Engine exhaust  
9 Danger  
Lock the vehicle.  
Activate the anti-theft alarm  
system.  
The engine cooling fans may run  
after the engine has been  
switched off 3 186.  
Engine exhaust gases contain  
poisonous carbon monoxide,  
which is colourless and odourless  
and could be fatal if inhaled.  
If exhaust gases enter the interior  
of the vehicle, open the windows.  
Have the cause of the fault  
rectified by a workshop.  
Caution  
Avoid driving with an open load  
compartment, otherwise exhaust  
gases could enter the vehicle.  
After running at high engine  
speeds or with high engine loads,  
operate the engine briefly at a low  
load or run in neutral for  
approx. 30 seconds before  
switching off, in order to protect  
the turbocharger.  
Exhaust filter  
Automatic cleaning process  
The exhaust filter system filters soot  
particles out of the exhaust gases.  
The start of saturation of the exhaust  
filter is indicated by the temporary  
illumination of t or C,  
accompanied by a message in the  
Driver Information Centre.  
Notice  
In the event of an accident with  
airbag deployment, the engine is  
switched off automatically if the  
vehicle comes to a standstill within a  
certain time.

Driving and operating  
As soon as the traffic conditions  
permit, regenerate the filter by driving  
at a vehicle speed of at least 40 mph  
until the control indicator  
Catalytic converter  
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  
(NOx) from the exhaust and turns it

Notice  
Caution  
On a new vehicle, the first exhaust  
filter regeneration operations may  
be accompanied by a burning smell,  
which is normal. Following  
Fuel grades other than those listed  
on pages 3 179, 3 232 could  
damage the catalytic converter or  
electronic components.  
Unburnt petrol will overheat and  
damage the catalytic converter.  
Therefore avoid excessive use of

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.  
Cleaning process not possible  
If t or C stays on, accompanied  
by an audible signal and a message,  
this indicates that the exhaust filter  
additive level is too low.  
The reservoir must be topped-up  
without delay. Seek the assistance of  
a workshop.  
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.  
9 Warning  
Avoid contact of your eyes or skin  
with AdBlue.  
In case of eye or skin contact,  
rinse off with water.

A message appears in the Driver  
Information Centre. Additionally,  
control indicator u will flash and  
a chime will sound.  
Refill the tank to a level of at least  
5 l of AdBlue, otherwise restarting  
of the engine is not possible.  
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.  
2. The next warning level is entered  
when the estimated AdBlue range  
is below 500 miles. The message  
with the current range will always  
be displayed when ignition is

will sound. Refill AdBlue before  
entering the next warning level.  
In the event of a fault with the  
emissions control system, different  
messages are displayed in the Driver  
Information Centre.  
The messages and the restrictions  
are a legal requirement. The warning  
messages are accompanied by the  
control indicators u, C and W.  
Additionally, a chime will sound.  
The typical AdBlue consumption is  
approx. 0.85 l per 600 miles, but can  
also be higher depending on driving  
behaviour (e.g. high load or towing).

Driving and operating  
Since AdBlue has a limited  
durability, check the date of expiry  
before refilling.  
Notice  
Refilling AdBlue  
Caution  
When unscrewing the protective cap  
from the filler neck, ammonia fumes  
may emerge. Do not inhale as the  
fumes have a pungent smell. The  
fumes are not harmful by inhalation.  
Notice  
Only use AdBlue that complies  
with European standards  
DIN 70 070 and ISO 22241-1.  
Do not use additives.  
Do not dilute AdBlue.  
Otherwise the selective catalytic  
reduction system could be  
damaged.  
Refill the tank to a level of at least  
5 l to ensure that the new AdBlue  
level is being detected.  
The AdBlue tank should be filled  
completely. This must be done if the  
warning message regarding  
prevention of an engine restart is  
already displayed.  
The vehicle must be parked on a level  
surface.  
The filler neck for AdBlue is located  
behind the fuel filler flap.  
The fuel filler flap can only be opened  
if the vehicle is unlocked.  
In case AdBlue refill is not  
successfully detected:  
1. Continuously drive the vehicle  
for 10 min making sure that  
vehicle speed is always higher  
than 12 mph.  
2. If AdBlue refill is detected  
successfully, AdBlue supply-  
driven warnings or limitations will  
disappear.  
Notice  
Whenever a filling pump with a  
nozzle for passenger cars is not  
available at a filling station, use only  
AdBlue bottles or canisters with a  
sealed refill adapter for refilling, to  
prevent splashback and overspill,  
and in order to ensure that the fumes  
from the tank are captured and do  
not emerge. AdBlue in bottles or  
canisters is available in many filling  
stations and can be purchased e.g.  
at Vauxhall dealers and other retail  
outlets.  
If AdBlue refill is still not detected,  
seek the assistance of a workshop.  
1. Switch off the ignition.  
2. Close all doors to avoid ammonia  
fumes entering the interior of the  
vehicle.  
If AdBlue must be refilled at  
temperatures below -11 °C, the  
refilling of AdBlue may not be  
detected by the system. In this  
event, park the vehicle in a space  
with a higher ambient temperature  
until AdBlue is liquified.  
3. Release the fuel filler flap by  
pushing the flap 3 181.
