Air conditioning
Air conditioning 2C-Climatronic
Description
The air conditioner is designed to automatically keep the
passenger compartment at the temperature you find most
comfortable at all times of the year. Recommended settings:
– Set the temperature to 22 °C (71 °F).
– Press the AUTO
⇒ Fig. 140 button.
The following setting quickly provides a comfortable temperature inside the
vehicle. We therefore recommend you do not modify the setting unless you
find this temperature uncomfortable or where circumstances require as
such.
The air conditioner provides heating and ventilation and also cools and de-
humidifies the air inside the vehicle.
The air conditioner is fully automatic and will constantly maintain the tem-
perature which has been set. To achieve this, the temperature of the air sup-
plied to the interior, the blower speed (volume of air delivery) and the air
distribution are regulated automatically. The system also takes solar radia-
tion into account and, therefore, no subsequent manual readjustments are
required. Therefore, automatic mode ⇒ page 166 should be used for the
comfort of all the passengers in virtually all conditions throughout the year.
Please note the following points: The humidity of the air is automatically reduced when the system cools the
interior of the vehicle. This helps to prevent condensation on the windows.
If the humidity and temperature outside the vehicle are high,
condensation
can drip off the evaporator in the air cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak.
If the outside temperature is low, the blower normally only switches to a
higher speed once the coolant has warmed up sufficiently (this does not ap-
ply to the defrost setting).
In order to achieve maximum engine power, the air conditioner compressor
is temporarily switched off when pulling away from standstill with full throt-
tle.
The compressor also switches off if the coolant temperature is excessively
high to ensure adequate engine cooling under extreme loads.
Pollution filter
The pollution filter (a combined particulate filter and activated charcoal fil-
ter) serves as a barrier against impurities in the outside air, including dust
and pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
element must be replaced at the intervals specified in the Service Plan.
If the vehicle is driven in areas with a high level of air pollution and the filter
is no longer fully effective, it may be necessary to change the filter element
more frequently. 

CAUTION
● If you suspect that the air conditioner system is damaged, switch over to
ECON mode to prevent further damage and have the system checked by a
specialised workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. For this reason, please contact a specialised workshop if the system
is not working properly.
Note
● Keep the air intake slots in front of the windscreen clear of snow, ice and
leaves to ensure unimpaired heating and cooling and to prevent the win-
dows misting over.
● The air from the outlets flows through the passenger compartment and
out through the slots below the rear window. Therefore, do not cover these
slots with items of clothing or other objects.
● The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the vehicle has heated up after
standing in the sun for some time, the air inside can be cooled more quickly
by opening the windows briefly. 

to +29 °C (86 °F).
– Press the AUTO
⇒ 
Fig. 140 button.
The automatic mode maintains a constant temperature inside the vehicle
and dehumidifies the air. Air temperature, air delivery and air distribution
are regulated automatically to reach the desired interior temperature as
quickly as possible, and then to maintain this temperature. The system au-
tomatically compensates for any variations in the outside temperature and
for the effect of direct sunlight.
The automatic temperature regulation only operates at temperature settings
between +18 °C and +29 °C. If a temperature below +18 °C is selected, LO
appears on the display. If a temperature is selected which is higher than +29 °C, the display will show
HI. In the maximum and minimum settings,
the climate control operates continuously with maximum cooling or heating
output and the temperature is not regulated automatically. The temperature
is not regulated.
Note
By keeping the AUTO button on the driver side pressed for several seconds,
the temperature of the passenger side can be set to the temperature of the
driver side or vice versa. The display indicates the new temperature value. 

In this setting, the air in the vehicle is constantly recirculated. We recom-
mend using the air recirculation mode in the following circumstances: ●
When driving through a tunnel or in traffic congestions, to prevent ex-
haust gas entering the interior of the vehicle.
WARNING
Do not drive for too long with the air recirculation mode enabled because,
if the compressor is disconnected, the windscreen may mist up because
no fresh air is entering the interior of the vehicle, with the subsequent
risk of accidents.

