Towing the vehicle Tow fittingThe screw-in tow fitting is stored
beneath the cargo area floor. Carry it
with you at all times. This fitting is
designed for installation in the tow
sockets located at the front and rear of
the vehicle, and is intended for towing
on paved road surfaces only.
It should not be used to pull a vehicle
out of deep snow, mud, sand, etc.
Always observe all applicable towing
laws and regulations. Access to tow sockets Front:
Use a screwdriver on the left or right
side (arrows) to press the cover out. 530us128
Rear: Pull the cover off.
Screw the tow fittings in until they
are tight. If you do not, the threads
could be damaged.
Do not tow the vehicle by any compo-
nents of the running gear, or lash them
down in any way. If you do so, the
components could be damaged,
leading to possible accidents.<
Use only a nylon towing strap to tow
the vehicle, since the inherent resil-
ience of this material helps protect both
vehicles from sudden jerking move-
ments. 530de318
Avoid "off-center" towing. Be sure
that the tow rope is pulled tightly
when the towing vehicle begins to
move.<
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-startingIt is not possible to start the engine of a
vehicle equipped with an automatic
transmission by towing or pushing.
For instructions on jump starting refer
to page 164.
Never attempt to use your vehicle to
push another vehicle. If you do so,
damage to the energy-absorbing
bumpers could result.

OverviewControlsMaintenanceRepairsDataIndex
Towing the vehicle Towing a vehicle with automatic
transmission1. Place the selector lever in position N
2. Towing speed:
Max. 45 mph (70 km/h)
3. Towing distance:
Max. 95 miles (150 km)
4. Leave the ignition key at position 1 to
ensure that the brake lamps, turn
signals, horn and windshield wipers
remain operative, and to prevent the
steering lock from engaging
5. Switch on the hazard warning
flashers (comply with country-
specific regulations).
Find some means of identifying the
vehicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed. This will
prevent the steering lock from
engaging. The steering and brakes are
without power assist when the engine is
not running. This means that increased
effort is required for steering and
braking.<
Towing with a commercial tow

4. Towing distance:
Maximum 95 miles (150 km).
Remove the rear driveshaft for
longer towing distances with the
front axle lifted; remove the front drive-
shaft for towing over longer distances
with the rear axle lifted. Failure to
comply with this will result in damage to
the transfer box.<
