Add coolant mixed in the correct ratio

Twist the cap on again tightly .
Replacement engine coolant must conform to
exact specifications ¢
page 239 , Coolant .
We recommend using only coolant additive
G12++, G13 or in an emergency G12+. Do
not
use a different additive. In an emergency use
plain water until you can get the correct addi-
tive and can restore the correct ratio. This
should be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add cold antifree ze
and cold water only when the eng ine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mar k. Ex-
cess coolant will be forced out th rough the
press ure relief valve in the cap when the en-
gine becomes hot .
&_ WARNING
- The cooling system is under press ure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps .
-Tu rn off the engine and allow itt o cool
down.
- Protect your face, hands and arms from
escaping fluid and ste am by covering
the cap with a large, thick rag.
- Turn t he cap slowly and very carefully
in a counte r-clockwise direct ion while
app lying light, downward press ure on
the top of the cap.
- To avoid being burned, do not spill an-
tifreeze or coolant on the exhaust sys-
tem or hot engine parts . Under certa in
conditions, the ethylene glycol in en-
gine coolant can catc h fire.
- Antifreeze is poisonous. Always store an-
t ifreeze in its original container and well
out of the reach of children .
Checkin g and fillin g 241
- If you drain the coolant, it must be
caught and safely stored in a proper con-
tainer clearly marked "poison".
([) Note
- Coolant pollutes the environment and
could cause an engine fire. Excess cool-
ant will be forced out th rough the pres-
sure relief valve in the cap when the en-
gine becomes hot .
- If, in an eme rgency, only wate r can be
added, the correct ratio between water
and antifreeze ¢
page 239 must be re-
stored as soon as poss ible.
@) For the sake of the environment
Drained coolant should not be reused. Al-
ways dispose of used coolant while observ-
ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself.
The radiator fan is driven by the engine via the
V-belt. The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant .
An auxiliary electric radiator fan* switches on
and off depending on coolant temperature
and othe r vehicle operat ing condit ions.
After you switch the engine off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on aga in later by itself ¢
A , if
- the temperature of the engine coolant 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.
&_ WARNING
- To reduce the risk of perso nal injury nev-
er touch the radiator fan .
