Changing wheels
There may be a tyre repair kit instead of a
spare wheel – see page 256.
To ensure your safety, make the following
preparations and observe the following
information when changing wheels:
z Park the vehicle on a level, firm and non-
skid surface.
z Switch on hazard warning lights, apply
handbrake, automatic transmission 3 –
selector lever in P, manual transmission
or Easytronic 3 – engage 1st or reverse
gear.
z Correctly set up the warning triangle.
Warning triangle – see page 248.
z Take the spare wheel from the luggage
compartment.
z Before raising the vehicle, set the front
wheels to the straight-ahead position.
z On the Astra TwinTop, the roof must be
closed before the vehicle is raised.
z Slacken the wheel bolts one half turn
before raising the vehicle, but do not
totally unscrew the bolts.
z Never change more than one wheel at
once.
z Block the wheel diagonally opposite the
wheel to be changed by placing wedge
blocks or equivalent in front and behind
the wheel.
z Use the jack 3 only to change wheels.
z If the ground on which the vehicle is
standing is soft, a solid board (max. 1 cm
thick) should be placed under the jack 3.
Using a thicker board could damage the
jack 3 and the vehicle.
z No people or animals may be in the
vehicle when it is jacked up.
z Never crawl under a jacked-up vehicle.
z Do not start or run the engine while the
vehicle is on the jack.
z Fully tighten the wheel bolts after
lowering the vehicle all the way.
