For your own safety

Use unleaded gasoline only. Fuels
containing up to and including
10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight (i. e. 15 %
MTBE or 3 % methanol plus an equiva-
lent amount of co-solvent) will not void
the applicable warranties respecting
defects in materials or workmanship.
Field experience has indicated signifi-
cant differences in fuel quality (volatility,
composition, additives, others) among
gasolines offered for sale in the United
States and Canada. Use of inferior fuels
can lead to poor starting, drivability
problems and stalling; these difficulties
can be aggravated by extreme oper-
ating conditions such as those encoun-
tered in extremely hot weather and at
high altitudes.
Should you encounter driveability prob-
lems which you suspect could be
related to the fuel you are using, we
recommend that you respond by
switching to a recognized high-quality
brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Always observe all applicable safety
rules and precautions when handling
gasoline.

Cruise control You can store and automatically main-
tain any desired vehicle speed above
approx. 20 mph (30 km/h).
Refrain from using the cruise
control on twisting roads, when
high traffic density prevents driving at a
constant speed, and when driving on
slippery (snow, rain, ice) or loose
(gravel, sand) road surfaces.< 520de061
Store and maintain
speed/acceleratePress the lever briefly in direction 1:
The system maintains the current
vehicle speed. Every time you briefly
press the lever, the speed increases by
approx. 0.6 mph (1 km/h).
Press and hold the lever in position 1:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the lever, the system main-
tains the current speed.
The vehicle may accelerate
beyond the preselected speed on
steep downhill stretches, where engine
braking alone may not be enough to
slow the vehicle. It can also slow when
the engine fails to maintain the prese-
lected speed when ascending steep
grades.< To deceleratePress the lever briefly in direction 2:
With the cruise control active, the
speed decreases by approx. 0.6 mph
(1 km/h) every time you briefly touch the
lever.
Press and hold the lever in position 2:
With the cruise control active, the
system automatically reduces the
throttle opening to slow the vehicle.
When you release the lever, the system
registers and maintains the current
speed.To cancel the cruise controlPress the lever briefly in direction 3:
The cruise control is immediately
canceled.
In addition, the system automatically
deactivates in response to the following
conditions
>braking
>clutch disengagement
>when vehicle speed deviates from
the preset speed for an extended
period, for instance, as a result of
pressure on the accelerator pedal. To deactivate the system Turn ignition key to position 0.

Coolant temperature gauge Service Interval Display BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on in the course of
normal vehicle operation, the engine
has overheated. Turn it off immediately
and let it cool down.520de031
Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response
to high outside temperatures or severe
operating conditions.
For checking coolant level, refer to
page 111.
Remaining distance before
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The remaining distance in miles and the
next scheduled service will appear
together with the display OILSERVICE
or INSPECTION.
The computer bases its calculations
for the remaining distance on the
previous driving style.
A flashing display and a "Ð" in front of
the number indicate that service is past
due by the number of miles displayed.

Tire Pressure Warning (RDW)The conceptRDW monitors the tire pressure in all
four wheels while driving. The system
provides an alert whenever the inflation
pressure drops significantly in one of
the tires.
For RDW to "learn" the correct tire infla-
tion pressure, check the inflation pres-
sure in all tires, comparing them with
the values in the inflation pressure table
(refer to page 27), and make correc-
tions as necessary. Then activate the
system.
The indicator lamp within the in-
strument cluster flashes to alert
you to substantial pressure loss
in any of the tires.
To activate the system 1 Turn the ignition key to position 2
2 Press the switch long enough for
the indicator lamp in the instrument
cluster to light up red for a few
seconds
3 RDW carries out an automatic
initialization process while you are
driving, and stores this data to aim for
optimal conditions. This one-time
"learning" process lasts at least
10 minutes, after which the RDW is
able to detect and report a flat tire.520de117
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement.
Do not reactivate the system after
periodic corrections of inflation pres-
sures to maintain them at the levels
stored during an earlier initialization
process.

Heating and ventilation/Air conditionerAir supply
You can select blower speeds
from 1 to 4. The higher the
setting, the greater the
amount of heat and air supply.
In position 0, the blower, heating and air
conditioner are switched off.
Temperature
In order to increase the inte-
rior temperature, turn to the
right. For rapid heating, turn
completely to the right. Then
select an interior temperature that is
comfortable for you.
Air distribution
You can direct the airflow onto
the windows , toward the
upper body and into the
footwell . You can also make
all intermediate settings. The "6 o'clock"
setting is recommended for normal
conditions (refer also to the illustration
and overview on page 72).
Recirculated air mode
If there are unpleasant odors
in the incoming air, you can
temporarily block the air
supply. The system then recir-
culates the air already within the
vehicle.
If condensation starts to form on
window surfaces during opera-
tion in the recirculated-air mode, switch
it off and return the ventilation system
to the incoming air mode; turn up the
blower and select the defroster if
necessary to clear the windows.<
Incoming air mode
Recommended when driving
with the convertible top open.
The degree to which the
passenger compartment is
heated depends on temperature selec-
tion and air distribution.
Air conditioner/incoming air mode
The air is cooled and dehu-
midified and Ð depending on
the temperature setting Ð
warmed again when the air
conditioner is switched on. Depending
on the weather, the windshield may fog
over briefly when the engine is started.
Do not turn on the air conditioner if the
outside air temperature is below
approx. 41 7 (5 6). This will help to
prevent the windows from fogging.
If the windows fog over after switching
the air conditioner off, switch it back on.
Air conditioner/Recirculated air
mode
You may find it useful to acti-
vate both systems to cool the
car more rapidly after it has
been parked with the top up
on a hot day. This setting provides the
coldest possible airflow from the vent
outlets (with temperature selection
switch turned all the way to the left).
