R Drive at no more than 10 km/h.
R Obser vethe maximum permissible ford ing

R Ensure that a bow wave does not form asyou
drive. R
Do not stop in thewate r and do not switch

Driving in mountainous terrain
Also obser vethefo llowing information when
driving in moun tainous terrain:
R Obse rveth eva lues of the approach/depar‐

R Vehicle steerability while braking is ensured.
If ABS inter venes when braking, you will feel a

into account road, weather or traf fic conditions.
Cruise control is only an aid. The driver is

Sy stem limits
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lo werge ar in good time on long

doing so, you will make use of the engine's brak‐

Do not use cruise control in thefo llowing situa‐

R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
R Ifyo u are driving when visibility is poor.
Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for speed restrictions, e.g. in built-
up areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving in winter tyre mode. 238

can set this speed with the permanent limiter.
Yo u do this by limiting the speed toava lue

media sy stem (/ page241).

appears in the multifunction displa y.When you

Regulation) Fu
nction of DSR (Downhill Speed Regulation)
DSR is an aid toassist you when driving down‐
hill. It keeps the speed of tr avel at the selected
ta rget speed. The steeper the downhill gradient,
th e greater the DSR braking ef fect on theve hi‐
cle. On flat stre tches of road and uphill gradi‐
ents, the DSR brakes theve hicle minimally or
not at all.
When DSR is activated and the transmission is in
position h,kori, DSR controls the driving
speed. The target speed can be set toava lue
between 2 km/h and 18km/h. By braking or
accele rating, you can drive at a higher or lo wer
speed than theta rget speed at any time.
DSR is deactivated automatically if you drive at
speeds greater than 45 km/h or select drive Driving and parking
