Heating and air conditioning
WARNING
Never use the air recirculation system for too long, as it prevents fresh air
from entering the vehicle and “used” air can cause tiredness, reduce your
attention span and cause the windows to mist over. This increases the
risk of an accident. Switch off the air recirculation system as soon as the
windows begin to mist over.
Air conditioning (manual)* General notes
The air cooling system only works if the AC button
2 ⇒ Fig. 99
⇒ page 129 is pressed and under following conditions:
● The engine is running
● The outside temperature is above +2 °C (+36 °F)
● The blower control is in position 1 – 4
When the cooling system is on and under certain conditions, air can be
blown from the vents at a temperature of approx. 5 °C (41 °F). In the event
of prolonged, irregular distribution of the air flow from the outlets and sig-
nificant differences in temperature, e.g. on leaving the vehicle, sensitive
people may catch a cold.
Note
A visit to the specialised service once a year is recommended to clean the
air conditioning system. Operation

Climatronic* (automatic air conditioning) General notes
Climatronic automatically maintains a comfortable temperature. To do so, it
automatically regulates the supplied air temperature and the blower and air
distribution levels. The system also allows for the effect of sunlight, so there
is no need for manual adjustment. Automatic operations ⇒ page 133 guar-
antee maximum comfort any time of year.
Climatronic description
Cooling only works if the following conditions are met:
● The engine is running
● The outside temperature is above +2 °C (+36 °F)
● AC
18 ⇒ Fig. 100 ⇒ page 133 on. In order to ensure engines subject to heavy loads are cooled, the air condi-
tioning compressor is switched off in the event of high coolant tempera-
tures.
Recommended setting for all seasons
●
Set the required temperature. We recommend 22 °C (72 °F).
● Press the AUTO
button 12 ⇒
Fig. 100 ⇒ page 133.
● Adjust vents 3 ⇒ page 126 and 4 so that the air flow is directed slightly
upwards.

and AC buttons
⇒ Fig. 100 ⇒ page 133 pressed down at
the same time. The data is displayed on the screen in the units required.
Note
A visit to the specialised service once a year is recommended to clean the
Climatronic system.
134Heating and air conditioning
Temperature selection
–When you switch on the ignition, control 1 ⇒ Fig. 100
⇒ page 133 can be used to set the required interior tempera-
ture.
The interior temperature can be set to between +18 °C (+64 °F) and +29 °C
(+84 °F). The temperature is regulated automatically within this range. If a
temperature below +18 °C (+64 °F) is selected, “LO” is displayed on the
screen. If a temperature above +29 °C (+84 °F) is selected, “HI” is displayed
on the screen. At both extremes, Climatronic works at maximum cooling or
heating power, respectively. The temperature is not regulated.
In the event of prolonged, irregular distribution of the air flow from the out-
lets (particularly the footwells) and significant differences in temperature,
e.g. on leaving the vehicle, sensitive people may catch a cold.
Air recirculation
Air recirculation prevents unpleasant smells, e.g. when passing
through a tunnel or in queuing traffic, from entering the interior.
Switching on air recirculation mode

sym-
bol disappears from the screen.
WARNING
Never use the air recirculation system for too long, as it prevents fresh air
from entering the vehicle and “used” air can cause tiredness, reduce your
attention span and cause the windows to mist over. This increases the
risk of an accident. Switch off the air recirculation system as soon as the
windows begin to mist over.
Note
If air recirculation mode remains on for 15 minutes, the symbol will
start to flash on the screen to indicate prolonged air recirculation. If air recir-
culation is not switched off, the symbol will continue to flash for 5 minutes.
Blower selection
Climatronic automatically regulates the blower speed according to
the interior temperature. It is possible, however, to set the blower
speed to suit requirements.
– Turn rotary control 10
⇒ Fig. 100 ⇒
page 133 anti-clockwise
(decrease speed) or clockwise (increase speed).
Climatronic will switch off when the blower switches off.
WARNING
● “Used air” can cause tiredness, reduce attention spans and cause the
windows to mist over. This increases the risk of an accident.
● Do not switch off Climatronic for longer than necessary.
● Switch Climatronic back on as soon as the windows begin to mist
over.

