Auxiliary heating system (auxiliary heating and
ventilation)*
Description
The auxiliary heating (auxiliary heating and ventilation) heats or
supplies the interior of the vehicl e with fresh air independent of the
engine.
Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) f unctions in connection with the heater or
with the Climatic or Climatronic.
It can be used when stationa ry, when engine is switched off for preheating of the
vehicle as well as while driving (e.g. during the heating phase of the engine).
The auxiliary heating (auxiliary heating) warms up the coolant during the combus-
tion of fuel from the vehicle tank. The cool ant warms up the air, which (if the blower
speed is not set to zero) flows into the occupant compartment.
6)
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching on the blower, if the blower speed is not set to zero, whereby the interior
temperature is effectively decreased (e.g. with a vehicle parked in the sun).
Using the system
So that the auxiliary heating (auxiliary heating and ventilation) func-
tions according to your expectations, it is necessary to carry out the
basic setting before its programming.
Basic setting
– In the information display, select from the menu Main menu the
Menu Setup (settings) ⇒ page 19, fig. 11 .

WARNING
•The auxiliary heating must never be operated in closed rooms - risk of
poisoning!
•The auxiliary heating must not be running during refueling - risk of fire.
•The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. Therefore do not place the vehicle, if you wish to operate the
auxiliary heating, in such a way that the exhaust gases of the auxiliary
heating can come easily into contact with inflammable materials (e.g. dry
grass) or easily inflammable su bstances (e.g. fuel run out).
Note
•If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
Therefore the auxiliary heating should not be operated, if there is very little fuel in
the tank.
•The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
•If the auxiliary heat ing and ventilation is running, the vehicle battery discharges.
If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometers in order to recharge the
vehicle battery.
•The auxiliary heating only sw itches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.
•At low outside temperatures, this can resu lt in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating
problem.
•After switching off the auxiliary heating, the coolant pump runs for a short
period.
•The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicate s a low loading state.
•The auxiliary heating (auxiliary heating) switches on, if in the information
display: Please refuel! is indicated or was indicated before switching off the igni-
tion.
•When driving, the auxiliary heating can only be switched on, if the exterior
temperature is lower than 5 °C.
•The air inlet in front of the windscreen mu st be free of ice, snow or leaves in
order to ensure that the auxiliary heating operates properly.
•So that the warm air can flow into the vehicle interior after switching on the
auxiliary heating (auxiliary heating), the control dial ⇒page 100, fig. 119 must
be turned up to the stop to the right when heating. With Climatic and Climatronic,
you can maintain the temperature norma lly selected by you (we recommend 22
°C). It is recommended to put the air flow in the position
. For heating and
climatic put the blower switch ⇒page 100, fig. 119 if necessary ⇒page 104,
fig. 122 in the position 2.
•On vehicles with DPF (die sel particle filter) the warm coolant heats up the
engine.

Ignition lock
Petrol engines
- ignition switched off, engine off, the steering can be locked.
- ignition switched on
- start engine
Diesel engines - interruption of fuel supply, ignition switched off, engine off, the steering can
be locked.
- heating glow plugs on, ignition switched on
•You should not switch on any major elec trical components during the heating
period otherwise the vehicle batter y will be drained unnecessarily.
- start engine
Applies to all models:
Position
To lock the steering , with the ignition key withdrawn, turn the steering wheel until
the steering locking pin is heard to engage. You should always lock the steering as
a general rule if you leave your vehicle. This acts as a deterrent against possible theft
of your vehicle ⇒.
Position Move the steering wheel back and forward
a little if the ignition key cannot, or
cannot easily be turned into this position, in order to release the steering lock.
Position
The engine is started in this position. At the same time switched on low beam or
main beam or other electrical compon ents with major power consumption are
briefly switched off. The ignition key moves back into position when one
releases the key.
The ignition key must be turned back into position each time before starting the
engine again. The starter repeat lock in th e ignition lock prevents the starter being
engaged when the engine is ru nning and thus getting damaged.
Ignition key withdrawal lock (automatic gearbox)
You can only withdraw the ignition key after switching off the ignition if the selector
lever is in position P.
WARNING
•When driving, the ignition key must always be in the position (igni-
tion switched on) without the engine running. This position is indicated by
the warning lights coming on. If this is not the case, it could result in unex-
pected locking of the steering wheel - risk of accident!
•Only remove the ignition key from the ignition lock when the vehicle has
come to a standstill (put on the handbrake or select the selector lever posi-
tion P). The steering lock can enga ge immediately - risk of accident!
•Always withdraw the ignition key if you are going to leave the vehicle,
even for a short time. This is particularly important if children are left in the
vehicle. The children might otherwise star t the engine or switch on electrical
equipment (e.g. power windows) - risk of accident or injury!

