Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react to this below.

Red: stop immediately

Battery charge current

●

The battery is no longer being
charged. There is a malfunction
of the alternator drive belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

Engine oil pressure

●

An alarm sounds at the same
time. The engine oil pressure is
too low. Stop the vehicle immediately
and switch off the engine. It is not pos-
sible to continue driving. Please contact
the nearest BMW center.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

Flat Tire MonitorThe conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
In the event of tire pressure loss, the
rolling radius of the tire changes, and
thereby the rotational speed of the
wheel. This change is detected, and a
flat tire warning is issued to the driver.Functional requirementsTo ensure a reliable flat tire warning,
the system must be initialized with the
correct tire inflation pressures.
Initialize the system immediately
after you have corrected a tire
inflation pressure, or changed the tire
or wheel. The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
The system could issue a false warning
or function in a delayed manner in the
following situations:
>System was not initialized
>You are driving on a snow-covered or
slippery road surface
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>You are driving with snow chains.Initializing the system
The initialization is completed
while you are driving, and can be
interrupted at any time. Initialization is
automatically continued when you con-
tinue driving. When driving with snow
chains, do not initialize the system.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to, but no more than 8 seconds, until
the indicator lamp in the instrument
cluster lights up in yellow for several
seconds
3. Drive off. Initialization is completed
during the drive without any feed-
back issued.
When driving with snow chains,
do not initialize the system.<

To activate/deactivate the systemThe system is automatically activated in
ignition key position 2 and conse-
quently is on whenever the vehicle is
operated.
To deactivate the system: tap the but-
ton; the indicator lamp will light up yel-
low.
To activate the system: tap the button
again; the indicator lamp goes out.
Deactivate the system when snow
chains are mounted, since false warn-
ings and undetected losses in pressure
are possible under these kinds of con-
ditions.
Flat tire
The indicator lamp in the instru-
ment cluster lights up red. In
addition, an acoustic signal is
sounded.
1. Carefully reduce speed and come to
a stop. Avoid sudden braking and
steering maneuvers
2. Determine which wheel is damaged
If this cannot be determined, con-
tact your BMW center.<
3. Fix the flat tire using the M Mobility
system, refer to page 141
4. Press the button for approx.
4 seconds. The red indicator lamp
goes out.
After replacing the damaged tire, initial-
ize the system.
System malfunction
The indicator lamp in the instru-
ment cluster lights up yellow.
The Flat Tire Monitor is malfunc-
tioning or out of order. Please contact
your BMW center.

Cargo loading
Avoid overloading the vehicle so
that the permitted load on the tires
is not exceeded. Overloading can lead
to overheating and internal tire damage.
This can result in a sudden loss of tire
inflation pressure.<
Determining the maximum load1. Locate the following statement on
your vehicle's placard*:
The combined weight of occu-
pants and cargo should never
exceed XXX kg or YYY lbs., as this
could otherwise result in damage to the
vehicle or unstable driving conditions.<
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
4. The resulting figure equals the avail-
able amount of cargo and luggage
load capacity.
For example, if the YYY amount
equals 820 lbs. and there will be four
150 lbs. passengers in your vehicle,
the amount of available cargo and
luggage load capacity is 220 lbs.:
820 lbs. minus 600 lbs. = 220 lbs.
5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calculated
in Step 4
6. If your vehicle will be towing a trailer,
load from your trailer will be trans-
fered to your vehicle. Consult the
manual for transporting a trailer to
determine how this may reduce the
available cargo and luggage load
capacity of your vehicle.

Tire inflation pressureInformation for your safetyIt is not merely the tire's service life, but
also driving comfort and, above all else,
driving safety that depend on the condi-
tion of the tires and the maintenance of
the specified tire pressure.Checking tire pressuresOnly check the tire inflation pressures
of cold tires. This means after driving a
maximum of 1.25 miles/2 km or after
the vehicle has been parked for at least
2 hours. Warm tires have higher infla-
tion pressures.
Check tire inflation pressures reg-
ularly and correct them if neces-
sary: at least twice a month and before
beginning a longer trip. Otherwise,
incorrect tire pressures can cause driv-
ing instability or tire damage, ultimately
resulting in accidents. Do not drive on a
deflated, i.e. flat, tire. A flat tire greatly
impairs steering and braking response,
and can lead to complete loss of con-
trol over the vehicle.<
After correcting the tire inflation pres-
sure, reinitialize the Flat Tire Monitor,
refer to page 87.
Inflation pressures for original
tiresTire pressures for the standard tires of
your vehicle are shown on the driver's
door post, visible when the door is
open.
The inflation pressures apply to BMW-
approved tire sizes and recommended
tire brands. Your BMW center will be
glad to supply this information.Inflation pressures for other tire
sizesThe following tire pressure table shows
all tire pressures for the given tire sizes
at ambient temperature.

Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied 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, cornering,
hydroplaning, or peak traction charac-
teristics. highest, B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions 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 tem-
perature 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 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, under-inflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure. better winter driving properties than
summer tires.
Tire conditionWheel/tire damageInspect your tires frequently for signs of
damage, foreign objects and tread
wear, and check tread depth.
Due to low-profile tires, please
note that wheels, tires and sus-
pension parts are more susceptible to
road hazard and consequential dam-
ages.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect.
This type of problem can be caused by
contact with curbs, etc. This is also true
for irregularities in the vehicle's han-
dling characteristics, such as a pro-
nounced tendency to pull to the left or
right.
Should this occur, respond by immedi-
ately reducing your speed. Proceed
carefully to the nearest BMW center or
professional tire center, or have the
vehicle towed there. Tire damage, up to
and including blowouts, can endanger
the lives of both the vehicle occupants
and other road users.<

The correct wheels and tires
BMW recommends using only
wheels and tires that have been
tested and approved by BMW for the
particular vehicle model, as otherwise
body contact and serious accidents can
result despite the use of the same nom-
inal size, e.g. due to manufacturing tol-
erances. If non-approved wheels and
tires are used, BMW cannot evaluate
their suitability, and therefore cannot be
held liable for driving safety.<
To maintain good handling characteris-
tics, only use a full set of tires of the
same brand and tread configuration.
After a flat tire, have the previous wheel
and tire combination restored as soon
as possible.
Recommended tire sizes and
brandsFor each tire size, certain tire brands
have been tested, classified as road-
safe and approved by BMW. You can
find out about these from a professional
tire center, preferably your BMW cen-
ter. Observe any country-specific regu-
lations, e.g. on making a corresponding
entry in the vehicle documents.
The factory-approved radial belt tires
are matched to your vehicle and pro-
vide optimum safety and driving com-
fort when used properly.Special characteristics of winter
tiresBMW recommends the use of winter
tires for operation under winter road
conditions. While all-season tires with
M+S designation provide better winter
traction than summer tires, they gener-
ally do not achieve the full performance
of winter tires.Observing speed ratings
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW center
will be glad to assist you with the
required professional knowledge and
specialized equipment.<
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel. Do not
exceed the maximum tire inflation pres-
sures specified on the tire sidewall.
