and the vehicle's lights are off. The illumi­
nation of the diaLs and needles is automati­
cally reduced as it becomes dark outside

nition is switched on. In order to avoid possible
damage to the engine, please read the following
notes for the different temperature ranges.
Engine cold
If the LEDs are still in the lower range of the dis­
play, this indicates that the engine has not yet
reached operating temperature. Avoid high en­
gine speeds, full acceleration and heavy engine

loads.

Normal temperature
The LEDs will settle somewhere in the centre of
the display once the engine has reached operat­
ing temperature. If the warning lamp || lights
up in the instrument cluster display, the coolant
temperature is too high
<^>page
30.
© CAUTIO
- Additional lights and other accessories in
front of the air inlet reduce the cooling ef­
fect of the radiator. At high outside temper­
atures and high engine loads, there is a risk
of the engine overheating.
- The front spoiler also ensures proper distri­
bution of the cooling air when the vehicle is

moving.
If the spoiler is damaged this can
reduce the cooling effect, which could cause
the engine to overheat. Obtain professional
assistance.
® Note
Applies to: vehicles with diesel engine
These engines are so efficient that they may
not reach their full operating temperature in
very cold weather. This is quite normal and no
cause for concern.
Rev counter

The
rev counter indicates the number of engine
revolutions per minute.
The start of the red zone on the dial indicates the
maximum engine speed which may be used brief­
ly in all gears when the engine is warm and after
it has been run in properly. However, it is advisa­
ble to change up a gear or move the selector lev­
er to D/S (or
lift your
foot
off
the accelerator) be­
fore the needle reaches the red zone. •

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:

|MENU|
button
>
Car
>
left control button
>
A/C.
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:
|MENU|
button >
Car
>

>
Auto supple­
mentary heater.
® For the sake of the environment
I

- Switch off the cooling mode on the air
con­

ditioner* by pressing the A/C button if you
wish to save
fuel.
This will also reduce emis­

sions.
The LED in the button will go out
when the air conditioner is switched off.
- On vehicles with efficiency program*, you
can see how your fuel consumption is being
affected by auxiliary equipment and have
tips for improved fuel economy displayed

- Applies to vehicles with diesel engine: The
automatic supplementary heater function
can be switched off on the infotainment sys­
tem
cépage
66, Supplementary
heater*.

©
- 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.

trols.
The LED in the corresponding button lights
up when the function is switched on.
Manual air conditioner*
For
a
comfortable climate inside the vehicle us­
ing the air conditioner:
- In the summer, adjust the temperature to just
a few degrees below the outside temperature
- Do not turn the blower up too high
- Do not point the air outlets directly at the occu­
pants
A/C Cooling mode*
The air cooling system only works when the blow­
er is switched on. The air cooling mode is switch­
ed on/off when the A/C button is pressed. When
the air cooling is switched off, the air is not
cooled and therefore not dehumidified. The
win­

dows may mist up as a result. The air cooling is
switched off automatically at low outside
tem­

peratures.

Blower
You can adjust the blower speed manually using

control®.
You should leave the blower on at a
low setting to prevent the windows from misting
up and to ensure that the vehicle interior is
con­

stantly ventilated. To demist the windows, we
recommend
that
you increase the blower speed
and set control ® to

usually provides a comfortable environment.
At the
^
setting, the windscreen and side
win­

dows are defrosted or demisted as quickly as pos­

sible.
The air recirculation is switched off, but can
be switched on again manually by pressing the

button.
The round air outlets in the dashboard can be ad­
justed
^page

Automatic air conditioner
The air conditioner is fully automatic, and will
maintain the desired temperature at a constant

level.
When the heater is on, the blower normally
only switches to a higher speed once the coolant
has warmed up sufficiently (this does not apply
to the defrost setting).
AUTO Automatic or "eco" mode*
The automatic mode maintains a constant
tem­

perature inside the vehicle. Air temperature, out­
put and distribution are regulated automatically.
The AUTO mode is switched off immediately
when you operate any of the manual air controls.
The "eco"
mode*1*
is activated if you press the
AUTO button briefly while automatic mode is ac­

tive.
Fuel is saved in "eco" mode* because the
settings respond more passively. The "eco"

mode*
is on when eco appears in the console dis­
play. The "eco" mode* is deactivated when you
press the AUTO button again.

This function is not available on all export versions.
A/C Cooling mode
The air cooling system only works when the blow­
er is switched on. The air cooling mode is switch­
ed on/off when the A/C button is pressed. When
the air cooling is switched off, the air is not
cooled and therefore not dehumidified. The
win­

dows may mist up as a result. The air cooling is
switched off automatically at low outside

#
/ # Temperature
The temperature for the driver's and front pas­
senger's sides can be set separately using
con­

trols ® and @. The temperature can be adjusted
between +16 °C (+60 °F) and +28 °C (+84 °F).
Outside this range, LO or HI will appear on the air
conditioner display. In the two extreme settings
the air conditioner operates continuously with
maximum cooling or heating output, and the
temperature is not regulated automatically.
Synchronisation: By pressing the AUTO button
for 2 seconds, the temperature of the passeng­
er's side can be set to the temperature of the
driver's side. The settings remain synchronised
until the temperature is changed on the passeng­
er's side.
