WARNING
- Also, in vehicles with all wheel drive, adapt
your driving style to the curre nt road and
traffic conditions. Do not let the increased
safety provided tempt you into tak ing risks,
because th is increases the ris k of an acci-
dent.
- The brak ing ability of your vehicle is limited
to the tra ction of the wheels. In this way, it
is not diffe rent from a two whee l dr ive vehi-
cle . Do not be tempted to accelerate to a
high speed when the road is slippery this in-
creases the risk of an acc ident.
- Note that on wet stree t s, the front wheels
can "hyd roplane" if d riving at speeds that
are too high. Unlike front whee l drive
vehicles, the eng ine does not rev higher sud-
denly when the vehicle begins hydroplaning.
For this reason, pay attention to the road
condit ions regardless of you r speed to re-
duce the risk of an accident.
Energy
management
The starting ability is optimized
The energy managemen t system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle w it h a co nven ti onal energy sys -
tem is not driven for a long time, the batte ry is
d rained by equipment (for example t he immobi l-
izer) . In certain circumstances,
there could may
not be eno ugh energy to start the engine.
Your vehicle is equipped with a n intelligent ener -
gy management
system for distr ibuting electric i-
ty. This s ignificantly improves the starting ability
and increases the battery life.
The energy management
system Is made up of
battery diagnosis, idling current management
and dynamic energy management .
Battery diagnosis
The batte ry d iagnosis de t erm ines t he batt ery
cha rge level. The senso rs detect the battery, the
battery current, and the battery temperature.

The curren t cha rge level and the performance of
the battery are determined based on this .
Idling current management
The idling current ma nageme nt decreases the
energy used while parked. Wit h the engine
switc hed off , it m a nages t he energy dis t rib ut ion
to the d ifferent e lectrica l components.
Date from
batte ry diagnosis is taken into acco unt for this.
Depend ing on t he bat te ry charge level, ele ctrical
equipmen t is switched off one item after the ot h-
er, to preven t the bat t ery from draining and to
retain the starting ability .
Dynamic energy management
While driving , dynam ic energy manageme nt dis -
t ribu tes the a ppropr iate a mo unt of energy to the
electri ca l eq uipment. It contro ls the battery
charge level so that more energy is not used then
is being generated in order to maintain an opti-
mal battery charge level.

Tips
- Energy management cannot overcome the
laws of physics . Note that the charge level
and length of the battery life are limited.
- Whe n the sta rting ability is endangered, the

What you should know
Maintaining the starting ability is the highest
priority.
A lot of st ress is placed on the battery when dr iv-
ing sho rt d istances, in t raff ic, and at cold times
of the year . A lot of energy is used but litt le is
generated. It is also critical when the engine is
not running but e lectr ical equipment is sw itched
on. In th is case, energy is used but none is gener-
ated.
In sit uat ions like th is, ene rgy management
w ill
active ly regulated the dis t rib ut ion of energy.
Long periods without use
If you do not d rive your vehicle for sever al days or
weeks, electrica l equipment is gradua lly sca le d
back or sw itched off. This reduces ene rgy use and ..,.
