DRIVER SUPPORT
* Option/accessory.
266
Driver support systems
The vehicle is equipped with a number of driver support systems that can provide the driver withactive or passive assistance in various situations.
The system can, for example, help the driver maintain a set speed or a set time interval to thevehicle ahead, help prevent a collision by warningthe driver and applying the brakes, or assist thedriver while parking. Some of the systems are standard and others are options. This also varies from market to market.

Speed-dependent steering wheelresistance
Speed-dependent power steering increases the steering wheel resistance in pace with the vehi-cle's speed to give the driver an enhanced feel-ing of control and stability.
Steering may feel stiffer on highways. When parking and at low speeds, it will be easier tomove the steering wheel.
NOTE
In some situations, the power steering may become too hot and require temporary cool-ing – during such time the power steering willwork at reduced output and the steeringwheel may feel more difficult to move. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage as well as a STEERING WHEELsymbol.

Standby mode due to action by the driver
Adaptive Cruise Control will be temporarily deac- tivated and put in standby mode if:
• the brakes are applied.
• the gear selector is moved to
N
• the vehicle is driven faster than the setspeed for more than 1 minute
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic standby mode
Adaptive Cruise Control is dependent on other systems, such as Electronic Stability Control (ESC 49
). If any of these other systems stops
working, Adaptive Cruise Control will automati- cally switch off.
WARNING
With automatic standby mode, the driver is warned by an acoustic signal and a messageon the instrument panel. • The driver must then regulate vehicle speed, apply the brakes if necessary, andmaintain a safe distance to other vehicles. Adaptive Cruise Control may go into standbymode if:
• your vehicle's speed goes below 5 km/h(3 mph) and ACC cannot determine if thevehicle ahead is stationary or if it is anotherobject, e.g. a speed bump.
• your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatACC no longer has a vehicle to follow.
• the driver opens the door.
• the driver unbuckles the seat belt.
• the engine speed (rpm) is too low/high.
• one or more of the wheels lose traction.
• the brake temperature is high.
• the parking brake is applied.
• the camera/radar sensor is covered by snowor heavy rain (the camera lens/radar wavesare blocked)
Reactivating Adaptive Cruise Control from standby mode
Note: This illustration is general and details may vary depending on model.
To reactivate ACC from standby mode:
–Press the button on the steering wheel
(1).
> Speed will be set to the most recently stored speed.
WARNING
A noticeable increase in speed may follow when the speed is resumed with the
steering wheel button.

NOTE
ACC can keep the vehicle stationary for no more than 5 minutes – after that time theparking brake is applied and Adaptive CruiseControl is deactivated. The parking brake must be released before Adaptive Cruise Control can be reactivated.
Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivated when the vehicle is at a standstill and AdaptiveCruise Control will go into standby mode. Thismeans that the brakes will be released and thevehicle could begin to roll. The driver mustactively apply the brakes to keep the vehicle sta-tionary. This can occur if:
• the driver depresses the brake pedal
• the parking brake is applied
• the gear selector is moved to the
P
, N
or R
positions
• the driver puts Adaptive Cruise Control in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will beapplied to keep the vehicle at a standstill. This occurs if Adaptive Cruise Control is keepingthe vehicle stationary using the brakes and:
• the driver opens the door or unbuckleshis/her seat belt
• ACC has kept the vehicle at a standstill formore than approx. 5 minutes
• the brakes overheat
• the driver switches off the engine manually.

Switching target vehicles with PilotAssist
At certain speeds, models with automatic trans-
missions and Pilot Assist can switch target vehi-cles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When Pilot Assist is actively following another vehicle at speeds under 30 km/h (20 mph) and
switches targets from a moving vehicle to a sta-
tionary vehicle, Pilot Assist will brake for the sta-tionary vehicle.
WARNING
When Pilot Assist follows another vehicle at speeds over approx. 30 km/h (20 mph) and
changes target vehicle – from a moving vehi- cle to a stationary one – Pilot Assist will ignore the stationary vehicle and instead
accelerate to the stored speed.
• The driver must then intervene and apply the brakes.
Automatic standby mode when switching
targets
Pilot Assist disengages and goes into standby mode if:
• your vehicle's speed goes below 5 km/h(3 mph) and Pilot Assist cannot determine ifthe target object is a stationary vehicle oranother object, e.g. a speed bump.
• your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatPilot Assist no longer has a vehicle to follow.

Automatic braking with Pilot Assist
Pilot Assist has a special braking function in slow traffic and at a standstill.
Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stop- ped at a traffic light, driving will resume automati-cally if the vehicle is stopped for less thanapprox. 3 seconds. If it takes more than 3 sec-onds for the vehicle ahead to begin moving again,Pilot Assist will go into standby mode and theAuto-hold brake function will activate.
–Pilot Assist can be reactivated by:
• Pressing the
button on the steering
wheel keypad.
• Pressing the accelerator pedal.
> Pilot Assist will resume following the vehi- cle ahead if it begins to move within approx. 6 seconds.
NOTE
Pilot Assist can keep the vehicle stationary for no more than 5 minutes – after that timethe parking brake is applied and the functionis deactivated. The parking brake must be released before Pilot Assist can be reactivated.
