Volvo XC70 (2016 year). Manual — part 14

•

Lane Departure Warning (LDW), see

When one or both of the functions has been

switched on, it is in standby mode and is acti-

vated when the vehicle exceeds a speed of

40 mph (65 km/h).
The function deactivates if the vehicle's

speed goes under 37 mph (60 km/h).
Both functions use a camera that is depend-

ent on the road/lane being clearly marked by

painted lines on each side.

WARNING

The Driver Alert System does not function

in all situations and is designed to be a

supplementary aid. It is not, however,

intended to replace the driver’s attention

and judgement.

Driver Alert Control (DAC) –

introduction

DAC is intended to alert the driver if his/her

driving becomes erratic, such as if the driver

is distracted or fatigued.

DAC is designed to help detect a slowly

changing driving pattern. It is primarily

intended to be used on main roads and is not

meant for use in city traffic.

A camera monitors the painted lines marking

the lane in which the vehicle is traveling and

compares the direction of the road with the

driver’s movements of the steering wheel.

The driver is alerted if the vehicle does not

follow the lane smoothly.

Adaptive Cruise Control – limitations

The camera has certain limitations, see

(p. 193).

WARNING

•

DAC is not intended to extend the

duration of driving. Always plan breaks

at regular intervals to help remain alert.

•

A warning from DAC should not be

ignored. A driver may not be aware of

how fatigued he/she has become.

•

In certain cases, fatigue may not affect

the driver’s behavior. In situations of

this type, no warning will be provided.

Therefore, it is important to take

breaks at regular intervals, regardless

of whether or not DAC has given a

warning.

Driver Alert Control (DAC) – function

Function
Driver Alert is activated when the vehicle

exceeds a speed of 40 mph (65 km/h) and will

remain active as long as the speed is over

approx. 37 mph (60 km/h).

If the vehicle is being driven errati-

cally, the driver will be alerted by an

audible signal and the message

Driver Alert Time for a break

displayed. The warning will be repeated after

a short time if the driving pattern remains the

same.
Press the OK button to erase a message.

WARNING

•

An alert should be taken seriously

since it is sometimes difficult for a

driver to realize that he/she is fatigued.

•

In the event of a warning or if the

driver feels fatigued, stop as soon as

possible in a safe place and rest.

Lane Departure Warning (LDW) –

introduction

The LDW function is designed to help reduce

the risk of accidents in situations where the

vehicle unintentionally leaves its lane and

there is a risk of driving off the road or into the

opposite lane.

Lane Departure Warning (LDW)

The illustration is generic

LDW uses the camera located at the center,

upper edge of the windshield to monitor the

road's/lane’s side marker lines. If the vehicle

crosses a side marker line or the road’s cen-

ter dividing line, the driver will be alerted by

an audible signal.

WARNING

This feature is only intended to assist the

driver and does not function in all driving,

weather, traffic or road conditions.
As the driver, you have full responsibility

for operating the vehicle in a safe manner.

Park assist – introduction

The park assist system is designed to assist

you when driving into parking spaces,

garages, etc. An audible signal and symbols

in the audio system’s display indicate the dis-

tance to the object.

The park assist system utilizes ultrasound

sensors in the front bumper and rear

bumper(s) to measure the distance to a vehi-

cle or an object that may be close to the front

or rear of your vehicle.

A trailer hitch whose wiring is integrated

with the vehicle's electrical system will be

included in the measurement of the availa-

ble space behind the vehicle.

WARNING

Park Assist is an information system, NOT

a safety system. This system is designed

to be a supplementary aid when parking

the vehicle. It is not, however, intended to

replace the driver's attention and judge-

ment.

Signals from the park assist system

View in the display (warning for objects front left/

right rear)

Visual indicator

The audio system’s display gives an overview

of the vehicle’s position in relation to a

detected object.
The marked sectors in the display indicate

that one or more of the sensors has detected

an object. The closer the car symbol comes

to a sector, the closer the vehicle is to the

object.
If the infotainment system is switched off, the

park assist system will not be able to provide

a visual indicator. An audible signal will still

be provided.

07 Driver support

233

Audible signal

The Park Assist system uses an intermittent

tone that pulses faster as you come close to

an object, and becomes constant when you

are within approximately 1 ft (30 cm) of an

object in front of or behind the vehicle. If

there are objects within this distance both

behind and in front of the vehicle, the tone

alternates between front and rear speakers.

