persons could lock the vehicle, start the engine, switch on the ignition or operate electrical
equipment such as the electric windows.

Before leaving the vehicle, always switch off the ignition manually and observe any information
shown on the instrument cluster display.

Leaving the vehicle stationary for long periods with the ignition switched on can discharge the 12-
volt vehicle battery so that the engine can no longer be started.
Starting the engine

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.

Deactivate the start/stop system manually.
Go to a qualified workshop immediately.
Manual gearbox: selecting a gear

Fig. 103 Gear shift pattern of a 5-speed manual gearbox.

Use fast acceleration only if visibility, weather, road and traffic conditions permit, and other road
users are not put at risk due to the acceleration and driving style.
Always adjust your driving style in accordance with the flow of traffic.
When the TCS is switched off, the drive wheels may spin, especially if the road surface is wet,
slippery or dirty. This may result in you no longer being able to steer or control the vehicle.

WARNING
When the engine is running, the vehicle will start to move as soon as a gear is engaged and the
clutch is released. This also applies when the electronic parking brake has been switched on.
Never engage reverse gear while the vehicle is in motion.

WARNING
Shifting gears incorrectly to gears that are too low can lead to a loss of control over the vehicle, with
accidents and serious injuries as a consequence.

NOTICE
Serious damage to the clutch and gearbox could occur if the gear lever of the manual gearbox is
shifted to a gear which is too low when travelling at high speeds or at high engine speeds. This also
applies if the clutch remains depressed and the gears do not engage.

NOTICE
Please note the following points in order to avoid damage and premature wear:
Do not rest your hand on the gear lever when driving. The pressure from your hand is passed onto
the selector forks in the gearbox.
Ensure that the vehicle has come to a full stop before engaging reverse gear.
Always fully depress the clutch pedal when changing gear.
Do not hold the vehicle by riding the clutch on uphill gradients with the engine running.

Changing up a gear early will help to save fuel and minimise engine noise.
Troubleshooting
Clutch slipping

If the text message and signal tone are repeated approximately every 10 seconds, park the vehicle
safely as soon as possible and switch the engine off. Allow the gearbox to cool down.
Do not drive on until the signal tone stops in order to avoid damage to the gearbox. You should not
pull away or drive the vehicle at very low speeds while the gearbox is overheated.
Downhill speed control
The downhill speed control system helps when braking and travelling downhill in vehicles with a
DSG® dual clutch gearbox ⇒ . The downhill speed control uses the braking power of the engine.
The DSG® dual clutch gearbox selects the best gear depending on the steepness of the gradient and
the current speed. The selector lever must be in position D/S. The downhill speed control is not
active in Tiptronic mode.
As the downhill speed control can shift down only as far as third gear, it may be necessary to activate
the Tiptronic mode when driving down particularly steep inclines. When in Tiptronic mode, select
second or first gear manually in order to make use of the braking effect of the engine and to relieve
the load on the brakes.
The start/stop system is automatically deactivated as long as downhill speed control is active.
Activating downhill speed control automatically:
If the downhill gradient is greater than approximately 6%.
AND: if the selector lever is in position D/S.
In addition, if the cruise control system or Adaptive Cruise Control (ACC) is switched off: if the
vehicle speed is less than approximately 80 km/h (50 mph) or the brake pedal is depressed.
In addition, if the cruise control system or Adaptive Cruise Control (ACC) is active: if the stored speed
is exceeded.
Deactivating downhill speed control automatically:
If the downhill gradient becomes less steep.
OR: if the gearbox shifts up a gear because the engine speed is higher than approximately 4,500 rpm.
Or additionally if the cruise control system or Adaptive Cruise Control (ACC) is active: if the stored
speed can be maintained.

WARNING
The intelligent downhill speed control technology cannot overcome the laws of physics, and
functions only within the limits of the system. Never let the extra convenience afforded by pull-away
assist systems tempt you into taking any safety risks when driving.
Unintentional vehicle movements can cause serious injury.
The downhill speed control cannot replace the full concentration of the driver.
Always adapt your speed and driving style to suit visibility, weather, road and traffic conditions.

An incorrect tyre pressure can cause overheating, sudden tyre damage including tyre bursts and
ripping of the tread surface and thus to a loss of control over the vehicle.
Driving on steep terrain
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Driving uphill or downhill
Get out of the vehicle and assess the situation before you attempt to drive up or down a hill:
Walk along the section and check the firmness of the ground. Look out for obstacles and other
hidden dangers ⇒ .
Check the section beyond the hill.
You should not follow the route if it is too steep, uneven or if the ground surface is too loose. Select
another route.
Drive slowly and at constant speed straight up or down a slope.
Accelerate only to the speed you need to climb the slope. Too much acceleration can cause the
wheels to spin and lead to a loss of control of the vehicle. Insufficient throttle increases the
probability of stalling the engine.
Never attempt to stop or turn on a slope.
Avoid allowing the engine to stall.
Do not change gear or engage the clutch when climbing a slope.
Use the offroad display ⇒ Offroad display .
If you cannot continue to drive up a hill
Never turn the vehicle around on an uphill gradient.
If the engine has stalled, depress the footbrake and start the engine again.
Select reverse gear and reverse back slowly in a straight line.
Use the foot brake to keep a constant speed until you have reached a safe place.
Driving downhill
Never exceed the tilt angle of the vehicle! If, in an emergency, you have to traverse the slope when
driving down it and the vehicle threatens to tip over, steer into the fall line immediately.
There is an increased risk of rolling over when driving downhill. Concentrate on steering the vehicle
when driving downhill in particular.
Use the offroad display on steep downhill stretches ⇒ Offroad display .
Drive down steep inclines in first gear.
Use the foot brake sparingly in order not to lose control of the vehicle.
