Heating and air conditioning system93
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Using the air conditioning system economically
The compressor on the air conditioning system uses power from the engine when
in cooling mode which will effect the fuel consumption.
It recommended to open the windows or th e 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.
Operational problems
If the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be:
•The fuse of the air conditioning system is defective ⇒page 220. Check the fuse,
replace it if necessary.
•The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot.
If you are not able to rectify the operat ional problem yourself, or if the cooling
capacity decreases, switch the cooling sy stem off. Contact a specialist garage.
Climatronic* (automatic air conditioning)
Description
The Climatronic system is a combination of an automatic heating, fresh air and
cooling system which provides optimal comfort for the occupants of the car.
The Climatronic maintains a constant temper ature fully automatically, once it has
been set. This is achieved by automa tically varying the temperature of the
outflowing air, the blower stages and the air distribution. It is not necessary to
manually alter the settings. The automatic mode ⇒ page 95 ensures maximum
wellbeing of the occupants at all times of the year.
Description of Climatronic system
The Climatronic can only operate if the following conditions are met:
•engine running,
•outside temperature above +5 °C,
•the button is not pressed.
If the Climatronic 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 outside temperatur es and a high air humidity. The system
prevents the windows misting up during the cold season of the year.
It is possible to briefly activate recirc ulated air mode in order to enhance the
cooling effect ⇒.
The heating effect is dependent upon th e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
Puddle of water below car
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!
Switching over between degrees Celsius and degrees Fahrenheit
First of all press and hold the button ⇒page 94, fig. 109 and then press the
button . The temperature measur ing unit appears in the display.ECON

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 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 215.
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 217.
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 it s normal operating 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.
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 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 220.
•If the engine does not start, contact th e 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.

Starting-off and Driving
102
You should not switch on any major elec trical 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 220.
•If the engine does not start, contact th e nearest specialist garage to obtain
professional assistance.
Starting the engine after 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 the engine off
– Turn the ignition key into position ⇒page 100, fig. 114 .
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 minut es. This prevents any accumulation of heat
when the engine is switched off.
Note
•The radiator fan may continue running for 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 185, “Working in the engine compartment”.

Driving and the Environment165
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Avoiding full throttle
Driving more slowly means saving fuel.
Sensitive use of the accelerator will not only significantly reduce fuel consumption
but also positively influence environmental pollution and wear of your vehicle.
You should avoid fully exploiting the top speed of your vehicle wherever possible.
Fuel consumption, pollutant emissions and vehicle noises increase disproportion-
ally at high speeds.
The ⇒fig. 167 shows the ratio of fuel consumptio n to the speed of your vehicle.
You will cut your fuel consumption by half if you only make use three-quarters of
the possible top speed of your vehicle.
Reducing idling
Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at a level
crossing or at traffic lights with a length y red phase. Even after just 30 - 40 seconds
you will have saved more fuel than that is needed when you start the engine up
again.
If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant em issions, though, are particularly high in the warming-up phase. This is why you should drive off right after starting the
engine. Do avoid high engine re
volutions at this time, however.
Regular servicing
A poorly tuned engine consumes an unnecessarily high amount of
fuel.
Having your vehicle serviced regularly at a specialist garge enables you to satisfy
one of the requirements for economical motoring even before you set off on your
journey. Keeping your vehicle properly serviced not only has a positive effect on the
safety of your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fu el consumption which is 10% higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refueling. Oil consumption is dependent to a consid-
erable extent on the load and speed of the engine. Oil consumption could be as
high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine ha s a higher oil consumption at first, and
reaches its lowest level only after a certain running in time. It is therefore not
possible to correctly assess the oil cons umption of a new vehicle until after you
have driven about 5 000 km.
For the sake of the environment
•You can achieve additional improvements in your fuel economy by using high-
lubricity oils.
•Check the ground below your car at regula r intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garge if you find any
stains caused by oil or other fluids on the floor.

should be attached to folding arms. Adjust the mirrors so that they provide you with
an adequate field of view to the rear.
Headlights
Before starting off with a hitched trailer, also check the setting of the headlights.
Alter the setting as necessary with the aid of the headlight beam adjuster
⇒ page 48.
Detachable ball head
The ball rod is detachable on vehicles wh ich feature a factory-fitted towing device.
It is stowed together with separate fitting instructions in the spare wheel well in the
luggage compartment of the vehicle.
Further information on the towing device ⇒page 171.
Note
•We recommend that you also have yo ur vehicle inspected between service
intervals if you tow a trailer frequently.
•The handbrake on the towing vehicle must be put on when coupling and
decoupling the trailer.
Driving Tips
Particular caution is required when towing a trailer.
– Do not, as far as possible, drive with your vehicle unladen and the
trailer laden.
– Do not make full use of the legal maximum speeds. This applies in
particular to downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temper ature gauge if the outside temper-
ature is high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer
is laden. Maintain a particularly low speed if you cannot avoid driving with this
combination.
Driving speed
Do not drive faster than 80 km/h for safety reasons. This also applies for countries
in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with
increasing speed means that the legally allowed speed should not be used when
there are unfavourable road, weather or wind conditions, particularly near accident
black spots.
You must always reduce your speed immedi ately as soon as you detect even just
the slightest swaying of the trailer. On no account attempt to stop the trailer from
“swaying” by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting from
the trailer wheels locking. Shift down gears in good time before negotiating a down-
hill section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a
lengthy slope in a low gear at a high engi ne speed when the outside temperature is
very high ⇒page 12.
If the needle of the coolant temperature gauge moves into the right-hand area or
even the red area of the scale, reduce yo ur speed immediately. Stop and switch off
the engine if the warning light
 in the instrument cluste r begins flashing. Wait a
few minutes and check the level of coolant in the coolant expansion bottle
⇒ page 190, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 26, “Coolant temperature, Coolant
quantity ”.
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear
and increasing the engine speed is not possible since the fan speed is independent

