2012 SKODA YETI engine coolant

Immediately reduce your speed as soon as even the slightest swaying of the trail-
er is detected. Never attempt to stop the trailer from “swaying” by accelerating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first, then brake firmly. This will avoid brake jolts resulting from
the trailer wheels locking. On downhill sections shift down a gear in good time to
also use the engine as a brake.
Trailer stabilisation
The trailer stabilisation is an extension of the stabilisation control that works in
conjunction with the counter-steering assistance to reduce the amount the trail-
er "sways". After turning on the ignition, the ESC indicator light  in the instru-
ment cluster lights up for about 2 seconds longer than the ABS indicator light.
Prerequisites for stabilising the trailer.
› The towing device is factory-fitted or a compatible towing device has been ret-
rofitted.
› The ESC is active. The indicator light
 or  in the instrument cluster is not illu-
minated.
› The trailer is electrically connected to the towing vehicle by means of the trailer
socket.
› The speed is higher than approx. 60 km/h.
› Trailers must have a fixed drawbar.
› The ESC works for both braked and unbraked trailers.
Trailer is connected to the anti-theft alarm system. › If the vehicle is factory-fitted with an anti-theft alarm system and a towing de-
vice.
› If the trailer is electrically connected to the towing vehicle by means of the trail-
er socket.
› If the electrical system of the vehicle and trailer is fully functional.
› If the vehicle is locked with the car key and the anti-theft alarm system is acti-
vated.
When the vehicle is locked, the alarm is activated as soon as the electrical con-
nection to the trailer is interrupted.
Always deactivate the anti-theft alarm system before a trailer is connected/dis-
connected. Otherwise, the anti-theft alarm system could accidentally be trig-
gered » page 31 , Anti-theft alarm system . Engine overheating
If the needle for the coolant temperature gauge moves into the right-hand area
or the red area of the scale, the speed must be reduced immediately. Stop and
switch off the engine if the indicator light
 in the instrument cluster starts to
flash. Wait a few minutes and check the level of coolant in the coolant expansion
bottle » page 174, Checking the coolant level .
The following guidelines must be observed » page 20, Coolant temperature/cool-
ant level  .
The coolant temperature can be reduced by switching on the heating. WARNING
■ The increased safety offered by the trailer stabilisation must not tempt you
to take greater risks than otherwise. ■ Adapt your speed to the conditions of the road surface and to the traffic sit-
uation.
■ Improper or incorrectly connected electric cables can energise the trailer and
cause functional faults to the vehicle's entire electrical system as well as acci-
dents and severe injuries.
■ Any work on the electrical system must be carried out only by ŠKODA spe-
cialist garages.
■ Never directly connect the trailer's electrical system with the electrical con-
nections for the tail lights or other current sources. CAUTION
■ The trailer stabilisation need not be able to correctly detect all of driving situa-
tions.
■ Trailers that sway slightly are not always detected by the trailer stabilisation
and thus are not stabilised accordingly.
■ Release the pressure on the accelerator pedal if the system is being regulated.
■ Avoid abrupt and sudden driving/braking manoeuvres.
■ When the ball rod is removed, the mounting shaft must be sealed with an ap-
propriate cover. This prevents foreign matter from penetrating into the mounting
shaft. See the fitting instructions for the towing device. £
158 Driving Tips

Diesel fuel
First read and observe the introductory information and safety warn-
ings on page 167.
Your vehicle can only be operated with
diesel fuel, which complies with the
standard EN
590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in
Austria, GOST R 52368-2005/EN 590:2004 in Russia).
Operation in winter - Winter-grade diesel fuel
In the winter, only use diesel fuel, which complies with the standard EN 590
(standard DIN 51628 in Germany, standard ÖNORM C 1590 in Austria,
GOST R 52368-2005/EN 590:2004 in Russia). “Winter-grade diesel fuel” will still
operate properly even at a temperature of -20 °C.
It is often the case in countries with different climatic conditions that diesel fuels
available have a different temperature characteristic. The ŠKODA Service Partners
and filling stations in the relevant country will be able to provide you with infor-
mation regarding the diesel fuels available.
Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures operation of
a vehicle using diesel fuel down to an environmental temperature of -25 °C.
Fuel additives
Fuel additives, so-called “flow improvers” (petrol and similar products) must not
be added to the diesel fuel. CAUTION
■ Just filling the tank once with diesel fuel that does not comply with the stand-
ard, can cause severe damage to parts of the engine, the fuel and exhaust sys-
tem!
■ If a different fuel other than diesel fuel, which complies to the above mentioned
standards (e.g. petrol) is used by mistake do not start the engine or switch on the
ignition! Extensive damage to engine parts can occur! We recommend that the
fuel system is cleaned by a

