Switching the control on/off
Important information
GWarning!
When the climate control system is
deactivated, the outside air supply and
circulation are also deactivated. Only choose
this setting for a short time. Otherwise the
windows could fog up, impairing visibility and
endangering you and others.
i Activate climate control primarily using
the à button ( Y page 123).

dehumidification on/off
Important information
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
GWarning
If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
Condensation may drip from the underside of
the vehicle when automatic climate control is
in cooling mode. This is normal and not a sign
that there is a malfunction.
i The cooling with air dehumidification
function uses refrigerant R134a. This
coolant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer.
Activating/deactivating
i The evaporator is ventilated when the air-
conditioning system is operated. The
blower switches on automatically
approximately one hour after the vehicle is
locked. The blower runs for 30 minutes on
the lowest level. The blower noise is normal
and not a sign that there is a malfunction.
If you unlock the vehicle during this time,
the ventilation will be interrupted. To save
battery power, the evaporator will not

ProblemPossible causes/consequences and M SolutionsThe engine is not
running smoothly and
is misfiring.
There is a malfunction in the engine electronics or a mechanical
component of the engine management system.
XOnly depress the accelerator pedal slightly.XHave the cause rectified immediately at a qualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic
converter and damage it.
The coolant
temperature gauge
shows a value above
248 ‡(120 †).
The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant
to cool down.
XCheck the coolant level (Y page 240). Observe the warning
notes as you do so and add coolant if necessary.Manual transmission
Important safety notes
GWarning
When working on the vehicle, engage the
parking brake and shift the manual
transmission into the 1st gear or reverse R.
The vehicle could otherwise roll away, which
could result in an accident and/or serious
personal injury.
Gear lever
Gear lever
kReverse1 to 6Forward gears! When shifting between 5th and 6th gear,
you should always push the gear lever all
the way to the right. You could otherwise
shift unintentionally into 3rd or 4th gear
and damage the transmission.
If you shift down at too high a speed
(transmission braking), this can cause the
engine to overrev, leading to engine
damage.
Never hold the vehicle stopped on a hill by
using the clutch pedal. There is otherwise
a risk of damaging the clutch.
Engaging reverse gear
! Only shift into reverse gear R when the
vehicle is stationary as you can otherwise
damage the transmission.
XStop the vehicle.XDepress the clutch pedal fully.XShift to neutral.XMove the gear lever firmly to the left
beyond the point of resistance and then
forwards.

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.
Important safety notes
You will find an illustration of the instrument
cluster in the "At a glance" section
( Y page 26).
GWarning
A driver's attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h ), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
GWarning!
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
R speed
R outside temperature
R warning/indicator lamps
R malfunction/warning messages
R failure of any systems
Driving characteristics may be impaired.
If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible.GWarning
Malfunction and warning messages are only
indicated for certain systems and are
intentionally not very detailed. The
malfunction and warning messages are
simply a reminder with respect to the
operation of certain systems. They do not
replace the owner's and/or driver's
responsibility to maintain the vehicle's
operating safety. Have all required
maintenance and safety checks performed on
the vehicle. Bring the vehicle to an authorized
Mercedes-Benz Center to address the
malfunction and warning messages.
Displays and operation
Coolant temperature gauge
GWarning
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
The coolant temperature gauge is in the
instrument cluster on the right-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant
temperature may rise to 248 ‡ (120 †).
! If the coolant temperature is too high a
display message is shown.
