Warning!G
Make sure

the seats are properly locked

the seat backrests are in an upright
position and are properly locked
An outboard second-row seat is properly
locked only when lock status indicator 1 is
in hinged position and red marking 2 is
barely visible, see “Lock status indicators
(outboard second-row seats)”
(
page 298).
If a seat and seat backrest are not properly
locked, the seat could move forward and the
seat backrest could fold. You could slide
under the seat belt during braking, vehicle
maneuvers, or in an accident. If you slide
under it, the belt would apply force at the
abdomen or neck. That could cause serious
or even fatal injuries.
!When returning the seats to their original
position, it is important to proceed in the
following order:

third-row seats

outboard second-row seats

second-row middle seat*
Otherwise, you could damage the seats.
!Do not fold up seat cushion 7 before fold-
ing seat backrest 3, see “Folding third-row
seats” (
page 296), as this could damage the
upholstery.

513 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.If circumstances do not permit the recom-
mended 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 recom-
mended towing methods can be employed.
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).
!Do not tow-start the vehicle.
!Use flatbed or wheel lift/dolly equipment,
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 104) and the
automatic central locking (
page 126).
!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 vehicles with all
wheels on the ground.
Warning!G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if

the engine will not run

there is a malfunction in the brake
system

there is a malfunction in the power
supply or in the vehicle’s electrical
system
as that will be necessary to adequately
control the vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the automatic trans-
mission is in neutral positionN.
