2013 BMW Z4 traction control

When the maximum engine speed is reached,
the transmission automatically shifts up when
in M/S manual mode.
Shifting in manual mode▷To shift down: press the selector lever for‐
ward.▷To shift up: press the selector lever back‐
ward.
The gears are only shifted at a suitable engine
and vehicle speed, e.g. a downshift is not car‐
ried out at excessively high engine speeds.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the current gear.
Avoid automatic upshifting in M/S manual
mode
Gears are not shifted automatically, for in‐
stance at maximum engine speed, if one of the
following conditions is met:
▷DSC is deactivated.▷TRACTION is activated.▷SPORT+ is activated.
Dynamic Driving Control, refer to page 100
In addition, kickdown is disabled.
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 re‐
main 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 and the ve‐
hicle is not accelerated for a certain time,the system switches back into automatic
mode if the selector lever is in transmission
position D.▷Shift up: pull right shift paddle.▷Shift down: pull left shift paddle.
The vehicle only shifts up or down at appropri‐
ate engine and road speeds, e.g., it does not
shift down if the engine speed is too high.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the current gear.
Displays in the instrument cluster
The transmission position is displayed and the
engaged gear, such as M4, is displayed in
manual mode.

Driving stability control systemsVehicle equipmentThis 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
systems.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking.
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 short‐
est possible braking distance during full brak‐
ing. This system utilizes all of the benefits pro‐
vided 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. Sub‐
ject 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 100.
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 99Driving stability control systemsControls99

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 mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under 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.

Things to remember when drivingVehicle 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
systems.
Breaking-in period
General information Moving parts need to be broken in to adjust to
each other.
The following instructions will help achieve a
long vehicle life and good economy.
Engine and differential Always obey the official speed limits.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speeds:▷4,500 rpm and 100 mph/160 km/h.
Do not drive with full-throttle operation, and do
not use the transmission's kickdown mode or
Launch Control.
From 1,200 miles/2,000 km The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full
traction potential until after an initial breaking-
in period.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads and discs. Drive cautiously during this break-in
period.
Clutch
The clutch requires an initial break-in period of
approx. 300 miles/500 km to function at an op‐
timal level.
During this break-in period, engage the clutch
gently.
Following part replacement
The same breaking in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Ground clearance Limited ground clearance
Note that the Z4 sDrive35 has limited
ground clearance, for instance when driving
into underground parking garages or over ob‐
stacles. Otherwise, the vehicle may be dam‐
aged.◀
Closing the trunk lid Drive with the trunk lid closed
Only operate the vehicle with the trunk
lid closed; otherwise, exhaust fumes could en‐
ter the passenger compartment.◀Seite 128Driving tipsThings to remember when driving128

Tire Identification NumberTires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
DOT code:
DOT xxxx xxx 0313
xxxx: manufacturer code for the tire brand
xxx: tire size and tire design
0313: tire age
Tire age
The tire manufacturing date is contained in the
tire identification mark: DOT ... 0313 means
that the tire was manufactured in the week 3 of
2013.
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 oftheir use, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing 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 surfaces 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,
hydroplaning, 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.
Sustained high temperature can cause the ma‐
terial 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
possible tire failure.◀Seite 231Wheels and tiresMobility231
