Adaptive Cruise Control (ACC)*
Introduction Adaptive Cruise Control (ACC) is an optional system designed to assist the driver by main- taining a set speed or a set time interval to the vehicle ahead. It is primarily intended for use on long straight roads in steady traffic, such as on highways and other main roads. When the driver has set the desired speed and the time interval to the vehicle ahead, ACC functions as follows: • If there are no other vehicles in the lane
ahead of you, your vehicle will travel at the set speed.
• If ACC's radar sensor detects a slower
moving vehicle in the lane ahead, the sys- tem will adapt your vehicle's speed to help maintain the set time interval to the vehicle ahead. When there are no longer slower moving vehicles ahead, your vehicle will accelerate to resume the set speed.
If ACC is switched off completely or in standby mode and your vehicle comes too close to another vehicle ahead, the driver will be warned by the Distance Alert system (see page 149).
04
WARNING
• Adaptive Cruise Control cannot cover all driving situations and traffic, weather and road conditions. The "Function" section provides information about lim- itations that the driver must be aware of before using this feature.
• This system is designed to be a supple- mentary driving aid. It is not, however, intended to replace the driver's atten- tion and judgement. The driver is responsible for maintaining a safe dis- tance and speed and must intervene if Adaptive Cruise Control does not main- tain a suitable speed or suitable dis- tance to the vehicle ahead.
• Maintenance of ACC components may
only be performed by a trained and qualified Volvo technician.

Adaptive Cruise Control consists of: • A cruise control system to maintain a set
speed
• A system to maintain a set distance to the
vehicle ahead, which is expressed as a time interval. For example, you can choose to remain approximately 2 seconds behind the vehicle ahead. The actual distance required to maintain a 2-second interval will vary according the speed of the vehi- cles.

Adaptive Cruise Control (ACC)*
WARNING
WARNING
WARNING
• Adaptive Cruise Control is not a colli- sion avoidance system. The driver is always responsible for applying the brakes if the system does not detect another vehicle.
• Adaptive Cruise Control does not react to people or animals, or small vehicles such as bicycles and motorcycles. It also does not react to slow moving, parked or approaching vehicles, or sta- tionary objects.
• Do not use Adaptive Cruise Control in demanding driving conditions such as city driving or other heavy traffic situa- tions, in slippery conditions, when there is a great deal of water or slush on the road, during heavy rain or snow, in poor visibility, on winding roads or on high- way on- or off-ramps.
The distance to the vehicle ahead (in the same lane) is monitored by a radar sensor. Your vehi- cle's speed is regulated by accelerating and braking. The brakes may emit a sound when they are being modulated by the adaptive cruise control system. This is normal.
The brake pedal moves when the adaptive cruise control system modulates the brakes. Do not rest your foot under the brake pedal.
The ACC system is designed to smoothly reg- ulate speed. However, the driver must apply the brakes in situations that require immediate braking. This applies when there are great dif- ferences in speed between vehicles, or if the vehicle ahead brakes suddenly.
WARNING
Due to limitations in the radar sensor, brak- ing may occur unexpectedly or not at all, see page 144.
Adaptive Cruise Control can be put in active mode at any permitted speed. However, if the vehicle's speed falls below 18 mph (30 km/h) or if engine speed (rpm) becomes too low, ACC disengages (goes into standby mode) and will no longer modulate the brakes2. The driver will then have to maintain a safe distance to the vehicle ahead.
When Adaptive Cruise Control is in standby mode or is switched off completely, the brakes will not be modulated automatically. The driver must assume full control over the vehicle.
Warning light—driver braking required Adaptive Cruise Control can exert brake force that is equivalent to approximately 40% of the vehicle's total braking capacity. In situations requiring more brake force than ACC can pro- vide and if the driver does not apply the brakes, an audible signal from the Collision Warning system will sound and warning light will illumi- nate (see page 159) in the windshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if the driver is not looking straight ahead may make the visual warning signal in the wind- shield difficult to see.

