Driving on hills
The steeper the grade, the lower the gear that must be selected. Lower gears increase the braking
effect of the engine. Never coast downhill in Neutral (N).
x Reduce speed.
x Switch to Tiptronic mode by moving the selector lever from Drive (D) to the right into the Tiptronic
position
x Downshift by pulling the selector lever back briefly (-).
x OR: Downshift using the paddles on the steering wheel
If you stop and start up again when going uphill, you should use Hill Hold as long as the engine is
running.
Vehicles without Hill Hold: If you stop on a hill with the vehicle in gear, you must depress the brake
pedal or engage the parking brake to keep the vehicle from rolling. Do not release the brake pedal or
the parking brake until the vehicle has started to move forward ⇒ .
Kick-down acceleration
The kick-down feature permits maximum acceleration when the selector lever is in the Drive (D), Sport
Drive (S) or Tiptronic mode.
If you push the accelerator all the way down, the vehicle will automatically downshift, depending on
vehicle speed and engine speed (rpm). This feature lets you take advantage of the full acceleration
capacity of the vehicle ⇒ .
With kick-down actuated, the transmission will stay in the current gear longer and not upshift until the
engine reaches maximum rpm.
WARNING
Rapid acceleration can cause skidding and loss of traction, especially on slippery roads,
resulting in a loss of vehicle control, collisions, and serious personal injury.
x Only use the kick-down feature or fast acceleration if visibility, weather, road, and traffic
conditions permit and other drivers will not be endangered by your driving and the vehicle's
acceleration.
x Always adapt your driving to the traffic flow.
x Note that the drive wheels can spin and the vehicle can swerve when ASR is switched off,
especially when the road is slippery.
x Once you have accelerated, switch ASR back on again.
NOTICE
x When stopping on hills with the transmission in a drive gear, do not use the accelerator to
help prevent the vehicle from rolling backwards. This can cause the automatic transmission to
overheat and be damaged.
x Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is
not running. The transmission will not be lubricated and will be damaged.

inputs to help keep the vehicle going in the intended direction. If you are traveling at a speed that
causes you to run off the road before ESC can provide any assistance, you may not experience the
benefits of ESC.
ESC includes and/or works together with the ABS, BAS, ASR, EDL, and XDL systems (see below).
ESC is switched on all the time. In certain situations when you need less traction or additional traction
cannot be achieved, you can switch off ASR by pressing the m button ⇒ fig. 126. Be sure to switch
ASR on again when you no longer need less traction.
Anti-Lock Brake System (ABS)
ABS helps to keep the wheels from locking up and helps to maintain the driver's ability to steer and
control the vehicle. This means the vehicle is less likely to skid, even during hard braking:
x Push the brake pedal down hard and hold it there. Don't take your foot off the pedal or reduce the
force on the pedal!
x Do not “pump” the brake pedal or let up on it!
x Steer the vehicle while pushing down hard on the brake pedal.
x ABS stops working if you release or let up on the brake.
When ABS is doing its job, you will notice a slight vibration through the brake pedal and hear a
noise. ABS cannot shorten the stopping distance under all conditions. The stopping distance may
even be longer, for instance, when driving on gravel or on newly fallen snow covering an icy or
slippery surface.
Brake Assist (BAS)
The Brake Assist System can help to reduce stopping distances. If you press the brake pedal very
quickly, BAS detects an emergency situation. It then very quickly builds up full brake system pressure,
maximizing braking power and reducing the stopping distance. This way, ABS can be activated more
quickly and efficiently.
Do not reduce pressure on the brake pedal! BAS switches off automatically as soon as you release or
let up on the brake.
Anti-Slip Regulation (ASR)
ASR reduces engine power directed to spinning wheels and adjusts power to the road conditions.
Even under poor road conditions, ASR can make it easier to get moving, accelerate, and climb hills.
ASR can be switched on or off manually
Electronic Differential Lock (EDL and XDL)
EDL is applied during regular straight-line acceleration. EDL gently brakes a drive wheel that has lost
traction (spinning) and redirects the drive force to other drive wheels. In extreme cases, EDL
automatically switches off to keep the brake from overheating. As soon as the brake has cooled down,
EDL automatically switches on again.
XDL is an extension of the Electronic Differential Lock system. XDL does not react to drive wheel
slippage when driving straight ahead. Instead, XDL detects slippage of the inside front wheel during
fast cornering. XDL applies enough brake pressure to this wheel in order to stop the slippage. This
improves traction, which helps the vehicle stay on track.

