differential BMW 325xi TOURING 2003 E46 Owner's Manual

114Special operating instructions
Break-in proceduresTo ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following information.Engine and differentialUp to 1,250 miles/2,000 km:
Constantly vary both engine and vehicle
speeds, remembering not to exceed
4,500 rpm or 100 mph / 160 km/h dur-
ing this period.
Always obey all official speed limits.
Do not use full throttle, and avoid
pressing the accelerator beyond the
kickdown point during these initial
miles.
You can then proceed to increase both
engine and vehicle speeds once the ini-
tial 1,250 miles/2,000 km have elapsed.
You should also observe the same
break-in procedures if the engine or dif-
ferential should have to be replaced
later in the course of the vehicle's life.
TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
after an initial break-in period. We thus
ask you to drive with extra care during
the first 200 miles/300 km.
Always obey all official 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. before the brake pads and rotors
achieve the optimal pad-surface and
wear patterns required for trouble-free
operation and an extended service life
later on.
To break in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill – at a traf-
fic 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 come on
when the parking brake is set.
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 example – substan-
tially higher levels of pedal force will be
required to brake the vehicle. before the clutch starts to operate at
optimum efficiency. Remember to
engage the clutch carefully during this
initial period.

The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts/1 liter. Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.
Adding engine oilWait until the level has dropped to just
above the lower mark before adding oil.
However, you should never let the oil
drop below the lower mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, the automatic
transmission, the differential, and the
power steering system.<
Recommendation: have the oil changed
by your BMW center.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, any skin areas
that come into contact with oil should
be thoroughly washed with soap and
water.
Always store oil, grease, etc., out of
reach of children. Comply with all warn-
ing labels and information on contain-
ers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.<
Specified engine oilsThe quality of the engine oil is
extremely important for the function
and service life of an engine. Based on
extensive testing, BMW has approved
only certain grades of engine oil.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If an approved BMW High Performance
Synthetic Oil should be unavailable, you
may use small volumes of other syn-
thetic oils for topping up between oil
changes. Use only oils with the specifi-
cation API SH or higher.
