Vehicle Stability Management
(VSM)
The Vehicle Stability Management (VSM)
is a function of the Electronic Stability
Control (ESC) system. It helps ensure the
vehicle stays stable when accelerating
or braking suddenly on wet, slippery and
rough roads where traction over the four
tyres can suddenly become uneven.
WARNING
Take the following precautions when
using the Vehicle Stability Management
(VSM):
[ $ / : $ < 6 F K H F N W K H V S H H G D Q G W K H
distance to the vehicle ahead. The
VSM is not a substitute for safe
driving practices.

conditions. The VSM system will not
prevent accidents. Excessive speed
in bad weather, slippery and uneven
roads can result in severe accidents.

Your vehicle may be equipped with
the ISG system, which reduces fuel
consumption by stopping and restarting
the engine automatically.

as the starting conditions are met.
NOTICE
When the engine automatically starts
by the ISG system, some warning lights
(ABS, ESC, ESC OFF, EPS or Parking
brake warning light) may turn on for a
few seconds. This happens because of
low battery voltage. It does not mean
the system is malfunctioning.
