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 Condensation from the evaporator of the air condi- tioning may drip down and form a puddle below the vehicle. This is quite normal and not an indication of a leak!
Recommended setting for al l periods of the year:
•Set the temperature to 22 °C.
•Press the button ⇒fig. 97.
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards ⇒ page 88, fig. 98.
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒fig. 97. The information in the desired temperature measuring unit appears in the display.
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.
•We recommend that you do not smoke in the vehicle when the recirculating air mode is operating since the smoke which is drawn at the evaporator from the inte- rior of the vehicle forms deposits in the ev aporator of the air conditioning system. This produces a permanent odour when th e air conditioning system is operating which can only be eliminated through co nsiderable effort and expense (replace- ment of compressor).
•The used air streams out through the air removal openings in the luggage compartment.

Defrosting windscreen - switching off
– Once again press the button or the button .
The temperature control is controlled automa tically. More air flows out of the air outlet vents 1 and2.
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 button , the symbol appears on the display.
Switching recirculated air mode off
– Once again press the button or the button , the symbol or
the logo is no longer shown on the display.
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
accident increases. Switch recirculated air mode off as soon as the windows begin misting up.
•After 15 minutes of constant recirculated air mode, the symbol flashes on the display of the Climatro nic for 5 minutes. Immediately switch off the recirculated air mode.
Note
If the windscreen mists up, press the button . After the windscreen has been demisted, press the button .
Setting temperature
– You can set the desired interior temperature after switching on the
ignition with the control dial .
You can set the interior temperature be tween +18°C and +29°C. The interior temperature is regulated automatically with in this range. If you select a tempera- ture of less than +18 °C, “LO” is shown on the display. If you select a temperature above +29 °C, “HI” is shown on the displa y. In both limit positions the Climatronic operates at maximum cooling or heating capacity, respectively. The temperature is not controlled in this case.
Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg area) and large differences in temperat ure, for example when getting out of the vehicle, can result in chills in sensitive persons.
Controlling blower
There are a total of seven blower stages available.
The Climatronic system controls the bl ower stages automatically in line
with the interior temperature. You can also, however, adapt the blower
stages manually to suit your particular needs.

place.
WARNING
•You must not adjust the steering wh eel when the vehicle is moving!
•The driver must maintain a distance of at least 25 cm to the steering wheel ⇒fig. 100. Not maintaining this minimum distance will mean that the airbag system will not be able to properly protect you - hazard!
•For s a fe t y re a s ons the le v e r m ust a lwa y s b e fi rm l y pus he d up t o a vo id the steering wheel altering its position unintentionally when driving - risk of accident!
•If you adjust the steering wheel furthe r towards the head, you will reduce the protection offered by the driver airb ag in the event of an accident. Check that the steering wheel is aligned to the chest.
•When driving, hold the steering wheel with both hands firmly on the outer edge in the 9 o'clock and 3 o'clock position. Never hold the steering wheel firmly in the 12 o'clock position or in another way (e.g. in the middle of the steering wheel or at the inner steering wheel edge). In such cases, injuries to the arms, the hands and the head can occur when the driver airbag is deployed.

•Let go of the key as soon as the engine starts otherwise there may be damage to the starter.
The engine running noises may 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 normal 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 202.
It is only possible to tow-start vehicl es fitted with a manual gearbox. The tow- starting distance must not be more than 50 metres ⇒page 205.
WARNING
•Never run the engine in non ventilated 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 catalytic 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 vehicle is standing. Drive off right away. When driving 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 before 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 electric al fuel pump is defect if the engine still does not start. Check the fuse and replace it if necessary ⇒page 207.
•If the engine does not start, 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 ignition has been switched on.
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 the 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 207.

The handbrake warning light lights up when the handbrake is applied, provided the ignition is on.
A warning signal sounds and the following te xt appears in the display* if you have inadvertently driven off with the handbrake applied:
HANDBRAKE ON
The handbrake warning is activated if you drive at a speed of more than 6 km/h for more than 3 seconds.
WARNING
•Please note that the handbrake must be fully released. A handbrake which is only partially released can re sult in the rear brakes overheating which will have a negative effect on th e operation of the brake system - risk of accident! In addition this can result in premature wear of the rear brake pads.
•Never leave children unattended in the vehicle. The children might, for example, release the handbrake or take the vehicle out of gear. The vehicle might then move off - risk of accident!
Caution
After the car has come to a stop, always firs t of all apply the handbrake firmly before then additionally engaging a gear (manua l gearbox) or moving the selector lever into position P (automatic gearbox).
Parking aid*
The parking aid provides a warning of obstacles behind the vehicle.
The audible parking aid determines the distance between the rear bumper and an obstacle located behind the vehicle with th e aid of ultrasound sensors. The sensors are integrated in the rear bumper.

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. 105 into the position ON.
– After the desired speed has been reached, press the rocker button
into the SET- position - the current speed is stored.
After you have released the rocker button out of the position SET-, the speed you have just stored is maintained at a constant speed without having to depress the accelerator.
Yo u c a n increase the speed by depressing the accelerator. Releasing the acceler- ator will cause the speed to drop again to the set speed.
This does not apply, however, if you drive at a speed which is more than 10 km/h higher than the set speed for a period of longer than 5 minutes. The stored speed will be cancelled in the memory. You th en have to re-store the desired speed.
One can reduce the speed in the usual manner. The system is switched off tempo- rarily by actuating the brake or clutch pedal ⇒page 96.
WARNING
First ensure that it is not too high for the traffic conditions which exist at that moment before resuming the stored speed.
Changing a stored speed
You can also change the speed of the vehicle without depressing the
accelerator.
Fa s t er
–You can increase the stored speed without depressing the acceler-
ator, by pressing the rocker button ⇒fig. 105 into the RES+ posi-
tion.
– The speed of the car will increase co ntinuously if you hold the rocker
button pressed in the RES+ position. Once the car has reached the
desired speed, release the rocker butto n. The set speed is then stored
in the memory.
Slower
–You can decrease the stored speed by pressing the rocker button
in the SET- position.
– Holding down the pushbutton pressed in the SET- position will cause
the speed of the vehicle to reduce continuously. Once the car has
reached the desired speed, release the rocker button. The set speed is
then stored in the memory.
– If you release the rocker button when the car is travelling at a speed of
less than 30 km/h, the speed is not stored, the memory is erased. It is
then necessary to again store the sp eed with the rocker button in
the position SET- after an increase in speed of the vehicle to more
than 30 km/hour.

Automatic gearbox
6-speed automatic gearbox*
Introduction
Your car is equipped with an electronically 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 serves 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 100.
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 98,
and then release the Shiftlock button.
– Wait a moment until the gearbox ha s 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 90.
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 while 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 an d the engine is running - risk of acci- dent!
•Never move the selector lever into position R or P when driving - risk of an accident!

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 100 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 makes it possible to fully exploit the power potential of the engine. The gearbox also then 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 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".
•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 applied - 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 174, “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 27 lights up in the instrument cluster as a reminder for the driver when the selector lever is in position P and N:
A time delay element ensures that the sele ctor 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.
Note
For vehicles fitted with manual gearbox, yo u can withdraw the ignition key in each selector lever position after switching off the ignition.
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 engine 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
