Folding top
Folding top
Folding top
General
The comprehensively engineered design of the fabric folding top
allows it to be operated quickly and simply. When open, the folding
top is stowed completely in a tonneau provided specifically for this
purpose.
In normal operating conditions, the folding top is wind -and water ­
proof. Under certain circumstances, a small quantity of droplets might form, but only in extremely inclement weather, e.g. torrential
or continuous heavy rain. This is normal and not a cause for
concern .
Follow the care instructions =>
page 203, "Folding top care" to main ­
tain the folding top's attractive appearance and to keep it wind- and
waterproof. Please follow these instructions as well:
• Stow and open the folding top only when it is clean . When the
top is folded away, sharp -edged contaminants can build up as silt
and cause wear spots on the rear window, which may damage the
folding top over time. Of course, ice and snow should also be
removed before opening the folding top.
• Under no circumstances should you use sharp -edged or abrasive
objects to remove ice and snow. Use a commercial ice scraper to
remove ice from of the rear window.
• The folding top should be opened only if it is completely dry . If
the folding top is opened and then stored wet, unattractive indenta ­
tions may develop. In addition, over time, mold and mildew stains
can develop.
• Do not leave the folding top open for several weeks at a time;
instead, open and close it from time to time so that the fabric does
not discolor where it folds, and to prevent creases from forming. This is especially
important if it happens to be stowed while still
damp on occasion.
• Because the fabric becomes less flexible when temperatures
drops below zero, we recommend not operating the folding top
below0°C.
& WARNING
• When operating the folding top, make sure that any external
factors {e.g. the wind) do not impair its function or endanger other
drivers.
• Never drive while the folding top is not properly secured. Other­
wise, it may be pulled open by the wind. This can cause injuries
and damage to the vehicle -danger of an accident!
• When opening and closing the folding top make sure to keep
yourself and others clear of all moving parts. Risk of injury!
0 Note
• Always make sure that there is enough clearance above the
vehicle so that the folding top is not damaged when opening and
closing.
• Do not place any objects in the tonneau to avoid damage when
opening the folding top.
[ i] Tips
• The folding top should be operated only with the ignition
switched on.
• When parking the car with the folding top open, bear in mind
that the vehicle's interior is not protected from damage due to unex­ pected weather conditions, or unauthorized access. It is therefore
advisable to close the folding top before leaving the vehicle. If

Con tro ls and eq uip­
ment
Clear vision
The headlights only work when the ignition is switched on . While
starting the engine or when switching off the ignition, the head ­
lights will go off and only the side marker lights will remain lit .
& WARNING
Crashe s can happen when you cannot see the road ahead and
when you c annot be seen by other motori sts.
• Always tu rn on the headlight s so th at you can see ahead and
so that others can see your ca r from the ba ck.
[ i ] Tips
• I f you remove the ignition from the ignition lock wh ile the head ­
lights are still on, a buzzer will sound as long as the driver's doo r is
open to remind you to switch off the lights .
• Always observe the spec ific local regulations for your area when
to use your lights .
• I n coo l or damp weather conditions the headlights may fog over
tempo ra rily on the inside .
- The critical factor is the t emperature diff erence between the
interior and the ex te rior of the headlight lens .
- With the main beams switched on, the light -emitting area will
be free o f condensation after a short time, however the edges of
the glass may still be fogged .
- The rear lights and turn signa ls may also be affected.
- This physical phenomenon has no effect on the life of your
vehicle 's lighting system. •

Turn signals -¢ ¢ and high beam ~D lever
The lever on the left side of the steering column is used to
operate the turn signals and the high beam as well as the
headlight flasher.
Fig. 69 Turn signa l and
high beam leve r
The turn signal and high beam lever has the following func ­
tions:
Turn signals ¢ Q
- Lift the lever up all the way ~ fig. 69, to use the right turn
signals, or push the lever down all the way to use the left
turn signals .
Auto-blink
-Move the lever (up or down) just to the point of resis ­
tance to use the turn signals for as long as you need
them, for example when changing lanes. - Briefly
move the lever up or down just to the point of
resistance and then release it to flash the turn signals
three times in succession. This feature allows to indicate
lane changes clearly and with minimum effort when
driving on highways.
High beam [D
- Push the lever forward to switch on the high beam.
- Pull the lever back towards you to switch off the high
beam.
Headlight flasher [D
- Pull the lever toward the steering wheel to use the head­
light flasher.
Notes on these features
• The turn signals only work with the ignition switched on . The
indicator lights ¢ or¢ in the instrument cluster => page 16 also
blink .
• After you have turned a corner, the turn signal switches off auto ­
matically.
• The high beam works only when the head lights are on . The indi­
cator light ~D in the instrument cluster i lluminates when the high
beams are on.
• The headlight flasher works only as long as you hold the lever -
even if there are no lights switched on. The ind icator light ~D in the
instrument cluster illuminates when you use the headlight flasher .
0 Note
Do not use the high beam or headlight flasher if you know that these
could be blinding oncoming traffic. •

Wiper and washer system
Windshield wiper ~
The windshield wiper lever controls both the windshield
wipers and the washer system.
Fig. 72 Wiper lever:
windshield wiper lever
positions
T he windshield wiper lever :::::> fig. 72 has the following posi­
tions:
One -touch wiping
Move the lever to position G), when you want to wipe the
windshield
briefly.
Intermittent wiping ~ l (activating rain sensor)*
Move the lever up to position 0-
- Move the interval set switch@, to change the inter vals .
Low wiper speed
-Move the lever up to position ©-
High wiper speed
- Move the lever up to position @.
Automatic wiper/washer
- Pull the lever to position© (toward the steering wheel)
and hold.
- Re lease the lever . The washer stops and the wipers keep
going for about four seconds .
Turning off the wipers
-Move the lever back to position @.
The windshield wipers and washer only work when the ignition is
turned on. If you switch off the ignition with th e windshield wiper
lever still in the interval wipe position and then come back a while
later and drive off, the rain sensor will reactivate itse lf after the
vehic le speed has exceeded 4 mph (6 km/h).
The rain sensor* is only activated with the wiper lever set to posi­
tion
G) . When it starts to rain, the rain sensor will automatically acti ­
vate the intermittent wiping mode.
To reduce the sensitivity of the sensor , move switch
@ down . To
increase the sensitivity , move the switch up. The higher you adjust
the sensi tivity, the faster the sensor will react when it senses mois­
ture on the windshield. The pauses between wiper turns depend not
only on the sensitivity setting , but on the vehicle speed as well.
During brief stops , e.g. at a r ed light, wiper mot ion wil l automati ­
cally be reduced to the next lower speed. Wipers a lready turning at
low speed . change to intermittent wip ing.
When the igni tion is turned on, the washer jets are heated.
& 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~
