Control of the vehicleNever coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 137.
Idle boost
If charging of the vehicle battery is
required due to vehicle battery
condition, the power output of the
generator must be increased. This will be achieved by an idle boost which
may be audible.
On vehicles with Uplevel-Display or
Uplevel-Combi-Display, a message
appears in the Driver Information
Centre.Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
Steering If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require a higher
or lower steering effort.
Control indicator c 3 96.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
