Hill Start Assist
The function for assisting when starting the vehi-cle on inclines, Hill Start Assist (HSA), helpsprevent the vehicle from rolling backward whenstarting on an uphill gradient. When backing upa hill, HSA helps prevent the vehicle from rollingforward.
The function retains pressure from the brakepedal in the brake system for several secondsafter the brake pedal has been released.
This temporary braking effect is released after afew seconds or when the driver begins driving.
Hill Start Assist is available even if the Auto-holdbrake function is switched off.

Braking assist after a collision
In a collision in which the activation level isreached for the pyrotechnic seat belt tensionersor airbags, or if a collision with a large animal isdetected, the vehicle's brakes will be automati-cally activated. This function is intended to helpprevent or reduce the effects of any subsequentcollision.
After a serious collision, it may no longer be pos-sible to control and steer the vehicle. In order toavoid or mitigate a possible further collision witha vehicle or an object in the vehicle's path, thebrake assist system is activated automatically tohelp stop the vehicle safely.
The brake lights and hazard warning flashers areactivated during braking. When the vehicle hasstopped, the hazard warning flashers will con-tinue to flash and the parking brake will beapplied.
If braking is not appropriate, e.g. if there is a riskof being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal.
This function assumes that the brake system isintact after a collision.
Brake assist is part of the Rear Collision Warningand Blind Spot Information safety systems.

Drive systems
Volvo Twin Engine combines a combustionengine for the front wheels and an electric motorfor the rear wheels.

Two drive systems
Depending on the selected drive mode andpower available in the electric motor, the drivesystems can either be used separately or in tan-dem.
The electric motor gets its energy from a hybridbattery located under the tunnel console. Thehybrid can be charged from a wall outlet or in aspecial charging station. The combustion enginecan also charge the hybrid battery using a specialhigh-voltage generator.
Both the combustion engine and the electricmotor can generate power directly to the wheels.An advanced control system coordinates both thedrive systems to help optimize driving economy.
Hybrid battery - The hybrid battery's functionis to store electrical current. This energy isprovided by plugging the charging cable intoan electrical outlet, through regenerativebraking or from the high-voltage generator.This provides current to power the electricmotor and to temporarily power the electricalair conditioning to precondition the passen-ger compartment.
Combustion engine - The combustion enginestarts when the charge level in the hybridbattery is too low to provide the power outputrequested by the driver.
High-voltage generator2 - Charges the hybridbattery. Starter for the combustion engine.
Can provide the combustion engine withextra electrical current.
Electric motor - Powers the vehicle usingelectricity. Can provide extra torque andpower during acceleration. Provides electricalall-wheel drive functionality. Regeneratesbraking energy into electrical current.

Starting and stopping thecombustion engine in Twin Enginevehicles
An advanced control system determines the dis-tance that the vehicle can be driven on the com-bustion engine, electric motor, or both at thesame time. When driving on only the electricmotor, the vehicle may automatically start thecombustion engine due to outside circumstan-ces, e.g. low ambient temperatures. This is com-pletely normal. The combustion engine will alsoalways start when the hybrid battery is nearlyfully discharged.

Climate settings at low temperatures
At low ambient temperatures, the combustionengine will sometimes start automatically to helpachieve the desired passenger compartmenttemperature and air quality. The amount of timethe combustion engine is running can be affec-ted by:
lowering the temperature
reducing blower speed
activating Pure drive mode.

Using the electric motor in hot or cold
weather
At very low or high ambient temperatures, theelectric motor's driving range and power may bereduced and affect how often the combustionengine automatically starts.
Emission control system
To help ensure that the emission control systemfunctions optimally, the combustion engine willrun for several minutes after it is started. Theamount of time the combustion engine needs tobe used varies depending on the temperature ofthe three-way catalytic converter.

Low Speed Control
The low-speed function, Low Speed Control(LSC), facilitates and improves control and trac-tion on rough roads and slippery surfaces, e.g.when towing a trailer on grass or up boat ramps.
The function is included in the Off Road drivemode.
Low Speed Control is designed for driving onrough roads and when towing trailers at lowspeeds, up to approximately 40 km/h (25 mph).
When driving at low speeds, LSC prioritizes lowgears and all-wheel drive to help avoid wheel spinand improve traction on all wheels. The accelera-tor pedal will be less responsive to improve trac-tion and speed control at low speeds.
The function is activated together with HillDescent Control (HDC), which makes it possibleto control speed going down steep hills using theaccelerator pedal and reduces the need to usethe brake pedal. The system makes it possible tomaintain a low and uniform speed when drivingdown steep hills.

Hill Descent Control
The function for assisting when driving downhill,Hill Descent Control (HDC), is a low-speedfunction with increased engine braking. Thefunction makes it possible to increase ordecrease the vehicle's speed on steep downhillgradients by only using the accelerator pedal,without applying the brakes.
The function is included in the Off Road drivemode.
HDC is designed for driving on rough roads atlow speeds and downhill gradients with slipperyor otherwise difficult road surfaces. The driverdoes not need to use the brake pedal but caninstead focus on steering.

WARNING
HDC is only intended to be a supplementarybraking aid and it does not function in all sit-uations.
The driver is always ultimately responsible foroperating the vehicle in a safe manner.

Function
Hill Descent Control allows the vehicle to moveforward or backward at very low speeds assistedby the brake system. The driver can increase thespeed by pressing the accelerator pedal. Whenthe accelerator pedal is released, the vehicle willreturn to very low speed regardless of how steep
the hill is and without the brakes needing to beapplied. The brake lights will illuminate when thefunction is activated.
The driver can brake to stop or slow the vehicleat any time by depressing the brake pedal.
HDC is activated along with Low Speed Control(LSC), which facilitates and improves traction andcontrol on rough and slippery surfaces. The sys-tem is intended to be used at low speeds, up toapproximately 40 km/h (25 mph).
To keep in mind when using HDC
If the function is switched off while driving ona steep downhill gradient, braking effect willbe gradually reduced.
HDC can be used in gear positions D and R,and in manual gears 1 or 2.
It is not possible to manually shift to thirdgear or higher when HDC is active.

NOTE
When LSC with HDC is activated in the OFFROAD drive mode, the feel of the acceleratorpedal and engine response will change.

NOTE
This drive mode is not designed to be usedfor normal street driving.
NOTE
The function is deactivated when driving athigh speeds and must be reactivated at lowerspeeds if so desired.