WARNING
Operation
Adaptive Cruise Control only warns of vehi- cles detected by the radar sensor, see page 144. In some cases there may be no warning or the warning may be delayed. The driver should always apply the brakes when necessary.
04
Steep inclines and/or heavy loads ACC is primarily intended for use on fairly level roads. The system may have difficulty main- taining the correct distance to a vehicle ahead on steep inclines, if the vehicle is carrying a heavy load or is towing a trailer. In these situa- tions, the driver should always be prepared to apply the brakes if necessary.

Different time intervals can be selected and are shown in the display as 1–5 horizontal bars. The greater the number of bars, the longer the time inter- val. One bar represents a time interval of approximately
1 second; 5 bars is approximately 3 seconds. At low speeds, when the distance to the vehicle ahead is short, ACC increases the time interval slightly. In order to follow the vehicle ahead as smoothly as possible, ACC allows the time interval to vary considerably in certain situa- tions.
WARNING
• Only use a time interval that is suitable
in current traffic conditions.
• A short time interval gives the driver lim- ited reaction time if an unexpected sit- uation occurs in traffic.

Adaptive Cruise Control (ACC)*
Standby mode due to action by the driver ACC is temporarily deactivated and put in standby mode: • if the brakes are applied • if the gear selector is moved to N • if the driver drives at a speed higher than
the set speed for more than 1 minute.
In this happens, the driver will have to regulate the vehicle's speed.
04
NOTE
If the accelerator pedal is only depressed for a short time, such as when passing another vehicle, ACC is deactivated temporarily and is reactivated when the pedal is released.
Automatic standby mode Adaptive cruise control is linked to other sys- tems such as the stability and traction control system (DSTC). If this system is not functioning properly, adaptive cruise control is automati- cally deactivated and will go into standby mode. In the event of automatic deactivation, an audi- ble signal will sound and the message Cruise control Cancelled is shown in the display. The driver must then intervene and adapt the
vehicle's speed to the surrounding traffic and regulate the distance to the vehicle ahead. An automatic switch to standby mode may be caused if: • engine speed (rpm) is too high/low • the vehicle's speed goes below 18 mph
(30 km/h)3
• the wheels lose traction • brake temperature is high • the radar sensor is obstructed by, for
example, wet snow or rain.
Resuming the set speed If ACC is in standby mode, it can be reactivated by pressing the wheel keypad. The vehicle will return to the most recently set speed.

WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Passing another vehicle If your vehicle’s speed is being regulated by ACC and the driver indicates that he/she would like to pass the vehicle ahead by using the
left turn signal, ACC can assist by accelerating briefly. This function is active at speeds above approx- imately 45 mph (70 km/h).
WARNING
Please be aware that this function will also cause the vehicle to accelerate briefly in certain situations other than passing another vehicle, for example using the left turn signal to indicate a lane change or a turn toward a highway exit at speeds above approximately 45 mph (70 km/h).
Queue Assist Queue Assist is an added ACC feature that is linked to your vehicle's automatic transmis- sion. Queue Assist consists of the following func- tions: • Enhanced speed interval (including when the vehicle is at a complete stop or is mov- ing at speed below 18 mph (30 km/h)) • Automatic standby mode when ACC
changes target vehicles
• No automatic braking when at a standstill • The parking brake is applied automatically

