Tachometer Engine oil temperature Fuel gauge The orange pre-warning zone appears
depending on the engine temperature.
As the engine temperature increases,
more and more of the sectors of this
pre-warning zone disappear.
Avoid engine speeds in the pre-warning
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-man-
agement system interrupts the fuel
supply when you approach this sector.39mus023
The normal operating temperature
range is between + 176 7 (+ 80 6) and
+ 248 7 (+ 120 6). Do not exceed the
maximum temperature of +302 7
(+150 6). 39mus024
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. 2.5 gal
(10 liters) of fuel still in the tank.
For fuel tank capacity, refer to
page 143.
If the tilt of the vehicle varies (when you
are 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.<39mus025
