Heating and cooling
Heating and cooling
Heating system/air
conditioner
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.
Default settings
Default settings for certain functions can be se­
lected on the infotainment system.
SeLect the following on the infotainment system:

Supplementary heater*
Applies to: vehicles with diesel engine
The vehicle interior warms up more quickly with
the supplementary heater. The system automati­
cally switches the supplementary heater on
tem­

porarily as required, depending on the setting on
the vehicle heating system.
The supplementary heater function can be
switched on or off as required. SeLect the follow­
ing on the infotainment system:

- Keep the air intake slots in front of the
windscreen clear of snow, ice and Leaves to
ensure unimpaired heating and cooling, and
to prevent the windows misting over.
- Condensation can drip off the air cooling

system*
and form a pool underneath the ve­

hicle.
This is normal and does not indicate a
leak.
- If
you
notice, for instance, that the seat* or
rear window heating is not working, it may
have been temporarily switched off by the
power management function. These sys­
tems will be available again as soon as
suffi­

cient electrical power is available.

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*.

Checking and topping up fluids
Selective catalytic
reduction (AdBLue/DEF)
General notes
Applies to: vehicles with selective catalytic reduction
On vehicles with selective catalytic reduction, a
urea solution (AdBLue/DEF) is injected into the
exhaust system upstream of
a
NOx catalytic
con­

verter in order to reduce nitrogen oxide emis­

sions.
The urea solution is known under the name
of AdBlue or DEF (Diesel Exhaust Fluid). The term
AdBlue is used below.
The AdBlue is held in a separate tank on the
vehi­

cle.
AdBlue consumption is approximately 1.0 -
2.5% of diesel fuel consumption.
As soon as a message appears in the instrument
cluster display reminding you to refill AdBlue,
you must refill the AdBlue tank or have this done
by
a
qualified workshop
^>page
293.
Checking the remaining range
The remaining (estimated) range for the current

AdBLue
level can be displayed on the on-board
computer:

dry, the engine cannot be started again af­
ter you switch off the ignition.
-The use of
AdBLue for
the operation of this
vehicle is required by Law.

- Incorrect tyre pressures increase tyre wear
and adversely affect vehicle braking and
handling - risk of accident!
(7) CAUTION
Replace any lost valve caps to prevent dam­
age to the tyre valves.

(#) For
the sake of the environment
- Under-inflated tyres will increase the fuel
consumption.
- Driving with the tyre pressures adjusted to

WARNING
If the wheel bolts have not been tightened or
serviced correctly, they can come loose, and
you could lose control of the vehicLe - risk of
accident! For the correct tightening torque,
refer to
^page
324, After changing a wheel.
- Make sure that the wheel bolts and threads
in the wheel hubs are always clean and free
from grease.
- Only use wheel bolts that are designed to
match the rims on your car.
- Always have damaged rims repaired by a
qualified workshop. Never attempt to repair
or dismantle rims yourself - risk of accident!
Winter tyres
In winter road conditions winter tyres will consid­
erably improve the car's handling. Due to their
type of construction (width, rubber compound,
tread pattern), summer tyres give less grip on ice
and snow.

•
Winter tyres must be fitted on all four wheels.

•
Only use winter tyres of the correct type ap­
proved for your vehicle.

•
Please note that the maximum permissible
speed for winter tyres may be lower than for
summer tyres
•=> A-
Your specialist retailer can
advise you of the maximum speed
for
your

tyres.

•
After fitting the wheels you must always check
the tyre pressures
^>page
307.
Winter tyres Lose their effectiveness when the
tread is worn down to a depth of 4 mm. The per­
formance of winter tyres is also severely impaired
by ageing, even if the tread is still much deeper
than 4 mm.
A WARNING
- Never exceed the maximum approved speed
for your tyres. This causes the tyres to over­
heat and can even result in a blow-out - risk
of accident!
- Always adapt your driving style to the pre­
vailing road and traffic conditions. Drive
carefully and reduce your speed on icy or
slippery roads. Even winter tyres lose their
grip on black ice.

(^)
For the sake of the environment
Summer tyres should be fitted again as soon
as possible; they give better handling on
roads which are free of snow and ice. They are
quieter, do not wear so quickly and reduce
fuel consumption. •
