2012 BMW 650I tires

Things to remember when driving
Breaking-in period
General information
Moving parts need to be broken in to adjust to
each other.
The following instructions will help achieve a
long vehicle life and good economy.
Engine and differential
Always obey the official speed limit.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:
▷
For gasoline engine, 4500 rpm and
100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode for the initial
miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture,
tires do not achieve their full trac‐
tion potential until after an initial breaking-in pe‐
riod.
Drive conservatively for the first 200 miles/
300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and discs. Drive moderately during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx. 300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The

same breaking in procedures should be ob‐
served if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Closing the trunk lid
Drive with the trunk lid closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking or
evasive maneuvers, passengers or other road
users may be injured or the vehicle may be dam‐
aged. In addition, exhaust fumes may enter the
passenger compartment.◀
If driving with the tailgate open cannot be
avoided:
▷ If the convertible top is closed, close all win‐
dows.
▷ Greatly increase the blower speed.
▷ Drive moderately.
Hot exhaust system Hot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. When driv‐
ing,

standing at idle and while parking, take care
to avoid possible contact between the hot ex‐
haust system and any highly flammable materi‐
als such as hay, leaves, grass, etc. Such contact
could lead to a fire, and with it the risk of serious
personal injury as well as property damage.
Do not touch hot exhaust pipes; otherwise, there
is the danger of getting burned.◀ Seite 138

Things to remember when driving

Climate control windshield*
The marked area is not covered with heat re‐
flective coating.
Use this area for garage door openers, devices
for electronic toll collection, etc.
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It
is advised that you do not use mobile commu‐
nication devices, e.g., mobile phones, inside the
vehicle without connecting them directly to the
external antenna. Otherwise, the vehicle elec‐
tronics and mobile communication devices can
interfere with each other. In addition, there is no
assurance that the radiation generated during
transmission will be discharged from the vehicle
interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀ Driving through water
Drive though calm water only if it is not deeper
than 9.8 inches/25 cm and at this height, no
faster

than walking speed, up to 6 mph/10 km/h.
Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the elec‐
trical systems and the transmission may be
damaged.◀
Braking safely
Your vehicle is equipped with ABS as a standard
feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsiveness.
You can still avoid any obstacles with a minimum
of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
Objects in the area around the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved for
the vehicle and can be properly fixed in place.
Ensure that the floor mats are securely fastened
again after they were removed for cleaning, for
example.◀
Driving in wet conditions
When roads are wet or there is heavy rain, briefly
exert gentle pressure on the brake pedal every
few miles.
Ensure that this action does not endanger other
road users. Seite 139

The heat generated in this process helps dry the
brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive
long or steep downhill gradients in the gear
in which the least braking is required. Otherwise,
the brake system may overheat, resulting in a
reduction in the brake system efficiency.
Manual transmission:
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
necessary.
Automatic transmission*:
You can increase the engine's braking effect by
shifting down in the manual mode of the auto‐
matic transmission, refer to page 72.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking. In
addition, steering and brake assist is unavailable
with the engine stopped.◀
Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are furthered by:
▷ Low mileage.
▷ Extended periods when the vehicle is not
used at all.
▷ Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected. Condensation under the parked vehicle
When
using the automatic climate control, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.
Loading
Overloading the vehicle
To avoid exceeding the approved carrying
capacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden loss
of tire inflation pressure.◀
No fluids in the trunk
Make sure that fluids do not leak into the
trunk; otherwise, the vehicle may be damaged.◀
Determining the load limit 1.
Locate the following statement on your ve‐
hicle’s placard*:
▷The combined weight of occupants and
cargo should never exceed XXX kg or
YYY lbs. Otherwise, damage to the ve‐
hicle

and unstable driving situations may
result.
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver
and

passengers from XXX kilograms or YYY
pounds. Seite 140

Tire inflation pressure
Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:
▷
The service life of the tires.
▷ Road safety.
▷ Driving comfort.
Checking the pressure
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been
parked for at least 2 hours. When the tires
are warm, the tire inflation pressure is higher.
Check the tire inflation pressure regularly
Regularly check the tire inflation pressure
and correct it as needed: at least twice a month
and before a long trip. If you fail to observe this
precaution, you may be driving on tires with in‐
correct tire pressures, a condition that may not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.◀
After correcting the tire inflation pressure, rein‐
itialize the Flat Tire Monitor.
After correcting the tire inflation pressure, rein‐
itialize the Tire Pressure Monitor.
Pressure specifications
The tire inflation pressure table, refer to
page 230, contains all pressure specifications
for the specified tire sizes at the ambient tem‐
perature. Pressure specifications apply to ap‐
proved tire sizes and recommended tire brands.
This information can be obtained from your
service center.
To identify the correct tire inflation pressure,
please note the following:
▷ Tire sizes of your vehicle.
▷ Vehicle load. ▷
Maximum allowable driving speed.
Tire inflation pressures up to 100 mph/
160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum

driving comfort, note the pressure val‐
ues in the tire inflation pressure table, refer to
page 230, and adjust as necessary. These pressure values can also be found on the
tire inflation pressure label on the driver's door
pillar.
Maximum permissible speed
Do not exceed 100 mph/160 km/h; other‐
wise, tire damage and accidents may result.

Regardless of wear, replace tires at least every
6 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: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Federal
Safety Requirements in addition to these
grades.
Treadwear
The treadwear 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, 1 g, 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, however,
and may depart significantly from the norm due
to variations in driving habits, service practices
and differences in road characteristics and cli‐
mate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfa‐
ces 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, cornering, hydro‐
planing, or peak traction characteristics.

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. Sus‐
tained 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 Vehicle Safety
Standard No. 109. Grades Band A represent
higher levels of performance on the laboratory
test wheel than the minimum required by law.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or in
combination, can cause heat buildup and pos‐
sible tire failure.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 234, are labeled with
a circular symbol containing the letters RSC
marked on the sidewall.
M+S
Winter and all-season tires with better cold
weather performance than summer tires.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
There is an increased danger of hydroplaning if
the tread depth is less than 0.12 in/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm. Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the tire's
circumference and have the legally required
minimum height of 0.063 in/1.6 mm.
They

are marked on the side of the tire with TWI,
Tread Wear Indicator.
Tire damage
General information
Inspect your tires often for damage, foreign ob‐
jects lodged in the tread, and tread wear.
Notes
Indications of tire damage or other vehicle de‐
fects:
▷ Unusual vibrations during driving.
▷ Unusual handling such as a strong tendency
to pull to the left or right.
In case of tire damage
If there are indications of tire damage, re‐
duce your speed immediately and have the
wheels

and tires checked right away; otherwise,
there is the increased risk of an accident.
Drive carefully to the next service center or tire
shop.
If necessary, have the vehicle towed.◀
Repair of tire damage
For safety reasons, the manufacturer of
your vehicle recommends that you do not have
damaged tires repaired; they should be re‐ Seite 232
