Forward collision alert The forward collision alert can help to
avoid or reduce the damage caused
by front-end crashes. If a vehicle directly ahead is approached too
quickly, a warning chime and alert in
the Driver Information Centre is
provided.The green illuminated vehicle ahead
symbol A appears in the
speedometer when the system has
detected a vehicle in the driving path. A precondition is that forward collision
alert is activated in the vehicle
personalisation menu 3 99 or that it is
not deactivated with button V
(depending on the system, see
following).
Forward collision alert based on
front camera system Forward collision alert uses the front
camera system in the windscreen to
detect a vehicle directly ahead, in
your path, within a distance of approx.
60 metres.
Activation
Forward collision alert operates
automatically above 40 km/h, if it is not deactivated with button V, see
below.

Driving and operating141Parking assist
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles,
and giving acoustic signals. It is the
driver, however, who bears full
responsibility for the parking
manoeuvre.
The system consists of four ultrasonic parking sensors in the rear bumper. If
the vehicle is equipped with a front
parking assist the system consists of
four additional ultrasonic parking
sensors in the front bumper.
Control indicator r 3 86.
Activation
When reverse gear is engaged, the
system is activated automatically.
The front parking assist can also be activated at a low speed by pressing
the r button.
An illuminated LED in the parking assist button indicates that the
system is ready to operate.
An obstacle is indicated by a buzzing
sound. The interval between the sounds becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm, the buzzing is continuous.
If the r button is pressed once
within an ignition cycle, the front
parking assist is always reactivated
when the vehicle speed goes below a certain value.
Deactivation
Deactivate the system by pressing
the r button.
The LED in the button will go out and
Park Assist Off will be displayed in the
Driver Information Centre.
The system is deactivated
automatically at a certain speed.
Fault
In the event of a fault in the system,
r illuminates or a vehicle message
is displayed in the Driver Information
Centre.

Fault
The traffic sign assistant system may
not operate correctly when:
■ the area of the windscreen, where the front camera is located, is notclean
■ traffic signs are completely or partially covered or difficult to
discern
■ there are adverse environmental conditions, e.g. heavy rain, snow,direct sunlight or shadows. In this
case No Traffic Sign Detection due
to Weather is indicated on the
display
■ traffic signs are incorrectly mounted
or damaged
■ traffic signs do not comply with the Vienna Convention on traffic signs
(Wiener Übereinkommen über
Straßenverkehrszeichen)Caution
The system is intended to help the driver within a defined speed
range to recognise certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not recognise
any other than the conventional
traffic signs that might give or end
a speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.

Replacing the vehicle battery Note
Any deviation from the instructions
given in this section may lead to
temporary deactivation 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.Only use vehicle batteries that allow
the fuse box to be mounted above the
vehicle battery.
In vehicles with stop-start system, be
sure to have the AGM (Absorptive
Glass Mat) battery replaced with
another AGM battery.
An AGM battery can be identified by
the label on the battery. We
recommend the use of an original
Opel vehicle battery.
Note
Using an AGM vehicle battery
different from the original Opel
vehicle battery may result in a lower performance of the stop-start
system.
We recommend that you have the
vehicle battery replaced by a
workshop.

Charging the vehicle battery9 Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed
14.6 volts when using a battery
charger. Otherwise the vehicle
battery might be damaged.
