Technical Data
Starting-off and Driving– Depress the brake pedal fully and keep it depressed.
– Press the Shiftlock button (button in ha ndle of the selector lever), move the
selector lever into the desired position, e.g. in D, and then release the Shiftlock
button.
– Release the brake pedal and depress the accelerator .Stop– The selector lever position N does not have to be selected when stopping just for
a short time, such as at a cross roads. It is absolutely sufficient to hold the stopped
vehicle stationary by depressing the foot brake. The engine can, however, be
allowed just to idle.Parking– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector lever to P and
then release the Shiftlock button.
The engine can only be started when the selector le ver is in position P or N
 page 108. At temperatures below -10 °C the engine can only be started in the
selector lever position P .
It is sufficient to engage selector lever position P when parking on a flat surface. When
parking on a slope you should first apply the handbrake firmly and then move the
selector lever into position P. This is to ensure that there is no excessive pressure acting
on the lock mechanism and that it is easier to subsequently move the selector lever out
of position P.
If the selector lever position N is selected by accident while driving it is first necessary
to release pressure on the accelerator pedal and wait for idling speed of the engine to
be reached before engaging a drive position in the selector lever.
WARNING

Do not depress the accelerator when changing the position of the selector
lever if the car is stationary and the engine is running - risk of accident!

Never move the selector lever into position R or P when driving - risk of an
accident!

If you are stopping at a hill (downhill section), never try to hold the car
stationary with the gear engaged by mean s of the “accelerator”, this means by
letting the clutch slip. This can lead to ov erheating of the clutch. If there is a risk
of overheating of the clutch due to overlo ad, the clutch is opened automatically
and the vehicle rolls backward - risk of accident!

If yo u m us t s to p a t a sl ope , d e pre s s a nd ho ld t he b ra ke pe d a l , s o t ha t y ou c a n
prevent the vehicle from rolling back.Caution

The double clutch on the automatic gear box DSG is equipped with an overload
protection. If you make use of the uphill func tion on a vehicle which is stationary or
driving slowly uphill, it will result in an increase of thermal stress of the clutches.

An overheating of the clutches can be detect ed by the flashing of the selector level
indicator and the “jerk” of the clutches, finally the clutches are opened. The power
transmission from the engine to the front whee ls is interrupted and as a result of this
the vehicle can no longer be driven. If th e clutch opens automatically, depress the
brake pedal, wait a few seconds and only then continue driving.

offered must not tempt you to take greater risks than otherwise - risk of an acci-
dent!
Note

All four wheels must be fitted with the same tyres in order to achieve problem-free
operation of the ESP. Differing rolling circum ferences of the tyres can lead to an unde-
sirable reduction in the engine output.

Changes to vehicle (e.g. on engine, on th e brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the ESP page 214, “Accesso-
ries, changes and replacement of parts”.
Electronic Differential Lock (EDL and XDL)*
The electronic differential lock prev ents an individual wheel from slip-
ping.Models fitted with ESP ar e equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The EDL is activated automaticall y, that is without any action on the part of the driver.
It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should
only one drive wheel begin spinning on a slippery surface there will be an appreciable
difference in the speed of the driven wheels. The EDL function brakes the slipping
wheel and the differential transmits a greate r driving force to the other driven wheel.
This control process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatica lly if unusually severe stresses exist in order to avoid
excessive heat generation in the disc brake on the wheel which is being braked. The
vehicle can continue to be driven and has the same characteristics as a vehicle not
fitted with EDL. The EDL switches on again automatically
as soon as the brake has cooled down.
XDL function (only for Octavia RS)
The XDL function is an extension to the electronic differential lock. The XDL function
does not respond to traction, but to the relief of the inner front wheel during fast
cornering. An active brake intervention on the brake of the inner wheel prevents it from
spinning. Thus, the trac tion is improved and the vehicle continues to follow the desired
track.
WARNING

Carefully depress the accelerator when accelerating on uniformly slippery
road surfaces, such as ice and snow. Th e driven wheels might still spin despite
the EDL and affect the stability of the vehicle - risk of an accident!

