Volkswagen Touareg (2015 year). Instruction — part 29

any requirement for engaging Hill Hold is no longer met while the vehicle is stopped, Hill Hold disen-
gages, the indicator light in the button goes out, and the brakes are automatically released and will no
longer hold the vehicle.

Hill Hold is activated automatically when points 1 to 3 are met at the
same time:

1.

Hold the stopped vehicle on an incline with the foot brake or elec-
tronic parking brake.

2.

The engine is running “smoothly”.

3.

The transmission must be in Drive (D) or Sport Drive (S) and the
foot brake must be depressed to keep the vehicle from moving.

4.

To drive off, take your foot off the brake pedal and gently depress
the accelerator within 2 seconds.

Release the brake as you gently depress the accelerator.

Hill Hold is immediately deactivated:

If any requirement listed in the table above is no longer met (see

⇒ table on page 453).

If the engine is not running smoothly or the engine malfunctions.
If the engine stalls or is switched off.
If the transmission is in Neutral (N).

If a tire does not have enough road contact (such as when the vehicle is tipped or at an angle).

WARNING

The intelligent technology of Hill Hold cannot overcome the laws of physics. Never let the
increased convenience provided by Hill Hold tempt you into taking risks.

The Hill Hold feature cannot hold the vehicle in all hill start situations (for example, if the

surface is icy or slippery).

Hill Hold can only help keep the vehicle from moving for less than 2 seconds. After that,

the brakes will be released and the vehicle can roll down the hill.

Hill Descent Assist

Please first read and note the introductory information and heed the WARNINGS

Hill Descent Assist helps the driver on steep downhill grades by actively braking the vehicle. The

vehicle is held to the speed it has when Hill Descent Assist first begins to work

⇒ .

One requirement for speed regulation is that the tires must have a sufficiently good grip on the ground
underneath. For example, Hill Descent Assist cannot perform its function on icy slopes or on slopes
with an oily road surface.

An indicator light comes on in the instrument cluster display whenever Hill Descent Assist is ena-
bled. The indicator light blinks when Hill Descent Assist is regulating the brakes.

Hill Descent Assist is always enabled, but only regulates the brakes when certain requirements are
met.

Hill Descent Assist regulates automatically:

If the vehicle is in off-road mode and the indicator light is on.
And: If your speed is under 18 mph (30 km/h).
And: If the downhill grade is 10 % or steeper.
And: If you neither accelerate nor apply the brakes.
And: If the vehicle's engine is running.

If you accelerate or step on the brake when Hill Descent Assist is operating, the feature switches off.
Hill Descent Assist begins regulating speed again the next time the requirements are met.

Hill Descent Assist does not regulate speed:

On downhill grades of less than 10 %.
OR: At speeds over 18 mph (30 km/h).
OR: If the driver brakes or accelerates.

WARNING

Always be ready to apply the brakes. Otherwise accidents and injuries can occur.

Hill Descent Assist is merely a driving aid and cannot always slow the vehicle down

enough under on downhill grades.

The vehicle may pick up speed despite the use of Hill Descent Assist.

The Hill Descent Assist also works when you are backing down a hill.

Cruise Control System (CCS)

Introduction

In this section you’ll find information about:

Warning and indicator lights

Warning and indicator lights

Cruise control operation

The Cruise Control System (CCS) helps maintain an individually stored constant speed when driving
above about 12 mph (20 km/h).

The CCS slows down the vehicle only by reducing the flow of fuel to the engine, not by braking

⇒ .

More information:

Shifting
Parts, accessories, repairs and modifications

WARNING

Using the cruise control when it is not possible to drive safely at a constant speed can be
dangerous and can lead to an accident and serious personal injury.

Never use cruise control when driving in heavy or varying traffic or when you cannot keep

a safe distance between you and the vehicles, ahead of you.

Never use cruise control on steep, winding, or slippery roads (such gravel roads, wet

roads, or snowy or icy roads) or on roads with standing water.

