Towing and tow-starting
Important safety notes
GWarning
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine will not run.
R there is a malfunction in the brake system.
R there is a malfunction in the power supply
or the vehicle's electrical system.
With the engine not running, there is no power
assistance for the brake and steering
systems. You will then need considerably
more force to steer and to brake and the
brake pedal travel will be longer. If necessary,
depress the brake pedal with maximum force.
Before towing away, make sure that the
steering can be moved and is not locked.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum
permissible gross vehicle weight of your
vehicle.
It is better to have the vehicle transported
than to have it towed.
! 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.
! 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.
! Drive slowly and smoothly when towing.
Excessive tractive power could otherwise
damage the vehicles.
! Do not tow with sling-type equipment.
This could damage the vehicle.
! On vehicles with KEYLESS-GO, use the
SmartKey instead of the Start/Stop
button. Turn the SmartKey to position 2 in
the ignition lock and shift the automatic
transmission to N. Then, turn the SmartKey
back to 0 and leave it in the ignition lock.
! Vehicles with automatic transmission
must not be started by tow-starting. This
could otherwise damage the transmission.
! Vehicles with 4MATIC must not be towed
with the front or rear axle raised. This could
otherwise damage the transmission.
The automatic transmission must be in
position N while the vehicle is being towed.
The battery must be connected and charged.
Otherwise:
R you will not be able to turn the SmartKey to
position 2 in the ignition lock.
R you will not be able to shift the automatic
transmission to position N.
Vehicles with automatic transmission:
manually release the selector lever lock in
position P(Y page 144).
i Switch the automatic lock ( Y page 181)
off before towing. Otherwise, you could
lock yourself out of the vehicle when
pushing or towing the vehicle.
Installing/removing the towing eye
Installing the towing eye
XRemove the towing eye from the vehicle
tool kit ( Y page 253).GWarning
The exhaust tail pipe may be hot. You could
burn yourself if you touch the tail pipe. Be
particularly careful when removing the rear
cover.
The mountings for the removable towing eyes
are located in the bumpers. They are at the
front and at the rear, behind the covers.
