TEDama getotheve hicle
Damage totheve hicle may occur in thefo l‐
lowing cases:
RThe vehicle becomes grounded, e.g. on a
high curb or an unpa vedro ad.
RThe vehicle is driven toofast over an
obs tacle, e.g. a curb, speed bump or pot‐
hole.
RA heavy object strike sth e underbody or
parts of thech assis.
In situations such as this, the body, the
underbody, chassis parts, wheels or tires
could be damaged without the damage being
visible. Components damaged in this wa y
can unexpectedly fail or, in the case of an
accident, no longer withs tand thest ra in they
are designed to.
If th e underbody paneling is damaged, flam‐
mable materials such as lea ves, grass or
twigs can gather between the underbody and
th e underbody paneling. If these materials
come into conta ct withhot parts on the
ex haust sy stem, they may catch fire .
#Ha ve theve hicle checked and repaired
immediately at a qualified specialist
wo rkshop.

Speed control cruise control
Function of cruise control
Cruise cont rol accelerates and brakes theve hi‐
cle automatically in order tomaintain a pr evi‐
ously stored speed.
If yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Yo u can operate cruise cont rol with the cruise
control le ver.
If yo ufa ilto adapt your drivin gst yle, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible
fo rth e dis tance totheve hicle in front, forve hi‐
cle speed, for braking in good time and forst ay ‐
ing in your lane.
Sy stem limitations
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out. Do not use cruise control in
thefo llowing situa‐
tions:RIn traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
ROn slippery roads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
RWhen visibility is poor.
Operating cruise control
& WARNING Risk of accident due to
unkno wnstored speed
If yo u call up thestored speed and this is
lo we rth an your cur rent speed, theve hicle
decelerates.
If yo udo not kn owthestored speed, the
ve hicle could decelerate unexpectedly.
#Take into account the tra ffic situation
before calling up thestored speed.
#If th estored speed is not known, store
th e desired speed again.
Change into a lo werge ar in good time on long
and steep downhill gradients. Take particular
no te ofthis when driving a laden vehicle. By
doing so, youwill make use of the braking ef fect
of the engine. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐
ing and wearing tooqu ickl y.
