NOTE:
- When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
- Tighten the fuel filler cap about a quarter turn

CAUTION!
For diesel engines, only use diesel fuel for
motor vehicles in accordance with EN 590
European specifications. The use of other
products or mixtures may damage the engine
beyond repair and consequently void the
warranty, due to the damage caused. If you
accidentally introduce other types of fuel into
the tank, do not start the engine. Empty the
tank. If the engine has been run for even an
extremely limited amount of time, you must
not only drain the fuel tank, but the rest of the
supply circuit as well.
After fuel has been added, the vehicle
diagnostic system can determine if the fuel filler
cap is possibly loose, improperly installed, or
damaged. If the system detects a malfunction,
the “gASCAP” message will display in the
odometer display...
Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel
system. Proper maintenance of the engine fuel
filter and fuel tank is essential...
