Minimum fuel grade
BMW recommends AKI 89.
Do not use gasoline below the indicated
minimum fuel grade; otherwise, proper
engine function is not ensured. <
If you use gasoline with this minimum AKI rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
The use of poor-quality fuels may result in
harmful engine deposits or damage.
Additionally, problems re lating to drivability,
starting and stalling may occur, especially
under certain environmental conditions such as
high ambient temperatur e and high altitude.
If drivability problems are encountered, we rec-
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI number
— for a few tank fills. To avoid harmful engine
deposits, we highly recommend purchasing
gasoline from BP or Top Tier retailers.
Failure to comply with these recommendations
may result in th e need for unscheduled mainte-
nance. <

Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi
cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Tire inflation pressures
Information for your safety
It is not merely the tire s' service life, but also
driving comfort and, to a great extent, driving
safety that depend on th e condition of the tires
and the maintenance of the specified tire
pressure.
Check the tire inflation pressure regularly
and correct it, if nece ssary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
run-flat tires. A flat tire will seriously impair your
vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to loss of
control over the vehicle. <
Checking pressure
Only check tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure is higher.
After correcting the tire inflation pressure,
reset the Tire Pressure Monitor, refer to
page 103, or reinitialize the Flat Tire Monitor,
refer to page 100.<
Inflation pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressure s apply to the tire
sizes approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center. <
For correct identificati on of the right tire
inflation pressures, observe the following:
> Tire sizes for your vehicle
> Maximum allowable driving speed

Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respecti ve tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100 mph or 160 km/h.
These tire inflation pre ssures can also be found
on the driver's side door pillar when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed; otherwise,
tire damage and accidents could occur. <
Tire inflation pressures for driving
above 100 mph or 160 km/h
In order to drive at maximum speeds in
excess of 100 mph or 160 km/h, adjust
pressures to the respecti ve tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds including those
exceeding 100 mph or 160 km/h. Otherwise,
tire damage and accidents could occur. <
Observe all national an d local maximum speed
limits; otherwise, violations of the laws could
occur.

Wheels and tires
Mobility
The traction grade assigned to this tire is
based on straight-ahe
ad braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics. <
Temperature
The temperature grades are A, the highest, B,
and C, representing the ti re'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 whee l 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 exce ssive loading, either
separately or in combin ation, 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 page252.
M+S
Winter and all-season tires.
These have better wint er properties than
summer tires.
XL
Designation for specia lly 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 be come perceptibly less
suitable for winter condit ions. In the interest of
safety, new tires sh ould be installed.
Wear indicators in the base of the tread groove
are distributed around th e tire's circumference;
the letters TWI, for Tread Wear Indicator, on the
tire's sidewalls identify tires that incorporate
these wear indicators. On ce the tire tread has
worn down to the wear indicators, the tire has
worn to a depth of 0.063 in/1.6 mm.
Wheel/tire damage
Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles can
cause serious damage to wheels, tires, and sus-
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and th e road. Be careful to
avoid road hazards and reduce your speed,
especially if your vehi cle is equipped with low-
profile tires.

MobilityWheels and tires
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so , drive carefully to the
nearest BMW center or tire dealer. If necessary,
have the vehicle towed there.
O t h e r w i s e , t i r e d a m a g e c a n p o s e a l e t h a l h a z a r d
to vehicle occupants and other road users. <
Tire age
For various reasons, such as the development
of brittleness, BMW recommends tire replace-
ment after no more than 6 years, regardless of
the actual wear of the tires.
The manufacturing date of tires is contained in
the tire coding:
DOT ... 1013 means that the tire was manufac-
tured in week 10 of 2013.
New wheels and tires
Have new wheels and tires mounted only
by your BMW center or by a tire dealer. If
this work is not carried out properly, there is a
danger of subsequent damage and related
safety hazards. Make sure that the new wheels
are balanced. <
Retreaded tires
BMW recommends that you do not use
retreaded tires, since driving safety may
be impaired. The causes for this include poten-
tially different tire casing structures and often
wide variations in tire ag e, which can result in a
limited service life. <
Correct wheels and tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount run-flat tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you.
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical offi cial size ratings could
actually have different dimensions, which could
lead to body contact an d thus to severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot guarantee their driving
safety. <
You can inquire about the right wheel/tire
combination at your BMW center.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS, DSC or
FTM.
To maintain good handling and vehicle
response, use only tires of a single brand and
tread configuration. Af ter a tire has been
damaged, mount the previous wheel and tire
combination again as soon as possible.
Wheels with Tire Pressure Monitor
TPM electronics
When mounting new tires or changing over
from summer to winter tires, or vice versa, only
use wheels with TPM electronics; otherwise,
the Tire Pressure Monito r may not be able to
detect a puncture, refer to page 102. Your
BMW center will be glad to advise you.

Coolant
Coolant consists of half water and half additive.
Not all commercially availa
ble additives are suit-
able for your BMW. Ask your BMW center about
suitable additives.
Only use suitable a dditives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is
important to follow the instructions on the
containers. <
Comply with the appropriate environ-
mental protection regulations when
disposing of coolant additives. <
Coolant temperature
If the coolant and therefore the engine over-
heats, a warning lamp lights up. A message
appears on the Control Display.
Checking coolant level
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns. <
1. Do not open the engine hood before the
engine has cooled down.
2. Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
pressure to escape, then continue turning
to open.
3. The level indicator 1 in the coolant filler
neck indicates the le vel of coolant. The
coolant level is correct when it is between
the arrows of the resp ective inscription on
the reservoir 2. 4.
If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5. Turn the cap until there is an audible click.
6. Have the reason for the coolant loss
eliminated as soon as possible.
