Air conditioning
118Cooling system
When the cooling system is switched on, not only the temperature, but also
the air humidity in the vehicle interior is reduced. This improves comfort for
the vehicle occupants and prevents misting of the windows when the outside
air humidity is high.
If the cooling system cannot be switched on this may be due to the following
reasons:•
the engine is not running.
•
The blower is switched off.
•
The outside temperature is lower than approx. +5°C.
•
the cooling system compressor has been temporarily switched off
because the engine coolant temperature is too high.
•
The air conditioner fuse is faulty.
•
Another fault in the vehicle. Have the air conditioner checked by a quali-
fied workshop.
Air recirculation
Air recirculation mode prevents fumes or unpleasant smells
from entering the vehicle.When air recirculation mode is switched on (button ⇒page 117, fig. 89
with warning lamp) strong odours in the outside air do not enter the vehicle
interior, for example when passing through a tunnel or in queuing traffic.
When the outside temperature is low, using air recirculation mode provides
more effective heating by heating air from the vehicle interior instead of cold
air from outside.
When the outside temperature is high, using air recirculation mode provides
more effective cooling by cooling air from the vehicle interior instead of warm
air from outside. For reasons of safety, air recirculation is
not possible when the control for air
distribution is set to the windscreen setting
.
WARNING
In air recirculation mode, no ambient air enters the vehicle interior. If the
air conditioning system is switched off, the windows can quickly mist over.
Therefore, you should never leave the air recirculation mode switched on
for longer periods, as this increases the risk of an accident.
Note
When reverse gear is engaged the air recirculation connects automatically to
prevent the entrance of exhaust fumes in the vehicle on travelling backwards.
The control light on the button does not light up.Economic use of the air conditioningWhen the air conditioning is switched on, the compressor consumes engine
power and has an effect on fuel consumption. Observe the following points
in order to have the equipment operating for a short a time as possible.•
If the vehicle interior has overheated due to excessive solar radiation, it is
best to open the windows or doors to allow the hot air to escape.
•
When travelling the air conditioning should not be switched on if the
windows or sun roof are open.*

For your safety, the windows should never be fogged up or covered with
snow or ice. This is essential to ensure good visibility. Please familiarize
yourself with the correct operation of the heating and ventilation system,
including the demist/defrost functions for the windows.
Note
Please observe the general notes .Automatic mode
In automatic mode air temperature, flow, and distribution are
automatically regulated so that a specified temperature is
attained as quickly as possible and then maintained.Switching on automatic mode
– Press the button . The display is visible ⇒page 119,
fig. 90 .
– Turn the temperature selector to set the desired temperature
inside the vehicle. We recommend 22°C (72°F).
A comfortable interior climate is quickly reached when a temperature of
+22° C (72° F) is set in automatic mode. It can be changed as necessary to
suit individual preferences or particular circumstances. It is possible to select
interior temperatures from +18° C (64° F) to +29° C (86° F). If a lower or higher
temperature is selected, LO or HI is displayed on the screen. These are
approximate temperatures and the actual temperature may be slightly higher
or lower depending on the outside conditions.
Climatronic maintains a constant temperature level fully automatically. The
temperature of the air supplied to the interior, the blower speed and the air
distribution are regulated automatically. The system also allows for the effect
of strong sunlight, so there is no need for manual adjustment. Therefore,
automatic mode provides the best comfort for the vehicle occupants in virtu-
ally all conditions throughout the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, blower or . The temperature continues
to be regulated.Manual mode
In manual mode you can adjust the air temperature, flow, and
distribution yourself.Switching on manual mode
– Press one of the buttons ⇒page 119, fig. 90 to , or turn
the blower control . The display is switched off .Temperature
It is possible to select interior temperatures from +18° C (64° F) to +29° C

