Onboard computerAverage fuel consumptionThe computer can calculate average
fuel consumption rates for two different
distances at the same time (simulta-
neous data for an entire journey and for
a single segment of it, for instance).
To start calculations for distance 1:
Press the keys in the sequence shown
in the diagram.
To start calculations for distance 2:
The procedure is the same as that for
the first distance, except you will press
CONSUM 2 for your selection.
The computer starts calculating fuel
consumption as soon as you start driv-
ing.
Data request:
Press the BC key and CONSUM 1 or 2.380us189
Estimated cruising rangeDisplays the estimated travel range
available with the remaining fuel. The
system calculates the cruising range
based on operating conditions and the
amount of fuel remaining in the tank.
The computer uses the average rate of
fuel consumption over the preceding
18 miles (30 kilometers) as a reference.
Data request:
Press the keys in the sequence shown
in the illustration.
A range of under 31 miles (50 kilome-
ters) is displayed in the Check Control
in the instrument cluster.380us180
Please respond to this warning by refu-
eling at once to avoid serious damage
to the engine and catalytic converter.
When you refuel, the onboard computer
registers the additional fuel only when
more than 1.5 gallons (5 liters) are
added.

Onboard computerAverage speedTo start calculations:
Press the keys in the sequence shown
in the illustration.
Calculations begin after you start off.
Data request: Press BC and SPEED
key.
The display shows your average speed
since the last time the SET key was
pressed. Calculations are interrupted
whenever you shut down the engine.
At speeds below 100 mph (100 km/h)
the display includes decimals.380us179
Distance remaining to destinationData request:
Press BC and DIST.
Displays the distance to the destination.
Available only if the total distance was
entered before the start of the journey.380us186
To enter the distancePress the keys in the sequence shown
in the illustration on the left.
The miles flash in the display.
Enter the distance with keys 0 – 9 and
confirm with the SET key.
Use the CLR key to make corrections.
Press once to delete the final digit.
Any additional mileage extending be-
yond the total defined in the initial entry
is indicated by a minus sign.380us187

Onboard computerEstimated time of arrivalData request:
Press the keys in the sequence shown
in the illustration.
Shows the estimated arrival time based
on current driving speed.
Functions only when you enter the trip
distance (DIST) before the start of the
journey.380us188
Speed warning threshold (Limit)Entry of a speed warning threshold
(Limit) will be indicated by the word
LIMIT at the right in the display.
Alerts you when you exceed the maxi-
mum speed that you entered earlier (for
instance, posted speed limit). Triggers
an acoustic signal, LIMIT flashes on the
right-hand side of the display, and the
stored limit appears in the instrument
cluster Check Control display panel for
approximately 3 seconds.
Vehicle speed must drop back to at
least 3 mph (5 km/h) below the pro-
grammed speed warning threshold to
reset the system for repeat warnings.380us181
To enter the speed warning
thresholdPress the keys in the sequence shown
in the illustration on the left.
The word MPH flashes in the display.
Enter the speed warning threshold with
the 0 – 9 keys and confirm with the SET
key.
Use the CLR key to make corrections.
Press once to delete the final digit.To deactivate the speed warning>Press BC and then press LIMIT twice.
The word LIMIT on the right side of the
display disappears, however the value
remains stored and can be reactivated
using the LIMIT key.To adopt the current speed
as the limitPress BC, LIMIT and SET twice.

Onboard computerCodeYou can program a code into the on-
board computer for supplementary pro-
tection against unauthorized attempts
to start the engine or tamper with the
vehicle. This feature provides you with
an extra measure of security extending
beyond that furnished by the vehicle im-
mobilization system (refer to page 31).
The system prevents the engine from
starting.
A code number is used to arm the sys-
tem. The code is then required for sub-
sequent starting attempts. Therefore:
Always remember the code number.
With the ignition key in position 1, press
the keys in the sequence shown in the
illustration.
"CODE – – – –" will appear in the dis-
play.380us687
Turn the ignition key to position 1
to set1 Use the 0 – 9 keys to enter the code
2 Press the SET key
3 Turn the ignition key to position 0 or
remove it.
If you press a different key of the on-
board computer before you turn the ig-
nition key to the 0 position, or if you turn
the key to position 2, the code which
has been entered will be deleted.
Code numbers from "0000" to "9999"
can be entered.
The code must be re-entered each time
the system is armed.
You can make corrections of the en-
tered numbers with the CLR key.380us688
To cancel with the ignition key at
position 1 or 2A gong and the "CODE – – – –" display
prompt the code entry.
1 Use the keys to enter the code
number
2 Press the SET key.
The system responds to attempts to
start the vehicle using an incorrect/no
code by preventing the engine from
starting.
The time automatically appears after
you enter the correct code and then
confirm it by pressing SET.
Three incorrect entries will cause the
alarm to sound for 30 seconds.

The rotary dials allow infinitely-vari-
able regulation of the air supply,
changes in the air-flow direction,
and temperature regulation.

rear passenger area with the levers
in the center of the vent). In the

Automatic climate controlTips for pleasant drivingUse the automatic system, i.e., press
AUTO button 4. Select an interior tem-
perature that is comfortable for you -
we recommend 707 (226) as a com-
fortable setting. When the outside tem-
perature is above 427 (56), you can
also use the air conditioning system 14.
This will dry the air and prevent window
fogging, for example if people are wear-
ing damp clothes in the vehicle. Set the
outlets 2 so that the air flows past you
and does not flow directly at you. Set
the rotary dial between the air outlets 2
for the upper body to a medium posi-
tion, since air that is somewhat cooler
promotes driving without fatigue.
The following description will guide you
through additional individual settings.
You can make the settings of your
vehicle in such a manner that,
when you unlock the car with your per-
sonalized remote control, your own per-
sonalized setting of the automatic cli-
mate control is initiated.<
Automatic air distribution
The AUTO program as-
sumes the adjustment of
the air distribution and the air supply for
you and in addition adapts the tempera-
ture to external influences (summer,
winter) to meet preferences you can
specify. This program maintains a com-
fortable in-car climate regardless of the
season. Select an interior temperature
that is comfortable for you - we recom-
mend 707 (226) as a comfortable
setting.
The temperature setting and the word
"AUTO" for the air flow appear in the
display 7 (refer to the overview on
page 100). Open the ventilation outlet
for the upper body area. Switch on the
air conditioner in warm weather. The
maximum cooling capacity is achieved
when you set the rotary dial 3 (refer to
page 104) to cold.
Individual air distribution
You can cancel the AUTO
program by selecting spe-
cific distribution patterns to
suit your own individual re-
quirements. You can direct
air to flow onto the windows , toward
the upper body , and into the footwell
.
To defrost windshield and door
windows
This program quickly removes
ice and condensation from the
windshield and the side windows.
Air conditioner
The air is cooled and dehumidi-
fied and - depending on the tem-
perature setting - warmed again when
the air conditioner system is switched
on.
Depending on the weather, the wind-
shield may fog over briefly when the en-
gine is started.
At outside temperatures below approx.
427 (56), switch off the air condi-
tioner. This will help to prevent the win-
dows from fogging up.
If the windows fog over immediately af-
ter the air conditioner is switched off,
switch it back on.
Condensation forms in the air con-
ditioner system during operation,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
