Three LEDs indicate the highest temperature.
To switch off:
Press button longer.
If you continue driving within approx. the next 
15 minutes, the seat he ating is automatically 
activated at the previously set temperature.
The temperature is lowered or the heating is 
switched off entirely to  save on battery power. 
The LEDs stay lit.
Seat and mirror memory
You can store and call up two different combi-
nations of driver's seat and exterior mirror 
positions.
Settings for the backrest width and lumbar 
support are not stored in memory.
Storing
1. Switch on radio readin ess or the ignition, 
refer to page 61.
2. Adjust the seat and exterior mirrors to the 
desired positions. 3.

4. Press the desired memory button 1 or 2: 
the LED goes out.
Call-up
Do not call up the me mory while you are 
driving; otherwise, unexpected seat 
movement could result in an accident. <
Comfort function
1.Unlock and open the driver's door or switch 
on radio readiness, refer to page 61.
2. Briefly press the desired memory button 1 
or 2.
The adjusting procedure is halted when you 
touch a seat adjustment switch or one of 
the memory buttons.
Safety feature
1. Close the driver's door and switch the 
ignition on or off, refer to page 61.
2. Press the desired memory button 1 or 2 
and keep it pressed until the adjustment 
process has been completed.
If the  button was pr essed accidentally:
Press the button again; the LED goes out.
Safety belts
Observe the adjustment instructions on 
page 49 to ensure the best possible 
personal protection. <
Before every drive, make sure that all occupants

Vehicle equipment
In this chapter, all pr oduction, country, and 
optional equipment that is offered in the model 
range is described. As a result, some equip-
ment described may not be available in a partic-
ular vehicle, for example due to the options or 
national-market version  selected. This also 
applies to safety related functions and systems.
The right place for children
Do not leave children  unattended in the 
vehicle; otherwise, they could endanger 
themselves and/or other persons by opening 
the doors, for example. <
Children should always sit in the rear
Accident research has shown that the safest 
place for children is on the rear seat.
Children under the age of 13 or smaller 
than 5 ft/150 cm may be transported only 
in the rear in suitable child restraint systems 
appropriate for their age, weight and size. Oth-
erwise, there is an increase d risk of injury in the 
event of an accident. <
Children 13 years of age or older must be buck-
led in with a safety belt  as soon as there no 
longer is any child rest raint system that is 
appropriate for their age, size and weight.
Children in the front passenger seat
Should it be necessa ry to use a child 
restraint system on the front passenger 
seat, the front and side airbags for the front pas-
senger must be deactivated. Otherwise, a child 
traveling on that seat will face a significant risk 
of injury if the airbags are triggered off, even 
with a child restraint system. <
For more information on  automatic deactivation 
of the front passenger airbags refer to page 97.
Installing child restraint 
systems
Observe the child restraint system manu-
facturer's instructions when selecting, 
installing and using child restraint systems. 
Otherwise, the protective effect may be 
diminished.  <
Standard child restraint systems are designed 
to be secured with a lap be lt or with the lap-belt 
section of a lap-and-shou lder belt. Incorrectly 
or improperly installed child restraint systems 
can increase the risk of  injury to children. 
Always follow the installa tion instructions for 
the system with the greatest care.
On the front passenger seat
After installing a child restraint system on 
the front passenger seat, make sure that 
the front and side airb ags for the front passen-
ger are deactivated; ot herwise, there is an 
increased risk of injury if the airbags deploy.<
Seat position
Before installing a child restraint system, move 
the front passenger seat as far back and up as 
possible to obtain the best possible position for 
the belt. Do not change the seat position after 
this.
Backrest width
The backrest width of the front passenger 
seat must be at its widest possible set-
ting. Do not change the setting after installing 
the child seat; otherwise, the child seat's stabil-
ity on the front passenger seat is limited. <
1. Adjust the backrest width to its widest 
setting, refer to page 51.
2. Install the child seat.

MobilityWheels and tires
Tire identification marks
Knowledge of the labeling on the side of the tire 
makes it easier to identify and choose the right 
tires.
Tire size
Speed code letter
Q = up to 100 mph or 160 km/h
T = up to 118 mph or 190 km/h
H = up to 131 mph or 210 km/h
V = up to 150 mph or 240 km/h
W = up to 167 mph or 270 km/h
Y = up to 186 mph or 300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of 
the US Department of Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in 
the tire coding: DOT … 1013 means that the 
tire was manufactured in week 10 of 2013.
BMW recommends that you replace all tires 
after 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 betw een 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 Requir ements 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 conditio ns on a specified gov-
ernment test course. For example, a tire graded 
150 would wear one and one-half (1 γ) times as 
well on the government course as a tire graded 
100. The relative performance of tires depends 
upon the actual conditio ns 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. 
These grades represent the tire's ability to stop 
on wet pavement, as measured under con-
trolled conditions on specified government test 
surfaces of asphalt and concrete. A tire marked 
C may have poor traction performance.

Washing the vehicle
Notes
When using steam cleaners or high-pres-
sure cleaning jets, make sure to maintain 
a sufficient distance and stay below a maximum 
temperature of 140 7/60 6. 
Too close a distance, too high a pressure, or too 
high a temperature may cause damage or 
preliminary damage that  can then lead to long-
term damage.
Follow the operating inst ructions for the steam 
jet or high-pressure washer. <
When using high-pressure washers, do 
not spray the sensors, e.g. of the Park 
Distance Control, for an extended period and 
maintain a distance of at least 1 ft/30 cm from 
them. <
Regularly remove foreign objects, e.g. leaves, in 
the vicinity of the windsh ield when the hood is 
open.
Wash the vehicle more frequently, particularly 
in winter.
Heavy soiling and road salt can lead to vehicle 
damage.
Automatic car washes
Notes
In car washes with high pressures and 
nozzle positions, wate r may drip into the 
vehicle around the windows. <
Please note the following:
> Give preference to car washes that use 
cloth or soft brushes in order to avoid paint 
damage.
> Wheels and tires must not be damaged by 
transport devices.
> Fold in exterior mirror, refer to page 55; oth-
erwise, they can be damaged due to the 
width of the vehicle.
> Deactivate the rain sensor, refer to page 72, 
to prevent undesired wiper operation.
> In the convertible, do  not treat the top with 
wax. Ensure that a program is available that 
does not apply wax or is designed specifi-
cally for Convertibles.
> Move rear wiper into its wiper park position, 
deactivate it, and protect it from damage. 
Ask the car wash operator about suitable 
protective measures.
> Remove additional add-on parts, e.g. spoil-
ers or phone antennas, if they could be 
damaged.
> Unscrew the rod antenna.
> Leave the remote cont rol in the ignition 
lock.
Avoid car washes with guide rail heights 
over 4 in/10 cm; otherwise, there is the 
danger of damaging chassis parts. <
