Driving and operating151Driving hints
Control of the vehicle
Never coast with engine not
running
Many systems will not function in this
situation ( e.g. brake servo unit, power
steering). Driving in this manner is a danger to yourself and others.
All systems function during an
Autostop.
Stop-start system 3 156.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.Use only floor mats, which fit properly and are fixed by the retainers on the
driver side.
Steering If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system. Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and engine oil consumption may be
higher.
Additionally, the cleaning process of
the exhaust filter may take place more
often.
Exhaust filter 3 161.

Driving and operating161Engine exhaust9Danger
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.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Exhaust filter
The exhaust filter is a particle filter for diesel and petrol engines.
Automatic cleaning process
The exhaust filter system filters soot
particles out of the exhaust gases.
The system includes a self-cleaning
function that runs automatically
during driving without any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions and may take up to
25 minutes. Typically it needs
between 7 and 12 minutes. Autostop
is not available and fuel consumption may be higher during this period. The
emission of smells and smoke during
this process is normal.
System requires cleaning
Under certain conditions, e.g. driving
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and if previous driving conditions did not
enable automatic cleaning, it will be
indicated by a warning message in
the Driver Information Centre.A warning message appears when
exhaust filter is full. Start cleaning
process as soon as possible.
A warning message also appears
when exhaust filter has reached the
maximum filling level. Start cleaning
process immediately to avoid
damage to the engine.
Activate self-cleaning process
Cleaning process is completed more
quickly at high engine speeds and
loads. Therefore, drive in lower gears
than normal, and use manual gear
selection on vehicles with automatic
transmission. Usage of electrical
consumers like air conditioning and
heated windows to increase engine
load supports cleaning process.Caution
If possible, do not interrupt
cleaning process. Drive until
cleaning is completed to avoid the
need for service or repair by a
workshop.

4. Unscrew protective cap from thefiller 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.
Notice
Dispose of AdBlue canister
according to environmental
requirements. To reuse the hose
flush it with clear water after usage.Automatic transmission
The automatic transmission permits
automatic gearshifting (automatic
mode) or manual gearshifting
(manual mode).
Manual shifting is possible in manual
mode by tapping the selector lever to + or - 3 167.
Continuous variable transmission The engine speed is always within the
ideal fuel consumption range. When
selector level is in D and high power
is requiered, the electronic
transmission control changes from
stepless operation to a seven step
automatic shifting.

Driving and operating211Manual switch off the lane keep assist
if the system is disturbed by tar
marks, shadows, road cracks,
temporary or construction lane
markings, or other road
imperfections.9 Warning
Always keep your attention on the
road and maintain proper vehicle
position within the lane, otherwise
vehicle damage, injury or death
could occur.
Lane keep assist does not
continuously steer the vehicle.
The system may not keep the
vehicle in the lane or give an alert,
even if a lane marking is detected.
The steering of the lane keep
assist may not be sufficient to
avoid a lane departure.
The system may not detect hands-
off driving due to external
influences like road condition and
surface and weather. The driver has full responsibility to control the
vehicle and is always required to
keep the hands on the steering
wheel while driving.
Using the system while towing a
trailer or on slippery roads could
cause loss of control of the vehicle
and a crash. Switch the system off.Fuel
Fuel for petrol engines
Only use unleaded fuel that complies
with European standard EN 228 or
equivalent.
The engine is capable of running with
fuel that contains up to 10% ethanol
(e.g. named E10).
Use fuel with the recommended
octane rating. A lower octane rating can reduce engine power and torque
and slightly increases fuel
consumption.

Accessories and vehiclemodifications
We recommend the use of genuine
parts and accessories and factory approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products - even if they have a regulatory or
otherwise granted approval.
Any modification, conversion or other
changes made to standard vehicle
specifications (including, without
limitation, software modifications,
modifications of the electronic control units) may invalidate the warranty
offered by Vauxhall. Furthermore,
such changes may affect driver
assistance systems, fuel
consumption, CO 2 emissions and
other emissions of the vehicle. They
may also invalidate the vehicle
operating permit.

Vehicle care249The tyre pressure information label
on the left door frame indicates the
original equipment tyres and the
correspondent tyre pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter
tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Make sure tyre loading setting
matches the current tyre pressure.
Tyre loading 3 250.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options.
For the correct tyre pressure value,
follow the procedure below:
● Identify the engine identifier code.Engine data 3 278.
● Identify the respective tyre. ● The tyre pressure tables show all
possible tyre combinations
3 283.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
The tyre pressure value displayed in
the Driver Information Centre shows
the real tyre pressure. A cooled down tyre will show a decreased value,
which does not indicate an air leak.
