222 Checking and filling
pressure relief valve in the cap when the en
gine becomes hot.
.&_ WARNING
- The cooling system is under pressure and
can get
very hot. Reduce the risk of
sca lding from hot coolant by following
these steps .
- Turn off the eng ine and a llow it to cool
down.
- Protect your face, hands and arms from
escap ing flu id and steam by cover ing
the cap with a large , thick rag .
- Tu rn the cap slowly and
very carefully
in a counter -clockwise direction while
applying light, downward pressure on
the top of the cap .
- To avo id being burned, do not sp ill an
tifreeze or coolant on the exhaust sys
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en
g ine coolant can catch fire.
- Antifreeze is poisonous. Always store an
t ifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con
ta iner clearly marked "poison".
(D Note
- Coolant po llutes the environment and
could cause an engine fire. Excess coo l
ant will be forced out through the pres
sure relief valve i n the cap when the en
gine becomes hot .
- If, in an emergency, only water can be
added, the correct ratio between wate r
and antifreeze ~
page 220 must be re
stored as soon as possib le.
@) For the sake of the environment
Dra ined 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 .
An auxilia ry electric r adiator fan switches on
and off depending on coolan t tempera ture
and other vehicle operat ing condit ions .
After you switch the engine off, the aux iliary
fan can continue running for up to 10 minutes
- even w ith the ignition off . It can even swi tch
on aga in later by itself
c> .&. , if
- the temperature of the engine coo lant rises
due to the heat build-up from the engine in
the engine compartmen t, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
.&_ WARNING ,_
- To reduce the risk of personal injury nev
er touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can sw itch on suddenly
even when the engine is not running .
- The auxiliary radiator fan sw itches on au
tomatically when the engine coo lant
reac hes a certain t emperature and wi ll
continue to run until the coolant temper
a ture drops.

-Turn the valv e stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve.
- The tire pressures should only be checked
and adjus ted when the tires are cold . The
s li ght ly raised p ressures of warm tires must
not be reduced .
- Adjust the tire pressure to the load you are
carrying .
- Re insta ll the va lve stem cap on the valve.
When should I che ck the tire pres sur e?
The correct tire pressure is espec ially impor
tant at high speeds. The pressure should
therefo re be checked at least once a month
and a lways before start ing a journey.
When should I adjust the tire p re ssure s?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
o r replacing
wheels you have to adjust the tire pressures
on all wheels. In addition , you must then
store the new ti re pressu res in the t ire pres
sure monitoring system
r::!.> page 246 .
A WARNING
Incorrect tire pressures and/or underinf la
tion can lead sudden tire failure, loss of contro l, collision, serious persona l injury
or even death.
- When the warning symbo l
[ti] appears in
the instrument cl uster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla
t ion can cause increased tire wear and
can affect the handling of the veh icle and
stopp ing ability .
- Incorrect tire pressures and/or underin
flation can also lead to sudden tire fa il
ure, including a blowout and sudden de
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tir e pressures fo r all t ires on the vehicle .
T he applicable pressu re va lues are locat
ed on a stic ker on the drive r's side B-pil
lar .
- Only when a ll t ires on the vehicle are fi l
led to t he cor rect pressure, the ti re p res-
Tire s an d wheel s 235
sure monitor ing system can work cor
rectly.
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re p ress ure monito r
ing system .
- Always inf late t ires to the recommended
a nd correct t ire p ress ure before dr iv ing
off.
- Driving with unde rinflated tires bend
mo re, lett ing t hem get too hot resulti ng
in tread separation, s udden tire failure
and loss of cont ro l.
- Excess ive speed and/overloadi ng can
cause heat b uild- up, sudden tire failure
a nd loss of cont rol.
- If the tire pressure is too low or too high,
the t ires will wear prema turely and the
veh icle w ill not handle well.
- If the tire is not fla t and you do not have
to ch ange a wheel immedia tely, drive a t
red uced speed to the nearest service sta
tion to check the t ire p ress ure and add
air as requi red.
(D Note
Dr iving w it h out valve stem c aps can c ause
damage to the tire valves . To prevent this,
a lways make sure that factory insta lled
va lve stem caps on all whee ls are sec urely
mounted on the valve .
@ For the sake of the env ironment
Un derinflated tires wi ll also increase the
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any tire can carry.
A vehicle that is overloaded will not handle
well and is mo re d iff icult to stop. Overloading
can not o nly lead to loss of vehicle control,
but can also damage important parts of the
vehicle and c an le ad to sudden tire fa ilu re, .,..
