Air recirculation mode
In air recirculation mode, the air from the interi

Rear window heating
If the rear window heating is activated with the
ignition switched on, the battery management
determines whether or not the vehicle battery
charge level is sufficient for the rear window
heating to be switched on. Otherwise the rear
window heating operates when the engine is
run
ning,
and switches off automatically after about
10 - 20 minutes, depending on the outside
tem
perature.
To switch on the rear window heating perma
nently, press and hold the
CÛJD
button for at least
2 seconds. This setting will be stored for approxi
mately 15 minutes after the ignition is switched
off.

Seat heating*
When you press the
«0
button, the seat heating is
switched on at level 3 (the highest level). The
LEDs indicate the temperature level. To reduce
the temperature, press the button again. To
switch off the seat heating, press the button re
peatedly until all the LEDs have gone out.
The seat heating automatically switches from
level 3 to level 2 after about 10 minutes.
(7) CAUTION
To avoid damaging the heating elements of
the seat heating, please do not kneel on the
seat or apply sharp pressure at
a
single
point
© Note
- The setting for the driver's seat heating is
assigned to the key in use.
- If the front passenger's seat heating was on
when you Last switched off the ignition, it
will be switched on automatically only if the
ignition is switched on again within 10 mi
nutes.

WARNING
- For reasons of safety you should not Leave
the air recirculation switched on for too
long.
This mode prevents fresh air from en
tering the vehicle, so the windows can mist
over if the air cooling* is switched off. Bad
visibility can cause an accident.
- People with limited capacity to feel pain or
sense temperature could burn themselves
when using the seat heating. These people
must not use the seat heating - risk of in

is activated if you press the
AUTO button briefly while automatic mode is ac

General notes
Running in
A new vehicle should be run in over
a
distance of
1,500 km. For the first 1,000 km the engine
speed should not exceed 2/3 of the maximum
permissible engine speed - do not use full throt
tle and do not tow a trailer or caravan. From
1,000 to 1,500 km you can gradually increase
the engine rpm and road speed.
During its first few hours of running, the internal
friction in the engine is greater than later on
when all the moving parts have bedded down.
How the vehicle is driven for the first 1,500 km
also influences the engine quality. After this
peri
od you should continue driving at moderate en
gine speeds, in particular when the engine is
cold.
This helps to reduce wear and tear on the
engine and increases the potential mileage which
can be covered by the engine.
You should also avoid driving with the engine
speed too low. Change down to a lower gear
when the engine no longer runs "smoothly". Ex
cessively high engine speeds are prevented by an
automatic rev limiter.
A WARNING
After driving through water, mud, sludge,
etc., the braking effect can be delayed slightly
due to moisture on the discs and brake pads.
Applying the brakes carefully several times
will remove the moisture and restore the full
braking effect.
© CAUTION
- Parts of the vehicle (e.g. engine, gearbox,
running gear or electrical components) can
be badly damaged when driving through
water.
- Always switch off the start/stop system*
^>page
79 before driving through water.
© ' Note
- It is advisable to check the depth at the
deepest point before approaching the wa
ter.
- Do NOT stop the vehicle, drive in reverse or
switch off the engine before you are out of
the water.
- Bear in mind that waves created by oncom
ing traffic could exceed the permissible
wading depth of your vehicle.
- Avoid driving through salt water (corrosion).
Avoiding damage to the car
© CAUTION
Take care not to damage
Low-mounted
parts
of the car (such as the spoiler or exhaust sys
tem) on steep ramps, uneven road surfaces or
roadside kerbs, etc. This applies especially to
vehicles with low ground clearance and to all
vehicles when fully laden.
Driving through water on roads
Please note the following in order to prevent
damage to the vehicle when driving through wa
ter (e.g. on flooded roads):
- The water level must not be higher than the ve
hicle's underbody.
- Do not drive faster than walking pace.
How to improve economy and minimise
pollution
Fuel economy, environmental impact and wear
on the engine, brakes and tyres depend largely
on the way you drive the vehicle. By adopting an
economical driving style and anticipating the
traffic situation ahead, you can reduce fuel
con
sumption by 10
-15
%. The following section
gives you some tips on Lessening the impact on
the environment and reducing your operating
costs at the same time.
Anticipate well in advance
A car uses most fuel when accelerating. If
you
an
ticipate hazards and speed changes well in ad
vance,
you will need to brake less and thus accel
erate Less. Wherever possible, Let the car slow
down gradually with a gear engaged, for •
72

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*.