142
* Option/accessory, for more information, see Introduction.
Please note that the lowest speed that can be set is 18 mph (30 km/h), although ACC can maintain a set speed/distance to a vehicle ahead down to a standstill. Queue Assist con- sists of the following features: Enhanced speed interval
NOTE
The driver's door must be closed and the driver's seat belt must be fastened before ACC can be put in active mode. If the driv- er's seat belt is taken off or if the driver's door is opened, ACC will return to standby mode.
Your vehicle can maintain the set time interval to the vehicle ahead at any permissible speed, including a complete stop. In order to activate ACC at speeds below 18 mph (30 km/h): • The vehicle ahead must be within a rea- sonable distance (not farther away than approx. 100 ft/30 meters)
• The lowest speed that can be selected is 18 mph (30 km/h), although ACC will also help maintain the set time interval to the vehicle ahead at lower speeds, including a complete stop.
During short stops (less than approximately 3 seconds) in slow-moving traffic, your vehicle will begin moving again automatically as soon as the vehicle ahead begins to move. If it takes more than 3 seconds for the vehicle ahead to begin moving, ACC will be automati- cally go into standby mode. The driver will then have to reactivate ACC in one of the following ways: • By pressing • By accelerating up to at least 3 mph
(4 km/h). ACC will then resume following the vehicle ahead.
Your vehicle will then resume following the vehicle ahead at the set time interval.
NOTE
ACC can remain active and keep your vehi- cle at a standstill for up to 4 minutes. After 4 minutes have elapsed, the parking brake will be engaged and ACC will go into standby mode. To reactivate ACC, the driver must release the parking brake (see page 125).

If the vehicle ahead turns suddenly, there may be a stationary vehicle ahead The following only applies at speeds below approximately 18 mph (30 km/h): If ACC changes target vehicles (the vehicle that the radar sensor has detected) from a moving vehicle to a stationary one, the system will apply the brakes in your vehicle.
WARNING
At speeds above 18 mph (30 km/h), ACC will not react to a stationary vehicle and apply the brakes but will instead accelerate to the previously set speed. The driver must actively apply the brakes to stop the vehicle.

• Your vehicle's speed goes below 10 mph (15 km/h) and ACC cannot determine if the target object is a stationary vehicle or some other type of object such as e.g., a speed bump.
• Your vehicle's speed goes below 10 mph (15 km/h) and the vehicle ahead turns so that ACC no longer has a target vehicle to follow.
No automatic braking when at a standstill In certain situations, ACC will no longer apply the brakes and go into standby mode while the vehicle is not moving. This means that the driver will have to apply the brakes. This happens if: • The driver presses the brake pedal • The parking brake is activated • The gear selected is moved to P,N or R • The driver presses the button to put ACC in standby mode
The parking brake is applied automatically In certain situations, ACC will apply the parking brake in order to continue keeping the vehicle at a standstill. This happens if:
• The driver opens the door or takes off
his/her seat belt
• DSTC is put in Sport mode (see page 132) • ACC has kept the vehicle at a standstill for
more than 2 minutes
• The engine has been switched off • The brakes have overheated Turning ACC off completely • From standby mode, press • From active mode, press twice. The set speed and time interval are then cleared from the system's memory and cannot be resumed by pressing
once.
The radar sensor and its limitations In addition to being used by ACC, the radar sensor is also used by Distance Alert (see page 149) and Collision Warning with Full Auto-brake and Pedestrian Detection (see page 158). This sensor is designed to detect cars or larger vehicles driving in the same direction as your vehicle, in the same lane.
WARNING
Accessories or other objects, such as extra headlights, must not be installed in front of the grille. Modification of the radar sensor could make its use illegal.
The radar sensor's capacity to detect vehicles ahead is impeded: • if the radar sensor is obstructed and can- not detect other vehicles, for example in heavy rain, or if snow or other objects are obscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor clean.
• if the speed of vehicles ahead is signifi-
cantly different from your own speed.

