WARNING
The sliding sunroof is made out of glass. In the
event of an accident, the glass may shatter.
This may result in an opening in the roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening
also presents a potential for injury for
occupants wearing their seat belts properly,
as entire body parts or portions of them may
protrude from the passenger compartment.
! Only open the sliding sunroof if it is free
of snow and ice. Otherwise, malfunctions
may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.
! The weather can change abruptly. It could
start to rain or snow. Make sure that the
sliding sunroof is closed when you leave the
vehicle. The vehicle electronics can be
damaged if water enters the vehicle
interior.
i Resonance noises can occur in addition
to the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.
Change the position of the sliding sunroof
or open a side window slightly to reduce or
eliminate these noises. Operating the sliding sunroof

X Turn the SmartKey to position 1
or 2 in the
ignition lock.
X Press or pull the 3 switch in the
corresponding direction.
i If you press the 3 switch beyond the
point

of resistance, an automatic opening/
closing process is started in the
corresponding direction. You can stop
automatic operation by operating the
switch again.
The automatic opening and raising feature
is available only when the sliding sunroof is
closed.
The sun protection cover automatically opens
along with the sliding sunroof. You can open
or close the sun protection cover manually
when the sliding sunroof is raised or closed.
i You can continue to operate the sliding
sunroof after switching off the engine or
removing the SmartKey from the ignition
lock. This function remains active for five
minutes or until you open a front door.
Resetting !
If the sliding sunroof still cannot be
opened or closed fully after resetting,
contact a qualified specialist workshop. Sliding sunroof

significantly influence the vehicle's
consumption.
The ECO display consists of three bars:
R
Acceleration
R Constant
R Coasting
The
percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%. A higher
percentage indicates a more economical
driving style.
The ECO display does not provide any
information on the actual consumption. A
fixed percentage count in the ECO display
does not indicate a fixed consumption figure
in l/100 km.
Apart from driving style, consumption is
dependent on many factors such as, e.g.:
R Load
R Tire pressure
R Cold start
R Choice of route
R Electrical consumers switched on
These factors are not taken into
consideration by the ECO display.
The evaluation of your driving style is carried
out using the following three categories:
Acceleration (evaluation of all
acceleration) The bar fills up: The bar empties:
Moderate
acceleration,
especially at high
speeds Sporty acceleration Constant (evaluation of driving style at
any time)
The bar fills up: The bar empties:
Constant speed and
avoidance of
unnecessary
acceleration and
deceleration Speed variations
Coasting (evaluation of total
deceleration)
The bar fills up: The bar empties:
Drive with care and
remove your foot
from

the accelerator
pedal in good time:
the vehicle can
coast without
braking Frequent braking
i
An economical driving style specially
requires driving at moderate engine
speeds.
Achieving a higher value in the categories
"Acceleration" and "Constant":
R observe

the gearshift recommendations.
R drive in drive program E.
i On longer journeys, e.g. on highways, the
only the bar in the "Constant" category
changes.
i The ECO display calculates the driving
style from the start of the journey to the
end. For this reason, the bars change
dynamically at the beginning of the journey.
On longer journeys, there are fewer
changes. For more dynamic changes, carry
out a manual reset.

Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g.
R18. The rim diameter is part of the tire size
and can be found on the tire sidewall
(Y page 342).
If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset
to the higher values:
R
if you want to drive with an increased load
and/or
R if you want to drive at higher road speeds.
i The tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may have a negative
effect on driving comfort.
If the tire pressure is not set correctly, this
can
lead to an excessive build up of heat and
a sudden loss of pressure.
For more information, contact a qualified
specialist workshop. Important notes on tire pressure
G
WARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident.
R Check the tire for foreign objects.
R Check

whether the wheel is losing air or the
valve is leaking. If you are unable to rectify the damage,
contact a qualified specialist workshop.
G
WARNING
If you fit unsuitable accessories onto tire
valves,
the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire
pressure monitors keep the tire valve open.
This can also result in tire pressure loss. There
is a risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
Use a suitable pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion about
the tire pressure. On vehicles equipped with
the electronic tire pressure monitoring
system, the tire pressure can be checked
using the on-board computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is
dependent on the driving speed and the load.
Therefore, you should only correct tire
pressures 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 been driven for less than
1 mile (1.6 km).
The tire temperature changes depending on
the outside temperature, 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). Take this into account when
checking 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
resulting value will be higher than if the tires
were cold. This is normal. Do not reduce the
tire pressure to the value specified for cold Tire pressure