Starting the engine
General
You can only start the engine only using an original ignition key.
•Place the gearshift lever into neutral (or place the selector lever to the position
P or N in the case of an automatic gearbox) and put on the handbrake firmly before
starting the engine.
•The clutch pedal should be fully depressed when starting the engine which
means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be damage
to the starter.
The engine running noises ma y louder at first be louder for a short time after
starting the cold engine until oil pressure can be built up in the hydraulic valve
clearance compensation. This is quite no rmal and is not an operating problem.
If the engine does not start ...
You can use the battery of anothe r vehicle as a jump-start aid ⇒page 238.
It is only possible to tow-start vehicles fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres ⇒page 242.
WARNING
•Never run the engine in non ventilat ed or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon
monoxide a poisonous gas - hazard! Carbon monoxide can cause uncon-
sciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), if the engine is not
running. If the starter is immediately operated after switching off the engine, the
starter or the engine can be damaged.
•Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper ating temperature - risk of damaging the
engine!
•Vehicles which are fitted with an exhaust gas catalytic conver ter should not be
tow-started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the
pollutant emissions are lower.
Petrol engines
These engines are fitted with a starter system which selects the correct fuel/air
mixture for every external air temperature.
•Do not operate accelerator befo re and when starting engine.
•Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.
•It is possible that the fuse on the electrical fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary ⇒page 243.
•Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator
after the engine has started.
Diesel engines
Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside temper-
ature.
The preglow indicator light
 comes on after the igniti on has been switched on.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.
•You should start the engine immediately after the glow plug warning light 
has gone out.
•The glow plug warning light will come on for about one second if the engine is
at a normal operating temperature or if th e outside temperature is above +5°C. This
means that you can start the engine right away.
•Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.
•It is possible that the fuse on the diesel preglow system is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒page 243.
•Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank has
run completely dry - up to one minute. This is because the fuel system must first of
all be filled while the attempting to start the engine.
Switching off the engine
– The engine can be switched off by turning the ignition key from posi- tion ⇒page 117, fig. 132 into position .
WARNING
•Never switch off the engine before the vehicle is stationary - risk of acci-
dent!
•The brake booster only operates when the engine is running. Greater
physical effort for braking is required when engine is switched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.
Caution
you should not switch the engine off right away at the end of your journey after the
engine has been operated for a lengthy peri od at high loads but should be allowed
it to run at idling speed for about 2 minutes. This prevents any accumulation of heat
when the engine is switched off.
Note
•The radiator fan may continue running fo r a further 10 minutes or so after the
engine and the ignition have been switched off. The coolant fan may, however, also
switch on again after some time if the coolant temperature rises because of an
accumulation of heat in the engine or if the engine is warm and the engine
compartment is additionally heated by strong sunlight.
•This is why particular care is required when carrying out any work in the engine
compartment ⇒page 210, “Working in the engine compartment”.
Shifting (manual gearbox)
Shift into reverse only when the car is stationary. Depress the clutch pedal and hold
it fully depressed. Wait a moment before engaging reverse gear in order to avoid
any shift noises.

Note
•Only the front parking aid operates if you are towing a trailer (applies only to
models which feature a factory-fitted towing device*).
•If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, th is indicates a system fault. The fault is
confirmed additionally when the symbol
 flashes in the button ⇒page 122,
fig. 136 . Have the fault rectified by a specialist workshop.
•The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
•If the parking aid is activated and the se lector lever of the automatic gearbox is
in the position , warning signal indicates interruption (vehicle can no longer
move).
Cruise control system (CCS)*
Introduction
The cruise control system (CCS) maintains a constant speed, more than 30 km/h (20
mph), once it has been set, without you having to depress the accelerator pedal.
This is only possible within the range wh ich is permitted by the power output and
braking power of the engine. The cruise co ntrol system makes it possible - particu-
larly on long journeys - for you to rest your “accelerator foot”.
WARNING
•The cruise control system must not, for safety reasons, be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads or
loose chippings) - risk of accident!
•In order to prevent unintentional use of the cruise control system, always
switch off the system after use.
Note
•Models fitted with a manual gearbox: Al ways depress the clutch pedal if you
switch on the cruise control system when the gearbox is in Neutral. Otherwise the
engine can rev up unintentionally.
•The cruise control system is not able to maintain a constant speed when driving
on steep downhill sections. The weight of the vehicle increases the speed at which
it travels. One should shift down in good time to a lower gear or slow the vehicle
down by applying the foot brake.
•It is not possible on vehicles fitted with an automatic gearbox to switch on the
cruise control system if the sele ctor lever is in the position P, N or R.
Storing a speed
The cruise control system is operated by means of the switch and
rocker button in the left lever of the multi-functional switch.
– Press the switch ⇒fig. 138 into the position ON.
– After the desired speed has been reached, press the rocker button into the SET position.

