Wheels and tires
Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance 
of the specified tire pressure are crucial not only 
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check 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 tires are 
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly 
and correct it as needed, even on the 
compact tire
*: at least twice a month and before 
starting long trips. Otherwise driving instability 
or tire damage, and therefore accidents, can 
result from incorrect tire inflation pressures. 
Do not drive with depressurized, i.e. flat tires, 
except run-flat tires. A flat tire will seriously 
impair your vehicle's handling and braking 
response. Attempts to drive on a flat tire can 
lead to a loss of control over the vehicle.<
After correcting the tire inflation pressure, 
reinitialize the Flat Tire Monitor, refer to 
page90, or reset the Tire Pressure Monitor, 
refer to page92.<
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 and tire brands respectively 
approved and recommended by BMW; a list of 
these is available from your BMW center.
tion pressure for your tires, observe the follow-
ing:
>Tire sizes of your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for speeds 
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h, 
adjust pressures to the respective tire inflation 
pressures listed on the following pages in the 
column Traveling speeds up to max. 100 mph/
160 km/h to achieve optimum driving comfort.
These pressure specifications can be found on 
the door post when you open the driver's door.
The permissible top speed for these tire 
inflation pressures is 100 mph/160 km/h. 
Do not exceed this speed, otherwise tire dam-
age and accidents may result.<
Tire inflation pressures for speeds 
above 100 mph/160 km/h
In order to drive at maximum speeds in 
excess of 100 mph/160 km/h, please 
observe, and, if necessary, adjust tire pressures 
for speeds exceeding 100 mph/160 km/h from 
the relevant table on the following pages. Oth-
erwise tire damage and accidents could 
occur.<
Observe all national and local maximum speed 
limits, otherwise violations of the law could 
occur.

face of the jack base rests on the ground 
perpendicularly beneath the jacking point.
The vehicle jack is designed for 
changing wheels only. Do not attempt 
to raise another vehicle model with it or to 
raise any load of any kind. To do so could 
cause accidents and personal injury.<
2.Guide the jack head into the rectangular 
recess of the jacking point when cranking 
up, refer to illustration detail.
3.Jack the vehicle up until the wheel you are 
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the 
wheel.
2.Remove accumulations of mud or dirt from 
the mounting surfaces of the wheel and 
hub. Also clean the lug bolts.
3.Position the new wheel or compact wheel. 
Secure the wheel by screwing at least two 
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug 
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all 
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from 
beneath the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the 
lug bolts checked with a calibrated 
torque wrench as soon as possible to 
ensure that they are tightened to the specified torque. The tightening torque is 
88.5 lb ft/120 Nm.<
2.When stowing the wheel and tools in the 
vehicle, execute these steps in the reverse 
order.
3.Check and correct the tire inflation pressure 
at the earliest opportunity.
Protect valve stems and valve stem 
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source 
of gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to 
page90, or reset the Tire Pressure Monitor, 
refer to page92.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of 
50 mph/80 km/h.
The driving characteristics change, for example 
reduced track stability on braking, extended 
braking distance, and altered self-steering 
characteristics in the limit range. In conjunction 
with winter tires, these characteristics are more 
pronounced.
Only one compact wheel may be 
mounted. You should re-equip with 
wheels and tires of the original size as quickly as 
possible.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., the 
electrolyte will last for the life of the battery 
when the vehicle is operated in a temperate cli-
mate. Your BMW  center will be glad to advise in 
all matters concerning the battery.
Charging 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 page220.
