– Drive at walking speed over rocky passages. – If it is not possible to drive around a ston
e, gently drive onto
the stone with one of
the front wheels and then drive over it slowly.
WARNING
Observe the important guidelines
⇒page 180.
Caution
•
On no account drive over large objects (suc
h as pieces of rock
or tree stumps),
neither in the middle nor on one side. When driving over objects which are larger than the ground clearance, the chassis and its
components can get da
maged. Your vehicle
could break down far away from any assistance.•
Even objects that are smaller than the ex
isting ground clearance can come into
contact with the underbody of the vehicle an
d can lead to damage or failure of the
vehicle. This applies especially when there is
a hollow or soft ground in front or behind
the object or if you drive too fast over th
e object and thus the vehicle is deflected.
For the sake of the environment
Leaking engine oil and brake fluid pollute the environment and contaminate the bodies of water. The dispos
al e.g. of engine oil soaked soil can be costly.
Crossing bodies of waterParticular attention is required wh
en driving through bodies of water
⇒page 179.
Driving through snow-covered terrain– Before you drive through snow-covered te
rrain, mount snow chains on the front
wheels or on the rear wheels
⇒page 219, “Snow chains” in order to achieve the
best possible traction.
–Switch on the Off-road mode
⇒page 170.
Even harmless looking sections of terrain can be dangerous. This applies in particular for sections where no ruts or other tracks are visible.
WARNING
•
Driving through snow-covered terrain poses special dangers. Never choose
a dangerous route and never take a risk which could jeopardize your safety and that of your passengers. If you cannot go on or if you doubt the safety of the route, turn back and choose another way.•
Potholes, troughs, trenches, precipices,
sheets of ice or other obstructions
are often completely or partially obscured by snow.•
The hidden dangers of snow can cause an accident, serious injuries or your
vehicle to break down under
extreme weather conditions.
Driving over steep terrainDriving uphill and downhill– Stop the vehicle before driving uphill or
downhill, exit the vehicle and explore the
situation.
– Walk a stretch and check the firmness of the soil and look for obstructions or other
hidden dangers.
– Check how the route continues beyond the slope. – Switch on the Off-road mode
⇒page 170.
– Drive slowly and steadily straight uphill or downhill.– Do not stop the vehicle on a hillside or attempt to turn around. – You must prevent the engine from cutting out.Driving uphill– Check before driving over a hilltop, how it
continues on the other side. If you drive
up a steep hill, the vehicle faces the sky and you cannot see what is directly in front of the vehicle.
– Switch on the Off-road mode

– Do not shift gears or release the
clutch during th
e climbing phase.
– Depress the accelerator only as much as
is necessary in order
to handle the slope.
If you can go no further on a slope– Never attempt to make a turn with the vehicle on a hillside. – If the engine cuts out, press the foot brake and restart the engine. – Engage the reverse gear and carefully
drive backwards in your own tracks.
– Press the foot brake in order to maintain a constant speed.Driving downhill–Switch on the Off-road mode
⇒page 170.
– Shift into first gear or select the first driving stage, while in the Tiptronic mode, to
drive downhill on steep hillsides in order
to use the Downhill Drive Support to its
maximum.
– Press the foot brake gently, so you do not lose the control over your vehicle. – If it is feasible and safe, drive straight down (maximum gradient).– Do not release the clutch or shift into Neutral.
WARNING
•
Never attempt to drive uphill or downhill if it is too steep for your vehicle.
The vehicle could slip or roll
over - risk of accident!
•
Never attempt to make a turn on a hillside. The vehicle could tilt or roll over.
This can result in serious accidents.•
If the engine cuts out on a slope or
you can no longer go on for whatever
other reason, then stop!•
Never let the vehicle roll down the hill
side at idling speed. You can lose the
control over your vehicle.•
If the engine cuts out, press the foot brake and restart the engine. Engage the
reverse gear and carefully drive backward
s in your own tracks. Use the engine
braking power and press the foot brake in order to maintain a slow and constant speed.

Driving at an angle on a hillsideFig. 166 Steer and maintain your trajectory
/ in direction to exit - facing uphill
Driving at an angle on a hillside is one of the most dangerous situations while driving off-road. It may look harmle
ss, but you must never underestimate the difficulties and
the dangers when driving at an angle on a
hillside. Basically you should avoid moving
your vehicle into a sideways
position on a hillside. Unde
r certain circumstances, the
vehicle can slide away uncontrollably or roll over. Check before driving in a tilted position, whether there is a different and safer route. If you have to drive in a tilted position, then
the ground should be as firm and even as
possible. Note that the vehicle may slide sideways or sink in and roll over when driving on slippery or soft ground. Make sure that
the inclination is not too steep when driving
over surface irregularities. Otherwise, the vehicle can roll over and then roll down the hillside. If the vehicle is at a very steep angle, the wheels on the low side must not sink deeply into the ground or into troughs and you mu
st not drive over stones, tree stumps or
other obstructions with the alternate raised wheels. If there is a risk your ve
hicle may tilt, steer immedi
ately in direction of dip