ECON Mode (economy) ECON
ECON mode helps save fuel.
– To activate, press the ECON
button ⇒ Fig. 140.
– To deactivate, press the ECON
button again or select the AUTObutton.
Air cooling is disconnected in ECON mode. The heating and the blower are
adjusted automatically. “ECON” stands for “Economy”. Disconnecting air
cooling (compressor) reduces fuel consumption.
Please note that the interior temperature must not be lower than the outside
temperature in ECON mode. The blower does not cool or dehumidify the air
in the interior. The windows could therefore mist up.
In diesel vehicles, the auxiliary heater is switched off in ECON mode to save
fuel. 

If the air recirculation mode is on when you switch off the engine, the air
conditioner will automatically switch to fresh air ventilation. 
Auxiliary heater*
Diesel vehicles are fitted with an auxiliary heater 1)
to raise the temperature
of the interior as quickly as possible. At outdoor temperatures below +5 °C
and with the engine running, the supplementary heating will switch on and
off automatically depending on the temperature of the coolant.
In order to save fuel, the auxiliary heater can be can be switched off by brief-
ly pressing the 

Driving
Position 1
The ignition key is inserted in this position. To
engage the steering wheel
lock, take out the key and turn the wheel until you hear the pin engage. You
should always engage the steering lock when you leave the vehicle. This
will help to deter thefts ⇒ 
.
Switching on the ignition/pre-heating glow plugs 2
If the key is difficult to turn in the lock, move the steering wheel (to take the
load off the steering lock mechanism) until the key turns freely. In the case
of vehicles with a diesel engine, the key is turned to this position to preheat
the glow plugs.
Starting the engine 3
The engine is started in this position. Electrical components with a high
power consumption are switched off temporarily.
After the engine has started, the ignition key returns to position 2
by itself.
The ignition key has to be turned back to position 1
before re-starting the
engine. The starter inhibitor in the ignition lock prevents the starter motor
from engaging when the engine is running, as this could cause damage.
Switching off the ignition 1
Turn the ignition key to this position.
WARNING
● Never remove the ignition key until the vehicle is stationary! Other-
wise the steering lock could engage suddenly, which could cause an acci-
dent.
● Always take the key with you when leaving the vehicle, even if you
only intend to be gone for a short time. This is particularly important if
there are children in the vehicle, as they might otherwise be able to start
the engine or use power-operated equipment (e.g. the electric windows),
which could cause injuries.
Note
● If the battery has been disconnected and then reconnected, it will be
necessary to leave the key in position 2
for about 5 seconds before start-
ing the engine.
● Vehicles with automatic gearbox: After switching off the ignition, you
can only remove the ignition key if the selector lever is in position “P” (park-
ing lock). The selector lever is locked after the ignition key has been re-
moved. 

When starting a very cold engine, it may be a little noisy for the first few sec-
onds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If the engine fails to start straight away, stop after 10 seconds and try again
after about half a minute. Glow plug system*
To assist starting at low temperatures,
diesel engines are equipped with a
glow plug preheating system. The preheating time depends on the coolant
temperature and the outside temperature. Start the engine as soon as the
glow plug indicator light  goes out.
When the engine is warm or at outside temperatures above +8 °C the glow
plug indicator lamp will only light up for about one second. This means that
the engine can be started immediately.
If the engine will not start...

WARNING
Never run the engine in confined spaces, as the exhaust gases are poi-
sonous.
CAUTION
Avoid high engine speeds, full throttle and extreme load conditions until
the engine has reached its normal operating temperature, otherwise this
can damage the engine.
For the sake of the environment
Do not warm up the engine by running the engine with the vehicle station-
ary. Start immediately. This will help avoid unnecessary exhaust emissions. 
Stopping the engine

WARNING
Please remember that the accident risk always increases if you drive too
fast, especially in corners or on a slippery road, or if you follow too close
behind the vehicle in front of you. An increased accident risk cannot be
compensated even by the brake assist system. Risk of accident.

