wheel BMW 428I CONVERTIBLE 2016 Repair Manual

StorageStore 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 pres‐
sure indicated on the side wall of the tire.
Run-flat tires Label
RSC label on the tire sidewall.
The wheels consist of tires that are self-sup‐
porting, to a limited degree, and possibly spe‐
cial rims.
The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a tire inflation pressure loss.
Follow the instructions for continued driving
with a flat tire.
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
Your service center will be glad to advise you.
Mobility System
The concept With the Mobility System, minor tire damagecan be sealed quickly to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the inside.
The compressor can be used to check the tire inflation pressure.
Hints▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 in/4 mm or more.▷Contact the nearest service center if the
tire cannot be made drivable.▷If possible, do not remove foreign bodies
that have penetrated the tire.▷Pull the speed limit sticker off the sealant
container and apply it to the steering
wheel.▷The use of a sealant can damage the TPM
wheel electronics. In this case, have the
electronics checked at the next opportu‐
nity and have them replaced if needed.
Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Storage The Mobility System is located under the
cargo floor panel.

Switch off the compressor after 10 mi‐
nutes
Do not allow the compressor to run longer than
10 minutes; otherwise, the device will overheat
and may be damaged.◀
Let the compressor run for approx. 3 to 8 mi‐
nutes to fill the tire with sealant and achieve a
tire inflation pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the
tire inflation pressure may sporadically reach
approx. 5 bar. Do not reel off the compressor at
this point.
If a tire inflation pressure of 2 bar is not
reached:
1.Switch off the compressor.2.Unscrew the filling hose from the wheel.3.Drive 33 ft/10 m forward and back to dis‐
tribute the sealant in the tire.4.Inflate the tire again using the compressor.
If a tire inflation pressure of 2 bar cannot be
reached, contact your service center.

3.Wrap the empty sealant container and con‐
nection hose in suitable material to avoid
dirtying the cargo area.4.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Do not exceed a speed of 50 mph/80 km/h.
If possible, do not drive at speeds less than
12 mph/20 km/h.
To correct the tire inflation pressure
1.Stop at a suitable location.2.Screw the connection hose onto the tire
valve stem.3.Attach the connection hose directly to the
compressor.4.Insert the connector into a power socket
inside the vehicle.5.Correct the tire inflation pressure to
2.5 bar.▷Increase pressure: with the ignition
turned on or the engine running, reel
on the compressor.▷To reduce the pressure: press the but‐
ton on the compressor.

necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Car washes General information
Regularly remove foreign objects such as
leaves in the area below the windshield when
the hood is raised.
Wash your vehicle frequently, particularly in
winter. Intense soiling and road salt can dam‐
age the vehicle.
Hints Steam jets or high-pressure washers
When using steam jets or high-pressure
washers, hold them a sufficient distance away
and use a maximum temperature of
140 ℉/60 ℃.
Holding them too close or using excessively
high pressures or temperatures can cause
damage or preliminary damage that may then lead to long-term damage.
Follow the user's manual for the high-pressure
washer.◀
Cleaning sensors/cameras/hardtop with
high-pressure washers
When using high-pressure washers, do not
spray the seals of the lowerable hardtop, sen‐
sors and cameras external to the vehicle, e.g.,Park Distance Control, for extended periods of
time and only from a distance of at least
12 in/30 cm.◀
Automatic car washes
Hints Do not use high pressure washing sys‐
tems
With washing systems operating at high pres‐
sures and nozzle positions close to the win‐
dows, drops of water can penetrate.◀▷Give preference to cloth car washes or
those that use soft brushes in order to
avoid paint damage.▷Make sure that the wheels and tires are not
damaged by the transport mechanisms.▷Fold in the exterior mirrors; otherwise, they
may be damaged, depending on the width
of the vehicle.▷Deactivate the rain sensor, refer to
page 70, to avoid unintentional wiper acti‐
vation.▷In some cases, an unintentional alarm can
be triggered by the interior motion sensor
of the alarm system. Follow the instruc‐
tions on avoiding an unintentional alarm,

Otherwise, particles of dust and road grime
chafe in pores and folds, and lead to increased
wear and premature degradation of the leather
surface.
To guard against discoloration, such as from
clothing, provide leather care roughly every
two months.
Clean light-colored leather more frequently be‐
cause soiling on such surfaces is substantially
more visible.
Use leather care products; otherwise, dirt and
grease will gradually break down the protective
layer of the leather surface.
Suitable care products are available from the
service center.
Upholstery material care Vacuum regularly with a vacuum cleaner.
If upholstery is very dirty, e.g., with beverage
stains, use a soft sponge or microfiber cloth
with a suitable interior cleaner.
Clean the upholstery down to the seams using
large sweeping motions. Avoid rubbing the
material vigorously.
Damage from Velcro® fasteners
Open Velcro® fasteners on pants or
other articles of clothing can damage the seat
covers. Ensure that any Velcro® fasteners are
closed.◀
Caring for special components
Light-alloy wheels When cleaning the vehicle, use only neutral
wheel cleaners having a pH value from 5 to 9.
Do not use abrasive cleaning agents or steam
jets above 140 ℉/60 ℃. Follow the manufac‐
turer's instructions.
Aggressive, acidic or alkaline cleaning agents
can destroy the protective layer of adjacent
components, such as the brake disk.Chrome surfaces
Carefully clean components such as the radia‐
tor grille or door handles with an ample supply
of water, possibly with shampoo added, partic‐
ularly when they have been exposed to road
salt.
Rubber components
Aside from water, treat only with rubber
cleansers.
When cleaning rubber seals, do not use any
silicon-containing car care products in order to
avoid damage or noises.

Clean with a microfiber cloth.
Dampen cloth lightly with water.
Do not soak the roofliner.
No cleansers that contain alcohol or sol‐
vents
Do not use cleansers that contain alcohol or
solvents, such as lacquer thinners, heavy-duty
grease removers, fuel, or such; this could lead
to surface damage.◀