foreign bodies from the tyre tread.
– Clean the turn signal lights, the headlights, the number plate and the windows. – Check the underbody of the vehicle and re
move trapped objects, such as scrub or
wood pieces.
– Contact your specialist gara
ge if you detect any damage.
– In case of thick layers of
dirt, clean the radiator grille, the engine compartment and
the underbody of the vehicle.
WARNING
•
Combustible materials which are trapped under the vehicle floor can be
dangerous. They can impair the driving
safety and the safety of all the occu-
pants of the vehicle. After driving off-
road, always check the underside of the
vehicle and remove trapped objects.•
Never continue the journey if objects
are trapped under the vehicle. This
can damage the fuel lines, the brake sy
stem, the seals and other parts of the
chassis.•
Combustible objects such as dry leaves or twigs could ignite on hot vehicle
parts. A vehicle fire can also lead to serious injuries.•

Detachable ball head The ball rod is detachable on vehicles which
feature a factory-fitted
towing device. It is
stowed together with separate fitting instru
ctions in the spare wheel well in the luggage
compartment of the vehicle. Further information on the towing device
⇒page 192.
Note
•
We recommend that you also have your
vehicle inspected between service inter-
vals if you tow a trailer frequently.•
The handbrake on the towing vehicle must be put on when coupling and decou-
pling the trailer.Driving Tips Particular caution is required when towing a trailer.– Do not, as far as possible, drive with
your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to
downhill sections.
– Apply the brakes in good time. – Keep a check on the coolant temperature gauge if the outside temperature is high. Distribution of weight The distribution of the weight
is very poor if your vehicle
is unladen and the trailer is
laden. Maintain a particularly low speed if you cannot avoid driving with this combina-tion. Driving speed Do not drive faster than 80 km/hour for safety reasons. This also applies for countries in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with increasing speed means that the legally allowed speed should not be used when there are unfavourable road, weather or wind cond
itions, particularly near accident black
spots. You must always reduce your speed immediat
ely as soon as you detect even just the
slightest swaying
of the trailer. On no account attempt to stop the trailer from
“swaying” by accelerating. Apply the brakes in good time! If
the trailer is fitted with a
trailer brake
, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting from the trailer wheels locking. Shift down gears in good time before negotiating a downhill section to allow the engine to also act as a brake. Engine overheating Please keep a check on the coolant temperature gauge if you have to negotiate a lengthy slope in a low gear at a high engi
ne speed when the outside temperature is
very high
⇒page 17, “Coolant temperature gauge”.
If the needle of the coolant temperature gauge moves into the right-hand area or even the red area of the scale, reduce your speed immediately. Stop and switch off the engine if the warning light
 in the instrument cluster begins flashing. Wait a few
minutes and check the level of coolant in the coolant expansion bottle
⇒page 207,
“Inspecting the coolant level”. Please refer to the following guidelines
⇒page 34, “Coolant temperature/ Coolant
quantity
”.
The coolant temperature can be reduced by switching on the heating.Any increase in the cooling effect of the coolant fan through shifting down a gear and increasing the engine speed is not possible
since the fan speed is independent of the
engine speed. One should also not drop a gear
for this reason when towing a trailer as
long as the engine can manage th
e slope without any drop in speed.

Technical Data
Underbody protectionThe underside of your vehicle is protected for life against chemical and mechanical influences. One cannot, however, complete
ly rule out damage to the
protective layer
when
driving so we recommend that you inspect the protective layer on the underside of your vehicle and on the
chassis at certain intervals - this is best done at the beginning
and end of the winter - and to touch up any damaged areas. The authorised Škoda Service Partners have suitable
spray products
available as well
as the necessary equipment and are familiar with the instructions for use. It is therefore best to have such touch-up
work or additional corrosion
protection measures carried
out by an authorised Škoda Service Partner.
WARNING
Never use additional underbody protection or corrosion-protection agents for the exhaust pipes, catalytic converters, di
esel particle filter or heat shields.
When the engine reaches its operating
temperature, these substances might
ignite - risk of fire!Protection of hollow spacesAll the cavities of your vehicle which are at risk from corrosion are protected for life by a layer of
protective wax
applied in the factory.
This wax protection does not require to be inspected or re-treated. Please remove any small amount of wax which flows out of the cavities at high temperatures with a plastic scraper and clean the spot using petroleum cleaner.
WARNING
Safety and environmental pr
otection regulations should observed when using
petroleum cleaner to remove wax - a risk of fire!
Engine compartmentGood corrosion protection is very importan
t, particularly in winter when one often
drives over its salt-strewn roads. One should therefore clean the whole engine compartment before and after the salt spread
ing period and treat with preservative in
order to prevent the salt from being destructive. The authorised Škoda Service Partners have the cleaning agents and preservatives recommended by the manufacturer and also the required equipment.
WARNING
•
It is necessary to observ
e the guidelines given in the chapter before working
on the engine compartment
⇒page 204, “Working in the engine compart-
ment”.•
Let the engine cool down before cleaning the engine compartment.Caution
•
Engine cleaning may be only be un
dertaken when the ignition is off.
•
It is recommended to cover the generator before washing the engine compart-
ment.
For the sake of the environment
The dirty water produced by washing the engine has washed away petrol, and residues of grease and oil and should therefore be
cleaned by an oil separator. This is why
engine washing should only be undertaken in
a specialist garage or at a fueling station
(when these are fitted with the required equipment).Care of the interior of vehiclePlastic parts, artificial leather and clothsYou can clean plastic parts and artificial le
ather with a moist cloth. You should only
treat such parts with special
solvent-free plastic cleaning and care products
it does
prove to be adequate.

