Wheel-Changing - BMW 840Ci Owner's Handbook Manual

Changing a wheel
a
The car should ideally be posi-
tioned on a level, firm surface which
affords a good grip if a wheel is to be
changed. On a soft or slippery surface
(snow, ice, tiles or similar) the car or
the jack could slip sideways.
The car jack should likewise rest on a
firm surface.
Do not position wooden blocks etc.
beneath the jack, as its maximum load
capacity could otherwise be
exceeded. Never lie under the car or
start the engine when it is jacked up; a
very severe or fatal injury could result.
Additional safety precautions in the
event of a flat tyre:
Where possible, take the car off busy
roads and away from moving traffic.
Allow the steering lock to engage in
the straight-ahead position, apply the
handbrake and select first or reverse
gear or automatic transmission selec-
tor lever position P .
Switch on the hazard warning flashers
Request all occupants to leave the car
and to wait in a safe place (e.g. behind
roadside crash barriers).
If necessary, set up the warning trian-
gle or a flashing warning light at a suf-
ficient distance to the rear. Comply
with national legislation in these
respects.c
Jack
In the luggage compartment, behind
the left trim.
To avoid rattling noises later, note how
the various tools are attached to the
car and replace them in precisely the
same positions afterwards.
Pull the trim away at thr pre-formed cut-
out. Release the spring clip (arrow)
and take out the jack.
After use, lower the jack fully, place its
base in the holder and press it for-
wards.
Spare wheel and hexagon
adapter
These are both under the mat in the
luggage compartment. Take out the
mat.
Take off the black hexagon adapter,
unsrew the wing nut by hand and
remove the wheel.