Automatic gearbox
6-speed automatic gearbox*
Introduction
Your car is equipped with an electronic ally controlled 6-speed automatic gearbox.
Shifting up and also down through the gears is performed automatically.
At the same time this is a conventional automatic gearbox. The maximum speed is
reached in the 5th gear. The 6th gear se rves as an economic driving programme,
which is intended to reduce the fuel consumption.
Information for driving with an automatic gearbox
Shifting up and down through the gears is performed automatically.
You can also, however, switch the gearbox over into the Tiptronic mode.
This mode makes it possible for you to also shift gears manually
⇒ page 129.
Starting-off and Driving
– Depress the brake pedal and hold it depressed.
– Press the Shiftlock button (button in handle of the selector lever),
move the selector lever into the desired position, e.g. D ⇒ page 127,
and then release the Shiftlock button.
– Wait a moment until the gearbox has shifted (a slight engagement nudge can be felt).
– Release the brake pedal and depress the accelerator ⇒. Stopping for a short time
– The selector lever position
N does not have to be selected when stop-
ping just for a short time, such as at a cross roads. It is sufficient to hold
the vehicle stationary using the foot brake. The engine can, however,
be allowed just to idle.
Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector
lever to P and then release the Shiftlock button.The engine can only be started when the selector lever is in position P or N
⇒ page 118.
It is sufficient to engage selector lever position P when parking on a flat surface.
When parking on a slope you should first apply the handbrake firmly and then
move the selector lever into position P. This is to ensure that there is no excessive
pressure acting on the lock mechanism and that it is easier to subsequently move
the selector lever out of position P.
If the selector lever position N is selected by accident wh ile driving it is first neces-
sary to release pressure on the accelerato r pedal and wait for idling speed of the
engine to be reached before engaging a drive position in the selector lever.
WARNING
•Do not depress the accelerator when changing the position of the
selector lever if the car is stationary and the engine is running - risk of acci-
dent!
•Never move the selector lever into position R or P when driving - risk of
an accident!

•When the engine is running and the vehicle is stationary, it is necessary
to hold the car with the brake pedal in all the positions of the selector lever
(except P and N) since the power transmission is never completely inter-
rupted, also not when the engine is idling - the vehicle "creeps".
Selector lever positions
The selector lever position you have engaged is shown in the information display
of the instrument cluster with the co rresponding gear symbol highlighted ⇒
fig. 140 . In the positions D and S the gear you have already engaged will be addi-
tionally displayed on the display.
P - Parklock
The driven wheels are locked me chanically in this position.
The Parklock must only be engage d when the vehicle is stationary ⇒.
If you wish to move the select or lever into or out of this position, you must press the
Shiftlock button in the handle of the select or lever and at the same time depress the
brake pedal.
If the battery is used, the selector le ver cannot be moved out of the position P
⇒ page 130.
R - Reverse
Reverse gear must only be engaged when the vehicle is stationary and the engine
idling ⇒ .
The brake pedal must be depressed and at the same time the Shiftlock must be
pressed, if you wish to obtain the selector lever positions R, P or N.
When the ignition is switched on and the selector lever is in position R, the reverse
lights will come on.
N - Neutral
The transmission is in Neutral in this position.
The brake pedal must be depressed (if the le ver is in its position for longer than 2
seconds) in order to move the selector lever out of the position N into the position
D , with the ignition switched on, on a vehicle travelling at less than 5 km/hour or on
a stationary vehicle.
The brake pedal must be depressed (if the le ver is in its position for longer than 2
seconds) in order to move the selector lever out of the position N into the position
R , with the ignition switched on, on a vehicl e travelling at less than 5 km/hour or on
a stationary vehicle.
D - Drive, position for driving forward
When the selector lever is in this position, the forward gears are shifted up and
down automatically in line with engine load, vehicle speed and the dynamic shift
programme.

