2004 BMW 760Li four wheel drive

Adjustments
52
Illuminated vanity mirror in the rear
1.Press button 1. The vanity mirror folds
down
2.Pull the mirror slightly downwards
before you swivel it
3.Press the vanity mirror back up before
folding it back in.
Steering wheel adjustment
The steering wheel can be adjusted in any
of four directions by pressing the appropri-
ate end of the button.
Do not adjust the steering wheel while
the vehicle is moving. There is a risk
of accident from unexpected movement.<
Storing steering wheel positions, refer to
Seat, mirror and steering wheel memory on
page 53.
Automatic steering wheel
adjustment
The steering wheel automatically moves as
high up and far forward as possible to ease
driver entry and exit before then returning
to the standard position or stored memory
setting. This automatic feature is governed by the
driver's door and the ignition switch.
Steering wheel heater*
The steering wheel heater operates when
the ignition is on.
Press the button to activate or deactivate
this system.
The indicator lamp within the button lights
up when the steering wheel heater is in
operation.
Programming button function
You can assign specific individual
functions to the programmable but-
ton. This feature then provides you
with quick access to this function, allowing
you to control it without undue distraction
from road and traffic conditions.
1.Select "Settings"
2.Confirm
3.Select " button". Continue to press
the controller until the desired function
appears:
>"Recirc. air"
In this mode the supply of outside air
remains blocked, refer to AUC Auto-

Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires as
you drive. The system provides an alert
whenever the inflation pressure of one tire
drops significantly in relation to the pres-
sure of another tire.
The check of the tire inflation pressure is
based on monitoring the relative speeds of
the wheels. A flat tire is detected and
reported on the basis of a deviation in cer-
tain speed ratios.
Functional requirements
So that the Flat Tire Monitor can learn the
correct inflation pressure, please perform
the following:
1.Check the inflation pressures in all tires
2.Compare with the inflation pressure
table on page 189 and correct if neces-
sary
3.Initialize the system.
Limits of the system
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused
by outside factors and does not detect a
natural, even pressure drop in all four
tires.<
In the following situations, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
>When you are driving on snow-covered
or slippery road surfaces
>In the case of performance-oriented
driving: slip on the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are driv-
ing with snow chains fitted.
Initializing the system
Perform the initialization immediately
after correcting the inflation pressure,
changing a tire or changing a wheel or all
wheels. A drive is necessary for this pur-
pose.<
1.Start the engine, but do not drive off
2.Select "FTM" from the "Settings" menu
and confirm. The initialization menu
appears
3.Select "SET" and confirm
4.Drive off.
Status: "FTM is being initialized" is dis-
played.
It takes at least 10 minutes before the Flat
Tire Monitor can detect and report a flat
tire.
When driving with snow chains, do
not initialize the system.<
Select and confirm to exit from the
menu.

Run-flat tires*
You will recognize run-flat tires by a circu-
lar symbol containing the letters RSC on
the side of the tire. They consist of self-
contained tires and special rims. The tire
reinforcement ensures that the tire retains
some residual safety in the event of pres-
sure drop and driving remains possible
to a restricted degree. The vehicle is
equipped with a Flat Tire Monitor which
indicates punctures.
The reinforcement on the flanks of the
tires means that it is usually not pos-
sible to detect an air loss from outside.<
Flat tire
If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
You can find more detailed information on
the Flat Tire Monitor on page 95.
Reduce vehicle speed carefully to under
50 mph/80 km/h, avoiding hard brake
applications and steering maneuvers.
If the defective wheel is not recognizable
as such immediately, check the inflation
pressure in all four tires.
For reasons of safety, do not arrange
for run-flat tires to be repaired. Your
BMW center has the information needed
for working with these tires and is equipped
with the necessary special tools.<
Continuing driving with a damaged
tire
Driving on run-flat tires can continue
depending on the vehicle load and the
severity of the tire damage, at a maximum
speed of 50 mph/80 km/h. You can deter-
mine the possible mileage for continued
driving on the basis of the following general
indications:
>Tire inflation pressure 0 psi/kPa:
With empty vehicle approx. 90 miles/
150 km
With full payload approx. 30 miles/
50 km
>Tire inflation pressure 7 psi/50 kPa to
15 psi/100 kPa:
Approx. 300 miles/500 km
>Tire inflation pressure greater than
15 psi/100 kPa:
Approx. 600 miles/1,000 km.
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the case
of air loss, you can expect changes in vehi-
cle handling such as reduced lane stability,
longer braking distances, and changes in
self-steering properties.<
Battery
Battery care
The battery is 100 % maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate.
For all questions that regard the bat-
tery, please consult your BMW cen-
ter.<
Charging the battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump-starting on page 208.
