82 Safety and SecurityDriving safety systemsFour wheel electronic traction system (4MATIC) with the ESP
Models with all-wheel-drive only.
The 4MATIC improves vehicle’s ability to
use available traction, e.g. during winter
operation in mountains under snowy
conditions, by applying power to all four
wheels.
Warning!
G
If you see the ESP warning lampv flash-
ing in the speedometer, proceed as follows:
While driving off, apply as little throttle
as possible
While driving, ease up on the accelera-
tor
Adapt your speed and driving style to
the prevailing road conditions
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.!Do not tow with one axle raised.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.
!Performance testing must only be con-
ducted on a two-axle dynamometer.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.!Because of the ESP’s automatic opera-
tion, the engine and ignition must be
shut off (SmartKey in starter switch
position0 or1 or KEYLESS-GO
start/stop button* in position0 or1)
when the parking brake is being tested
on a brake test dynamometer.
Active braking action through ESP may
otherwise seriously damage the front
or rear axle brake system.
Operational tests with the engine
running can only be conducted on a
two-axle dynamometer.

100 Controls in detailLocking and unlocking
Pull remote trunk lid switch1 until the
trunk begins to open.
The trunk lid opens automatically. The
indicator lamp in the switch comes on
and remains lit until the trunk is closed.The trunk can also be opened using the
SmartKey (
page 90) or from its inside in
an emergency, see “Trunk lid emergency
release” (
page 104).
Limiting opening height of trunk lid
The trunk lid opening height can be limited
when transporting goods on a roof rack
(e.g. presence of an MB sport luggage con-
tainer). When activated, the trunk lid opens
to approximately the height of the roof
edge.
You can activate the limiting opening
height of trunk lid using the control system
(
page 150). Closing from the inside
Press the remote trunk lid switch
(page 99) until the indicator lamp in
the switch goes out and the trunk lid is
closed.
To interrupt the closing procedure:
Release the remote trunk lid switch.
If the trunk lid comes into contact with an
object while closing (e.g. luggage that has
been piled too high), the closing procedure
is stopped and the trunk re-opens slightly.
!The trunk lid swings open upwards au-
tomatically. Always make sure there is
sufficient overhead clearance. To stop
the opening procedure, press or pull
the remote trunk lid switch.iIf the trunk lid does not open, it is still
locked separately (if applicable)
(page 105).
If the vehicle was previously centrally
locked, the trunk lid will lock automati-
cally when closed (
page 99). The
turn signals will flash three times to
confirm locking.
Warning!
G
Maintain sight of trunk area while operating
the door mounted switch. Monitor the clos-
ing procedure carefully to ensure that no
one is in danger of being injured.
To interrupt the closing procedure, release
the door mounted remote trunk lid switch.

Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery

defroster is automatically deactivated af-
ter approximately 6 to 17 minutes of oper-
ation depending on the outside
temperature.

Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.!If the rear window defroster switches
off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.

Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:
Keep tires at the recommended infla-
tion pressures.
Remove unnecessary loads.
Remove roof rack when not in use.
Allow engine to warm up under low
load use.
Avoid frequent acceleration and decel-
eration.
Have all maintenance work performed
at the intervals specified in the Service
Booklet and as required by the FSS.
Contact your authorized
Mercedes-Benz Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
Drinking and driving
