Wheels and tires
Tire inflation pressure
Safety information
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres‐
sure.
Checking the pressure
Only check the tire inflation pressure 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. When the tires
are warm, the tire inflation pressure is higher.
Check the tire inflation pressure regularly
Check the tire inflation pressure regularly
and correct it if necessary, even in the compact
wheel*: usually twice monthly or before embark‐
ing on a long trip. If you fail to observe this pre‐
caution, you may be driving on tires with incor‐
rect 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 acci‐
dent.
Do not drive with depressurized or flat tires, ex‐
cept for run-flat tires. A flat tire will seriously im‐
pair your vehicle's handling and braking re‐
sponse. Attempts to drive on a flat tire can lead
to a loss of control over the vehicle.◀
After adjusting the tire inflation pressure, reset
the Tire Pressure Monitor, refer to page 90, or
reinitialize the Flat Tire Monitor, refer to
page 88.
Pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire sizes
approved and tire brands recommended by BMW; a list of these is available from your serv‐
ice center.
For
correct identification of the right tire inflation
pressures, observe the following:
▷ Tire sizes of your vehicle.
▷ Maximum allowable driving speed.
Tire inflation pressures for driving up to
100 mph or 160 km/h
For
normal driving up to 100 mph/160 km/h, ad‐
just pressures to the respective tire inflation
pressures listed on the following pages in the
column for traveling speeds up to 100 mph/
160 km/h to achieve optimum driving comfort.
These tire inflation pressures can also be found
on the driver's side door pillar when the driver's
door is open. Do not exceed the maximum permissible
speed
The maximum permissible speed for these tire
pressures is 100 mph/160 km/h Do not exceed
this speed; otherwise, tire damage and acci‐
dents could occur.◀
Tire inflation pressures for driving
above 100 mph or 160 km/h
Adjust the tire inflation pressures
To drive at maximum speeds in excess of
100 mph/160 km/h, adjust pressures to the re‐
spective
tire inflation pressures listed on the fol‐
lowing pages in the column for traveling speeds
including those exceeding 100 mph or 160 km/ Seite 252

Wheels and tires
The defective wheel cannot be stored under
the floor panel flap due to its size.
3. Check and correct the tire inflation pressure
at the earliest opportunity.
4. Initialize the Flat Tire Monitor, refer to
page 88,
or reset the Tire Pressure Monitor,
refer to page 90.
5. Replace the damaged tire as soon as possi‐
ble and have the new wheel/tire balanced.
Driving with compact wheel Do not exceed a speed of 50 mph/80 km/
h.
Drive
conservatively and do not exceed a speed
of 50 mph/80 km/h. Otherwise, changes in the
driving characteristics could result, for example
reduced track stability on braking, extended
braking distance, and altered self-steering char‐
acteristics in the limit range. In conjunction with
winter tires, these characteristics are more pro‐
nounced.◀
Only mount one compact wheel
Only one compact wheel may be
mounted. Restore the wheels and tires to their
original size as quickly as possible. Failure to do
so is a safety risk.◀
Vehicle battery
Maintenance
The battery is maintenance-free, i.e., the elec‐
trolyte will last for the life of the battery.
Your service center will be glad to advise you on
questions regarding the battery.
Battery replacement
Use approved vehicle batteries
Only use vehicle batteries that have been
approved for your vehicle by the manufacturer;
otherwise, the vehicle could be damaged and
systems or functions may not be fully availa‐
ble.◀ After a battery replacement, have the battery
registered
on the vehicle by your service center
to ensure that all comfort functions are fully
available.
Charging the battery
In the vehicle, only charge the battery via the
terminals in the engine compartment, refer to
page 281, with the engine switched off.
Power failure
After a temporary power loss, some equipment
needs to be reinitialized.
Individual settings need to be reprogrammed:
▷ Seat and mirror memory: store the positions
again, refer to page 53.
▷ Time: update, refer to page 78.
▷ Date: update, refer to page 79.
▷ Radio station: save again, refer to page 174.
▷ Navigation system: wait for the navigation
system to be operational.
▷ Glass sunroof/panoramic glass sunroof: it
may
only be possible to raise the roof. Have
the system initialized by the service center.
▷ Digital compass: recalibrate, refer to
page 129.
▷ Active steering: the system automatically in‐
itializes for a short time as you drive. During
this
time, the system is deactivated, refer to
page 101.
▷ xDrive: the system automatically initializes
as you drive. During this time, indicator
lamps
light up. If the lamps do not disappear
during the current trip, have the system
checked.
Disposing of old batteries Have old batteries disposed of by your
service center or bring them to a recy‐
cling center.
Maintain the battery in an upright position for
transport and storage. Secure the battery so
that it does not tip over during transport. Seite 278
