Control of the vehicle Never coast with engine not
running
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.
Stop-start system 3 118.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must be increased. This will be achieved by
an idle boost which may be audible.
A message appears on the Uplevel
Display.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
116Driving and operatingUse only floor mats, which fit properly
and are fixed by the retainers on the
driver 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 77.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system. Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and
engine oil consumption may be
higher.
Additionally, the cleaning process of
the exhaust filter may take place more
often.
Exhaust filter 3 121.
Autostop may be inhibited to allow for charging of the vehicle battery.Ignition switch positions0:ignition off: Some functions
remain active until key is
removed or driver's door is
opened, provided the ignition was
on previously.1:accessory power mode: Steering wheel lock released, some
electrical functions are operable,

Driving and operating125To reduce the operating forces ofthe parking brake, depress the
brake pedal at the same time.
Control indicator R 3 76.
Brake assist If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, the brakes
remain on for a further 2 seconds. The brakes release automatically as soon
as the vehicle begins to accelerate or the 2 seconds holding time is over.
The hill start assist is not active during
an Autostop.Ride control systems
Traction Control system
The Traction Control system (TC) is a component of the Electronic Stability
Control (ESC).
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to
spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
128Driving and operatingInformation Centre and t
extinguishes when TC and ESC are
reactivated.
ESC is also reactivated the next time
the ignition is switched on.
