Example illustration
When the vehicle has been parked for longer
than 20 minutes, the message Tire
pressures will be displayed after
driving a few minutes appears in the
multifunction display.
The TPMS recognizes new wheels or sensors
automatically after the learn-in phase. As long
as the tire inflation pressure values cannot be
allocated to the individual wheels, the
message Tire Pressure Monitor Active
appears. Despite this message, the tire
inflation pressure values are monitored
already.
iWith a spare wheel mounted, the system
may still indicate the tire inflation pressure
of the removed road wheel for some
minutes. If this happens, keep in mind that
the indicated value where the spare wheel
is mounted does not reflect the actual
spare tire inflation pressure.
iOperating radio transmission equipment
(e.g. wireless headsets, two-way radios) in
or near the vehicle could cause the TPMS
to malfunction.

Tire inflation pressure warnings
If the system detects a significant loss of tire
inflation pressure in one or more than one
tire, a message appears in the multifunction
display. In addition, an acoustic warning
sounds and the low tire pressure telltale in the
instrument cluster comes on.

Automatic car wash
GWarning!
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function or DISTRONIC
PLUS before the vehicle is washed in an
automatic car wash.
You can have your vehicle washed in an
automatic car wash from the start. Brushless
car washes are preferable.
XTo protect the filter system, activate the air
recirculation mode using button g on
the climate control panel.
! Do not clean your vehicle in an automatic
touchless car wash which uses caustic
spray. Caustic spray will damage the paint
or ornamental moldings.
If the vehicle is very dirty, prewash it before
running it through the automatic car wash.
! Make sure the combination switch is set
to wiper setting $. Otherwise, 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.
XWhen taking the vehicle through an
automatic conveyor-type car wash:
Make sure the automatic transmission
remains in neutral position N. Observe
instructions, see “Remaining in neutral
position N” ( Y page 117).
When leaving the automatic car wash, make
sure the mirrors are folded out.
After running the vehicle through an
automatic car wash, wipe any wax off of the
windshield and the wiper blade inserts. This
will prevent smears and reduce wiping noise
which can be caused by residual wax on the
windshield.
Ornamental moldings
XFor regular cleaning and care of ornamental
moldings, use a damp cloth.
! Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings
may have chrome appearance, they could
be made of anodized aluminum that will be
damaged when cleaned with chrome
cleaner. Instead, use a damp cloth to clean
those ornamental moldings.
For very dirty ornamental moldings of
which you are sure are chrome-plated, use
a chrome cleaner. If in doubt whether an
ornamental molding is chrome-plated,
contact an authorized Mercedes-Benz
Center.
Headlamps, brake lamps, tail lamps,
side markers, turn signal lenses
XUse a mild vehicle wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
! Only use window cleaning solutions that
are suitable for plastic lamp lenses.
Window cleaning solutions which are not
suitable may damage the plastic lamp
lenses of the headlamps. Therefore, do not
use abrasives, solvents or cleaners that
contain solvents.

GWarning!
Please do not forget that your primary
responsibility is to drive the vehicle. A driver’s
attention to the road must always be his/her
