play. Step on the brake immediately to
prevent the vehicle from rolling. DISTRON-
IC Plus is then switched off and the mes-
sage disappears.
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to preset
speed could cause an accident and/or seri-
ous injury you and others.i
Upon switching off the engine, the last
stored speed is deleted.
i
The following message will appear in the
multifunction display for approximately
5 seconds:

(30 km/h) and no preceding vehicle is de-
tected


the ESP
® is in operation or switched off with
the ESP® switch (
page 73)


you set the automatic transmission toP, R,
or N while driving

Driving systems
Parktronic system*
Parktronic is an electronic parking aid with
ultrasonic sensors that helps you while
parking.
It visually and audibly indicates the relative
distance between the vehicle and an ob-
stacle.
Parktronic is automatically activated when
you switch on the ignition, release the
electric parking brake or start the engine
and engage gear D, R or N.The Parktronic system deactivates at
speeds over approximately 11 mph
(18 km/h). At lower speeds the Parktronic
system turns on again.
Parktronic is also switched off when you
engage gear P or secure the vehicle in
place with the electric parking brake and
switch off the engine.
The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors in the front bumper (Only visi-
ble without DISTRONIC Plus*)Warning!
G
Parktronic is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice, see
“Cleaning the Parktronic* system sensors”
(page 538).
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.i
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash, or the
air brakes of trucks) can cause the system to
send erratic indications, and should be taken
into consideration.

Driving systems
Park Assist*
Park Assist is an electronic parking aid
with radar sensors that helps you while
parking.
It visually and audibly indicates the relative
distance between the vehicle and an ob-
stacle.Park Assist is automatically activated
when the engine is running and the trans-
mission is in position D, R or N.
The Park Assist system deactivates at
speeds over approximately 11 mph
(18 km/h). At lower speeds the Parktronic
system turns on again.
Park Assist is also switched off when the
transmission is in position P or switch off
the engine.
While the transmission is in position N,
Park Assist is switched off if you secure the
vehicle in place with the electric parking
brake.
The Park Assist system monitors the sur-
roundings of your vehicle with four sensors
in the front bumper and two sensors in the
rear bumper.Warning!
G
Park Assist is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.!
Special attention must be paid to objects
with smooth surfaces or low silhouettes (e.g.
trailer couplings, painted posts, elevated cross-
bars or road curbs). Such objects may not be de-
tected by the system and can damage the
vehicle.
!
The operational function of the Park Assist
system can be affected by dirty sensors, espe-
cially at times of snow and ice.
Make sure that the area on the bumpers around
the sensors is free of dirt, ice and/or slush,
otherwise Park Assist may not function properly,
see “Cleaning the Park Assist* system sensors”
(
page 538).
!
High-frequency sources such as toll sta-
tions, speed measuring systems, etc. can cause
the Park Assist system to malfunction. You can
switch off the Park Assist using the Park Assist
button (
page 412) or switch off the radar sen-
sors (
page 256) to prevent possible malfunc-
tion.
i
In certain countries and near radio-astrolog-
ical facilities, you must switch off the radar sen-
sors (page 256).

Loading and storing
Loading and storing
Roof rack*

Flip the covers upward.

Only attach the roof-rack system to the
anchorage points under the covers.
Observe manufacturer’s instructions
for installation.
Loading instructions
The total load weight including vehicle oc-
cupants and luggage/cargo should not ex-
ceed the load limit or vehicle capacity
weight as indicated on the corresponding
placard located on the driver’s door B-pillar
(page 503).
Warning!
G
Only use roof racks approved by
Mercedes-Benz for your vehicle model to
avoid damage to the vehicle.
Follow the manufacturer’s installation
instructions. Otherwise, an improperly
attached roof rack system or its load could
become detached from the vehicle.
Do not exceed the maximum roof load of
220 lb (100 kg).
Take into consideration that when the roof
rack is loaded, the handling characteristics
are different from those when operating the
vehicles without the roof rack loaded.
!
Load the roof rack in such a way that the ve-
hicle cannot be damaged while driving.
Make sure


you can fully raise tilt/sliding sunroof or the
panorama roof with tilt/sliding panel*


you can fully open the trunk
Warning!
G
Always fasten items being carried as secure-
ly as possible using cargo tie-down hooks
and fastening materials appropriate for the
weight and size of the load.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when transporting cargo. Put luggage or car-
go in the trunk if possible.

493 Operation
Engine compartment
Closing
Let the hood drop from a height of ap-
proximately 1 ft. (30 cm).
The hood will lock audibly.

Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.
Warning!
G
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running. Make sure the hood is
properly closed before driving. When closing
the hood, use extreme caution not to catch
hands or fingers.
The radiator fan may continue to run for ap-
proximately 30 seconds or even restart af-
ter the engine has been turned off. Stay
clear of fan blades.Warning!
G
If you see flames or smoke coming from the
engine compartment, or if the coolant tem-
perature gauge indicates that the engine is
overheated, do not open the hood. Move
away from vehicle and do not open the hood
until the engine has cooled down. If neces-
sary, call the fire department.
Warning!
G
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components (ig-
nition coils, spark plug sockets, diagnostic
socket) of the ignition system

with the engine running


while starting the engine


if ignition is “on” and the engine is
cranked manually
Warning!
G
Be careful that you do not close the hood on
anyone.
Make sure that the hood is securely en-
gaged before driving off. Do not continue
driving if the hood can no longer engage af-
ter an accident, for example. The hood could
otherwise come loose while the vehicle is in
motion and endanger you and others.
