226 OperationDriving instructions
Tires
Tread wear 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 (1.5 mm), at which point
the tire is considered worn and should be
replaced.The tread wear indicator appears as a solid
band across the tread.
Specified tire pressures must be main-
tained. This applies particularly if the tires
are subject to high loads (e.g. high speeds,
heavy loads, high ambient temperatures).
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 selector lever to positionP
(manual transmission: first or reverse
gear).


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards the road curb.


Turn the key to starter switch
position0.


Take the key and lock vehicle when leav-
ing.
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-
ti o n t o an a re a wh ic h i s a s a fe dis ta n c e f ro m
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have it towed to the nearest
Mercedes-Benz Center or tire dealer for re-
pairs.
Warning!
G
Do not allow your tires to wear down too far.
As tread depth approaches
1/16
in
(1.5 mm), the adhesion properties on a wet
road are sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.

233 Operation
At the gas station
At the gas station
The fuel filler flap is located on the
right-hand side of the vehicle towards the
rear. Locking/unlocking the vehicle with
the remote control automatically
locks/unlocks the fuel filler flap.
Remove the key from the starter
switch.

Open the fuel filler flap by pushing at
the point indicated by the arrow.
The fuel filler flap springs open.

Turn the fuel cap to the left and hold on
to it until possible pressure is released.

Take off the cap and set it in the recess
on the fuel filler flap.
To prevent fuel vapors from escaping
into open air, fully insert filler nozzle
unit.

Only fill your tank until the filler nozzle
unit cuts out – do not top up or overfill.

Replace the fuel cap by turning it to the
right.
You will hear when the fuel cap is tight-
ened.

Close the fuel filler flap.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious inju-
ry. Whenever you are around gasoline, avoid
inhaling fumes and skin contact, extinguish
all smoking materials. Never allow sparks,
flame or smoking materials near gasoline! Warning!
G
Flexible Fuel Vehicles (MY 2003
Mercedes-Benz C 320 models, except those
equipped with manual transmission or
4MATIC*) only:
Ethanol fuel (E85) and its vapors are highly
flammable, poisonous and burn easily. Etha-
nol fuel can cause serious injuries if ignited
or if you come into contact with it or inhale
fumes of it. Avoid inhalation of Ethanol
fumes and skin contact with Ethanol. Extin-
guish all open flames before fueling. Never
smoke or create sparks close to Ethanol.
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.

Hood
Opening
1Hood release
Pull lever1 downwards.
The hood is unlocked and handle2 will
extend out of the radiator grill. 2Handle for opening the hood

Pull handle2 to its stop out of radiator
grill.

Pull up on the hood (do not pull up on
the handle) and then release it.
The hood will be automatically held
open at shoulder height by gas-filled
struts.
Warning!
G
Do not pull the release lever while the vehi-
cle is in motion. Otherwise the hood could
be forced open by passing air flow.
!To avoid damage to the windshield wip-
ers or hood, never open the hood if the
wiper arms are folded forward away
from the windshield.
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. If necessary,
call the fire department.

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

Check to make sure that 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.
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when

the vehicle is new


the vehicle is driven frequently at high-
er engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
Checking engine oil level
When checking the oil level the vehicle
must


be parked on level ground


be at normal operating temperature


have been stationary for at least five
minutes with the engine turned off
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
turned manually
Warning!
G
Be careful that you do not close the hood on
anyone.

246 OperationWinter drivingBlock heater (Canada only)
The engine is equipped with a block
heater.
The electrical cable may be installed at
your authorized Mercedes-Benz Center.
Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to ex-
ceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.Please observe the following guidelines
when using snow chains:


Use of snow chains is not permissible
with all wheel/tire combinations.


Chains should only be used on the rear
wheels. Follow the manufacturer's
mounting instructions.


Use only snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Center will be
glad to advise you on this subject.
iWhen driving with snow chains, you
may wish to deactivate the ESP
(page 75) before setting the vehicle
in motion. This will improve the vehi-
cle‘s traction.
!Even on vehicles with all-wheel-drive
use snow chains on rear tires only.
Use of snow chains is not permissible
with tire sizes:

The yellow ABS malfunction
indicator lamp comes on while
driving.
The ABS has detected a malfunction and has
switched off. The BAS and the ESP are also
switched off (see messages in display).
The brake system is still functioning normally
but without the ABS available.

Continue driving with added caution.
Wheels may lock during hard braking
reducing steering capability.

Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS has switched off.

When the voltage is above this value
again, the ABS is operational again.

If necessary, have the generator and
battery checked.

The red SRS indicator lamp lights
up while driving.
There is a malfunction in the restraint sys-
tems. The airbags or emergency tensioning
device (ETDs) could deploy unexpectedly or
fail to activate in an accident.

Drive with added caution to the
nearest authorized Mercedes-Benz
Center.

In the event a malfunction of the SRS is indi-
cated as outlined above, the SRS may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an
accident, which could result in serious or
fatal injury, or it might deploy unexpectedly
