vehicle with a tow rope or tow bar. Observe
the following notes.GWARNING
If the brake system is malfunctioning, you
must use a rigid tow bar to tow the vehicle.
Before towing away, make sure that the
steering can be moved and is not locked.
If there is a malfunction in the power supply
or the vehicle's electrical system, you must
not tow the vehicle.
GWARNING
The following can occur if the vehicle is towed:
R the engine may not start.
R the on-board electronics may fail.
R the battery voltage may drop too much.
In these cases, the rear axle will be locked.
As a result, you might lose control of the
vehicle, cause an accident and injure yourself
and others.
! Use the SmartKey instead of the Start/
Stop button when towing the vehicle.
Start the engine and keep it running. Turn
the SmartKey to position 2 in the ignition.
Set the transmission to N using the E-
SELECT lever. Make sure that you then
leave the SmartKey in position 2.
Check the transmission position in the
instrument cluster.
! Make sure that the electric parking brake
is released. If the electric parking brake is
faulty, visit a qualified specialist workshop.
Mercedes-Benz recommends that you use
an authorized Mercedes-Benz Center for
this purpose.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
be damaged.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! You may only tow the vehicle a maximum
distance of 30 miles (50 km). A towing
speed of 30 mph (50 km/h) must not be
exceeded.
For towing distances over 30 miles
(50 km), the vehicle must loaded onto a
transporter.
! Do not tow with sling-type equipment.
This could damage the vehicle.
! Tow-starting the vehicle is not permitted.
The transmission may otherwise be
damaged.
Also observe the following notes:
R if the engine does not start, try jump-
starting it ( Y page 243). Tow-starting the
vehicle is not permitted.
R if it is not possible to jump-start the vehicle,
have it transported to the nearest qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
R if the transmission has been damaged,
have the vehicle transported to the nearest
qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center.