Electronic differential lock (EDL)
The electronic differential lock prevents the loss of traction
caused if one wheel starts spinning. General notes
The electronic differential lock (EDL) helps the vehicle to start moving, ac-
celerate and climb a gradient in slippery conditions where this may other-
wise be difficult or even impossible.
How it works
The EDL works automatically, without the driver's involvement. With the aid
of the ABS sensors, the system monitors the rotational speed of the drive
wheels ⇒ page 197. If a considerable difference in revs is detected (approx.
100 rpm) in the speed of the drive wheels, e.g. when only one part of the
surface supporting the wheels is slippery, the system applies the brake to
slow down the skidding wheel so that more of the power is directed to the
other wheels. The systems works up to a speed of approx. 80 km/h. The
system will make noise while it is working.
Starting the vehicle
If one wheel has less grip and starts spinning (for instance, if one of the
drive wheels is on ice), keep pressing the accelerator gradually until the ve-
hicle starts moving. Overheating of the brakes
To prevent the brake disk of the braked wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. In this case, the vehi-
cle will continue to run and will have the same running properties as those
of another without EDL.
The EDL will switch on again automatically when the brake has cooled
down.
WARNING
● When accelerating on a uniformly slippery surface (for instance all
four wheels on ice or snow), press the accelerator gradually and careful-
ly. Despite EDL, the drive wheels may otherwise start to spin. This could
impair the vehicle's stability. Risk of accident.
● Even with EDL, you should always adjust your speed to suit the road
and traffic conditions. Do not let the extra safety features tempt you into
taking any risks when driving. Failure to do so could result in an accident.
Note
If the ABS warning lamp lights up, this can also mean there is a fault in the
EDL. Take the vehicle to a specialised workshop as soon as possible. 
Traction control system (ASR)
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating. General notes
The traction control system (ASR) is one of the functions incorporated in the
Electronic Stability Control (ESC) 

203
Driving and the environment
WARNING (Continued)
● On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed
and change down into a lower gear or range (depending on the type of
transmission). This makes use of engine braking and relieves the brakes.
● Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
● Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
● If the brake fluid loses its viscosity and is subjected to heavy use, va-
pour bubbles can form in the brake system. This reduces the efficiency of
the brakes.
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat. Before purchasing accessories
please observe the relevant instructions ⇒ page 230, Technical modifi-
cations.
● If a brake system circuit fails, the braking distance will be increased
considerably. Contact a specialised workshop immediately and avoid un-
necessary journeys.

Exhaust gas purification system Catalytic converter*
To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages
the catalytic converter.
– Do not let the fuel get too low in the tank. –
For engine oil changes, do not replenish with too much engine
oil ⇒ page 239.
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 295.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp
will light up when any of the described symptoms occur ⇒ page 68. If this
happens, unburnt fuel can enter the exhaust system and escape into the en-
vironment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! Risk of fire!
● Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.
● Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust sys-
tem. These materials could catch fire when the vehicle is being driven.
CAUTION
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel. 

Driving and the environment
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at lev-
el crossings or at traffic lights with a long red phase. The fuel saved after
only 30 - 40 seconds is greater than the amount of fuel needed to restart
the engine.
The engine takes a long time to warm up when it is idling. Mechanical wear
and pollutant emissions are also especially high during this initial warm-up
phase. It is therefore best to drive off immediately after starting the engine.
Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey,
you will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting exhaust gases, the
engine and the exhaust gas filtration systems should reach the optimum
operating temperature.
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres (2.5 miles). This is why we recommend
avoiding short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If
the tyre pressure is just one bar too low, fuel consumption can increase by
as much as 5%. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.Do not use
winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Given that every kilo of extra weight will increase the fuel consumption, it is
advisable to always check the luggage compartment to make sure that no
unnecessary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h (60-75 mph) your vehicle
will use about 12% more fuel as a result of the extra wind resistance caused
by the roof rack even when it is not in use.
Save electricity
The engine activates the alternator, which produces electricity. With the
need for electricity, fuel consumption is also increased. Because of this, al-
ways turn off electrical components when you do not need them. Examples
of components that use a lot of electricity are: the fan at high speeds, the
rear window heating or the seat heaters*.
Note
● If you vehicle has Start-Stop, it is not recommended to switch this func-
tion off.
● It is recommended to close the windows when driving at more than
60 km/h (40 mph)
● Do not drive with your foot resting on the clutch pedal, as the pressure
can make the plate spin, more fuel will be used and it can burn the clutch
plate lining, causing a serious fault.
● Do not hold the vehicle on a hill with the clutch, use the foot brake or
hand brake, using the latter to start. The fuel consumption will be lower and
you will prevent the clutch plate from being damaged.
● On descents, use the engine brake, changing to the gear that is more
suitable for the slope. The fuel consumption will be lower and the brakes
will not suffer. 
