2020 OPEL ASTRA K stop-start

Driving and operating159● The driver's door is closed or thedriver's seat belt is fastened.
● The vehicle battery is sufficiently charged and in good condition.
● The engine is warmed up.
● The engine coolant temperature is not too high.
● The engine exhaust temperature is not too high, e.g. after driving
with high engine load.
● The ambient temperature is above -5 °C.
● The brake vacuum is sufficient.
● Between the last restart and a new Autostop must be about10 seconds.
● The self-cleaning function of the exhaust filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
The stop-start system will be
deactivated on inclines of 12% or
more.Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 141.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 152.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features e.g. auxiliary electric heater
or heated rear window are disabled or switched to a power saving mode.
The fan speed of the climate control
system is reduced to save power.
Restart of the engine by the driverVehicles with manual transmission
Depending on the engine, two
versions of a restart are available.
See engine data to identify the engine
identifier code for your vehicle
3 280.Conventional restart
Depress the clutch pedal to restart the
engine. For engines with late restart,
this is only possible without
depressing the brake pedal.
Late restart ● Depress the brake pedal.
● Depress the clutch pedal.
● Select first gear.
● Release the brake pedal to restart the engine.Vehicles with automatic transmission:Release the brake pedal or move
selector lever out of D into N or P to
restart the engine.
Restart of the engine by the stop-
start system
On vehicles with manual transmission
which are in a conventional Autostop,
the selector lever must be in neutral
to enable an automatic restart.
On vehicles with manual transmission
which are in an early Autostop, an
automatic restart is possible, when
not in neutral if the brake pedal and
the clutch pedal are depressed.

160Driving and operatingOn vehicles with automatic
transmission, the selector lever must
be in D to enable an automatic restart.
The engine will be restarted
automatically by the stop-start
system, if one of the following
conditions occurs during an Autostop:
● The stop-start system is manually deactivated.
● The bonnet is opened.
● The driver's seat belt is unfastened and / or the driver's
door is opened.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
● The brake vacuum is not sufficient.
● The vehicle is driven at least at walking speed.
● The climate control system requests an engine start.● The desired compartmenttemperature does not match theactual temperature.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart might be noticeable.
Note
If a trailer or a bike carrier is
attached, early Autostop and late
restart is deactivated.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake. Activate the manual
parking brake without pressingthe release button. Apply as
firmly as possible on a downhill slope or uphill slope. Depress
brake pedal at the same time to
reduce operating force.
For vehicles with electric
parking brake, pull switch m for
a minimum of 1 second until
control indicator m illuminates
constantly and electric parking
brake is applied 3 110.
● Switch off the engine. ● If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector
lever to position P before
removing the ignition key or
switching off ignition on
vehicles with power button. On
an uphill slope, turn the front
wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P before removing the ignition
key or switching off ignition on

170Driving and operatingWhen clutch slip is detected for a
specific time, the engine power will be
reduced. A warning is displayed in the Driver Information Centre. Release
the clutch.Caution
It is not advisable to drive with the hand resting on the selector lever.
Gear shift indication 3 111.
Stop-start system 3 157.
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.
Control indicator R 3 110.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off, the system performs
a self-test which may be audible.
Control indicator u 3 111.
Adaptive brake light During full braking, all three brake
lights flash for the duration of ABS
control.

228Vehicle careVehicle battery
The vehicle battery is located in the
load compartment.
There are connecting points for jump
starting 3 263.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
Battery discharge protection 3 140.
Disconnecting the battery
If the vehicle's battery is to be
disconnected (e.g. for maintenance
work), the alarm siren must be
deactivated as follows: Switch the ignition on then off, then disconnect
the vehicle's battery within
15 seconds.
Replacing the vehicle battery
Note
Any deviation from the instructions
given in this section may lead to
temporary deactivation or
disturbance of the stop-start system.
When the vehicle battery is being
replaced, please ensure that there
are no open ventilation holes in the
vicinity of the positive terminal. If a
ventilation hole is open in this area, it
must be closed off with a dummy cap, and the ventilation in the vicinity of the
negative terminal must be opened.
Ensure that the battery is always replaced by the same type of battery.
The vehicle battery has to be
replaced by a workshop.
Stop-start system 3 157.
Charging the vehicle battery9 Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed 14.6 V
