Selecting Distronic X
Check whether LIM indicator lamp 2is off.
If it is off, Distronic is already selected.
If it is not, press the cruise control lever in
the direction of arrow 5.
LIM indicator lamp 2in the cruise control
lever goes out. Distronic is selected. Switching on Distronic, storing the cur-
rent speed and maintaining it If Distronic is not activated after the cruise
control lever is pressed, you will see the mes-
sage - - - in the multi-function display.
You cannot activate Distronic in the following
circumstances:
R if you are driving slower than 30 km/h or
faster than 180 km/h
R when braking
R when you have applied the parking brake
R if ESP ®
is deactivated
R when the selector lever* is in position P,
R or N
R for two minutes after the engine is started
X Accelerate the vehicle to the desired
speed.
X Briefly press the cruise control lever up
1 or down 4.
X Remove your foot from the accelerator
pedal.
Distronic is activated. The vehicle main-
tains the stored speed until the distance to
the vehicle in front becomes too small. i
If you do not fully release the accelerator
pedal, the DISTRONIC override message
appears in the multi-function display. The
distance to a slower-moving vehicle in front
will then not be adjusted. You will be driving
at the speed you determine by the position
of the accelerator pedal.
Setting a speed X
Press the cruise control lever up 1for a
higher speed or down 4for a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored.
i Deceleration of the vehicle by means of
the cruise control lever is assisted by auto-
matic application of the brakes. On long
downhill gradients, the automatic trans-
mission* shifts down as a further measure. Controls

To store the current speed or a higher
speed
2 LIM indicator lamp
3 To store the current speed or call up the
last stored speed or to make fine adjust-
ments in 1 km/h increments
4 To store the current speed or a lower
speed
5 To switch between cruise control, Dis-
tronic* and variable Speedtronic
6 To deactivate variable Speedtronic
Selecting variable Speedtronic X
Check whether LIM indicator lamp 2is on.
If it is on, variable Speedtronic is already
selected. If it is not, press the cruise control lever in
the direction of arrow
5.
LIM indicator lamp 2in the cruise control
lever lights up. Variable Speedtronic is
selected. G
Risk of accident
If there is a change of drivers, advise the
new driver of the limit speed stored.
Only use Speedtronic if you will not have to
accelerate suddenly to a speed above that
stored as the limit speed. You could other-
wise cause an accident.
You can only exceed the limit speed stored
if you deactivate variable Speedtronic:
R using the cruise control lever.
R by depressing the accelerator pedal
beyond the pressure point (kickdown).
It is not possible to deactivate variable
Speedtronic by braking.
Storing the current speed You can use the cruise control lever to limit
the speed to any speed above 30 km/h while
the engine is running. X
Briefly press the cruise control lever up
1 or down 4.
The current speed is stored. The stored
speed, e.g. LIM km/h, appears in the multi-
function display.
The segments in the speedometer from the
start of the scale up to the stored speed
light up.
Storing the current speed or calling up
the last stored speed G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for
the current driving and traffic situation.
Otherwise, sudden braking could endanger
you or others.
X Briefly pull the cruise control lever towards
you 3. Controls

Risk of injury
Make sure that nobody can become trap-
ped as you close the bonnet. X
Lower the bonnet and let it fall from a
height of approximately 20 cm.
X Check that the bonnet has engaged prop-
erly.
i If the bonnet can be raised slightly, it is
not properly engaged. Open it again and
close it with a little more force. Engine oil
Depending on driving style, the vehicle con-
sumes a maximum of 0.8 l oil per 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. You can only
estimate the oil consumption after you have
driven a considerable distance.
You will find further information about engine
oil in the "Technical data" section
(Y page 385).
Checking the engine oil level To do so:R
the vehicle should be parked on level
ground.
R the engine should be switched off for at
least five minutes if the engine was at nor-
mal operating temperature.
R the engine should be switched off for at
least 30 minutes if the engine was not at
operating temperature (i.e. if you only star-
ted the engine briefly).
Via the on-board computer*
i Only possible on the E 420 CDI. On all
other models a dipstick is used to check
the engine oil level (Y page 224).
X Make sure that the key is in position 2in
the ignition lock (Y page 76).
X Press the jork button to select the
message: Engine oil level Measuring
now
The measurement takes a few seconds. You
will see one of the following messages in the
display:
R Engine oil level OK

the catalytic converter if there is excess oil
in the engine.
If the Switch ignition on to check
engine oil level message appears:
X Turn the key to position 2in the ignition
lock (Y page 76).
You will see the following message if you did
not observe the required waiting time:
Observe waiting period X
Repeat the measurement after about five
minutes if the engine is at normal operating
temperature.
X Repeat the measurement after about
30 minutes if the engine is not at normal
operating temperature (if the engine was
only started briefly).
The following message appears if the engine
is running:
Engine oil level Not when engine on
X Switch off the engine and wait for five
minutes if the engine is at normal operating
temperature, or for about 30 minutes if the
engine is not at normal operating temper-
ature (if the engine was only started
briefly), before measuring.
i If you wish to cancel the measurement,
press the korj button on the multi-
function steering wheel. Using the oil dipstick Illustration: vehicle with a petrol engine (E 350)

X Unscrew cap 1and remove it.
X Top up with the amount of oil required.
! Do not add too much oil. If too much oil
is added and the oil level is above the max-
imum mark on the dipstick, the engine or
catalytic converter could be damaged.
Have excess oil siphoned off.
X Screw cap 1onto the filler neck. H
Environmental note
When topping up the oil, take care not to
spill any. Oil must not be allowed to escape
into the soil or waterways. You would oth-
erwise be damaging the environment. Coolant
G
Risk of injury
The cooling system is pressurised. There-
fore, only unscrew the cap once the engine
has cooled down. The coolant temperature
gauge must display less than 70°C. You
could otherwise be scalded by escaping hot
coolant.
Coolant consists of water and antifreeze/cor-
rosion inhibitor. Only check the coolant level
when the vehicle is on a level surface and the
engine has cooled down. Operation

the washer fluid reservoir. 1
Cover X
Add windscreen washer concentrate to the
washer fluid all year round. G
Risk of fire
Windscreen washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windscreen washer
concentrate is being handled.
Use
R a windscreen washer fluid additive
such as MB Summerwash to prevent
smearing (for temperatures above freez-
ing).
R a windscreen washer fluid additive with
antifreeze properties such as MB Winter-
wash (if there is a risk of frost).
X Mix the windscreen washer fluid in a con-
tainer beforehand. Adapt the mixing ratio
to the outside temperatures.
! Only use windscreen washer fluid which
is suitable for plastic lamp lenses. Unsuit-
able windscreen washer fluid could dam-
age the plastic lamp lenses of the head-
lamps. Operation
