Fig. 184 On the instrument cluster display: the bonnet is open or has not been closed properly.
A symbol in the instrument cluster display ⇒ Fig. 184  indicates if the bonnet is open or is not closed
properly.
Do not drive on! If necessary, lift the bonnet and then close it again.
This symbol is also visible when the ignition is switched off and will go out a few seconds after the
vehicle has been locked when all doors are closed.

WARNING
Failure to observe warnings can cause your vehicle to break down in traffic, which can lead to
accidents and serious injuries.
ver ignore any warnings.


The symbol can differ depending on the version of the instrument cluster.
Service fluids and consumables
All service fluids and consumables, e.g. tyres, coolant and vehicle batteries, are being constantly
developed. The same applies to toothed belts, engine oils and spark plugs for combustion engines,
for example. For this reason, service fluids and consumables should be replaced at a qualified
workshop. Volkswagen dealerships always have the latest information about any changes.

WARNING
Unsuitable service fluids and consumables, and the incorrect use of these fluids and consumables,
can cause accidents, serious injuries, burns or poisoning.

When the engine is working hard, the engine oil level should be kept within the upper permissible
area ⇒ Fig. 186  Ⓒ, for instance during extended motorway journeys in summer, when towing a
trailer ⇒ Trailer towing , or when climbing mountain passes.

Engine oil level too low – fill engine oil.
Checklist
Carry out the steps in the specified order ⇒ :

With the engine at operating temperature, park the vehicle on a level surface to ensure that the
engine oil reading is correct.

Switch off the engine and wait a few minutes for the engine oil to flow back into the sump.

Open the bonnet In the engine compartment.

Identify the engine oil filler cap and oil dipstick. The engine oil filler opening can be recognised by
the symbol on the cap and the oil dipstick has a coloured handle. If you cannot find the cap and
dipstick, please contact a qualified workshop.

Pull the dipstick out of the guide tube and wipe it off with a clean cloth.

Insert the oil dipstick into the guide tube again as far as it will go. If there is a marking on the upper
end of the oil dipstick, this marking must fit into the corresponding groove at the top end of the
guide tube upon insertion.

Engine oil can, e.g. in the case of high engine loads , be filled up to the upper limit of this range.
Continue with step 8 or 16. Ⓓ Engine oil level is too low. Engine oil must be filled. Continue with
step 8.

After reading off the oil level, push the oil dipstick back into the guide tube as far as it will go.

Unscrew the cap of the engine oil filler opening .

Using only the engine oil approved by Volkswagen expressly for this engine, fill oil gradually in small
amounts (no more than 0.5 l).

damage.

The engine oil level must never be above area ⇒ Fig. 186  Ⓑ. Otherwise oil can be drawn in through
the crankcase breather and escape into the atmosphere via the exhaust system.

Various indicator lamps may light up after the 12-volt vehicle battery has been connected and the
ignition is switched on. They will go out when you drive a short distance at a speed of approximately
15 – 20 km/h (10 – 12 mph). If the indicator lamps remain lit up, the vehicle should be checked by a
qualified workshop.
If the 12-volt vehicle battery was disconnected for an extended period, the system may not able to
calculate or correctly display the time when the next service is due ⇒ Instrument cluster . Observe
the maximum permissible service intervals ⇒ Service .
Automatic switch-off for electrical consumers
The intelligent vehicle electrical system management function automatically implements a range of
measures to prevent the 12-volt vehicle battery from discharging under high loads:


power supply to the 12-volt socket and the cigarette lighter may be interrupted temporarily
while the engine is being started.
The vehicle electrics management system cannot always prevent the 12-volt vehicle battery from
being discharged, for example if the ignition is left on over a long period with the engine off or the
side lights or parking lights are left on over a long period of time.

Introduction
This chapter contains information on the followingsubjects:
⇒ Tyre Pressure Loss Indicator 
⇒ Troubleshooting for Tyre Pressure Loss Indicator 
The tyre monitoring system warns the driver when the tyre pressures are too low.
The tyre monitoring system monitors various parameters (for example, rolling circumference) of all
wheels using ABS sensors (indirect measurement).

WARNING
The intelligent tyre monitoring system technology cannot overcome the laws of physics, and
functions only within the limits of the system. Incorrect handling of the wheels and tyres can lead to
a sudden loss of pressure in the tyres, tread separation and even tyre blow-out.

The Tyre Pressure Loss Indicator may react with a delay or not display anything at all in the event

driving with snow chains.
