For almost all conditions, the AUTO program 7
offers the optimum air distribution and air flow
rate, refer to AUTO programs below. Select a
comfortable interior temperature only.
The following sections contain more detailed in‐
formation on the available setting options.
Most of these settings are stored for the remote
control currently in use, Personal Profile set‐
tings, refer to page 21.
Air distribution, manual
Depending on the selected setting, the air is di‐
rected to the windshield, to the upper body area,
to the knee area and into the footwell.
Adjusting air distribution manually Press the button repeatedly until
the air distribution is set as re‐
quired. The corresponding LED lights up.
The manual air distribution is also switched on
when the AUTO program is deactivated.Temperature
Set the desired temperatures indi‐
vidually for the driver's and passen‐
ger sides.
The automatic climate control ach‐
ieves this temperature as quickly as possible re‐
gardless of the season, using maximum cooling
or heating power if necessary, and then main‐
tains it.
To give the automatic climate control enough
time to achieve the set temperature, do not
switch between different temperature settings
in quick succession.
Maximum heating power can be obtained with
the highest setting, regardless of the external
temperature.
The lowest setting effects continuous cooling.Seite 92ControlsClimate92

Switching the cooling function on and
off
The cooling function cools and de‐
humidifies the incoming air before
reheating it as required, according
to the temperature setting. This
function is only available while the
engine is running.
The cooling function helps to prevent conden‐
sation on the windows or to remove it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is switched on automati‐
cally with the AUTO program.
Maximum cooling The air is cooled as quickly as pos‐
sible with the engine running.
The automatic climate control goes into recir‐
culated air mode at the lowest temperature. Air
flows at maximum rate from the vents for the
upper body area. You should therefore open the
vents for maximum cooling.
AUTO program
The AUTO program automatically adjusts the air
distribution to the windshield and side windows,
toward the upper body area, and into the foot‐
well and knee area.
The air flow rate and air distribution, in addition
to your temperature specifications, will be
adapted to outside influences as a result of sea‐
sonal changes, e.g., sunlight or window conden‐
sation.
The cooling function is switched on automati‐
cally with the AUTO program.
Switching on/off Press the button.Manual air distribution and air flow rate are acti‐
vated when the AUTO program is deactivated.
AUTO program climate level
The climate levels can be used to vary the in‐
tensity when the AUTO program is switched on.
For example, air flow is adjusted automatically
to optimize climate control.
When the AUTO program is
switched on, the climate level of the
AUTO program can be selected us‐
ing the buttons for controlling the manual air
flow rate.
The selected climate level is displayed by an
LED.
Convertible program
When the hardtop is open, the convertible pro‐
gram is activated as well. In the convertible pro‐
gram, the automatic climate control is optimized
for driving with the hardtop open. In addition, the
air flow rate is increased as vehicle speed in‐
creases.
The effectiveness of the convertible program
can be enhanced considerably by installing the
wind deflector.
Adjusting air flow rate manually Press the left side of the button to
reduce air flow. Press the right side
of the button to increase it.
The air volume may be reduced automatically to
save battery power. The display remains the
same.
Switching the system on/off
With the blower at its lowest setting, press the
left side of the button to switch off the automatic
climate control. All displays are cleared except
for the rear window defroster if it is switched on.Seite 93ClimateControls93