Operating instructions
Tips and Maintenance
Te c h n i c a l D a t a
If a temperature below 18°
C (64° F) is selected, the display switches to LO. In
this setting the system runs at maximum cooling output and the temperature
is not regulated.
If a temperature above 29°C (86 F) is selected the display switches to HI. In
this setting the system runs at maximum heating output and the temperature
is not controlled.
Blower
The blower can be infinitely adjusted with the blower control . Always have
the blower running at a low setting to ensure a constant flow of fresh air into
the vehicle. If the blower is switched off (no level displayed ) and the
control is turned further to the left, the Cl imatronic is switched off. In this case
OFF appears on the screen.
Air distribution
The air distribution is adjusted using the buttons , and . It is also
possible to open and close some of the air outlets separately.
Switching the cooling system on and off
Pressing the button switches off the cooling system to save fuel. The
temperature continues to be regulated. The set temperature can then only be
reached if it is higher than the outside temperature.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from entering the vehicle.– Press the button to switch air recirculation mode on or off. This is ON if the symbol

122For the air conditioning system to work with maximum efficiency, the pollu-
tion filter must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the pollution filter must be changed more frequently
than stated in the Service Schedule.
Caution
•
If you suspect that the air conditioner is damaged, switch off the air condi-
tioner with button to prevent further damage and have it checked by a
qualified workshop.
•
Repairs to the air conditioning system require specialist knowledge and
special tools. Therefore, we recommend that you take the vehicle to a quali-
fied workshop should problems occur.Note
•
If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle, this is completely normal and there is no need to suspect
a leak.
•
Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling is not impaired, and to prevent the
windows misting over.
•
The air from the vents flows through the passenger compartment and is
extracted by slots designed for this purpose. Do not cover these slots with
articles of clothing or other objects.
•
The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. However, if the sun has heated up the
vehicle, the air inside can be cooled more quickly by opening the windows for
a short period.
•
Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.
•
At low outside temperatures the compressor switches off automatically.
The button cannot be switched on either.
•
It is advidable to connect the air cond itioning at least once a month, to
lubricate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.
•
For correct operation of the system, do not block the grille between the button and the button
.
•
When the engine is under extreme strain, switch off the compressor for a
moment.

128Glow plug system for the diesel engine
To avoid unnecessary load on the battery, do not use any other major elec-
trical equipment while the glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 63 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely run dry, it may take longer than normal
(up to one minute) to start the engine afte r refuelling with diesel fuel. This is
because the system must eliminate air first.
WARNING
•
Never start or run the engine in un ventilated or closed rooms. The
exhaust fumes contain carbon mono xide, an odourless and colourless
poisonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also cause death.
•
Never leave the vehicle unattended if the engine is running.
•
Never use “cold start sprays”, they could explode or cause the engine
to run at high revs. Risk of injury.Caution
•
When the engine is cold, you should av oid high engine speeds, driving at
full throttle and over-loading the engine. Risk of engine damage.
•
The vehicle should not be pushed or towed for more than approximately
50 metres to start the engine. Fuel could enter the catalytic converter and
damage it.
•
Before attempting to push-start or tow a vehicle to start it, you should first
try to start it using the battery of another vehicle. Note and follow the instruc-
tions ⇒page 214, “Jump-starting”.
For the sake of the environment
Do not warm-up the engine by running th e engine with the vehicle stationary.
You should drive off as soon as you start the engine. This helps the engine
reach operating temperature faster and reduces emissions.Switching off the engine– Stopping the engine.
– Turn the ignition key to position ⇒page 125, fig. 94 .After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched of f. It is also possible that it will turn
itself on once more if the temperature of the coolant increases due to the
elimination of built up heat in the engine compartment or if this is heated due
to prolonged exposure to the heat of the sun.
WARNING
•
Never switch off the engine until the vehicle is stationary.
•
The brake servo works only when the engine is running. You will need
more strength to brake the vehicle when the engine is switched off. As you
cannot brake in the normal manner, there is a greater risk of accidents and
serious injury.
•
The steering lock can engage immediately when the key is removed
from the ignition lock. The vehicle cannot be steered. Risk of accident.

