Retractable hardtop
The retractable hardtop combines reliable
weather protection with simple and convenient
operation.
Please note:
> It is advisable that yo u close the retractable
hardtop when you park the vehicle. Not only
does the closed hardtop protect the vehicle
interior against unanticipated weather dam-
age, it also offers theft protection. However,
even when the hardtop is closed, valuables
should only be stored in the locked
cargo bay.
> Do not attach roof rack systems to the
retractable hardtop, and in particular do not
attach magnetic racks.
> Do not attach rack sy stems to the luggage
compartment lid, and in particular do not
attach magnetic racks.
> When the retractable hardtop is operated,
the luggage compartment lid swings back
and up. Before operat ing the retractable
hardtop, ensure that there is enough clear-
ance, e.g. in tight parking spaces.
> If you open the hardtop while it is wet, e.g.
after driving in the rain, water may drip into
the cargo bay. If necessary, remove items
from the cargo bay beforehand to avoid
water stains or soiling.
Do not place any objects on the retract-
able hardtop or on the luggage compart-
ment lid, otherwise they could fall during move-
ments of the retracta ble hardtop and cause
damage or injury.
Driving when the hardtop is not fully opened or
not fully closed may result in damage or injury.
Do not reach into th e mechanism while the
hardtop is opening or closing. Keep children
away from the swiveling area of the retractable
hardtop. <
The retractabl e hardtop cannot be moved
at temperatures below + 14 7/–10 6. A
message appears on the Control Display. top can only be
opened and closed when the vehicle is
stationary. To avoid causing damage, do not
drive off until the hardtop has stopped
moving. <
Before opening and closing
Do not let the hardtop stop in an interme-
diate position when opening or closing.
Otherwise, there is the danger of personal injury
since the hardtop will be lowered automatically
after a few minutes. <
> Comply with the safety precautions
described above.
> Ensure that the luggage compartment lid is
closed.
> The vehicle should be pa rked on fairly level
ground. Excessive angle is indicated by
alamp.
> Fold down the cargo bay partition and make
sure it engages, refer to the instructions
below.
> Do not place any object s next to or on the
cargo bay partition and close the storage
compartment on the left side of the
cargo bay.
> Do not exceed the maximum loading height
under the cargo bay partition; refer to the
label in the cargo bay showing a line indicat-
ing the maximum height.
Folding down the cargo bay partition

Lateral storage compartment behind
the seats
This space can be used to store briefcases, for
example.
When loading the rear storage shelf, do
not move both seats all the way forward
while moving them to th eir uppermost position
and leaning the backrests forward. Otherwise,
the seats could hit and damage the seal on the
windshield and the sun visor.
Only transport light and small objects in the lat-
eral storage compartment; otherwise, braking
maneuvers and swerving may lead to a safety
hazard due to objects flying about the passen-
ger compartment. Only transport heavy lug-
gage in the cargo bay if it has been appropri-
ately secured. <
Cup holders*
Use lightweight and shatterproof contain-
ers and do not transp ort hot beverages,
otherwise there is an increased risk of injury in
the event of the accident. Do not force contain-
ers that are too large in to the cup holders, oth-
erwise damage could result. <
In the center armrest
The cup holders are located the center console.
Attachable cup holder*
Attaching to the center console
Mount the cup holder onto the center console
so that it snaps into place.
Storing in the glove compartment
Insert the cup holder into the holder in the glove
compartment.

Things to remember when driving
110
Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4,500 rpm or a
road speed of 100 mph/160 km/h.
Do not drive with full-throttle operation, and do
not use the transmission 's kick-down mode or
Launch Control.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do no t achieve their full trac-
tion potential until afte r an initial break-in
period. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clut ch reaches its optimal
level only after a distan ce driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewe d in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicle serviced regularly.
Remove any unneeded cargo
Additional weight incr eases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove additional mirrors and the luggage rack
when they are no longer in use. Mounted parts
affect the vehicle's aerodynamics and increase
fuel consumption.
Close both windows
An open glass roof or window causes higher air
resistance and thus increases fuel con-
sumption.
Check tire inflation pressure regularly
Check the tire inflation pr essure at least twice a
month and before embarking on a long journey,
and correct it if necessary.
Low tire inflation pressure causes higher rolling
resistance and thus increases fuel consumption
and tire wear.
Set off immediately
Do not let the engine wa rm up while the car is
still standing, but set off immediately at moder-
ate engine speed. This is the fastest way for the
cold engine to reach its operating temperature.
