Things to remember when driving

Break-in procedures

Moving parts need to be given some time until
they can interact smoothly with one another. To
ensure that your vehicle provides maximum
economy throughout a long service life, we
request that you observe the following.
Always obey all official speed limits.

Engine and differential

Up to 1,200 miles/2,000 km

Drive at varying engine and road speeds, but do
not exceed 4,500 rpm or 100 mph/160 km/h.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kickdown point.

After driving 1,200 miles/2,000 km

Engine and vehicle speeds can be gradually
increased.

Tires

Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until an initial break-in period has
elapsed. Therefore, drive cautiously during the
first 200 miles/300 km.

Brake system

Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.

Clutch

The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. Shift gears carefully during
the break-in period.

After replacing components

The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.

Saving fuel

The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicle serviced regularly.

Remove any unneeded cargo

Additional weight increases fuel consumption.

Remove any mounted parts after you
have finished using them

Remove additional mirrors and the luggage rack
when they are no longer in use. Mounted parts
affect the vehicle's aerodynamics and increase
fuel consumption.

Close both windows

Open windows cause higher air resistance and
thus increase fuel consumption.

Check tire inflation pressure regularly

Check the tire inflation pressure at least twice a
month and before embarking on a long journey,
and correct it if necessary.
Low tire inflation pressure causes higher rolling
resistance and thus increases fuel consumption
and tire wear.

Set off immediately

Do not let the engine warm up while the car is
still standing, but set off immediately at moder-
ate engine speed. This is the fastest way for the
cold engine to reach its operating temperature.
