Hydraulic Brake Assist (HBA)
When the ESC function comes into action
and recognises any emergency situations
requiring hard braking, it automatically
delivers increased braking pressure to the
wheels.
Active Rollover Protection (ARP)
If the vehicle moves in an unstable manner,
this function helps the vehicle maintain
normal stability.
Trailer Stability Assist (TSA) 3
TSA monitors vehicle movements when
towing a caravan or trailer. If the system
detects lurching movements, engine power
is reduced and the vehicle/trailer
combination is selectiv ely braked until the
lurching ceases. DCS (Descent Control System)
The Descent Control System allows the
vehicle to travel at a low speed without
depressing the foot brake.
The vehicle will automatically decelerate to
a low speed and remain at that speed
when DCS button
5 is pressed.
Use only when descending steep grades
while driving off-road. Do not use when
driving on normal road surfaces.
Some noise or vibration from the brake
system may be apparent when DCS is
active. To activate
At speeds below approx. 50 km/h
(30 mph), press DCS button. The green DCS
control indicator
5 will flash in the
instrument panel, to show DCS is in
operation.
DCS will not activate at speeds above
50 km/h (30 mph), even if the button is
pressed.
Unnecessary usage of the DCS function,
such as while driving on normal roads, may
damage the brake system and the ESC
function.

(20 mph), or
z If the brake pedal is depressed, or
z If the clutch pedal 3 is depressed, or
z If the automatic transmission 3 selector
lever is in N, or
z If the traction control aspect of the
Electronic Stability Control (ESC) comes
into action, to limit wheel spin.
Resuming the stored speed
Press the c button at speeds above
30 km/h (20 mph); the speed selected
before cruise control was switched off, is

Tyre pressure monitoring system3
The tyre pressure monitoring system
continually checks the pressure of all four
wheels while driving.
A pressure sensor is integrated in each
wheel. Once a minute, the pressure of each
tyre is sent to a control unit, where it is
compared. If the system detects one or
more pressure differences, a message
appears on the information display.
Current tyre pressures can be shown in the
information display.
For the system to be operational, all wheels
must be equipped with pressure sensors
and all tyres must be filled to the
prescribed pressure. The tyre pressure
monitoring system automatically detects if
the vehicle is being driven with a load of up
to 3 persons or a full load.
Once the ignition is switched on, the system
is operational and will continuously
monitor the tyre pressures at speeds of
approx. 40 km/h (25 mph) and above. Tyre pressure – see pages 224.
Display of current tyre pressure
Select menu item Tyres from the Board
Computer menu.
The current pressure of each tyre is
displayed.
Warning messages
A message is given on the information
display to warn of inconsistent tyre
pressures. In some versions, the message is
displayed in abbreviated form.
For example, the following messages can
be displayed:
9 Warning
The tyre pressure monitoring system does
not replace manual checks with a
suitable gauge.
Check tyre pressures at least every
14 days and prior to any long journey:
the tyres should be checked when cold.
Don’t forget to check the spare. Ü Board Computer

speed. Check pressure at next opportunity
with appropriate gauge and correct if
necessary.
On the colour information display 3,
this report will appear in yellow. A graphic indicating the front left tyre is
shown together with the current tyre
pressure; significant pressure deviation or
direct pressure loss. Steer out of flow of
traffic as quickly as possible without
endangering other drivers. Stop and check
the tyres.
Mount the spare wheel if necessary –
see page 177.
On the colour information display
3,
this report will appear in red.

Brake system
The effectiveness of the brakes is an
important factor for traffic safety.
In the interest of effectiveness, do not
brake unnecessarily hard during the first
200 km (125 miles) after new disc brake
pads have been fitted.
Wear of the brake linings must not exceed
a specified limit. Regular maintenance, as
detailed on pages 206 to 212, is therefore
of the utmost importance for traffic safety.
Have worn brake pads replaced by a
workshop. Pads which have been tested
and passed ensure optimum brake
performance.
Brake pads worn to their minimum
thickness may generate a grinding noise.
It is possible to continue driving. Have your
brake pads replaced as soon as possible.
Seek the assistance of a workshop for
replacing the brake pads.

