Setting the following distance in
Distronic
You can set the specified following dis-
tance for Distronic by varying the time set-
ting between 1.0 and 2.0 seconds. Using
this time setting and the current speed of
your vehicle, Distronic calculates and sets
the required following distance to the pre-
ceding vehicle. The set distance will ap-
pear in the right multifunction display
(page 217).
The distance setting thumbwheel for the
time setting is located on the lower section
of the center console.1Thumbwheel for setting following
distanceIncreasing distance
Increasing the distance setting tells
Distronic to maintain a greater following
distance to the preceding vehicle.
Turn thumbwheel1 towards ¯.
Decreasing distance
Decreasing the distance setting tells
Distronic to maintain a shorter following
distance to the preceding ahead.
Turn thumbwheel1 towards ®.
!
Moving the gear selector lever to positionN
while driving cancels the Distronic. However, the
gear selector lever should not be moved to
positionN while driving except to coast when
the vehicle is in danger of skidding (e.g. on icy
roads).
i
Depressing the accelerator pedal does not
deactivate the Distronic. After brief acceleration
(e.g. for passing), the Distronic will resume the
last speed set.
Warning!
G
It is up to the driver to exercise discretion to
select the appropriate setting given road
conditions, traffic, driver’s preferred driving
style and applicable laws and driving recom-
mendations for safe following distance.

Report the incident to the police.
The police will issue a numbered
incident report.
Pass this number on to the
Mercedes-Benz Response Center along
with your password issued to you when
you subscribed to the service.
The Response Center will then attempt

than 20 seconds before door unlock authoriza-
tion was received by the Response Center, you
must wait 15 minutes before pulling the trunk re-
cessed handle again.

260 OperationDriving instructionsPower assistance
Brakes
Warning!
G
The brake system requires electrical energy
for operation.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. In such a case, the
red brake warning lamp (
page 335) and
warning messages (
page 347) in the in-
strument cluster come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and de-
press the pedal much further to obtain the
expected braking effect. If necessary, apply
full pressure to the brake pedal. Brakes are
only applied to the front wheels. Stopping
distance is increased! If there is a malfunc-
tion in the electro-hydraulic brake system,
we recommend that the vehicle be trans-
ported with all wheels off the ground using
flatbed or appropriate wheel lift/dolly equip-
ment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, see “Towing the vehicle”
(page 421).
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle.
Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking ef-
fect. Maintain a safe distance from vehicles
in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.
263 Operation
Driving instructions
Parking
Tires
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1/16
in (1.6 mm), at which point
the tire is considered worn and should be
replaced.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before
turning off
the engine and leaving the vehicle always:
Keep right foot on brake pedal.
Firmly depress parking brake pedal.
Move the gear selector lever to
positionP.
Slowly release brake pedal.
When parked on an incline, turn front
wheels towards the road curb.
Turn the SmartKey in the starter switch
to position0 and remove the SmartKey
from the starter switch, or press the
start/stop button (vehicles with
KEYLESS-GO*).
Take the SmartKey or the SmartKey with
KEYLESS-GO* and lock vehicle when
leaving.
!
Set the parking brake whenever parking or
leaving the vehicle. In addition, move gear selec-
tor lever to positionP. When parking on hills,
turn front wheels towards the road curb.
Warning!
G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tion to an area which is a safe distance from
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to
the nearest Mercedes-Benz Center or tire
dealer for repairs.

Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
injury. Whenever you are around gasoline,
avoid inhaling fumes and skin contact,
extinguish all smoking materials. Never
allow sparks, flame or smoking materials
near gasoline!
Turn off the engine before refueling.Warning!
G
Overfilling of the fuel tank may create pres-
sure in the system which could cause a gas
discharge. This could cause the gas to spray
back out when removing the fuel pump noz-
zle, which could cause personal injury.
