Recirculated air mode In recirculated air mode air is sucked
out of the interior of the vehicle
and then fed back into the interior.Recirculated air mode prevents polluted air outside the vehicle from getting into the vehicle, for example when driving through a tunnel or when standing in a traffic jam. Switching recirculated air mode on – Press the button

- the warning light lights up
in the button.
Switching recirculated air mode off – Press again the button - the warning light in the button goes out.The button cannot be pressed if the control dial is in the position
 or close
to this position.
WARNING
You should not leave recirculated air mode on over a longer period of time, as “stale” air may result in fatigue in the driver and occupants, divert your attention and also cause the windows to mist up. The risk of having an acci-
dent increases. Switch recirculated air mode off as soon as the windows begin misting up.Using the air conditioning system economicallyThe compressor on the air co
nditioning system uses po
wer from the engine when
in cooling mode which will effect the fuel consumption. It recommended to open the windows or the doors of a vehicle for which the inte- rior has been strongly heated through the ef
fect of direct sunlight in order to allow
the heated air to escape. The cooling system should not be switched on while travelling when the window is open. The desired interior temperature can also be achieved without switching in the cooling system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.

Climatronic* (automatic air conditioning)Description The Climatronic system is a combin
ation of an automatic heating,
fresh air and cooling system which provides optimal comfort for the occupants of the car.The Climatronic maintains a constant temp
erature fully automatically, once it has
been set. This is achiev
ed by automatically varying the temperature of the
outflowing air, the blower stages and the ai
r distribution. The system also takes into
account bright sunlight which eliminates
the need to alter the settings manually.
The
automatic mode
⇒page 90 ensures maximum wellbeing of the occupants at
all times of the year. Description of Climatronic system The cooling operates only if the following conditions are met:•
engine running,
•
outside temperature above +5 °C,
•
the button is
not
pressed.
If the cooling system is switched on, the temperature and air humidity drops in the vehicle. The wellbeing of the occupants of
the car is enhanced as a result of this
particularly at high outs
ide temperatures and a high air humidity. The system
prevents the windows misting up during the cold season of the year. The heating effect is dependent upon th
e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature. It is possible to briefly activate recirc
ulated air mode in order to enhance the
cooling effect
⇒
.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to ensure that the heating and cooling systems operate properly. The AC compressor is switched off at a hi
gh coolant temperature in order to provide
cooling at a high load of the engine.
After switching on the cooling

and not an indication of a leak! If you make a change before switching off
the ignition, which differs from the auto-
matic mode, the changed functions remain
stored. Only the function “circulating
air” is erased 20 minutes after switching off the ignition. Recommended setting for all periods of the year:•
Set the temperature to 22 °C (72 °F).

WARNING
•
For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin
g. Please familiarize yourself about
how to correctly operate th
e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.•
You should not leave recirculated air mode on over a longer period of
time, as “stale” air may result in fatigue in the driver and occupants, divert your attention and also cause the windows to mist up. The risk of having an accident increases. Switch recirculated air mode off as soon as the windows begin misting up.
Note
•
If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of
deposits. Switch the cooling system on
at least once a month for approximately 5 mi
nutes at the highest blower stage - also
during the cold season of the year - in
order to remove such odours. Also open a
window for a short time.

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 r
unning and thus getting damaged.
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 steerin
g wheel - risk of accident!
•
Do not withdraw the ignition key from the lock until the vehicle has come
to a stop. The steering lock can en
gage 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 start the engine
or switch on electrical
equipment (e.g. power windows) - risk of accident or injury!Starting the engineGeneral You can only start the engine only using an original ignition key.•
Place the gearshift lever into neutral an
d put on the handbrake firmly before
starting the engine.•
The clutch pedal should be fully depr
essed when starting the engine - the
starter then only has to crank the engine.

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 oper
ated 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 wi
th an exhaust gas catalyti
c converter 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 vehi
cle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the pollutant emissions are lower.

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 swit

.
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 fo
r a lengthy period 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 160, “Working in the engine compartment”.
ShiftingShift into reverse only when the vehicle is
stationary. Depress the clutch pedal and
hold it fully depressed. Wa
it a moment before engaging reverse gear in order to
avoid any shift noises. The reversing lights will come on once reverse gear is engaged, provided the igni- tion is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•
One should not lay the hand on the shift lever while driving the vehicle. The
pressure of the hand will be transferred to
the gearshift forks in the gearbox. This
can, over a period of time, lead to
early wear of the gearshift forks.
•
Depress the clutch pedal fully when chan
ging gears, in order to avoid unneces-
sary wear and damage.