Introduction
WARNING
● Never adjust the steering wheel while the vehicle is moving!
● Maintain at least 25 cm distance between the steering wheel and the
upper part of your body 1
⇒ Fig. 101
⇒ page 137. The airbag system
will not be able to give the required protection if the minimum distance is
not observed. This can cause a risk of fatal injury!
● For safety reasons, the steering wheel adjustment lever must always
be pushed securely against the steering column to prevent the steering
wheel from accidentally changing position while driving. Risk of acci-
dent!
● If the steering wheel is adjusted closer to your face, the protective ef-
fect of the driver airbag will be decreased in the event of an accident.
Check that the steering wheel is pointing towards the upper part of your
body.
● When driving, always hold the steering wheel with both hands on the
outside part at the 9 o'clock and 3 o'clock positions. Never hold the
steering wheel at the 12 o'clock position, or in any other manner (e.g. in
the centre of the steering wheel). In such cases, if the airbag is triggered,
you may sustain injuries to the arms, hands and head.
● When moving with the engine switched off, the ignition key must al-
ways remain in position 2
⇒ Fig. 102 ⇒
page 138 (ignition on). The
control lamps will light up in this position. Otherwise, the steering lock
could engage suddenly. Risk of accident!
WARNING (Continued)
● Do not remove the key from the ignition until the vehicle has come to
a standstill and is secure (e.g. the handbrake is engaged). Otherwise, the
steering lock could suddenly engage. Risk of accident!
● Always take the ignition key with you when you leave the vehicle.
This is particularly important if you leave children in the vehicle. Children
could start the engine, for example, with the subsequent risk of accident.
● Never leave the engine running in unventilated or closed rooms. The
exhaust gases contain carbon monoxide, an odourless and colourless
poisonous gas. Risk of fatal accidents! Carbon monoxide can cause peo-
ple to lose consciousness and can cause death.
● Never leave the vehicle unattended if the engine is running.
● Never switch the engine off until the vehicle is stationary. Risk of ac-
cident!
CAUTION
● Turning the steering wheel fully in either direction when the vehicle is
stationary and the engine in gear puts the power steering under great
stress. This could lead to noise. Never leave the steering wheel turned fully
in either direction for more than 15 seconds. Risk of damage to the power
steering system!
● The starter motor may only be used (key position 3
⇒ Fig. 102
⇒ page 138 in the ignition) if the engine is off. Using the starter motor
when the engine is running could cause damage.
● Immediately release the ignition key when the engine starts, otherwise
damage could be caused to the starter motor.
● When the engine is cold, you should avoid high engine speeds, driving
at full throttle and over-loading the engine before it reaches operating tem-
perature. Risk of engine damage!

engine can be started straight away when the lamp switches off.
Do not connect electrical appliances during preheating so as not the drain
the vehicle battery unnecessarily.
Starting the engine
● Move the gearbox lever into neutral or move the selector lever to posi-
tion P or N and pull firmly on the handbrake.
● Press the clutch pedal all the way down 2
⇒ Fig. 102 ⇒ page 138 and
start the engine 3 – without pressing the accelerator. Keep the clutch ped-
al pressed down until the engine starts.
● Release the ignition key as soon as the engine starts. The key returns to
position 2
.

● Release the handbrake before moving off.
Switching off the engine
Stop the engine by turning the ignition key to position 1 ⇒ Fig. 102
⇒ page 138.
Brakes and brake servo systems Introduction
WARNING
● The brake servo only works when the engine is running. Braking
when the engine is switched off requires more strength on the brake ped-
al. Risk of accident!
● Press down on the clutch pedal when stopping and braking with a
manual gearbox, petrol engine vehicle at low speed. Otherwise, the
brake servo might not work properly. Risk of accident!
● In the event of damage to the standard front spoiler or where a differ-
ent front spoiler, hubcaps, etc. are subsequently fitted, make sure the air
vent to the brakes on the front wheels is not blocked. Otherwise, braking
operations may be impaired. Risk of accident!
● Always fully release the handbrake. If it is only partially released, this
will cause overheating of the rear brakes, which can impair the function
of the brake system. Risk of accident!
WARNING (Continued)
● Never leave children unsupervised in the vehicle. They could release
the handbrake or move the gear lever. The vehicle could start moving.
Risk of accident!
● Insufficient fuel can cause the engine to run irregularly or to switch
off. Brake assist systems could be impaired. Risk of accident!
● Always adjust your driving style to suit visibility, the weather and
road and traffic conditions. The best vehicle safety offered by brake as-
sist systems must never encourage you to run greater risks. Risk of acci-
dent!
CAUTION
● Observe the information concerning new brake pads ⇒ page 154.
● Where braking is not necessary, do not wear down the brake pads by
pressing down gently on the brake pedal. This causes the brakes to over-
heat, increasing their wear and increasing braking distances.
● To ensure the brake assist systems work properly, all wheels must be fit-
ted with tyres approved by the manufacturer.
Note
● If you brake suddenly and the brake system control unit regards the sit-
uation as hazardous for the drivers behind you, the brake lights will begin
to flash automatically. After reducing speed to approx. 10 km/h (6 mph) or
stopping the vehicle, the brake lights will stop flashing and the hazard
warning lights will switch on. The hazard warning lights are automatically
switched off when you accelerate or restart the vehicle.
● On long, steep gradients, reduce your speed and change to a lower gear
(manual gearbox) or move the selector lever to a lower gear position (auto-
matic gearbox). This uses the force of the engine and the brakes do not suf-
fer as much. If you still have to brake, do so intermittently, pressing down
repeatedly on the brake pedal.

