Brake Assist; Hill Start Assist - Opel ASTRA Owner's Manual

174 Driving and operating
Do not operate electrical parking
brake system too often without
engine running because this will
discharge the battery.
Before leaving the vehicle, check the
electrical parking brake status.
Control indicator m 3 116.
Releasing
Switch on ignition. Keep brake pedal
depressed and then push switch m.
Drive away function
Depressing clutch pedal (manual
transmission) or engaging drive gear
(automatic transmission) and then
depressing the accelerator pedal
releases the electrical parking brake
automatically. This is not possible
when the switch is pulled at the same
time.
This function also helps driving away
on inclines.
Aggressive drive away may reduce
life time of wear parts.
Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, the electrical
parking brake system will decelerate
the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Fault
Failure mode of electrical parking
brake is indicated by control indicator
j and by a code number or a vehicle
message which is displayed in the
Driver Information Centre. Vehicle
messages 3 127.
Apply electrical parking brake: pull
and hold the switch m for more than
5 seconds. If control indicator m
illuminates, electrical parking brake is
applied.
Release electrical parking brake:
push and hold the switch m for more
than 2 seconds. If control indicator
m extinguishes, electrical parking
brake is released.
Control indicator m flashes: electrical
parking brake is not fully applied or
released. When continuously
flashing, release electrical parking
brake and retry applying.

Brake assist

If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.

Hill start assist

The system helps prevent unintended
movement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as
soon as the vehicle begins to
accelerate.