Press any button except the rear window de‐
froster to reactivate the automatic climate con‐
trol.
Residual heat
The heat stored in the engine is used to heat the
interior.
This function can be switched on
using the right-hand button under
the following conditions:▷Up to 15 minutes after switching off the en‐
gine.▷When the engine is warm.▷With sufficient battery voltage.▷At an external temperature under 77 ℉/
25 ℃.
The middle LED is lit when the function is on.
Automatic recirculated air mode/
recirculated air mode
Switch on the desired operating
mode by pressing this button re‐
peatedly:
▷LED off: outside air flows in
continuously.▷Left LED on, automatic recirculated air con‐
trol: a sensor detects pollutants in the out‐
side air. If necessary, the system blocks the
supply of outside air and recirculates the in‐
side air. As soon as the concentration of pol‐
lutants in the outside air has decreased suf‐
ficiently, the system automatically switches
back to outside air supply.▷Right LED on, recirculated air mode: the
supply of outside air into the vehicle is per‐
manently blocked. The system then recir‐
culates the air currently within the vehicle.
Only use recirculated air mode for a limited
period
If condensation starts to form on the inside win‐
dow surfaces during operation in the recircu‐
lated air mode, you should switch it off while also
increasing the air flow rate as required. The re‐
circulated air mode should not be used for an
extended period of time, as the air quality inside
the vehicle deteriorates steadily.◀
Defrosting and defogging windows Quickly removes ice and conden‐
sation from the windshield and
front side windows.
For this purpose, also switch on the cooling
function.
Rear window defroster The defroster switches off auto‐
matically after a certain time or
when the hardtop is opened.
Ventilation1Use the lever to change the direction of the
air flow2Use the thumbwheels to smoothly open and
close the air vents3Thumbwheel for adjusting the amount of
cool air from the vents to the upper body
area. This can be used to adjust the air tem‐
perature for the upper body area.
Ventilation for cooling
Adjust the vents to direct the flow of cool air in
your direction, for instance if the interior has be‐
come too warm.

Draft-free ventilation
Adjust the vents to let the air flow past you.
Microfilter/activated-charcoal filter
The microfilter traps dust and pollen in the in‐
coming air. The activated-charcoal filter pro‐
vides additional protection by filtering gaseous
pollutants from the outside air. Your service cen‐
ter replaces this combined filter during routine
maintenance.Seite 95ClimateControls95

If the vehicle must be driven with the trunk lid
open:1.Close all windows.2.Greatly increase the air flow rate of the air
conditioner or automatic climate control.
Hot exhaust system
Hot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that flammable materials, e. g. hay, leaves, grass,
etc. do not come in contact with the hot exhaust
system during driving, while in idle position
mode, or when parked. Such contact could lead
to a fire, and with it the risk of serious personal
injury as well as property damage.
Do not touch hot exhaust pipes; otherwise, there
is the danger of getting burned.◀
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is not recommended to use mobile phones,
such as mobile phones without a direct connec‐
tion to an external aerial in the vehicle's passen‐
ger compartment. Otherwise, the vehicle elec‐
tronics and mobile communication devices can
interfere with each other. In addition, there is no
assurance that the radiation generated during
transmission will be discharged from the vehicle
interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
Driving through water
Drive though calm water only if it is not deeper
than 9.8 inches/25 cm and at this height, no
faster than walking speed, up to 6 mph/10 km/h.
Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the elec‐
trical systems and the transmission may be
damaged.◀
Braking safely
Your vehicle is equipped with ABS as a standard
feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsiveness.
You can still avoid any obstacles with a minimum
of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
Objects in the area around the pedals No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved for
the vehicle and can be properly fixed in place.Seite 109Things to remember when drivingDriving tips109
Online Edition for Part no. 01 40 2 609 184 - 09 11 500

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.◀

Close both windows
An open window causes higher air resistance
and thus increases fuel consumption.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire inflation
pressure, refer to page 155, at least twice a
month and before starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehicle
driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.
Avoid high engine speeds
Use 1st gear to get the vehicle in motion. Be‐
ginning with 2nd gear, accelerate rapidly. When
accelerating, shift up before reaching high en‐
gine speeds.
When you reach the desired speed, shift into the
highest applicable gear and drive with the en‐
gine speed as low as possible and at a constant
speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use coasting conditions
When approaching a red light, take your foot off
the accelerator and coast to a halt in the highest
applicable gear.On a downhill slope, take your foot off the ac‐
celerator and coast in a suitable gear.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer
stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Fuel savings are achieved after the vehicle is
switched off for only approx. 4 seconds.
The Automatic Engine Start/Stop Function au‐
tomatically switches the engine off during a
stop. Additional information on the Automatic
Engine Start/Stop Function, refer to page 47.
Switch off any functions that are not
currently needed
Functions such as the automatic climate control
require a large amount of energy and consume
additional fuel, especially in city and stop-and-
go traffic.
Therefore, switch off these functions if they are
not actually needed.
Have maintenance carried out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
Have the maintenance carried out by your serv‐
ice center.
Please also note the BMW Maintenance Sys‐
tem, refer to page 168.Seite 113Things to remember when drivingDriving tips113

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
