How can I optimise m

?
G

f
erence to Auto mode as it selects in the best wa

the "drivin

order to reduce

tion.
You should also adapt

g
et the best
out of it, for example b

takin

It is not ZEV mode but Auto mode that is the most appropriate
f
or reducin
g
f
uel consumption, as it
s
elects the best "drivin
g
ener
gy
source".
ZEV mode
(
100% electric operation
)
can reduce fuel consumption in some cases. However,
rechar
g
in
g
the traction batter
y
has an ener
gy
cost.
This is wh
y
we recommend usin
g
Auto mode more often.

consumption in

wn?
The current fuel consumption displa
y
ed ma
y
appear hi
g
h when the distance covered is ver
y
low,
but this
g
enerall
y
has ver
y
little impact and the true avera
g
e fuel consumption will remain low.
In town,
y
our h

(
of the order of 35% better than a non-h

)
.

A
partl

char

is normal operation
(
4 to 5 bars on avera

)
.
This allows some capacit
