Toggling between ACC and CC (standard Cruise Control)
Adaptive Cruise Control (ACC) helps the driver maintain a safe distance/time interval tothe vehicle ahead.
Switching from ACC to CCThis may be useful if, for example, the radarsensor is obstructed in some way. SeeAdaptive Cruise Control – limitations (p. 193)for additional information.
• Press and hold the
button; the symbol
in the instrument panel will switch from
to .
> This activates the standard cruise control function (see Cruise control (CC) – intro- duction (p. 181)).
WARNING
Switching from ACC to CC means that:
• Your vehicle will
no longer automati-
cally maintain a set distance to a vehi- cle ahead.
• Only the set speed will be maintainedand the driver will have to apply thebrakes when needed.
Switching from CC to ACC
Switch off cruise control by pressing once
or twice as needed according to the instruc- tions in the previous section "Turning ACC off completely." The next time the system isswitched on, ACC will be reactivated.

Cruise control is designed to assist the driver by maintaining a set speed. It is primarilyintended for use on long straight roads insteady traffic, such as on highways and othermain roads.
Automatic deactivationThe cruise control is automatically deacti-vated
temporarily if one of the following
occurs: • If the speed drops below approximately 20 mph (30 km/h).
• When the brake pedal is depressed.
• If the gear selector is moved to positionN
.
• During wheel spin or wheel lock-up.
• If the vehicle's speed is increased byusing the accelerator pedal for more than1 minute.
• Engine speed (rpm) is too high or too low.
The currently set speed will be saved in the system's memory.
Temporary deactivationThe driver can temporarily deactivate thecruise control by pressing 0. The saved
speed is shown in brackets in the informationdisplay.

Adaptive Cruise Control consists of: • A cruise control system to maintain a set speed
• A system to maintain a set distance to thevehicle ahead, which is expressed as atime interval. For example, you canchoose to remain approximately 2 sec-onds behind the vehicle ahead. Theactual distance required to maintain a2-second interval will vary according thespeed of the vehicles.

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. 193).
NOTE
If warnings are given too frequently, the warning distance can be reduced (see Col-lision warning* – operation (p. 212)). 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. 222)
• Lane Departure Warning (LDW)
, see
Lane Departure Warning (LDW) – intro-duction (p. 227)
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.
NOTE
The camera has certain limitations, see Adaptive Cruise Control – limitations(p. 193).
WARNING
• DAC is not intended to extend the duration of driving. Always plan breaksat regular intervals to help remain alert.
• A warning from DAC should not beignored. A driver may not be aware ofhow fatigued he/she has become.
• In certain cases, fatigue may not affectthe driver’s behavior. In situations ofthis type, no warning will be provided.Therefore, it is important to takebreaks at regular intervals, regardlessof whether or not DAC has given awarning.
