KEY, LOCKS AND ALARM
* Option/accessory.
238 For keyless use, a remote key or the Key Tag must be within the shaded areas shown in theillustration, i.e. a semicircle with a radius ofapprox. 1.5 meter (5 feet) along the sides of thevehicle or approx. 1 meter (3 feet) from the tail-gate.
NOTE
The functions of the remote control key can be disrupted by ambient radio waves, build-ings, topographical conditions, etc. The vehi-cle can always be locked/unlocked using thekey blade.
If the remote key is removed from the vehicle
If the remote key is removed from the vehicle while the engine is running, the warning message
Vehicle key not
found Removed from vehicle will be
displayed in the instrument panel and an audible signal will sound when the last door is closed.
The message will disappear when the key is returned to the vehicle and the O button on the
right-side steering wheel keypad is pressed or when the last door is closed again.

Replacing the remote key's battery
The battery in the remote key must be replaced when it is discharged.
NOTE
All batteries have a limited service life and must eventually be replaced (does not applyfor Key Tag). The battery's service life variesdepending on how often the vehicle/key isused.
The remote key battery should be replaced if:
the information symbol illuminates and the message
Vehicle key bat. low
See Owner's manual is displayed in
the instrument panel
and/or
• the locks do not react after several attempts to lock or unlock the vehicle using theremote key within approx. 20 meter (65 feet)from the vehicle.
NOTE
Move closer to the vehicle and try to unlock it again.

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.

DRIVER SUPPORT
* Option/accessory.267
WARNING
While the power steering is working at reduced power, the driver support functionswith steering assistance are not available. In such a situation, the driver display shows the
Power steering failure or Power
Steering Assist Temporarily Reduced
message, combined with a STEERING WHEEL symbol.
Changing the level of steering wheel resistance *
To change the level of steering wheel resistance, see the description of the INDIVIDUAL optionunder "Available drive modes" in the "Drivemodes" section. On models not equipped with drive mode con- trols and the INDIVIDUAL option, steering wheelresistance can instead be set in the center dis-play's Top view under:
SettingsMy CarDrive ModesSteering force
Steering wheel resistance settings cannot be accessed when turning at speeds above10 km/h (6 mph).

Stability system Roll StabilityControl
The Roll Stability Control (RSC 1
) system helps
minimize the risk of a rollover in the event of e.g. a sudden evasive maneuver or if the vehiclebegins to skid.
The RSC system monitors the lateral angle at which the vehicle is leaning and registers anychanges. Using this information, the system cal-culates the likelihood of a rollover. If there is animminent risk of a rollover, Electronic StabilityControl is activated, engine torque is reduced andbrakes are applied to one or more of the wheelsuntil the vehicle has regained stability.

Electronic Stability Control
The Electronic Stability Control (ESC 2
) function
helps the driver avoid skidding and improves the vehicle's directional stability.
This symbol will be displayed in the instrument panel when theESC system is intervening. When the ESC has intervened to apply the brakes, a pulsingsound may be heard and the
vehicle may accelerate more slowly than expec-ted when the accelerator pedal is depressed.
The ESC system consists of the following sub- functions: • Stability control 3
• Spin control and active yaw control
• Engine drag control
• Trailer Stability Assist
WARNING
•The Electronic Stability Control system ESC 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 3This function helps control the driving and brak-ing force of each individual wheel in an attemptto stabilize the vehicle.
Spin control and active yaw controlThis 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 from spinning while the vehicle is accelerating.
Engine drag control
Engine drag control (EDC
4
) 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 impair the driver's ability to steer the vehicle.
Trailer Stability Assist *5
Trailer Stability Assist (TSA
6
) is designed to help
stabilize a vehicle that is towing a trailer if thevehicle and trailer have begun to sway. For moreinformation, see "Trailer Stability Assist".
NOTE
The TSA function is deactivated if ESC Sport
Mode is activated.

Some examples of symbols and messages are shown in the table below.
SymbolMessageMeaning
Steady glow for approx. 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 offThe ESC system's functionality has been temporarily reduced due to high brake system temperatures. The function will be automatically reactivated when the brakes have cooled. See the message in the instrument panel.
ESC Service requiredThe 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-side
steering wheel keypad. If the message persists: Contact a workshop

1. Depress the accelerator as far as possible and then release it when the desired speed has been reached.
> The Speed Limiter will remain activatedand the symbol in the instrument panel will be WHITE.
2. Release the accelerator pedal fully when the temporary acceleration is completed.
> The vehicle will automatically slow downto a speed below the most recently set maximum speed.
