Deactivating DSC
Press the button for at le ast 3 seconds until the
indicator lamp for DSC OFF lights up and DSC
OFF is displayed in the instrument cluster.
Dynamic Traction Control DTC and DSC have
been simultaneously de activated. Stabilizing
and drive-output promoting actions are no
longer executed.
In the same way as with a differential interlock,
even if DSC is deactivated, brake actions are
still performed to enhanc e drive output if the
drive wheels experience a significant loss of
traction.
To increase vehicle stab ility, activate DSC again
as soon as possible.
Activating DSC
Press the button again; th e indicator lamp in the
instrument cluster goes out.
For better control
If the indicator lamp flashes: the DSC
controls the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and
DSC OFF is displayed in the instrument
cluster: DSC is deactivated.
Dynamic Traction Control DTC
DTC is a version of DSC in which the drive out-
put is optimized for part icular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following sp ecial circumstances:
> When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
> When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
> When driving with snow chains
Activating DTC
Press the button; the indicator lamp for DSC
OFF lights up and TRACTION is displayed in
the instrument cluster.
For better control
If the indicator lamp flashes: DTC con-
trols the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and
TRACTION is displayed in the instru-
ment cluster: DTC is activated.
Deactivating DTC
Press the button again; th e indicator lamp in the
instrument cluster goes out.

Driving tipsThings to remember when driving
Things to remember when driving
Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. As a result, some equip-
ment described may not be available in a partic-
ular vehicle, for example due to the options or
national-market version selected. This also
applies to safety related functions and systems.
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follo w 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.
Avoid full-throttle operation and use of the
transmission's kickdown mode.
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 no t 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 clut ch 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 renewe d 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 vehicl e serviced regularly.
Remove any unneeded cargo
Additional weight increases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove unneeded additional mirrors, the roof
rack and the rear luggage rack after use.
Mounted parts affect th e vehicle's aerodynam-
ics and increase fuel consumption.
Close the windows and glass roof
An open glass roof or window causes higher air
resistance and thus increases fuel consump-
tion.
