Air-conditioning system Below, you can find a number of notes and
recommendations to help you use the air-
conditioning system optimally.
R Switch on climate control using the 005A
button. The indicator lamp in the 005A
button lights up.
R Set the temperature to 72 ‡ (22 †).
R Recommendation for air distribution in
winter: set the009Band0061 settings.
Recommendation for air distribution in
summer: set the009Csetting.
R Only use the "Windshield defrosting"
function briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
ECO start/stop function During automatic engine switch-off, the ECO
start/stop function only operates at a
reduced capacity. If you require full climate
control capacity, the ECO start/stop function
can be deactivated by pressing the ECO
button (Y page 145). 124

air dehumidification
General notes If you deactivate the "Cooling with air-
dehumidification" function, the air inside the
vehicle will not be cooled. The air inside the
vehicle will also not be dehumidified. The
windows can fog up more quickly. Therefore,
deactivate the cooling with air-
dehumidification function only briefly.
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.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a
malfunction.Operating the climate control systems

If cylinder shut-off is not active, the engine
will operate with all eight cylinders. In this
case, the number of active cylinders 8is
shown in the 00A7symbol.
Automatic engine switch-off Method of operation
The ECO start/stop function is operational
and the 00A7symbol is displayed in green in
the multifunction display, if:
R the indicator lamp in the ECO button is lit
green.
R the outside temperature is within the
comfort range.
R the engine is at normal operating
temperature.
R the set temperature for the vehicle interior
has been reached.
R the battery is sufficiently charged.
R the system detects that the windshield is
not fogged up when the air-conditioning
system is switched on.
R the hood is closed.
R the driver's door is closed and the driver's
seat belt is fastened.
If not all conditions for automatic engine
switch-off are fulfilled, the 00A7symbol is
shown in yellow.
i All of the vehicle's systems remain active
when the engine has been stopped
automatically.
i All vehicles (apart from AMG
vehicles): automatic engine switch-off can
take place a maximum of four times
consecutively (initial stop then repeated
three times). The 00A7symbol is shown in
yellow in the multifunction display after the
engine has been started automatically for
the fourth time. When the 00A7symbol is
shown in green in the multifunction display,
automatic engine switch-off is again
possible. i
AMG vehicles: times which the engine
can be automatically switched off.
i The HOLD function can be activated if the
engine has been switched off
automatically. It is then not necessary to
continue applying the brakes during the
automatic stop phase. When you depress
the accelerator pedal, the engine starts
automatically and the braking effect of the
HOLD function is deactivated.
Vehicles with manual transmission The ECO start/stop function switches off the
engine automatically at low speeds.
X Brake the vehicle.
X Engage neutral N(follow gearshift
instruction 0043to engage neutral N, if
necessary).
X Release the clutch pedal.
The engine is switched off automatically.
Vehicles with automatic transmission
If the vehicle is braked to a standstill in Dor
N, the ECO start/stop function switches off
the engine automatically.
Automatic engine start Method of operation
The engine starts automatically if:
R
you switch off the ECO start/stop function
by pressing the ECO button.
R you engage reverse gear R.
R you switch to drive program Sor M(AMG
vehicles).
R you unfasten your seat belt or open the

If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the
airflow to cool the brakes more quickly.
Wet roads If you have driven for a long time in heavy rain
without braking, there may be a delayed
reaction from the brakes when braking for the
first time.
This may also occur after driving through
water deep enough to wet brake
components.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the
vehicle washed, brake firmly while paying
attention to the traffic conditions. This will
warm up the brake discs, thereby drying them
more quickly and protecting them against
corrosion.
Limited braking performance on salt-
treated roads If you drive on salted roads, a layer of salt
residue may form on the brake discs and
brake pads. This can result in a significantly
longer braking distance.
R Brake occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
R Carefully depress the brake pedal and the
beginning and end of a journey.
R Maintain a greater distance to the vehicle
ahead.
High performance and ceramic brake
system for AMG vehicles The high-performance brake system is
installed only on the SLK 55 AMG. The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This will depend on:
R speed
R braking force
R ambient conditions, e.g. temperature and
humidity
The wear of individual components of the
brake system, such as the brake pads/linings
or brake discs, depends on the individual
driving style and operating conditions.
For this reason, it is impossible to state a
mileage that will be valid under all
circumstances. An aggressive driving style
will lead to high wear. You can obtain more
information on this from a qualified specialist
workshop.
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applying greater force
to the brake pedal. Keep this in mind, and
adapt your driving and braking accordingly
during this break-in period.
Excessive heavy braking results in
correspondingly high brake wear. Observe
the brake system warning lamp in the
instrument cluster and note any brake status
messages in the multifunction display. For
high-performance driving in particular, it is
important to maintain and have the brake
system checked regularly.
Servicing the brakes !
If the red brake warning lamp lights up in
the instrument cluster and you hear a
warning tone while the engine is running,
the brake fluid level may be too low.
Observe additional warning messages in
the multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked
immediately. This work should be carried
out at a qualified specialist workshop. Driving tips
