0 Wipers retractedThe wipers are partially hidden behind
the hood. To bring the wipers up into
their vertical position (important when
changing the blades, or folding up
when frost is expected):
Switch on the wipers and switch off the
ignition when the wipers are approxi-
mately vertical.
Fold the wipers down onto the
windshield before turning on the
ignition key. Failure to do this could
result in damage to the wiper/washer
system and hood.< 1 Intermittent operationThe length of the interval is varied auto-
matically according to the vehicle's
actual road speed.2 Normal wipeThe wipers automatically revert to inter-
mittent operation when the vehicle is
stationary.
3 Fast wipeWhen the vehicle is stationary, the
system does not switch to a lower
wiper speed.4 Brief wipeThe wipers move once across the wind-
shield.5 Cleaning the windshieldThe system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
If you only pull the lever briefly, the
system sprays washer fluid onto the
windshield without activating the
wipers.

Cruise control
*
You can maintain and store any desired
vehicle speed above approx. 25 mph
(40 km/h).
The system is switched off and the
stored speed deleted from its memory
when you turn the ignition key to posi-
tion 0.
Do not use the cruise control on
winding roads, when high traffic
density prevents driving at a constant
speed, when the road surface is slick
(snow, rain, ice) or when the road
surface is loose (rocks or gravel,
sand).< 365us059
To maintain and store speed/
to acceleratePress the lever briefly in direction 1:
The system maintains and stores the
current vehicle speed. Every time you
briefly press the lever, the speed
increases by approx. 0.6 mph (1 km/h).
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 and stores the current speed.
If, on a downhill grade, the engine
braking effect is not sufficient, the
controlled speed can be exceeded.
Speed can drop on uphill grades if the
engine output is insufficient.< To deceleratePress the lever briefly in direction 2:
If you are already driving with active
cruise control, the speed is decreased
by approx. 0.6 mph (1 km/h) every time
you briefly touch the lever.
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
maintains and stores the current speed.Call up stored setting (resume)Press the lever briefly in direction 3:
The vehicle accelerates to and main-
tains the last speed stored.To deactivatePress the lever briefly in direction 4:
The cruise control is deactivated imme-
diately.
In addition, the system is also automati-
cally deactivated in response to the
following conditions:
>When you apply the brakes
>When you depress the clutch or move
the automatic transmission selector
lever from "D" to "N"
>If you exceed or fall below the preset
speed for an extended period (by
depressing the accelerator, for
example).

Never allow the engine to operate with
the needle in the red overspeed sector
of the gauge.
To protect the engine, the engine-
management system automatically
interrupts the fuel supply in this range;
you will notice a loss of power.367de005
When you switch on the ignition, the
indicator lamp comes on briefly to
confirm that the system is operational.
Once the indicator lamp stays on
continuously, there are still approx.
2.1 gallons (8 liters) of fuel in the fuel
tank.
Tank capacity: page 173.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.< 367us006

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.

Outside temperatureIf the outside temperature drops to
approx. +37.5 7 (+3 6), a warning
signal sounds (ice warning). The
temperature display appears automati-
cally and flashes for 8 seconds.
The warning is repeated whenever the
temperature has reached at least
+43 7 (+6 6) and then drops to
+37.5 7 (+3 6) again.
The ice warning does not alter the
fact that surface ice can form at
temperatures above +37.5 7 (+3 6),
on bridges or shaded road surfaces, for
instance.< 367us712

Average fuel consumptionThe calculation is made when the
engine is running. Periods when the
vehicle is parked and the engine is not
running are not included.
New calculation:
When this function has been activated
and you press the button, the fuel
consumption is recalculated from that
point in time.367us713
Estimated cruising rangeThe computer bases its calculations of
the cruising range on the previous
driving style and on the remaining fuel.
When three dashes flash in the display,
the cruising range is below 9 miles
(15 km). You should refuel as soon as
possible.
Refueling is registered by the computer
with the ignition key in position 1 or
higher.
If the vehicle has been parked at
an angle, the cruising range
cannot be displayed accurately. The
display will be corrected while the
vehicle is moving.< 367us714
Average speedPeriods when the vehicle is parked and
the engine is switched off are not
included in the calculation.
At speeds below 100 mph or 100 km/h,
the display includes decimals.
New calculation:
When this function has been activated
and you press the button, the
average speed is recalculated from that
point in time. 367us715
