Progressive steering
Depending on the vehicle equipment level, progressive steering can adjust the force of the steering
movement in a driving situation. Progressive steering only functions when the engine is running.
In urban driving, smaller steering movements are required when parking, manoeuvring, or turning
sharply.
When driving on country roads or on the motorway, the progressive steering provides a more
sporty, direct steering response, and a dynamic feel.

vehicle setup by means of an individual
driving profile.
Different driving profiles can be selected depending on the vehicle equipment level. The effect on
the vehicle setup in the individual driving profiles depends on the vehicle equipment.
The settings available depend on the type of drive. Vehicles with a front-wheel drive come with
ONROAD driving profiles ⇒ Selecting a driving profile (ONROADyf, while vehicles with all-wheel
If the power steering is not working, the steering wheel is difficult to turn, which makes it
difficult to steer the vehicle.
•The power steering only functions when the engine is running.
•Never allow the vehicle to roll if the engine is switched off.
•Never remove the vehicle key from the ignition lock when the vehicle is in motion. The
steering column lock may be activated and it will no longer be possible to steer the
vehicle.
WARNING
In conjunction with the ESC, counter steering assistance provides the driver with
assistance when steering in critical driving situations. The driver must steer the vehicle at
all times. Counter steering assistance does not steer the vehicle.

You can also drive four-wheel drive vehicles off-road in addition to normal roads. It is very important
to read the contents of this section before driving off-road.
The vehicle is not built for expeditions.
The examples given in this chapter are an aid for safe off-road driving. However, we cannot predict
whether these guidelines will be valid for all situations that could occur.
The large variety of landscapes and the associated risks and dangers make it impossible to
describe all possible driving situations. The examples are only general guidelines designed to help
you drive off-road safely. It is crucial that you know what to expect when you drive into off-road
terrain you are unfamiliar with. This will enable you to assess potential danger in advance.
Accidents and injuries can occur if the driver is distracted. Operating the Infotainment
system can distract you from the road.
•Always drive carefully and responsibly.
WARNING

Explanation of some technical terms
Fig. 131 Illustration: angle of gradient.
The terrain might look harmless, but there could be hidden dangers. Potholes, hollows,
ditches, precipices, obstacles, shallows, soft and boggy surfaces are often not
recognisable as such and can be covered either fully or partly by water or grass or
branches lying on the ground. Driving off-road over such terrain could cause accidents,
serious injury and also a vehicle breakdown.
•Check any unknown sections of the route on foot carefully before driving.
•Never choose an unsafe route or take a risk which could endanger you or your
passengers. If you are in any doubt about the safety of the route, turn back and choose
another route.
•Always adjust your speed and driving to match vehicle load levels and off-road,
visibility and weather conditions.
WARNING
•Always avoid traversing a slope ⇒ Traversing a slope.

WARNING
The cruise control system has been designed for use on surfaced roads only. The cruise
control system is not suitable for use off-road and may even be hazardous. If you use the
cruise control system while driving off-road, you may lose control over the vehicle and
sustain severe injuries.
•Never use the cruise control system when driving off-road.

The area monitoring system is not suitable for use off-road and may even be hazardous. If
you use the area monitoring system while driving off-road, you may lose control over the
vehicle and sustain severe injuries.
•Never use the area monitoring system when driving off-road.
WARNING
Driving the vehicle when the fuel level is too low could lead to your vehicle breaking down
off-road, accidents and serious injuries.
•When the fuel level is too low, the fuel supply to the engine could be irregular,
especially when driving up or down hills and inclines.
•The steering, all driver assist systems and brake support systems will not function if
the engine sputters or stops completely due to a lack of fuel or irregular fuel supply.
•Always fill the tank when it is still 1/4 full. This reduces the risk of running out of fuel
and breaking down.
WARNING
Any rain entering the vehicle when the windows or glass roof are open can soak the
interior equipment and cause damage to the vehicle. Always keep the windows and glass
roof closed when driving off-road.
NOTICE

