Notes on 4MATIC vehicles
! Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission.
Vehicles with 4MATIC may either be towed
away with both axles on the ground or be
loaded up and transported.
If the vehicle's transmission, front, or rear
axle is damaged, have the vehicle transported
on a truck or trailer.
In the event of damage to the electrical
system: if the battery is defective, the
automatic transmission will be locked in
position P. To shift the automatic
transmission to position N, you must provide
power to the vehicle's electrical system in the
same way as when jump-starting
(

page 373).
Have the vehicle transported on a transporter
or trailer.