City Safety™
Introduction City Safety™1 is a support system designed to help the driver avoid low speed collisions when driving in slow-moving, stop-and-go traffic. City Safety™ is not active if your vehicle’s speed is below approximately 2 mph (4 km/h). This means that City Safety™ will not react if your vehicle approaches another vehicle at very low speed, for example, when parking. The function is active at speeds up to approx- imately 30 mph (50 km/h) and assists the driver by applying the brakes automatically, thereby avoiding or helping to reduce the effects of a collision. City Safety™ is designed to intervene as late as possible to help avoid unnecessary activa- tion. City Safety™ triggers brief, forceful braking if a low-speed collision is imminent. However, the system will not intervene in situations where the driver actively steers the vehicle or applies the brakes, even if a collision cannot be avoi- ded. This is done in order to always give the driver’s actions highest priority. City Safety™ activates in situations where the driver has not applied the brakes in time, which
means that the system cannot help the driver in all situations. City Safety™ should not be used to alter the way in which the driver operates the vehicle. The driver should never rely solely on this sys- tem to safely stop the vehicle. Normally, the occupants of the vehicle will not be aware of City Safety™ except when the system intervenes when a low-speed collision is imminent. If the vehicle is also equipped with the optional Collision Warning with Full Auto-brake and Pedestrian Detection system, the two systems interact. For more information about the Colli- sion Warning with Auto-brake system, see page 158.
WARNING
• City Safety™ is a supplemental aid to
the driver. It can never replace the driver’s attention to traffic conditions or his/her responsibility for operating the vehicle in a safe manner.
• City Safety™ does not function in all
driving situations or in all traffic, weather or road conditions.
WARNING
• City Safety™ only reacts to vehicles
traveling in the same direction as your vehicle and does not react to small vehi- cles, bicycles or motorcycles or to peo- ple or animals.
• City Safety™ is not activated when your
vehicle is backing up.
• City Safety™ functions at speeds up to 30 mph (50 km/h). This system can help prevent a collision if the difference in speed between your vehicle and the vehicle ahead is less than 9 mph (15 km/h). If the difference in speed is greater, a collision cannot be avoided but the speed at which the collision occurs can be reduced. The driver must apply the vehicle’s brakes for full brak- ing effect.
• City Safety™ will not intervene in a
potential collision situation if the vehicle is being driven actively. The driver is always responsible for maintaining a safe distance to a vehicle or object ahead.

Location of the laser sensor in the windshield2
City Safety™ monitors traffic ahead of you using a laser sensor mounted in the upper sec- tion of the windshield. If a collision is imminent, City Safety™ will automatically apply the brakes, which may feel like hard braking. If the difference in speed between your vehicle and the vehicle ahead is more than approxi- mately 9 mph (15 km/h), City Safety™ alone cannot prevent a collision from taking place. The driver must apply the brakes to help avoid a collision or reduce its effect. When the function activates and applies the brakes, a message will appear in the informa-Using City Safety™
NOTE
The City Safety™ function is activated auto- matically each time the engine has been switched off and restarted.

The laser sensor has certain limitations and its function may be reduced (or it may not function at all) in conditions such as heavy rain or snowfall, or by dense fog or thick, blowing dust or snow. Condensation, dirt, ice or snow on the windshield may also interfere with the sensor’s function.
Objects such as warning flags hanging from long objects on the roof or accessories such as auxiliary lights or protective arches on the front of the vehicle that are higher than the hood may also impede the sensor’s function. Braking distance to the vehicle ahead increa- ses on slippery road surfaces, which may reduce City Safety’s capacity to avoid a colli- sion. In situations like this, the DSTC system (see page 132) will help provide the best pos- sible braking capacity and stability. City Safety™ emits a laser beam and measures the way in which the light is reflected. There- fore, vehicles or objects with low-reflective sur- faces may not be detected. Normally, the license plate and taillight reflectors give the rear section of a vehicle ahead sufficient reflec- tive surfaces to be detected.

