and warning messages are simply a remind-
er with respect to the operation of certain
systems and do not replace the owner’s
and/or driver’s responsibility to maintain
the vehicle’s operating safety by having all
required maintenance and safety checks
performed on the vehicle and by bringing
the vehicle to an authorized Mercedes-Benz
Center to address the malfunction and
warning messages (

Switching radar sensors* on/off
If your vehicle is equipped with DISTRONIC
Plus*, BAS Plus*, or Park Assist* it is
equipped with a radar sensor system
which you can switch on and off.
When travelling in Canada in a vehicle not
registered in Canada, you must switch off
the radar sensor system. Canadian law
does not permit the use of the radar sensor
system for vehicles from outside of Cana-
da. When you switch off the radar sensor
system, the following functions are deacti-
vated:

BAS Plus* (

The reflection brightness of the exterior
rear view mirror on the driver’s side and
the interior rear view mirror will respond
automatically to glare when

the ignition is switched on
(page 370)
and


incoming light from headlamps falls on
the sensor in the interior rear view
mirror
The interior rear view mirror will not react if


reverse gearR is engaged


the interior lighting is turned on
Warning!
G
The auto-dimming function does not react if
incoming light is not aimed directly at the
sensors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, if the rear window sun-
shade is in raised position.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic con-
ditions and could cause an accident.
Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
side rear view mirror or glance over your
shoulder before changing lanes.

!
If the windshield wipers leave smears on the
windshield after the car has been driven through
an automatic car wash, then wax or other resi-
due is on the windshield. Shortly after washing
the car in an automatic car wash, clean the wind-
shield with windshield washer fluid
(
page 409).
!
Do not operate the windshield wipers when
the windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/or
damage the wiper blades when wiping occurs on
a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions, al-
ways operate the windshield wipers with wind-
shield washer fluid (
page 409).
!
If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off immediate-
ly.


For safety reasons, stop the vehicle in a safe
location and,

remove SmartKey from starter switch
or


turn off the engine by pressing the
KEYLESS-GO* start/stop button
(page 372) and open the driver’s door
(with the driver’s door open, starter
switch is in position0, same as with
SmartKey removed from starter switch)
before attempting to remove any blockage.


Remove blockage.


Turn the windshield wipers on again.If the windshield wipers fail to function at all in
the combination switch position U or V,


set the combination switch to the next
higher wiper speed


have the windshield wipers checked at the
nearest authorized Mercedes-Benz Center

Windshield wipers
Intermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.

Turn the combination switch to posi-
tion U or V.
The wipers move across the wind-
shield. Afterward, the wiping intervals
are determined by the wetness of the
windshield.
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.
Single wipe
Press the combination switch briefly in
the direction of arrow2 (
page 408)
to the resistance point.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid
Press the combination switch in the di-
rection of arrow2 (
page 408) past
the resistance point.
The windshield wiper operates with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system”
(
page 580).
i
When the windshield wipers are switched on
and you brake the vehicle to a stop, the wipers
operate more slowly.
!
Do not leave windshield wipers on an inter-
mittent setting when the vehicle is taken to an
automatic car wash or during windshield clean-
ing. Wipers will operate in the presence of water
sprayed on the windshield, and windshield wip-
ers may be damaged as a result.
!
If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical effects
may cause the windshield wipers to wipe in an
undesired fashion. This could then damage the
windshield wiper blades or scratch the windows.
You should therefore switch off the windshield
wipers when weather conditions are dry.
i
Intermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or out
of the vehicle from being sprayed.
Intermittent wiping will be continued when


all doors are closed
and


the automatic transmission is set to drive
positionD or reverse gearR
or


the wiper setting is changed using the com-
bination switch
i
To prevent smears on the windshield or
noisy/chattering wiper blades, wipe with wind-
shield washer fluid every now and then even
when it is raining.

Instrument cluster
Tachometer
The red marking on the tachometer de-
notes excessive engine speed.To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
The outside temperature indicator is on
the bottom left-hand side of the instru-
ment cluster (
page 28).
The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. There-
fore, the accuracy of the displayed temper-ature can only be verified by comparison to
a thermometer placed next to the sensor,
not by comparison to external displays
(e.g. bank signs, etc.).
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.
Fuel gauge
The fuel gauge is on the left-hand side of
the instrument cluster (
page 28). Once
the fuel level has fallen below the reserve
mark, the yellow segment indicator for the
fuel reserve comes on.

hicle until the engine has cooled down.!
Excessive coolant temperature triggers a
warning in the multifunction display
(
page 680).
The engine should not be operated with the cool-
ant temperature above 248°F (120°C), i.e. in
the red zone of the coolant temperature gauge.
Doing so may cause serious engine damage
which is not covered by the Mercedes-Benz Lim-
ited Warranty.
i
During severe operating conditions,
e.g. stop-and-go traffic, the coolant temperature
may rise close to 248°F (120°C), i.e. close to
the red zone of the temperature gauge.

Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
