Switching off engine
Do not remove the remote control from
the ignition lock while the vehicle is roll-
ing, otherwise the steering-wheel lock would
engage while steering.
When leaving the vehicle, always take the
remote control with you.
When parking on a downhill incline, apply the
handbrake, otherwise the vehicle could roll
away.<
Manual transmission*
1.Briefly press the Start/Stop button with the
vehicle stopped.
2.Shift into first gear or reverse.
3.Apply the handbrake.
Sequential Manual Transmission with
Drivelogic
1.Apply the handbrake.
2.Engage a driving position.
3.Briefly press the Start/Stop button.
If N is engaged when switching off the
engine, this will be pointed out to you opti-
cally and acoustically.
Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is applied.
Indicator lamp for Canadian models.
Engaging
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
strongly. In doing so, continuously press the
button of the handbrake lever. Otherwise
excessive pressure can lead to the rear wheels
locking up and loss of traction – fishtailing – at
the rear axle.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<
Manual transmission*
While shifting in the 5th/6th gear lane,
press the gearshift lever toward the right,
otherwise accidental shifting into the 3rd or 4th
gear could result in engine damage.<
When engaging the 1st gear, a slight jolt may
occur. This is operation-related and no reason
for concern.

Technology for comfort, convenience and safety

DBC Dynamic Brake Control
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability Control
DSC optimizes vehicle stability and traction.
It also detects unstable driving states such as
understeering and oversteering, and helps
keep the vehicle on course within the physical
limits by reducing the engine output and by
braking at the wheels.
The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin further by taking risks.<
Indicator lamp
The indicator lamp goes out shortly
after the engine is started.
The indicator lamp flashes: DSC con-
trols the drive forces and brake forces.
The indicator lamp stays lit: DSC is deactivated.
M Dynamic Mode MDM
The M Dynamic Mode is a mode of the DSC
Dynamic Stability Control. It enables driving
with greater longitudinal and lateral accelera-
tion on dry road surfaces, however with limited
vehicle stability. The system does not provide
stabilizing intervention by reducing the engine
output and braking at the wheels until the abso-
lute driving limit is reached. Steering correc-
tions by the driver may also be required in this
driving state.
The M Dynamic Mode is deactivated each time
the engine is started.With the M Dynamic Mode activated, sta-
bilizing interventions are only carried out
to a reduced degree.<
To maintain vehicle stability, drive with
DSC activated and the M Dynamic Mode
deactivated whenever possible.<
Indicator lamp
The indicator lamp goes out shortly
after the engine is started. The indica-
tor lamp stays lit: M Dynamic Mode is
activated.
The indicator lamp lights up continuously and
the DSC indicator lamp flashes: the M Dynamic
Mode is active and controls the drive and brak-
ing forces.
Activating MDM
You activate the M Dynamic Mode with the
button on the steering wheel, refer to MDrive on
page50.
With the ignition switched on you can change
the settings of MDrive on the Control Display.
iDrive, for explanation of principle, refer to
page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Settings" and press the controller.
4.Select "Vehicle / Tires" and press the con-
troller.
5.Change to upper field if necessary. Turn the
controller until "MDrive" is selected and
press the controller.
6.Select "DSC" and press the controller.
7.Select "M Dynamic Mode" and press the
controller.

Wheels and tires
196 BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years. This also concerns the tire of the
spare wheel.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear 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 (1γ) 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, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics 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 sur-
faces 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, cor-
nering, hydroplaning, or peak traction charac-
teristics.<
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
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 Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm. At tread depths below 0.12 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
When winter tires wear down past a tread depth
of 0.16 in/4 mm, they become perceptibly less
