Drivin g and Operation
Electric Power Steering (EPS) 3
Switching off the engine
Driving hints
If the Electric Power Steering fails when
being towed with the engine switched off,
the vehicle can still be steered, but
considerably more force is required.
When you switch off, fans in the engine
compartment may continue running for a
time to cool the engine.
The first 600 miles (1000 km)
Drive your vehicle at various speeds.
Do not use full throttle. Never allow the
engine to labour at low revs.
If the engine temperature is very high, e.g.
after driving in mountainous terrain:
Allow the engine to idle for approx.
two minutes in order to prevent heat
accumulation.
Driving in mountainous terrain or with a
caravan / trailer
The cooling fan is electrically operated. Its
cooling power is therefore independent of
the engine speed.
Make good use of all gears.
Depress the accelerator pedal a maximum
of approx. three quarters of the available
pedal travel in all gears.
Vehicles with turbocharged engine:
After runningat high engine speeds or high
engine loads, operate the engine briefly at
a low load or run in neutral for approx.
30 seconds before switchingoff, in order to
protect the turbocharger.
Do not drive faster than three quarters of
maximum speed.
Since a considerable amount of heat is
generated at high engine speeds and less
at slower speeds, do not shift down when
climbing hills while the vehicle is stillcoping
with the gradient in the higher gear.
Do not brake unnecessarily hard for the
first 125 miles (200 km).
Never coast with engine not running
Many units will not function in this situation
(e.g. brake servo unit, Electric Power
Steering (EPS) 3). Driving in this manner is
a danger to yourself and others.
Driving with a roof load
Save energy – more miles / kilometres
Please observe the running-in hints on the
previous page and the tips for energy
saving on the following pages.
Do not exceed the permissible roof load,
see page 214. For reasons of safety,
distribute the load evenly and secure it
properly with retaining straps.
Brake servo unit
Good, technically correct and economical
driving ensures maximum durability and
performance for your vehicle.
When the engine is not running, the brake
servo unit is no longer effective once the
footbrake has been depressed once or
twice. Braking effect is not reduced, but
significantly greater force is required for
braking.
Adjust tyre pressure to load conditions.
Do not d rive faster than 75 mph
(120 km/h). Check and retighten the straps
frequently. Observe country-specific
re gulations .