You must depress the brake pedal ⇒ if you wish to move the selector lever into
position D from N when the vehicle is travelling at less than 5 km/hour or is
stationary.
In certain circumstances (e.g. when driving in mountainous regions or when towing
a trailer) it may be beneficial to select the manual shift programme ⇒page 129 for
a short time in order to adapt the gearbox ratios manually to the driving situations.
S - Position for sporty style of driving
Shifting up later into a higher gear ma kes it possible to fully exploit the power
potential of the engine. The gearbox also th en shifts down at higher engine speeds
as in the position D.
The gearbox does not shift into the 6th gear in the position S, because the
maximum speed is achieved with the 5th gear.
The Shiftlock on the selector lever grip must be pressed when moving the selector
lever out of the position D into the position S.
WARNING
•Never move the selector lever into position R or P when driving - risk of
an accident!
•When the engine is running and the ve hicle is stationary, it is necessary
to hold the car with the brake pedal in all the positions of the selector lever
(except P and N) since the power transmission is never completely inter-
rupted, also not when the engine is idling - the vehicle "creeps".
•You must on no account unintentionally operate the throttle (e.g. by
hand from the engine compartment) if a drive position is engaged when the
car is stationary. The vehicle would ot herwise immediately start off - also
when the handbrake is firmly a pplied - risk of an accident!
•You must move the selector lever into position P and firmly apply the
handbrake first before you or any other person opens the bonnet and starts
working on the engine when it is running - risk of accident! It is also essential
to observe all warnings ⇒page 210, “Working in the engine
compartment”.
Selector lever lock
Automatic selector lever lock 
With the ignition on, the selector lever is locked when it is in the positions P and N .
You must first of all depress the brake pedal in order to move the selector lever out
of this position. The warning light
 ⇒ page 31 lights up in the instrument cluster
as a reminder for the driver when the selector lever is in position P and N:
In addition, the symbol
 for the automatic selector lever lock in the shift gate
lights up.
A time delay element ensures that the selector lever is not blocked when rapidly
switching over the position N (e.g. from R to D). This does, for example, allow one
to seesaw out a stuck vehicle. The selector lever lock will click into place if the lever
is in the N position for more than 2 seconds without the brake pedal being pressed.
The selector lever lock is only active if th e vehicle is stationary or moving at speed
of less than 5 km/hour. The lock is switched off automatically into position N when
the car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the handle of sele ctor lever prevents certain selector lever
positions being engaged inadvertently. The selector lever lock is cancelled when
you press the Shiftlock button.
Keylock - Ignition key withdrawal lock
You can only withdraw the ignition key after switching off the ignition if the selector
lever is in position P. If the ignition key is withdrawn, the selector lever is blocked in
position P .
Kickdown function
The kickdown function provides you with maximum acceleration
power.
Depressing the accelerator pedal allows th e kickdown function to be activated in
the desired driving program. This function has precedence over the driving
programme and serves for maximum accelera tion of the vehicle when exploiting
the maximum power potential of the engi ne without taking into account the

current selector lever position (
D, S or Tiptronic ). The gearbox shifts down to one
or several gears in line with the driving state and the vehicle accelerates. The
gearbox does not shift up into the highes t gear until the engine has reached its
maximum revolutions for this gear range.
WARNING
Please note that using the kickdown fu nction can result in the driven wheels
spinning on a smooth or slippery road surface - risk of skidding!
Dynamic shift programme
The automatic gearbox of your vehicle is controlled electronically. Shifting up and
down through the gears is performed auto matically on the basis of pre-defined
driving programmes.
Adopting a moderate style of driving will cause the gearbox to select the most
economical driving programme. Shifting up into a higher gear as soon as possible
and shifting down as late as possible will have a favourable effect on your fuel
consumption.
Adopting a sporty style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and freq uent changes in speed, exploiting the
top speed of the car or depressing the a ccelerator pedal (kickdown function), will
cause the gearbox to switch over to this style of driving and shift down earlier with
frequent changes in gears in comparison to the moderate style of driving.
Selecting the most appropriate driving programme for the particular style of driving
is a continuous process. Irrespective of this it is, however, possible to switch or shift
down into a dynamic shift programme by depressing the accelerator rapidly. The
gearbox shifts down into a lower gear matc hing the speed of the car and this allows
you to accelerate rapidly (e.g. when ov ertaking) without having to depress the
accelerator pedal fully into the kickdown range. The original programme will be
reactivated to match your particular style of driving once the gearbox has shifted up
again.
When driving in hilly regions, the gears are selected to match uphill and downhill
sections. This avoids the gearbox frequently shifting up and down when negotiating an uphill stretch. When driving downhill, it is possible to shift down into the
Tiptronic position, in order to
exploit the engine brake torque.
Tiptronic
The Tiptronic allows the driver to also shift gears manually.
Switching over to manual shifting
– Push the selector lever to the right out of position D. As soon as the
gearbox has switched over, 6 5 4 3 2 1 appears in the display, with the
gear engaged being highlighted.