Driving
134HandbrakeUsing the handbrake
The handbrake should be applied firmly to prevent the
vehicle from accidentally rolling away.Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
– Pull the handbrake lever up firmly ⇒fig. 99 .
Releasing the handbrake
– Pull the lever up slightly and press the locking knob in the direc- tion of the arrow ⇒fig. 99 and guide the handbrake lever down
fully ⇒ .
Always apply the handbrake firmly. This prevents you driving with the hand-
brake applied ⇒.
The handbrake warning lamp
 lights up when the handbrake is applied
and the ignition switched on. The warning lamp goes out when the hand-
brake is released.
WARNING
•
Never use the handbrake to slow down the vehicle when it is in motion.
The braking distance is considerably longer, as braking is only applied to
the rear wheels. Risk of accident!
•
If it is only partially released this will cause overheating of the rear
brakes, which can impair the function of the brake system and could lead
to an accident. This also causes premature wear on the rear brake
pads/linings.Caution
Always apply the handbrake before you leave the vehicle. The first gear
should also be selected.Parking
The handbrake should always be firmly applied when the
vehicle is parked.Always note the following points when parking the vehicle:
– Use the foot brake to stop the vehicle.
–Apply the handbrake.
– The first gear should also be selected.

Intelligent technology
142Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during
braking ⇒ page 140.Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒page 65.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheel s of approximately 100 rpm caused by
a slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential.
To prevent the disc brake of the braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The vehicle will continue to
function normally without EDL. For this reason, the driver is not informed that
the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled down.
WARNING
•
When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may start to
spin. This could impair the vehicles stability.
•
Always adapt your driving style to suit road conditions and the traffic
situation. Do not let the extra safety afforded by EDL tempt you into taking
any risks when driving, this can cause accidents.Caution
Modifications to the vehicle (e. g. to the engine, the brake system, running
gear or any components affecting the wh eels and tyres) could affect the oper-
ation of the EDL ⇒ page 162.The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the
car is accelera ting ⇒

Driving and the environment
144Authorised Service Centre more frequently than recommended in the Service
Schedule.
If you drive with wet brakes, for example after driving through water, after
heavy rainfall or after washing the car, the braking effect will be reduced as
the brake discs will be wet, or possibly frozen (in winter): the brakes must be
“dried” through careful braking.
The brake fluid must be changed every two years at the latest. Heavy use of
the brakes may cause a vapour lock if the brake fluid is left in the system for
too long. This prevents the brakes developing their full braking effect.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•
New brake pads must be run in and do not have the correct friction
during the first 200 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also
applies when new brake pads are fitted.
•
If brakes are wet or frozen, or if you are driving on roads which have
been gritted with salt, braking power may set in later than normal.
•
On steep descents if the brakes are excessively used they will over heat
Before driving down a long steep gradient, it is advisable to reduce speed
and change to a lower gear (or move the selector lever to a lower gear if
your vehicle has automatic transmission). This makes use of engine
braking and relieves the brakes.
•
Never let the brakes “rub” by applying light pressure. Continuous
braking will cause the brakes to overheat and will increase the braking
distance. Apply and then release the brakes alternately.
•
Never let the vehicle coast with the engine switched off. The braking
distance is increased considerably as the brake servo does not function.
•
Very heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long. This impairs the braking effect.
•
Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Observe the relevant instructions
before purchasing accessories ⇒page 162, “Modifications”.
•
If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Catalytic converter*To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not run the fuel tank dry.
– For engine oil changes, do not replenish with too much engine oil ⇒page 175, “Topping up engine oil ”.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 214.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 qualified workshop. In general, the exhaust warning lamp will light
up when any of the described symptoms occur ⇒page 60. If this happens,
unburnt fuel can enter the exhaust system and escape into the environment.
The catalytic converter can also be damaged by overheating.
