Vehicle care241
Set the jack to the necessary
height. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Attach jack handle and with the
jack correctly aligned rotate
handle until wheel is clear of the ground.
5. Unscrew the wheel nuts.
6. Change the wheel. Spare wheel 3 242.
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 panelling.
12. Stow the replaced wheel 3 242,
the vehicle tools 3 227 and the
adapter for the locking wheel nuts 3 60.
13. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.Have the defective tyre renewed or repaired as soon as possible.
Jacking position for lifting platform
Rear arm position of the lifting
platform centrically under the recess
of the sill.

Vehicle care251Remove dirt residues from smearing
wiper blades by using a soft cloth and
window cleaner. Also make sure to
remove any residues such as wax,
insect residues and similar from the
window.
Ice residues, pollution and continuous wiping on dry windows will damage or
even destroy the wiper blades.
Sunroof Never clean with solvents or abrasive
agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads. Do not apply wax or polishing
agents to the sunroof.
Glass panel Never clean with solvents or abrasive
agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads. Do not apply wax or polishing
agents to the glass panel.Wheels and tyres
Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damageRectify minor paintwork damage witha touch-up pen before rust forms.
Have more extensive damage or rust
areas repaired by a workshop.
Underbody Some areas of the vehicle underbody
have a PVC undercoating while other
critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.Before and after winter, wash the
underbody and have the protective
wax coating checked.
Liquid gas system9 Danger
Liquid gas is heavier than air and
can collect in sink points.
Take care when performing work
at the underbody in a pit.
For painting work and when using a
drying booth at a temperature above
60 °C, the liquid gas tank must be
removed.
Do not make any modifications to the
liquid gas system.
Towing equipment
Do not clean the coupling ball bar with a steam-jet or high-pressure jet
cleaner.
Air shutter Clean the shutter system in the front
bumper to maintain correct
functionality.

Customer information287Vehicle data recording
and privacy
Event data recorders Data storage modules in the
vehicle
A large number of electronic
components of your vehicle contain
data storage modules temporarily or
permanently storing technical data
about the condition of the vehicle,
events and errors. In general, this
technical information documents the
condition of parts, modules, systems
or the environment:
● operating conditions of system components (e.g. filling levels)
● status messages of the vehicle and its single components (e.g.
number of wheel revolutions / rotational speed, deceleration,
lateral acceleration)
● dysfunctions and defects in important system components● vehicle reactions in particulardriving situations ( e.g. inflation of
an airbag, activation of the
stability regulation system)
● environmental conditions (e.g. temperature)
These data are exclusively technical
and help identifying and correcting
errors as well as optimising vehicle
functions.
Motion profiles indicating travelled
routes cannot be created with these
data.
If services are used (e.g. repair
works, service processes, warranty
cases, quality assurance),
employees of the service network
(manufacturer included) are able to
read out this technical information
from the event and error data storage
modules applying special diagnostic
devices. If required, you will receive
further information at these
workshops. After an error has been
corrected, the data are deleted from
the error storage module or they are
constantly overwritten.When using the vehicle, situations
may occur in which these technical
data related to other information
(accident report, damages on the
vehicle, witness statements etc.) may
be associated with a specific person - possibly, with the assistance of an
expert.
Additional functions contractually
agreed upon with the client (e.g.
vehicle location in emergency cases)
allow the transmission of particular
vehicle data from the vehicle.
Radio Frequency
Identification (RFID)
RFID technology is used in some
vehicles for functions such as tyre
pressure monitoring and ignition
system security. It is also used in
connection with conveniences such
as radio remote controls for door
locking/unlocking and starting, and in-
vehicle transmitters for garage door
openers. RFID technology in Opel
vehicles does not use or record
personal information or link with any
other Opel system containing
personal information.
