Engine oilEngine oil specifications
The engine oil used must conform with exact specifications.Specifications
The engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.
As the use of high quality oil is essential for the correct operation of the
engine and its long useful life, when topping up or replacement is necessary
use only those oils that conform to the requirements of the VW standards.
If it is not possible to find oil co nforming to the VW standards then oil
conforming to the ACEA or API standa rds with an appropriate viscosity at
atmospheric temperature should be used instead. The use of this type of oil
may have some repercussions on the performance of the engine for example,
long starting time, increased consumption and a higher emission level.
If a top up is required then different oils may be mixed as long as they all
conform to the VW standards.
The specifications (VW standards) set out in the following page should
appear on the container of the service oil; the container will display together
the different standards for petrol and diesel engines, the oil can be used for
both types of engines.

216Washer fluid and windscreen wiper bladesTopping up washer fluid
The water for cleaning the windscreen should always be
mixed with washer fluid.The windscreen washer and the headlight washing system are supplied with
fluid from the windscreen washer fluid container in the engine compartment.
The reservoir is located on the right-hand side of the engine compartment.
Plain water is not enough to clean th e windscreen and headlights. We recom-
mend that you always add a product to the windscreen washer fluid.
Approved windscreen cleaning products exist on the market with high deter-
gent and anti-freeze properties, thes e may be added all-year-round. Please
follow the dilution instructions on the packaging.
WARNING
Any work carried out in the engine compartment or on the engine must be
carried out cautiously.•
When working in the engine compartment, always observe the safety
warnings ⇒page 206.Caution
•
Never put radiator anti-freeze or other additives into the windscreen
washer fluid.
•
Always use approved windscreen cleansing products diluted as per
instructions. If you use other washer fluids or soap solutions, the tiny holes
in the fan-shaped nozzles could become blocked.

Checking and refilling levels
220However, if the level goes down noticeably in a short time, or drops below the
“MIN” mark, there may be a leak in the brake system. A display on the instru-
ment panel will warn you if the brake fluid level is too low ⇒page 72.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings ⇒page 206.Changing the brake fluid
The brake fluid must be renewed every two years.We recommend that you have the brake fluid changed by an Authorised
Service Centre.
Before opening the bonnet, please read and follow the warnings ⇒ in
“Safety instructions on working in the engine compartment” on page 206 in
“Working in the engine compartment”.
Brake fluid absorbs moisture. In the cour se of time, it will absorb water from
the ambient air. If the water content in the brake fluid is too high, the brake
system could corrode. This also considerably reduces the boiling point of the
brake fluid. Heavy use of the brakes may then cause a vapour lock which
could impair the braking effect.
For this reason the brake fluid must be renewed every two years.
It is important that you use only use brake fluid compliant with the US
standard FMVSS 116 DOT 4. We recommend the use of Genuine SEAT brake
fluid.
WARNING
Brake fluid is poisonous. Old brake fluid impairs the braking effect.
•
Before opening the bonnet to check the brake fluid level, read and
observe the warnings ⇒page 206.
•
Brake fluid should be stored in the closed original container in a safe
place out of reach of children. There is a toxic risk.
•
Have the brake fluid changed every two years at the latest. Heavy use
of the brakes may cause a vapour lock if the brake fluid is left in the system
for too long. This would seriously affect the efficiency of the brakes and the
safety of the vehicle. This may cause an accident.Caution
Brake fluid could damage the paintwork. Wipe off any brake fluid from the
paintwork immediately.
For the sake of the environment
Brake fluid must be drained and disposed of in the proper manner observing
environmental regulations.

BatteryWarnings on handling the battery
WARNING
Always be aware of the danger of injury and chemical burns as well as the
risk of accident or fire when working on the battery and the electrical
system:•
Wear eye protection. Protect your eyes , skin and clothing from acid and
particles containing lead.
•
Battery acid is very corrosive and caustic. Wear protective gloves and
eye protection. Do not tilt the batteries. This could spill acid through the
vents. Rinse battery acid from eyes immediately for several minutes with
clear water. Then seek medical care immediately. Neutralize any acid
splashes on the skin or clothing with a soapy solution, and rinse off with
plenty of water. If acid is swallowed by mistake, consult a doctor immedi-
ately.
•
Fires, sparks, naked lights and smoking are prohibited. When handling
cables and electrical equipment, avoid causing sparks and electrostatic charge. Never short the battery terminals. High-energy sparks can cause
injury.
•
A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.
•
Keep children away from acid and batteries.
•
Before working on the electrical system, you must switch off the
engine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only switch
off the light.
•
Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alar m will otherwise be triggered.
•
When disconnecting the battery from the vehicle electrical system,
disconnect first the negative ca ble and then the positive cable.
•
Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never
reverse the polarity of the connections. This could cause an electrical fire.
•
Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery that has
frozen. A flat battery can freeze at temperatures around 0
°C.
•
Ensure that the vent hose is always connected to the battery.
•
Never use a defective battery. This may be fatally explosive. Replace a
damaged battery immediately.Caution
•
Never disconnect the battery if the ignition is switched on or if the engine
is running. This could damage the electrical system or electronic compo-
nents.

Some of the electrical items listed in the table are only fitted on certain
models or are optional extras.
Please note that the above list, while correct at the time of printing, is subject
to alterations.Bulb changeGeneral notesBefore changing any bulb first turn off the equipment concerned.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a
reduction in the bulb life and condensation on the mirror surface, thus
reducing efficiency. A bulb should only be replaced by one of the same type. The type is inscribed
on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the bulbs that most affect road safety should have spares in the
vehicle.
