Under the hood
Never attempt to perform any service or
repair operations on your vehicle without
the required professional technical training. If
you do not know what repair procedures to fol-
low, have work on your vehicle done only by
your BMW Sports Activity Vehicle Center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. If this work is not carried out properly,
there is a danger of subsequent damage and
related safety hazards.<
Hood
Releasing
Pull lever.
Opening
Press the release handle and open the hood.
Closing
Close the hood from a height of approx. 16 in/
40 cm with momentum. It must be clearly heard
to engage.
Make sure that the closing path of the
hood is clear, otherwise injuries may
result.
If you see any signs that the hood is not com-
pletely closed while driving your vehicle, you
should stop at once and close it securely.<

Replacing components
252
Removing compact wheel
The compact wheel is located in the cargo bay
under the floor panel.
1.Remove the tool mount.
2.Unscrew the wing nut 1.
3.Remove the washer 2 laterally.
4.Remove the compact wheel.
Preparing wheel change
1.Observe the safety precautions above.
2.Loosen the lug bolts a half turn.
Jacking up vehicle
1.Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base rests on the ground
perpendicularly beneath the jacking point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.<2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to illustration detail.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.
3.Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the
lug bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. Otherwise, incorrectly tight-
ened lug bolts are a hidden safety risk. The
tightening torque is 101 lb ft/140 Nm.<
2.Stow the defective wheel in the cargo bay.
The defective wheel cannot be stored
under the floor panel flap due to its
size.<

Replacing components
254
