Electronic Stability Control symbolsand messages
A number of symbols and messages related toElectronic Stability Control (ESC) may be dis-played in the instrument panel.
Some examples of symbols and messages areshown in the table below.
Symbol MessageMeaning
Steady glow forapprox. 2 seconds.System check when the engine is started.
Flashing light.The ESC is actively operating.
Steady glow.Sport mode is activated.
Note: The ESC system is not deactivated in this mode, but has partially reduced functionality.
ESC
Temporarily off
The ESC system's functionality has been temporarily reduced due to high brake system temperatures. Thefunction will be automatically reactivated when the brakes have cooled.
See the message in the instrument panel.
ESC
Service required
The ESC system is not functioning properly.
Stop the vehicle in a safe place, turn off the engine and then restart it.
Consult a workshop if the message persists ‒ an authorized Volvo workshop is recommended.
A text message can be erased by briefly pressing
the button in the center of the right-sidesteering wheel keypad.
If the message persists: Contact a workshop ‒ anauthorized Volvo workshop is recommended.

Temporarily deactivating using the
accelerator pedal
The set maximum speed can be temporarilydeactivated and exceeded using the acceleratorpedal without first putting the Speed Limiter instandby mode, e.g. when quick acceleration isrequired.
To do so:
1. Depress the accelerator as far as possibleand then release it when the desired speedhas been reached.
> The Speed Limiter will remain activatedand the symbol in the instrument panelwill be WHITE.
2. Release the accelerator pedal fully when thetemporary acceleration is completed.
> The vehicle will use engine braking toautomatically slow down to a speed belowthe most recently set maximum speed.

For vehicles with both CC and ACC
–Change a set speed by pressing the (1)
or (3) buttons briefly or by pressing andholding them:
Press briefly: Press briefly: each presschanges the speed in +/- 5 mph(+/- 5 km/h) increments.
Press and hold: release the button whenthe set speed indicator (4) has moved tothe desired speed.
The most recently set speed will be stored.
If speed is increased by depressing the accelera-
tor pedal while pressing the (1) button onthe steering wheel, the vehicle's speed when thebutton is pressed will be stored as the set speed.
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.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applyingthe brakes. On downgrades, it can sometimes bedesirable to roll a bit faster and let speed bereduced instead by engine braking alone. Thedriver can temporarily disengage the Cruise Con-trol braking function.
To disengage CC:
–Press the accelerator pedal about halfwaydown and then release it.
> Cruise Control will automatically disen-gage the automatic brake function andspeed will only be reduced using theengine braking function.
How drive mode affects cruise control
The way the cruise control maintains the vehicle'sspeed can vary depending on the selected drive
mode22.
Cruise Control Eco Cruise with ECO drive
mode
In the ECO drive mode, cruise control's accelera-tion and deceleration will be smoother than inother drive modes to help provide optimal fuelefficiency and reduced environmental impact.Because of this, the vehicle's actual speed maybe slightly above or below the set speed.
Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control'sacceleration and deceleration will be faster andmore immediate than in other drive modes.

Standby mode due to action by the driver
Cruise Control will be temporarily deactivated andput 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
The driver must then control the vehicle's speed.
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
Cruise Control will be temporarily deactivated andput in standby mode if:
the wheels lose traction
the engine speed (rpm) is too low/high
the temperature in the brake systembecomes too high
the vehicle's speed goes below 30 km/h(20 mph).
The driver must then control the vehicle's speed.

Control
To start ACC:
The driver's seat belt must be buckled andthe driver's door must be closed.
There must be a vehicle ahead (target vehi-cle) within a reasonable distance or yourvehicle's current speed must be at least15 km/h (9 mph).
Note: This illustration is general and details may varydepending on model.

To temporarily deactivate Adaptive Cruise Controland put it in standby mode:
–Press the button on the steering wheel(2).
>The symbol in the instrument panelchanges color from WHITE to GRAY andthe set speed in the center of the speed-ometer will change from BEIGE to GRAY.
WARNING
If Adaptive Cruise Control is in standbymode, the driver must intervene and regu-late both speed and distance to the vehicleahead.
If the vehicle comes too close to a vehicleahead when Adaptive Cruise Control is instandby mode, the driver is instead warnedof the short distance by the Distance Alertfunction.
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 othersystems, such as Electronic Stability Control
(ESC42). If any of these other systems stopsworking, Adaptive Cruise Control will automati-cally switch off.
WARNING
With automatic standby mode, the driver iswarned by an acoustic signal and a messageon the instrument panel.
The driver must then regulate vehiclespeed, 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)

Adaptive Cruise Control limitations
Adaptive Cruise Control (ACC48) may have lim-ited functionality in certain situations.
Steep roads and/or heavy loads
Adaptive Cruise Control is primarily intended tobe driven on flat roads. The function may not beable to maintain the correct time interval to thevehicle ahead when driving down steep hills. Thedriver should be extra attentive and prepared toapply the brakes.
Do not use Adaptive Cruise Control if thevehicle is carrying a heavy load or towing atrailer.
Other limitations
The Off Road drive mode cannot beselected if Adaptive Cruise Control is acti-vated.
NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".

AA
Cruise control Adaptive Cruise Control
AWHITE symbol: The function is active. GRAY symbol: Standbymode
Switching from ACC to CC
To do so:
1.Press the button on the steering wheelkeypad to put Adaptive Cruise Control instandby mode.
2.Tap the Cruise Control button in the centerdisplay's Function view. The button's indica-tor will change from GRAY to GREEN.

3.Pressing the button on the steeringwheel keypad.
> Cruise Control will start and the vehicle'scurrent speed will be set.
WARNING
Switching from ACC to CC means that thevehicle:
will no longer maintain a preset timeinterval to the vehicle ahead.
will only follow the stored speed and thedriver must therefore apply the brakeswhen necessary.
If CC is active when the engine is turned off, ACCwill be automatically activated the next time theengine is started.
Switching from CC to ACC
To do so:
1.Press the button on the steering wheelkeypad to put Cruise Control in standbymode.
