When l
ess than 90 days for the review of the
compressed natural gas tanks (CNG), when
the ignition is switched on, the instrument
panel display will a reminder for review of
the gas tanks and an audible warning will be
emitted.
As approaches the service date of inspection
of the gas tanks, the message and the audi-
ble warning will stop modify accordingly.
Check a service warning
With the ignition switched on, the engine off
and the vehicle at a standstill, the current
service notification can be read:

Keyless Access is a key-free locking and igni-
tion system to unlock and lock the vehicle
without actively using its key. To do this, all
that is required is to have a valid vehicle key in
the detection area where you are attempting
to access the vehicle

opened with the ignition switched on. WARNING

Start and driving
Since the luggage rack increases the aer o-
dynamic dr ag
of the vehicle, you should re-
move it when not needed. At speeds of
100-120 km/h (62-75 mph), this will save 12%
of fuel.
Save electrical energy
The engine drives the alternator, thereby
generating electricity. This implies that any
increase in power consumption also increa-
ses fuel consumption! For this reason, switch
off any unneeded electrical devices. Devices
that use a lot of electricity includes the blow-
er at a high setting, the rear window heating
or the seat heating*.
Power management
This system helps to ensur
e relia-
ble starting The power management controls the distri-
bution of el
ectrical ener
gy and thus helps t

o
ensure that there is always enough power
available to start the engine.
If a vehicle with a conventional electrical sys-
tem is left parked for a long time, the battery
will gradually lose its charge because certain
electrical devices, such as the electronic
gearbox lock continues to draw current even
when the ignition is off. In some cases there may not be enough power available to start
the engine.
Your v

ehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy. This signifi-
cantly improves reliability when starting the
engine, and also prolongs the useful life of the
battery.
The main functions incorporated in the power
management system are battery diagnosis,
residual current management and dynam-
ic power management.
Battery diagnosis
The battery diagnosis function constantly
registers the condition of the battery. Sensors
detect the battery voltage, battery current
and battery temperature. This enables the
system to calculate the current power level
and charge condition of the battery.
Residual current management
The residual current management reduces
power consumption while the vehicle is
parked. It controls the supply of power to the
various electrical devices while the ignition is
switched off. The system takes the battery di-
agnosis data into consideration.
Depending on the power level of the battery,
switch off the individual electrical devices
one after the other to prevent the battery from losing too much charge and to ensure
that the engine can be started r
eliably.
Dynamic power management
While the vehicle is moving, this function dis-
tributes the available power to the various
electrical devices and systems according to
their requirements. The power management
ensures that on-board systems do not con-
sume more electrical power than the alterna-
tor can supply, and thus maintains the maxi-
mum possible battery power level. Note
