Tachometer Engine oil temperature Fuel gauge
The orange early warning zone appears
depending upon the engine tempera-
ture. As the engine temperature in-
creases, more and more sectors of this
early warning zone disappear.
Avoid engine speeds in the early warn-
ing zone if possible.
Do not operate the engine with the
needle in the red overspeed zone of the
gauge.
To protect the engine, the engine-
management system automatically in-
terrupts the fuel supply in this range;
the resulting effect resembles that as-
sociated with a sudden loss of power.

The normal operating temperature is
in a range between +176 7 (+80 6)
and +248 7 (+120 6). Do not exceed
the maximum temperature of +302 7
(+150 6).

When you switch on the ignition, the
indicator lamp comes on briefly to con-
firm that the system is operational.
If the indicator lamp comes on and stays
on, there are approx. 2.6 gal (10 liters)
of fuel still in the tank.
For fuel tank capacity, refer to page 175.
If the tilt of the vehicle varies (when you
are driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, as driving to
the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
