Driving and operating135Driving hints
Control of the vehicle
Never 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 battery is required
due to battery condition, the power
output of the generator has to be
increased. This will be achieved by an idle boost which may be audible. A
message is displayed in the Driver
Information Centre.Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Use only floor mats, which fit properly
and are fixed by the retainers on the
driver's side.
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 increased
effort.
Control indicator c 3 90.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.
Ground clearance
Due to the reduced ground clearance,
the vehicle can be damaged
depending on the vehicle loading and
appearance of the ground. Take
special care and drive slowly on steep driveways, entry and exit of parking
garages, high kerbs and uneven
surfaces. If possible, drive diagonally
with one wheel after another when running over kerbs or uneven
surfaces.
