Things to remember when driving

Break-in period

Moving parts need breaking-in time to adjust to

each other. Please follow the instructions below

in order to achieve the optimal service life and

economy of operation for your vehicle.

Engine and differential

Always obey all official speed limits.

Up to 1,200 miles/2,000 km

Drive at varying engine and road speeds, but do

not exceed an engine speed of 4,500 rpm or a

road speed of 100 mph/160 km/h.

Do not drive with full-throttle operation, and do

not use the transmission's kickdown mode or

Launch Control.

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 after an initial break-in

period. 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. During this break-in period,

engage the clutch gently.

Following part replacement

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

An open window causes higher air resistance

and thus increases 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.
