Auxiliary heating (auxiliary heating and ventilation)
Description and important information The auxiliary heating (auxiliary heating and ventilation) heats or
supplies the interior of the vehicle with fresh air independent of the
engine.
Auxiliary heating (auxiliary heating)
The auxiliary heater (parking heater) functions in connection with the air-condi-
tioning system or Climatronic.
It can be used when stationary, when engine is switched off for preheating of the
vehicle as well as while driving (e.g. during the heating phase of the engine).
The engine is also preheated when the vehicle is stationary and the engine is
switched off, if the auxiliary heating is switched on.
The auxiliary heating (auxiliary heating) warms up the coolant during the combus-
tion of fuel from the vehicle tank. The coolant warms up the air, which (if the
blower speed is not set to zero) flows into the occupant compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun). WARNING
● The auxiliary heating must never be operated in closed rooms - risk of poi-
soning!
● The auxiliary heating must not be running during refuelling - risk of fire.
● The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. Therefore do not place the vehicle, if you wish to operate the aux-
iliary heating, in such a way that the exhaust gases of the auxiliary heating
can come easily into contact with inflammable materials (e.g. dry grass) or
easily inflammable substances (e.g. fuel run out). Note
If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
The auxiliary heating automatically controls the filling level in the fuel tank. If only
a low quantity of fuel is present in the fuel tank, the function of the auxiliary heat-
ing is blocked.
● The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
● If the auxiliary heating and ventilation is running, the vehicle battery discharg-
es. If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometres in order to recharge the
vehicle battery.
● The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50
°C.
● At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating
problem.
● After switching off the auxiliary heating, the coolant pump runs for a short pe-
riod.
● The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicates a low loading state.
● The auxiliary heating (auxiliary heating) does not switch on, if the following
was shown in the information display or before switching off the ignition: Please
refuel! £ 95

For switching on, press the button ON .
– For switching off, press the button OFF .
The transmitter and the battery are housed in the housing of the remote control.
The receiver is located in the interior of the car.
If the battery is properly charged, the effective range is up to 600
m. For switching
on or off the auxiliary heating, hold the remote control vertically with the antenna A
⇒ fig. 94 towards the top. You must not cover over the antenna with the fin-
gers or the palm of the hand. Obstacles between the radio remote control and the
vehicle, bad weather conditions and a weaker battery can clearly reduce the
range. The auxiliary heating can only be switched on or off with the radio remote control,
if the distance between the radio remote control and the vehicle is at least 2 m.

Starting-off and Driving
Setting steering wheel position Fig. 95 Adjustable steering wheel: Lever next to the steering column/safe distance to the
steering wheel
You can set the height and the forward/back position of the steering wheel to the
desired position.
– Adjust the driver seat ⇒ page 61.
– Pull the lever below the steering wheel down ⇒ fig. 95 - left ⇒ .
– Set the steering wheel to the desired position (concerning height and forward/
back position).
– Push the lever upwards as far as the stop. WARNING
● You must not adjust the steering wheel when the vehicle is moving!
● The driver must maintain a distance of at least 25 cm to the steering wheel
⇒ fig. 95 - right. Not maintaining this minimum distance will mean that the air-
bag system will not be able to properly protect you - hazard!
● For safety reasons the lever must always be firmly pushed up to avoid the
steering wheel altering its position unintentionally when driving - risk of acci-
dent! WARNING (Continued)
● If you adjust the steering wheel further towards the head, you will reduce
the protection offered by the driver airbag 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 de-
ployed.

Starting-off and Driving Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data
CAUTION
● The starter may only be operated (ignition key position 3 ), if the engine is not
running. If the starter is immediately operated 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 operating temperature - risk of damag-
ing the engine!
● Do not tow start the engine - danger of damaging the engine. On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. You can
use the battery of another vehicle as a jump-start aid ⇒ page 216, Jump-starting
.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 electrical fuel pump is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒ page 220.
● 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 away and 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.
● Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the 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 off the engine –
The engine can be switched off by turning the ignition key into position 1 ⇒
fig. 96 . 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 period at high loads but should be al-
lowed it to run at idling speed for about 2
minutes. This prevents any accumula-
tion of heat when the engine is switched off. £ 101

The handbrake warning light
lights up when the handbrake is applied, provided
the ignition is on.
A warning signal sounds and the following text appears in the Information display
if you have inadvertently driven off with the handbrake applied:
Release parking brake!
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 result in the rear brakes overheating which will
have a negative effect on the 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 ex-
ample, 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 first of all apply the handbrake firmly be-
fore then additionally engaging a gear (manual gearbox) or moving the selector
lever into position P (automatic gearbox).
Rear parking aid The parking aid provides a warning of obstacles behind the vehicle.
Fig. 99 Parking aid: Detection range of
rear sensorsThe audible parking aid determines the distance from the rear bumper to an ob-
stacle behind the car with the aid of ultrasound sensors. The tones of the parking
aid can be adapted in the menu of the Information display
⇒
page 20. The sensors
are integrated in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle
(area A ⇒
fig. 99 ). The interval between the warning signals becomes shorter as
the clearance is reduced.
A continuous tone sounds from a distance of approx. 30 cm (area B ) - danger
area. You should not reverse any further after this signal sounds! If the vehicle is
equipped with a factory-fitted towing device, the indication threshold of the dan-
ger area starts -
continuous tone - 5 cm further behind the vehicle. The vehicle
can be extended through an installed detachable towing device.
On factory-fitted radio navigation systems and car stereos, the distance to the ob-
struction can also be shown graphically in the display. On vehicles with a factory-
fitted towing device, the rear sensors are deactivated when towing a trailer. The
driver is informed about this by a graphic display (vehicle towing a trailer) in the
radio or the radio navigation display. The factory-fitted radio or navigation system
can be set so that the play function volume decreases when activating the park-
ing aid, see Owner's Manual radio or radio navigation system. As a result, the sig-
nal tones from the parking aid can be better recognised.
Activating
The parking aid is activated automatically when reverse gear is engaged and the
ignition is turned on. This is confirmed by a brief audible signal.
Deactivating
The parking aid is deactivated by removing the reverse gear. £ 103

