Traction Control

System (TCS)

The vehicle has a Traction Control
System (TCS) that limits wheel spin.
The system operates if it senses
that one or both of the drive wheels
are slipping or beginning to lose
traction. When this happens, the
system brakes the spinning wheel(s)
and/or reduces power to limit
wheel spin.
The system may be heard or felt
while it is working but this is normal.
To assist with directional control of
the vehicle, TCS automatically
comes on whenever the vehicle is
turned on. To limit wheel spin,
especially in slippery road
conditions, the system should
always be left on. But, TCS can be
turned off if needed.
When the vehicle is started and
begins to move, the system
performs several diagnostic checks
to ensure there are no problems.
The system may be heard or felt
while it is working. This is normal
and does not mean there is a
problem with the vehicle. The
system should initialise before the
vehicle reaches 32 km/h (20 mph).
In some cases, it may take
approximately 3.2 km (2 mi) of
driving before the system initialises.
The TCS may activate on dry or
rough roads or under conditions
such as heavy acceleration while
turning or abrupt changes in output
from the electric drive unit. When
this happens, a reduction in
acceleration may be noticed, or a
noise or vibration may be heard.
This is normal.

vehicle needs service.
Notice: Do not repeatedly brake
or accelerate heavily when TCS is
off. The vehicle's driveline could
be damaged.
