General notes Depending on the driving style, the vehicle
consumes up to 0.9 US qt (0.8 l) of oil over a
distance of 600 miles (1000 km). The oil con- sumptio nmay be higher than this whe nthe
vehicle is new or if yo ufrequently drive at high
engine speeds.
Depending on the engine, the oil dipstick may
be in adifferent location.
Whe nchecking the oil level:
R park the vehicle on aleve lsurface.
R the engine should be switched off for
approximatel yfive minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine wa sonly
started briefly ,waita bout 30 minutes
before carrying out the measurement.

X Stop afte rdriving for approximatel yten
minutes and check the tire pressure with
the tire inflation compressor.
The tire pressure mus tnow be at least
130 kPa (1.3 bar/19 psi).
i On tire
stha tare equipped with atire pres-
sure sensor (tire pressure monitor) ,the use
of sealant can lead to malfunction mes-
sages and incorrect displays. Therefore,
us ep ressure gauge 0084in the TIREFIT kit to
check and correct the tire pressure. G
WARNING
If the required tire pressure is not reached

130 kPa (1.3 bar/20 psi )(fort he values,
see the Tire and Loading Information plac-
ard on the driver' ssideB -pillar or tire pres-
sure table on the fue lfille rflap).
To increase the tire pressure: switch on

If the tire pressure is not set correctly, this
can leadtoane xcessive build up of heat and
as udden loss of pressure.
For more information, contact aqualified spe-
cialist workshop. Important notes on tire pressure
G
WARNING
If the tire pressure drops repeatedly,t he
wheel, valve or tire may be damaged. Tire
pressure that is too low may resultina tire
blow-out. There is arisk of an accident.
R Check the tire for foreign objects.
R Check whether the wheelisl osing air or the
valve is leaking.
If you are unabletor ectify the damage, con-
tact aqualifieds pecialist workshop. G
WARNING
If you fit unsuitable accessorie sonto tire
valves ,the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire pres- sure monitors keep the tire valve open. This
can also resultint ire pressure loss. There is a
risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
yourv ehicle onto the tire valve.
Use asuitable pressure gauge to check the
tire pressure. The outer appearance of atire
does not permit any reliable conclusion about the tire pressure. On vehicle sequippedw ith
the electronic tire pressure monitor, the tire
pressure can be checked in the on-board
computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is depend-
ent on the driving speed and the load.
Therefore ,you shouldo nly correct tire pres-
sures when the tires are cold. The tires are cold:
R if the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
R if the vehicle has not been driven further
than 1mile (1.6 km)
The tire temperature changes depending on
the outsid etemperature ,the vehicle speed
and the tire load. If the tire temperature
changes by 18 ‡(10 †), the tire pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi).T ake this into account when check-
ing the pressure of warm tires. Only correct
the tire pressure if it is too low for the current
operating conditions. If you check the tire
pressure when the tires are warm, the result- ing valuew illbeh igherthan if the tires were
cold. This is normal. Do not reduce the tire
pressure to the values pecified for cold tires.
The tire pressure would otherwis ebetoo low.
Observe the recommended tire pressures for
cold tires:
R on the Tire and Loading Information placard
on the B-pilla ronthe driver's side
R in the tire pressure table on the inside of the
fuel filler flap Underinflated or overinflated tires
Underinflated tires G
WARNING
Tires with pressure that is too low can over-
heat and burst as aconsequence. In addition,
they also suffer from excessive and/or irreg-
ularw ear, which can severel yimpair the brak-
ing propertie sand the driving characteristics.
There is arisk of an accident.
Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires may:
R overheat, leading to tire defects
R adversely affect handling Tire pressure
