sufficient, brake gently. When doing so, make
sure that the vehicle is facing in the direction
of the line of fall.
RObserve the notes on driving in mountainous
terrain (Ypage 130).
RCheck that the service brake is working nor-
mally after along downhill stretch.
When driving at speeds below 37 mph
(60 km/h), off-road ABS is activated and the
front wheels lock cyclically during braking. The
digging-in effect achieved in the process
reduces the stopping distance on off-road ter-
rain. This limits steering capability.
Driving systems
Cruise control
General notes
Cruise control maintains aconstant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. Change into alower
gear in good time on long and steep downhill
gradients.
This is especiallyi mportant if the vehicle is
laden. By doing so, you will make use of the
braking effect of the engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain asteady
speed for aprolonged period. You can store any
road speed above 20 mph (30 km/h).
Do not activate cruise control on off-road jour-
neys.
Important safety notes
Cruise control can neither reduce the risk of an
accident if you fail to adapty our driving style nor
override the laws of physics. Cruise control can-
not take into account the road, traffic and
weather conditions. Cruise control is only an
aid. You are responsible for maintaining asafe
distance to the vehicle in front,f or vehicle
speed, for braking in good time and for staying in
lane.
Do not use cruise control:
Rin road and traffic conditions that do not allow
you to maintain aconstant speed, e.g. in heavy traffic, on winding roads or on rough
terrain
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rin poor visibility, e.g. due to fog, heavy rain or
snow
If there is achange of drivers, advise the new
driver of the speed stored.
iThe speed indicated in the speedometer
may differ slightly from the speed stored.

Tips for driving with DISTRONIC PLUS
Pay particular attention in the following traffic
situations:
RCornering, entering and exiting abend: the
ability of DISTRONIC PLUS to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or late.
RDriving on adifferent line: DISTRONIC PLUS
may not detect vehiclesw hich are not driving
in the middleoft heir lane. The distance to the
vehicle in front willbet oo short.
ROther vehicleschanging lane: DISTRONIC
PLUS has not detected the vehicle cutting in
yet. The distance to this vehicle willbet oo
short.
RNarrow vehicles: DISTRONIC PLUS does not
detect the vehicle in front on the edge of the
road because of its narrow width. The dis-
tance to the vehicle in front willbet oo short.
RObstacles and stationary vehicles:
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example,t he
