Accessories and vehicle modifications
We recommend the use of genuine
parts and accessories and factory approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products - even if they have a regulatory or
otherwise granted approval.
Any modification, conversion or other
changes made to standard vehicle specifications (including, without
limitation, software modifications,
modifications of the electronic control units) may invalidate the warranty
offered by Opel. Furthermore, such
changes may affect driver assistance
systems, may impact fuel
consumption, CO 2 emissions and
other emissions of the vehicle and
cause the vehicle to no longer
conform to the operating permit,
impacting the validity of your vehicle
registration.

Vehicle care165
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
is the same as before.
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
nominal tyre pressure and make
other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced. 3 1619 Warning
The use of unsuitable tyres or
wheels may lead to accidents and will invalidate the vehicle
operating permit.
Wheel covers
Wheel 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.
Vehicles with steel wheels: When
using locking wheel nuts, do not
attach wheel covers.
Tyre chains
Use tyre chains only on front wheels.

166Vehicle care9Warning
Damage may lead to tyre blowout.
Always use fine mesh chains that add
no more than 10 mm to the tyre tread
and the inboard sides (including chain
lock).
Tyre chains are only permitted on
tyres of size 205/60 R16 and
215/50 R17.
The use of tyre chains is not permitted on the temporary spare wheel.
Wheel changing
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 .
● 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.
● Clean wheel nuts and thread with
a clean cloth before mounting the wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
Jacking positions
The jacking positions shown refer to
the use of lifting arms and accessory
jacks used for changing winter /
summer tyres.
Rear arm position of the lifting
platform centrically under the recess
of the sill.

Vehicle care167Front arm position of the lifting
platform at the underbody.
Spare wheel
The spare wheel can be classified as
a temporary spare wheel depending
on the size compared to the other
mounted wheels and country
regulations. In this case a permissible maximum speed applies, even
though no label at the spare wheel
indicates this.
Only mount one temporary spare
wheel. Do not drive faster than
80 km/h. Take curves slowly. Do not
use for a long period of time.Caution
The use of a spare wheel that is smaller than the other wheels or in combination 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.
To remove: 1. Open the floor cover.
2. The spare wheel is secured with a
wing nut. Loosen nut to take out
the spare wheel.
Under the spare wheel there is the box with vehicle tools.
3. When, after a wheel change, no wheel is placed in the spare wheel
well, secure the tool box by
tightening the wing nut and close
the floor cover.
Fitting the spare wheel
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 orP .
● Remove the spare wheel 3 167.
● Never change more than one wheel at once.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre change.
● The jack is maintenance-free.
● 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.

Vehicle care169the jacking point in a manner thatprevents it from slipping.
Attach jack handle and with the
jack correctly aligned rotate handle until wheel is clear of theground.
5. Unscrew the wheel nuts.
6. Change the wheel.
7. Screw on the wheel nuts.
8. Lower the vehicle and remove jack.
9. Install the wheel wrench ensuring that it is located securely and
tighten each nut in a crosswise
sequence. Tightening torque is
140 Nm.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
Install centre cap on alloy wheels.
11. Install vehicle jacking point cover on versions with sill panels.
12. Stow the replaced wheel, the vehicle tools 3 159 and the
adapter for the locking wheel nuts 3 48.
13. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.Stowing a damaged full size
wheel in the spare wheel well
A damaged full size wheel must be
stowed outside up in the spare wheel
well secured with the wing nut.
The floor cover can be placed on the
projecting wheel.
Stowing the spare wheel back in
the well after replacing the
damaged wheel
1. Open the floor cover, loosen and remove wing nut.
2. Place the tools in the tool box or the tool bag 3 159.
