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
suitable for winter conditions. For the sake of
safety, new tires should be installed.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has been driven down to the wear indicators, a
tread depth of 0.063 in/1.6 mm has been
reached.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazards and consequential dam-
ages.
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. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.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 shop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If necessary,
have the vehicle towed there. Otherwise, tire
damage can be extremely dangerous to vehicle
occupants and other road users.<
Run-flat tires*
You will recognize run-flat tires by the circular
symbol containing the letters RSC on the side
of the tire.
Run-flat tires consist of partially self-contained
tires and special rims. The sidewall reinforce-
ment ensures that the tire retains some residual
safety in the event of pressure drop and driving
remains possible to a restricted degree.
To continue driving with a damaged tire:
>With Flat Tire Monitor, refer to Indication of
a flat tire, page96
>With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure,
page98
New wheels and tires
Have new wheels and tires installed only
by your BMW center or tire shop that
works according to BMW repair procedures
with correspondingly trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards. Make sure that the new wheels are bal-
anced.<

Wheels and tires
228
Retreaded tires
BMW does not recommend that you use
retreaded tires, as driving safety may be
impaired. The causes for this include the possi-
bly different tire casing structures and the often
wide variations in their age, which can result in a
limited service life.<
The right wheels and tires
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 official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact, and with it the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct wheel/tire combination also affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. Following
tire damage, have the original wheel and tire
combination remounted on the vehicle as soon
as possible.
Wheels with electronics for
TPM Tire Pressure Monitor
When mounting new tires or converting from
summer to winter tires or vice versa, only use
wheels with TPM electronics, otherwise the
Tire Pressure Monitor cannot detect a flat tire,
refer to page97. Your BMW center will be
happy to advise you on this subject.
Recommended tire brands
Certain tire makes are recommended by BMW
depending on the tire size. You can recognize
these from the clearly visible BMW marking on
the tire sidewall.
When used properly, these tires comply with
the most demanding standards for safety and
vehicle response.
Run-flat tires
When mounting new tires, or changing from
summer to winter tires or vice versa, use run-flat
tires for your own safety. In addition, no spare
tire is available in case of a flat tire. Your BMW
center will be glad to advise you.
For safety reasons, BMW recommends
that you do not have damaged run-flat
tires repaired; they should be replaced. Other-
wise it is not possible to rule out occurrences of
consequential damage.<
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Paying attention to speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
t i re d a m a g e m a y o c cu r , w h ic h c a n re s u l t i n a c c i-
dents.<

Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels. Do not exceed the maximum tire
inflation pressure indicated on the side wall of
the tire.
Rotating wheels between axles
BMW does not recommend moving the front
wheels to the rear or vice versa, as otherwise
the handling characteristics may be impaired.
With tires of different makes and types
* such a
change is not permissible.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
Use is only permissible in pairs on the rear
wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
After mounting snow chains, do not ini-
tialize the Flat Tire Monitor, otherwise
incorrect displays can occur.
When driving with snow chains, it may be prac-
tical to briefly activate DTC, refer to page92.<

Changing wheels
Safety precautions in the event of a flat
tire or wheel change: park the vehicle as
far as possible from passing traffic and on solid
ground. Switch on the hazard warning flashers.
Have all vehicle occupants get out of the vehicle
and ensure that they remain outside the imme-
diate area in a safe place, such as behind a
guardrail.
If a warning triangle
* or portable hazard warning
lamp
* is r e q u ir e d, s et i t up o n t h e ro a d s i d e a t a n
appropriate distance from the rear of the vehi-
cle. Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm surface
which is not slippery. The vehicle or the jack
could slip to the side if you attempt to raise the
vehicle on a soft or slippery surface such as
snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar object as a
support base for the jack, as this would prevent
it from extending to its full support height and
reduce its load-carrying capacity.
To avoid serious or fatal injury: never lie under
the vehicle, and never start the engine while it is
supported by the jack.<

Compact wheel*
1.Unscrew the wing nut 1.
2.Remove the washer 2 laterally.
3.Take out the tool mounts 3.
4.Remove the compact wheel.
Preparing wheel change
1.Observe the safety precautions above.
2.Prevent the vehicle from rolling:
Place the chock behind the front wheel on
the other side of the vehicle, or on inclines,
in front of this wheel. On steeply inclined
roads, always secure the vehicle against
rolling.
3.Loosen the lug bolts a half turn.
Jacking up vehicle
1.Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base rests on the ground
perpendicularly beneath the jacking point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.<
2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to illustration detail.3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.
3.Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the
lug bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. Otherwise, incorrectly tight-
ened lug bolts are a hidden safety risk. The
tightening torque is 88.5 lb ft/120 Nm.<
2.When stowing the wheel and tools in the
vehicle, execute these steps in the reverse
order.
3.Check and correct the tire inflation pressure
at the earliest opportunity.

Protect valve stems with valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to
page95, or reset the Tire Pressure Monitor,
refer to page97.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics are more
pronounced.
Only one compact wheel may be
mounted. Restore the wheels and tires to
their original size as quickly as possible. Failure
to do so is a safety risk.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW center will be glad to advise in
all matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. Connections, refer to
Jump starting on page248.
Disposal
Have old batteries disposed of by your
BMW center or hand them in to a recy-
cling center. Maintain the battery in an upright
position for transport and storage. Always
restrain the battery to prevent it from tipping
over during transport.<
Power failure
After a temporary power supply interruption,
some settings are lost. Take the following
steps:
>Seat, mirror and steering wheel memory
Store the positions again, refer to page48.
>Time and date
Reset, refer to text starting on page86.
>Radio
Store stations again, refer to page174.
>Navigation system
Wait until the system starts, refer to
page142.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, as
this could lead to a circuit overload, ultimately
resulting in a fire in the vehicle.<
Sedan
Spare fuses, plastic tweezers and fuse alloca-
tion diagram are located in the compartment for
the onboard tool kit, refer to page237.
Sports Wagon
Spare fuses and a pair of plastic tweezers are
contained in the onboard tool kit, refer to
