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.
Activating the cooling with air dehumidification function !
If the cooling with air dehumidification does not switch on, it is possible that the climate
control system has lost coolant.
Have the cooling with air dehumidification checked at a qualified specialist workshop. Canada only

WARNING
Fogged windows impair visibility,
endangering you and others. If the windows
begin to fog on the inside, switching off the
air recirculation mode immediately should
clear interior window fogging. If interior
window fogging persists, make sure the air
conditioning is activated, or press the 0064
button.
X Turn the SmartKey to position
2(Y page 139) in the ignition lock.
X To switch on: press the0089button.
The indicator lamp in the 0089button lights
up.
i Air-recirculation mode is automatically
activated at high levels of pollution or at
high outside temperatures. When air-
recirculation mode is activated
automatically, the indicator lamp in the
0089 button is not lit.
Outside air is added after approximately
30 minutes.
X To deactivate: press the0089button.
The indicator lamp in the 0089button goes
out.
i Air-recirculation mode switches off
automatically:
R after approximately five minutes at
outside temperatures below
approximately 41 ‡
R after approximately five minutes if
cooling with air dehumidification is
deactivated
R after approximately 30 minutes at
outside temperatures above
approximately 41 ‡ (5 †) Activating/deactivating the residual
heat function
The "residual heat" function is only available
in Canada.
It is possible to make use of the residual heat
of the engine to continue heating the
stationary vehicle for up to 30 minutes after
the engine has been switched off. The heating
time depends on the coolant temperature and
on the interior temperature that has been set.
i The blower will run at a low speed
regardless of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated.
X Turn the SmartKey to position
0(Y page 139) in the ignition lock or
remove it.
X To activate: press the0056button.
The indicator lamp in the 0056button lights
up.
X To deactivate: press the0056button.
The indicator lamp in the 0056button goes
out.
i Residual heat is deactivated
automatically:
R after approximately 30 minutes
R when the ignition is switched on
R if the battery voltage drops
R if the coolant temperature is too low Setting the air vents

WARNING
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature). This
could cause burns or frostbite to unprotected
skin in the immediate area of the air vents. 134

0050Solutions The coolant
temperature gauge
shows a value above
248 ‡(120 †). A
display message may
also appear in the
multifunction display
and a warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 285). Observe the warning
notes as you do so and add coolant if necessary. If the coolant level is correct, the radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled
sufficiently.
X
At coolant temperatures below 248 ‡ (120 †), drive to the
nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrain and start/stop traffic. Automatic transmission
Important safety notes
G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor
R, the vehicle could pull away suddenly. There
is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do
not simultaneously accelerate. G
WARNING
The automatic transmission switches to
neutral position Nwhen you switch off the
engine. The vehicle may roll away. There is a
risk of an accident.
After switching off the engine, always switch
to parking position P. Prevent the parked
vehicle from rolling away by applying the
parking brake.
i Bear in mind that the power transmission
between the engine and the transmission
is interrupted when the engine is switched
off. For this reason, shift the automatic
transmission to Pwhen the engine is
switched off and the vehicle is at a standstill. Apply the parking brake to
prevent the vehicle from rolling away. Selector lever
Overview of transmission positions !
If the engine speed is too high or if the
vehicle is rolling, do not shift the
transmission directly from Dto R, from R
to Dor directly to P.
Do not open the driver's door while the
vehicle is in motion. At low speeds in
transmission position Dor R, park position
P is otherwise engaged automatically.
The transmission could be damaged. Automatic transmission

WARNING
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.

temperature is too high. Displays and ope

If the coolant temperature is over
248 ‡(120 †), do not continue driving. The
engine will otherwise be damaged.
The coolant temperature gauge is in the
instrument cluster on the right-hand side
(Y page 205).
Under normal operating conditions and with
the specified coolant level, the coolant
temperature may rise to 248 ‡ (120 †). Tachometer
! Do not drive in the overrevving range, as
this could damage the engine.
The red band in the tachometer indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached. Outside temperature display
G
WARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
The outside temperature display is in the
multifunction display (Y page 207).
Changes in the outside temperature are
displayed after a short delay. Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
R Cruise control activated (Y page 168):
The segments light up from the stored
speed to the maximum speed.
R Variable SPEEDTRONIC activated
(Y page 174): The segments light up from the start of the
scale to the selected limit speed.
