The doors and the tailgate lock automati-
cally when the ignition is switched on and
the wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or more.You can open a locked door from the in-

Warning!
G
Monitor the closing procedure carefully to
make sure no one is in danger of being in-
jured. To prevent possible personal injury,
always keep hands and fingers away from
the cargo compartment opening when clos-
ing the tailgate. Be especially careful when
small children are around. To stop the clos-
ing procedure, do one of the following:
Press the tailgate closing switch1.
Press the KEYLESS-GO locking/closing
switch*.
Press the Šbutton on the SmartKey
with KEYLESS-GO*.
Press or pull the remote tailgate switch

Even with the SmartKey with KEYLESS-GO*
removed from the vehicle, the tailgate
closing switch can be operated. Therefore,
do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may
cause an accident and/or serious personal
injury.Warning!
G
Only drive with the tailgate closed as,
among other dangers such as blocked
visibility, exhaust fumes may enter the vehi-
cle interior.
iThe doors unlock automatically after an
accident if the force of the impact ex-
ceeds a preset threshold.
The vehicle automatically locks when
the ignition is switched on and the
wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or

Driving systems
Basic settings
There are two setting from which to
choose:
Raised level, for driving on rough roads
Highway level, for driving on paved
roads in fair or better conditionCompared to the highway level, the vehicle
level changes by
+ 1.97 in (+ 50 mm) in raised level
+/- 0 in (+ 0 mm) in highway level
- 0.78 in (- 20 mm) in highspeed level
The vehicle lowers to highspeed level auto-
matically 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
!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 under-
body. 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 the ground,
remove the SmartKey from the starter
switch.!Please also note the information in the
section on towing (
page 499).
iThe activation threshold is defined by
the set suspension tuning
(page 269).
iThe high-speed level is not available
when towing a trailer.iThe third available level is the
highspeed level that is set automatical-
ly.
iObey local speed limits. Use prudent
driving speeds appropriate to prevail-
ing conditions.

nated in red for approximately
10 seconds during the system
self-check after switching on the igni-
tion (together with the SOS button and
the Information button¡).

360 OperationTires and wheelsStep 6 (if applicable)
If your vehicle will be towing a trailer,
load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this reduces
the available cargo and luggage load
capacity of your vehicle (
page 362).
The following table shows examples on
how to calculate total and cargo load
capacities with varying seating configura-
tions and number and size of occupants.
The following examples use a load limit
of 1 500 lbs. This is for illustration
purposes only. Make sure you are using
the actual load limit for your vehicle stated
on the vehicle’s placard (
page 357).

499 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment. This method is
preferable to other types of towing.When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground only so far as necessary to have
the vehicle moved to a safe location where
the recommended towing methods can be
employed.
!Use flatbed or wheel lift/dolly equip-
ment, with the SmartKey in starter
switch turned to position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts. Use the towing eyes.
Switch off the ESP
® (page 101),
tow-away alarm (
page 107) and the
automatic central locking
(
page 130).
Do not tow-start the vehicle.
!Do not tow with one axle raised. Doing
so could damage the transfer case,
which is not covered by the
Mercedes-Benz Limited Warranty.
All wheels must be on or off the ground.
Observe instructions for towing the ve-
hicles with all wheels on the ground.
!When towing the vehicle with all wheels
on the ground, the automatic transmis-
sion must be in positionN and the
SmartKey must be in starter switch
position2.
When towing the vehicle with all wheels
on the ground, the vehicle may be
towed only for distances up to 30 miles
(50 km) and at a speed not to exceed
30 mph (50 km / h).
If the vehicle is towed with the front
axle raised (observe instructions re-
garding flexible drive shaft), the engine
must be shut off (SmartKey in starter
switch position1). Otherwise, the
4-ETS may become engaged which may
cause loss of towing control.
