4MOTION
®
An all-wheel-drive system that provides the best possible
traction at all road speeds, in all weather and road conditions.
An electronic Haldex clutch responds to traction losses at the
front and rear axles and directs torque to the axle with the
best traction.
Adaptive Chassis Control
The electrically controlled dampers of adaptive chassis
control constantly adjust to the road conditions, the driving
situation and driver’s requirements. Using a button located on
the centre console, the driver selects between three damper
settings – NORMAL, COMFORT and SPORT.
Starting from the normal setting, the driver can change the
basic character of the car towards sporty or more comfort-
oriented driving. In SPORT and COMFORT settings, the
corresponding name is illuminated in the button. In NORMAL
setting, only the shock absorber symbol is illuminated. In all
settings, the adaptive chassis control adjusts the damping to
the particular driving situation (up till one thousand times
per second) which means it offers an optimum level of driving
comfort and enjoyment at all times. In addition, in the SPORT
setting the steering feel is also adapted. Particularly on windy
roads and poor surfaces, using adaptive chassis control offers
sporty and yet comfortable driving.
Adaptive Cruise Control (ACC)*
Adaptive Cruise Control (ACC) is an extension of the
conventional cruise control system with advanced capabilities
based on a radar sensor. When ACC is activated, the vehicle
automatically brakes and accelerates in a speed range set by
the driver.
If the Passat CC approaches a slower vehicle, the ACC brakes
the car to the same speed and maintains the pre-selected
distance. Even when a vehicle pulls into the same lane in front
of you or slows, your vehicle is automatically decelerated to
the pre-selected distance. If the vehicle ahead moves out of
your lane, the Passat CC then accelerates up to the preset
desired speed.
Deceleration of the vehicle may take place via intervention
in the engine management system. If deceleration via engine
torque is not suffi cient, brake intervention takes place,
braking the vehicle to a standstill if the traffi c situation
necessitates. ACC can be reactivated automatically by tapping
the accelerator pedal.
Adaptive Cruise Control (ACC) cannot replace the driver’s assertiveness. The driver
is still legally responsible for the vehicle and must monitor the speed and distance in
relation to other vehicles. The ACC system does not react to stationary obstacles and
oncoming vehicles. The ACC system should not be used on winding roads or in adverse
weather conditions such as heavy rain.
Anti-lock Braking System (ABS)
When braking, wheel speed sensors measure the road wheel
speed and should one or more wheels start to lock the ABS
system reduces brake pressure to that wheel. This prevents
the wheels from locking during heavy or emergency braking,
enabling the vehicle to remain steerable.

Anti-Slip Regulation (ASR)
ASR improves driving and steering characteristics by
preventing the driven wheels from spinning under
acceleration. When a difference in driving wheel speed is
detected (i.e. when one wheel starts to spin due to differences
in road surfaces, e.g. due to water or dirt) the system
automatically reduces engine torque. ASR is a switchable
traction control system.
Auto Hold Function
As soon as the vehicle comes to a complete stop, the ABS
hydraulic unit stores the vehicles fi nal braking pressure. So
even when you take your foot off the brake pedal, all four
wheels brakes remain applied, providing increased comfort
in stationary traffi c. This function is released automatically
when you drive off again.
Brake Assist
During emergency braking, Brake Assist aids the driver
by increasing the brake pressure automatically to a level
exceeding the locking limit. The ABS is thus quickly brought
into the operating range, which enables maximum vehicle
deceleration to be achieved.
Direct Shift Gearbox (DSG)
DSG is a manual gearbox in which the gearshifts are
controlled electronically. What makes the DSG unique is
that it has 2 separate gear sets operated by 2 wet multi-plate
clutches. The benefi t of 2 gear sets and 2 multi-plate wet
clutches is that one gear set and clutch is engaged driving the
vehicle with the second clutch having already pre-selected the
next gear awaiting for power to be transferred. As the next gear
has already been pre-selected prior to power being applied,
the gear change only takes 3-4 100ths of a second. There is
virtually no interruption to power, traction or acceleration.
The DSG also offers Tiptronic gear selection and sports mode.
Electronic Brake-pressure Distribution (EBD)
Electronic, more sophisticated means of regulating the ratio
of front/rear brake pressure. Settings are varied according to
driving and load conditions to ensure each wheel is braked to
the optimum extent.
Electronic Diff erential Lock (EDL)
EDL improves driving and steering characteristics when
accelerating on road surfaces where each wheel has a different
degree of traction. The system operates automatically and
is combined with the ABS system. Using the ABS wheel
sensors, EDL monitors the speed of the individual driving
wheels. When a difference in driving wheel speed is detected
(i.e. when one wheel starts to spin due to differences in road
surfaces, e.g. due to water or dirt) the system brakes the
spinning wheel, transferring engine power to the wheel with
the best traction.
