ing damage to the windshie ld wiper system .
(D Tips
-The windshield wipers switch off when the
ignition is switched off . You can activate the
windshield wipers after the ignition is switched back on by moving the windsh ield
wiper lever to any posit ion.
- Worn or dirty windshield wiper blades result
in streaking. This can affect the rain sensor
funct ion. Check your windshield wiper
blades regularly.
- The washer fluid nozzles for the windshie ld
washer system are heated at low tempera
tures when the ignition is on .
- When stopping temporarily, such as at a
traffic light, the speed of the windshield
wipers automatically reduces by one level.
Cleaning the wiper blades
Clean the wiper blades when you see wiper
strea ks. Use a soft clot h and a glass cleane r.

A WARNING
For safety reasons, the windshield wiper
blades should be replaced once or twice each
year.
@ Note
- Only fold the windshield wipers away when they are in the service position. Otherwise,
you risk damaging the paint on the hood or
the windshield w iper motor .
- You should not move your vehicle or operate
the w indshield wiper lever when the wiper
arms are folded away from the windshield.
The windshield wipe rs would move back in
to their original position and could damage
the hood and windshield.
- To reduce the risk of damage to the wiper
system, always loosen blades which are fro
zen to the windshield before operating the
wipers.
- To reduce the risk of damage to the wiper
blades, do not use gasoline, kerosene, paint
thinner, or other so lvents on or near the
wiper blades.
- To reduce the risk of damage to the wiper
arms or other components, do not attempt
to move the wipers by hand.
(D Tips
- You can also use the service position, for ex
ample, if you want to protect the windshield
from icing by using a cover.
- You cannot activate the service position
when the hood is open.

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.

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
