Operation, care and maintenance -> Break-in procedure for your BMW 5 Series 1995-2003

118nBreak-in procedure  
To ensure that your vehicle provides  
maximum economy throughout a long  
service life, we request that you

Brake system  
Due to technical factors associated  
with their manufacture, tires do not  
achieve their full traction potential until disks achieve the optimal pad-surface  
Approximately 300 miles (500 km)  
must elapse before the brake pads and

For this reason, drive with extra care

and wear patterns required for trouble-

on.  
Because of its engineering design,  
the BMW M5 is an especially high-  
quality vehicle. To protect your own  
investment, we recommend that you  
follow the break-in instructions care-  
fully. By doing so, you will create the  
basis for optimal service life of the  
vehicle.<

drums, apply the parking brake lightly  
when coasting to a standstill (at a traffic  
signal, for instance), provided that  
traffic conditions allow you to do so. To  
avoid corrosion, repeat this procedure  
from time to time.  
When the vehicle is operated on  
wet or slushy roads, a wedge of  
water may from between the tire and  
the road surface. This phenomenon is  
referred to as aquaplaning, or hydro-  
planing, and can lead to partial or  
complete loss of traction, vehicle  
control and braking effectiveness.  
Reduce your speed on wet roads.<  
Engine and differential  
Up to 1,200 miles (2,000 km):  
Drive at varying engine speeds and  
road speeds, but do not exceed  
5,500 RPM or 105 mph (170 km/h)  
during this period.  
The brake lamps do not come on  
when the parking brake is applied.  
Vacuum for the brake system servo unit  
on your BMW is available only when the  
engine is running. When you move the  
vehicle with the engine shut off – when  
towing, for instance – substantially  
higher levels of pedal force will be  
required to brake the vehicle.<  
Obey all applicable local, state, provin-  
cial or federal speed limits.  
Do not depress the accelerator pedal to  
the full-throttle position.  
Following the break-in inspection at  
1,200 miles (2,000 km), you can gradu-  
ally increase engine or road speeds.  
Clutch  
The clutch will also begin to function  
optimally after approx. 300 miles  
(500 km). During the run-in period, treat  
the engine with care and do not engage  
the cluth at high engine speeds.  
You should also comply with these  
break-in procedures if the engine or  
differential is replaced later in the  
course of the vehicle service life.
