Launch Control
Launch Control enables you to drive off with an
optimal vehicle acceleration on a high grip road
surface.
Do not use Launch Control too often
Do not use Launch Control too often, as
the higher loads on the vehicle lead to premature
component wear.◀
Launch Control is available when the engine is
at operating temperature, i.e., after driving con‐
tinuously for at least 6 miles/10 km.1.With the engine running, depress the brake
pedal with your left foot.2.Activate the SPORT+ program of the Dy‐
namic Driving Control, refer to page 82.3.With the vehicle stationary, activate manual
mode and select first gear.4.Press the accelerator all the way down. The
engine speed when driving off is controlled.
A flag symbol appears in the instrument
cluster.5.The vehicle accelerates when you release
the brake pedal. Keep the accelerator
pressed all the way down.6.The transmission shifts up automatically as
long as the accelerator is pressed all the way
down.
Launch Control only becomes available again
after a certain distance has been driven.
Launch Control can only be used after the
break-in phase, refer to page 108.
To maintain driving stability, activate DSC
whenever possible.
Manually releasing and engaging the
transmission lock
If a power failure occurs, e.g., if the battery is
discharged or disconnected, the transmission
lock must be released manually, otherwise the
rear wheels are blocked and the vehicle cannot
be towed.
Release the transmission lock manually for tow‐
ing only and set the parking brake beforehand to
prevent the vehicle from rolling. After parking
the vehicle, engage the transmission lock again
manually, refer to page 59.

Ensure that the floor mats are securely fastened
again when they are returned after being re‐
moved, such as for cleaning.◀
Driving in wet conditions
When roads are wet or there is heavy rain, briefly
exert gentle pressure on the brake pedal every
few miles.
Ensure that this action does not endanger other
road users.
The heat generated in this process helps dry the
brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the gear
in which the least braking is required. Otherwise,
the brake system may overheat, resulting in a
reduction in the brake system efficiency.
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
necessary.
Downshifting in manual mode of the 8-gear
Sport automatic transmission, refer to page 54.
Downshifting in manual mode of the 7-gear
Sport automatic transmission with dual clutch,
refer to page 57.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly even brake failure.◀
Do not drive in neutral
Never drive with the transmission in neu‐
tral, with the engine switched off or with the
clutch depressed; otherwise, you will have nei‐
ther the braking action of the engine or nor its
power assistance when braking or steering.◀Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked vehicle
When using the automatic climate control, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.
Loading Overloading the vehicle
To avoid exceeding the approved carrying
capacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden loss
of tire inflation pressure.◀
Secure heavy objects
Never transport unsecured heavy or hard
objects in the passenger compartment, as they
could be thrown around and pose a safety haz‐
ard to the vehicle's occupants during abrupt
braking or evasive maneuvers.◀
No fluids in the cargo area
Make sure that fluids do not leak into the
cargo area; otherwise, the vehicle may be dam‐
aged.◀

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
