Useful features
Remote door unlock
In case you have locked your vehicle unin-
tentionally (e.g. key inside vehicle), and the
reserve key is not handy:
Contact the Mercedes-Benz Response
Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
You will be asked to provide your pass-
word which you provided when you
completed the subscriber agreement.

Then return to your vehicle and pull
outside trunk handle for minimum of
20 seconds until the SOS button is
flashing.
As an alternative, you may unlock the vehi-
cle via Internet using the ID and password
sent to you shortly after the completion of
your acquaintance call.
The Response Center will then unlock your
vehicle with the remote door unlocking
feature.
iThe indicator lamp in the respective
button flashes until the call is conclud-
ed. Calls can only be terminated by a
Response Center or Customer Assis-
tance Center representative, except
Roadside Assistance and Information
calls.iWhen a Tele Aid call has been initiated,
the audio system is muted and the se-
lected mode (radio, tape or CD) paus-
es. The optional cellular phone (if
installed) switches off. If you must use
this phone, the vehicle must be parked.
Disconnect the coiled cord and place
the call.
iThe remote door unlock feature is avail-
able if the relevant cellular phone net-
work is available.
The SOS button will flash to indicate re-
ceipt of the door unlock command.
Once the vehicle is unlocked, a Re-
sponse Center specialist will attempt
to establish voice contact with the ve-
hicle occupants.
If the trunk handle was pulled for more
than 20 seconds before door unlock
authorization was received by the Re-
sponse Center, you must wait
15 minutes before pulling the trunk
handle again.

170 OperationAt the gas station
You will hear when the fuel cap is tight-
ened.

Close the fuel filler flap.
You should hear the latch close shut.

ervoir can be found in the “Operation”
section (

found in the “Operation” section
(page 176).
4Engine oil level
More information on engine oil can be
found in the “Operation” section
(page 172).

Vehicle lighting
Check function and cleanliness. For more
information on replacing light bulbs, refer

Tire inflation pressure
More information on tire inflation pressure
can be found in the “Operation” section
(
page 181).
iLeaving the engine running and the fuel
cap open can cause the
?
lamp to
illuminate.
More information can be found in the
“Practical hints” section (
page 199).

172 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
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.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.

173 Operation
Engine compartment
You can check the engine oil level with
the oil dipstick
Open the hood (
page 171).

Pull out oil dipstick1 (
page 175) and
wipe the tip clean.

Reinsert the oil dipstick into the dip-
stick guide tube as far as it will go.
1Oil dipstick

Pull out the oil dipstick again after
approximately 3 seconds.
The oil level is acceptable when it
leaves a line between the upper and
lower marks of the dipstick.
For adding oil (
page 175).
See “Practical hints” (
page 200) if the
low engine oil level warning lamp in the in-
strument cluster lights up.You can check the engine oil level on the
odometer display (SLK 320 and
SLK 32 AMG only)

Turn the key in the steering lock to
position2.
1Knob

Wait until the symbols
:
and
I

appear in the odometer display indica-
tor.
iFill quantity between upper and lower
dipstick marking level is approximately
2.1 US qt (2.0 l).


174 OperationEngine compartment
Within 1 second press knob1 on the
instrument cluster twice.
One of the following messages will sub-
sequently appear in the indicator:

OK


-1.0 Q
(Canada:
-1.0 L
)


-1.5 Q
(Canada:
-1.5 L
)


-2.0 Q
(Canada:
-2.0 L
)
For adding oil (
page 175).If there is excessive engine oil with the en-
gine at normal operating temperature, a
signal sounds and the following message
will blink in the odometer display:
HI
Have excess oil siphoned.
If theI
symbol flashes in the odometer
display field, a proper oil level check can-
not be performed.

Wait 5 minutes before repeating check
procedure.
Perform the oil level check with the dip-
stick (
page 173) if it cannot be complet-
ed via the odometer display field. In this
case we recommend that you that you
have the system checked at a
Mercedes-Benz Center.See “Practical hints” (
page 200) if the
low engine oil level warning lamp in the in-
strument cluster lights up.
!If the message
-2.0 Q

(Canada:
-2.0 L
) blinks and a signal
sounds, add oil according to amount
displayed.
iIf the
:
and
I
symbols are con-
tinuously illuminated after pressing the
left knob on the instrument cluster
twice, and if there is no change in the
odometer display field or the low en-
gine oil level warning lamp comes on, a
malfunction has occurred to the sys-
tem.
Perform the engine oil level check with
the dipstick (
page 173).
If no oil leaks are noted, drive to the
nearest Mercedes-Benz Center to have
the system checked.

181 Operation
Tires and wheels
Life of tire
The service life of a tire is dependent upon
varying factors including but not limited to:

Driving style


Tire pressure


Distance driven
Direction of rotation
Unidirectional tires offer added advantag-
es, such as better aquaplaning perfor-
mance. To benefit, however, you must
ensure that the tires rotate in the direction
specified.
An arrow on the sidewall indicates the in-
tended direction of tire rotation.Checking tire inflation pressureCorrect the tire pressure only when tires
are cold.
Regularly check your tire pressure at inter-
vals of no more than 14 days.
If the tires are warm, you should only cor-
rect the tire pressure if it is too low for cur-
rent operating conditions.
A table on the fuel filler flap lists the spec-
ified tire inflation pressures for warm and
cold tires as well as for various operating
conditions.
Warning!
G
Tires and spare tire should be replaced after
six years, regardless of the remaining tread.!Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact
with oil, grease and gasoline.
Warning!
G
If the tire pressure repeatedly drops:

Check the tires for punctures from for-
eign objects.


Check to see whether air is leaking from
the valves or from around the rim.
iThe pressures listed for light loads are
minimum values offering high driving
comfort.
Increased inflation pressures listed for
heavier loads may also be used for light
loads. These higher pressures produce
favorable handling characteristics. The
ride of the vehicle, however, will be
somewhat harder. Never exceed the
max. values or inflate tires below the
min. values listed in the fuel filler flap.
