Meanings:
e.g. 175/70 R 14 79 T
Speed code letters: Winter tyres 3
Instructions on fitting new tyres 3121.
Limitations 3191.
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.
Use of a spare wheel fitted with a summer
tyre may affect the vehicle’s driveability,
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 trims 3
The use of wheel trims and tyres that Opel
has approved for the vehicle and therefore
fulfill all requirements for the relevant
combination of wheels and tyres.
If the wheel trims and tyres used are not
Opel-approved, the tyres must not have a
beaded edge. Wheel trims must not impair brake cooling.
Remove the wheel trims if fitting tyre
chains3.

Tyre chains 3
Limitations 3191.
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). Remove the wheel trims when using tyre
chains 3137.
T y r e c h a i n s m a y o n l y b e u s e d a t s p e e d s u p
to 50 km/h. When travelling on roads that
are free of snow, they may only be used for
brief periods.
Tyre chains must not be used on the
temporary spare wheel. If you need to use
tyre chains after suffering a flat front tyre,
fit the temporary spare on the rear axle
and transfer one of the rear wheels to the
front axle.
Roof racks

For safety reasons and to avoid roof
damage we recommend using the Opel
roof rack system that is approved for your
vehicle.
Follow the usage instructions for the roof
rack.
Remove the roof rack when not in use.
Remove the covers from the roof rack
mounting apertures.
