GER Risk of fatal injury due topoison-
ous exhaust gases
If th eta ilpipe is bloc ked or su1cient ventila-
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter theve hi-

WARNING
ARNING Risk of accident due tothe
brake system overheating
If yo u lea veyour foot on the brake pedal when
driving, the brake system may overheat.
This increases the braking distance and the
brake system can even fail. #
Never use the brake pedal as a foot re st. #
Do not depress the brake pedal and the
accelerator pedal at the same time while
driving. &

Cruise control may be unable tomaintain the
stored speed on uphill gradients. The stored
speed is resumed when thegr adient evens out.
Change into a lo werge ar in good time on long and
steep downhill gradients. Take particular no teof
th is when driving a laden vehicle. By doing so, you
will make use of the engine's braking e.ect. This
re lie vesth e load on the brake system and pre-
ve nts the brakes from overheating and wearing
to oqu ickl y.
Do not use cruise control in thefo llowing situa-
tions:
R in tra1c situations which requ ire frequent
ch anges of speed, e.g. in heavy tra1c, on
winding roads
R on slippery roads. Accelerating can cause the
drive wheels tolose traction and theve hicle
could then skid.
R when visibility is poor
F F unction of t unction of t he limit
he limiter
er
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 anent: for long-term speed restrictions,
e.g. when driving in winter ty remode.
The variable limi ter is operated using the cor re-
sponding steering wheel buttons. You can store
any road speed from 20 km/h to250 km/h or up
to the set winter tyre limit. You can also per form
settings while theve hicle is stationary if theve hi-
cle has been star ted.
Obser vethe no tes on driving systems and your
re sponsibility; you may otherwise failto recognise
dangers (/ page 209).
