Warm and cold Climate control system
Description
The climate control system warms , cools and re­
moves humidity from the air in the vehicle inte ri­
or. It is the most effective when the w indows and
sunroof* are closed . If there is a bu ild -up of heat
inside the ve hicle, ventilation can he lp to speed
up the cooling process.
I n all he ating mode f unct ions except for
defrost ,
the blower on ly switches to a higher speed once
the engine coolant has reached a sufficient tem ­
perature .
Pollutant filter
The pollutant filte r removes pollutants such as
d ust and pollen from the a ir.
Key recognition
The climate control settings are automatically
sto red and assig ned to the remote control key
that is i n use .
Warm and c old
@ For the sake of the environment
If you wo uld like to reduce fue l consumption,
switch the air conditioning off. T his w ill also
r educe em issions.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win ­
dows from fogging over, the a ir intake in
fro nt of the w indshie ld must be free of ice,
snow o r leaves .
- Condensation from the coo ling system can
dr ip and form a pudd le of water under the
veh icle . Th is is norma l and does not mean
t here is a lea k.
- The e nergy management system may tem­
pora rily switch off certa in functions, s uch as
the seat heati ng* o r rear window defogger .
Th ese sys tems are av ailable aga in as soon
as t he e nergy supply has been restore d.

system operates most efficiently in eco cooling
mode.
A/C MAX Cooling mode*
You can switch the maximum cooling mode on or
off using the rocker switch@. Th e air is not
cooled and humidity is not removed when coo ling
mode is switched off. This can cause fog on the
windows . Cooling mode switches off automati­
cally when the o utside temperature is below
ze ro. When the cooling mode is switched on, the
vehicle interior is cooled as quickly as possible
and dehumidified.
<::E::> Recirculation mode
In recirculation mode, the air inside the vehicle is
circu lated and fi ltered. This prevents the unfil­
tered air outside the vehicle from entering the
ve hicle interior . Switch ing recirculation mode on
when dr iv ing through a tunnel or when s itting in
traffic is recommended
~ ,&. .
You can switch the recircu lation mode on or off
using the
6<:> button . You can also sw itch the re­
circulation mode off by pressing the knob(!) or
the Sfx button.
AUTO automatic mode
Automatic mode ma inta ins a constant tempera­
ture ins ide the veh icle. Air temperature, airflow
and a ir distribution are controlled automatically .
You can switch automatic mode on or off by pressing the
knob @.
Temperature
You can adjust the temperature between 60°F
(+16°() and 84°F (+28°() by turn ing the knob
@. If outs ide of this range, LO or HI will appear
in the climate control system display. In both
sett ings, the climate control runs constantly at
the maximum cooling or heating level. The tem­
perature is not regulated.
The temperature can be adjusted in the rear us­
in g the rea r controls
~ fig . 83 .
<%'~ Blower
You can adjust the vo lume of air generated by the
blower to your preference using the rocker sw itch
@ . The blower should always run at a low setting
Warm and cold
to prevent the windows from fogging and to en ­
sure a continuous exchange of air inside the ve hi­
cle . To have the blower regulated a utomatica lly,
press one of the
knobs @.
Air distribution
You can use the rocker sw itches @to adjust the
vents where the air wi ll flow out o f. Press the
rocker switches @repeatedly until the desired
air distrib ution setting is disp layed in the climate
contro l system controls. To have the air distribu­
t ion regulated automat ically, press one of the
knobs @.
.JI~ Seat heating/ventilation*
Pressing the JI~ button switches the seat
heating/ventilation on at the highest setting
(level 3). The LEDs indicate the temperature lev­
el. To reduce the temperature, press the button
again. To switch the seat heat ing/ventilat ion off,
press the button repeatedly until the LED turns
off.
:.f% Defrosting
The w indshield and side windows are defrosted
or cleared of condensat ion as quickly as poss ible.
The maximum amount of a ir flows mainly from
the vents below the windsh ield. Rec ircu lat ion
mode switches off. The temperatu re should be
set at +72°F (+22°() or hig her. Th e temperature
is controlled automat ically.
You can switch the defroster on or off using the
3R button. You can switch the fu nction off by
pressing a
knob @.
[ffi) REAR Rear window defogger
You can switch the rear w indow defogger on by
pressing the
!!P. button . It only operates when the
engi ne is run ning .
It switches off automatically
after 10 to 20 minutes , depending on the outside
temperature.
T o prevent the rear window defogger from
switching off automat ically, press and hold the
QiP REAR button for more than thr ee seconds.
T his is stored until the ignition is switched off .

engaged, for examp le when you notice that the
next traffic light is red . This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt ion to zero (fuel shut-off during decelera­
tion) .
Shift effici entl y
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fue l unnecessari­
ly .
Press down on the acce lerator peda l slowly and
avoid "kick -down".
Avoid full acceleration
You shou ld rare ly t ravel at the maximum vehicle
speed. High speeds cause a d isp ropor tionately
high increase in fuel consumption, emissions and
traffic noise . Driving more slowly saves fue l.
Reduce idling time
The Start/Stop system* helps to reduce the idling
time automatically. In vehicles witho ut the Start/
Stop system* , it is
efficient to switch the eng ine
off when stopped at rai lroad crossings and long
red lights . Stopping the engine for
30 -40 sec ­
onds already saves more fu el than the amount of
extra fuel needed to restart the engine.
It t akes a very long time in idle to wa rm the en ­
gine up to operating temperature . Wear and
emissions are especially high in the warm -up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while do ing th is .
Ha ve mainten anc e performed regularly
By having maintenance performed regu lar ly on
your veh icle, you can he lp to reduc e fuel con­
sumpt ion before you even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long -term value but al­
so impacts fuel consumption . A poorly main­
tained engine can lead to fuel consumpt ion that
is
1 0% hi gher tha n normal.

Avoid short trip s
The engine and exh aust clean ing system mus t
reach their optima l operating temperature to ef­
fective ly reduce consumption and emissions.
A cold engine uses a d isp roportionately high
amoun t of fue l. The eng ine re aches opera ting
temperat ure and cons umption norma lizes on ly
after approximate ly 2.5 mi les (4 km) .
Check the tire pressure
To save fue l, ma ke sure the t ires are always in­
flated to the correct
press ure~ page 335. The
fuel consumpt ion can increase by
5% if the pres ­
sure is on ly
0 .5 bar too low. Due to t he increased
rolling resistance, low tire pressures wi ll also
l ead to greater tire wear and will affect driving
behavior.
Do not drive on winter tires year -round, as this
will consume up to
10% more fue l.
Eliminat e unnecessary weight
Since eve ry po und of ext ra weight increases f uel
consump tion, a quick inspec tion of the luggage
compartment may be worth it to avoid unneces ­
sary weight .
When not be ing used , a roof rack sho uld be re ­
moved to decrease the w ind resis tance of the ve­
hicle . This will save you approx imately
12% fue l
at speeds from
6 2 -75 mph (100 -120 km/h) .
Save energy
The eng ine d rives the generator, which generates
electr ic ity; the f uel consumpt ion also inc reases
wi th the demand for e lec tricity . T he refore, sw itch
electrica l eq uipment o ff when you no longe r
need it . Examples of eq uipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights s houl d come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
h eat, which could result in overheating or
other damage to the veh icle or othe r proper­
ty .
