2018.5 VAUXHALL ASTRA J GTC torque

Driving and operating141Automatic Starter ControlThis function controls the engine
starting procedure. The driver does
not need to hold the key in position 3.
Once applied, the system will go on starting automatically until the engine is running. Because of the checkingprocedure, the engine starts running
after a short delay.
Possible reasons for a non-starting
engine:
● Clutch pedal not operated (manual transmission).
● Brake pedal not operated or selector lever not in P or N
(automatic transmission).
● Timeout occurred.
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It starts the engine
automatically as soon as the clutch is
depressed. A battery sensor ensures
that an Autostop is only performed if
the vehicle battery is sufficiently
charged for a restart.
Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.Deactivation
Deactivate the stop-start system
manually by pressing eco. The
deactivation is indicated when the
LED in the button extinguishes.
Autostop If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● Depress the clutch pedal.
● Move the selector lever to neutral.
● Release the clutch pedal.

Driving and operating187The 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.
Caution
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 to
deposits 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 3 261. A
country specific label at the fuel filler
flap can supersede the requirement.

240Vehicle care
Set the jack to the necessary
height. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Attach jack handle and with the
jack correctly aligned rotate
handle until wheel is clear of the ground.
5. Unscrew the wheel nuts.
6. Change the wheel. Spare wheel 3 241.
7. Screw on the wheel nuts.
8. Lower the vehicle and remove jack.
9. Install the wheel wrench ensuring that it is located securely and
tighten each nut in a crosswise
sequence. Tightening torque is
140 Nm.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
Install centre cap on alloy wheels.
11. Install vehicle jacking point cover on versions with sill panelling.
12. Stow the replaced wheel 3 241,
the vehicle tools 3 226 and the
adapter for the locking wheel nuts 3 59.
13. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.Have the defective tyre renewed or repaired as soon as possible.
Jacking position for lifting platform
Rear arm position of the lifting
platform centrically under the recess
of the sill.
