Note before adjusting
Never attempt to adjust your seat while 
the vehicle is moving. The seat could 
respond with unexpected movement, and the 
ensuing loss of vehicle control could lead to an 
accident. 
Also on the passenger side, do not incline the 
backrest too far to the rear while the vehicle is 
being driven, otherwise there is a danger in the 
event of an accident of sliding under the safety 
belt, eliminating the protection normally pro-
vided by the belt.<
Please follow the instructions on damage to 
safety belts provided on page53 and the infor-
mation on the active front head restraints
 on 
page51.
Adjusting seat
To ensure that the safety systems con-
tinue to provide optimized protection, 
please observe the adjustment instructions on 
page47.<

Lumbar support*
You can also adjust the contour of the backrest 
to obtain additional support in the lumbar 
region.
The upper hips and spinal column receive sup-
plementary support to help you maintain a 
relaxed, upright sitting position.
>Increase or decrease curvature: press front 
or rear section of switch.
>Shift curvature up or down: press upper or 
lowers section of switch.
Adjusting active backrest width*
First set a comfortable backrest width, see 
above. Based on the backrest width set, the lat-
eral support is automatically adapted to the cur-
rent driving situation.
The adaptation of the backrest width and the 
speed of the adjustment vary depending on the 
program. You can select from among three pro-
grams from comfort to sport.

Storing the mirror positions, refer to Seat, mir-
ror and steering wheel memory on page49.
Adjusting manually
You can also adjust the mirrors manually by 
pressing against the outer edges of their mirror 
glass.
Folding mirrors in and out*
Pressing button3 allows you to fold mirrors 
in and out up to a speed of approx. 20 mph/
30 km/h. This is advantageous, for example, in 
car washes, narrow streets or for bringing mir-
r o r s  t h a t  ha v e  b e e n  m a nu ally folded in back into 
the correct position. Mirrors that were folded in 
are folded out automatically at a speed of 
approx. 25 mph/40 km/h.
Before going through a car wash, fold the 
mirrors in manually, or with button 3, oth-
erwise they could be damaged, depending on 
the width of the car wash system.<
Automatic heating
Below a certain outdoor temperature, both 
exterior mirrors are heated whenever the 
engine is running or the ignition is switched on.
Tilting down passenger-side exterior 
mirror – automatic curb monitor*
Activating
1.Slide switch into the driver's side mirror 
position, arrow 1.
2.Shift into reverse or move selector lever into 
position R. 
The mirror glass tilts downward somewhat 
on the passenger's side. This allows the 
driver to see the area immediately adjacent 
to the vehicle – such as a curb – when park-
ing, etc.
Deactivating
Slide switch into the passenger side mirror 
position, arrow 2.

Transporting children safely
The right place for children
Do not leave children unattended in the 
vehicle, otherwise they could endanger 
themselves and other persons, e.g. by opening 
the doors.<
Children always in the rear
Accident research shows that the safest place 
for children is on the rear seat.
Children younger than 13 years of age or 
with a height under 5 ft/150 cm may only 
be transported in the rear in child restraint sys-
tems which correspond to the age, weight and 
height of the child. Otherwise there is an 
increased danger of injury in an accident.<
Children 13 years of age or older must wear a 
safety belt as soon as a suitable child restraint 
system can no longer be used due to their age, 
size and weight.
Exception for front passenger seat
Should it ever be necessary to use a child 
restraint system on the front passenger 
seat, the front and side airbags on the passen-
ger side must first be deactivated. Otherwise, 
there is an increased risk of injury for the child if 
the airbags are triggered, even with a child 
restraint system.<
For more information on automatic deactivation 
of the front passenger airbags, refer to 
page101.
Installing child restraint 
systems
Observe the child restraint system manu-
facturer's instructions for selection, 
installation and use of the child restraint sys-
tems. Otherwise the degree of protection may 
be reduced.<
Backrest width* on front passenger 
seat
Open the backrest width setting of the 
front passenger seat all the way. After 
mounting the child's seat, deactivate the active 
backrest width adjustment and do not call up 
any memory position. Otherwise this limits the 
stability of the child's seat on the front passen-
ger seat.<
1.After unlocking the vehicle, sit on the front 
passenger seat and close the door to call up 
the memory position.
2.Completely open the backrest width adjust-
ment, refer to page48.
3.Deactivate active backrest width adjust-
ment, refer to page49.
4.Install child's seat.
Child seat security
All rear safety belts and the safety belt for the 
front passenger can be locked against pulling 
out to secure child restraint systems.
Locking safety belt
1.Secure the child restraint system with the 
belt.
2.Pull out the belt webbing completely.
3.Allow the belt webbing to retract and pull 
taut against the child restraint system. The 
safety belt is locked. 

