Corrosion on brake rotors
When the vehicle is driven only occasionally, 
during extended periods when the vehicle is not 
used at all, and in operating conditions where 
brake applications are less frequent, there is an 
increased tendency for corrosion to form on 
rotors, while contaminants accumulate on the 
brake pads. This occurs because the minimum 
pressure which must be exerted by the pads 
during brake applications to clean the rotors is 
not reached.
Should corrosion form on the brake rotors, the 
brakes will tend to respond with a pulsating 
effect that even extended application will fail to 
cure.
When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits 
under the vehicle. Traces of condensed water 
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their 
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage 
develops inside the tires. In some situations, 
this can result in sudden loss of tire pressure.<
Make sure that no liquids are spilled or 
leak from their containers in the cargo 
area, as this could result in damage to the vehi-
cle.<
Determining loading limit
1.Locate the following statement on your 
vehicle's placard
*:
The combined weight of occupants 
and cargo should never exceed 
XXX kg or YYY lbs. Otherwise, overloading 
can result in damage to the vehicle and 
unstable driving conditions.<
2.Determine the combined weight of the 
driver and passengers that will be riding in 
your vehicle.
3.Subtract the combined weight of the driver 
and passengers from XXX kilograms or YYY 
pounds.
4.The resulting figure equals the available 
amount of cargo and luggage load capacity. 
For example, if the YYY amount equals 
1,400 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is 
650 lbs: 
1,400 lbs. minus 750 lbs. = 650 lbs.
5.Determine the combined weight of luggage 
and cargo being loaded on the vehicle. That 
weight may not safely exceed the available 
cargo and luggage load capacity calculated 
in step 4.
6.If your vehicle will be towing a trailer, part of 
the load from your trailer will be transferred 
to your vehicle. Consult the manual for 
transporting a trailer to determine how this 
may reduce the available cargo and luggage 
load capacity of your vehicle.

Tire inflation pressures
Information for your safety
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.
Check the tire inflation pressure regularly 
and correct it, if necessary: at least twice a 
month and before starting long trips. If you fail 
to observe this precaution you may be driving 
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age 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 seriously 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
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 is higher.
After correcting the tire inflation pressure, 
reset the Tire Pressure Monitor, refer to 
page90, or reinitialize the Flat Tire Monitor, 
refer to page88.<
Inflation 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 recom-
mended by BMW; a list of these is available 
from your BMW center.<
For correct identification of the right tire infla-
tion pressures, observe the following:>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up 
to 100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h 
and to achieve optimum driving comfort, adjust 
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of 
100 mph or 160 km/h.
These tire inflation pressures can also be found 
on the driver's side door post when the driver's 
door is open.
The maximum permissible speed for 
these tire pressures is 100 mph or 
160 km/h. Do not exceed this speed; otherwise, 
tire damage and accidents could occur.<
Tire inflation pressures for driving 
above 100 mph or 160 km/h
In order to drive at maximum speeds in 
excess of 100 mph or 160 km/h, adjust 
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds including those 
exceeding 100 mph or 160 km/h. Otherwise, 
tire damage and accidents could occur.<
Observe all national and local maximum speed 
limits; otherwise, violations of the laws could 
occur.
