WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
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 faster than the set speed for more than
1 minute.
In this happens, the driver will have to regu- late the vehicle's speed.
NOTE
If the accelerator pedal is only depressed for a short time, such as when passinganother vehicle, ACC is deactivated tem-porarily and is reactivated when the pedalis released.
Automatic standby modeACC is linked to other systems such as the stability system. If this system is not function-ing properly, ACC will switch off automati-cally. In the event of automatic deactivation, an audible signal will sound and the message
Cruise control Cancelled is shown in the
instrument panel. The driver must then inter- vene and adapt the vehicle's speed to thesurrounding traffic and regulate the distanceto the vehicle ahead. An automatic switch to standby mode may be caused if:
• engine speed (rpm) is too high/low
• The driver's door is opened
• The driver unbuckles his/her seat belt
• the vehicle's speed goes below 18 mph (30 km/h)
• the wheels lose traction
• brake temperature is high
• the radar sensor is obstructed by, forexample, wet snow or rain.
Resuming the set speedIf ACC is in standby mode, it can be reactiva- ted by pressing the
button on the steering
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.
Turning ACC off completely
Controls and display
Resume previous settings.
Off/On/Standby mode
• From standby mode, press (2)
once.
• From active mode, press (2)
twice.
The set speed and time interval are then cleared from the system's memory and can- not be resumed by pressing (1)

WARNING
• In certain situations, the system can- not provide warnings or warnings maybe delayed if traffic conditions or otherexternal factors make it impossible forthe radar sensor or camera to detect apedestrian, a cyclist or a vehicleahead.
• Warnings may not be provided if thedistance to the vehicle ahead is short,or if movements of the steering wheel/brake pedal are great, such as duringactive driving.
• The sensor system has a limited rangefor pedestrians/cyclists and provideswarnings and braking effect mosteffectively at speeds up to 30 mph(50 km/h). For stationary or slow-mov-ing vehicles, the system functions bestif your vehicle’s speed is belowapproximately 45 mph (70 km/h).
• Warnings for stationary or slow-mov-ing vehicles may not be provided indark conditions or in poor visibility.
The Pedestrian and Cyclist Detection with Full Auto Brake system uses the same radar sen-sors as Adaptive Cruise Control. For moreinformation on the radar sensor and its limita-tions, see Adaptive Cruise Control – limita-tions (p. 181).
NOTE
If warnings are given too frequently, the warning distance can be reduced (see Col-lision warning* – operation (p. 200)). Thiscauses the system to provide later warn-ings, which decreases the total number ofwarnings 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 youapproach a vehicle ahead at very lowspeed, such as when parking.
• The driver's actions always have high-est priority and override the Pedestrianand Cyclist Detection with Full AutoBrake system. This means that thesystem will not intervene in situationswhere the driver is actively steering,braking or pressing the acceleratorpedal, even if a collision is imminent.
• When Auto-brake has prevented a col-lision with a stationary object, yourvehicle will remain at a standstill forapprox. 1.5 seconds. If your vehiclehas been braked for a moving vehicleahead, your vehicle's speed will bereduced to the same speed as thatvehicle's.

Driver Alert System
The Driver Alert System is designed to help a driver who may be becoming fatigued or whois inadvertently leaving the lane.
IntroductionThe Driver Alert System consists of two differ-ent functions that can be switched ontogether or separately.• Driver Alert Control (DAC)
, see Driver
Alert Control (DAC) – introduction (p. 210)
• Lane Departure Warning (LDW) 7
, see
Lane Departure Warning (LDW) – intro-duction (p. 215)
or
• Lane Keeping Aid (LKA) 8
, see Lane
Keeping Aid (LKA) – introduction (p. 220)
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 of40 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 bypainted lines on each side.
WARNING
The Driver Alert System does not function in all situations and is designed to be asupplementary aid. It is not, however,intended to replace the driver’s attentionand judgement.
Driver Alert Control (DAC) – introduction
DAC is intended to alert the driver if his/her driving becomes erratic, such as if the driveris distracted or fatigued. DAC is designed to help detect a slowly changing driving pattern. It is primarilyintended to be used on main roads and is notmeant for use in city traffic.
A camera monitors the painted lines marking the lane in which the vehicle is traveling andcompares the direction of the road with thedriver’s movements of the steering wheel.The driver is alerted if the vehicle does notfollow the lane smoothly.

