is malfunctioning. Parking
G
Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you can-
not steer the vehicle with the key removed.
Never leave children unsupervised in the
vehicle. They could release the parking
brake. This could lead to a serious or fatal
accident. G
Risk of fire
Make sure that the exhaust system does
not under any circumstances come into
contact with easily ignitable material such
as dry grass or petrol. The material could
otherwise ignite and set the vehicle on fire. Parking brake 1

2 Release button
X To apply: pull parking brake 1up firmly.
The 3 warning lamp in the instrument
cluster lights up if the engine is running.
i On steep slopes, turn the front wheels
towards the kerb. X
To release: depress the brake pedal and
keep it depressed.
On vehicles with AUTOTRONIC*, the selec-
tor lever lock is released.
X Press release button 2on parking brake
1 and move the parking brake down to the
stop.
The 3 warning lamp in the instrument
cluster goes out. Switching off the engine
G
Risk of accident
If the engine is not running, there is no
power assistance for the steering and
brakes. Steering and braking will then
require significantly greater effort.
As a result, you might lose control of the
vehicle, cause an accident and injure your-
self and others.
Do not switch off the engine while driving.
Vehicles with manual transmission X
Shift to either first or reverse gear.
X Turn the key to position 0(Y page 62) in
the ignition lock and remove it.
The immobiliser is activated. Controls

Refuelling
170with a higher sulphur content is available
(e.g. 0.035 percent by weight), the engine
oil should be renewed at more frequent
intervals. More information about intervals
for changing the engine oil can be obtained
from any Mercedes-Benz Service Centre.
! Using fuel that does not comply with
EN 590 can increase wear and damage the
engine and the exhaust system.
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not add such fuels to diesel fuel and do
not use any special additives (exception:
flow improvers – see "Low outside temper-
atures").
Damage caused by the use of unapproved
fuels or additives is not covered by the war-
ranty. For further information on "Fuel" see
(Y
page 291).
Low outside temperatures The flow properties of diesel may be inade-
quate at low ambient temperatures.
To prevent operating problems, diesel fuel
with improved cold flow qualities is available
during the winter months. Your vehicle must
be refuelled with this winter diesel at temper-
atures of -5 °C or below.
You can use this winter diesel at tempera-
tures down to about -20 °C without problems.
If only summer diesel fuel or less cold-resist-
ant winter diesel fuel (e.g. in Mediterranean
regions) is available, you should add an
amount of flow improver to the fuel corre-
sponding to the outside temperature.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking the vehicle in a heated
garage. G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel engine. Never mix diesel with petrol. This would damage the fuel system and
engine and could result in a vehicle fire.
Flow improver
The effectiveness of a flow improver is not
guaranteed with every fuel. Observe the infor-
mation provided by the manufacturer when
using a flow improver. Only use flow improv-
ers that have been tested and approved by
Mercedes-Benz. Information about flow
improvers that have been tested and
approved by Mercedes-Benz can be obtained
from any Mercedes-Benz Service Centre. Operation

H
The red brake system
warning lamp comes on
while the engine is run-
ning. G
Risk of accident
There is insufficient brake fluid in
the fluid reservoir. X
Pull over and stop the vehicle safely, paying attention to road and
traffic conditions. Do not continue driving under any circumstan-
ces.
X Consult a qualified specialist workshop immediately.
X Observe the additional messages in the multi-function display
(Y page 202).
Do not top up the brake fluid. This will not rectify the fault. ±
The yellow engine diagnos-
tics warning lamp lights up
while the engine is run-
ning. Vehicles with a diesel engine: the
fuel tank has been run dry. X
Start the engine three to four times after refuelling.
Emergency running mode is cancelled. The vehicle need not be
checked. ±
The yellow engine diagnos-
tics warning lamp lights up
while the engine is run-
ning. There may be a fault, for example
R
in the engine management
R in the ignition system
R in the exhaust system
R in the ignition system (for vehi-
cles with petrol engines)
The emission limit values may be
exceeded and the engine can run
in emergency mode. X
Have the vehicle checked as soon as possible at a qualified spe-
cialist workshop. Practical advice