Never use cruise control when driving off-road or on unpaved roads.
Always adjust your speed and the distance you keep between you and the vehicles ahead

of you to the road, traffic, weather, and visibility conditions.

To help prevent unintended operation of cruise control, switch the system off when it is

not being used.

It is dangerous to use the Resume feature when the previously set speed is too high for

the existing road, traffic, or weather conditions.

When traveling downhill, the cruise control may not be able to maintain a constant speed.

The vehicle will speed up because of its own weight. Downshift and/or use the foot brake to
slow the vehicle.

Adaptive Cruise Control (ACC) with Front Assist

Introduction

In this section you’ll find information about:

Display, warning and indicator lights

Radar sensors, ultrasonic sensors and Front Assist camera

Switching ACC on and off

When to temporarily deactivate Adaptive Cruise Control (ACC)

Forward Collision Warning system (Front Assist)

Temporarily switch off the Forward Collision Warning system (Front Assist) in the following
situations

Forward Collision Warning system (Front Assist) system limits

Autonomous Emergency Braking

Special driving situations

The Adaptive Cruise Control system (ACC) helps maintain an individually stored constant speed
between about 20 mph (30 km/h) and 95 mph (150 km/h) and a previously set distance in time inter-
vals between your vehicle and those in front of you.

ACC uses radar, ultrasonic and video sensors installed on your vehicle. Moving vehicles in front of
yours can be detected within a distance of up to 590 ft (180 m).

The vehicle may be braked, if the situation so requires, to a standstill by an active braking maneu-

ver

⇒ .

Adaptive Cruise Control has system-specified limits. As a driver, you must control the speed and the
distance to other vehicles under some circumstances. If that is necessary, the system requests the
driver to take over using a visual and audible warning.

How does Adaptive Cruise Control (ACC) work?

Adaptive Cruise Control requires you to set the desired speed and distance. Set and adjust the speed
using the lever to the left of the steering column. Set the distance using the sliding switch on top of the
lever.

Driver intervention warning

Adaptive Cruise Control has system-specified limits. As a driver, you must control the speed and the
distance to other vehicles under some circumstances. If that is necessary, the system requests the

driver to take over using a visual and audible warning

⇒ table on page 461, even if the vehicle can be

braked to a standstill by an active braking maneuver.

WARNING

Always remember that the Adaptive Cruise Control has limits – Using Adaptive Cruise Con-
trol when it is not possible to drive safely at a constant speed can be dangerous and can lead
to an accident and serious personal injury.

Adaptive Cruise Control will not slow the vehicle down or maintain the set distance when

you drive towards an obstacle or something on or near the road that is not moving, such as
vehicles stopped in a traffic jam, a stalled or disabled vehicle.

Always adjust your speed and the distance you keep between you and the vehicles ahead

of you to the road, traffic, weather, and visibility conditions.

Never use Adaptive Cruise Control on steep, winding, or slippery roads (such gravel

roads, wet roads, or snowy or icy roads) or on roads with standing water.

Never use Adaptive Cruise Control when driving in heavy or varying stop-and-go traffic.
Never use Adaptive Cruise Control when driving off-road or on unpaved roads.
Always remember that the Adaptive Cruise Control cannot detect a vehicle that is driving

towards you in your traffic lane and that it cannot detect narrow vehicles such as motorcy-
cles and bicycles.

Never follow a vehicle so closely that you cannot stop your vehicle safely. The Adaptive

Cruise Control cannot slow or brake the vehicle safely when you follow another vehicle too
closely. Always remember that the Adaptive Cruise Control has a braking power that is only
about 30% of the vehicle's maximum braking ability, under certain circumstances the auto-
matic braking function cannot bring the vehicle to a stop in time.

Always turn off Adaptive Cruise Control when entering turn lanes, exit lanes and construc-

tion zones or in similar situations because the vehicle will automatically accelerate to the
stored speed when the road ahead is clear.

To help prevent unintended operation of Adaptive Cruise Control, switch the system off

when it is not being used.

It is dangerous to use the Resume feature when the previously set speed is too high for

the existing road, traffic, or weather conditions.