NOTE
• Keep the windshield in front of the laser sensor free of ice, snow, dirt, etc. See page 153.
• Snow or ice on the hood deeper than 2 inches (5 cm) may obstruct the sen- sor. Keep the hood free of ice and snow. • Do not mount or in any way attach any-
thing on the windshield that could obstruct the laser sensor.
Cause
Action
The area of the windshield in front of the sensor is dirty or covered by ice or snow.
The laser sensor's field of view is obstructed.
Clean the wind- shield or remove the ice/snow.
Remove the obstruction.
Troubleshooting If Windscreen Sensors blocked appears in the information display, this indicates that the City Safety™ laser sensor is obstructed in some way and cannot detect vehicles ahead of you, which means that the system is not func- tioning. However, this message will not be displayed in all situations in which the sensor is obstructed. For this reason, the driver must ensure that the area of the windshield in front of the sensor is always kept clean. The following table shows some of the situa- tions that can cause the message to be dis- played and suggested actions.
CAUTION
If a crack, scratch or stone chip should occur in the section of the windshield in front the laser sensor, contact a trained and qualified Volvo service technician to repair or replace the windshield (see the illustra- tion showing the location of the sensor on page 153). Failing to do so may result in reduced City Safety™ functionality. To help prevent reduced functionality, please also observe the following: • Before the windshield is replaced, con- tact a Volvo retailer to ensure that the correct windshield is ordered and installed. If the wrong type of windshield is used, this may cause City Safety™ to function improperly or not at all. Volvo recommends the use of only Genuine Volvo Replacement Windshields.
• When replacing windshield wipers, use
the same type or ones approved by Volvo.

Collision warning with Full Auto-brake and Pedestrian Detection*
The system should not be used in such a way that the driver changes his/her way of operat- ing the vehicle. If the driver relies entirely on the system, the chances of an accident eventually occurring increase considerably. The Collision Warning and City Safety™ sys- tems supplement each other. See page 152 for detailed information about City Safety™.
WARNING
No automatic system can be guaranteed to function 100% correctly in all situations. For that reason, never test the Auto-brake sys- tem by driving toward a person or object. This could result in serious injury or death.
WARNING
• Collision Warning does not work in all driving, traffic, weather and road condi- tions. It does not react to vehicles not traveling in the same direction as your vehicle.
• Collision Warning does not react to ani-
mals.
• Warnings are only provided when the risk of collision is high. The "Function" section provides information about lim- itations that the driver must be aware of before using Collision Warning.
• Collision Warning will not provide a
warning or brake the vehicle for pedes- trians at speeds above 50 mph (80 km/h).
04
Introduction Collision Warning with Full Auto-brake and Pedestrian Detection is designed to assist the driver if there is a risk of a collision with a pedestrian, a vehicle ahead that is at a stand- still or one that is moving in the same direction as your vehicle. Collision Warning consists of the following three functions: • Collision Warning warns the driver of a
potential collision situation.
• Brake Support helps the driver brake effi-
ciently in a critical situation.
• Auto-brake brakes the vehicle automati-
cally if a collision with a pedestrian or another vehicle cannot be avoided and the driver does not apply the brakes in time or steer around the person/vehicle. Auto- brake can help prevent a collision or reduce the speed at which a collision occurs.
Since Collision Warning with Full Auto-brake and Pedestrian Detection is activated in cir- cumstances where the driver should have begun braking much sooner, the system will not be able to assist the driver in all situations. This system is designed to activate as late as possible to help avoid unnecessary interven- tion.
158
* Option/accessory, for more information, see Introduction.
WARNING
• Collision Warning will not provide a
warning or brake the vehicle for pedes- trians in darkness or in tunnels, even if there is street lighting in the area.
• The auto-brake function can help pre- vent a collision or reduce the speed at impact but the driver should always apply the brakes for the best possible braking effect, even if auto-brake is actively applying the brakes.
• Never wait for a collision warning. This system is designed to be a supplemen- tary driving aid. It is not, however, intended to replace the driver's atten- tion and judgement. The driver is responsible for maintaining a safe dis- tance and speed, even when the colli- sion warning system is in use.
• Maintenance of the Collision Warning
system's components must only be performed by a trained and qualified Volvo technician.

