Climate control system
Description
A pp lies to: ve hicles w ith 3 -zo ne del uxe automatic c limate
co ntrol or 4-zo ne de luxe au tomatic cl imate co ntrol
The climate control system warms, cools and re­
moves humidity from the air in the vehicle interi­
or.
It is the most effective when the windows and
sunroof* are closed . If there is a bu ild-up of heat
inside the vehicle, ventilat ion can he lp to speed
up the cooling process.
In all heating mode functions except for
defrost,
the blower on ly switches to a h igher speed once
the engine coolant has reached a suffic ient tem­
perature.
Pollut ant filt er
The pollutant filter removes pollutants such as
dust and pollen from the a ir .
K ey recognit ion
The climate control settings are automatically
stored and assigned to the remote control key
that is in use .

@ For the sake of the environment
- If you would like to reduce fuel consump­
t ion, sw itch the air conditioning off. This
will also reduce emissions.
- In vehicles with a diesel engine, you can
switch the auxiliary heater off in the Info­
tainment system.
(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
front of the windshield must be free of ice,
snow or leaves.
- Condensation from the cooling system can
dr ip and form a puddle of water under the
vehicle . This is normal and does not mean
there is a leak.
- The energy management system may tem­ porarily switch off certain functions, such as
the seat heating* or rear window defogger.
T hese systems are ava ilable again as soon
as the ene rgy supply has been restored.

When synchronization is switched on, the set­
tings for the driver's side are applied to the front
passenger's side and the rear (except for seat
heating/venti lation*). When the settings on the
front passenger's side or in the rear are changed,
the synchron izat ion is automatically switched off

mat ica lly after a ce rtain per iod of t ime or after
leav ing the menu.
Vents
You can open or close the center and rear vents in
the cockpit and the vents in the rear center con­
sole and door p illars using the r idged thumb­
wheels. The levers adjust the d irect io n of the a ir­
flow from the vents. The w ide vent is opened and

Residual heat
You can activate the residual heat function when
the ignition is switched off by pressing the knob
© (left side). The residual heat from the coolant
is used to heat the ve hicle in ter io r. The res id ual
heat function switches off automatically after
about 15 minutes.
A WARNING
- You should not use the recirculation mode
for an extended period of time, because no
fresh air is drawn in and the windows can
fog when cooling mode is sw itched off . This
i ncreases the risk of an accident .
- Individuals with reduced sensitivity to pain
or temperature could develop burns when
us ing the seat heating function . To reduce
the risk of injury, these ind iv iduals should
not use seat heat ing.

@ Note
To avoid damage to the heating elements in
the seats, do not knee l on the seats or p lace
heavy loads on a small area of the seat.

::r ' engaged, for example when you notice that t he
next traffic light is red . This produces an engine
b raking effect, wh ich he lps to protect the brakes
and tires and reduces the emissions and f uel con­
sumpt ion to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficientl y
Upshifting earlier is an effective way to save fue l.
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 sho uld rare ly t rave l at the maxim um vehicle
speed. High speeds cause a d isp roportiona tely
hi gh increase in fuel consump tion, emissions and
traffic noise . Driving more slowly saves f uel.
Reduce idling time
The Start/Stop system* he lps to reduce the id ling
time automatically. In vehicles wi thout the Sta rt/
Stop system*, it is efficient to switch the engine
off when stopped at ra ilroad crossings and long
red lights . Stopping the engine for
30 -40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine.
I t takes 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 .
Have maintenance perf ormed regularly
By having maintenance performed regu larly on
your ve hicle, you can he lp to reduce fuel con ­
sumpt ion before you even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l­
so impacts fuel consumption . A poorly main­
tained engine can lead to fuel consumpt ion that
i s
1 0% hi gher tha n normal.
Driving
Avoid short trips
T he eng ine and exh aust cleaning system mus t
r each their optima l operat ing temperatu re to ef ­
fectively reduce consumption and emissions.
A cold engine uses a d isp roportionately high
amoun t of fue l. The engine re ac h es operat ing
temperat ure and cons umption norma lizes on ly
after approximate ly 2.5 mi les (4 km) .
Check the tire pressure
To save fuel, ma ke sure the t ires are always i n­
flated to t he correct pressure~
page 340. The
fuel consumpt io n can increase by
5% if the pres ­
s u re is on ly
0 .5 bar too low. Due to the 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 fuel.
Eliminate unnecessary weight
S ince eve ry po und of ext ra weight increases f uel
co nsump tion , a quick inspect io n of the luggage
compartment may be worth it to avoid unneces ­
sary weight .
When not be ing used , a roof rac k sho uld be re­
moved to decrease the w ind resis tance of the ve ­
hicle . This will save you approximately
12% fu el
at speeds from
62 -75 mph (100 -120 km/h) .
Save energy
The eng ine d rives the generator, which generates
electric ity; the fuel consumpt io n also increases
wi th the dema nd for e lec tric ity . T he refore, sw itch
electrical eq uipment off when you no longer
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 sho uld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could resu lt in overheating or
other damage to the veh icle or other proper ­
ty .

A WARNING
To reduce the risk of poisoning, never allow

(LlJ) Note
Avoid high eng ine speed, full throttle, a nd

@ For the sake of the environment
Do not let the engine run while parked to

- If you leave the vehicle, sw itch the ignition

General info rmation
Traffic sign recognit ion can detect standa rd
speed limit sig ns that are within the camera's vis­
ua l field. With assistance from navigation data,
detected speed limits are evaluated and shown in
the disp lay . The traffic sign for the current de­
tected speed l imit will bli nk in the display if you
exceed the war ning th reshold set in the Infotain­
ment system

The traffic sign recogn ition is subject to certain
system limitations and may be unavailab le or on ­
ly partia lly available in the followi ng situations:
A ssi st a nce systems
- when visibility is poor, s uch as in snow, rain,
fog or heavy spray
- when there is glare, for example from oncom­

- at high speeds
- if the camera 's visual field

for examp le by dirt or st icke rs. For i nfo rmation
on cleaning, see

- if the traff ic signs are comp letely or partially
covered, for examp le by trees, snow, dirt or

- if traffic signs are damage d or ben t
- if traff ic sig ns are d isplayed o n sig n holders

P ay atten tion to traffic and the area around
your vehicle when traffic sign recogn ition is
turned on . The traffic signs insta lled on the

The driver is a lways responsible for assessing
the traffic situation.
- Under some circ umstances, traffic s ign rec­

rectly or detect them at a ll. As a resu lt, the
system may not dis play the correct speed lim it or any speed limit.
- Traffic sign recognit ion does not adapt your
veh icle's speed to match the speed limit!
- The display in the instrument cluster is
