A WARNING
- The rear view camera does not show the
entire area behind the vehicle
¢
page 120, fig. 133. Watch out espe­
c ially for small children and animals. The
rear view camera cannot always detect
them, posing risk of an accident!
- Please note that objects not touch ing the
ground can appear to be further away
than they really are (for example, the
bumper of a parked vehicle, a trailer
hitch, or the rear of a truck). In this case,
yo u should not use the help lines to he lp
with parking, which poses danger of an
accident!
{[) Note
-Low obstacles already signaled by a
warning can disappear from the system's
detection range as they are approached
and will not continue to be signaled. Ob­
j ects such as barrier chains, trailer draw
bars, thin pa inted vertical poles or fen­
ces may not be detected by the system, posing risk of damage.
- In the MMI display, the direction of trav­
el of the vehicle rear is represented de­
pending on the steering wheel angle.
The vehicle front swings out more than
the vehicle rear. Maintain plenty of dis­
tance from an obstacle so that your out­
s ide mirror or a corner of your vehicle
does not collide with any obstacles -dan­
ger of accident!

220 Check ing and filling
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure re lief valve in the cap when the en ­
g ine becomes hot.
A WARNING
- The coo ling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps.
- Turn
off the engine and a llow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully in a co unte r-clockwise d irection while
apply ing light, downward press ure on
the top of the cap.
- To avoid being burned, do not spi ll an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certa in
conditions, the ethylene glyco l in en­
g ine coolant can ca tch f ire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its original container and we ll
o ut of the reac h of children.
- If you drain the coolant, it must be
caught and safely stored in a p roper con­
ta iner clear ly ma rked "poison".
(D Note
- Do not add coolant if the expansion tan k
i s empty. A ir could enter the cooling sys­
tem and damage the eng ine. If this is
the case, do not continue driving. Seek professional assistance.
- Coolant po llutes the e nv ironment and
could cause an engine fire. Excess coo l­
ant will be forced ou t through the pres ­
su re rel ief v alve in the ca p when the en­
gine becomes hot .
- If, in an emergen cy, only water can be
added, the correct ratio be twee n wa te r
and antifr eeze¢
page 218 must be re ­
stored as soon as possib le .
{® For the sake of the environment
D rained coo lant should not be reused . A l­
ways d ispose of used coolant whi le observ­
i ng a ll environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself
T he rad iator fan is driven by the engine v ia the
V-belt. The viscous clutch regulates the spee d
of the fan acco rding to the temperature of the
coolant.
An a uxiliary electric radiator fan* sw itches on
and
off depending on coolant temperature
and othe r vehicle ope rat ing condit ions .
A ft er yo u sw itch the eng ine
off, the aux iliary
f an can continue running for up to 10 m inutes
- even wit h the ignition
off. It can even switc h
on again later by itself¢.&. , if
- t he temper ature of the engine coo lant rises
due to the heat build -up from the engine in
the engine compa rtment, or
- the engine compa rtment heats up because
the vehicle is parked in intense sunlig ht.
A WARNING ~
- To reduce the risk of perso na l inj ury nev -
er touch the radiator fan.
- The a uxiliary electric fan is tempe rat ure
contro lled and can sw itch on sud denly
even when the engine is not running.
- The a uxiliary radiator fan switches on a u­
tomatically when the engine coo lant
reac hes a certa in temperature and will
continue to ru n until the coolant temper­
ature drops.