Function
Function overview
Audio-visual warning signals, collision risk
Radar sensor
Camera
Collision Warning The radar sensor and the camera work together to detect a pedestrian, stationary vehicles and vehicles that are moving in the same direction as your vehicle. If there is a risk of collision with a vehicle or a pedestrian, the driver is alerted by a flashing red warning light and an audible warning signal. Collision warn- ing is active at speeds above 3 mph (4 km/h).
Brake Support If the risk of collision continues to increase after the collision warning has been given, Brake Support is activated. Brake Support prepares the brake system to react quickly, and the brakes are applied slightly. This may be expe- rienced as a light tug. If the brakes are applied quickly, full braking effect will be provided. Brake Support also increases brake force if the system determines that the driver has not applied adequate pres- sure on the brake pedal.
Auto-brake If a collision is imminent and the driver has not applied the brakes or begun to steer around the vehicle or pedestrian, the auto-brake function is activated without the driver pressing the brake pedal. Full brake force is applied to help reduce the vehicle’s speed when the collision occurs or limited brake force is applied if this is sufficient to avoid the collision.
NOTE
The auto-brake and brake support functions are always on and cannot be turned off.

WARNING
• The setting Short should only be used
in situations where traffic is light and moving at low speeds.
• Collision Warning alerts the driver to the risk of a collision but this function can- not reduce the driver’s reaction time.
• For Collision Warning to be as effective as possible, it is recommended that Dis- tance Alert be set to 4 or 5, see page 149.
NOTE
• When Adaptive Cruise Control is used, the warning light and signal will be used by that function, even if the warnings provided by Collision Warning have been deactivated by the driver.
• In situations where traffic is moving at considerably different speeds, or if the vehicle ahead brakes suddenly, warn- ings may be considered to be late, even if the setting Long has been selected.
Checking settings The current Collision Warning settings can be checked by pressing MY CAR on the center console control panel and going to Settings Driver support systems
Car settings Collision Warning.
Limitations Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver is not looking straight ahead may make the visual warning signal in the windshield difficult to see. For this reason, always activate the audible warning signal. Slippery driving conditions increase braking distance, which can reduce the system's

capacity to avoid a collision. In these condi- tions, the ABS and DSTC systems provide the best possible braking effect while helping to maintain stability.
NOTE
The visual warning signal may be temporar- ily disengaged in the event of high passen- ger compartment temperature due to strong sunlight, etc. If this occurs, the audible warning signal will be used, even if it has been deactivated in the menu system.

Collision warning with Full Auto-brake and Pedestrian Detection*
WARNING
NOTE
• In certain situations, the system cannot provide warnings or warnings may be delayed if traffic conditions or other external factors make it impossible for the radar sensor or camera to detect a pedestrian or a vehicle ahead.
• Warnings may not be provided if the distance to the vehicle ahead is short, or if movements of the steering wheel/ brake pedal are great, such as during active driving.
• The sensor system has a limited range for pedestrians and provides warnings and braking effect most effectively at speeds up to 30 mph (50 km/h). For sta- tionary or slow-moving vehicles, the system functions best if your vehicle’s speed is below approximately 45 mph (70 km/h).
• Warnings for stationary or slow-moving
vehicles may not be provided in dark conditions or in poor visibility.
The Collision Warning system uses the same radar sensors as Adaptive Cruise Control. For more information on the radar sensor and its limitations, see page 144.
If warnings are given too frequently, the warning distance can be reduced (see page 160). This causes the system to pro- vide later warnings, which decreases the total number of warnings provided.
WARNING
• The system is not activated at speeds under approx. 2 mph (4 km/h). There- fore, it will not brake your vehicle if you approach a vehicle ahead at very low speed, such as when parking.
• The driver's actions always have high- est priority and override the Collision Warning system. This means that the system will not intervene in situations where the driver is actively steering, braking or pressing the accelerator pedal, even if a collision is imminent.
• When Auto-brake has prevented a col- lision with a stationary object, your vehi- cle will remain at a standstill for approx. 1.5 seconds. If your vehicle has been braked for a moving vehicle ahead, your vehicle's speed will be reduced to the same speed as that vehicle's.

