S Standard For regular driving
W Winter For winter driving
Press program mode selector
switch1.
SelectWfor winter driving:
The vehicle starts out in second
gear (both forward and reverse) for
gentler starts. This does not apply if
full throttle is applied or gear
range1 is selected.
Traction and driving stability are
improved on icy roads.
Upshifts occur earlier even when
y ou gi ve m ore ga s. The eng ine then
operates at lower rpms and the
wheels are less likely to spin.
The power transmission ratio for
gear selector lever positionR
changes depending on the program
mode selected (SorW).
Warning!
G
When leaving the vehicle, always remove the
key from the steering lock, take it with you
and lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Children could move
the gear selector lever from positionP,
which could result in an accident and/or
serious personal injury.
!Never change the program mode when
the gear selector lever is out of
positionP. This could result in a
change of driving characteristics for
which you may not be prepared.

Your driving style influences the
transmission’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
Press the accelerator past the point of
resistance.
The transmission shifts into a lower
gear.
Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.Emergency operation (Limp Home
Mode)
If vehicle acceleration worsens or the
transmission no longer shifts, the trans-
mission is most likely operating in limp
home (emergency operation) mode. In this
mode only second gear and reverse gear
can be activated.
Stop the vehicle.
Move gear selector lever toP.
Turn off the engine.
Wait at least ten seconds before
restarting.
Restart the engine.
Move gear selector lever to positionD
(for second gear) orR.
Have the transmission checked at an
authorized Mercedes-Benz Center as
soon as possible.

Sun visors
The sun visors protect you from sun glare
while driving.
Warning!
G
The automatic antiglare function does not
react if incoming light is not aimed directly
at sensors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, if the wind screen is in-
stalled.
Glare can endanger you and others.Warning!
G
In the case of an accident, liquid electrolyte
may escape from the mirror housing if the
mirror glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or the respiratory sys-
tem. In case it does, immediately flush af-
fected area with water, and seek medical
help if necessary.
Warning!
G
Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes.!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state by applying plenty of water.
Warning!
G
Do not use the vanity mirror while driving.
Keep the mirrors in the sun visors closed
while vehicle is in motion. Reflected glare
can endanger you and others.

Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the defrost-
er as soon as the rear window is clear. The
defroster is automatically deactivated af-
ter a maximum of 12 minutes.
Activating
Switch on the ignition.
Press buttonF (
page 102).
The indicator lamp on the button lights
up.
Deactivating
Press buttonF (
page 102) again.
The indicator lamp on the button goes
out.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.!If the rear window defroster switches
off too soon and the indicator lamp
starts blinking, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.

Climate control
The climate control is operational whenev-
er the engine is running. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent outside temperature.
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the AC
OFF
mode is selected.

Warning
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents in the footwell can be
very hot or very cold (depending on the set
temperature). This may cause burn or frost-
bite to unprotected skin in the immediate
area of the air vents. Always keep sufficient
distance between unprotected parts of the
body and the footwell air vents. If necessary
change the air flow using the air distribution
controls to direct the air away from the foot-
well air vents.Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.

Setting the temperature
Use temperature controls5 (
page 103)
to separately adjust the air temperature on
each side of the passenger compartment.
You should raise or lower the temperature
setting in small increments, preferably
starting at 72°F (22°C).Increasing
Turn the temperature control5
slightly upwards.
A red marking will be visible and the
climate control system will correspond-
ingly adjust the interior air tempera-
ture.
iThe selected temperature is reached as
quickly as possible.
Severe conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval. A
clogged filter will reduce the air volume
to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.
iIf you use the standard settings for
heating or cooling the passenger com-
partment (
page 102), you will rarely
need to change the temperature, air
volume or air distribution.
