iLeaving the engine running and the fuel
filler cap open can cause the yellow fuel
tank reserve warning lamp to flash and the
malfunction indicator lamp ! (USA
only) or ; (Canada only) to illuminate.
For more information, see also “Practical
hints” ( Y page 320).XRemove the SmartKey from the starter
switch.
KEYLESS-GO: Open the driver’s door. This
puts the starter switch in position 0, same
as with the SmartKey removed from the
starter switch. The driver’s door then can
be closed again.XOpening: Press fuel filler flap : at the
point indicated by the arrow.XTurn fuel filler cap ; counterclockwise.XTake off fuel filler cap ;.
!
The fuel filler cap is tethered to the fuel
filler neck. Do not drop the cap. It could
damage the vehicle paint finish.
XSet fuel filler cap ; on fuel filler flap :.XFully insert filler nozzle unit and refuel.XOnly fill your tank until the filler nozzle unit
cuts out – do not top off or overfill .XClosing: Turn fuel filler cap ; clockwise
until it audibly engages.
i Close the fuel filler flap before locking the
vehicle. Otherwise the flap locking pin will
prevent closing the fuel filler flap.
XClose fuel filler flap :.
Low outside temperatures (diesel
engine)
! Do not fill the tank with gasoline. Do not
blend diesel fuel with gasoline or kerosene.
The fuel system and engine will otherwise
be damaged, which is not covered by the
Mercedes-Benz Limited Warranty.
To prevent malfunctions, diesel fuel with
improved cold flow characteristics is offered
in the winter months. Check with your fuel
retailer.
Check regularly and before a long trip
For information on quantities and
requirements of operating agents, see “Fuels,
coolants, lubricants, etc.” ( Y page 368).
Check the following:
R Engine oil level ( Y page 230)
R Tire inflation pressure ( Y page 237)
R Coolant level ( Y page 231)
R Vehicle lighting ( Y page 328)
R Washer system and headlamp cleaning

Engine compartment
Hood
GWarning!
Do not pull the release lever while the vehicle
is in motion. Otherwise the hood could be
forced open by passing air flow.
This could cause the hood to come loose and
injure you and/or others.
Opening
GWarning!
Do not open the hood when the engine is
overheated. You could be seriously injured.
Observe the coolant temperature display to
determine whether the engine may be
overheated. If you see flames or smoke
coming from the engine compartment, move
away from the vehicle. Wait until the engine
has cooled. If necessary, call the fire
department.

For more information on engine oil, see
“Fuels, coolants, lubricants etc.”
(Y page 368).
For information on messages in the
multifunction display concerning engine oil,
see the “Practical hints” section
(Y page 308).
Adding engine oil
! Only use approved engine oils and oil
filters required for vehicles with
Maintenance System. For a listing of
approved engine oils and oil filters, contact
an authorized Mercedes-Benz Center or
visit www.mbusa.com (USA only).
The following will result in engine or
emission control system damage not
covered by the Mercedes-Benz Limited
Warranty:
RUsing engine oils and oil filters of
specification other than those expressly
required for the Maintenance System.
RChanging of oil and oil filter at change
intervals longer than those called for by
the Maintenance System.
RUsing any oil additives.
Example illustration: GL 450 (GL 350 BlueTEC,GL 550 similar)
XUnscrew filler cap : from filler neck.XAdd engine oil as required. Be careful not
to overfill with oil.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.
! Excess oil must be siphoned or drained
off. It could cause damage to the engine
and emission control system not covered
by the Mercedes-Benz Limited Warranty.
XScrew filler cap : back on filler neck.
For more information on engine oil, see the
“Technical data” section (Y page 368) and
(Y page 370).
Transmission fluid level
The transmission fluid level does not need to
be checked. If you notice transmission fluid
loss or gearshifting malfunctions, have an
authorized Mercedes-Benz Center check the
transmission.
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, and the
coolant temperature must be below 158‡
(70†).
GWarning!
In order to avoid any potentially serious burns:
RUse 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 display indicates
that the coolant is overheated.
RDo not remove the cap on the coolant
expansion tank if the coolant temperature
is above 158‡ (70†). Allow the engine to
cool down before removing the cap. The
coolant expansion tank contains hot fluid
and is under pressure.

Checking tire inflation pressure
Safety notesGWarning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
Check the tire inflation pressure at least once
a month.
Check and adjust the tire inflation pressure
when the tires are cold ( Y page 234).
Checking tire inflation pressure
manually
Follow the steps below to achieve correct tire
inflation pressure:
XRemove the cap from the valve on one tire.XFirmly press a tire gauge onto the valve.XRead the tire inflation pressure on the tire
gauge and check against the
recommended tire inflation pressure on the
Tire and Loading Information placard on the
driver’s door B-pillar ( Y page 242). If
necessary, add air to achieve the
recommended tire inflation pressure.XIf you have overfilled the tire, release tire
inflation pressure by pushing the metalstem of the valve with e.g. a tip of a pen.
Then recheck the tire inflation pressure
with the tire gauge.XInstall the valve cap.XRepeat this procedure for each tire.
Tire pressure loss warning system
(Canada only)
While the vehicle is being driven, the tire
pressure loss warning system monitors the
set tire inflation pressures by evaluating each
wheel’s rotational speed. This allows the
system to detect a significant loss of pressure
in a tire. If a wheel’s rotational speed changes
due to falling tire inflation pressure, you will
see a corresponding warning message in the
multifunction display.
The tire pressure loss warning system may
function in a restricted manner or with a delay
R when snow chains are mounted to the
vehicle
R in the presence of ice and snow
R when you are driving on a loose surface
(e.g. sand or gravel)
R when you are driving in a very sporty
manner (involving rapid acceleration or
high speeds in curves)
GWarning!
When the multifunction display shows the
message Tire Pressure Check Tires , one
or more of your tires are significantly
underinflated. You should stop and check
your tires as soon as possible, and inflate
them to the proper tire inflation pressure as
indicated on the vehicle’s Tire and Loading
Information placard or on the tire inflation
pressure label.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
