric air pump even when the
ignition is switched off, e.g. in order to inflate the
collapsible tire (
page 499).
An emergency shut-off feature ensures that the
vehicle’s electrical voltage does not fall below a
minimum level. If the voltage drops to this mini-
mum level, the power outlets are automatically
switched off. This ensures that enough power
remains to start the engine.
Warning!G
When jacking up the vehicle, only use the
jack which has been specifically approved
by Mercedes-Benz for your vehicle.
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. Make
sure the jack arm is fully seated in the jack
take-up bracket.
The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not
suited for performing maintenance work
under the vehicle. To help avoid personal in-
jury, use the jack only to lift the vehicle dur-
ing a wheel change.
Never get beneath the vehicle while it is sup-
ported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.

vehicle.
