2014 VOLKSWAGEN TOUAREG engine

AdBlue is stored in a separate tank of the vehicle and should be refilled under normal driving conditions during service according to the maintenance schedule. The AdBlue tank holds slightly less than 5 gallons (20 liters).
AdBlue consumption depends on the individual driving style, system operating temperature, and outside air temperature. Therefore in rare cases AdBlue may have to be refilled between service events.
Starting with a remaining range of about 1500 miles (2400 km), a reminder to refill AdBlue is displayed
in the instrument cluster ⇒ Refilling AdBlue. If you ignore the last refill reminder, it is impossible to
start the engine again after it is switched off ⇒ Warning and indicator lights.
Volkswagen recommends that you have the AdBlue tank refilled by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. If no authorized Volkswagen dealer or authorized Volkswagen Service Facility or other qualified workshop is available, you should refill at least 1.5 gallons (5.7 liters) of AdBlue (3 AdBlue bottles). Refill only the type of AdBlue that Volkswagen has explicitly approved for your vehicle.
If warning lights b and > both come on together, there is a malfunction. Volkswagen recommends that you take the vehicle to the closest qualified workshop.

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 that has been explicitly approved by Volkswagen. Using other types of AdBlue can 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.

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 passengers 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 difficult or impossible.
x When the fuel tank is almost empty, fuel supply to the engine can be interrupted, especially 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, especially 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.

Term Explanation Technical data
Ground clearance This is the vertical distance between the level ground and the lowest part on the vehicle.

Fording depth in standing water Distance between the point on the ground that touches the tire and the engine air intake duct.
Maximum 20 inches (500 mm).
Gradient angle The number of feet (meters) in altitude gained when traveling 100 ft (30.48 m) is given as a percentage or in degrees
⇒ fig. 292 A. Information on the maximum slope the vehicle can climb unassisted (depends on road surface and engine power).
Maximum permissible 31 degrees (corresponds to 60 %).
Lateral angle (vehicle slope) The maximum angle the vehicle may be driven across terrain without the vehicle rolling over (depends on height of center of gravity) B.
Maximum permissible 35 degrees.
Breakover angle Maximum permitted angle given in degrees that a vehicle driven at low speed can clear a ramp without the underbody of the vehicle scraping the ramp
Maximum 20 degrees.
Approach/departure angle Transition from horizontal plane to a slope, or from a slope to flat ground. Maximum angle in degrees the vehicle can be driven at low speed along an embankment without the bumper or underbody scraping.
Front: maximum 25 degrees. Rear: maximum 26 degrees.
Fall line This is the vertical drop route.
Articulation Articulation capability of the vehicle while driving on one side over an object.
WARNING
Never exceed the recommended maximum values in the above table. Exceeding these values will result in serious personal injury and/or damage to your vehicle.
x All values listed above are for ideal conditions and assume firm, even surfaces that are dry and not slippery.
x Off-road conditions will always be less than ideal. Always reduce the maximum values listed in the table above to allow an adequate margin of safety between the ideal maximum value and your vehicle's actual off-road situation.

them. They are also dangerous if you drive over them too quickly and the shock absorbers are compressed.
Leaking engine oil and brake fluid can pollute the environment. Collect leaking operating fluids and dispose of them properly in accordance with applicable environmental laws and regulations.
Driving through water

Headlight washer system instructions
Do not use the headlight washer system when driving through water. Things in the water can enter into the openings when the washer nozzles are extended. This can prevent the washer nozzles from retracting to their normal position. If this should happen, carefully remove the objects.
After driving through water
x After crossing through deep water, stop the engine and check the oil dipstick. If there are beads of water on the oil dipstick or the oil level has increased, do not start the engine. Change the engine oil immediately. Depending on the amount of water in the oil, running or starting the engine can result in engine failure or serious engine damage.
x Always dry the brakes by braking a couple of times.
x After driving through water, have the vehicle drive train and electrical system thoroughly inspected for damage by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
WARNING
Flowing water is very powerful and can sweep your vehicle away. This can lead create an extremely dangerous situation and cause an accident with serious personal injuries.
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 Never stop in the water.
x If water gets into the engine, your vehicle can break down. You will lose control of a broken down vehicle, and it can be swept away.
x Soft surfaces, mud, underwater obstacles, and holes can cause accidents and can cause the vehicle to break down in the water. This can lead pose extreme danger.
x Rapidly flowing water can develop strong forces that can pull the vehicle downstream. This can cause accidents and fatal injuries.
x Drive through water only where the banks and bottom are firm enough and the water is shallower at all points than the maximum permissible fording depth for your vehicle
⇒ table 488.
NOTICE
x Vehicle components such as the engine, drive train, suspension or electrical system may be severely damaged by driving through water.
x Avoid stopping in deep water. This can let water get inside the vehicle.
x On soft ground, the tires dig into the surface. This reduces fording depth. Make sure that the ground is sufficiently firm.
x Avoid creating a bow wave in front of the vehicle while driving through water. A bow wave could force its way into the engine air intake duct and seriously damage the engine.
x If you even briefly exceed the maximum fording depth when driving through water, severe engine damage will result. This engine damage will lead to a vehicle breakdown. This can disable the vehicle in the water.
x Never drive over salt flats or through salt or salty water. Salt causes vehicle corrosion. Rinse all parts of the vehicle that were exposed to salt or salt water right away with fresh water.
Driving over snow-covered terrain

x Gently apply the foot brake to help keep the vehicle under control.
x If it is possible and if it is not dangerous, drive straight down the fall line (maximum slope).
x Do not shift into Neutral (N).
WARNING
Never try to drive up or down slopes that are too steep for your vehicle. The vehicle could slide away, tip over, or roll over.
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 lateral angle must never be more than the maximum angle approved for the vehicle.
x Always drive along the fall line when driving up or down a slope.
x Never try to turn the vehicle around on a slope. The vehicle could tip over or roll down the slope.
x If the engine stalls or you can no longer drive up the slope for any reason, stop and apply the foot brake. If stalled, apply the foot brake and restart the engine. Then shift into Reverse (R) and carefully back your vehicle straight down the slope along the fall line. Keep the vehicle speed slow and even.
x If the engine will not restart, apply constant pressure to the foot brake and carefully back straight down the slope the same way you drove up. Keep the vehicle speed slow and even.
x If the engine is running, select Reverse and carefully back straight down the slope the same way you drove up. Use engine braking power and the foot brake to keep the vehicle speed slow and even.
x Never just roll down a slope with the transmission in Neutral (N). You could lose control of the vehicle.
