2012 BMW Z4 SDRIVE35I traction control

Press button P.
Sport program and manual mode M/S
Activating the sport program
Push the selector lever to the left out of trans‐
mission position D.
The sport program is activated and DS is dis‐
played in the instrument cluster.
This position is recommended for a perform‐
ance-oriented driving style.
Activating manual mode
Push the selector lever to the left out of trans‐
mission position D.
Push the selector lever forward or backward.
Manual mode becomes active and the gear is
changed.
The engaged gear is displayed in the instrument
cluster, e.g., M1.
▷To shift down: press the selector lever for‐
ward.▷To shift up: press the selector lever back‐
ward.The transmission only shifts up or down if the
rpm and vehicle speed are appropriate. If the
engine speed is too high, the transmission does
not shift down.
The selected gear is briefly displayed in the in‐
strument panel, followed by the current gear.
Avoiding automatic upshifting
When the maximum engine speed is reached,
the transmission automatically shifts up when in
M/S manual mode.
These automatic shifting procedures are not
performed and kickdown is deactivated if one of
the following conditions is fulfilled:▷DSC is deactivated.▷TRACTION is activated.▷SPORT+ is activated.
Dynamic Driving Control, refer to page 82
Ending the sport program/manual
mode
Push the selector lever to the right.
D is displayed in the instrument cluster.
Shifting gears using the shift paddles
on the steering wheel
The shifting paddles make it possible to quickly
change gears since both hands can remain on
the steering wheel.
▷If the shift paddles on the steering wheel are
used to shift gears while in automatic mode
D, the transmission temporarily switches to
manual mode.▷If the shift paddles are not used to accelerate
or shift gears for a certain amount of time,
the transmission switches back to auto‐
matic mode D.
With the transmission position M/S selected,
the manual mode remains active.

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.
Dynamic Brake Control DBC
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.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Activating/deactivating DSC
DSC can be deactivated/activated via the DSC
OFF program of the Dynamic Driving Control,
refer to page 82.
For better control The DSC indicator lamp flashes: DSC is
controlling the drive forces and brake
forces.
The DSC indicator lamp lights up: DSC has
failed.Seite 81Driving stability control systemsControls81

Dynamic Traction Control
DTC
The concept
The DTC system and the TRACTION program
are a variant of the DSC in which forward mo‐
mentum 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 slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.
Deactivating/activating Dynamic
Traction Control DTC
The system and program can be deactivated/
activated via Dynamic Driving Control, refer to
page 83.
Dynamic Driving Control
The concept
Dynamic Driving Control can be used to adjust
the driving dynamics of the vehicle. Several pro‐
grams are available for this purpose; one pro‐
gram can be activated at a time using the Dy‐
namic Driving Control buttons.

To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC: DSC OFF Press the button for no longer than ap‐
prox. 10 seconds until the indicator
lamp for DSC OFF lights up in the instrument
cluster and DSC OFF appears in the instrument
cluster.

Tire Identification Number
Tires with DOT codes meet the guidelines of the
U.S. Department of Transportation.
DOT code:
DOT xxxx xxx 3311
xxxx: manufacturer code for the tire brand
xxx: tire size and tire design
3311: tire age
Tire age
The tire manufacturing date is contained in the
tire identification mark: DOT ... 3311 means that
the tire was manufactured in the week 33 of
2011.
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
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 (11/2) times
as well on the government course as a tire
graded 100. The relative performance of tires
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.◀Seite 159Wheels and tiresMobility159
