Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but also
driving safety and driving comfort that largely
depend on the condition of the tires and the
maintenance of the specified tire pressure.
Check tire inflation pressures regularly
and correct them if necessary: at least
every two weeks and before every extended
journey. If you fail to observe this precaution
you may be driving on tires with incorrect tire
pressures, a condition that can not only com-
promise your vehicle's driving stability, but also
lead to tire damage and the risk of an accident.
Do not drive with deflated, i.e. flat tires, except
when using Run-Flat Tires. A flat tire will seri-
ously impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to loss of control over the vehicle.<
Checking pressure
Check the tire inflation pressures only when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. Warm tires
have higher inflation pressures.
Inflation pressure specifications
The specified inflation pressures for your stan-
dard tires are provided on the placard on the
B-pillar and are visible when the driver's door is
open.After the tire inflation pressure is cor-
rected, initialize the Flat Tire Monitor
*,
refer to page53, or reset the Tire Pressure
Monitor
*, refer to page54.<
The following tire inflation pressure tables show
the inflation pressures for the specified tire
sizes at ambient temperature.
The inflation pressures in the table apply
to BMW-approved tire sizes and recom-
mended tire brands. Your BMW center will be
glad to supply this information.<
To determine the correct tire inflation pressure
for your tires, refer to the following tables.
Tire size
The inflation pressures in the table apply to
BMW-approved tire sizes and recommended
tire brands. Your BMW center will be glad to

Jacking points
The jacking points are located at the positions
indicated in the illustration.
Vehicle battery
Maintenance
The battery is completely maintenance-free.
This means that the original electrolyte will nor-
mally last for the service life of the battery under
moderate climatic conditions. Your BMW cen-
ter will be happy to advise you if you have any
questions concerning the battery.
Indicator lamp
The indicator lamp lights up:
The battery is no longer being charged.
The alternator drive belt is defective or
there is a malfunction in the charging circuit of
the alternator. Have the system checked as
soon as possible.
If the drive belt is defective, pull over and
switch off the engine immediately to pre-
vent overheating and serious engine damage.
If the onboard supply voltage drops to a very
low level, increased steering effort may also be
necessary.<
Charging the battery
Charge the battery in the vehicle only when the
engine has been switched off. Connections,
refer to Jump-starting on page104.
Battery disposal
After changing a battery, have the used
battery disposed of by your BMW center or bring it to a recycling point. Maintain the bat-
tery in an upright position for transport and stor-
age. Secure the battery against tilting when
transporting.<
Power loss
After a temporary power loss, the functioning of
some equipment may be limited and require ini-
tialization. Individual settings are also lost and
must be reset:
>Seat memory
The positions must be stored again, refer to
page32.
>Clock must be reset, refer to page49.
Fuses
Do not attempt to repair a burned fuse or
replace it with a fuse having a different
color or amperage rating. To do this could
cause a fire in the vehicle as a result of circuit
overload.<
You will find the fuses and information on their
respective allocation behind the glove compart-
ment.
1.Open the glove compartment.
2.Press the lock on the left, arrow1.
3.Press the lock on the right, arrow2.
4.Swing the glove compartment down.
Spare fuses and plastic tweezers for grasping
the fuses are found in the onboard tool kit; refer
to page98.
