BMW 2004 525i Sedan Manual Do Proprietário

106

To ensure that your vehicle continues to 
provide optimized economy of operation 
throughout an extended service life, we 
request that you devote careful attention to 
the following section. 

Up to 1,200 miles/2,000 km: 
You should attempt to vary both vehicle 
and engine speeds. Until the break-in 
period has been completed, you should 
also refrain from exceeding an engine 
speed of 4,500 rpm or a driving speed of 
100 mph/160 km/h. 

Always obey all official speed limits. 

Avoid full-throttle operation and use of the 
transmission's kickdown mode during 
these initial miles. 

Once you have driven 1,200 miles/
2,000 km, the engine and vehicle speeds 
can be gradually increased. 

You should also comply with these break-in 
procedures should the engine or differen-
tial need to be replaced at a later point. 

Do not use the acceleration assistant dur-
ing the break-in period. 

Due to technical factors associated with 
their manufacture, tires do not achieve their 
full traction potential until after an initial 
break-in period. Therefore, drive reservedly 
during the first 200 miles/300 km. 

Brakes require an initial break-in period of 
approx. 300 miles/500 km to achieve opti-
mized contact and wear patterns between 
brake pads and rotors. 

The function of the clutch is only at its opti-
mized level after a distance driven of 
approx. 300 miles/500 km. During this 
break-in period, engage the clutch gently. 

Extreme temperatures occur at the 
catalytic converter on this and every 

catalyst-equipped vehicle. Do not remove 
the heat shields installed adjacent to vari-
ous sections of the exhaust system, and 
never apply undercoating to them. When 
driving, standing at idle and while parking 
take care to avoid possible contact 
between the hot exhaust system and any 
highly flammable materials such as hay, 
leaves, grass, etc. Such contact could lead 
to a fire, and with it the risk of serious prop-
erty damage as well as personal injury.

Condensation forms in the air conditioner 
system during operation, and then exits 
under the vehicle. Traces of condensed 
water under the vehicle are thus normal.

Fold in the exterior mirrors, refer to

aged due to the width of the vehicle. 

When driving on wet or slushy roads, 
reduce road speed. If you do not, a 

wedge of water can form between tires and 
road surface.This phenomenon is referred 
to as hydroplaning, and is characterized by 
a partial or complete loss of contact 
between the tires and the road surface, ulti-
mately undermining your ability to steer 
and brake the vehicle.
