Refueling
The fuel filler flap is located on the
right-hand side of the vehicle towards the
rear. Locking/unlocking the vehicle with
the SmartKey or the SmartKey with
KEYLESS-GO* automatically
locks/unlocks the fuel filler flap.
Turn the engine off
by turning the SmartKey to
position0. Remove the SmartKey
from the starter switch.
by pressing the KEYLESS-GO*
start/stop button (
page 35).
Open the driver’s door (with the
driver’s door open, starter switch is
now in position0, same as
SmartKey removed from 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.
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 over-
fill.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
injury. Whenever you are around gasoline,
avoid inhaling fumes and skin contact, extin-
guish all smoking materials. Never allow
sparks, flame or smoking materials near
gasoline!
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.

324 OperationAt the gas station
Replace the fuel cap by turning it
clockwise until it audibly engages.
Close the fuel filler flap.
Check regularly and before a long trip
Open the hood (
page 326).

Engine oil level
For more information on engine oil, see
“Engine oil” (
page 327).Brake fluid
Coolant
For normal replenishing, use water (pota-
ble water quality).
For more information, see “Coolant level”
(
page 332) and see “Fuels, coolants, lu-
bricants, etc.” (
page 493).
iOnly 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.iLeaving the engine running and the fuel
cap open can cause the yellow engine
malfunction indicator lamp
?(USA only), ±(Canada only)
to illuminate.
For more information, see “Practical
hints” (
page 385).
!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. Noti-
fy an authorized Mercedes-Benz Light
Truck Center immediately. Do not add
brake fluid as this will not solve the
problem. For more information, see
“Practical hints” (
page 381).

351 Operation
Tires and wheels
Checking tire pressure electronically
with the Advanced Tire Pressure Moni-
toring System* (Advanced TPMS*)The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, as selected by the driver, in all four
tires. A warning is issued to alert you to a
decrease in pressure in one or more of the
tires.
Tire pressure inquiries are made using the
multifunction display.The present inflation
pressures are displayed only after a few
minutes’ travel time.
Switch on the ignition (
page 34).
Press thej or kbutton until
the current inflation pressures for each
tire appear in the multifunction display.
iThe Advanced T
ire P
ressure M
onitoring
S
ystem* (Advanced TPMS*) is
equipped with a combination low tire
pressure/TPMS malfunction telltale in
the instrument cluster (
page 24). De-
pending on how the telltale illuminates,
it indicates a low tire pressure condi-
tion or a malfunction in the TPMS sys-
tem itself:
If the telltale illuminates continu-
ously, one or more of your tires is
significantly under-inflated. There is
no malfunction in the TPMS.
If the telltale flashes for 60 seconds
and then stays illuminated, the
TPMS system itself is not operating
properly.
iPossible differences between the read-
ings of a tire pressure gauge of an air
hose, e.g. gas station equipment, and
the vehicle’s control system can occur.
Usually the readings issued by the con-
trol system are more precise.
iWhen the message
Tire pressure
display appears after driving sev-
eral minutes
appears in the display,
the individual inflation pressure values
are matched with the tires. The individ-
ual values are displayed after a few
minutes driving.
iWith a spare wheel without wheel sen-
sor mounted, the system may still indi-
cate the tire inflation pressure of the
removed wheel for some minutes. If
this happens, keep in mind that the in-
dicated value where the spare wheel is
mounted does not reflect the actual
spare tire inflation pressure.
