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. Stop vehicle immediately
and switch off engine. Check the
engine oil level and top up as required.
If the oil level is correct: please contact
the nearest BMW center.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

<

Flat Tire Monitor

●

In addition, an acoustic signal is
sounded: there is a flat tire.
Reduce speed and carefully come to a
stop. Avoid sudden braking and steer-
ing maneuvers.
For additional information: refer to
page 87
Brake warning lamp

●

If the lamp comes on when the
parking brake is not engaged:
check the brake fluid level. Before driv-
ing further, be sure to comply with the
instructions on pages 114 and 129.

Passenger-side exterior mirror tilt
functionAutomatic curb monitor*
1. Move mirror selector switch 1 to the
driver's mirror position
2. When shifting into Reverse, or plac-
ing the selector lever in position R,
the passenger-side mirror tilts down-
ward. This brings the lower area
adjacent to the vehicle – curbs, etc. –
into the driver's field of vision while
parking.
How far the passenger mirror tilts
can be set individually for each
ignition key.<
You can deactivate this automatic fea-
ture by setting the mirror selection
switch to the passenger side position.
Seat heating*The seat cushion and backrest can be
heated with the ignition key in
position 2.
You can call up different heating modes
by repeatedly pressing the buttons.
You can also switch the higher heating
modes off directly:
Press the button and hold it slightly
longer.

Tips for pleasant drivingUse the automatic mode – switch on
with AUTO button 6. Select the desired
interior temperature.
Detailed setting options are described
for you in the following sections.
You can make the settings of your
vehicle in such a manner that,
when you unlock the vehicle with the
remote control of your personal key,
your own personalized setting for the
automatic climate control is initiated. supply
The AUTO program adjusts the
air distribution and the air sup-
ply for you and in addition adapts the
temperature to external influences –
summer, winter – to meet preferences
you can specify.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. Air flows onto
the windows , toward the upper
body , and into the footwell . You
can reactivate the automatic air supply
by pressing the AUTO button.Temperature
The interior temperature that
appears in the display panel is a
general figure intended for refer-
ence purposes. We recommend
727/+226 as a comfortable setting,
even if the air conditioning is on. When
you start the vehicle, the system
ensures that the selected temperature
is reached as quickly as possible. It
then maintains this temperature,
regardless of the season.
To select the units of measure 6/7
of the display, refer to page 83.
Air supply/Blower
By pressing the upper or lower
button, you can vary the air sup-
ply. This deactivates the auto-
matic air supply – the AUTO display dis-
appears from the panel. Nevertheless,
the automatic air distribution remains
unchanged. You can reactivate the
automatic air supply by pressing the
AUTO button.
When the lowest blower speed is set
and you press the lower button, all of
the displays are canceled: the blower,
heating and air conditioner are
switched off, and the air supply is
stopped. You can reactivate the system
by pressing any button for the auto-
matic climate control.To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and the side windows.
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the
temperature setting – rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Air conditioning helps
prevent the windows from fogging up.
Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<

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 XXX amount
equals 1,400 lbs. and there will be
five 150 lbs. passengers in your vehi-
cle, the amount of available cargo
and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 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.

119
Do not drive on a deflated – flat –
tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle.
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.
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
immediately reducing your speed. Pro-
ceed carefully to the nearest BMW cen-
ter or professional tire center, or have
the vehicle towed in to have it, its
wheels or its tires inspected.
Tire damage, up to and including blow-
outs, can endanger the lives of both the
vehicle occupants and other road
users.<
Tire replacementTo maintain good handling characteris-
tics, only use a full set of tires of the
same brand and tread configuration.
Comply with the specified tire inflation
pressures, and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.DOT quality grades>Treadwear
>Traction AA A B C
>Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades. rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half – 1
1/2 – times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.TractionThe 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 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.
