EBV Electronic brake-force
distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.
DSC Dynamic Stability Control
The system optimizes vehicle stability dur-
ing acceleration and when starting from a
full stop, as well as optimizing traction.
The system recognizes any tendency for
the vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimized
stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC contains the functions
DTC Dynamic Traction Control and DBC
Dynamic Brake Control.
Indicator lamp
The indicator lamp goes out shortly
after the engine starts.
The indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off using the Con-
trol Center.
Activating DTC Dynamic Traction
Control
In particular driving situations, in deep
snow, for example, DTC ensures the maxi-
mum forward momentum. The gain in for-
ward momentum in these situations
involves a reduction in vehicle stability.
DTC is active up to 45 mph/70 km/h.You may find it useful to briefly activate
DTC under the following special circum-
stances:
>When rocking the vehicle and starting
off in deep snow or on loose road sur-
faces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
Select "Settings". Select "DTC" and con-
firm your selection. DTC is now activated.
The DTC indicator lamp in the Info Display
lights up permanently.
When DTC is active, DSC provides
only limited system response up to a
speed of approximately 45 mph/70 km/h.
Intervention for stability enhancement is
reduced.<
Deactivating DTC again
Select "Settings". Select "DTC" and con-
firm your selection. DTC is now deacti-
vated. The DTC indicator lamp in the Info
Display goes out. DSC is once again avail-
able without restriction.

Grasp the handle in the upper panel and
fold it down.
Undo the wingnut and remove the jack.
After use, screw the jack all the way
back down and snap the handle back
into place.
Spare tire
1.Unscrew the wing nut 1
2.Remove the disc 2 to the side
3.Completely unscrew the threaded rod 3
4.Remove the spare tire.
Preparing wheel change
1.Read carefully and comply with the
safety precautions on page204
2.Secure the vehicle to prevent it from
rolling:
Place the wheel chock against the rear
surface of the front tire on the side
opposite the side being raised. If the
vehicle is parked on a downward slope,
place the wheel chock securely in front
of the tire. On a steep grade, also
secure the vehicle against rolling
3.Loosen the lug bolts 1/2 a turn.
Lifting vehicle
1.Position the jack at the jacking point
closes to the wheel so that the entire
jack base makes contact vertically
under 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 crank-
ing up the jack, refer to section of illus-
tration
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. Clean the lug bolts
3.Position the wheel or spare tire on the
hub and screw in at least two bolts
diagonally.
When you mount wheels other than
Genuine BMW light-alloy wheels, differ-
ent lug bolts may also be required
4.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
5.Lower the vehicle and remove the jack
from beneath the vehicle.
Following installation
1.Tighten the lug bolts in a diagonal pat-
tern
To ensure safety, always have the
lug bolts checked with a cali-
brated torque wrench as soon as possi-
ble to ensure that they are tightened to
the specified torque. The tightening
torque is 140 Nm.<
2.Reverse the removal sequence when
storing the wheel and tools in the vehi-
cle
