When towing the vehicle, please, note the following:
With the automatic central locking activated and the
electronic key in starter switch position 2 (vehicles with
KEYLESS-GO: in “On” position, see page 228), the

To prevent the vehicle door locks from locking,
deactivate the automatic central locking. See

properly installed towing eye bolt. Never attach tow
cable, tow rope or tow rod to vehicle chassis, frame
or suspension parts.

the electronic key could not be turned in the starter
switch if the battery is disconnected or discharged. See

starter switch position 2.If the electronic key is left in the starter switch
position 0 for an extended period of time, it can no

to negligent or incorrect care cannot always be removed
or repaired with the car-care products recommended
here. In such cases it is best to seek aid at your
authorized Mercedes-Benz Center.
The following topics deal with the cleaning and care of
your vehicle and give important “how-to” information as
well as references to Mercedes-Benz approved car-care
products.
Additional information can be found in the booklet titled
“Vehicle Car Guide”.Powe r w as h e r
When using a power washer for cleaning the vehicle
always observe manufacturers’ operating instructions.

KEYLESS-GO-card is in close proximity, approx. 3 ft.
(approx. 1m), the vehicle could be inadvertently locked
or unlocked.
Caution!
Never use a round nozzle to power wash tires. The
intense jet of water can result in damage to the tire.
Always replace a damaged tire.
