2018 OPEL COMBO D Owner's Manual

Driving and operating127Brakes
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 your 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 85.
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.
Fault
In the event of a fault, control indicator
u illuminates in the instrument
cluster. Depending on version, a
corresponding warning message,
e.g. ABS unavailable , may also be
displayed in the Driver Information
Centre 3 91.9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Control indicator u 3 85.

128Driving and operatingParking brake
Manual parking brake9 Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
brake pedal at the same time.
A warning chime will sound if a certain
speed is exceeded with the parking
brake applied.
Note
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 91.
Control indicator R 3 85.
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 brake pedal 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 or the two seconds holding
time is over.
If control indicator Z 3 86 illuminates
while driving, there is a fault in the Hill
start assist. Depending on version, a
corresponding warning message,
e.g. Hill holder unavailable , may also

Driving and operating129be displayed in the Driver Information
Centre 3 91. Seek the assistance of
a workshop to have the fault
remedied.
The Hill start assist is not active
during an Autostop.
Stop-start system 3 117.Ride control systems
Traction Control system The Anti-Slip Regulator (ASR) is a
component of the Electronic Stability
Control (ESC).
ASR improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
ASR is operational after each engine
start as soon as the control indicator
R extinguishes.
When ASR operates, R flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.

130Driving and operatingDeactivation
ASR can be switched off when
spinning of drive wheels is required:
press ASR OFF briefly.
LED in button illuminates and,
depending on version, a
corresponding message, e.g. ASR
disconnect , may also be displayed in
the Driver Information Centre 3 91.
ASR is reactivated by pressing
ASR OFF again.
ASR is also reactivated the next time
the ignition is switched on.
Fault
ASR will switch off automatically in the event of a fault. Control indicator
R will illuminate in the instrument
cluster. Depending on version, a
corresponding message, e.g. ESP
unavailable , may also appear in the
Driver Information Centre 3 91.
Have the cause of the fault remedied by a workshop.
Control indicator R 3 86.
Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESC is operational after each engine
start as soon as control indicator R
extinguishes.
When ESC operates, R flashes.
The ESC system is automatically
activated when the vehicle is started
and cannot be deactivated.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.

Driving and operating131Fault
In the event of a fault, ESC will be automatically switched off and control indicator R will illuminate in the
instrument cluster. Depending on version, a corresponding message,
e.g. ESP unavailable , may also
appear in the Driver Information
Centre 3 91. The LED in the
ASR OFF button will also illuminate.
Have the cause of the fault remedied by a workshop.
Control indicator R 3 86.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds above approx.
30 km/h. Deviations from the stored
speeds may occur when driving uphill or downhill.
Activating in first gear is not possible.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
Switching on

132Driving and operatingTurn end of lever to the ON position;
control indicator m 3 91 illuminates in
the instrument cluster. Depending on
version, a corresponding message,
e.g. Cruise Control on , may also be
displayed in the Driver Information Centre 3 91.
Activation
Accelerate to the desired speed and
push lever upwards ( +); the current
speed is stored and maintained.
Accelerator pedal can be released.
Vehicle speed can be increased by depressing the accelerator pedal.
When the accelerator pedal is
released, the previously stored speed
is resumed.
Cruise control remains activated
while gearshifting.
Increase speed
With cruise control active, push lever
upwards ( +) or briefly push lever
upwards ( +) repeatedly: speed
increases continuously or in small
increments.Alternatively accelerate to the desired speed and store by pushing lever
upwards ( +).
Reduce speed With cruise control active, push lever
downwards ( -) or briefly push lever
downwards ( -) repeatedly; speed
decreases continuously or in small
increments.
Deactivation
Automatic deactivation: ● vehicle speed below approx. 30 km/h
● the brake pedal is depressed
● the clutch pedal is depressed
● the traction control system/Anti- Slip Regulator (ASR) or
Electronic Stability Control (ESC)
is operating
● the antilock brake system (ABS) is operating
Resume stored speed
Press = at a speed above 30 km/h.
The stored speed will be obtained.Switching off
Turn end of lever to the OFF position;
control indicator m extinguishes. The
stored speed is deleted. Switching off
the ignition also deletes the stored
speed.
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 parking assist system.
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles,
and giving acoustic signals.

Driving and operating133
The system consists of four ultrasonicparking sensors in the rear bumper.
Activation
The parking assist is turned on
automatically when reverse gear is
engaged.
The intervals between the beeps
become shorter as the vehicle gets
closer to the obstacle. When the
distance is less than 30 cm, the beeping is a continuous tone which
stops immediately when the distance
is increased.
Deactivation
The parking assist automatically
switches off when reverse gear is
disengaged.
Fault
In the event of a fault in the system,
r 3 86 illuminates in the instrument
cluster.
Depending on version, a
corresponding warning message,
e.g. Parking help unavailable , may
also be displayed in the Driver
Information Centre 3 91.
The following conditions could affect
the system's performance:
● The ultrasonic sensors are not clean. Keep the bumper free ofmud, dirt, snow, ice and slush.
● The sensors are covered by frost
or ice.
● The rear doors / tailgate are open.
● An object was hanging out of the
rear doors / tailgate during the
last drive cycle. Once the object
has been removed, the parking
assist will return to normal
operation.
● An object or cover is attached to the rear of the vehicle.
● The bumper is damaged. Take the vehicle to a workshop to
repair the system.
● Other conditions, such as vibrations from a jackhammer,
are affecting system
performance.
In the event the system still does not
work properly, seek the assistance of
a workshop.

134Driving and operatingA warning chime is also sounded
briefly if a fault is present when
reverse gear is engaged 3 96.
Note
The volume of the warning chime
can also be adjusted via the Driver
Information Centre 3 91.
Important hints for using the
parking assist systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention has to be paid to
low obstacles which can damage
the lower part of the bumper. If
such obstacles leave the detection area of the sensors during
approach of the vehicle, a
continuous warning tone will
sound.
Caution
Performance of the sensor can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
systems can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
vans). Object identification in the upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross section, like objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist will not avoid a
collision with objects which are out
of the detection range of the
sensors.
Note
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
The sensor may detect a non-
existent object (echo disturbance)
caused by external acoustic or
mechanical disturbances.
