Fuel and AdBlue® (UREA) Fill Location
1 — Diesel Fuel Filler
2 — AdBlue ® Filler
WARNING!
• Never have any smoking materials lit in
or near the vehicle when the fuel door is
open or the tank is being filled.
• Never add fuel when the engine is run-
ning. This is in violation of most countries
regulations and may cause the "Malfunc-
tion Indicator Light" to turn on.

WARNING!
• Do not apply any object/cap to the end of
the filler which is not provided for the
car. The use of non-compliant objects/
plugs could cause a pressure increase
inside the tank, resulting in dangerous
situations.
• A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always
place fuel containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emission
control system could result from using
an improper fuel filler cap. A poorly
fitting cap could let impurities into the
fuel system. Also, a poorly fitting after-
market cap can cause the "Malfunction
Indicator Light (MIL)" to illuminate, due
to fuel vapors escaping from the system.
• To avoid fuel spillage and overfilling, do
not "top off" the fuel tank after filling.
NOTE:
• When the fuel nozzle "clicks" or shuts off,
the fuel tank is full.
• Tighten the fuel filler cap about 1/4 turn
until you hear one click. This is an indica-
tion that the cap is properly tightened.
• If the fuel filler cap is not tightened properly,
the MIL will come on. Be sure the cap is
tightened every time the vehicle is refueled.
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 en-
gine 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.
