Eco guide & Power guide*
Instantaneous value
The instantaneous value is shown here - the
higher the reading on the scale, the better.
Eco guide and Power guide are two com-
bined instrument panel (p. 68) instruments
which help the driver to drive the car with
optimum driving economy.
The instantaneous value is calculated based
on speed, engine speed, engine power uti-
lised plus use of the foot brake.
The car also stores statistics of journeys
made, which can be viewed in the form of a
block diagram; see Trip computer - trip statis-
tics* (p. 129).
Optimum speed (50-80 km/h (30-50 mph))
and low engine speeds are encouraged. The
pointers fall during acceleration and braking.

Eco guide
This instrument provides an indication of how
economically the car is being driven.
Very low instantaneous values illuminate the
red zone on the meter (with a short delay),
which means poor driving economy and
hence should be avoided.

Average value
Available engine power
The average value slowly follows the instanta-
neous value and describes how the car has
been driven most recently. The higher the
pointers on the scale, the better the economy
achieved by the driver.
The smaller, upper pointer shows the availa-
ble engine power9. The higher the reading on
the scale, the more power is available in the
current gear.
Engine power utilised
Power guide
The larger, lower pointer shows the engine
power utilised9. The higher the reading on the
scale, the more power is being taken from the
engine.
This instrument shows the relationship
between how much power (Power) is being
taken from the engine and how much power
is available.
A large gap between the two pointers indi-
cates a large power reserve.
