on your vehicle to ensure that the
replacement or alternate tyres and wheels allow the tyre pressure
monitoring system to continue to
function properly.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory
approved repair kits can be used.
System initialisation After a wheel change or tyre pressure
adjustment the system must be
initialised: inflate the cold tyres to the
prescribed pressure according to the
tyre information label or this
document 3 217. Then switch on
ignition and press and hold the DDS
button for approx. 4 seconds. The
control indicator A flashes three
times.
If the tyre pressure difference
between the left and the right wheel
on one axle is more than 30 kPa, tyre
pressure monitoring system
malfunction will be indicated, as the
vehicle starts moving for the first time after initialisation. Adjust tyre
pressure and repeat initialisation.Notice
The system needs to be initialised
after tyre pressure change,
otherwise it will not be able to warn
properly.
Each time the tyres are replaced, the
tyre pressure monitoring system
sensors have to be dismounted and
serviced. For the screwed sensor
replace the valve core and sealing
ring, for the clipped sensor replace
complete rubber valve stem.
Auto learn function
After changing wheels the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
16 mph.
Tyre deflation detection
system The tyre deflation detection system
continually checks the rotation speed
of all four tyres.
If a tyre loses pressure the control
indicator w illuminates red. Stop
immediately and check tyre pressure.
Control indicator w 3 83.
176Vehicle care
System initialisation
After tyre pressure correction or
wheel change, the system must be
initiated: Switch on the ignition, press and hold the DDS button for approx.
4 seconds, control indicator w flashes
three times.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the wheels on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and
rear wheels periodically. Ensure that
the direction of rotation of the wheels
remains the same.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer and make other vehicle
modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Vehicle care177Wheel coversWheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Tyre chains
Tyre chains are only permitted on the
front wheels.
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
Damage may lead to tyre blowout.
Tyre chains are only permitted on tyre
sizes 175/70 R 14, 185/60 R 15,
185/65 R 15 2)
, 185/70 R 14,
195/55 R 16 2)
and 205/50 R16.
Tyre chains are only approved on
tyres of size 185/60 R 15 on vehicles
with a sports chassis. We recommend that you contact a workshop in order
to find out whether your vehicle is
equipped with a sports chassis.
Tyre chains are not permitted on tyre
sizes 195/60 R 15, 215/45 R 17 and
225/35 R18.
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at the tyre's side wall near the rim
cannot be repaired with the tyre repair kit.2) Not permitted when used as winter tyres.
Vehicle care183
General informationNotice
The driving characteristics of the
repaired tyre are severely affected, therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least
30 minutes.
The built-in safety valve opens at a
pressure of 7 bar (102 psi).
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.
Replace the used sealant bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
The adapters supplied can be used
to pump up other items e.g.
footballs, air mattresses, inflatable
dinghies etc. They are located on theunderside of the compressor. To
remove, screw on compressor air hose and withdraw adapter.
Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 177.
Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-skid surface. The front wheels
must be in the straight-ahead
position.
■ Apply the parking brake and engage first gear, reverse gear or
P .
■ Remove the spare wheel 3 185.
■ Never change more than one wheel
at a time.
■ Use the jack only to change wheels
in case of puncture, not for
seasonal winter or summer tyre
change.■ If the ground on which the vehicle is standing is soft, a solid board
(max. 1 cm thick) should be placed
under the jack.
■ Take heavy objects out of the vehicle before jacking up.
■ No people or animals may be in the
vehicle when it is jacked-up.
■ Never crawl under a jacked-up vehicle.
■ Do not start the vehicle when it is raised on the jack.
■ Before screwing in the wheel bolts,
clean them and lightly coat the
taper of each wheel bolt with
commercially available grease.
184Vehicle care
1. Pull off the wheel cover with thehook. Vehicle tools 3 170.
For wheel covers with visible
wheel bolts: The cover can remain
on the wheel. Do not remove the
retaining rings on the wheel bolts.
Alloy wheels: Disengage wheel
bolt caps with a suitable
screwdriver and remove. To
protect the wheel, place a soft
cloth between the screwdriver
and the alloy wheel.2. Install the wheel wrench ensuring that it locates securely and
slacken each bolt by half a turn.
The wheels might be protected by
locking wheel bolts. To loosen
these specific bolts first attach the
key adapter onto the head of the
bolt before installing the wheel
wrench. The key adapter is
located in the glovebox.3. Ensure the jack is positioned correctly with the vehicle jacking
points.
With versions of the Corsa VXR
with sill panelling or retrofitted sill
panelling, no jack must be used.
The vehicle may be damaged.

4. Set the jack to the necessaryheight. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Variant 1:Variant 2:
Attach jack handle and with the
jack correctly aligned rotate handle until wheel is clear of theground.
5. Unscrew the wheel bolts.
6. Change the wheel.
7. Screw in the wheel bolts.
8. Lower vehicle.
9. Install the wheel wrench ensuring that it locates securely and tighten
each bolt in a crosswise
sequence. Tightening torque is
110 Nm.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel bolt caps.
11. Stow the replaced wheel 3 177,
the vehicle tools 3 170 and the
key adapter 3 53.
12. Check the tyre pressure of the installed tyre and also the wheelbolt torque as soon as possible.
Have the defective tyre renewed or
repaired.
Spare wheel
Some vehicles are equipped with a
tyre repair kit instead of a spare
wheel.
186Vehicle care
If mounting a spare wheel, which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
The spare wheel has a steel rim.
Use of a spare wheel that is smaller
than the other wheels or together with winter tyres could affect driveability.
Have the defective tyre replaced as
soon as possible.The spare wheel is located in the load
compartment beneath the floor
covering. It is secured with a wing nut.
In the Corsa van the spare wheel is
screwed down together with the floor
cover. To lift the cover, undo the
plastic nut. There is a spacer between the spare wheel and the floor cover.
The spare wheel well is not designed
for all permitted tyre sizes. If a wheel
wider than the spare must be stowed
in the spare wheel well after changing wheels, the floor cover will be resting
against the protruding wheel. In vans
the spacer can be omitted if
necessary, or the wheel can be bolted
down without the floor cover.
Fitting a double load-bay floor in this
case in the upper position 3 66.
To remove, lift spare wheel, move to
a vertical position and remove from
above.
Temporary spare wheel Use of the temporary spare wheel
could affect driveability. Have the
defective tyre renewed or repaired as soon as possible.Only mount one temporary spare
wheel. The permissible maximum
speed on the label on the temporary
spare wheel is only valid for the
factory-fitted tyre size.
If your vehicle gets a flat tyre on the rear while towing another vehicle,
mount the temporary spare wheel in
the front and the full tyre in the rear.
Tyre chains 3 177.
Directional tyres
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:
■ Driveability may be affected. Have the defective tyre renewed or
repaired as soon as possible.
■ Drive particularly carefully on wet and snow-covered road surfaces.
Vehicle care189Towing
Towing the vehicle
Insert a suitable screwdriver in the
slot at the lower bend of the cap.
Release the cap by carefully moving
the screwdriver downwards.
Corsa VXR: Disengage and remove
cap by pressing on the lower part of
the cap.
The towing eye is stowed with the
vehicle tools 3 170 . The towing eye is
located in a recess.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for towing and not recovering the vehicle.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Transmission in neutral.Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
