The all- wheel drive system distributes the driving
power variably to the front and rear axle. It works
together with selective whee l torque contro l,
which activates when driving through curves
c:::;,
page 142. With the sport differentia l", power
distribution to the rear wheels is variable and can
be adjusted using the dr ive select
¢ page 128 .
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow-
erful and has excellent driving characteristics
both under normal dr iving condit ions and on
snow and ice. Always read and fo ll ow safety pre-
cautions

/1),.. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in w inter con-
ditions . However, using winter or all season tires
on
all four
wheels in the winter is recommended,
because this will improve the
braking
effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c:::;,
page 346, Snow chains .
Replacing tires
For vehicles w ith all wheel dr ive, only wheels w ith
the same rolling circumference should be used.
Avoid using tires w ith different tread depths

WARNING
- Also, in vehicles with al l wheel drive, adapt
your dr iving style to the current road and
traffic conditions. Do not let the increased
safety provided t empt you into taking risks,
because this increases the risk of an acci-
dent.
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two whee l drive vehi-
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be-
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front wheel drive
Intelligent Technology
vehicles, the engine does not rev higher sud-
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci-
dent.
Energy management
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This sign ificantly improves the start ing ability
and increases the vehicle battery life.

Tips
- If you dr ive short distances frequently, the
vehicle battery may not charge enough
w hile driving . As a result, convenience func-
tions for electr ical equipment may be tem-
porarily unavailable.
- The vehicle battery w ill gradually drain if
the vehicle is not driven for long per iod s of
time, or if electr ical equipm ent is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment wi ll be reduced or
switched off.
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped with an Event Data Re-
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
t ions, such as an airbag deployment or hitt ing a
road obstacle, data that w ill assist in understand-
ing how a vehicle's systems performed. The EDR
is designed to record data related to vehicle dy-
nam ics and safety systems for a short per iod of
time, typ ically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
- How various systems in your veh icle were oper-
ating;
- Whether or not the driver and passenger safety
belt s were buckled/fastened; .,.