When traveling downhill, the Adaptive Cruise Control may not be able to maintain a con-

stant speed. The vehicle will speed up because of its own weight. Downshift and/or use the
foot brake to slow the vehicle.

Never allow the closing speed between you and other vehicles to be so high that the

Adaptive Cruise Control may not be able to slow your vehicle safely. If closing speed is too
high, you must apply the brakes yourself to reduce the risk of a rear-end crash.

If a driver intervention warning appears in the instrument cluster display, immediately

takeover the control of the brake and gas pedals and low down the vehicle or bring it to stop
when necessary and according to the traffic situation.

If a Forward Collision Warning system (Front Assist) collision warning appears in the

instrument cluster display, immediately takeover the control of the brake and gas pedals and
low down the vehicle or bring it to stop when necessary and according to the traffic situation.

Always be prepared to takeover the control of the brake and the gas pedal in every situa-

tion.

NOTICE

If you suspect that ACC and the Forward Collision Warning system (Front Assist) don't work
properly or the sensors are damaged, switch off ACC immediately.

Go see an authorized Volkswagen dealer or Volkswagen Service Facility for assistance and

have the ACC system checked.

NOTICE

If you notice that Adaptive Cruise Control (ACC) or Front Assist doesn't work properly or the
sensors are damaged, switch off ACC immediately.

Go see an authorized Volkswagen dealer or Volkswagen Service Facility for assistance and

have the ACC system checked.

The sensors can be damaged or become misaligned in low speed impacts and parking

maneuvers. Damaged or misaligned sensors can cause ACC or Front Assist to malfunction.

To help make sure that the system works properly, always keep the sensors clean, free of

snow and ice; do not cover the sensors with stickers or other objects.

When cleaning the sensors with power washers or steam cleaners, only spray the sensors

directly for a very short time, and always keep the washer nozzle at least 4 inches (10 cm) from
the sensors.

Requirements for activating ACC

Lever is in the

(1)

position.

The selector lever must be in D, S or in Tiptronic mode.
Gradient angles can't be more than +/- 19 %.
Brake pedal is depressed when vehicle is standing still.
the driver safety belt is fastened.
The doors and the engine hood are closed.
The electronic parking brake is released
Hill Descent Assist is not activated.
The vehicle is not rolling backwards.
There is no parked vehicle or other object in front of your moving vehicle.

Activating ACC

When ACC is active one of the 2 green indicator lights ( or ) light up and the set speed is shown in
the display of the instrument cluster and indicated by red dots on the speedometer. Text messages

and indicator lights in the instrument cluster inform you about the status of the system

⇒ page 459.

When ACC is switched, activated and properly working, it will store and regulate the desired speed.
The set speed can vary from the actually driven speed if ACC is regulating the distance to the vehicle
travelling ahead.

Decelerating to a stop

If a vehicle ahead decelerates to a stop the Adaptive Cruise Control likewise decelerates your vehicle
to a standstill. After this vehicle is kept in place by the brakes.

In this state using the brake does not deactivate the Adaptive Cruise Control.

If you unlock the safety belt, open the a door or the engine hood, switch off the ignition during such a
braking state or if the stop exceeds about three minutes, the Adaptive Cruise Control switches off
temporarily and activates the parking brake.

By depressing the gas pedal while the vehicle is standing still and ACC is active, the vehicle will ac-
celerate. Once you take your foot off the pedal, ACC will automatically resume the stored speed and
regulate the set distance.

ACC will not automatically accelerate if the vehicle ahead accelerates.

Distance (time interval) to the vehicle ahead and driving profiles

The distance the ACC maintains to the vehicle traveling ahead is determined by time intervals. A time
distance to the vehicle traveling ahead is maintained. This results in a speed-dependent distance. The

higher the speed, the larger the distance in feet/meters

⇒ .

