pery road sur faces
If yo u select theLO W RANGE off-road gear
on a slippe ryroad sur face, the wheels could
lose traction in thefo llowing situations:
R ifyo ure lease the accelera tor pedal when
th eve hicle is in motion.
R if off-road ABS inter venes when braking.
If th e wheels lose traction, it will no longer be
possible tosteer theve hicle. #
Never select theLO W RANGE off-road
ge ar when driving on slippe ryroad sur‐
fa ces. &

in thefo llowing situations to
impr ove traction:
R When using snow chains.
R In deep sn ow.
R On sand or gr avel.
% Spinning the wheels results in a cutting
action, which enhances traction.
If th e÷ ESP®

ETS/4ETS (Elect ronic Traction Sy stem)
ETS/4E TStraction control is pa rtof ESP ®
and
makes it possible topull away and accelerate on
a slippe rycar riag ew ay. If
yo u select theF orG drive prog ram, a
special ETS sy stem specifically suited tooff-road
te rrain is automatically activated.
ETS/4E TScan impr ovetheve hicle's traction by
inter vening in thefo llowing ways:
R The drive wheels are braked individually if
they spin.
R More drive torque is transferred tothe wheel
or wheels with traction.
Influence of drive prog rams on ESP ®
The drive prog rams enable ESP ®
to adapt todif‐
fe re nt we ather and road conditions as well as
th e driver's prefer red driving style. You can
select the drive prog rams using theDY NA MIC

if th e driver operates a turn signal indicator.
Assis tance when changing lanes is pr ovided if all
th efo llowing conditions are me t:
R You are driving on a mo torw ay orroad with
multiple lanes in the direction of tr avel.
R The neighbouring lane is separated bya bro‐
