Instruments and controls79Caution
If the needle is in the red warning
zone, the maximum permitted
engine speed is exceeded. Engine at risk.
Fuel gauge
Displays the fuel level in the tank.
Control indicator o illuminates if the
level in the tank is low.
Never run the fuel tank dry.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified fuel tank capacity.
Engine coolant temperature
gauge
Displays the coolant temperature.
50:engine operating temperature
not yet reached90:normal operating temperature130:temperature too high
Control indicator o illuminates if
engine coolant temperature is too
high.
Caution
If engine coolant temperature is
too high, stop vehicle, switch off
engine. Danger to engine. Check
coolant level.
Engine oil level monitor
The state of the engine oil level is
displayed in the Driver Information
Centre for a few seconds following
the service information after switching
on the ignition.
A proper state of engine oil level is
indicated by the message Oil level
correct .
If engine oil level is low, I flashes
and Oil level incorrect is indicated,
accompanied by the C indicator.
Confirm engine oil level by using the
dipstick and top up engine oil
respectively.

A fault of measurement is indicated
by the message Oil level
measurement invalid . Check engine
oil level manually by using the
dipstick.

132Driving and operatingDo not dilute AdBlue.
Otherwise the selective catalytic
reduction system could be
damaged.
Note
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.
Whenever a filling pump with a

available at a filling station, use only
AdBlue bottles or canisters with a

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.
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
Note
Refill the tank to a level of at least
5 l to ensure that the new AdBlue
level is being detected.
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 20 km/h.
2. If AdBlue refill is detected successfully, AdBlue supply-
driven warnings or limitations will disappear.
If AdBlue refill is still not detected,
seek the assistance of a workshop.
If AdBlue must be refilled at
temperatures below -11 °C, the
refilling of AdBlue may not be
detected by the system. In thisevent, park the vehicle in a space
with a higher ambient temperature
until AdBlue is liquified.
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.
It is recommended to fill the AdBlue
tank completely.
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 left rear side of the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked.
1. Switch off ignition.
2. Close all doors to avoid ammonia fumes entering the interior of the
vehicle.
3. Release the fuel filler flap by pushing the flap 3 167.

168Driving and operating9Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
A label with symbols at the fuel filler
flap is indicating the allowed fuel
types. In Europe the pump nozzles of the filling stations are marked with
these symbols. Refuel only the
allowed fuel type.
Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at left rear
side of vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked. Release the
fuel filler flap by pushing the flap.
Petrol and diesel refuelling To open, turn the cap slowly
anticlockwise.The fuel filler cap can be attached to
the hook on the fuel filler flap.
Place the nozzle in straight position to the filler neck and press with slight
force to insert.
To refuel, switch on pump nozzle.
After the automatic cut-off, the tank can be topped up by operating the
pump nozzle a maximum of two more
times.
Caution
Wipe off any overflowing fuel
immediately.

Driving and operating169To close, turn the fuel filler cap
clockwise.
Close the flap and allow it to engage.
Fuel filler cap Only use genuine fuel filler caps.Diesel-engined vehicles have special
fuel filler caps.Trailer hitch
General information
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment. Only use
approved towing equipment.
The bulb outage detection function for trailer or bike carrier brake light
cannot detect a partial bulb outage.
E.g. in case of four bulbs with a power
of 5 W each, the function only detects
lamp outage when only a single 5 W lamp remains or none remain.
LED lights are not suitable for the
wiring harness of this trailer hitch.
Towing equipment could cover the
opening of the towing eye. If this is the case use the coupling ball bar for
towing.Driving characteristics and
towing tips
Before attaching a trailer, lubricate the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements.
During trailer towing do not exceed a
speed of 80 km/h. A maximum speed
of 100 km/h is only appropriate if an
oscillation damper is used and the
permissible gross trailer weight does
not exceed the vehicle’s curb weight.
For trailers with low driving stability
and caravan trailers, the use of an
oscillation damper is strongly
recommended.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 230.