CAR menu system. See My Car – introduc-

The level of the audible signal can be low-

ered/raised with the infotainment volume

control. The level can also be set in the MY

tion (p. 76) for a description of the menu

system.

If the volume of another source from the

audio system is high, this will be automati-

cally lowered.

Rear park assist

G017833

The distance monitored behind the vehicle is

approximately 5 ft (1.5 m). The audible signal

comes from the rear speakers.
The system must be deactivated when towing

a trailer, carrying bicycles in a rear-mounted

carrier, etc, which could trigger the rear park

assist system's sensors.

manually, see Park assist – operation

•

Rear park assist is deactivated auto-

matically when towing a trailer if Volvo

genuine trailer wiring is used. If a non-

Volvo trailer hitch is being used, it may

be necessary to switch off the system

(p. 234).

•

The system will not detect high

objects, such as a loading dock, etc.

•

Objects such as chains, thin shiny

poles or low objects may temporarily

not be detected by the system. This

may result in the pulsing tone unex-

pectedly stopping instead of changing

to a constant tone as the vehicle

approaches the object. In such cases,

use caution when backing up or stop

the vehicle to help avoid damage.

07 Driver support

234

Front park assist

G021424

The distance monitored in front of the vehicle

is approximately 2.5 ft (0.8 m). The audible

signal comes from the audio system's front

speakers.
It may not be possible to combine auxiliary

headlights and front park assist since these

lights could trigger the system's sensors.

Front park assist is deactivated when the

parking brake is applied and or when the

gear selector is in the P position.

Cleaning the sensors
The sensors must be cleaned regularly to

ensure that they work properly. Clean them

with water and a suitable car washing deter-

gent.

Location of the front sensors

Location of the rear sensors

cause incorrect warning signals.

If the sensors are obstructed by e.g., dirt,

snow, or ice, this could result in false

warning signals from the park assist sys-

tem.

is shown

on the information display, this indicates that

the system is not functioning properly and

has been disengaged. Consult a trained and

qualified Volvo service technician.

CAUTION

In certain circumstances, the park assist

system may give unexpected warning sig-

nals that can be caused by external sound

sources that use the same ultrasound fre-

quencies as the system. This may include

such things as the horns of other vehicles,

wet tires on asphalt, pneumatic brakes,

motorcycle exhaust pipes, etc. This does

not indicate a fault in the system.

Rear Park Assist Camera (PAC) –

introduction

The Park Assist Camera is designed to pro-

vide the driver with a view of the area behind

the vehicle when backing up.

Introduction
PAC uses the display in the center console to

show the area behind the car while you are

backing up.
PAC also shows guiding lines in the on-

screen image to indicate the direction that the

vehicle will take as it moves rearward, which

helps simplify parallel parking, backing into a

tight space or when attaching a trailer to the

vehicle.
The images of vehicles in this section are

generic and may not depict your specific

model.

Rear Park Assist Camera (PAC) – opera-

A trailer hitch whose wiring is integrated

with the vehicle's electrical system will be

included in the measurement of the availa-

ble space behind the vehicle.

WARNING

•

PAC is designed to be a supplemen-

tary aid when parking the vehicle. It is

not, however, intended to replace the

driver’s attention and judgment.

•

The camera has blind spots where it

cannot detect objects or people

behind the vehicle.

•

Pay particular attention to people or

animals that are close to the vehicle.

•

Objects seen on the screen may be

closer than they appear to be.

Rear Park Assist Camera (PAC) –

function

Function

The driver sees what is behind the vehicle

and if a person or animal should suddenly

appear from the side.
PAC is mounted on the tailgate, near the

opening handle.
The camera has built-in electronics that help

reduce the “fish-eye” effect so that the image

shown on the screen is as natural as possi-

ble. This may cause some objects on the

screen to “lean,” which is normal.

Ambient lighting conditions

The camera automatically monitors the ambi-

ent lighting conditions behind the vehicle and

constantly adjusts sensitivity to light. This

may cause the brightness and quality of the

image on the screen to vary slightly. Sensitiv-

ity to light is increased in dark conditions or in

bad weather, which may affect image quality.
If the image on the screen seems too dark,

brightness can be increased with the thumb

wheel on the lighting panel.
