Automatic deactivation: ● Vehicle speed is below approx. 25 km/h.
● The brake pedal is depressed.
● The clutch pedal is depressed for
a few seconds.
● The selector lever is in N.
● Engine speed is in a very low range.
● The Traction Control system or Electronic Stability Control is
operating.Resume stored speed
Turn thumb wheel to RES/+ at a
speed above 25 km/h. The stored
speed will be obtained.
Switching off the system
Press m, control indicator m in
instrument cluster extinguishes. The
stored speed is deleted.
Pressing L to activate the speed
limiter or switching off the ignition also switches off cruise control and
deletes the stored speed.
Speed limiter
The speed limiter prevents exceeding a preset maximum speed.
The maximum speed can be set at
speeds above 30 km/h.
The driver can only accelerate up to
the preset speed. Deviations from the
limited speed may occur when driving
downhill.
The preset speed limit is displayed in
the Driver Information Centre when
the system is active.

Driving and operating129When the system recognises an
unintended lane change, control
indicator ) changes to yellow and
flashes. Simultaneously a chime
sound is activated.
Deactivation
The system is deactivated by
pressing ), the LED in the button
extinguishes.
At speeds below 56 km/h the system
is inoperable.
Fault
The lane departure warning system may not operate properly when:
● The windscreen is not clean.
● There are adverse environmental
conditions e.g. heavy rain, snow,
direct sunlight or shadows.
The system can not operate when no lane marking is detected.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.

130Driving and operatingCaution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to EN 228 or equivalent can lead todeposits or engine damage.
Caution
Use of fuel with a lower octane
rating than the lowest possible
rating could lead to uncontrolled combustion and engine damage.
The engine specific requirements
regarding octane rating are given in
the engine data overview 3 182. A
country specific label at the fuel filler
flap can supersede the requirement.
Fuel additive
Fuel should contain detergent
additives that help prevent engine
and fuel system deposits from
forming. Clean fuel injectors and
intake valves will allow the emission
control system to work properly. In
certain countries fuel does not
contain sufficient quantities of
additive to keep fuel injectors and
intake valves clean. In these
countries a fuel additive is required for
some engines to make up for this lack
of detergency. Only use fuel additive
approved for the vehicle.
Adding fuel additive to the filled fuel
tank is required at least every 15,000 km or after one year, whichever
occurs first. For further information,
contact your workshop.
Prohibited fuels
Fuels containing oxygenates such as
ethers and ethanol, as well as
reformulated fuel, are available in
some cities. If these fuels comply with the previously described
specification, then they are
acceptable to use. However, E85(85% ethanol) and other fuels
containing more than 15% ethanol
must be used only in FlexFuel
vehicles.Caution
Do not use fuel containing
methanol. It can corrode metal
parts in the fuel system and also
damage plastic and rubber parts.
This damage would not be
covered by the vehicle warranty.
Some fuels, mainly high octane
racing fuels, can contain an octane
enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use fuels or fuel additives with MMT as they can
reduce spark plug life and affect
emission control system
performance. The malfunction
indicator light Z may illuminate 3 74.
If this occurs, seek the assistance of
a workshop.

132Driving and operatingCaution
In case of misfuelling, do not
switch on ignition.
1. Stop the engine.
2. Pull up the fuel filler flap release lever located on the floor, left front
side of driver's seat.
The fuel filler flap is located at right
rear side of the vehicle.
3. Turn the fuel filler cap counterclockwise slowly. If a
hissing sound is heard, wait for it
to stop before completely
unscrewing the cap.
4. Remove the cap. The cap is tethered to the vehicle.
5. 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.
6. To close, turn the fuel filler cap clockwise until it clicks.
7. Push the fuel filler flap closed until
it latches.
Note
If, in cold weather, the fuel filler door
does not open, tap the door lightly.
Then try to open it again.
Liquid gas refuelling
Follow the operating and safety
instructions of the filling station when
refuelling.
Filling adapter
As filling systems are not
standardised, different adapters are
required which are available from
Opel Distributors and from Opel
Authorised Repairers.

The maximum engine oil
consumption is 0.6 l per 1000 km.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 5 minutes.Pull out the dipstick, wipe it clean,
reinsert it fully, pull out and read the
engine oil level.
When the engine oil level has
dropped to the MIN mark, top up
engine oil.
We recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.

Vehicle care139Caution
Overfilled engine oil must be
drained or suctioned out. If the oil exceeds the maximum level, do
not start the vehicle and contact a
workshop.
Capacities 3 185.
Fit the cap on straight and tighten it.
Engine coolant The coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C.
Caution
Only use approved antifreeze.
Coolant and antifreeze 3 175.
Coolant levelCaution
Too low a coolant level can cause
engine damage.
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.

140Vehicle careWasher fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