Obtain sufficient information before driving into off-road terrain with the vehicle.
Do not plan day tours that are too long. Take increased fuel requirements for off-road
driving into account.
Refill tank completely. Fuel consumption is considerably higher off-road.
Check that your tyres are suitable for the off-road journey you have planned.
Recommendation for difficult off-road terrain: always have off-road tyres fitted to your
vehicle.
Check the tyre pressure on all tyres and correct them if necessary. This includes the
temporary spare wheel, if fitted.
Check engine oil level and refill engine oil as necessary. The engine will only be supplied
with engine oil when it is driven on or across a steep slope if the engine oil level is
sufficient.
Completely refill the washer fluid reservoir with water and washer fluid.
Fit the towing eye at the front and rear. It is not always possible to fit a towing eye when
the vehicle is stuck.
Check the vehicle tool kit and add tools according to individual requirements Useful
accessories for off-road driving.
Pack luggage in the vehicle as evenly and as low as possible. Secure all loose items.
Fig. 132 Illustration: angle of tilt.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Centre of gravityThe centre of gravity of a vehicle influences its propensity to roll over. The vehicle
has greater ground clearance for off-road driving, and thus a higher centre of gravity than a normal
vehicle. The high centre of gravity means that there is a greater danger of roll-over when driving.
Always remember this fact when driving and follow the safety tips and warnings given in this
owner's manual.Ground clearanceThis is the vertical distance between the level ground and the
lowest item on the vehicle.Angle of rising gradientThe number of metres in height gained over a

Checklist: Before driving off-road
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Checklist
To ensure your own safety and the safety of your passengers, observe the following points
before driving off-road:
Before driving off-road, Volkswagen recommends attending an off-road driving course, particularly if
you have no or very little experience.
A good driving course will teach you how to handle the vehicle in a variety of off-road situations and
how to drive safely in difficult terrain. Driving off-road demands different skills and driving styles in
comparison to driving on roads. The safety of the driver and the vehicle occupants depends on the
driver.
General rules and driving tips
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Code of conduct for off-road driving
A responsible driver should respect the environment when driving off-road. Remember that driving
through undergrowth and on meadows can destroy animal and plant habitats.
•Always stay on designated routes and paths.
•Do not create any unnecessary noise or dust.
•Leave nature as you found it.
•Avoid sensitive natural habitats.

Water, compass, maps and torch with spare batteries.
Winch, tow bar or rope with sufficient strength.
Mobile telephone, shovel, blankets and rubber boots.
Electric air compressor for connection to the 12-volt sockets in the vehicle to inflate the
tyres.
A wooden board approx. 4 cm thick and approx. 1 metre long or an aluminium frame of
similar size: this will help to free a vehicle stuck in the mud and provide a platform for a
vehicle jack.
Snow chains, additional spare wheels, a breakdown set, jack and box spanner.
•Give way to drivers coming uphill or who are overtaking.
Driving tips
Special rules apply when driving off-road:
•Never drive off-road alone. Always drive off-road in a team of at least two other off-road
vehicles. Unexpected situations can always occur. We recommend that you carry equipment
you can use for calling for help.
•Stop your vehicle when you reach difficult sections, and walk along the path ahead to
reconnoitre it.
•Drive slowly over the brows of hills so the vehicle does not lose contact with the ground as this
could cause damage, leaving you unable to manoeuvre.
•Drive slowly when the route is difficult. Shift up a gear when on slippery ground and always
keep the vehicle in motion.
•Always look for flat and firm surfaces. The ground is predominantly soft when driving off-road
meaning the tyres could sink into the ground. This will reduce ground clearance and the wading
depth.
•Even when driving at low speeds, always keep your distance from other vehicles. If the first
vehicle suddenly gets stuck, the following vehicle can stop without getting stuck.
Useful accessories for off-road driving
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The checklist contains just a few items of equipment that can be very useful for off-road driving. If
you have an instruction manual or fitting instructions for these accessories you should always take
them with you and consult them as necessary when driving off-road.
Checklist
Useful items when driving off-road:
Changing gear
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The choice of gear depends on the terrain off-road.
Before attempting to drive through difficult terrain it can be helpful to stop and consider which gear
you should select. After some time driving off-road, you will learn which gear to select in conjunction
with the low range and the differential lock for different types of terrain.
Basic points
•With the correct gear selected, the vehicle will normally not have to be braked so much using
the foot brake when driving downhill as the engine braking effect will normally be sufficient.
•You should only depress the accelerator as much as is required. If you accelerate too hard, the
wheels could lose traction and you could lose control of the vehicle.
DSG dual clutch gearbox
•Select position D when driving in normal, flat off-road terrain.
•Adjust your speed when driving on soft or slippery ground, and select the highest suitable
position for the Tiptronic.
•If driving through mud, sand, water or hilly terrain, select the Tiptronic in the positions 3 or
2⇒ DSG dual clutch gearbox.
•Always ensure that there is enough ground clearance underneath the vehicle. Serious
damage to the underbody could occur if the vehicle is scraped. This damage could
cause the vehicle to break down and thus make it impossible to drive on.
•Do not slip the clutch or rest your foot on the clutch when driving off-road. When
travelling over uneven ground, you could press the clutch by mistake, and lose control
of the vehicle. A slipped clutch also prevents power being transferred from the engine
to the gearbox. Driving with the clutch partially engaged causes premature wear to the
clutch lining.

