For this reason, you should always switch off
the windshield wipers in dry weather.
Vehicles with a rain sensor: in the ÄorÅ
position, the appropriate wiping frequency is
automatically set according to the intensity of
the rain. In the Åposition, the rain sensor is
more sensitive than in the Äposition, caus-
ing the windshield wiper to wipe more fre-
quently.
If the wiper blades are worn, the windshield will
no longer be wiped properly. This could prevent
you from observing the traffic conditions.

Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
wiper.
!Never open the hood/tailgate if a wiper arm
has been folded away from the windshield/
rear window.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
wiper arm without a wiper blade and it falls
onto the windshield/rear window, the wind-
shield/rear window may be damaged by the
force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.

Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (
Ypage 196).
It is possible to shift the transmission from posi-
tion jto the desired position only if you
depress the brake pedal. Only then can the
parking lock be deactivated.
All vehicles (except Mercedes-AMG vehi-
cles): if you do not depress the brake pedal, the
DIRECT SELECT lever can still be moved but the parking lock remains engaged. Mercedes-AMG vehicles:
if you do not depress
the brake pedal, the selector lever can still be
moved but the parking lock remains engaged.
At transmission fluid temperatures below Ò4 ‡
(Ò20†), you can only shift out of position jinto
another transmission position when the engine
is running.
iUpshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly.
Information on the automatic release of the
electric parking brake (
Ypage 145).
Hill start assist
Hill start assist helps you when pulling away
forward or in reverse on an uphill gradient. It
holds the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and to
depress it before the vehicle begins to roll.
GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
Ryou are pulling away on a level road or on a
downhill gradient.
Rthe transmission is in position i.
Rthe electric parking brake is applied.

Notes on programming the remote con-
trol
Canadian radio frequency laws require a "break"
(or interruption) of the transmission signals
after broadcasting for a few seconds. Therefore,
these signals may not last long enough for the
integrated garage door opener. The signal is not
detected during programming. Comparable withCanadian law, some U.S. garage door openers
also feature a "break".
Proceed as follows:
Rif you live in Canada
Rif you have difficulties programming the
garage door opener (regardless of where youlive) as you follow the programming steps.
XPress and hold one of buttons ;to? on the
integrated garage door opener.
After a short time, indicator lamp :lights up
yellow.
XRelease the button.
Indicator lamp :flashes yellow.
XPress button Bof garage door remote con-
trol Afor two seconds, then release it for two
seconds.
XPress button Bagain for two seconds.
XRepeat this sequence on button Bof remote
control Auntil indicator lamp :lights up
green.
When indicator lamp :lights up green: pro-
gramming is finished.
When indicator lamp :flashes green: pro-
gramming was successful. The ne
xt step is to
synchronize the rolling code.
XRelease button Bof remote control Aof the
garage door drive.
If indicator lamp :lights up red: repeat the
programming process for the corresponding
button on the rear-view mirror. When doing
so, vary the distance between remote control
A and the rear-view mirror.
The required distance between remote con-
trol Aand the integrated garage door opener
depends on the garage door drive system.
Several attempts might be necessary. You
should test every position for at least
25 seconds before trying another position.
Problems when programming
If you are experiencing problems programming
the integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
RCheck the transmitter frequency used by
garage door drive remote control Aand
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remote control Afor the garage door drive.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
RReplace the batteries in garage door remote
control A. This increases the likelihood that
garage door remote control Awill transmit a
strong and precise signal to the integrated
garage door opener.
RWhen programming, hold remote control A
at varying distances and angles from but-
tons ;to? which you are programming. Try
various angles at a distance between 2and
8 inches (5to 20 cm) or at the sa
me angle but
at varying distances.
RIf another remote control Ais available for
the same garage door drive, repeat the same
programming steps with this remote control
A. Before performing these steps, make sure
that new batteries have been installed in
garage door drive remote control A.
RNote that some remote controls only transmit
for a limited amount of time (the indicator
lamp on the remote control goes out). Press
button Bon remote control Aagain before
transmission ends.
RAlign the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
Opening/closing the garage door
After it has been programmed, the integrated
garage door opener performs the function of the
garage door system remote control. Please also
read the operating instructions for the garage
door system.
XTurn the SmartKey to position 2in the ignition
lock (Ypage 124).
XPress button ;,=or? which you have
programmed to operate the garage door.

Engine oil
General notes
Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
600 miles (1,000 km). The oil consumption may
be higher than this when the vehicle is new or if
you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be
in a different location.
When checking the oil level:
Rpark the vehicle on a level surface
Rthe engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature
Rif the engine is not at normal operating tem-
perature, e.g. if the engine was only started
briefly, wait about 30 minutes before carrying
out the measurement
Checking the oil level using the oil dip-
stick
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
