Changing a wheel Battery 
The spare wheel has a size 
235/65 R 17 tire. If you have 
mounted tires on your vehicle with a 
different size, have wheels and tires of 
the same size and specification rein-
stalled as soon as possible.
When the spare wheel is mounted, the 
maximum speed rating is 130 mph 
(210 km/h).<
Protect valve stems and valves from dirt 
using screw-on valve stem caps. Dirt in 
the valve stems frequently leads to slow 
leaks.
Battery posts, terminals and 
related accessories contain lead 
and lead compounds. Wash hands after 
handling.<
MaintenanceThe battery is maintenance-free, that is, 
the original electrolyte will normally last 
for the service life of the battery under 
moderate climatic conditions. 
For all questions that regard the 
battery, please consult your 
BMW Sports Activity Vehicle center. 
Since the battery is maintenance-free, 
the following is for your information 
only.< 
Do not disconnect the battery 
when the engine is running. If 
you do so, the ensuing voltage surge 
will damage the vehicle's onboard elec-
tronics.<
Charging the battery Charge the battery in the vehicle only 
when the engine is not running. Use the 
connections provided in the engine 
compartment (for correct connections, 
refer to "Jump-starting" on page 164). 
Return used batteries to a recy-
cling point or your BMW Sports 
Activity Vehicle center. Maintain the 
battery in an upright position for trans-
port and storage. Secure the battery 
against tilting during transport.<