Range of sensors The clearance warning begins at a distance of about 160 cm from the obstacle (area ⇒page 97, fig. 108
). The interval between the warning signals becomes shorter
as the clearance is reduced. A continuous tone
sounds from a distance of approx. 30 cm (area ) - danger
area.
You should not reverse any further after this signal sounds!
Activating The parking aid is activated automatically when
reverse gear
is engaged and the
ignition is turned on. This is confir
med by a brief acknowledgement signal.
Deactivating The parking aid is deactivated by removing the reverse gear.
WARNING
•
The parking aid is not a substitute fo
r the driver paying proper attention
and it is always the driver's responsibility to take care when parking the vehicle or carrying ou
t similar manoeuvres.
•
You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., behind your vehicle. Such an obstacle might not be within the range detected by the sensors.
Note
•
The parking aid does not operate if you
are towing a trailer (applies to models
which feature a factory-fitted towing device*).•
If a warning signal sounds for about 3 seconds after switching the ignition on
and engaging reverse gear, and there is no ob
stacle close to your vehicle, this indi-
cates a system fault. 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.
Cruise control system (CCS)*IntroductionThe 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 control 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.

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The ESP aids you maintain control of your vehicle in situations in borderline driving situations such as when negotiating a curve too fast. The risk of skidding is reduced and your vehicle thus offers greater driving stability depending on the conditions of the road surface. This occurs at all speeds. The following systems are integrated into the electronic stability programme:•
Electronic Differential Lock (EDL),
•
Traction control system (TCS),
•
Antilock brake system (ABS),
•
Brake Assist.
Operating principle The ESP switches on automatically when the engine is started and then conducts a self-test. The ESP control unit processes data from the individual systems. It also processes additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin
g pressure and the steering angle.
The direction which the driver wishes to ta
ke is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual behaviour of the vehicle. If differences exis
t, such as the vehicle beginning to skid,
the ESP will automatically brake the appropriate wheel. The car is stabilised again by the forces which take effect when the wheel is braked. Intervention into the brake system takes place primarily on the outer front wheel of a vehicle which tends to oversteer (tendency for the rear of the vehicle to break away) while occurs this is on the inner re
ar wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied by noises. The ESP operates in combination with the ABS
⇒page 135, “Antilock brake system
(ABS)*”. If there is a fault in the ABS system, the ESP also does not operate. The ESP warning light
⇒page 33 lights up in the instrument cluster when there is a
fault on the ESP. Switching off You can switch the ESP off and on again
as you wish, by pressing the button
⇒ fig. 139
. The ESP warning light
⇒page 33 lights up in the instrument cluster
when the ESP is switched off. The ESP should normally always be switched
on. It may be good practice in certain
exceptional cases, such as when you wish
to have wheel slip, to switch off the
system. Examples:

•
when driving with snow chains
•
when driving in deep snow or on a loose surface
•
when it is necessary to rock a vehicle when it has become stuck.
then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the vehicle. Even if a vehicle fitted with ESP you should still always adapt your style of driving to the condition of the
road surface and the traffic situation.
This particularly applies when driving on slippery and wet roads. The increased safety offered must not tempt you to take greater risks than other- wise - risk of an accident!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the ESP. Differing rolling
circumferences of the tyres can lead to an
undesirable reduction in the engine output.•
Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the ESP
⇒page 179,
“Accessories, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock pr
events an individual wheel from
slipping.Vehicles fitted with ABS*
can be equipped with electron
ic differential lock (EDL).
General The EDL makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditio
ns of the road surface are unfavourable.
Operating principle The EDL is activated automatically, that is
without any action on the part of the
driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should only
one
drive wheel begin spinning on a slippery surface there will be an
appreciable difference in the speed of the driven wheels. The EDL function brakes the slipping wheel and the differential transmits a greater driving force to the other driven wheel. This control proces
s is also accompanied by noises.
Overheating of the brakes The EDL switches off
automatically if unusually severe
stresses exist in order to
avoid excessive heat generation in the
disc brake on the wheel which is being
braked. The vehicle can continue to be driv
en and has the same characteristics as a
vehicle not fitted with EDL. The EDL switches on again
automatically as soon as the brake has cooled down.
WARNING
•
Carefully depress the accelerator when accelerating on uniformly slip-
pery road surfaces, such as ice and sn
ow. The driven wheels might still spin
despite the EDL and affect the stability
of the vehicle - risk of an accident!
•
You should always adapt your style of driving to the condition of road
surface and to the traffic situation even
when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•
If the ABS warning light comes on, this ma
y also indicate a fault in the EDL.
Please have the vehicle inspected as soon
as possible by a specialist garage.
•

nation of tyres and wheels) can in
