Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
!
A function or performance test should only
be carried out on a two-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
If you fail to adapt your driving style or if you are
inattentive, the all-wheel drive system can nei-
ther reduce the risk of an accident nor override
the laws of physics. The all-wheel drive system
cannot take road, weather and traffic conditions
into account. The all-wheel drive system is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed and for
braking in good time.
4ETS ensures permanent drive for all four
wheels, and together with ESP
vehicle's traction.
If a driven wheel spins due to lack of traction:
When pulling away, make use of the traction

accelerator pedal as far as necessary.
While driving, slowly take your foot off the
R
accelerator pedal
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains
( page 249). This is the only way to get the full
Y
benefit from the all-wheel drive system.
For information on "Driving off-road", see
( page 137).

LOW RANGE transmission ratio

General notes
The LOW RANGE transmission ratio assists you
when driving on difficult terrain. If you engage
LOW RANGE, the engine's performance charac-
teristics and the automatic transmission's shift-
ing characteristics are adjusted accordingly.
The transmission ratio from the engine to the
wheels is around 40% lower than in the on-road
position. This increases the drive torque.
