Lane Keep Assist - Opel ASTRA Owner's Manual

186 Driving and operating
detection of a new sign although no
sign on the road might have been
passed.
Fault
Traffic sign assistant may not operate
correctly if:
● The area of the windscreen,
where the front camera is
located, is not clean or affected
by foreign items, e.g. stickers.
● 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.
● 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 discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern 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 keep assist

Lane keep assist helps to avoid
crashes due to unintentional lane
departures. The front camera
observes the lane markings. If the
vehicle approaches a lane marking,
the steering wheel is gently turned to
position the vehicle back into the lane.
Override the system by turning the
steering wheel.
Crossing a lane marking significantly
without overriding lane keep assist
starts a visual and acoustic warning.
Unintended lane departure is
assumed
● without using turn signal
● using the turn signal in the
opposite direction of the lane
departure
● without braking
● without acceleration
● without active steering.
Note
The system is switched off during
detection of ambiguous lane
markings, e.g. in construction areas.
Note
The system may be switched off, if it
detects lanes, which are too narrow,
too wide or too much curved.
