Electronic Stability Control
The Electronic Stability Control (ESC1) functionhelps the driver avoid skidding and improves thevehicle's directional stability.
This symbol will be displayed inthe instrument panel when theESC system is intervening.
When the ESC has intervenedto apply the brakes, a pulsingsound may be heard and thevehicle may accelerate more slowly than expec-ted when the accelerator pedal is depressed.
The ESC system consists of the following sub-functions:
Stability control2
Spin control and active yaw control
Engine drag control
WARNING
The Electronic Stability Control systemESC is supplementary driver supportintended to facilitate driving and make itsafer – it cannot handle all situations inall traffic, weather and road conditions.
ESC is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
Stability control 2
This function helps control the driving and brak-ing force of each individual wheel in an attemptto stabilize the vehicle.
Spin control and active yaw control
This function is active at low speeds and brakesthe wheels that are spinning to transfer additionalpower from wheels that are not spinning.
This function also helps prevent the wheels fromspinning while the vehicle is accelerating.
1Electronic Stability Control2Also called traction control.

Engine drag control
Engine drag control (EDC3) helps prevent inad-vertent wheel lock, e.g. after downshifting orusing engine braking when driving at low speedson a slippery surface.
Inadvertent wheel lock while driving could impairthe driver's ability to steer the vehicle.

Electronic Stability Control Sportmode
The ESC4 system is always activated and can-not be switched off. However, the driver canselect ESC Sport Mode, which offers moreactive driving characteristics.
With the ESC Sport Mode sub-functionselected, intervention from ESC is reduced andmore lateral movement is permitted, giving thedriver more control of the vehicle than usual.
When ESC Sport Mode is selected, ESC mayseem to be disabled even though the functioncontinues to assist the driver.
ESC Sport Mode also helps provide maximumtraction if the vehicle gets stuck or is driving on aloose surface such as deep snow or loose sand.

Activating/deactivating Sport modein Electronic Stability Control
The ESC5 system is always activated and can-not be switched off. However, the driver canselect Sport mode, which offers more activedriving characteristics.
Sport mode can be activated/deactivated in the center dis-play's Function view.
–Tap the ESC Sport Mode button in Func-tion view.
> Sport mode is activated when the indica-tor light is green, and deactivated whenthe indicator light is gray.
When ESC Sport Mode is activated,this symbol will illuminate with a steadyglow in the instrument panel. It willremain on until the driver deactivatesthe function or until the engine is turned off. TheESC system will return to normal mode the nexttime the engine is started.

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.

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.

The Speed Limiter (SL9) function must beselected and activated in order to regulatespeed.
Putting Speed Limiter in standby mode
Note: This illustration is general and details may varydepending on model.
–Press ◀ (1) or ▶ (3) and scroll to the Speed
Limiter function (4).
> The symbol (4) will appear, indicating thatthe Speed Limiter is in standby mode.
Starting the Speed Limiter
The Speed Limiter can only be activated whilethe engine is running. The lowest maximumspeed that can be set is 30 km/h (20 mph).
–With the Speed Limiter in standby mode and
the symbol displayed, press the
button (2) on the steering wheel key-pad.
> The Speed Limiter will be started and thevehicle's current speed will be set as themaximum speed.

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.