You should drive through rocky terrain at walking pace.
If you are not able to drive around a stone, drive carefully onto the stone with one front wheel and
drive over it slowly ⇒.
Escaping engine oil and brake fluid can pollute the environment. Spilt service fluids must be
collected and then disposed of properly and in an environmentally responsible way.
Driving through water
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Driving through flooded terrain could damage the vehicle ⇒ Checklist: Before driving off-road.
You can drive the vehicle carefully through water with a depth reaching to the bottom edge of the
body, for example puddles or shallow water. Never stop in the water, do not drive in reverse, and
never switch off the engine.
Off-road driving in snow
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Fit snow chains to the front wheels only before driving on snow-covered terrain.
Terrain might look harmless, but there could be hidden dangers. This is particularly true of sections
where there are no tyre tracks.
•You should never drive straight over large obstacles, e.g. boulders or tree stumps, or
drive over such obstacles with one side of the vehicle. Obstacles which require more
ground clearance than is available could damage vehicle components when you drive
over them and thus cause the vehicle to break down.
•Even obstacles that are smaller than the ground clearance selected could come into
contact with the vehicle underbody and thus cause damage which could lead to a
vehicle breakdown. This applies in particular if there is a ditch or soft ground either in
front of or behind the obstacle. This also applies in cases when you drive too quickly
over the obstacle causing the vehicle to bounce.
NOTICE
Strong flowing water can develop enormous power and sweep the vehicle away. This can
lead to very dangerous situations which can cause accidents and serious or even fatal
accidents.
•Never allow the vehicle to stand still in water.
•Water in the engine compartment can cause the vehicle to breakdown in the water.
•Soft ground surface, underwater obstacles and shallows can cause accidents and can
cause the vehicle to breakdown in the water. This could lead to critical situations.
WARNING
If you drive through water, parts of the vehicle, such as the engine, drive train, running
gear and vehicle electrics, could sustain severe damage.
•When driving through water, always select a section where the ground is solid and
where the depth of the water does not exceed the maximum permitted wading depth of
the vehicle.
•Never drive through salt, salty surfaces or salt water as salt can cause corrosion. Rinse
all components that have been exposed to salt or salt water thoroughly with fresh
water.
NOTICE

Clean the turn signals, headlight system, the number plate and all windows.
If necessary, remove the towing eye and the snow chains.
Check the tyres, struts and axles for damage and remove dirt, stones and other foreign
bodies from the tyre tread.
Inspect the vehicle underbody and remove all items that are jammed in the brake system,
on the wheels, in the running gear, in the exhaust system and in the engine, such as
branches, leaves or pieces of wood . If you see any damage or leaks, take your vehicle to a
qualified workshop.

