During brief stops, e.g. at a red light, wiper
motion will automatically be reduced to the
next lower speed. Wipers already turning at
low speed change to intermittent wiping.
When the ignition is turned on, the washer
jets are heated.
A WARNING
- Wiper blades are crucial for safe driving!
Only when they are in good condition are
they able to clear the windows properly
to provide uncompromising visibility .
Worn or damaged wiper blades are a safety hazard ¢
page 5 7, Replacing
windshield wiper blades!
- The light/rain sensor* is only designed to
assist and support the driver.
It remains
entirely the driver's responsibility to
monitor outside weather conditions and
to manually activate the wipers as soon as rain or drizzle reduces visibility
through the windshield.
- The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter .
(I) Note
In freezing or near freezing conditions:
- Always check that the wiper blades are
not frozen to the glass before you turn
the wipers on . Loosen a wiper blade
which is frozen in place before operating
the wipers to prevent damage to the
wiper blade or the wiper motor.
- Do not use the wipers to clear a frosted window . Using the wipers as a conven­
ient ice scraper will destroy the wiper
blades.
- Before you take your vehicle to an auto­
matic car wash, make sure you have the
windshield wiper system switched off (lever in position 0), otherwise the wind­
shield wiper system could get damaged

in the car wash if it should suddenly
come on.
(0 Tips
- The windshield wipers are switched off
when the ignition is turned off. Activate
the windshield wipers after the ignition
is switched back on by moving the wind­
shield wiper lever to any position.
- Worn or dirty windshield wiper blades
cause smearing, which can affect the op­
eration of the light/rain sensor* . Check
the condition of your windshield wiper
blades regularly.
- The rain sensor is part of the interval
wiping system . Turning off the ignition
will also deactivate the rain sensor. To re­ activate the sensor, switch off the inter­
val wiping function, then switch it back
on again.
-Applies to vehicles with light/rain sen­
sor : When the wipers are switched on
manually and in rain conditions, the au­
tomatic headlights* turn on¢

Warm and cold Climate controls
Controls
W arm and cold 6 7
The air conditioning automatically maintains the selected temperature in the vehicle interior
throughout each season .
Fig. 78 Climate contro ls
We recommend the following sett ing :
• Rotate the knob
c::> fig. 78 @ to the right to
switch on the air conditioning .
• Set the temperature to 72 °F (22 °() .
• Press the
!AUTO I c::> fig . 78 button .
Using the previously recommended setting is
the quickest way to achieve a comfortable cli ­
mate in the vehicle . Th is setting should there­
fore only be changed when persona l comfort
l eve ls o r certain circumstances requ ire it .
The climate controls are a combination of au ­
tomatic heating and ventilation systems and a
coo ling system which dehum idifies and coo ls
the air inside the vehicle .
The climate controls automatically maintain a temperature once it has been set. The tem­pe rat ure of the air from the v ents, fan speed
(air vo lume) and ai r distribu tion are also auto ­
mat ica lly adjusted . The system also takes into
account strong sunshine so that manua l ad ­
justment is not necessary . So in almost all
cases,
a utomatic mode offers the best cond i­
tions for the comfort of the occupants at all
times of the year
c::> page 70 .
Plea se note:
In cooling mode, relative humidity in the inte­
rior is reduced . This prevents the w indows
from fogg ing up .
When relative hum idity and temperatures
outside are high,
condensation can drip from
the a ir cond ition ing evaporator and form a
poo l of water under the veh icle. This is normal
and not an ind ication of a leak!
When outside temperatures are low, the fan
does not switch to a higher speed until the coolant has reached an adequate tempera ­
tu re , with the exception of the defrost set­
t ing.
When accelerating at wide-open throttle, the
air condit ioning compressor is temporar ily
switched off to maintain full engine power.
In order to ensure engine cooling under ex­
treme engine loads, the compressor is switch­
ed off if coolant temperatures cl imb too high .
Funct ions are set by turn ing the rotary knob
or switched o n and off by tapp ing the buttons.

The rear window defogger works only when
the engine is running. The indicator light in
the button illuminates when the rear w indow
defogger is turned on .
The rear window defogger is switched off au­
tomatically after approx . 10 minutes .
@) For the sake of the environment
As soon as the rear window is clear, yo u
should switch the rear window de fogger
off . The reduced power consumption has a
beneficial effect on fuel consumption.

A WARNING
Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heating function. To reduce
the risk of inju ry, these individuals should
not use seat heat ing .