Fuel
200
FuelPetrolGrades of petrolThere are various grades of petrol. Please read
⇒page 243, “Technical Data” in order
to know which grade of petrol your vehicle
requires. You will also find the same infor-
mation affixed to the inside of th
e fuel filler flap of your vehicle
⇒page 201, fig. 168
.
A distinction is made between unleaded and
leaded petrol. All Škoda vehicles with
petrol engines are equipped wi
th a catalytic converter and must therefore be only
driven with
unleaded petrol
. Unleaded petrol complies with the
standard EN 228
.
The individual grades of petr
ol are distinguished by their
octane number
(RON).
Please adopt the following procedure if the grade of petrol which you normally use is not be available in exceptional circumstances. Engines which need
unleaded premium petrol 95 RON
can also be run on unleaded
regular petrol 91 RON. This does, however,
result in a slight loss in performance.
If, in an emergency, the only fuel availa
ble is one which has a lower octane number
than that required by the engine then only drive at medium engine speeds and lower engine loadings. You can make unlimited use of fuel whic
h has a higher octane number than that
required by the engine. There will, however, be no advantages gained by this in terms of engine performance and fuel consumption! The handling, performance and life of your
engine are determined to a significant
extent by the quality of the fuel. Do not use any petrol additives.
Use fuel which
complies with the standard EN 228
.
You can find further information on refuelling
⇒page 201, “Refuelling”.
Caution
•
Filling the tank even only once with le
aded petrol will resu
lt in the catalytic
converter being destroyed.•
Operating the engine with petrol of a low octane number can result in engine
damage at high revolutions or severe engine loading.
DieselDiesel fuelYour vehicle can be operated with
diesel fuel
, which complies with the standard
EN 590
.
Fuel additives You must not use fuel additives, so-called “flow improvers” (petrol and similar prod- ucts) in diesel fuel. If the quality of the diesel fuel is poor, it is then necessary to drain the
fuel filter
more
often than stated in the Service schedule. You can find information on refuelling
⇒page 201, “Refuelling”.
Caution
•
Only use fuel which complies with the standard
EN 590
. Filling the tank even only
once, which does not comply with the stan
dard, can result in damage to the fuel
system.•
Water which has collected in the fuel filter can result in engine problems.
•
Your vehicle is not adapted for use of biodie
sel, therefore this fuel must not be refu-
elled and driven. Using this biodiesel can lead to damage to the engine or the fuel system.Operation in winterWinter-grade diesel fuel A different grade of diesel fuel is available at filling stations in winter than during the summer. Using “summer-grade diesel fuel” at temperatures below 0°C can result in operational problems because the diesel beco
mes viscous as a result of paraffin sepa-
ration.

It is therefore the case that EN 590 prescribes diesel fuel class for certain periods of the year which can also be purchased at the co
rresponding time during the year. “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 avail- able have a different temperature characte
ristic. The authorised Škoda Service Part-
ners and filling stations in the country concer
ned will be able to provide you with infor-
mation regarding the diesel fuels available. Prewarming fuel The vehicle is fitted with a fuel filter prewarming system. This secures operation of a vehicle using diesel fuel down to an environmental temperature of -25°C.
Caution
It is not permitted to add the various fuel
additives on the market, including petrol, to
diesel fuel in order to im
prove its flow properties.

Closing fuel filler cap– Screw on the cap by turning it to the right until it is heard to lock. – The fuel filler cap on the fuel filler tube
must be locked to the right using the vehicle
key (only valid for vehicles which do not
have automatic locking of the fuel filler
flap).
– Close the fuel filler flap until it locks. The correct grade of fuel for your vehicle as well as the tyre size and inflation pressures are stated on a sticker affixed to the inside of the fuel filler flap. Further information on fuel
⇒page 200.
The fuel tank has a capacity of about 60 litres.
WARNING
Pay attention to any legal requirements if
you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for safety reasons. The canister can be damaged
in the event of an accident and fuel
may leak out.
Caution
•
Before refuelling it is necessary to switch off the auxiliary heating system (auxiliary
heating and ventilation) *.•
Remove any fuel which has spilled onto th
e paintwork of your vehicle immediately
- risk of paint damage!•
On vehicles fitted with a ca
talytic converter, never let the fuel tank run completely
empty. An irregular supply of fuel to the engine can result in misfiring and unburnt fuel may get into the exhaust system, which may result in overheating and damage to the catalytic converter.