Things to remember when driving
136 the road surface, ultimately undermining your 
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread 
depth of the tires decreases, refer also to Mini-
mum tire tread on page229.
Driving through water
Do not drive through water on the road if it 
is deeper than 1 ft/30 cm, and then only at 
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the 
transmission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle in 
place for a long time by riding the clutch; 
use the handbrake. Otherwise greater clutch 
wear will result.<
Braking safely
Your BMW is equipped with ABS as a standard 
feature. In situations that require it, it is best to 
brake with full force. Since the vehicle maintains 
steering responsiveness, you can still avoid 
possible obstacles with a minimum of steering 
effort.
Pulsation of the brake pedal, combined with 
sounds from the hydraulic circuits, indicate that 
ABS is in its active mode.
Do not drive with your foot resting on the 
brake pedal. Even light but consistent 
pedal pressure can lead to high temperatures, 
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain, 
briefly exert gentle pressure on the brake pedal 
every few miles. Monitor traffic conditions to 
ensure that this maneuver does not endanger 
other road users. The heat generated in this 
process helps dry the pads and rotors to ensure 
that full braking efficiency will then be available 
when you need it.
Hills
To prevent overheating and the resulting 
reduced efficiency of the brake system, drive long or steep downhill gradients in the 
gear in which the least braking is required. Even 
light but consistent pressure on the brake can 
lead to high temperatures, brake wear and pos-
sibly even brake failure.<
The braking effect of the engine can be further 
increased by downshifting, if necessary all the 
way down into first gear. This strategy helps 
you avoid placing excessive loads on the brake 
system. For information on downshifting in the 
manual mode of the automatic transmission, 
refer to page65.
Do not drive with the clutch depressed, in 
idle or with the engine switched off, other-
wise there will be no engine braking action or 
support of the braking force and steering. 
Never allow floor mats, carpets or any other 
objects to protrude into the area of movement 
of the pedals and impair their operation.<
Corrosion on brake rotors
When the vehicle is driven only occasionally, 
during extended periods when the vehicle is not 
used at all, and in operating conditions where 
brake applications are less frequent, there is an 
increased tendency for corrosion to form on 
rotors, while contaminants accumulate on the 
brake pads. This occurs because the minimum 
pressure which must be exerted by the pads 
during brake applications to clean the rotors is 
not reached.
Should corrosion form on the brake rotors, the 
brakes will tend to respond with a pulsating 
effect that even extended application will fail to 
cure.
When vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the 
vehicle. Traces of condensed water under the 
vehicle are therefore normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page55, 
otherwise they could be damaged due to the 
width of the vehicle.

Wheels and tires
228 DOT code:
Tire age
The manufacturing date of tires is contained in 
the tire coding: DOT ...1008 indicates that the 
tire was manufactured in week 10 of 2008.
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 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. 
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.
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.<
RSC – run-flat tires
You will recognize run-flat tires by a circular 
symbol containing the letters RSC on the side 
of the tire, refer to page229.
M+S
Winter and all-season tires. 
These have better winter properties than sum-
mer tires. e.g.
