WARNING
ARNING Risk of an accident caused by

Brake Assist
Ac tive Brake Assist cannot alw ays clear lyiden-
tify objects and complex tra1c situations.
In such cases, Active Brake Assist might:
R Give a warning or brake without reason
R Not give a warning or not brake
Ac tive Brake Assist is only an aid. The driver is
re sponsible for maintaining a su1ciently safe
distance totheve hicle in front, vehicle speed
and for braking in good time. #
Always pay careful attention tothe tra1c
situation; do not relyonActive Brake
Assist alone. #
Be prepared tobrake or swer veif neces-

vethe system limitations of Active Brake
Assist. Due tothe nature of the system, complex

Cruise control accelerates and brakes theve hicle

Cruise cont rol may be unable tomaintain the

is resumed if the uphill gradient evens out and the
ve hicle's speed does not fall below 30 km/h.
On long and steep downhill gradients, you should
ch ange down toa lo werge ar in good time. Take
particular no teof this when driving a laden vehicle.
By doing so, you will make use of the engine's
braking e.ect. This will take some of the strain o.

re coding the control units in theve hicle, the func-

Do not use cruise control in thefo llowing situa-
tions:
R in tra1c situations where frequent speed
changes are requi red, e.g. in heavy tra1c or on
winding roads
R o.-road or on construction sites
R on slippery or slick roads, as the drive wheels
can lose traction when accelerating and the