The distance can be set at 4 different levels:

Distance

Time distance at 65 mph
(105 km/h)

Very small

about 1,0 Seconds

Small

about 1,3 Seconds

Medium

about 1,8 Seconds

Large

about 2,5 Seconds

Besides changing the time distance, the acceleration characteristics can be changed, by choosing on
of the following driving profiles:

Comfort
Normal
Sport

The distance intervals can be set by pushing the slider switch on the lever

⇒

fig. 273

. The driving

profile can only be set in the infotainment system .

Always select a greater following distance to the vehicle ahead on wet roads than on dry roads.

DANGER

Following other vehicles too closely increases the risk of collisions and serious personal
injury or even death.

Always obey applicable traffic laws when setting the distance to the vehicles ahead in

traffic.

Setting short distances to the traffic ahead reduces the time and distance available to

bring your vehicle to a safe stop and makes it even more necessary to pay close attention or
traffic.

Always use good judgment and select a safe following distance for the traffic, road and

weather conditions.

Never use Adaptive Cruise Control on narrow or winding roads or under poor road condi-

tions (snow, ice, streets covered with standing water or gravel, for example) or when visibility
is poor, especially when it is foggy.

Always select a greater following distance to the vehicle ahead on wet roads than on dry

roads.

WARNING

Improper use of the Adaptive Cruise Control can cause collisions, other accidents and seri-
ous personal injury.

Always remember that the Adaptive Cruise Control has limits – it will not slow the vehicle

down or maintain the set distance when you drive towards an obstacle or something on or
near the road that is not moving, such as vehicles stopped in a traffic jam, a stalled or disa-
bled vehicle.

Always remember that the Adaptive Cruise Control cannot detect a vehicle that is driving

towards you in your traffic lane and that it cannot detect narrow vehicles such as motorcy-
cles and bicycles.

Never drive at speeds that are too fast for traffic, road and weather conditions.
Never follow a vehicle so closely that you cannot stop your vehicle safely. The Adaptive

Cruise Control cannot slow or brake the vehicle safely when you follow another vehicle too
closely. Always remember that the Adaptive Cruise Control has a braking power that is only
about 30% of the vehicle's maximum braking ability, the automatic braking function cannot
bring the vehicle to a stop.

Never use Adaptive Cruise Control when you cannot drive safely at a steady speed, in-

cluding on city streets, on winding roads or when road conditions are poor (for example, on
ice, gravel, in fog, heavy rain or on wet roads that increase the risk of hydroplaning).

The radar sensor's vision can be reduced by rain, snow and heavy road spray. These and

similar conditions can prevent vehicles up ahead from being accurately detected and in some
cases they may not be detected at all. Do not use ACC when the radar sensors cannot accu-
rately detect vehicles moving ahead of you in traffic.

Always turn off Adaptive Cruise Control when entering turn lanes, exit lanes and construc-

tion zones or in similar situations because the vehicle will automatically accelerate to the
stored speed when the road ahead is clear.

Never rest your foot on the accelerator pedal, especially when the Adaptive Cruise Control

is being used because doing so will override the braking function.

Always pay attention to traffic, especially when Adaptive Cruise Control is switched on.
Always maintain a safe speed and distance between your vehicle and other vehicles while

considering the traffic situation. This is the duty of the driver. Adaptive Cruise Control is
merely an aid to the driver.

To prevent unintended operation, always switch ACC off when it is not being used.
It is dangerous to use the “Resume” feature when the previously set speed is too high for

existing road, traffic or weather conditions.

Always select a speed and distance to traffic ahead that is safe and appropriate under the

prevailing traffic, road, weather and lighting conditions.

Never allow the closing speed between you and other vehicles to be so high that the

Adaptive Cruise Control may not be able to slow your vehicle safely. If closing speed is too
high, you must apply the brakes yourself to reduce the risk of a rear-end crash.

NOTICE

When the vehicle is driving at speeds lower than 20 mph (30 km/h) and the

button is pressed

or the lever is moved to

, the vehicle will be accelerated to the lowest possible speed that

can be set in ACC of 20 mph (30 km/h)

The stored speed is canceled when the ignition or the ACC is switched off.
