The yellow
Check Engine
indicator lamp is
lit while the
engine is run-
ning. The exhaust gas aftertreatment is malfunctioning or an emission
relevant malfunction has occurred. This malfunction or defect can
damage the exhaust gas aftertreatment.
After the first message and under normal operating conditions,
you can drive on for up to approximately 500 mi (800 km). Then a
warning tone sequence sounds and the engine can only be started another 16 times.
X Observe the messages in the display.
X Have the exhaust gas aftertreatment checked immediately at a
qualified specialist workshop.
In some states it is legally prescribed that after the check engine
indicator lamp lights up you must contact a qualified specialist
workshop immediately. Observe the legal requirements. 0028
If you turn the
key to position 2
in the ignition
lock, the yellow
preglow indica-
tor lamp
remains lit for
approximately
1 minute. Or the
yellow preglow
indicator lamp
lights up for
approximately
1 minute while
the engine is
running. At extremely low temperatures, the engine may not start.
There is a malfunction in the preglow system.
X Have any malfunction rectified at a qualified specialist work-
shop. 009F
The yellow air fil-
ter indicator
lamp is lit while
the engine is
running. The service limit for the air filter has been reached. The air filter is

tion lock, the
yellow bulb
warning lamp
lights up. One of the exterior lighting bulbs is faulty, with the exception of the
perimeter lamps and the trailer lighting.
i Depending on the equipment, the bulb failure indicator can fail
for all lamps with the exception of the turn signal lamps.
X Replace the faulty bulb as soon as possible (Y page 99).003E

Washer fluid
G
WARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit. Unsuitable washer fluid
could damage the plastic lenses of the
headlamps. Example: washer fluid reservoir
Add windshield washer concentrate to the
washer fluid all year round. Observe the infor- mation on washer fluid in the "Technical data"
section (Y page 326).
Adding washer fluid
X Mix the washer fluid to the appropriate mix-
ing ratio in a container beforehand.
X Open the hood (Y page 248).
X Pull cap 0043on the washer fluid reservoir
upwards at the tab.
X Add the premixed washer fluid.
X Press cap 0043onto the filler neck until it
engages audibly.
X Close the hood. Fuel system

WARNING
Fuel is highly flammable. Improper handling of fuel creates a risk of fire and explosion.
Avoid fire, open flames, smoking and creatingsparks under all circumstances. Switch off the
ignition and auxiliary heating before carrying
out work to the fuel system. Always wear pro- tective gloves. H
Environmental note
Dispose of the water-fuel mixture in an envi-
ronmentally responsible manner.
! When the
00B8indicator lamp lights up,
drain the fuel filter with water separator
immediately. Otherwise, the engine may be
damaged. If the
00B8 indicator lamp in the instrument
cluster goes on, drain fuel filter with water
separator 0087immediately.
i We recommend that you have this main-
tenance work carried out at a qualified spe-
cialist workshop.
X Park the vehicle safely and secure it from
rolling away.
X Switch off the auxiliary heating system .
X Switch off the engine.
X Open the hood (Y page 248).

standstill. Do not carry out any sudden steer-
ing maneuvers.
The tire pressure monitor has a yellow 0077
warning lamp in the instrument cluster for
indicating pressure loss/malfunctions (USA)
or pressure loss (Canada). Depending on how
the warning lamp flashes or lights up, an
underinflated tire or a malfunction in the tire
pressure monitor is displayed:
R if the 0077 warning lamp is lit continuously,
the tire pressure on one or more tires is
significantly too low. The tire pressure mon-
itor is not malfunctioning.
R USA only: if the 0077warning lamp flashes
for 60 seconds and then remains lit con-
stantly, the tire pressure monitor is mal-
functioning.
Only vehicles with steering wheel buttons: the on-board computer displays information on
tire pressure. After a few minutes of driving,
the current tire pressure of each tire is shown
in the on-board computer.
USA only: if the tire pressure monitor is mal-
functioning, it may be more than 10 minutes
before the malfunction is shown. The 0077
tire pressure warning lamp flashes for
60 seconds and then remains lit. When the
malfunction has been rectified, the 0077tire
pressure warning lamp goes out after a few
minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gage.
The tire pressures shown by the on-board
computer refer to those measured at sea
level. At high altitudes, the tire pressure val-
ues indicated by a pressure gage are higher
than those shown by the on-board computer. In this case, do not reduce the tire pressures.
If radio transmitting equipment (e.g. wireless headphones, two-way radios) is operated
inside the vehicle or in the vicinity of the vehi-
cle, this can interfere with the operation of the tire pressure monitor. Checking the tire pressure electroni-
cally (vehicles with steering wheel but-
tons)
Tire pressure display
Using the steering wheel buttons
X Turn the key to position 2in the ignition
lock.
X Press the 0080or007F button repeatedly
until the standard display is shown
(Y page 187).
X Press the 0063or0064 button repeatedly
until the current pressure of the individual
tires is shown in the display.
If the vehicle is parked for longer than
20 minutes or you then drive at less than
18 mph (30 km/h), the Tire pres. dis‐ Tire pres. dis‐
played after driving for several played after driving for several
minutes minutes message appears.
i The tire pressure value shown in the dis-
play may differ from those measured at a
gas station using a pressure gage. The on-
board computer will generally give you a
more exact value.
Tire pressure loss warning system Vehicles with steering wheel buttons
If the tire pressure monitor detects a signifi-
cant pressure loss on one or more tires, the
on-board computer displays a warning mes-
sage. The 0077tire pressure loss warning
lamp in the instrument cluster (Y page 226)
lights up.
The tire pressure is shown in 2 red rectangles. The pressure of the tire concerned is shown in
one of the two rectangles (Y page 197). Addi-
tionally, a warning tone sounds. 292
