tion, a message will appear on the Control

Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between

If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control
Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur. <

eling, otherwise, fuel cannot be added to
the tank and a messag e will be displayed.<
Take all precautionary measures and
observe all applicable regulations when
handling fuel. Do not carry any spare fuel con-
tainers in your vehicle. They can develop a leak

instructions provided at filling stations,
otherwise there is a risk of personal injury or
property damage. <
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid lifting the filler
nozzle while filling the tank, as that would
lead to
> premature pump shutoff
> reduced efficiency of the fuel-vapor recov-
ery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
