Avoid any abrupt or sudden driving and braking manoeuvres as this could cause the open boot lid to
move unpredictably.
Any objects protruding from the luggage compartment must be marked to ensure that they are
visible to other road users. Comply with legal regulations.
If items protrude out of the luggage compartment, never use the boot lid to wedge them into place
or hold them in position.
If you have to drive with the boot lid open, you must remove any carriers and the loads attached to
them from the boot lid.

WARNING
Poisonous exhaust fumes could enter the vehicle interior when the boot lid is open. This could result
in loss of consciousness, carbon monoxide poisoning, serious injury and accidents.
You should always drive with the boot lid closed in order to prevent poisonous exhaust fumes from
entering the vehicle.
If exceptional circumstances require you to drive with an open boot lid, you must do the following to
reduce the amount of poisonous exhaust fumes that could enter into the vehicle:
Close all windows and the glass roof.
Switch off the air recirculation mode of the heating and fresh air system or air conditioning system.
Open all vents in the dash panel.
Switch the blower for the heating and fresh air system or for the air conditioning system to the
highest setting.

NOTICE
The vehicle height, and possibly the length, are different when the boot lid is open.
Driving through water
Please follow these points in order to prevent damage to your vehicle when driving through water,
for example on flooded streets:
Check how deep the water is before driving through it. The water may be no higher than the lower
edge of the body ⇒ .
Do not drive faster than walking speed.
Never stop the vehicle, reverse or switch off the engine while in water.
Oncoming vehicles will create waves that could increase the water level for your vehicle to such an
extent that it is not safe to drive through the water.
Always deactivate the start/stop system manually when driving through water ⇒ Start/stop system .

The vehicle is not built for expedition-type journeys.

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 offroad.
Explanation of some technical terms

Fig. 114 Illustration: tilt angle.
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 offroad 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 ground and the lowest
item on the vehicle underbody.Angle of gradientThe number of metres in height gained over a
distance of 100 m is given as a percentage or degree ⇒ Fig. 113 . Indication of gradient that the
vehicle can drive up under its own power. This depends on aspects such as the road surface and
engine power.Tilt angleMaximum angle at which the vehicle may be driven across a slope without
the vehicle tipping over (determined by centre of gravity) ⇒ Fig. 114 .Breakover angleMaximum
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.Ramp angleCrossover from the horizontal level surface
to an uphill gradient, or from a downhill gradient back to the level surface. Angle up to which the
vehicle bottoms with the underbody on the ramp edge.Fall lineThis is the vertical drop
route.ArticulationThe articulation capability of the vehicle when driving over objects with just one
side of the vehicle.
Checklist before driving offroad
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 offroad:

Obtain sufficient information before driving into offroad terrain with the vehicle.

Do not plan day stages that are too long. Take increased fuel consumption for offroad driving into
account.

Fill up the tank. Fuel consumption is considerably higher offroad.

Check that your tyres are suitable for the offroad journey you have planned. Recommendation for
difficult offroad terrain: always have offroad tyres fitted to your vehicle.

Check the tyre pressure on all tyres and correct if necessary. This includes the temporary spare
wheel, if present.

Check engine oil level and refill engine oil as necessary. The engine will be supplied with engine oil
when it is driven on or across a slope only 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 or rear. It is not always possible to fit the towing eye when the vehicle
is stuck.

Check the vehicle toolkit and add tools according to individual requirements Useful accessories for
offroad driving.

Stow luggage in the vehicle as evenly and as low as possible. Secure all loose items.
Before driving offroad, Volkswagen recommends attending an offroad driving course, particularly if
you have no or very little experience.

Do not slip the clutch or rest your foot on the clutch when driving offroad. When travelling over
uneven ground, you could press the clutch by mistake and lose control of the vehicle. This also
prevents power being transferred between the engine and the gearbox. In addition, driving with the
clutch partially engaged causes premature wear to the clutch lining.
Useful accessories for offroad 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 offroad driving. If
you have an instruction manual or fitting instructions for these accessories, you should always take
them with you and observe them as necessary when driving offroad.
Checklist
Useful items when driving offroad:

Water, compass, maps and torch with spare batteries.

Winch, tow bar or rope with sufficient strength.

Mobile telephone, shovel, blankets and rubber boots.

Electrical 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 can be used 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.
Changing gear correctly
First read and observe the introductoryinformation and safety warnings⇒Introduction 
The correct choice of gear depends on the offroad terrain.
Before attempting to drive through difficult terrain it can be helpful to stop and consider which gear
you should select. After several trips offroad, you will learn which gear to select in conjunction with
the step-down ratio and differential locks for different types of terrain.
General rules

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 offroad 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, drive with Tiptronic in the positions 3 or
2⇒ DSG® dual clutch gearbox .
Use the offroad display ⇒ Offroad display .
Driving on rough terrain
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Use the offroad driving profile ⇒ Setting a driving profile .
You should drive through rocky terrain at no faster than walking pace.
If you are not able to drive around a rock, drive carefully onto the rock with one front wheel and
drive over it slowly ⇒ .

NOTICE
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 available ground clearance 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 hollow 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.

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 offroad .