WARNING
Driving fast on icy, slippery, or wet roads can lead to a loss of control and result in serious
personal injury for you and your passengers.
x Always adjust your speed and driving style to road, traffic, weather, and visibility
conditions. Never let the additional safety that ESC, ABS, BAS, ASR, and EDL can provide
tempt you into taking extra risks.
x Braking assistance systems cannot overcome the laws of physics and always prevent
loss of vehicle control. Slippery and wet roads are still dangerous even with ESC and the
other systems!
x Driving too fast on wet roads can cause the wheels to lose contact with the road and
“hydroplane.” A vehicle that has lost road contact cannot be braked, steered, or controlled.
x These systems cannot reduce the risk of accident, for example if you drive too fast for
conditions or if you do not keep your distance from the vehicle in front of you.
x Although these systems are very effective and can help you control the vehicle in many
difficult situations, always remember that your vehicle handling control is limited by tire
traction.
x When accelerating on a slippery surface, for example on ice and snow, depress the
accelerator carefully. Even with these systems, the wheels may start to spin, leading to a loss
of vehicle control.
WARNING
The effectiveness of ESC can be significantly reduced if other components and systems that
affect vehicle dynamics, including but not limited to brakes, tires, and other systems
mentioned above, are not properly maintained or functioning.
x Always remember that vehicle alterations or modifications can affect the functioning of
the ABS, BAS, ASR, EDL, and ESC systems.
x Changing the vehicle suspension or using an unapproved tire/wheel combination can
change the way the ABS, BAS, ASR, EDL, and ESC systems work and reduce their
effectiveness.
x The effectiveness of ESC is also determined by the tires fitted 273.
All 4 wheels must be equipped with identical tires in order for ESC and ASR to work properly.
Differences in the tread circumference of the tires can cause the system to reduce the engine power
when it is not expected.
If ABS is not working, ESC, ASR, and EDL will also not work.
You may hear noises when these systems are active.

To help make it more difficult to steal your vehicle, you should always make sure the steering column
is locked before leaving the vehicle.
Electronic steering column lock
Vehicles with Keyless Access: The steering column is locked if the driver door is opened with the
ignition switched off. The vehicle must be standing still and the transmission must be in Park (P) on an
automatic transmission vehicle.
If the driver door is opened before the ignition is switched off, the electronic steering column lock is
activated only after the vehicle has been locked with the vehicle key or via the sensor in the door
handle.
Mechanical steering column lock
Vehicles without Keyless Access: The steering column is locked if the vehicle is stationary and the
vehicle key is removed from the ignition switch.

Engaging the steering column
lock
Disengaging the steering column
lock
Parking the vehicle Turn the steering wheel slightly to
take pressure off the steering
column lock.
Remove the vehicle key. Insert the vehicle key into the
ignition switch.
Turn the steering wheel slightly until
you hear the steering column lock
engage.
Hold the steering wheel in this
position and turn the ignition switch.

