Operation
When the vehicle is stationary or travelling at
v ery l
o
w speeds, the temperature displayed
may be slightly higher than the actual out-
side temperature as a result of heat coming
from the engine.
The temperatures measured range from

The ESC* has limits. It is important to realise
that ESC* is also subject to the laws of phys-
ics. ESC* will not be able to deal with all sit-
uations with which drivers may be faced. For
example, if the road surface changes sud-
denly then ESC* will not be useful in all ca-
ses. If the vehicle suddenly enters a section
covered by water, mud or snow then ESC*
will not provide assistance in the same way
as on dry ground. If the vehicle loses its grip
on the ground and moves on a film of water
(“aquaplaning”), the ESC* will not be able to
help the driver control the vehicle due to the
loss of adherence with the road surface pre-
venting braking and steering. If the vehicle is
driven through series of bends at high speed,
the ESC* will not always be as effective: ag-
gressive driving is not the same as slow driv-
ing.
Adjust your speed and driving style to suit vis-
ibility, and weather, road and traffic condi-
tions. ESC* cannot push the limits of the laws
of physics; improve the transmission available
or maintain the vehicle on the road if a lack of
driver attention creates an inevitable situa-
tion. Otherwise, ESC* assists in maintaining
vehicle control in extreme situations and uses
the movements of the steering made by the driver to maintain the vehicle moving in the
desired direction. If the v
ehicle is driven at
such a speed that it will leave the road before
ESC* can intervene then the system cannot
provide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC*. The ESC* is al-
ways on 1)
.
Anti-lock system (ABS)
ABS can prevent the wheels from locking dur-
ing braking until just before the vehicle stops
thus helping the driver to steer the vehicle
and maintain control. This means that, even
during full braking, the risk of skidding is re-
duced:

ing Running in Please observe the instructions for running-in
new components.
Running-in the engine
The engine needs t
o be run in o
ver the first
1,500 km. During its first few hours of running,
the internal friction in the engine is greater
than later on when all the moving parts have
bedded down.
How the vehicle is driven for the first 1,500 km
influences the future engine performance.
Throughout the life of the vehicle, it should be
driven at a moderate speed, especially when
the engine is cold, as this will reduce engine
wear and increase its useful life. Never drive
at extremely low engine speeds. Change
down to a lower gear when the engine no
longer runs “smoothly”. Up to 1,000 kilome-
tres the following instructions apply:
