Driving stability control systemsVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
Antilock Brake System ABS
ABS prevents locking of the wheels during brak‐
ing.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the shortest
possible braking distance during full braking.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.Dynamic Stability Control
DSC
The concept
DSC prevents traction loss in the driving wheels
when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes to the individual wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Do not reduce the additional safety margin with
a risky driving style, as otherwise there is a risk
of an accident.◀
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
bends.
To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC
Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the

indicator lamp for DSC lights up in the instru‐
ment cluster and DSC OFF is displayed. DTC
Dynamic Traction Control and DSC are deacti‐
vated together.
In the interest of better forward momentum,
brake intervention is performed in the manner of
a differential lock when the drive wheels spin
quickly even if DSC is deactivated.
Activating DSC Press the button.
DSC OFF and the indicator lamp in the
instrument cluster go out.
For better control The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC and
DTC has failed.
DSC deactivated: The indicator lamp lights up and
DSC OFF appears in the instrument
cluster.
DSC and DTC deactivated.
Dynamic Traction Control
DTC
The concept
The DTC system is a version of the DSC in which
forward momentum is optimized.
The system ensures maximum forward momen‐
tum on special road conditions, e.g., unplowed
snowy roads, but driving stability is limited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC un‐
der the following special circumstances:▷When driving in sand, on snowy inclines, in
slush, or on unplowed, snow-covered road
surfaces▷When rocking a vehicle free or starting off in
deep snow, sand, or on loose ground▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.
Activating DTC
Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for
DSC OFF lights up.

Deactivating DTCPress the button again.
TRACTION and the indicator lamp in
the instrument cluster go out.
For better control The indicator lamp flashes: DTC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC and
DTC has failed.
DTC activated: The indicator lamp lights up and TRAC‐
TION appears in the instrument cluster.
DTC is activated.
Performance Control
Performance Control enhances the agility of
your vehicle. To enhance performance during
sporty driving, the rear wheel on the inside of the
curve is braked while the resulting braking effect
is largely compensated by engine intervention.
xDrive
xDrive is the all-wheel-drive system of your ve‐
hicle. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv‐
ing characteristics. The 4-wheel drive system
xDrive variably distributes the drive forces to the
front and rear axle depending on the driving sit‐
uation and prevailing road conditions.
Hill Descent Control HDC
The concept
HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep down‐
hill gradients. Without requiring brake applica‐
tion, the vehicle moves at slightly more than
twice walking speed.
You can activate the Hill Descent Control at
speeds below approx. 22 mph/35 km/h. When
driving downhill at below approx.
22 mph/35 km/h, the vehicle reduces its speed
to approx. twice walking speed and keeps it con‐
stant.
While you are actively braking, the system is on
standby. The system does not brake the vehicle
during this time.
Increasing or reducing speed
The speed can be changed in the range from
roughly twice walking speed to approx.
15 mph/25 km/h by pressing the accelerator or
brake pedal lightly.
A target speed within the same range can be
specified using the lever of the cruise control.1Increasing speed2Decreasing speedSeite 96ControlsDriving stability control systems96

▷On bumps and rough roads, avoid contact
between the vehicle body and the ground.
The maximum ground clearance is 8 in‐
ches/20 cm and may vary with the loaded
cargo.▷When driving through water, do not exceed
the maximum water height of 12 in‐
ches/30 cm and drive at walking speed.▷After driving through water, press on the
brake pedal several times at low speeds to
dry the brakes.▷Depending on the prevailing terrain, activate
Dynamic Traction Control DTC, refer to
page 95, briefly.▷When the wheels spin, accelerate to enable
the driving stability control systems to dis‐
tribute the drive force to the individual
wheels.
After driving on poor roads
Adhere to the following points to ensure vehicle
safety:
▷Remove excessive accumulations of dirt
and mud from the vehicle body.▷Clear mud, snow, ice, etc., from the wheels
and tires and check for damage.Seite 129Things to remember when drivingDriving tips129

Tire Identification Number
Tires with DOT codes meet the guidelines of the
U.S. Department of Transportation.
DOT code:
DOT xxxx xxx 1012
xxxx: manufacturer code for the tire brand
xxx: tire size and tire design
1012: tire ageTire age
The tire manufacturing date is contained in the
tire identification mark: DOT ... 1012 means that
the tire was manufactured in the week 10 of
2012.
BMW recommends that you replace all tires af‐
ter 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
Conform to Federal Safety Requirements
All passenger car tires must conform to
Federal Safety Requirements in addition to
these grades.◀
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire graded
150 would wear one and one-half (1 1/2) times
as well on the government course as a tire
graded 100. The relative performance of tiresSeite 233Wheels and tiresMobility233
Online Edition for Part no. 01 40 2 914 595 - VI/12

depends upon the actual conditions of their use,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire’s ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfa‐
ces of asphalt and concrete. A tire marked C may
have poor traction performance.
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering, hydro‐
planing, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire’s resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sus‐
tained high temperature can cause the material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the laboratory
test wheel than the minimum required by law.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or in
combination, can cause heat buildup and pos‐
sible tire failure.◀RSC – Run-flat tires
The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall, refer to
page 236.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
XL
Designation for specially reinforced tires.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
There is an increased danger of hydroplaning if
the tread depth is less than 0.12 in/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the tire's
circumference and have the legally required
minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with TWI,
Tread Wear Indicator.
