heat function
It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off .The heating
time depends on the temperature that has
been set.
Depending on the equipment level, the con-
trol panel has either the Ìbutton or the
Á button.
i The blower will run at a low speed regard-
less of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.
X Turn the key to position 0in the ignition

R when the ignition is switched on
R if the battery voltage drops
R if the coolant temperature is too low Adjusting the air vents
Important safety notes

WARNING
Very hot or very cold air can flow from the air
vents.T his could cause burns or frostbite to
bare skin in the immediate vicinity of the
vents.K eep bare skin away from these air
outlets. If necessary, direct the airflow away
to a different area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet grille on the bonnet and
in the engine compartment on the front-
passenger side free of blockages, such as
ice, snow or leaves.
R never cover the vents or ventilation grilles
in the vehicle interior.
i You can move the adjuster sfor the air
vents vertically or horizontally, to set the
direction of the airflow.
i Optimal climate control function is ach-
ieved by opening the air vents fully and set-
ting the adjusters to the middle position. 122

Problem Possible causes/consequences and
M Solutions
The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit 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 251). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X If the coolant temperature is less than 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop-start traffic. Manual transmission
Important safety notes
G
WARNING
The movement of the pedals must not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you
to lose control of your vehicle and cause an
accident. Gear lever
Gear lever
!
Only engage gear when the clutch pedal
is depressed.
! When shifting between 5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift unintentionally into 3rdor4th gear
and damage the transmission.
If you shift down at too high a speed (trans-
mission braking), this can cause the engine
to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients.
There is otherwise a risk of damaging the
clutch. Manual transmission

Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 22).Important safety notes
You will find an illustration of the instrument
cluster in the "At a glance" section
(Y page 28). G
WARNING
Only use the on-board computer when road
and traffic conditions permit .You would oth-
erwise be distracted and unable to concen-
trate properly on driving, and could cause an
accident. G
WARNING
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such as
speed, outside temperature, warning and indi-
cator lamps, display messages or system fail-
ures. Driving characteristics may be impaired.
Adjust your driving style and vehicle speed
accordingly.
Contact a qualified specialist workshop
immediately. G
WARNING
The on-board computer only records and dis-
plays malfunctions and warnings from certain
systems. For this reason, you should always make sure that your vehicle is safe to use. You
could otherwise cause an accident by driving
an unsafe vehicle.
G
WARNING
The operating safety of your vehicle could be
impaired if maintenance work is carried out
incorrectly. This could cause you to lose con-
trol of your vehicle and cause an accident.
Moreover, the safety systems may no longer
be able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop. Displays and operation

Displays and operationOn-board computer and displays

The reading may rise up to 120
†undernor-
mal driving conditions if the coolant has been
filled correctly.
At high outside temperatures and when driv-
ing uphill, the coolant temperature may rise
to the end of the scale. Rev counter
The red band in the rev counter indicates the
engine's overrevving range.
! Do not drive in the overrevving range.
Doing so will damage the engine.
The fuel supply is interrupted to protec tthe
engine when the red band is reached. Outside temperature display
The outside temperature displayi s in the mul-
tifunction display (Y page 180). G
WARNING
At temperatures just above freezing point, the
street may be icy, especially in wooded areas
or on bridges. If you do not adapty our driving
style to the conditions, the vehicle could skid.
For this reason, adapt your driving style and
speed to the weather conditions.
Changes in the outside temperature are dis-
played after a short delay. Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
Cruise control (Y page 151) activated:
The segments light up from the stored speed
to the maximum speed.
Variable SPEEDTRONIC (Y page 153) activa-
ted:
The segments light up from the start of the
scale to the selected limit speed.
DISTRONIC PLUS (Y page 156) activated: One or two segments in the set speed range
light up.
DISTRONIC PLUS detects a vehicle in front:
The segments between the speed of the vehi-
cle in front and the stored speed light up.