ŠKODA Service Partner.
■ Water which has collected in the fuel filter can cause engine faults.
■ Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must not
be refuelled and driven. The use of biofuel (RME) can cause considerable damage
to parts of the engine or fuel system. Ð

There is a risk of injuries, scalding, accidents and fire when working in the en-
gine compartment, e.g. inspecting and replenishing oil and other fluids. For this
reason, it is essential to comply with the warning instructions stated below and
with the general applicable rules of safety. The vehicle's engine compartment is
a hazardous area . WARNING
■ Never open the bonnet if you can see steam or coolant flowing out of the
engine compartment - risk of scalding! Wait until the steam or coolant has
stopped escaping.
■ Turn off the engine and withdraw the ignition key.
■ If the vehicle is fitted with a manual gearbox, move the gearshift lever into
Neutral, or if the vehicle is fitted with an automatic gearbox, move the selec-
tor lever into position P .
■ Firmly apply the handbrake.
■ Allow the engine to cool.
■ For safety reasons, the bonnet must always be properly closed when driving.
This is why after closing the bonnet, the lock must always be checked to en-
sure it has engaged properly. £

Inspecting and replenishing

WARNING (Continued)
■ If you notice that the lock is not properly engaged while driving, stop the ve-
hicle immediately and close the bonnet - risk of an accident!
■ Keep children clear of the engine compartment.
■ Do not touch any hot engine parts - risk of burns!
■ Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite!
■ Avoid short circuits in the electrical system - particularly on the vehicle's
battery.
■ Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running! ■ Never open the end cover of the coolant expansion reservoir while the en-
gine is still warm. The cooling system is pressurized!
■ When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot cool-
ant.
■ Do not leave any items such as cloths or tools in the engine compartment.
■ If you wish to work under the vehicle, you must secure the vehicle from roll-
ing away and support it with suitable supporting blocks: the car jack is not
sufficient for this - risk of injury!
■ If any inspection work has to be carried out when the engine is running,
there is an additional risk from rotating parts (e.g. V-belt, alternator, radiator
fan) and the high-voltage ignition system. The following must also be ob-
served. ■Never touch the electric wiring on the ignition system.
■ Always make sure that no jewellery, loose clothing or long hair can get
caught in rotating engine parts - hazard! Always remove any jewellery, tie
back long hair and wear tight fitting clothing before completing any work.
■ Additionally, the following warning instructions must be observed if work
has to be carried out on the fuel or electrical system. ■Always disconnect the vehicle battery from the electrical system.
■ Do not smoke.
■ Never work near open flames.
■ Always have a functioning fire extinguisher nearby. CAUTION
■ Always top up using the correct specification of fluids. This may result in major
operating problems and also vehicle damage!
■ Never open the bonnet using the locking lever - danger of causing damage. For the sake of the environment
In view of the environmentally friendly disposal of fluids, the specials tools and
knowledge required for such work, we recommend that fluids are changed by a
Škoda
Service Partner as part of the inspection service. Note
■ If you have any questions regarding the fluids, visit a
ŠKODA Service Partner.
■ Fluids with the correct specifications can be purchased from ŠKODA Original Ac-
cessories. Ð

Changing engine oil
First read and observe the introductory information and safety warn-
ings on page 169.
The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator
» page 10, Service Interval Display.CAUTION
Additives must not be added to the engine oil - risk of causing considerable dam-
age to parts of the engine! Damage, which results from such product, are exclu-
ded from the warranty. Note
If your skin has come into contact with oil, it must be washed thoroughly. ÐCoolant
First read and observe the introductory information and safety warn-
ings on page 169.
The cooling system is filled with a coolant in the factory.
The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture provides antifreeze protection down to -25
°C and also protects the
cooling and heating system from corrosion. It also prevents the formation of scale
and significantly increases the boiling point of the coolant.
The concentration of coolant must therefore not be reduced by adding water dur-
ing the summer months or in countries with a warm climate. The concentration of
coolant additive in the coolant must be at least 40 %. 40 %.
If a higher concentration of antifreeze is required for climatic reasons, the amount
of coolant additive can only be increased up to 60 % (antifreeze protection down
to approx. -40 °C). The antifreeze protection tails off above that concentration.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries the concentration of coolant additive should be at least 50 %.
When refilling, we only recommend you use the same antifreeze written on the
antifreeze expansion tank » Fig. 143 on page 174.

