3Holder

Shift the automatic transmission to
park positionP.

Engage the electronic parking brake.

Turn off the engine.

Vehicles with SmartKey: Remove the
SmartKey from the starter switch.
Vehicles with KEYLESS-GO*: Open the
driver’s door (this puts the starter
switch in position0, same as with the
SmartKey removed from the starter
switch). The driver’s door then can be
closed again.

Open the fuel filler flap by pushing at
the point indicated by arrow 1.
The fuel filler flap springs open.

Turn the fuel cap counterclockwise and
hold on to it until possible pressure is
released.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious per-
sonal injury.
Never allow sparks, flame or smoking mate-
rials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid in-
haling fumes and skin or clothing contact,
extinguish all smoking materials.
Direct skin contact with fuels and the inha-
lation of fuel vapors are damaging to your
health.
i
In case that the central locking system does
not release the fuel filler flap, or the opening
mechanism is clamping, notify Roadside
Assistance or an authorized Mercedes-Benz
Center.

551 Operation
At the gas station

Take off the fuel filler cap and set it in
the direction of arrow 2 and place it
into holder 3 located on the inside of
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 off or over-
fill.

Replace the fuel cap by turning it clock-
wise until it audibly engages.

Close the fuel filler flap.
You should hear the latch close shut.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.i
Make sure to close the fuel filler flap before
locking your vehicle as the flap locking pin pre-
vents closing after you have locked the vehicle.
i
Only use premium unleaded gasoline with a
minimum Posted Octane Rating of 91 (average of
both the Research Octane Number (RON) and
the Motor Octane Number (MON):
(96 RON+86 MON)/2.
Information on gasoline quality can normally be
found on the fuel pump. Please contact gas sta-
tion personnel in case labels on the fuel pump
cannot be found.
For more information on gasoline, see “Premium
unleaded gasoline” (
page 737), see “Fuel re-
quirements” (
page 737), and the Factory Ap-
proved Service Products pamphlet (USA only) in
your vehicle literature portfolio, or contact an au-
thorized Mercedes-Benz Center.
i
Leaving the engine running and the fuel cap
open can cause the yellow engine malfunction
indicator lamp ± to illuminate.
For more information, see the “Practical hints”
section (
page 612).

559 Operation
Engine compartment
Coolant level
The engine coolant is a mixture of water
and anticorrosion/antifreeze.
When checking the coolant level,

the vehicle must be parked on level
ground


the coolant temperature must be
below 158°F (70°C)
The coolant expansion tank is located on
the passenger side of the engine compart-
ment.
Example illustration from CL 5501Cap
2Coolant expansion tank

Using a rag, turn cap1 slowly approx-
imately one half turn counterclockwise
to release any excess pressure.

Continue turning the cap counterclock-
wise and remove it.
The coolant level is correct if the level


for cold coolant: reaches the white
marking (plastic bridge) inside the cool-
ant expansion tank


for warm coolant: is approximately
0.6 in (1.5 cm) higher

Add coolant as required.

Replace and tighten cap1.
For more information on coolant, see the
“Technical data” section (
page 738).
Warning!
G
In order to avoid potentially serious burns:

Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature gauge indi-
cates that the coolant is overheated.


Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid and
is under pressure.


Using a rag, slowly open the cap approx-
imately
1/2 turn to relieve excess pres-
sure. If opened immediately, scalding
hot fluid and steam will be blown out un-
der pressure.


Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene gly-
col which may burn if it comes into con-
tact with hot engine parts.

682 Practical hintsWhere will I find ...?Vehicle jack
Storage position
Remove vehicle jack from its
compartment.

Turn crank handle in direction of arrow
as far as it will go.
Operational position
Turn crank handle clockwise.
Before storing the vehicle jack in its
compartment:


It should be fully collapsed.


The handle must be folded in (storage
position).
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly engage the electronic parking brake
and block wheels before raising vehicle with
jack.
Do not disengage electronic parking brake
while the vehicle is raised. Be certain that
the jack is always vertical (plumb line) when
in use, especially on hills. Always try to use
the jack on level surface. Make sure the jack
arm is fully seated in the jack take-up brack-
et. Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
