might therefore issue steering instructions
too soon. This may lead to a collision. For this
reason, you should avoid using Parking Guid-
ance in such situations. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Use Parking Guidance for parking spaces:
R that are parallel to the directio noftravel
R that are on straight roads, not bends
R that are on the same level as the road, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat kerbs
Parking tips:
R on narrow roads, drive as closely as possi-
ble pastt he parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 168) warning messages during the
parking procedure.
R when transporting a load which protrudes
from your vehicle, you must not use Parking
Guidance.
R never use Parking Guidance with snow
chains or an emergency spare wheel fitted.
R make sure that the tyre pressures are
always correct.T his hasadirec teffect on
the steering instructions.
R the way you rvehicle is positioned in the
parking space after parkin gis dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. In some cases, Parking Guidance
may guide you too far or not far enough into
a parking space. In some cases, it may also lead you across or onto the kerb. If neces-
sary, cancel the parking procedure with
Parking Guidance.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tyres.
Detecting parking spaces :
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Parking Guidance is automatically activated
when you drive forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle. When
driving at speeds below 30 km/h, you will see
parking symbol ;as a status indicator in the
instrument cluster.
When a parking space has been detected, an
arrow towards the right =or the left :also
appears. Parking Guidance only displays
parking spaces on the front-passenger side
as standard. Parking spaces on the driver's
side are displayed as soon as the turn signal
on the driver's side is activated. To park on
the driver's side, you must leave the driver's
side turn signal switched on until you have
engaged reverse gear. Driving systems

Care of the exterior
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle .This could cause an accident. For
this reason, following a car wash, drive with
particular care until the brakes are dry. G
WARNING
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function and DISTRONIC
PLUS before the vehicle is washed in an auto-
matic car wash.
You can wash the vehicle in an automatic car
wash from the very start.
! Lock the vehicle when washing it in an
automatic car wash. The vehicle could oth-
erwise be damaged.
! We recommend automatic car washes
with an adjustable 15
high-pressure pre-
cleaning program. In car washes that use
high water pressures, there is a danger that
a small quantity of water may leak into the
vehicle.
Wash off excess dirt before cleaning the vehi-
cle in an automatic car wash.
! Make sure that the automatic transmis-
sion is in position Nwhen washing your
vehicle in a tow-through car wash. The vehi-
cle could be damaged if the transmission is
in another position.
! Make sure that:
R the side windows and roof are com-
pletely closed.
R the blower for the ventilation/heating is
switched off (OFF button is depressed/
airflow control is turned to position 0).
R the windscreen wiper switch is at posi-
tion 0. The vehicle could otherwise be damaged.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements for each indi-
vidual country.
X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean.
X Use a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
X Thoroughly hose down the vehicle with a
gentle jet of water.
X Do not point the water jet directly towards
the air inlet.
X Use plenty of water and rinse out the
sponge frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agent dry on the
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
High-pressure cleaning equipment G
WARNING
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Always maintain a distance of at least
30 cm between the vehicle and the high-
pressure cleaner nozzle. Information about