You should always adapt your style of driving to the condition of road
surface and to the traffic situation even when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than
otherwise - risk of an accident!Note

If the ABS or ESP warning light comes on, this may also indicate a fault in the EDL.
Please have the vehicle inspected as soon as possible by a specialist garage.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the EDL page 214, “Accesso-
ries, changes and replacement of parts”.

Technical Data
Headlights
Before starting off with a hitched trailer, also check the setting of the headlights. Alter
the setting as necessary with the ai
d of the headlight beam adjuster page 56.
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 184.
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 16, “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 201,
“Inspecting the coolant level”.
Please refer to the following guidelines  page 31, “Coolant temperature/coolant
level ”.
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.

RefuellingFig. 159 Right rear side of the vehicle: Open fuel filler flap / fuel filler flap with cap unscrewedThe filler flap is automatically unlocked or locked* with the central locking.Opening the fuel filler cap– Press in the middle of the left area of the fuel filler flap in direction of arrow
 fig. 159 .
– The fuel filler cap on the fuel filler tube must be unlocked to the left using the
vehicle key (only valid for vehicles which do not have automatic unlocking of the
fuel filler flap).
– Unscrew the fuel filler cap anti-clockwise and place the fuel filler cap from above
on the fuel filler flap fig. 159 - right.Closing fuel filler cap– Screw on the fuel filler cap by turning it to the right until it is heard to click.
– The fuel filler cap on the fuel filler tube mu st be locked to the right using the vehicle
key (only valid for vehicles which do not ha ve 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 192. The fuel tank has a capacity of about 55°litres or 60 litres
17).
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.

Make sure that the valve is not pressed into the filler tube when inserting the pump
nozzle into the filler tube. Otherwise you ar e unintentionally filling up the volume,
which in case of heat can cause an expansion of the fuel. This can lead to an overflow
of fuel or damage to parts of the fuel reservoir.

The fuel tank is full just as soon as the pump nozzle switches off for the first time,
provided the nozzle has been operated properly. Do not continue refuelling - other-
wise the expansion volume is filled up.

Technical Data
Note
On vehicles which are fitted with an indepe ndent auxiliary heating and ventilation, the
volume of the coolant is greater by approx. 1 ltr.Inspecting the coolant levelThe coolant expansion bottle is located in the engine compartment on the right.
– Switch the engine off.
– Open the bonnet page 196.
– Check the level of coolant in the coolant expansion bottle fig. 164 . The coolant
level when the engine is cold must lie between the (MIN) and (MAX) mark-
ings. The level may also rise slightly above the (MAX) marking when the engine
is warm.
If the coolant level in the reservoir is too lo w, this is indicated by the warning light in
the instrument cluster page 31, “Coolant temperature/coolant level ”. We never-
theless recommend inspecting the coolant leve l 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. You should
not merely top up the coolant in the reservoir. It is also important to have the cooling
system inspected without delay by a specialist garage. Losses can only occur through the pressure
relief in the cap of the coolant expansion
bottle which is completely free of leaks if the coolant boils as a result of overheating
and is forced out of the cooling system.
WARNING
Read and observe the warning notes page 197, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as s oon as possible if the source of overheating
itself cannot be determined and removed, since there may be grave damage to the
engine.Replenishing the coolant– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir fig. 164 and
unscrew the cap carefully by turning it to the left .
–Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing th e system, must comply with one specific
specification page 200. Do not use an alternative additive if the coolant additive
G13 is not available in exceptional cases. Just top up the system with water and as soon
as possible arrange adjustment to correct the mixing ratio of water and coolant addi-
tive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill up over the “MAX” marking! Excess coolant which is heated up is forced out
of the cooling system through the pressure relief valve in the cap of the coolant
compensation bottle.
Wait until the engine has cooled down for a system which has suffered a major loss of
coolant before pouring in coolant. This is necessary to avoid engine damage.
