The braking e.ect is limited on salt-treated roads.
Therefore, obser vethefo llowing no tes:
R due tosalt build-up on the brake disks and
brakepads, the braking distance can increase
considerably or result in braking only on one
side
R maintain a much greater safe distance tothe
ve hicle in front
To remo vesalt build-up:
R brake occasionally while paying attention to
th e tra1c conditions
R carefully depress the brake pedal at the end of

Wa ter which has entered into theve hicle can
damage the engine, electrics and transmission.
Wa ter can also enter the air intake of the engine
and cause engine damage.
Obser vethefo llowing if you must drive thro ugh
wa ter:
R The water,when calm, may only reach the
lo we r edge of theve hicle body.
R Drive at walking pace at most; water can oth-
erwise enter theve hicle interior or engine
compartment. R
Vehicles tr avelling in front, or oncoming vehi-
cles, can create waves which may exceed the
maximum permissible dep thofthewa ter.

eering
ing The
rear axle steering is an elect romechanical
auxiliary steering on there ar axle which adjusts
th e steering of there ar wheels according tothe
position of the front wheels, depending on the
speed. This results in greater manoeuvrability and
impr oved driving stability, e.g. when cornering.
Re ar axle steering has thefo llowing characteris-
tics:
R reduced steering e.ort and turning circle
re sulting in reduced parking e.ort
R impr oved driving stability, e.g. when cornering

ECO Assist can function even more precisely if
th ero ute is adhered towhen routeguidance is
active. The basic function is also available without
active route guidance. Not all information and
tra1c situations can be fore seen. The quality
depends on the map data.
ECO Assist is only an aid. The driver is responsible
fo rke eping a safe distance from theve hicle in
front, forve hicle speed and for braking in good
time. The driver must be ready tobrake at all times ir
respecti veof whe ther the system inter-