Lane Keeping Aid (LKA) – introduction
The LKA function is designed to help reduce the risk of accidents in situations where thevehicle unintentionally leaves its lane andthere is a risk of driving off the road or into theopposite lane.
LDW or LKAYour vehicle may be equipped with LaneDeparture Warning (LDW) or Lane KeepingAid (LKA), depending on your choice of engine. If you are uncertain as to which of
these optional systems is in your vehicle:
• Press the
MY CAR button on the center
console to open the menu system. Scroll to
SettingsDriver support system.
The system in your vehicle (Lane
Departure Warning or Lane Keeping
Aid) will be displayed there.
If your vehicle is equipped with Lane Departure Warning (LDW), see Lane Depar-ture Warning (LDW) – introduction (p. 215) fordetailed information.
LKA functionThe LKA function is primarily intended for useon highways or other major roads with clearlymarked side marker and center lines.
The illustration is generic
LKA uses the camera located at the center, upper edge of the windshield to monitor theroad's/lane’s side marker lines. If the vehicle crosses a side marker line or the road’s center dividing line, LKA will provideactive steering assistance to help steer itback into the lane. The driver will also be alerted by vibrations in the steering wheel.
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.

Lane Keeping Aid (LKA) – operation
LKA is active at speeds above 40 mph (65 km/h) on highways or other major roadswith clearly marked side/lane marker andcenter lines. On narrow roads where the dis-tance between side/lane marker lines is lessthan approximately 8.5 feet ( 2.6 meters), LKAwill be temporarily deactivated.
LKA monitors and follows the marker lines (the red lines in the illustration)• White
side marker lines: the function is
active and "sees" one or both of the road's side marker lines.
• Gray
side marker lines: the function is
active but cannot "see" one or both of theroad's side marker lines.
LKA intervening on the right side (the red line)
When LKA is working actively, this is indi- cated by:
• Red
side marker line: the line being
crossed.
On/Off
LKA can be switched on or off by pressing the button on the center console. A light in the button illuminates when the function ison. Depending on the number of optional fea- tures installed in the vehicle, there may not bespace for the On/Off button on the centerconsole. If this is the case, LKA can beswitched on or off in the
MY CAR menu sys-
tem. The following LKA-related settings can also be made in MY CAR, under

Steering assistLKA attempts to keep the vehicle within the lane's side marker lines.
LKA provides steering assistance
If the vehicle approaches one of the lane's side marker lines and the turn signals are
not being used , LKA will attempt to steer the
vehicle back into the lane.
Vibration warnings
LKA provides vibrations in the steering wheel and steering assistance 11
.
If the vehicle crosses a marker line, LKA pro- vides a warning in the form of vibrations inthe steering wheel. This occurs even if thesteering assist function has been deactivated.
Dynamic cornering
LKA does not intervene in sharp left curves
In certain cases, LKA allows the vehicle to cross marker lines without providing a vibra-tion warning or steering assistance, for exam-ple, during dynamic cornering as shown inthe illustration where the driver's view of theroad and traffic conditions make this possi-ble.

Lane Keeping Aid (LKA) – limitations
The camera used by LKA has the same limi- tations as the human eye. See The camera’slimitations (p. 205) for more information aboutthe camera's limitations.
NOTE
In certain cases, it may be difficult for LKA to assist the driver correctly. In the follow-ing conditions, it may be preferable to turnLKA off:• Road construction areas
• Winter road conditions
• Poor road surfaces
• A very sporty driving style
• Bad weather conditions with poor visi- bility
WARNING
Hands on the steering wheel
: In order for
LKA to function correctly, the driver's hands have to be on the steering wheel,which LKA monitors steadily. If this is notthe case, the driver will be alerted by a textmessage to actively steer the vehicle. If this is not done, LKA will go into standby mode and will remain disengaged until thedriver begins to actively steer the vehicleagain.
