WARNING
The risk of serious injury can be reduced with the engine running or when starting the engine.
Never start or run the engine in unventilated or enclosed spaces. The exhaust fumes contain carbon
monoxide, an odourless and colourless toxic gas. Carbon monoxide can cause people to lose
consciousness. It can also cause death.
Never start or run the engine if oil, fuel or any other highly flammable fluids are under or near the
vehicle, or are leaking out of the vehicle, e.g. as the result of damage.

Never leave the vehicle unattended with the engine running, particularly if a gear or driving position
has been selected. The vehicle could move suddenly or something unexpected may happen that may
cause damage, fire and serious injuries.
Never use a start booster. Start boosters could explode and cause the engine to suddenly run at high
revs.

WARNING
Never leave the engine running if you leave the vehicle unattended, particularly if a gear or position
has been selected. The vehicle could move suddenly or something unexpected may happen that may
cause damage, fire or serious injuries.

WARNING
Start boosters could explode or cause the engine to suddenly run at high revs.
Never use a start booster.

NOTICE
The starter and the engine can be damaged if you attempt to start the engine while the vehicle is in
motion or if the engine is started again immediately after it has been switched off.
When the engine is cold, avoid high engine speeds, driving at full throttle and overloading the
engine.
Do not push start or tow start the vehicle. Unburnt fuel could damage the catalytic converter.

NOTICE
If the engine does not start, never use the starter with a gear selected and the vehicle key in the
ignition lock in position ⇒ Fig. 99②  for driving or tow-starting, e.g. when the fuel tank is empty.
This could cause damage to the starter.
Fill up with fuel if necessary ⇒ Fuel types and refuelling  or jump start the vehicle ⇒ Jump starting .
If the engine does not start, seek expert assistance.

Do not warm up the engine by running it while the vehicle is stationary. Instead, pull off as soon as
there is good visibility through the windows. This helps the engine reach operating temperature
faster and reduces emissions.

Components with a high power consumption are switched off temporarily when the engine is
started.

The engine cannot be started with the starter button, for example, if the button cell in the vehicle
key is weak or flat. In this case, use the emergency start function ⇒ No valid vehicle key recognised .

When starting from cold, the engine may be a little noisy for the first few seconds. This is quite
normal, and no cause for concern.

At outside temperatures of less than +5°C (+41°F), fumes may be detected under a vehicle with a
diesel engine if the fuel-powered supplementary heater is switched on.

when opening the driver door and corresponding warning messages appear on the display of the
instrument cluster.
Warning before leaving the vehicle
Vehicles with DSG dual clutch gearbox: if the selector lever is not in position P, an acoustic
warning signal will sound when the driver door is opened and the warning message Please move
selector lever to position P. will be shown on the instrument cluster display. In this way, a warning is
given that the vehicle could potentially roll away. When you leave the vehicle, the electronic parking
brake also switches on to prevent the vehicle rolling away.

WARNING
Never switch off the engine while the vehicle is in motion. This can lead to a loss of vehicle control,
accidents and serious injuries.

The airbags and belt tensioners will not work if the ignition is switched off.
The brake servo will not work when the engine is switched off. More force is required on the brake
pedal to stop the vehicle.
If the vehicle key is removed from the ignition, the steering lock may activate and you will no longer
be able to steer the vehicle.

WARNING
The components of the exhaust system become very hot. This can cause fires and serious injuries.
Never park the vehicle so that parts of the exhaust system can come into contact with any
inflammable material underneath the vehicle, e.g. undergrowth, leaves, dry grass, spilt fuel etc.
Never apply additional underseal or anti-corrosion coatings to the exhaust pipes, catalytic
converters, heat shields or particulate filter.

NOTICE
If the vehicle has been driven at high load for a long period, the engine can overheat when it is
switched off. In order to avoid damage to the engine, allow the engine to run in neutral position for
approximately 2 minutes before switching it off.

After the engine is switched off, the radiator fan in the engine compartment may run on for some
minutes, even if the ignition is switched off or the vehicle key has been removed. The radiator fan
will switch itself off automatically.
Electronic immobiliser
The immobiliser helps to prevent the engine from being started and driven with an unauthorised
vehicle key.
There is a chip in the vehicle key. The immobiliser is automatically deactivated by this when a valid
vehicle key is inserted in the ignition lock.
The electronic immobiliser is automatically activated when the vehicle key is removed from the
ignition lock. In vehicles with Keyless Access, the vehicle key must be outside the vehicle.
The engine can be started only using a Volkswagen Genuine vehicle key with the correct code.
Coded vehicle keys are available from a Volkswagen dealership.

Problem-free operation of the vehicle is guaranteed only with Volkswagen Genuine vehicle keys.

The downhill speed control cannot hold the vehicle on the gradient in all situations or brake it
sufficiently on all slopes going downhill (e.g. if the ground is slippery or icy).

WARNING
Always be prepared to brake the vehicle. Accidents and injuries could occur if you are not prepared
to brake.
The downhill speed control is only a support function and may not be able to brake the vehicle
sufficiently in all situations when driving downhill.
The vehicle may become faster despite the downhill speed control being in operation.
Steering
Information on steering
The steering should be locked every time you leave the vehicle to make it more difficult for the
vehicle to be stolen.
The steering
The power steering is not hydraulic, but is an electromechanical system. The advantage of this
steering system is that no hydraulic hoses, hydraulic oil, pumps, filter or other parts are required.
The electromechanical system reduces fuel consumption. A hydraulic system requires constant oil
pressure in the system, whereas an electromechanical steering system only needs an energy supply
while steering.
In vehicles with driving profile selection, the selected driving profile can affect the behaviour of the
power steering ⇒ Driving profile selection and 4MOTION Active Control .
Electronic steering column lock in vehicles with a starter button
The steering column will be locked if the driver door is opened when the ignition is switched off. For
this, the vehicle should be stationary and, if necessary, the gear selector lever should be in position
P.
If the ignition is not switched off until after the driver door is opened, the electronic steering column
will only be locked when the vehicle is locked using the sensor in the door handle or the vehicle key.
Mechanical steering column lock (steering lock) in vehicles with an ignition lock
The steering column is locked if the vehicle key is removed from the ignition lock when the vehicle is
stationary. Turn the steering wheel slightly until the steering lock audibly engages.
Insert the vehicle key into the ignition lock to unlock the steering lock. Turn the steering wheel
slightly to relieve the load on the steering lock mechanism. Hold the steering wheel in this position
and turn the ignition on.
Electromechanical steering

When the ignition is switched off, the set driving profile and the individual settings will remain
selected.
Vehicles with all-wheel drive: if the Snow, Offroad or Offroad Individual driving profile was
selected last, the onroad driving profile that was last active will be activated after the ignition has
been switched off for a long period.
Vehicles without starter button: as soon as the vehicle key is removed from the ignition lock.
Vehicles with starter button: as soon as the driver door is opened when the ignition is switched
off.
Sport functions: select Sport driving profile again.
OR: tap the selector lever of the DSG® dual clutch gearbox backwards to the position S⇒ DSG® dual
clutch gearbox .
Eco functions: select Eco driving profile again.
