Catalytic converter, exhaust
gassesCatalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gas, such as carbon monoxide
(CO), hydrocarbons, (CH) and nitrous
oxide (NO
x). Fuel grades other than those listed on
pages 139, 220 (e. g. LRP = Lead
Replacement Petrol or leaded fuel) could
damage the catalytic converter or
electronic components.
z
In the event of misfiring, uneven engine
running, a clear reduction in engine
performance or other unusual problems,
have the cause of the fault rectified by a
workshop as soon as possible. In an
emergency, driving can be continued for
a short period, keeping vehicle speed
and engine speed low.
This does not apply when the Electronic
Stability Program (ESP®
Plus
3) kicks in
3 146.
z If unburnt fuel enters the catalytic
converter of a petrol engine, this may
result in overheating and irreparable
damage to the catalytic converter.
You should therefore avoid
unnecessarily long use of the starter
when starting off, running the tank dry
and starting the engine by pushing or
towing.
Picture no: 17875s.tif
Controlling exhaust emission
Design measures, primarily in the fuel
injection system and ignition system zones
in combination with the catalytic converter,
the amount of hazardous substances in the
exhaust emissions, such as carbon
monoxide (CO), hydrocarbons (CH) and
nitrogen oxides (NO
x), are reduced to a
minimum.
Caution
Damage to the catalytic converter or the
vehicle may result if the following points
are not observed.

146 Driving and operationDrive Control SystemsElectronic Stability Program (ESP®
Plus
) 3
ESP®
Plus
improves driving stability when
necessary in any driving situation
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.
ESP®
Plus
is ready for operation as soon as
the ignition is switched on and control
indicator v goes out.
When ESP®
Plus
comes into action, v
flashes. The vehicle is now in a critical situation;
ESP®
Plus
allows you to keep control of the
vehicle and reminds you to match your
speed to the road conditions.
9 Warning
Do not let this special safety feature
tempt you into taking risks when driving.
ESP®
Plus
does not negate the laws of
physics.
Adapt speed to the road conditions.

150 Driving and operationUltrasonic parking sensors 3
Park pilot makes reverse parking easier by
measuring the distance between the back
of the vehicle and obstacles to the rear. It is
the driver, however, who maintains full
responsibility for parking.
The system records the distance using four
sensors in the rear bumper.
To activate The park pilot system activates
automatically when the ignition is switched
on and reverse gear is engaged.
Operational readiness is indicated by a
brief tone.
If the vehicle approaches an obstacle, a
series of acoustic signals sound. The interval
between the signals be comes shorter as the
vehicle gets closer to the obstacle. When the
distance is less than 30 cm, the signal is
continuous.
Picture no: 14779s.tif
To deactivate The system deactivates automatically
when reverse gear is disengaged. Towing equipment, caravan/trailer towing
If a towing device is subsequently fitted to
the vehicle, the system must be set to the
modified vehicle length by a workshop.
When operating without a trailer, the tow
bar must be removed else the system can
be damaged.
Fitting rear load racks
3
Rear carriers, e. g. bike carriers, could
cause system malfunction.
Fault
On system faults, a permanent tone
sounds at a distance of 1 metre from the
obstacle. Have the cause of the fault
eliminated by a workshop.
In order to avoid operational problems or
erroneous information, the sensors must be
undamaged and free of soiling, snow and
ice.
9 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.

Driving and operation
Picture no: 14722s.tif
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.

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.

Self-help, vehicle care
General information
Depending on version, the spare wheel
may be in the form of a temporary spare
wheel 3. Refer to the notes on this page
and 3157, 3228.
On vehicles with alloy wheels 3 the spare
wheel may have a steel rim.
Use of a spare wheel together with winter
tyres could alter driving conditions. Have
the defective tyre replaced as soon as
possible.
Use of a spare wheel that is smaller than
the other wheels could alter driving
conditions. In many countries, it is only
permitted as a temporary spare wheel.
Have the defective tyre replaced as soon
as possible. Notes on temporary spare wheel
3
z The use of the temporary spare wheel
may affect the handling of the vehicle,
particularly if winter tyres are being
used 3. The Electronic Stability Program
ESP®
Plus
3 may switch itself off. Replace
defective tyre as soon as possible,
balance wheel and fit to vehicle.
z Fit only one temporary spare wheel.
z Do not drive faster than 80 km/h.
z Take curves slowly.
z Do not use the temporary spare wheel
for a lengthy period.
z Replace temporary spare wheel with full
specification wheel without delay.
z Tyre chains are not permitted on the
temporary spare wheel. If tyre chains
have to be used after a front wheel
puncture, fit tempor ary spare wheel to
the rear axle and fit a rear wheel to the
front axle. Check tyre pressure and
correct if necessary 3228.
z Observe notes on temporary spare
wheel on 3157, 3228. Notes on directional tyres
3
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.
The following applies to tyres fitted
opposing the rolling direction:
z Driving conditions may be altered. Have
the defective tyre replaced as soon as
possible.
z Do not drive faster than 80 km/h.
z Be especially careful when driving in rain
and snow.
