taking any risks when driving – this can cause accidents.
•Unintentional vehicle movements can cause serious injury.
•The pull-away assist systems cannot replace the full concentration of the driver.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions.
•A pull-away assist system cannot hold the vehicle in all hill start situations or brake it
sufficiently on all slopes going downhill (e.g. if the ground is slippery or icy).
WARNING
Failure to observe the warning lamps could lead to your vehicle breaking down in traffic, and
to accidents and serious injuries.
•Never ignore any warning lamps that are lit up.
•Stop the vehicle as soon as it is possible and safe to do so.

Preparing the vehicle for working in the engine compartment
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Checklist
The following steps should always be carried out in the specified order before working in the
engine compartment ⇒:
There are rotating components in the engine compartment that can cause serious injury.
•Never place your hand near or directly in the radiator fan. Touching the rotary blades can
result in serious injuries. The fan is temperature-controlled and can start automatically,
even if the engine has been switched off and the vehicle key has been removed from the
ignition lock.
•If any work has to be performed when the engine is started or with the engine running,
there is an additional, potentially fatal, safety risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always be
particularly careful.
- Always ensure that no body parts, jewellery, ties, loose items of clothing or long hair
can be caught up in rotating engine components. Before starting work, remove any
jewellery and ties, tie up long hair and pull clothes in tightly to avoid them getting
caught in the engine compartment.
- Always depress the accelerator carefully and never without due consideration. The
vehicle can start to move even if the handbrake is applied.
•Always ensure that you have not left any objects, such as cleaning cloths and tools, in the
engine compartment. Any forgotten items can cause malfunctions, engine damage and
fires.
WARNING
Operating fluids and some materials in the engine compartment are highly flammable and can
cause fires and serious injuries!
•Never smoke while working on the vehicle.
•Never work near naked flames or sparks.
•Never spill fluids onto the engine. They could ignite on hot engine components and hence
cause injuries.
•Please note the following when carrying out any work on the fuel system or the electrical
system:
- Always disconnect the vehicle battery.
- Never work in the direct proximity of heating systems, water heaters or any other
open flames.
•Always have a fully functional and tested fire extinguisher to hand.
WARNING
When refilling or changing operating fluids please ensure that the fluids are in the correct
container. Incorrect operating fluids can cause serious functional problems and engine
damage.

NOTICE

Charging, replacing, disconnecting and connecting the vehicle battery
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Charging the battery
The vehicle battery should be charged by a qualified workshop, as the technology used in factory-
fitted batteries requires voltage-limited charging ⇒. Volkswagen recommends using a
Volkswagen dealership for this purpose.
Replacing a vehicle battery
The battery has been developed to suit the conditions of its location and has special safety
features. If a vehicle battery has to be replaced, discuss the electromagnetic compatibility, size and
necessary servicing, output and safety requirements for the new vehicle battery with a Volkswagen
dealership before purchase. Volkswagen recommends that the vehicle battery is changed by a
Volkswagen dealership.
Only maintenance-free vehicle batteries compliant with the standards TL 825 06 and VW 7 50 73
should be used. These standards must be dated April 2008 or later.
Vehicles with start/stop system ⇒ Pull-away assist systems are equipped with a special vehicle
battery. These vehicle batteries may only be replaced by a vehicle battery with the same
specifications.
Disconnecting the vehicle battery
Please note the following if the vehicle battery has to be disconnected from the electrical system in
the vehicle:
•Switch off all electrical consumers and the ignition.
•Unlock the vehicle before disconnecting the battery in order to avoid triggering the alarm.
•First disconnect the negative cable and then the positive cable ⇒.
Connecting the vehicle battery
•Switch off all electrical consumers and the ignition before reconnecting the vehicle battery.
•First reconnect the positive cable and then the negative cable ⇒.
Various indicator lamps may light up after the vehicle battery has been connected and the ignition is
switched on. They will go out if you drive a short distance at a speed of 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 vehicle battery was disconnected for long periods, the system may not able to calculate or
correctly display the time when the next service is due ⇒ Instruments. Comply with the maximum
permissible service intervals ⇒BookletService schedule,.
Automatic switch-off for electrical consumers
The intelligent vehicle electrical system automatically implements a range of measures to prevent
the battery from discharging under high loads:
•The idling speed is increased so that the alternator provides more electricity.
•The performance of large electrical consumers may be reduced or they may be switched off
completely.
•The power supply to the 12-volt socket and the cigarette lighter is interrupted temporarily while
the engine is being started.
The vehicle electrical system cannot always prevent the vehicle battery from discharging. For
example when the ignition is switched on for an extended period with the engine off, or when the
side or parking lights are on when the vehicle is parked for an extended period.
Any work on the vehicle battery can cause serious chemical burns, explosions and electric
shocks.
•Always wear eye protection and protective gloves.
•Electrolyte is very aggressive. It can burn the skin and can cause blindness. When
working with the battery, protect your hands, arms and particularly your face from acid
spillages.
•Never tilt the vehicle battery. Electrolyte may spill out of the battery vents and cause
chemical burns.
•Never open a vehicle battery.
•If acid is splashed onto your skin or into your eye, rinse immediately for several minutes
with cold water. Then consult a doctor immediately.
•If acid is swallowed, consult a doctor immediately.
