-Short-term memory overview
- Long-term memory overview
The short-term memory collects driving informa­
tion from the time the ignition is sw itched on un­
til it is switched off. If you cont inue driv ing with­
in two hours after switching the ignition off, the
new values are included when calculat ing the cur­
rent trip information.
Unlike the short-term memory , the long-term
memory is not erased automat ically. Yo u can se­
lect the time period for evaluat ing trip informa­
tion you rself .
F or some vehicle functions , you can access the
trip informat ion from the temporary memory in
the line
(D .
Fuel consumption
The current fuel consumption can be displayed
using a bar ~
fig. 8. The average consumpt ion
(mpg) stored in the short-term memory is also
displayed . When the bar turns green, your veh icle
saves fuel by one of the following functions:
-Recuperation : When the vehicle is coasting or
driving downhill, electrical ene rgy can be stor­
ed in the battery. The bar will move toward D.
-Cylinder on demand System*: when the de­
ma nd for power is low and other conditions are
met, the engine automatically de activates fo ur
cylinders. The driver and passengers w ill not
even notice this. The cylinders switch on again
when more power is needed.
(D Tips
Fue l consumptions (average and current),
range and speed are displayed in metric units
on Canadian models.

Vehi­
cle functions
