148 Driving and operationCruise control 3
Cruise control can store and maintain
speeds of approx. 30 to 200 km/h.
Deviation from the stored speed is possible
on uphill or downhill inclines.
For safety reasons the cruise control
cannot be activated until the foot brake
has been operated once.
The cruise control is operated with the
buttons I, R and O on the turn signal lever.
Do not use the cruise control if it is not
advisable to maintain a constant speed
(e.g. in situations presenting a danger to
yourself and other road users, in heavy
traffic or on winding, slippery or greasy
roads). For manual transmission automated
3,
engage cruise control in automatic mode
only.

Hydraulic brake system 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, the brake pedal must be
depressed a considerable way before any
braking effect occurs, and much more
force is required. The braking distance is
longer. Contact a workshop for assistance
before continuing to drive. To ensure that full
pedal travel can be
utilised, especially in case of a fault in one
of the brake circuits, there must be no mats
in the vicinity of the pedals 3136.
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. This is especially important
to bear in mind when towing.
The brake fluid level should be checked
regularly. If the brake fluid level is too low
and the hand brake is not applied, control
indicator R on the instrument panel
illuminates 385.
Picture no: 17894s.tif
Brake system control indicator R
The control indicator illuminates after the
ignition is turned on, when the hand brake
is applied or if the brake or clutch fluid level
is too low. Brake fluid 3214.
9 Warning
If the control indicator illuminates when
the hand brake is released, stop driving
immediately. Contact a workshop for
assistance.

152 Driving and operationFor vehicles with manual transmission
automated 3, the control indicator flashes
for a few seconds when the ignition is
turned off when the hand brake is not
applied. Anti-lock brake system (ABS
u)
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 though a
pulse in the brake pedal and the noise of
the regulation process.
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.
Picture no: 17895s.tif
Control indicator u for ABS
It illuminates for a few seconds when
ignition is switched on. Once the control
indicator goes out, the system is ready for
operation.
If the control indica tor does not go out
after a few seconds, or if it illuminates while
driving, there is a fault in the ABS. The
brake system remains operational without
ABS regulation.
Adaptive brake lamp 3
During full-on braking, all three brake
lamps flash for the duration of ABS control. Self testing
When the engine is started and the vehicle
starts off, the system performs a self-check,
which may be audible.
Fault
Have cause of fault remedied by a
workshop. The system’s integrated self
diagnostics allow faults to be quickly
remedied.
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.

Hand brake Always apply hand brake firmly without
pressing the release button, and apply as
firmly as possible on steep slopes.
To release the hand brake pull lever up
slightly, press release button, and lower
lever all the way down.
To reduce the operating forces of the hand
brake, depress the foot brake at the same
time.
Brake assist If the brake pedal is operated quickly with
a powerful push, the vehicle is
automatically braked at full braking power
in order to achieve the shortest possible
braking distance when full-on braking
occurs (brake assist).
Maintain steady pressure on the brake
pedal for as long as full-on braking is to
continue. When the brake pedal is
released, the maximum brake force
amplification is taken away. Hill Start Assist
3 (HSA)
The system helps pull away on inclines.
After releasing the footbrake, if the hand
brake is not applied the brakes are only
released after 2 seconds. As soon as the
acceleration is sufficient to prevent rolling
back, the brake is released.
Wheels, tyresSuitable tyres and restrictions 3 228.
Tyres fitted in the factory are adapted to
the chassis and provide optimum driving
comfort and safety.
Changing tyre/wheel type
If tyres of a different size than those fitted
at the factory are used, it may be
necessary to reprogram the electronic
speedometer and make other vehicle
modifications.
After converting to a different tyre size,
have the adhesive label with tyre pressures
replaced.
9 Warning
Use of unsuitable tyres or wheels may
lead to accidents and render the vehicle
unroadworthy.

Driving and operation
Winter tyres 3
Notes on fitting new tyres 3 154.
Restrictions 3228.
Winter tyres improve driving safety at
temperatures below 7 C.
The design of summer tyres means they
have limited qualities for winter driving.
In accordance with country-specific
regulations, affix the speed sticker 3 in the
driver’s field of view.
If you use the spare wheel when it is fitted
with a summer tyre, the vehicle’s
driveability may be affected, especially on
slippery road surfaces. Obtain a
replacement for the faulty tyre as soon as
possible, and have the wheel balanced
and fitted to the vehicle.
Wheel covers 3
Use of wheel trims and tyres that approved
by Opel for the vehicle in question and
thereby fulfil all requirements for the wheel
and tyre combination.
If the wheel trims and tyres used are not
Opel-approved, the ty res must not have a
beaded edge. Wheel trims must not impair brake cooling.
Remove the wheel trims if fitting tyre
chains
3.
Picture no: 6459u.tif
Tyre chains 3
Restrictions and further information 3 228.
Tyre chains are only permitted on the
driven wheels (front axle). They must be
fitted to the tyres symmetrically in order to
achieve a concentric fit.
Always use fine mesh chains that add no
more than 10 mm to the tyre tread and the
inboard sides (including chain lock).
9 Warning
Use of unsuitable tyres or wheel trims
could lead to sudden loss of air and
thereby accidents.

the coupling ball bar. Close the socket
3 159, Fig. 15271 S.
9 Warning
Towing a caravan/trailer is only
permitted with a properly fitted coupling
ball bar. If the coupling ball bar cannot
be correctly fitted, please contact a
workshop for assistance.

164 Driving and operationIf the trailer/caravan starts to sway, drive
more slowly, do not attempt to correct the
steering and brake sharply if necessary.
If it is necessary to apply the brakes fully,
depress the brake pedal as hard as
possible.
Remember that the braking distance for
vehicles towing carava ns/trailers with and
without brake is always greater than that
for vehicles not towing a caravan/trailer.
When driving downhill , drive in the same
gear as if driving uphill and drive at a
similar speed.
Adjust tyre pressure to the value specified
for full load 3228. Starting on inclines
For vehicles with ma
nual transmission,
the most favourable engine speed
when starting off on an incline is
between 2500 and 3000 rpm for petrol
engines and between 2000 and 2500 rpm
for diesel engines. Hold engine speed
constant, engage clutch gradually (let slip)
– release hand brake – and open throttle. If
possible, the engine speed should not drop
during this procedure.
For vehicles with ma nual transmission
automated 3 in Automatic mode simply
apply full gas. Before starting off under extreme
operating conditions, switch off
unnecessary consumers.
