Refilling AdBlue
Only use Volkswagen-approved AdBlue or any Diesel Exhaust Fluid that expressly conforms to International Organization for Standardization specification ISO 22241-1. Using a DEF that does not meet the requirements of ISO 22241-1 can seriously damage your vehicle’s engine. Only use fluid in original, unopened packaging.
x Read and heed the information provided by the AdBlue refill manufacturer ⇒ .
x Note the expiration date.
x Unscrew the cap of the refill container.
x Vertically insert the neck of the refill container (6) into the tank filler neck and turn clockwise to hand-tighten.
x Press the refill container down into the tank filler neck and hold it there.
x Add at least 1.5 gallons (5.7 liters) of AdBlue which is 3 refill bottles. Adding a smaller amount is not sufficient.
x Wait until the contents of the refill container has flowed into the AdBlue tank. Do not squeeze or damage the refill container!
x Unscrew the refill container counterclockwise and lift it out carefully ⇒ .
x AdBlue stops flowing from the refill bottle when the AdBlue tank is completely full.
Closing the fuel filler neck
x Screw in the fuel filler neck cap (5) clockwise until the cap locks into place.
x Put the plug ⇒ fig. 308 (4) back in the spare wheel recess and make certain it is properly placed and secure.
x Put the collapsible spare tire (2) back in the spare wheel recess and secure it with the fastening screw (3) and washer.
x Unhook the luggage compartment floor panel (1) and fold down or, if you have a reversible lug-
gage compartment floor panel, put this back in ⇒  Luggage compartment.
Things to do before driving again
x After refilling, switch on only the ignition.
x Leave the ignition switched on for at least 30 seconds so that system can detect the refill.
x Do not start the engine for 30 seconds!
WARNING
Store AdBlue only in its closed original container and in a safe place.
x To reduce the risk of poisoning, never keep AdBlue in empty food or beverage containers that might mislead someone into drinking from them.
x Always store AdBlue outside the reach of children.

NOTICE
x Use only AdBlue® or any Diesel Exhaust Fluid that expressly conforms to International Organization for Standardization specification ISO 22241-1. Using a DEF that does not meet the requirements of ISO 22241-1 can seriously damage your vehicle’s engine.
x Never mix water or any other substances or additives with AdBlue. Damage caused by such additives will not be covered by any Volkswagen Limited Warranty.
x Never put AdBlue into the diesel fuel tank! Otherwise the engine may be damaged!
x Do not carry a refill container in the vehicle all the time or routinely. Due to temperature fluctuations and damage, the container could start leaking and the AdBlue could damage the vehicle interior.
Dispose of the refill container in an environmentally-responsible manner.
Appropriate AdBlue refill containers can be obtained from an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.

Some basics

WARNING
Inadequate experience and knowledge of the demands of off-road driving can lead to critical situations and cause serious personal injury.
x Never take routes or risks that could put you or your passengers in danger. If you cannot go on, or have doubts about the safety of your route, turn back and take a new route.
x The intelligent technology of the vehicle cannot change the laws of physics. Despite the ABS, adverse terrain can cause instability through blocked wheels – for example, if you brake hard when driving on a loose gravel road. Difficult terrain may also prevent the ESC from doing its job.
x Never operate the vehicle at the limit of its performance ability. Always leave a good safety margin.
x To reduce the risk of loss of control and serious personal injury, never use the cruise control when driving off-road.
x Even terrain that looks easy can be difficult and dangerous, putting you and your passen-gers in a critical situation. It is often best to check an area out on foot first.
x Drive with special care and think ahead in off-road terrain. If you drive too fast, or fail to maneuver the vehicle properly, you could cause personal injury and damage the vehicle.
x Never drive faster than is appropriate for the prevailing terrain and the road, traffic, and weather conditions.
x Never drive too fast across embankments, ramps, or slopes. The vehicle could become airborne. If that happens, you will not be able to steer and can lose control.
x If your vehicle becomes airborne, always keep the front wheels pointing straight ahead. If the wheels are not pointing straight ahead when the vehicle lands, it could roll over.
x Never allow people to stand in front of or behind the vehicle if you have put items such as stones or pieces of wood under the wheels to improve traction on slippery ground. Spinning wheels can turn these items into dangerous flying objects causing serious personal injury.
x Even areas that look harmless can be dangerous. Potholes, ditches, trenches, drop-offs, different kinds of obstacles, and soft or swampy ground often cannot be seen and can be partially or fully covered by water, grass, branches, or other things. Driving over such terrain can cause accidents and severe injuries. Before crossing an unknown area, carefully explore the route you plan to take on foot.
WARNING
Never drive off-road if you are low on fuel. Too little fuel in the tank can cause an accident and serious injuries. You can also run out of fuel in a remote area where getting help is diffi-cult or impossible.
x When the fuel tank is almost empty, fuel supply to the engine can be interrupted, especial-ly when driving over bumps, across slopes, and up and down hills. The interruption in fuel flow could stall the engine during a maneuver in difficult terrain and make you lose control of the vehicle.
x Steering and braking assistance as well as ESC and related systems will not work if the engine “sputters” or stalls due to lack of fuel. This can cause loss of vehicle control, espe-cially in difficult terrain.
x Always refuel when the tank is 1/4 full to reduce the risk of running out of fuel.
NOTICE
If the power sunroof or the windows are open when it rains or snows, the interior of the vehicle will get wet and the vehicle may be damaged. Always keep the windows and the power sunroof closed when driving off-road.
