2016.25 VAUXHALL ASTRA J brake sensor

Storage73● Do not allow the load to protrudeabove the upper edge of the
backrests.
● Do not place any objects on the load compartment cover or the
instrument panel, and do not
cover the sensor on top of the instrument panel.
● The load must not obstruct the operation of the pedals, parking
brake and gear selector lever, or
hinder the freedom of movement
of the driver. Do not place any
unsecured objects in the interior.
● Do not drive with an open load compartment.9Warning
Always make sure that the load in
the vehicle is securely stowed.
Otherwise objects can be thrown
around inside the vehicle and
cause personal injury or damage
to the load or car.
● The payload is the difference between the permitted gross
vehicle weight (see identification
plate 3 242) and the EC kerb
weight.
To calculate the payload, enter
the data for your vehicle in the
weights table at the front of this
manual.
The EC kerb weight includes
weights for the driver (68 kg),
luggage (7 kg) and all fluids (fuel
tank 90% full).
Optional equipment and
accessories increase the kerb
weight.
● Driving with a roof load increases
the sensitivity of the vehicle to
cross-winds and has a
detrimental effect on vehicle
handling due to the vehicle's
higher centre of gravity.
Distribute the load evenly and secure it properly with retaining
straps. Adjust the tyre pressure
and vehicle speed according to
the load conditions. Check and
retighten the straps frequently.
Do not drive faster than 75 mph.
The permissible roof load is
75 kg. The roof load is thecombined weight of the roof rack and the load.

168Driving and operatingGeneral information9Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
System limitations
The system is designed to warn on vehicles only, but may react also to
other objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● on winding roads
● when weather limits visibility, such as fog, rain, or snow
● when the sensor is blocked by snow, ice, slush, mud, dirt,
windscreen damage or affected
by foreign items, e.g. stickers
Following distance indication
The following distance indication
displays the distance to a preceding
moving vehicle. The front camera in
the windscreen is used to detect the
distance of a vehicle directly ahead in
the vehicle's path. It is active at
speeds above 25 mph.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre.On Midlevel display, choose Info
Menu ? via MENU on the turn
signal lever and turn the adjuster wheel to choose following distance
indication page, 3 97
On Uplevel display, select Info menu
via steering wheel buttons and press o to select following distance
indication 3 97.
The minimum indicated distance is 0.5 seconds.
If there is no vehicle ahead or the
vehicle ahead is out of range, two
dashes will be displayed: -.- sec.

Driving and operating169Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles and obstacles
directly ahead, when a collision can no longer be avoided either by
manual braking or by steering. Before the active emergency braking
applies, the driver is warned by the
forward collision alert 3 166.
The feature uses various inputs (e.g.
camera sensor, brake pressure,
vehicle speed) to calculate the
probability of a frontal collision.
Active emergency braking operates
above walking speed up to 53 mph. A precondition is that the system is not
deactivated by toggling the gap
switch V to Off setting, 3 166.
The system includes: ● brake preparation system
● emergency automatic braking
● forward looking brake assist9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only. The driver must continue to apply the brake
pedal as the driving situation
dictates.
Brake preparation system
When approaching a vehicle ahead
so quickly that a collision is likely, the
brake preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or automatic braking is requested.
The brake system is prepared so that braking can occur more rapidly.
The system operates up to a speed of 50 mph.
Emergency automatic braking
After the brake preparation and just
before the imminent collision, this
function automatically applies limited
braking to reduce the impact speed of the collision or prohibit a crash.
The system operates up to a speed of 37 mph.
Below a speed of 25 mph the system
can apply full braking.
Forward looking brake assist
In addition to the brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. Therefore,
depressing the brake pedal less
strongly results in immediate hard
braking. This function helps the driver
brake quicker and harder before the
imminent collision.
The system operates up to a speed of 53 mph.

170Driving and operating9Warning
Active emergency braking is not
designed to apply hard
autonomous braking or to
automatically avoid a collision. It is designed to reduce the vehicle
speed before a collision. It may not
react for pedestrians or animals.
After a sudden lane change, the
system needs a certain time to
detect the next preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver shall always be ready to take action and apply the
brakes and steer to avoid
collisions. The system is designed to work with all occupants wearingtheir seat belts.
System limitations
The active emergency braking has
limited or no function during rain,
snow or heavy dirt, as the camera
sensor can be covered by a water
film, dust, ice or snow. In case of
sensor blockage, clean the sensor
cover.
In some cases, the active emergency braking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
service. Firmly apply the accelerator
pedal to override the automatic
braking.
Deactivation
Active emergency braking can be
deactivated by repeatedly pressing
the gap switch V to Off setting,
3 166. If deactivated a message is
displayed in the Driver Information
Centre.
Fault
In the event of a system service
requirement, a message is displayed
in the Driver Information Centre.
If the system does not work as it
should do, vehicle messages are
displayed in the Driver Information
Centre.
Vehicle messages 3 104.
Parking assist Rear parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.

Information Centre 3 97. This setting
is the reference for the tyre pressure
warnings.
The Tyre load menu only appears if
the vehicle is in a standstill and the
parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.

Vehicle Information Menu ? in the
Driver Information Centre 3 97.
Select
● Light for comfort pressure up to
three people.
● Eco for Eco pressure up to three
people.
● Max for full loading.

Tyre pressure sensor matching
process
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating the wheels or exchanging the
complete wheel set and if one or more tyre pressure sensors were replaced.
The tyre pressure sensor matching
process should also be performed
after replacing a spare wheel with a
road wheel containing the tyre
pressure sensor.
The malfunction light w and the
warning message or code should go
off at the next ignition cycle. The
sensors are matched to the wheel
positions, using a relearn tool, in the following order: left side front wheel,
right side front wheel, right side rear