– After this, once again withdraw the dipstick and read off the oil level ⇒page 187, fig. 175 .
Oil level within range
– You must not top up the oil.
Oil level within range
–You may top up the oil. It is possible that the oil level may then be
within range after doing this.
Oil level within range
–You must top up the oil ⇒page 188. It is sufficient, once this is done,
to keep the oil level is within range .
It is normal for the engine to consume oil. The oil cons umption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. The oil consumpt ion may be slightly higher than this
during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range if the engine has been
operating at high loads, for example during a lengthy motorway trip during the
summer months, towing a trailer or negotiating a high mountain pass, but not
above this .
The warning light in the instrument cluster will indicate whether the oil level is too
low ⇒page 27, “Engine oil ”. In this case, check the oil level as soon as possible.
Top up with an approp riate quantity of oil.
WARNING
Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.
Caution
•The oil level must on no account ex tend beyond the range . Danger of
damaging the catalytic converter.
•Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe engine
damage.
Replenishing engine oil
– Inspect the oil level ⇒page 187.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 186,
“Engine oil specifications”.
– Inspect the oil level ⇒page 187.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING
•Avoid dripping oil onto hot parts of the engine when topping up will oil -
a risk of fire!
•Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.
For the sake of the environment
The oil level must on no account be above the range ⇒page 187, fig. 175. Oil
will otherwise be drawn in through the cr ankcase ventilation and may pass through
the exhaust system to atmosphere. The oi l may combust in the catalytic converter
and damage it.

Caution
•Other coolant additives may cause operational problems which, in partic-
ular, involves significantly reducing the anticorrosion effect.
•Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th is, result in major engine damage.
Inspecting the coolant level
The coolant expansion bottle is located in the engine compartment on
the left.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 185.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 176 .
The coolant level when the engine is cold must lie between the “MIN”
and “MAX” markings. The level may also rise slightly above the “MAX”
marking when the engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light
in the instrument cluster  ⇒ page 22. We nevertheless recommend inspecting
the coolant level directly at th e reservoir from time to time. Loss of coolant
A loss of coolant is first and foremost an
indication of a leak in the system. You
should not merely top up the coolant in the reservoir. It is also important to have
the cooling system inspected without delay by a specialist garage.
Losses can only occur through the pressure relief in the cap of the coolant expan-
sion bottle which is completely free of leaks if the coolant boils as a result of over-
heating and is forced out of the cooling system.
WARNING
Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as soon as possible if the source of over-
heating itself cannot be determined and removed, since there may be grave
damage to the engine.
Replenishing the coolant
– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir ⇒fig. 176 and unscrew the cap carefully by turning it to the left
⇒ .
– Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with one
specific specification ⇒page 189, “Coolant”. Do not use an alternative additive if
the coolant additive G12 PLUS is not available in exceptional cases. Just top up the

Caution
•You must only disconnect the battery if the ignition is switched off, otherwise
the electrical system (electronic components) of the vehicle may be damaged.
When disconnecting the battery from the electrical system of the vehicle, first
disconnect the negati ve terminal (-) of the battery. Then disconnect the positive
terminal (+).
•When reconnecting the battery, first connec t the positive terminal (+) and only
then the negative terminal (-) of the battery. You must on no account connect the
cables wrongly - risk of a cable fire!
•Ensure that battery acid does not come into contact with the vehicle body
otherwise damage could occur to the paintwork.
•Do not place the battery in direct dayl ight in order to protect the battery
housing from the effects of ultra-violet light.
For the sake of the environment
A removed battery is a special type of waste which is harmful to the environment -
contact your specialist garage regarding disposing of the battery.
Note
Please also refer to the guidelines ⇒page 196, “Disconnecting and reconnecting
the battery”, also after connecting the battery.
Battery with a charge level indicator, the so-called magic eye
There is a so-called magic eye ⇒fig. 179 located on the top of the battery. The
“magic eye” changes its colour in line with the charge state of and electrolyte level
in the battery.
Air bubbles can influence the colour of the “magic eye”. For this reason carefully
knock on the “magic eye” before carrying out the check.
•Green colour - the battery is adequately charged
•Dark colour - the battery has to be charged
•Colourless or yellow colour. Have the battery checked by a specialist garage
Batteries, which are more than 5 years old, must be replaced. We recommend you
have the electrolyte level inspected and adjusted to the correct level or the battery
replaced if necessary by a specialist garage.
Caution
If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge because certain electrical comp onents consume electricity (e.g. control
units) also in idle state. You can prevent the discharging of the battery by discon-
necting the negative terminal or charging the battery constantly with a very low
charging current. Please also refer to the notes when working on the battery
⇒ page 193, “Working on the battery”.
