Parking brake To engageThe lock engages automatically when
you lift the lever, and the indicator lamp
in the instrument cluster will light up in
ignition key position 2. See page 21.To releasePull up slightly on the lever, press the
button (arrow) and lower the lever.
The parking brake is primarily designed
to prevent the vehicle from rolling while
parked, and operates against the rear
wheels.460de024
If, in exceptional circumstances, it
should be necessary to engage
the parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling up the lever to apply mod-
erate pressure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear.
The brake lamps do not come on when
the parking brake is engaged.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined sur-
faces, as placing the lever in 1st gear or
reverse may not provide adequate re-
sistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park".<
To avoid corrosion, apply the parking
brake lightly from time to time when
coasting to a standstill (at a traffic sig-
nal, for instance), provided that it is safe
to do so.

Cruise control You can store and automatically main-
tain any desired vehicle speed above
approx. 20 mph (30 km/h). To activate the system In ignition key positions 1 or 2.
Press button 1. The indicator lamp in
the instrument cluster comes on. You
can now use the cruise control.463de058
To store and maintain speed/
to acceleratePress button 3 briefly:
The system records and maintains the
current vehicle speed. The speed will
now be increased by approx. 0.6 mph
(approx. 1 km/h) every time you briefly
press the button.
Press and hold button 3:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
records and maintains the current
speed.
If, on a downhill gradient, the
engine braking effect is not suffi-
cient, the controlled speed may be
exceeded. Speed may drop on uphill
grades if the engine output is insuffi-
cient.<
To deceleratePress button 2 briefly:
When the cruise control is active, vehicle
speed is reduced by approx. 0.6 mph
(approx. 1 km/h) every time you briefly
press the button.
Press and hold button 2:
With the cruise control active, the sys-
tem automatically reduces the throttle
opening to slow the vehicle. When you
release the button, the system records
and maintains the current speed.To cancel the cruise control When the system is activated, press
button 1. The indicator lamp stays on.
You can use the cruise control again as
required.

1 Odometer You can activate the displays shown in
the illustration with the ignition key in
position 0 by pressing the button in the
instrument cluster (arrow).2 Trip odometerTo reset the trip odometer to zero,
press the button (arrow) with the igni-
tion key in position 1 or 2.462us005
Avoid engine speeds in the red warning
zone of the gauge.
To protect the engine, the engine man-
agement system automatically inter-
rupts the fuel supply in this range; the
resulting effect resembles that associ-
ated with a sudden loss of power.462us017
Indicates the current fuel consumption in
mpg (on Canadian models in l/100 km).
This instrument clearly shows whether
your current driving style is conducive to
economy and minimum exhaust emis-
sions.
The needle goes back to zero when the
car is stationary. 462us018

Onboard computerOutside temperature You can change the units of measure
(6/7) for the outside temperature dis-
play by pressing the right-hand reset
button in the instrument cluster when
the temperature display is active.462us023
Ice warning If the outside temperature sinks to
approx. 37.57 (+ 36), a warning sig-
nal sounds and the display flashes
briefly.
The warning is repeated whenever the
temperature goes to at least 437
(+ 66) and then drops again to 37.57
(+ 36).
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.57 (+ 36),
e. g. on bridges or shaded road sur-
faces.<
Average fuel consumption If you continue to hold the button on the
turn signal lever, the average fuel con-
sumption last displayed is recalculated
from that point in time.462us007
