The engin eoil level has dropped to th eminimum level.
A warnin gtone also sounds.
!Avoid lon gjourneys wit hto olittl eengin eoil. The engin ewill
otherwise be damaged.

Fuel Level Low
The fuel level has dropped into the reserve range.
XRefuel at the nearest gas station.
CThere is only a very small amount of fuel in the fuel tank.
XRefuel at the nearest gas station without fail.

Gas Cap Loose
The fuel system pressure is too low. The fuel filler cap is not closed
correctly or the fuel system is leaking.
XCheck that the fuel filler cap is correctly closed.
If the fuel filler cap is not correctly closed:
XClose the fuel filler cap.
If the fuel filler cap is correctly closed:

Maintenance and care
Z

!Please note the care instructions in the
trailer coupling manufacturer's operating
instructions.
The ball coupling must be cleaned if it
becomes dirty or corroded.
XRemove rust on the ball, e.g. with a wire
brush.
XRemove dirt with a clean, lint-free cloth or a brush.
XAfter cleaning, lightly oil or grease the ball
coupling.
XCheck that the vehicle's trailer tow hitch is
working properly.
iYou can also have the maintenance work
on the ball coupling and the trailer tow hitch
carried out by a qualified specialist work-
shop.
Interior care
Cleaning the display
!For cleaning, do not use any of the fol-
lowing:
Ralcohol-based thinner or gasoline
Rabrasive cleaning agents
Rcommercially-available household clean-
ing agents
These may damage the display surface. Do not put pressure on the display surface
when cleaning. This could lead to irrepara-
ble damage to the display.
XBefore cleaning the display, make sure thatit is switched off and has cooled down.
XClean the display surface using a commer-
cially available microfiber cloth and
TFT/LCD display cleaner.
XDry the display surface using a dry micro-
fiber cloth.
Cleaning the plastic trim
GWARNING
Care products and cleaning agents containing solvents cause surfaces in the cockpit to
become porous. As a result, plastic parts may
come loose in the event of air bag deploy-
ment. There is a risk of injury.
Do not use any care products and cleaning
agents to clean the cockpit.
!Do not affix the following to plastic surfa-
ces:
Rstickers
Rfilms
Rscented oil bottles or similar items
You can otherwise damage the plastic.
!Do not allow cosmetics, insect repellent
or sunscreen to come into contact with the
plastic trim. This maintains the high-quality
look of the surfaces.
XWipe the plastic trim with a damp, lint-free
cloth, e.g. a microfiber cloth.
XHeavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
The surface may change color temporarily.
Wait until the surface is dry again.
Cleaning the steering wheel and gear or
selector lever
XThoroughly wipe with a damp cloth or use
leather care agents that have been recom-
mended and approved by Mercedes-Benz.
Cleaning genuine wood and trim ele-
ments
!Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, pol-
ishes or waxes. There is otherwise a risk of
damaging the surface.
!Do not use chrome polish on trim pieces.
The trim pieces have a chrome look but are
mostly made of anodized aluminum and

housing.
XScrew hose Aonto flange Bof tire seal-
ant bottle :.
XPlace tire sealant bottle :head down-
wards into recess ;of the tire inflation
compressor.
XRemove the cap from valve Con the faulty
tire.
XScrew filler hose Donto valve C.
XInsert connector ?into a socket in your
vehicle.
Cigarette lighter socket: (
Ypage 320)
12 V socket: (
Ypage 321)
Observe the notes on the cigarette lighter
(
Ypage 320). Observe the notes on sock-
ets (
Ypage 321).
XTurn the SmartKey to position 1in the igni-
tion lock (
Ypage 153).
XPress on and off switch =on the tire infla-
tion compressor.
The tire inflation compressor is switched
on. The tire is inflated.
First, tire sealant is pumped into the tire.
The pressure may briefly rise to approx-
imately 500 kPa (5 bar/73 psi).
Do not switch off the tire inflation com-
pressor during this phase.
XLet the tire inflation compressor run for a
maximum of five minutes. The tire should
then have attained a pressure of at least
180 kPa (1.8 bar/26 psi). If a pressure of 180 kPa (1.8 bar/26 psi) has
been attained after five minutes, see "Tire
pressure reached" (
Ypage 359).
If a tire pressure of 180 kPa (1.8 bar/26 psi)
has not been attained after five minutes, see
"Tire pressure not reached" (
Ypage 359).
If tire sealant has escaped, clean it off affec-
ted areas as quickly as possible. Use plain
water if possible.
If your clothes are soiled with tire sealant,
have them cleaned with perchloroethylene at
a dry cleaner as soon as possible.
Tire pressure not reached
If a pressure of 180 kPa (1.8 bar/26 psi) has
not been attained after five minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of
the faulty tire.
Note that tire sealant may escape when you
unscrew the filler hose.
XVery slowly drive forwards or reverse
approximately 30 ft (10 m).
XPump up the tire again.
After a maximum of five minutes the tire
pressure must be at least 180 kPa (1.8 bar/ 26 psi).
GWARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and a tire
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
