A driver’s attention to the road must always
be his / her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the
hands-free device and only use the tele-
phone when weather, road and traffic condi-
tions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)

Refueling
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.
Turn the engine off
by turning the SmartKey to
position0.
by pressing the KEYLESS-GO*
start/stop button. Open the driv-
er’s door (with the driver’s door
open, starter switch is now in
position0, same as SmartKey re-
moved from starter switch).
Remove the SmartKey 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 off or over-
fill.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
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 can damage 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 Assis-
tance or an authorized Mercedes-Benz Center.
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.
322 OperationAt the gas station
Replace fuel cap by turning it clockwise
until it audibly engages.
Close the fuel filler flap.
Check regularly and before a long trip

Leaving the engine running and the fuel cap
open can cause the yellow fuel tank reserve
warning lamp to flash and the malfunction indi-
cator lamp? (USA only) or the malfunction
indicator lamp± (Canada only) to illuminate.

Only use premium unleaded gasoline with a
minimum Posted Octane Rating of 91 (average of
96 RON / 86 MON). Information on gasoline
quality can normally be found on the fuel pump.
For more information on gasoline, see the
Factory Approved Service Products pamphlet
(USA only) or contact an authorized
Mercedes-Benz Center.

!
If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark or
below, have the brake system checked for brake
pad thickness and leaks immediately. Notify an
authorized Mercedes-Benz Center immediately.
Do not add brake fluid as this will not solve the
problem. For more information, see “Practical
hints” (page 381).
461 Practical hints
Flat tire
Detach the electric air pump.
Store the electrical plug 3 and the air
hose 4 behind the flap 1 and place
the electric air pump back in the desig-
nated storage space underneath the
cargo compartment floor
(page 430).Lowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.
Remove the jack.
1-5 Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 96 lb-ft
(130 Nm).Before storing the jack, it should be fully
collapsed, with handle folded in (storage
position).
Store the jack and the other vehicle
tools in the designated storage space
underneath the cargo compartment
floor (
page 430).
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).i
Wrap the damaged wheel in the protective
film that comes with the spare wheel and put the
wheel in the cargo compartment.
Vehicles with TPMS or Advanced TPMS*:
Do not activate the tire inflation pressure moni-
tor until a full size wheel/tire with functioning
sensor has been placed back into service on the
vehicle.
490 Technical dataFuels, coolants, lubricants etc.Premium unleaded gasoline
Fuel requirements
Only use premium unleaded fuel:
The octane number (posted at the
pump) must be 91 min. It is an average
of both the Research Octane Number
(RON) and the Motor Octane Number
(MON): (RON+MON) / 2). This is also
known as the ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates
such as ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not
exceed 10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is
not allowed. Gasohol, which contains
10% ethanol and 90% unleaded gasoline,
can be used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.

sonal injury.
Never allow sparks, flame or smoking mate-
rials near gasoline!

!
To maintain the engine’s durability and per-
formance, premium unleaded gasoline must be
used. If premium unleaded gasoline is not avail-
able and low octane fuel is used, follow these
precautions:
Have the fuel tank only partially filled with
unleaded regular gasoline and fill up with
premium unleaded gasoline as soon as
possible.
Avoid full throttle driving and abrupt
acceleration.
Do not exceed an engine speed of 3 000 rpm
if the vehicle is loaded with a light load such
as two persons and no luggage.
Do not exceed
2/3 of maximum accelerator
pedal position if the vehicle is fully loaded or
operating in mountainous terrain.