First read and observe the introductoryinformation and safety warnings⇒
Introduction
Rocking out a vehicle requires a great deal of training and feeling for the vehicle.
If you make a mistake when rocking the vehicle, it can sink deeper and you will need assistance to
get out of the mud.
When you cannot proceed ...
•Carefully dig out all the wheels and check that no other parts of the vehicle are stuck in the
sand.
•Engage reverse gear.
•Reverse over your own tracks, accelerating gently.
If this does not help, place brushwood, floor mats or sacking directly in front of the wheels to
increase grip ⇒.
Rocking the vehicle
Never allow the wheels to spin for long periods as this will cause the vehicle to sink deeper ⇒.
•Switch off TCS ⇒ Brake support systems.
•Position the steering wheel so that it is facing straight ahead.
•Reverse until the point where the wheels just start to spin.
•Quickly select first gear and drive forwards until the wheels start to spin again.
•Repeat driving back and forth until you have enough momentum to free yourself.
•Switch the TCS on after the rocking procedure is completed ⇒ Brake support systems.
•Use the Off-road driving profile.
After off-road driving
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Checklist
Never drive through a ditch if the entry/exit angle is too steep for the vehicle and the ditch
is too deep. The vehicle could slide away, tip over or roll.
WARNING
If you drive into the ditch at a right angle, the front wheels will fall in. The underbody of
your vehicle could get stuck and damaged which means that the vehicle could break
down. It is then almost impossible to get out of the ditch despite having all-wheel drive.
NOTICE
Nobody may stand either in front or behind the vehicle, particularly if you are attempting
to free a stuck vehicle.
•Spinning wheels can propel stones, brushwood, pieces of wood or other objects that
are in front or behind the wheels at enormous speed and cause potentially fatal injury.
•People standing in front of or behind the vehicle could be run over if the stuck vehicle
starts to move suddenly.

Trailer Assist
Introduction
This chapter contains information on the followingsubjects:
⇒ Prerequisites
⇒ Operation
⇒ Troubleshooting
Trailer Assist helps the driver when
reversing or manoeuvring the vehicle
when towing a trailer.
The trailer manoeuvring system steers a trailer by adjustment of the rotary knob for the exterior
mirrors. The driver must control the accelerator, gear changes and brake!
System limits
The camera may not always be able to detect objects such as trailer drawbars, thin rails, fences,
posts, trees and open or opening boot lids. This can result in damage to your vehicle.
The camera must be kept clean and free of ice and snow, and must not be covered up by stickers
or other objects, as this will prevent the system from working properly. The drawbar must not be
covered.
Trailer Assist should only be used when the boot lid is fully closed.
The trailer manoeuvring system will be automatically ended around ten minutes after
activation. The function will also be ended if no driver interaction is detected within a period of
approximately three minutes.
Prerequisites
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The following prerequisites must be met for the trailer manoeuvring system to function:
•Engine running.
•ESC is switched on.
•Driver door and boot lid are closed.
•Exterior mirrors are not folded in.
•A single- or- two-axle trailer without steered axles is hitched to the vehicle and electrically
connected.
•Vehicle and trailer are stationary.
•Do not exceed the maximum jack-knifing angle.
•The drawbar length has been determined.
Determining the drawbar length
Trailer Assist requires a few turning and cornering manoeuvres to enable it to determine the length
of the drawbar. The more accurately it can determine the length of the drawbar, the bigger the
angles available when manoeuvring. The trailer manoeuvring system divides the available
maximum limit positions on the angle display into four steps: approx. 30°, 45°, 60° and 75°.
For technical reasons, the trailer manoeuvring system cannot always detect trailers with LED
rear lights correctly.
The trailer manoeuvring system does not use the area around the vehicle for orientation.
No obstacle detection takes place. Drivers must judge for themselves whether the trailer
can be manoeuvred safely.
•Always pay close attention to the movements of the trailer and, if required, stop the
manoeuvre to avoid causing any damage. On rare occasions the trailer may behave
differently, even when Trailer Assist is operated correctly.
•Do not rely only on the displays in the instrument cluster.
NOTICE
