- In icy conditions, check that the wiper
blades are not frozen to the windscreen. If
the wiper blades are frozen to the
wind
screen when you switch on the windscreen
wipers, this could damage the wiper blades.
- Make sure you switch off the windscreen
wiper system (lever in position

before
you use an automatic car wash. This will
avoid inadvertent triggering of the wipers
and possible damage to the wiper system.
© Note
- The windscreen wipers are deactivated
when the ignition is switched off. You can
activate the windscreen wipers after switch
ing the ignition on again by moving the
windscreen wiper lever to any position.
- Worn or dirty wiper blades can cause smear

fectiveness of the rain sensor. Please check
the wiper blades regularly.
-The windscreen washer jets are heated*
when the ignition is switched on if the out

Cleaning the wiper blades
Clean the wiper blades if the wipers leave smear

Description
One of the following systems may be fitted, de
pending on the equipment in your vehicle:
- Heating and ventilation system or
- Manual air conditioner* or
- Automatic air conditioner* (deluxe version)
The heating and ventilation system* heats and
ventilates the vehicle interior. The air condition
er* additionally cools and dehumidifies the air in
side the vehicle. It operates most effectively with
the windows and the panorama sun roof* closed.
If the vehicle has been standing in the sun, it may
cool down faster if
you
open the windows briefly
to let the hot air escape.
Pollution filter
The pollution filter removes impurities, such as
dust and pollen, from the air.
Key-coded settings
Various settings are stored and assigned to the
remote control key in use.

Driving
instance when you can see that the next traffic
lights are red. This takes advantage of the engine
braking effect, reducing wear on the brakes and
tyres.
Emissions and fuel consumption will drop
to zero due to the overrun fuel cut-off.
Change gear early to save fuel
An effective way of saving fuel is to change up
quickly through the gears. Running the engine at
high rpm in the lower gears uses an unnecessary
amount of
fuel.
Applies to: vehicles with manual gearbox
Shift up to second gear as soon as possible. If
possible, we recommend shifting up to the next
gear at approx. 2,000 rpm.
Applies to: vehicles with automatic gearbox
Press the accelerator slowly and avoid using the
"kick-down"
feature.
Avoid driving at high speed
Avoid travelling at top speed. Fuel consumption,
exhaust emissions and noise Levels all increase
very rapidly at higher speeds. Driving at moder
ate speeds will help to save
fuel.
Do not let the engine idle for longer than
necessary
Engine idling periods are automatically reduced
on vehicles with start/stop system*. On vehicles
without a start/stop system, it is worthwhile
switching off the engine at level crossings, for in
stance, or at traffic lights with a long red phase.
The fuel saved after about 5 seconds can be
greater than the amount of fuel needed to re
start a warm engine (the exact fuel saving de
pends on the engine version).
The engine takes a very long time to warm up
when it is running at idling speed. 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.
o
Regular servicing
Regular servicing can establish a basis for good
iS
fuel economy before you start driving. A
well-
serviced engine gives you the benefit of im
proved fuel efficiency as well as maximum relia
bility and an enhanced resale value. A poorly
maintained engine can consume up to ten per
cent more fuel than necessary.
Avoid short trips
The engine and emission control system need to
reach their proper working temperature in order
to minimise fuel consumption and emissions.
A cold engine uses disproportionately more
fuel.
The engine only reaches its working temperature
after about four kilometres, when fuel consump
tion will return to a normal level.
Check tyre pressures
Always make sure the tyres are inflated to the
correct pressures
•=>page
306 to save
fuel.
If the
tyre pressures
are
just 0.5
bar
too Low, this can
increase the fuel consumption by as much as 5
%. Due to the greater rolling resistance, under-
inflation also increases tyre wear and impairs
handling.
Do not use winter tyres all through the year; they
will increase fuel consumption by up to 10 %.
Avoid carrying unnecessary loads
Every kilo of extra weight will increase the fuel
consumption, so it is worth checking the Luggage
compartment occasionally to make sure that no
unnecessary loads are being transported.
The roof carrier increases the air resistance of the
vehicle and should be removed when not in use.
This will save about 12 % of fuel at speeds of be
tween 60 and 75
mph.
Save electrical energy
The engine drives the alternator to generate elec
tricity. This means that fuel consumption rises
when more power is required for electrical equip
ment. Switch off electrical equipment when it is
not needed. Electrical equipment which uses a
lot of electricity includes the blower (at a high
setting), the rear window heating and the seat
heating*.

A WARNING
- Never run the engine in confined spaces.
The exhaust gases are toxic - risk of poison
ing!
- Never remove the key from the ignition
while the vehicle is moving. The steering
lock would engage, and you would not be
able to steer the car - risk of accident!
© CAUTION
Avoid high engine speeds, full throttle and ex
treme load conditions until the engine has
reached its normal operating temperature;
otherwise this can damage the engine.
© For the sake of the environmen
Do not warm up the engine by running it with
the car stationary. You should drive off imme
diately whenever possible. This will help avoid
unnecessary exhaust emissions.
© Note
- If it is difficult to turn the ignition key to po
sition ®, move the steering wheel (to take
the load off the steering lock mechanism)
until the key turns freely.
- Any noises which may be heard when the
engine is started are quite normal and no
cause for concern.

WARNING
- Never switch off the engine until the vehicle
is stationary. Otherwise you may not have
the full benefit of the brake servo and pow
er steering. You may need more strength to
steer and brake the vehicle than you nor
mally would. This would mean a greater risk
of accidents and serious injury, because you
cannot steer and brake in the normal
man
ner.
- Never remove the key from the ignition
while the vehicle is moving. The steering
lock could engage suddenly, and you would
not be able to steer the car.
- Always take the key with you when you leave
the vehicle. Otherwise the engine can be
started or power-operated equipment such
as the electric windows can be used. This
could result in serious injury.
- When parking, always move the selector
lever to position

to prevent the vehicle
from rolling back accidentally.

If the engine has been working hard
fora
