WARNING
Off-road driving can be dangerous, can lead to accidents, vehicle damage, stranding in remote areas, and serious personal injury.
x Never drive too fast or for terrain and weather conditions.
x Always adjust your speed and driving style to road, terrain, traffic, and weather conditions.
x Always avoid sudden, sharp maneuvers that increase the risk of loss of vehicle control or getting stuck.
x When driving off-road look and think ahead, expect the unexpected.
x To reduce the risk of loss of control and serious personal injury, never use the cruise control when driving off-road. Cruise control is designed for highway use. It is completely unsuitable for off-road situations and can even be dangerous when used off-road.
NOTICE
Always make sure the vehicle has enough ground clearance. Severe damage to the underbody can occur if the vehicle bottoms out. The damage could disable the vehicle and leave you stranded.
x While driving off-road do not drag the clutch or rest one foot on the clutch pedal. Otherwise, in bumpy terrain you might press the clutch accidentally, resulting in loss of vehicle control. In addition, the frictional connection between the engine and transmission is lost. Further, driving while dragging the clutch causes fast wear of the clutch lining.

be lower on hard, firm surfaces if ideal conditions do not exist. As the driver, you are always
responsible for deciding whether your vehicle is able to handle a particular situation ⇒ .

Term Explanation Technical data
Ground clearance This is the vertical distance between the level ground and the lowest part on the vehicle.
Maximum 7.6 in (195 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. 159 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 27 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 21.3 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.
Approach angle for off-road front end: Maximum 28 degrees.
Departure angle: Maximum 25 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.

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

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.
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

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 clutch depressed or the transmission in Neutral (N). You could lose control of the vehicle.
Driving crosswise on a slope

Working in the engine compartment

WARNING
The engine compartment of any motor vehicle is a potentially dangerous area and can cause serious personal injury.
x Always use extreme caution when doing any work in the engine compartment. Always follow commonly accepted safety practices and use common sense. Never risk personal injury.
x Never perform any work in the engine compartment unless you know exactly how to carry out the job and have the correct technical information and the correct tools.
x If you are uncertain about what to do, have the work performed by an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID - High Intensity Discharge (Xenon) lights and H7/H15 bulbs replaced by a qualified technician. Serious personal injury may result from improperly performed work.
x Never open or close the engine hood if steam or coolant is escaping. Hot steam or coolant can cause serious burns. Always wait until you no longer see or hear steam or coolant escaping from the engine.
x Always let the engine cool down completely before carefully opening the hood.
x Hot parts of the engine and the exhaust system will burn skin on contact.
x When the engine has cooled down and you are ready to open the hood:
– Firmly apply the parking brake and shift the transmission into Park (P) (automatic) or Neutral (manual only).
– Take the vehicle key out of the ignition.
– On vehicles with Keyless Access, make sure that the remote control vehicle key is out of range of the vehicle and that the vehicle cannot be started by depressing the starter button.
– Always keep children and others away from the engine compartment and never leave them unsupervised.
x The engine coolant system is under pressure when the engine is hot. Never unscrew the coolant expansion tank cap when the engine is hot. Hot coolant can spray out and cause severe burns and other serious injuries.
– Turn the cap slowly and very carefully in a counterclockwise direction while applying light downward pressure on the top of the cap.
– Always protect your face, hands, and arms from hot escaping coolant or steam by covering the cap with a large, thick rag.
x Never spill fluids on the engine or exhaust system when refilling. Spilling fluids onto hot parts of the engine or exhaust system can cause a fire.

WARNING
High voltage systems in the engine compartment can cause electrical shocks or even electrocution, severe burns, other serious injuries, and even death!
x Never short-circuit the electrical system. Be especially careful when using jumper cables. The vehicle's battery could explode!
x To reduce the risk of electrical shock and personal injury while the engine is running or being started:
– Never touch ignition cables. Never touch other components of the high voltage electronic ignition system.
– Never touch the wiring of the HID - High Intensity Discharge (Xenon) headlights.
x Read and heed the important information and warnings on cleaning the engine compartment
WARNING
Moving parts in the engine compartment can cause serious personal injury on contact.
x Never reach into the area around or touch the radiator fan. Contact with the blades can cause serious personal injury. Always remember that the radiator fan is temperature-controlled and can come on suddenly even when the engine has been switched off for a while and the key has been removed from the ignition.
x If you have to perform a check or repair when the engine is running, there are more risks from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always use extreme care.
– Always make sure that jewelry, loose clothing and long hair do not get caught in rotating engine parts. Before starting any work remove your jewelry, take off your necktie, tie back and cover your hair, and do not wear clothing that can hang down and get caught in moving engine parts.
– Always use extreme caution if the accelerator pedal has to be depressed to perform a check. The vehicle will start to move even if the electronic parking brake is on.
x Never leave any objects in the engine compartment, for example cleaning rags and tools. Objects left behind can cause malfunctions, engine damage, and even fires.
WARNING
Operating fluids and some materials in the engine compartment can catch fire easily, causing burns and other serious personal injuries!
x Do not smoke.
x Never work next to open flames or sparks.
x Never pour or spill operating fluids or other flammable liquids on the engine. These fluids can ignite on hot engine parts and cause injuries.
x If work on the fuel system or the electrical system is necessary:
– Always disconnect the 12 Volt vehicle battery. Make sure the vehicle is unlocked when you disconnect the battery, or the alarm will go off. Never touch the electrical wiring of the ignition system.
– Never work near heaters, water heaters, or other open flames.
x Always have a functional, approved fire extinguisher nearby.

NOTICE
When changing or topping off fluids, make sure that you pour the fluids into the correct reservoirs. Adding the wrong type of operating fluids will cause serious malfunctions and engine damage.
Fluid leaks are harmful to the environment. Regularly check the ground underneath your vehicle for this reason. If you find spots of oil or other fluids, have your vehicle checked by your authorized Volkswagen dealer or authorized Volkswagen Service Facility. Dispose of leaked operating fluids properly.
