Catalytic Converter; Adblue - Opel Grandland X Owner's Manual

Catalytic converter

The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed
on pages 3 194, 3 245 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine
performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.

AdBlue

General information
The selective catalytic reduction
(BlueInjection) is a method to
substantially reduce the nitrogen
oxides in the exhaust emission. This
is achieved by injecting a Diesel
Exhaust Fluid (DEF) into the exhaust
system. The ammonia released by
the fluid reacts with nitrous gases
(NO ) from the exhaust and turns it
x
into nitrogen and water.
The designation of this fluid is
AdBlue ® . It is a non-toxic, non-
flammable, colourless and odourless
fluid which consists of 32% urea and
68% water.
9 Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
Driving and operating
Caution
Avoid contact of the paintwork with
AdBlue.
In case of contact, rinse off with
water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue pre-heater,
the emissions reduction at low
temperatures is ensured. The AdBlue
pre-heater works automatically.
The typical AdBlue consumption is
approx. two litres per 1000 km, but
can also be higher depending on
driving behaviour (e.g. high load or
towing).
AdBlue tank
At a remaining volume of approx. five
litres, there is a liquid level switch.
Warning messages are displayed
only below that threshold. Tank
volume 3 247.
