Convertible top
Convertible top
General information
The comprehensively engin eered design of the
f abric convertib le top a llows it to be operated
qu ickly and simply. When open, the convert i­
b le top is stowed completely in a tonneau pro­
vided spec ifically for this purpose.
I n normal operating conditions, the converti­
b le top is wind -and waterp roof. Under certa in
circumstances, a small quantity o f droplets
might form, but on ly in extremely inclement
weather, e.g . torrentia l or contin uous heavy
rain. This is normal and not a cause for con­
cern.
F ollow the care instructions
Q page 155 to
maintain the convertible top's attractive ap­
pearance and to keep it wind- and waterproof.
Please follow these instructions as well:
- Stow and open the convertib le top only
when it is clean. When the top is folded
away, sharp-edged contaminants can build
up as silt and cause wear spots o n the rear
window, which may damage the convertible
top over time. Of course, ice and snow should also be removed before open ing the
convertible top.
- Under no c ircumstances should you use
sharp-edged or abrasive objects to remove
ice and snow . Use a commerc ial ice scraper
to remove ice from o f the rear window.
- T he convert ible top should be opened only if
it is complete ly d ry. If the convertib le top is
opened and then stored wet, unattractive
indentations may develop . In addition, over
time, mold and mildew stains can develop.
- Do no t leave the convertible top open for
several weeks at a time; instead, open and
close it from time to time so that the fabric
does not disco lor where it folds, and to pre­
vent creases from forming. This is espec ially
important if it happens to be stowed wh ile
still damp on occasion.
- Because the fabric becomes less flexible
when temperatures drops below zero, we
Convertible top 41
recommend not operating the convertible
top below O°C.
A WARNING -
- When operat ing the convertible top,
make sure that any external factors (e.g.
the wind) do not impair its funct ion or
e ndanger other drivers.
- Never drive wh ile the convertib le top is
not properly secured. Otherwise , it may
be pulled open by the wind. This can
cause injur ies and damage to the vehicle
- danger of an accident!
- When opening and closing the converti-
ble top make sure to keep yourself and
o thers clear of a ll movi ng pa rts. Risk of
in jur y!
d) Note
-Always make su re that there is enough
clearance above the veh icle so that the
c onvertib le top is not damaged when
opening and clos ing.
- Do not place any objects in the tonneau
t o avoid damage when open ing the con­
ver tible top.
(D Tips
- Th e convert ible top should be operated
only wi th the ign ition sw itched on.
- When pa rking the ca r with the convert i­
ble top open, bear in mind t hat the vehi­
cle's in terior is not p rotec ted fro m dam­
age due to unexpec ted weather condi­
tions, o r unauthorized access . It is there ­
fore advisab le to close the convertib le
top before leaving the veh icle. If objects
are left inside the vehicle, they should be
locked in the luggage compartment.

Adaptive light *
The benefit of adaptive l ight is that the curve
and the edge of the road are better i llum inat­
ed . The adaptive light is contro lled automati­
cally, depending on vehicle speed and steering
wheel angle.
When driving a round bends, the head lights
are contro lled according to steering wheel an­
g le . So that there is no black area ahead of the
ve hic le, the two main beams pivot at different
angles. The system works above a speed of
about 6 mph (10 km/h).

when leaving the car parked close to other
vehicles. ..,,.

_& WARNING
- Curved (i. e. convex) mirror surfaces in­
crease your field of view. Remember that
vehicles or other objects will appear
smaller and farther away than when seen
in a flat mirror.
If you use this mirror to
estimate distances of following vehicles
when changing lanes, you could estimate
incorrectly and cause an accident.
CD Note
- If the mirror housing is moved uninten­
tionally (for example, while parking your
vehicle), then you must first fold the mir­ ror electrically. Do not readjust the mir­
ror housing manually. You could damage
the motor which controls the mirror .
- If you wash the vehicle in an automatic
car wash, you must fold the exterior mir­
rors in to reduce the risk of damage to
the mirrors . Never fold power folding ex­
terior mirrors* by hand. Only fold them in and out using the power controls .

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 ¢

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

60 Seats and stor age
Seats and storage
General recommen­
dations
Why is your seat adjustment so
important?
The safety belts and the airbag system can
only provide maximum protection if the front
seats are correctly adjusted.
There are various ways of adjusting the front
seats to provide safe and comfortable support
for the driver and the front passenger. Adjust
you r seat prope rly so that :
- you can easily and quickly reach all the
switches and controls in the instrument
panel
-your body is properly supported thus reduc­
ing physical stress and fatigue
- the safety be lts and airbag system can offer
maximum protection
¢ page 109.
In the following sections, you will see exactly
how you can best adjust your seats .
There are special regulations and instructions
for installing a child safety seat on the front
passenger's seat. Always heed the informa­
tion regarding child safety provided in
¢ page 130, Child Safety.
A WARNING
Incorrect seating position of the driver and
all other passengers can result in serious
personal injury.
- Always keep your feet on the floor when
the vehicle is in motion -never put your
feet on top of the instrument panel, out
of the window or on top of the seat cush­
ion! This applies especially to the passen­
gers .
If your seating position is incorrect
you increase the risk of injury in the case
of sudden braking or an acc ident.
If the
airbag inflates and the seating position
is incorrect this could result in personal
injury or even death.
- It is important for both the driver and
front passenger to keep a distance of at least 10
inches (25 cm) between them­
selves and the steering wheel and/or in­
strument panel. If you're sitting any
closer than this, the airbag system can­ not protect you properly . In addition to
this, the front seats and head restraints
must be adjusted to your body height so
that they can give you maximum protec­
tion.
- Always try to keep as much distance as
possible between yourself and the steer­
ing wheel or instrument panel.
- Do not adjust the driver's or front pas­
senger's seat whi le the vehicle is moving.
Your seat may move unexpectedly, caus­
ing sudden loss of vehicle control and
personal injury. If you adjust your seat
while the vehicle is moving, you are out of position.
Driver's seat
The correct seat position is important for safe
and relaxed driving.
We recommend that you adjust the driver's
seat in the following manner :
.,. Adjust the seat in fore and aft direction so
that you can easily push the peda ls to the
floor whi le keeping your knee slightly bent
i::> A in Why is your seat adjustment so im­
portant? on page 60 .
.,. Adjust the seatback so that when you sit
with your back against the seatback , you can
still grasp the top of the steering wheel.
.,. Position the head restraint according to the
occupant 's height
<=:> page 63 . For maxi­
mum protection, the top of the head re­
straint shou ld be at least at eye level, pref­
erably higher and ideally level with the top
of the head
¢ page 95, fig. 102.
A WARNING "--
Never place any objects in the driver's foot-
well. An object could get into the pedal
area and interfere with pedal function. In
case of sudden braking or an accident, you
would not be able to brake or accelerate!
