Vehicle care
Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are prefera-
ble.
To protect the filter system, switch the
climate control system (
page 216) or
the automatic climate control system*
(
page 230) to air recirculation mode.
If the vehicle is very dirty, prewash it
before running it through the automatic
car wash.When taking the vehicle through an auto-
matic conveyor type car wash, observe the
following instructions.Vehicles with SmartKey:
With the vehicle at a standstill and the
ignition switched on shift the automatic
transmission to neutral positionN.
If engaged, release the parking brake
(
page 59).
Switch off the ignition and leave the
SmartKey in the starter switch.
Vehicles with KEYLESS-GO*:
With the vehicle at a standstill, depress
the brake pedal and keep it pressed.
With the ignition switched on shift the
automatic transmission to park
positionP.

!Do not clean your vehicle in an automatic
touchless car wash which use caustic spray.
Otherwise the caustic spray will damage the

!Make sure that the windshield wiper switch
is set to0 (
page 63). Otherwise, e.g. the rain
sensor could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.

with KEYLESS-GO* in the starter switch, do
not leave children unattended in the vehicle.
It is possible for children to switch on the
ignition which could result in unsupervised

Wiper blades are components that are sub-
ject to wear and tear. Replace 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.
