The correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded
petrol. The petrol must comply with the
standard EN 228 and be sulphur-free. Fuels
with a 10% ethanol ratio can be refuelled

Practical tips
Super unleaded petrol 95 octane petrol or
normal 91 octane petrol at least
We recommend refuelling with super 95 oc-
tane petrol (91 AKI). If not available: normal 91
octane petrol (87 AKI) (with a slight power
loss).
Super unleaded petrol, 95 octanes at
least
You should use super 95 octane petrol (91
AKI) at least.
If super is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
use moderate engine speeds and a light
throttle. Refuel with super as soon as possi-
ble.
Unleaded super plus 98 octane petrol or
super 95 octane petrol at least
We recommend refuelling with super plus 98
octane petrol (93 AKI). If not available: super
95 octane petrol (91 AKI) (with a slight power
loss).
If super is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
use moderate engine speeds and a light
