Driving and operating169Caution
Fuel grades other than those listedon pages 3 216, 3 284 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 x) from the exhaust and turns it
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.
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
The AdBlue tank level can be found in the display menu.

170Driving and operatingLevel warnings
Depending on the calculated range of
AdBlue, different messages are
displayed in the Driver Information
Centre. The messages and the
restrictions are a legal requirement.
The first possible warning is AdBlue
Range: 2400 km .
This warning will show up once briefly with the calculated range. Driving is
possible without any restrictions.
The next warning level is entered with
a range below 1750 km. The
message with the current range will
always be displayed when ignition is
switched on and needs to be
confirmed 3 114 . Refill AdBlue before
entering the next warning level.
At an AdBlue range below 900 km,
the following warning messages are
alternately displayed and cannot be
dismissed:
● AdBlue Low Refill Now
● Engine Restart Prevented in 900
km
Additionally, control indicator Y
flashes continuously.Note
In case of high AdBlue consumption,
the Driver Information Centre may
display this warning without the
previous warning stages.
The last warning level is entered
when the AdBlue tank is empty.
Restart of the engine is not possible.
The following warning messages are
alternately displayed and cannot be
dismissed:
● AdBlue Empty Refill Now
● Engine Will Not Restart
Additionally, control indicator Y
flashes continuously.
With active prevention of an engine
start, the following message will be
displayed:
Refill AdBlue To Start Vehicle .
The tank must be refilled completely
with AdBlue, otherwise restarting of the engine is not possible 3 289.High emission warnings
If the exhaust emission rises above a
certain value, warnings similar to the
range warnings will be displayed in
the Driver Information Centre.
Requests to have the exhaust system checked and finally the
announcement of the prevention of
an engine restart are displayed.
These restrictions are a legal
requirement.
Consult a workshop for assistance.
Refilling AdBlueCaution
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.

Driving and operating171Note
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 Opel dealers and other retail
outlets.
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
Note
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.
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, which is located at right rear side of the
vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked.
1. Remove key from ignition switch.
2. Close all doors to avoid ammonia fumes entering the interior of the
vehicle.
3. Release the fuel filler flap by pushing the flap 3 219.
4. Unscrew protective cap from the
filler neck.
5. Open AdBlue canister.
6. Mount one end of the hose on the
canister and screw the other end
on the filler neck.
7. Lift the canister until it is empty, or
until the flow from the canister has stopped. This can take up to
5 minutes.
8. Place the canister on the ground to empty the hose, wait
15 seconds.
9. Unscrew the hose from the filler neck.
10. Mount the protective cap and turn
clockwise until it engages.
Note
Dispose of AdBlue canister
according to environmental
requirements. To reuse the hose
flush it with clear water after usage.

Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.

If brake pedal is depressed quickly
and forcefully, maximum brake force
is automatically applied.
Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance
when depressing the brake pedal.
Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake
pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain on for further two seconds. The
brakes release automatically as soon
as the vehicle begins to accelerate.Ride control systems
Traction Control system The Traction Control system (TC) is a component of the Electronic Stability
Control (ESC).
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational after each engine
start as soon as the control indicator
b extinguishes.
When TC operates b flashes.
