Break-in procedures
To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following instructions:
Engine and differential
Up to 1,200 miles/2,000 km:
Drive at varying engine speeds and
road speeds, but do not exceed
4,500 rpm and the following road
speeds during this initial period:
6-cylinder engines: 100 mph/160 km/h
8-cylinder engines: 106 mph/170 km/h
Obey your local and state maximum
speed limits.
Avoid full-throttle operation and use of
the transmission's kickdown mode dur-
ing 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 one of the differentials be replaced
later in the course of the vehicle's ser-
vice life.
Tires
Due to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
after an initial break-in period. There-
fore, drive reservedly during the first
200 miles/300 km.
Obey your local and state maximum
speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as hydroplaning and can
lead to partial or complete loss of trac-
tion, vehicle control and braking effec-
tiveness. Reduce your speed on wet
roads.<
Brake system
Brakes require an initial break-in period
of approx. 300 miles/500 km to achieve
optimal contact and wear patterns
between brake pads and rotors.
To break in the separate handbrake
drums, apply the handbrake 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 proce-
dure from time to time.
The brake lamps do not light up
when the handbrake 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 switched off –
when towing, for instance – substan-
tially higher levels of pedal force will be
required to brake the vehicle.<
