in the passenger compartment at a low
level when the convertible top is open, this
enabling pleasant driving even at higher

luggage compartment when it is not
needed.

Adjustments
Sitting safely
The ideal sitting position can make a vital
contribution to relaxed, fatigue-free driving.
The sitting position also plays an important
role together with the safety belts and air-
bags in providing occupants with maximum
levels of passive safety in an accident. To
ensure that the safety systems operate with
optimal efficiency, we strongly urge you to
observe the instructions contained in the
following section.
For additional information on transporting
children safely, refer to page 51.
Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the air-
bags. Always hold the steering wheel by
its rim with hands at the 9 o'clock and
3 o'clock positions, to minimize the risk of
injuries to your hands and arms in the event
of airbag deployment.
No one and nothing is to come between the
airbags and the seat occupant.
Do not use the cover of the front airbag on
the front passenger side as a storage area.
Make sure that the front passenger is sit-
ting correctly and does not rest feet or legs
on the instrument panel, otherwise leg inju-
ries can occur if the knee and front airbags
are triggered.
Never let an occupant's head rest near or
on a side airbag because the inflating air-
bag could cause a serious or fatal injury.<
Even if you adhere to all the instructions
injuries resulting from contact with airbags
cannot be fully excluded, depending on the
circumstances. The ignition and inflation
noise may provoke a mild – usually tempo-
rary – hearing loss in extremely sensitive
individuals.
For airbag locations and additional infor-
mation on airbags, refer to page 81.
Sitting safely with safety belts
Fasten your safety belt before starting any
trip. Airbags complement the safety belt as
an additional safety device, but they do not
represent a substitute.
Your vehicle has four seats that are all
equipped with a safety belt.
At all times, occupants should sit
upright and be properly restrained:
infants and small children in appropriate
child-restraint systems; larger children and
adults using the safety belts.
Never allow more than one person to wear
a single safety belt. Never allow infants or
small children to ride in a passenger's lap.
Expectant mothers should always wear
their safety belts, taking care to position
the lap belt against the lower hips, where it
will not exert pressure against the abdomi-
nal area.
Do not route the belt across your neck, or
run it across sharp edges. Be sure that the
belt does not become caught or jammed.
Avoid twisting the belt while routing it firmly
across the hips and shoulder. Do not allow
the belt to rest against hard or fragile
objects. Otherwise, in the event of a frontal
impact, a loose lap belt could slide over
your hips, leading to abdominal injury.
Avoid wearing clothing that prevents the
belt from fitting properly and pull the lap
belt periodically to readjust the tension
across your shoulder in order to avoid a
reduction in the retention effect of the
safety belt.<
For instructions on operating safety belts,
refer to page 47.

Transporting children safely

Child seat security
All of the rear belt retractors and the front
passenger's safety belt can be locked for
mounting and securing child-restraint sys-
tems.
Information regarding this is located near
the buckle latch of each safety belt.
To lock safety belt
Pull the entire length of the belt from the
belt retractor. Allow the reel to retract the
belt somewhat and engage the buckle,
then tighten the belt against the child-
restraint system. The retraction mechanism
is now locked.
To unlock safety belt
Release the buckle, remove the child-
restraint system and allow the belt retractor
to reel the belt completely in.
Coupe: child-restraint system with
tether strap
If you use a child-restraint system with a
tether strap, two additional tether anchor-
age points have been provided – refer to
the arrows in the illustration. Depending on
the location selected for sitting in the rear
passenger area, attach the tether strap to the corresponding anchorage point to
secure the child-restraint system, as
shown in the illustration below.
Each sitting position is fitted with a head
restraint.
The head restraint must be adjusted into
the lowest possible position. Pass the
tether strap over the head restraint.
Adjust the tether strap according to
the child-restraint manufacturer's
instructions.<
LATCH child-restraint fixing
LATCH: Lower Anchor and Tethers for
CHildren.
The rear outer sitting positions are pro-
vided with anchors for a LATCH child-
restraint fixing.
To fit the LATCH child-restraint fixing,
follow the operating and safety
instructions of the system manufacturer.<
Access to anchorage points
The illustrations show the right rear seat as
an example. The outer anchorage points
for the LATCH child-restraint fixing are
identified by flags.

3 Start engine
Starting engine
Do not run the engine in closed
rooms, as otherwise the inhaling of
toxic exhaust gases can cause uncon-
sciousness and death. The exhaust gases
contain carbon monoxide, an odorless and
colorless, but highly toxic gas.Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.
To prevent the vehicle from rolling, always
select idle position or position N and apply
the handbrake before leaving the vehicle
with the engine running.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by
leaving it running while the vehicle remains
stationary. Instead, begin to drive immedi-
ately at a moderate engine speed.
Special starting conditions
Press the accelerator pedal halfway down
when starting if
>the engine fails to start on the first
attempt, for instance, if it is very hot or
cold
>the engine is started at very low tem-
peratures, below approx. + 57/–156,
at high altitudes, over 3,300 ft/1,000 m.
Avoid frequent starting in quick suc-
cession or repeated start attempts in
which the engine does not start. Otherwise,
the fuel is not burned or inadequately
burned and there is a danger of overheat-
ing and damaging the catalytic converter.<
Manual transmission
1.Apply the handbrake
2.Gearshift lever in idle position
3.Press the clutch pedal
If the clutch pedal is not
depressed, the engine will not
start.<
4.Start the engine.
Do not terminate the starting operation
too early, but after approx. 20 seconds
at the latest. When the engine starts, let
go of the ignition key immediately.
