Break-in procedures
To ensure that your vehicle provides 
maximum economy throughout a long 
service life, we request that you 
observe the following suggestions: 
Engine and axle drive 
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:
BMW X5 3.0i: 100 mph (160 km/h)
BMW X5 4.4i: 106 mph (170 km/h)
Obey your local and state maximum 
speed limits. 
Refrain from using full throttle and avoid 
pressing the accelerator beyond the 
kickdown point. 
Once you have driven 1,200 miles 
(2,000 km), engine and vehicle speeds 
can gradually be increased.
You should also comply with these 
break-in procedures if the engine or 
one of the axle drives is replaced later 
in the course of the vehicle service life.
Tires
Due to technical factors associated 
with their manufacture, tires do not 
achieve their full traction potential until 
an initial break-in period has elapsed. 
For this reason, drive with extra care 
during the initial 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 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.

Brake system
Approx. 300 miles (500 km) must 
elapse before the brake pads and discs 
achieve the optimal pad-surface and 
wear patterns required for trouble-free 
operation and long service life later on. 
To break in the separate parking brake 
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 proce-
dure from time to time. 
The brake lamps do not light up 
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.