140Driving
● Vehicle modifications (e.g. to the engine, brakes, frame or a combina-
tion of wheels and tyres) could impair the brake assist systems
⇒ page 195, Accessories, modifications and spare parts.
● In the event of a fault in the ABS system, the ESC, ASR and EDL are
switched off automatically. A fault in the ABS is indicated by the
⇒ page 70 warning lamp.
Brakes
Wear
The rate of wear of the brake pads depends on the driving style and on the
way in which the vehicle is used. The brake pads will wear more quickly if
you use your vehicle frequently in urban traffic and short trips or drive in a
sporty style. Under these demanding conditions, visit your specialised serv-
ice, even before the scheduled service date, so that the thickness of the
brake pads can be measured.
Wet roads or road salt
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. Dry the brakes
as soon as possible by braking repeatedly.
Corrosion
Long periods of inactivity and little use can lead to rust on the brake discs
and dirt on the brake pads. Where the brake system is subjected to light
stress or in the case of corrosion, clean the brake discs by braking fully sev-
eral times at a high speed.
Brake system fault
If you notice that the braking distance suddenly increases and the brake
pedal can be pressed down more fully, there may be a fault in the brake sys-
tem. Visit a specialised service immediately and adjust your driving style to
the extent of the damage and to limit the effect of the brakes. Low brake fluid level
Insufficient brake fluid could cause faults in the brake system. The brake flu-
id level is controlled electronically
⇒ page 66, Brake system .
Brake servo
The brake servo supplements the pressure you exert on the brake pedal.
The brake servo only works when the engine is running.
Handbrake

Applying the handbrake
– Pull the handbrake lever up all the way.
Releasing the handbrake
– Pull the handbrake lever up slightly and press the unlock button
at the same time ⇒ Fig. 103.
– Keep the button pressed down and push the lever all the way
down.
141
Driving
The warning lamp lights up when the handbrake is applied with the ignition
on .
Stability system (ESC)
Fig. 104 ESC system:
ASR switch
The ESC system increases control of the vehicle in emergency situations,
e.g. during a sudden change in direction. Depending on the driving condi-
tions, it reduces the risk of skidding and increases driving stability.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. When irregularities occur, for exam-
ple, if the vehicle begins to skid, the ESC brakes the appropriate wheel au-
tomatically.
The warning lamp in the general instrument panel starts flashing when
the system is working.
The stability (ESC) system includes the following systems:
● Anti-lock brake system (ABS)
● Traction control system (ASR)
● Electronic differential lock (EDL) ●
Brake assist system (HBA)
● Hill hold control (HHC)
The ESC system cannot be switched on. The
⇒ Fig. 104 button can only
be used to switch off the ASR system. The warning lamp lights up on the
general instrument panel if the ASR system is switched off.
The ASR should be switched on at all times. Only under certain circumstan-
ces should the system be switched off, e.g.
● Driving with chains
● Driving in deep snow or on very soft surfaces
● During the “swinging movement” required to remove a stuck vehicle
Switch the ASR back on as soon as possible.
Brake assist system (HBA)*
The HBA system is activated when you press down on the brake pedal sud-
denly. It increases braking power, helping to reduce braking distances. To
reduce the braking distance as much as possible, keep the brake pedal
pressed down firmly until the vehicle comes to a standstill.
With the help of this system, the ABS is activated more quickly and more
efficiently.
The brake assist function is deactivated automatically when the brake pedal
is released.
Hill hold control (HHC)*
The HHC system makes it easier to start the vehicle on hills. The system
maintains the brake pressure created by pressing down on the brake pedal
for 2 seconds after it has been released. Your foot can be removed from the
brake pedal and you can use the accelerator pedal and move away on a hill
without having to use the handbrake. The brake pressure drops as the ac-
celerator pedal is pressed. If the vehicle is not started then it will start to
move backwards after two seconds.