Hand brake
Always apply hand brake firmly. On slopes,
apply the hand brake as firmly as possible.
The mechanical hand brake acts on the
brakes on the rear wheels. It engages
automatically when applied.
To release the hand brake, press and hold
the button, pull the lever up slightly and
lower lever while holding the button in.
To reduce the operating forces of the
hand brake, depress the foot brake at the
same time. Control indicator
4 for brake system
Illuminates when ignition is switched on.
Extinguishes after engine is started.
Illuminates if hand brake is applied and/or
fluid level for brake hydraulics is too low.
Brake fluid level - see page 196. If the control indicator stays lit, the brakes
do not operate as normal or leaks are
found in the brake system, do not attempt
to drive the vehicle. Have the vehicle towed
to a workshop for inspection and repair.
If the control indicator does not illuminate
when the ignition is switched on or when
the hand brake is applied (with ignition
on), stop and consult a workshop.
9 Warning
If it illuminates when the hand brake is
not applied: stop vehi
cle, interrupt your
journey immediately.
Check brake fluid level and top-up if
necessary before consulting a workshop.
Have cause of brake fluid loss remedied.

Driving and operation148
Anti-lock Brake System (ABS)
u
The ABS continually monitors the vehicle's
brake system and prevents the wheels from
locking, irrespective of the road condition
and tyre grip.
It starts to regulate the braking pressure as
soon as a wheel shows a tendency to lock.
The vehicle remains steerable, even in the
event of very heavy braking, e.g. on bends
or when swerving to avoid an obstacle.
Even in the case of full-on braking, the ABS
makes it possible to drive round an
obstacle without releasing the brakes.
ABS control is made apparent through a
pulse in the brake pedal and the noise of
the regulation process. Control indicator
u for ABS
Illuminates in yellow for approx. 4 seconds
when the ignition is switched on.
At the same time, the system performs a
self-check. When the control indicator
extinguishes, the system is ready for
operation.
If the control indicato r does not illuminate
when the ignition is switched on, does not
extinguish after approx. 4 seconds, or if it
illuminates during driving, there is a fault in
the ABS. The vehicle's brake system may
remain operational without ABS
regulation. If control indicator
u illuminates during
driving along with brake system control
indicator 4, there is a serious fault in the
brake system. Have the system checked
immediately by a workshop.
Fault
You can continue driving, provided you
drive with care and anticipation.
Have the cause of the fault remedied by a
workshop. The system's integrated self-
diagnostics allows faults to be quickly
remedied.
9 Warning
For optimum braking, keep the brake
pedal fully depresse d throughout the
braking process, despite the fact that the
pedal is pulsating. Do not reduce the
pressure on the pedal.
Do not let this special safety feature
tempt you into taking risks when driving.
Traffic safety can only be achieved by
adopting a responsible driving style.
9 Warning
If there is a fault in the ABS, the wheels
may tend to lock in the event of unusually
heavy braking. This may cause the
vehicle to swerve. The benefits of the ABS
are lost.

Wheels, tyres
See page 223 for suitable tyres and
restrictions.
Factory-fitted tyres are matched to the
chassis and offer optimum driving comfort
and safety.
Changing tyre/wheel type
Note the necessary modifications before
switching to different tyres or wheels.
If wheel rims of a different type are to be
installed, the wheel nuts may also need to
be changed. We recommend you consult
an Opel Partner.
If tyres of a different size to those fitted at
the factory are used (this includes winter
tyres), the electron ic speedometer may
possibly need to be reprogrammed, to
ensure that the speed displayed is correct. Vehicles with tyre pressure monitoring
system
3
When using winter tyres, or when switching
to different tyre sizes, sensors for the tyre
pressure monitoring syst em can be fitted at
a later date by a workshop, upon request.
Otherwise, the system would not indicate
tyre pressure deviations.
Tyre pressure monitoring system -
see page 144.
Fitting new tyres
New tyres should be fitted in pairs, or, for
preference, in sets. Make sure that both
tyres on an axle are:
z the same size,
z the same design,
z the same make,
z and have the same tread pattern.
Fit directional tyres such that they roll in the
direction of travel. The rolling direction is
indicated by a symbol (e.g. an arrow) on
the sidewall.
Tyres fitted opposing the rolling direction
(e.g. when a tyre is changed) should be
refitted as soon as possible. This is the only
way to obtain full benefit from the design
properties of the tyre.
Observe legal requirements when
disposing of tyres. Some brands of tyres have a beaded edge
for alloy wheels, to protect against
damage. If wheel trims are used on steel
wheels with beaded-edge tyres, the
following procedure must be followed:
z
Wheel trims and tyres that are approved
by Opel for the respective vehicle and
comply with all of the relevant wheel and
tyre combination requ irements must be
used.
z If the wheel trims and tyres used are not
Opel-approved, the tyres must not have
a beaded edge.
9 Warning
Use of unsuitable tyres or wheels may
lead to accidents and render the vehicle
unroadworthy.
9 Warning
Use of unsuitable tyres or wheel trims
could lead to sudden pressure loss and
thereby accidents.