WARNING
● The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when reversing the ve-
hicle or carrying out similar manoeuvres.
● You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., in front or behind
your vehicle. Such an obstacle might not be within the range detected by the
sensors.
● Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the park-
ing aid. Note
● Only the front parking aid operates if you are towing a trailer (applies only to
models which feature a factory-fitted towing device).
● If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. The fault is
confirmed additionally when the symbol flashes in the button
⇒ fig. 100 - left.
Have the fault rectified by a specialist workshop.
● The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
● If the parking aid is activated and the selector lever of the automatic gearbox
is in the position P , warning signal indicates interruption (vehicle can no longer
move).
Park Assist Description and important information The park assist assists you when parking in a suitable parallel parking space be-
tween two vehicles or behind a vehicle.
The park assist automatically searches for suitable parking spaces after switching
on the ignition and when driving up to 30 km/h.
During the parking procedure the park assist only takes over the steering move-
ments, the pedals continue to be operated by the driver. Function of the system is based on:
●
Length and depth measurement of the parking spaces when driving
● Evaluation of the size of the parking space
● Definition of the correct position of the vehicle for parking
● Calculating the line on which the vehicle drives backwards into the parking
space
● Actuation of the steering force assistance, automatic spinning of the wheels
of the front axle when parking. WARNING
The park assist does not take away the responsibility from the driver when
parking.
● Pay particular attention to small children and animals as they would not be
recognised by the sensors of the parking aid.
● Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the park assist or the parking aid. Thus,
these objects or people who wear such clothing are not recognised by the
sensors of the parking aid.
● The external sound source of the park assist and the parking aid can be
disruptively influenced and under unfavourable conditions, objects or people
cannot be recognised by the sensors of the parking aid. CAUTION
● If other vehicles are parked behind or on the kerb, the park assist guides your
vehicle beyond the kerb or onto it. Make sure that the wheels or the wheel rims of
your vehicle are not damaged and if necessary intervene in time.
● You should satisfy yourself before parking that there is no small obstacle, such
as a rock, thin post, trailer drawbar etc., in front or behind your vehicle. Such an
obstacle might not be within the range detected by the sensors.
● Under certain circumstances, surfaces or structures of certain objects such as
wire mesh fences, powder snow etc..., cannot be recognised by the system.
● The evaluation of the parking space and the parking procedure depends on
the circumference of the wheels. Under certain circumstances, the system may
not function correctly if your vehicle is mounted with wheels of non-permissible
size, snow chains or a temporary spare wheel (in order to reach the nearest work-
shop). If the tyres other than those excepted by the manufacturer are mounted,
the resulting position of the vehicle in the parking space can differ slightly. The
parking assistant system automatically performs the correction of the wheel cir-
cumference when driving. £ 105

Note
● Models fitted with a manual gearbox: Always depress the clutch pedal if you
switch on the cruise control system when the gearbox is in Neutral! Otherwise the
engine can rev up unintentionally.
● The cruise control system is not able to maintain a constant speed when driv-
ing on steep downhill sections. The weight of the vehicle increases the speed at
which it travels. One should shift down in good time to a lower gear or slow the
vehicle down by applying the foot brake.
● It is not possible on vehicles fitted with an automatic gearbox to switch on the
cruise control system if the selector lever is in the position P, N or R.
Storing a speed Fig. 104 Operating lever: Rocker button
and switch of the cruise control system
The cruise control system is operated by means of the switch A
⇒ fig. 104 and
the rocker button B in the left lever of the multi-functional switch.
– Press the switch A
⇒ fig. 104 into the position ON.
– After the desired speed has been reached, press the rocker button B into the
SET position.
After you have released the rocker button B out of the position SET
, the speed
you have just stored is maintained at a constant speed without having to depress
the accelerator.
You can increase the speed by depressing the accelerator. Releasing the accelera-
tor 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 saved speed for a period of more than 5
minutes. The stored
speed will be cancelled in the memory. You then 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 110. 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.
Faster
– You can increase the stored speed without depressing the accelerator, by
pressing the rocker button B
⇒
fig. 104
in the RES position.
– The speed of the car will increase continuously if you hold the rocker button
pressed in the RES position. Once the car has reached the desired speed, re-
lease the rocker button. The set speed is then stored in the memory.
Slower
– You can decrease the stored speed by pressing the rocker button B in the
SET- position.
– Holding down the rocker button pressed in the SET position will cause the
speed of the vehicle to reduce continuously. Once the car has reached the de-
sired 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 neces-
sary to again store the speed with the rocker button B in the position
SET
after an increase in speed of the vehicle to more than 30 km/hour. 109
