66 Instruments and controlsTo calculate the arrival time if a specified
average speed is maintained
1 Select Dist using the button.
2 Set the distance to be covered.
3 Press to select Speed Ø.
4 Set the average speed you intend to
drive.
5 Press SET to display the estimated
arrival time.
At the beginning of a journey, the Speed Ø
and Arriv functions will display current val-
ues. If values are set during the journey, the
new values will be displayed after a delay of
about 10 seconds. Calculating the requisite average speed:
1 Press to select Dist.
2 Set the distance to be covered.
3 Press to select Arriv.
4 Set the desired arrival time.
5 Press SET to display the average speed
you need to maintain to arrive at the
desired time.
At the beginning of a journey, the Speed Ø
and Arriv functions will display current val-
ues. If values are set during the journey, the
new values will be displayed after a delay of
about 10 seconds.Resetting values
To reset the values, press CLEAR for at
least four seconds.
The following functions will be reset
simultaneously:
Estimated range on remaining fuel
(function based on a fuel consumption of
28 mpg).
Average fuel consumption.
Average speed.
Arrival time (function based on current
speed).
Programmed values for Dist, Alarm and
Speed W will not be reset (see the respec-
tive function).

174 Starting and driving
Economical motoringFactors affecting fuel consumption Fuel consumption is greatly affected by the
general driving conditions, the way in which
the car is driven and at what speeds, the
weather, the state of the road, the condition
of the car, etc. Breaking-in Fuel consumption may be somewhat higher
during the break-in period (the first 3,000–
4,000 miles (5,000–7,000 km) than stated.Weather conditions Fuel consumption can be as much as 10 %
lower in summer than in winter. The higher
consumption in cold weather is explained by
the longer time it takes for the engine to
reach normal operating temperature, and
for the transmission and wheel bearings to
warm up. Fuel economy is also affected by
the distance driven: short journeys of 3–
5 miles (5–8 km) do not give the engine
enough time to reach normal temperature.
Strong winds can also affect fuel consump-
tion. How to read the graph above:
If fuel consumption with the engine at
normal temperature is 28 mpg
(10l/100 km), the actual fuel consumption 3
miles (5 km) after the engine has started
from cold will be:
– 23.5 mpg (12l/100 km) at outside temp. of
68°F (20°C) (increase of 20 %).
– 17.7 mpg (16l/100 km) at outside temp. of
32°F (0°C) (increase of 60 %).
– 14 mpg (20l/100 km)) at outside temp. of
–4°F (–20°C) (increase of 100 %).
As can be seen, both the distance travelled
by the car and the outside temperature have
NOTICESuspension modifications, such as
changing the type of wheels, dampers or
springs, can affect the function of the ESP
system.
Always consult a Saab dealer before
changing any suspension components.