■ Other coolant additives that do not comply with the correct specifications can
above all significantly reduce the anticorrosion effect.
■ Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage! Note
On vehicles that are fitted with an auxiliary heater (auxiliary heating and ventila-
tion), the coolant capacity is approx. 1 l larger. Ð

Inspecting and replenishing

Checking the coolant level
Fig. 143
Engine compartment: Coolant
expansion reservoir
First read and observe the introductory information and safety warn-
ings on page 169.
The coolant expansion bottle is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 171.
› Check the level of coolant in the coolant expansion bottle
» Fig. 143. The cool-
ant level when the engine is cold must lie between the B
(MIN) and A
(MAX)
markings. The level may also rise slightly above the A
(MAX) marking when the
engine is warm.
If the coolant level in the coolant expansion tank is too low, this is indicated by
the indicator light  lighting up in the instrument cluster » page 20, Coolant tem-
perature/coolant level . We still recommend inspecting the coolant level directly
at the reservoir from time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a
ŠKODA spe-
cialist garage immediately. CAUTION
If a fault causes the engine to overheat, we recommend visiting a ŠKODA Service
Partner immediately, otherwise serious engine damage may occur. Ð
ä Replenishing the coolant
First read and observe the introductory information and safety warn-
ings on page 169.
›
Switch off the engine.
› Allow the engine to cool.
› Place a cloth over the cap of the coolant expansion reservoir
» Fig. 143 on
page 174 and unscrew the cap carefully.
› Replenish the coolant.
› Turn the cap until it clicks into place.
Do not use an alternative additive if the specified coolant is not available in an
emergency. In this case, just use water and have the correct mixing ratio of water
and the coolant additive restored by a ŠKODA

specialist garage as soon as possi-
ble.
Only use new coolant to top up the system.
Do not fill the coolant above the mark A
(max.)
» Fig. 143 on page 174! Excess
coolant heats up and then is forced out of the cooling system through the pres-
sure relief valve in the cap. WARNING
■ The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to health.
Therefore always safely store the coolant additive in its original container out
of the reach of children - risk of poisoning!
■ If any coolant splashes into your eyes, immediately rinse out your eyes with
clear water and contact a doctor as soon as possible.
■ You should also consult a doctor without delay if you have inadvertently
swallowed coolant. CAUTION
Do not continue your journey, if it is not possible  to top up the coolant under
the prevailing conditions . Contact a

ŠKODA Service Partner to avoid the risk of
serious engine. Ð

174 General Maintenance

Radiator fan
First read and observe the introductory information and safety warn-
ings on page 169.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
After switching off the ignition, the radiator fan can intermittently continue to op-
erate for approx. 10 minutes.
ÐChecking the brake fluid
Fig. 144
Engine compartment: Brake fluid
reservoir
First read and observe the introductory information and safety warn-
ings on page 169.
The brake fluid reservoir is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 171.
› Check the level of brake fluid in the reservoir
» Fig. 144. The level must be be-
tween the “MIN” and “MAX” markings.
When driving, a slight drop in the fluid level is caused by the wear-and-tear and
automatic adjustment of the brake pads, and is therefore perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid lev-
el drops significantly within a short time or if it drops below the “MIN” marking. If
the brake fluid level is too low, this is indicated by the indicator light  lighting
up in the instrument cluster » page 19, Brake system .
ä
ä WARNING
If the fluid level has dropped below the MIN marking,  do not continue your
journey - risk of accident! Seek help from a
ŠKODA specialist garage.Ð Changing the brake fluid
First read and observe the introductory information and safety warn-
ings on page 169.
Brake fluid absorbs moisture. Over time it therefore absorbs moisture from the
environment. Excessive water in the brake fluid may be the cause of corrosion in
the brake system. The water content also lowers the boiling point of the brake
fluid.
The brake fluid must comply with the following standards or specifications:
› VW 50114;
› FMVSS 116 DOT4. WARNING
Using old brake fluid can result in severe stress on the brakes because of the
formation of vapour bubbles in the brake system. This greatly impairs the
braking efficiency and thus also the safety of your vehicle. CAUTION
Brake fluid damages the paintwork of the vehicle. Ð