Power steering
Power steering automatically adjusts to driving speed, steering torque, and the steering angle of the
wheels. Power steering works only when the engine is running.
If power steering is reduced or lost completely, it will be much harder to steer and control the vehicle.
Counter-steering assistance
Counter-steering assistance is part of Electronic Stability Control (ESC). This feature makes it easier
for the driver to control the vehicle in difficult situations. For example, if you have to brake hard on a
surface that provides uneven traction, the vehicle could pull to the right or left. ESC detects this
situation and helps the driver counter-steer with additional steering power ⇒ .
WARNING
The counter-steering assistance in ESC can do no more than help the driver steer in difficult
situations. The driver must still control the vehicle. The vehicle does not steer by itself with
this feature!
NOTICE
If the ignition is off, the steering column lock will engage and the vehicle cannot be steered.
For this reason, you must leave the ignition on when going through an automatic car wash, for
example, so that the wheels will still steer.

WARNING
New tires or tires that are old, worn or damaged cannot provide maximum control and
braking performance.
x Improper care and handling of tires and wheels can reduce driving safety and cause
accidents and severe injuries.
x Install only radial tires of the same make, the same dimensions (tread circumference), and
similar tread profile on all 4 wheels.
x New tires tend to be slippery and must be broken in. Always drive with special care for the
first 350 miles (560 km) to help reduce the risk of losing control, a collision, and serious
personal injuries.
x Check tire inflation pressure regularly when the tires are cold and always maintain the
prescribed tire pressure. Low tire pressure can cause tires to get too hot, resulting in tread
separation, sudden loss of pressure, and blowouts. Tires with excessively low pressure flex
(bend) more, which can cause the tire to overheat and fail suddenly without warning.
x Check tires regularly for wear and damage.
x Never drive with worn or damaged tires (for example, tires with punctures, cuts, cracks,
blisters, or bumps). Driving with worn or damaged tires can lead to loss of vehicle control,
sudden tire failure including blowouts and sudden deflation, crashes, and serious personal
injuries.
x Have worn or damaged tires replaced immediately.
x Never exceed the maximum speed rating or the maximum load rating of the tires on your
vehicle.
x The effectiveness of the driver assistance systems and the braking support systems
depends on the tire traction.
x If you notice unusual vibration or if the vehicle pulls to one side when driving, always stop
as soon as it is safe to do so and check the wheels and tires for damage.
x To reduce the risk of losing control, crashes, and serious personal injuries, never loosen
the bolts on wheels with bolted rim rings.
x Never mount used tires on your vehicle if you are not sure of their past use. Old, used
tires and wheels may have damage that cannot be seen that can lead to sudden tire failure
and loss of vehicle control.
x Tires age even if they are not being used and can fail suddenly, especially at high speeds,
causing loss of vehicle control, accidents, and severe personal injuries. Tires that are more
than 6 years old can be used only in an emergency and even then only with special care and
at low speed.
For technical reasons it is usually not possible to use wheel rims from other vehicles. Even wheel
rims from the same model may not fit properly. Check with an authorized Volkswagen dealer or
authorized Volkswagen Service Facility if necessary.

Uniform Tire Quality Grading (UTQG): Quality grades can be found where applicable on the tire
sidewall between the tread shoulder and maximum section width. Example:
x Treadwear (number)
x Traction: AA, A, B or C
x Temperature: A, B or C
For example: Treadwear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Requirements in addition to these grades.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under
controlled conditions on a specified government test course.
For example, a tire graded 150 (Treadwear-value 150) would wear one-and-one-half (1 1/2) times as
well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their use, however, and may
depart significantly from the norm due to variations in driving habits, service practices and differences
in road characteristics and climate.
Traction
The traction grades from highest to lowest, are AA, A, B and C. Those grades represent the tire's
ability to stop on wet pavement as measured under controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C may have poor traction performance ⇒ .
Temperature
The temperature grades are A (the highest), B, and C representing the tire's resistance to the
generation of heat, and its ability to dissipate heat when tested under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by law ⇒ .
WARNING
The traction grade assigned to this tire is based on straight-ahead braking traction tests, and
does not include acceleration, cornering, hydroplaning or peak traction characteristics.
WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
