Warning!

For safety reasons, switch off wipers and

remove SmartKey from starter switch (vehi-

cles with KEYLESS-GO*: Make sure the

vehicle’s on-board electronics have

status

) before replacing a wiper blade.

Otherwise the motor could suddenly turn on

and cause injury.

Warning!

Wiper blades are components that are sub-

ject to wear and tear. Change the wiper

blades twice a year, preferably in the spring

and fall. Otherwise the windows will not be

properly wiped. As a result, you may not be

able to observe surrounding traffic condi-

tions and could cause an accident.

Never open the hood when the wiper arms

are folded forward.

Hold on to the wiper when folding the wiper arm
back. If released, the force of the impact from
the tensioning spring could crack the windshield.

Do not allow the wiper arms to contact the wind-
shield glass without a wiper blade inserted.

Make sure the wiper blades are properly
installed. Improperly installed wiper blades may
cause windshield damage.

For your convenience, we recommend that you
have this work carried out by an authorized
Mercedes-Benz Light Truck Center.

Do not pull on the wiper blade inserts. They

could tear.