The camera’s limitations The camera is used by Collision Warning with Auto-brake, Driver Alert Control (see page 166), and Lane Departure Warning (see page 169).
NOTE
• To help protect the camera in very hot
conditions, it may be temporarily switched off for approximately 15
minutes after the engine has been started.• Keep the section of the windshield in
front of the camera clean and free of ice, snow, or condensation.
04
WARNING
• The camera has the same limitations as
the human eye. In other words, its “vision is impaired” by adverse weather conditions such as heavy snowfall, dense fog, etc. These conditions may reduce the function of systems that depend on the camera or cause these systems to temporarily stop function- ing.
• Never place any objects, decals, etc., on the windshield in front of the camera. This could reduce or block the camera’s function, and could cause one or more of the systems that utilize the camera to stop functioning.
• Strong sunlight, reflections from the
road surface, ice or snow covering the road, a dirty road surface, or unclear lane marker lines may drastically reduce the camera’s capacity to detect the side of a lane, a pedestrian or another vehi- cle.
162
* Option/accessory, for more information, see Introduction.
Pedestrians
The system cannot identify all pedestrians The Collision Warning system can only identify and detect a pedestrian who is standing upright. This person can be standing still, walk- ing or running. This means that the system has to be able to identify a person's head, arms, shoulders, legs, the upper and lower parts of the body and a person's pattern of movement when walking or running. If parts of the body are not visible to the cam- era, the system cannot detect the pedestrian. The following conditions apply: • In order to detect a pedestrian, the system must have a full view of the person's entire

• The system cannot detect a pedestrian
carrying a large object.
• The camera's capacity to see a pedestrian at dawn or dusk is limited, much as it is for the human eye.
• The camera's function is deactivated and will not detect a pedestrian in darkness or in tunnels, even if there is street lighting in the area.
WARNING
• Collision Warning with Full Auto-brake and Pedestrian Detection is designed to be a supplementary driving aid. It is not, however, intended to replace the driv- er's attention and judgement. The driver is always responsible for operating the vehicle in a safe manner.
• The system cannot detect all pedes-
trians in all situations, such as in dark- ness/at night and cannot detect parti- ally hidden pedestrians, people who are less than approx. 32 in. (80 cm) tall, or people wearing clothing that obscures the contours of their bodies.

Driver Alert System*
Introduction The Driver Alert System is designed to help a driver who may be becoming fatigued or who is inadvertently leaving the lane. The Driver Alert System consists of two differ- ent functions that can be switched on together or separately. • Driver Alert Control (DAC) • Lane Departure Warning (LDW), see
page 169
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 dependent on the road/lane being clearly marked by pain- ted lines on each side.
WARNING
The Driver Alert System does not function in all situations and is designed to be a sup- plementary aid. It is not, however, intended to replace the driver’s attention and judge- ment.
Driver Alert Control (DAC)– introduction
This function is intended to alert the driver if his/her driving becomes erratic, such as if the driver is distracted or fatigued.
NOTE
The camera has certain limitations, see page 144.
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.
DAC is designed to help detect a slowly chang- ing driving pattern. It is primarily intended to be used on main roads and is not meant for use in city traffic.
WARNING
• DAC is not intended to extend the dura-
tion of driving. Always plan breaks at regular intervals to help remain alert.
• 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 warn- ing.
Limitations In certain situations, DAC may provide warn- ings even if the driver’s driving pattern has not become erratic. • if the driver is testing the LDW function • in strong crosswinds • on grooved road surfaces.
166
* Option/accessory, for more information, see Introduction.
04 Driver support
Driver Alert System*
If the vehicle is being driven erratically, the driver will be alerted by an audible signal and the message Driver Alert, Time for a break is displayed. The warning will be repeated after a short time if the driving pattern remains the same.
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.
