Driving tips
Accelerator position
Your driving style influences the
transmission’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
Press the accelerator past the point of
resistance.
Depending on the engine speed the
transmission shifts into a lower gear.

Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.Stopping
When you stop briefly, e.g. at traffic lights:

Leave the transmission in gear.

Hold the vehicle with the brake.
When you stop for a longer period of time
with the engine idling and/or on a hill:

Engage the electronic parking brake.

Shift into park positionP.
Maneuvering
When you maneuver in tight areas,
e.g. when pulling into a parking space:

Control the vehicle speed by gradually
releasing the brakes.

Accelerate gently.

Never abruptly step on the accelerator.

When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and

With the engine running, the indicator
lamp1 in the exterior mirror lights up
yellow up to a speed of 20 mph
(30 km/h).Once a speed above 20 mph (30 km/h)
has been reached and


Blind Spot Assist detects no vehicle in
its range, the indicator lamp1 goes
out


Blind Spot Assist detects another vehi-
cle in its range, the warning lamp1 on
the corresponding side of the vehicle
turns red.Collision warning
If a vehicle is detected in the Blind Spot As-
sist range and you activate the turn signal,
a two-tone warning will sound and the red
warning lamp1 will flash.

Remain on the lane that you are cur-
rently on until traffic conditions permit
to change.
If the turn signal remains on, the red warn-
ing lamp1 will flash to indicate that vehi-
cles have been detected. No further
audible warnings will sound.
Warning!
G
Blind Spot Assist is not active at speeds be-
low approximately 20 mph (30 km/h). You
will not be alerted to the presence of vehi-
cles in the monitored area at these speeds.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle. Failure to do so could
result in recognizing dangers too late, possi-
bly resulting in an accident and serious inju-
ry to yourself and others.
Warning!

Do not change lanes or make turns, while
the red warning lamp

is flashing. Doing
so could result in an accident and seroius in-
jury to yourself and others.

690 Practical hintsReplacing bulbsNotes on bulb replacement


Only use 12-volt-bulbs of the same
type and with the specified watt rating.


Switch lights off before changing a bulb
to prevent short circuits.


Always use a clean lint-free cloth when
handling bulbs.


Your hands should be dry and free of oil
and grease.


If the newly installed bulb does not
come on, contact an authorized
Mercedes-Benz Center.
Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center:


Bi-Xenon lamps

Front fog lamps


Additional turn signal lamps in the exte-
rior rear view mirrors


Parking and standing lamps

Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:

touch or move it when hot


drop the bulb


scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.

Do not replace the LEDs yourself. You could
otherwise damage the LEDs or parts of the vehi-
cle. Only have the LEDs replaced by an autho-
rized Mercedes-Benz Center.
