To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following:
Engine and differentialUp to 1,200 miles (2,000 km):
Drive with varying engine and road
speeds, but do not exceed 4,500 rpm
or 100 mph (150 km/h).
Comply with local and state maximum
speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the
"Kickdown" point.
After you have driven 1,200 miles
(2,000 km), you can gradually increase
the engine and road speeds.
You should also comply with these
break-in procedures if the engine or
differential is replaced later in the
course of the vehicle's service life.
TiresDue to technical factors associated with
their manufacture, tires do not achieve
their full traction potential until an initial
break-in period has elapsed. You should
therefore drive with extra caution during
the initial 200 miles (300 km).
Comply with 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 systemApprox. 300 miles (500 km) must
elapse before the brake pads and discs
achieve the optimal surface and wear
pattern.
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 booster
on your BMW is available only when the
engine is running. When you move the vehicle with the engine off – for instance
,
by towing – substantially higher levels
of pedal force will be required to brake
the vehicle.<
ClutchThe clutch will reach optimal function
after approx. 300 miles (500 km). Shift
gears carefully during the break-in
period.

Engine oil To check oil level1 Park the vehicle on a level surface.
2 Switch the engine off after it has
reached normal operating tempera-
ture.
3 After approx. 1 minute, pull the
dipstick out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material.
4 Push the dipstick carefully all the way
into the guide tube and pull it out
again.
5 The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.36mde790
The space between the two marks on
the dipstick corresponds to approx.
1.4 US quarts (1.3 liter). Do not fill
beyond the upper mark on the dipstick.
Excess oil will damage the engine.36mde791
To add oilWait until the level has dropped to just
above the lower mark before adding oil.
Do not wait until the oil drops 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, differential and
the power steering system.< 36mde792

Limited slip differential
*
With unfavorable road conditions, the
drive forces that should be transferred
may not be accommodated by the
traditional differential, and therefore
one wheel may spin. This wheelspin is
largely avoided by the limited slip differ-
ential (cut-off value approx. 25X).
Under actual driving conditions, this
means better traction characteristics
when starting and accelerating (under
adverse road conditions) and during
performance-oriented driving on
winding roads.However, in the case of extremely
dynamic driving, the vehicle may tend
at the same time to spin around its
vertical axis in the vehicle center of
gravity on road surfaces with different
adhesion characteristics. Controlling
this rotation tendency places greater
demands on the driver and therefore
requires special alertness.
The limited slip differential is active
during actual driving without the driver
taking action.
