Driving Precautions - BMW E87 2009 Owner's Handbook Manual

Driving precautions

Running in
Moving parts require some time before they can
interact smoothly with one another. Please
comply with the following instructions, which
are intended to ensure that your car achieves its
optimum operating life and economy.
Engine and final drive
Observe the national speed limits in the country
in which you are travelling.
Up to 2000 km, approx. 1250 miles
Drive at varying road and engine speeds, but do
not exceed the following values:
> Petrol engine
4500 rpm, or 160 km/h or 100 mph
> Diesel engine
3500 rpm, or 150 km/h or 90 mph
Avoid full throttle and do not use the automatic
transmission kick-down.
From 2000 km, approx. 1250 miles,
onwards
Engine and road speeds can be gradually
increased.
Tyres
New tyres do not achieve their full road
grip immediately, for production reasons. You
should therefore drive in a restrained manner
for the first 300 km, approx. 200 miles.
Brakes
Brake pads and discs do not achieve a favoura-
ble wear and contact pattern until the car has
covered about 500 km, approx. 300 miles. Drive
with caution during this running-in period.
Clutch
The clutch needs to be run in for about 500 km,
approx. 300 miles, before it will operate with

maximum efficiency. Operate the clutch gently
while running it in.
After fitting new parts
The same running-in procedures should be
observed if any of the components mentioned
above have to be replaced in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on various factors. A number of measures, your
driving style and regular maintenance can influ-
ence fuel consumption and the burden on the
environment.
Remove loaded items that are not
required
Additional weight increases fuel consumption.
Remove attachment parts after use
After use, remove additional mirrors, roof racks
or rear racks that are not required. Attachment
parts on the vehicle diminish the aerodynamics
and increase fuel consumption.
Close windows and the glass sunroof
An opened glass sunroof or opened window
also increases the drag coefficient and thus the
fuel consumption.
Regularly check tyre pressure
Check and, if necessary, correct the tyre infla-
tion pressures at least twice a month and before
setting off on a longer journey.
Insufficient tyre inflation pressure enlarges the
rolling resistance and thus increases fuel con-
sumption and tyre wear.
