Brake functions
The vehicle's standard braking features are aug-mented by a number of auxiliary help functions.
In addition to the wheel brakes and the parkingbrake, the vehicle is equipped with several auto-matic brake assist functions. These systems helpthe driver by e.g., keeping the vehicle stationarywhen the brake pedal is not depressed (at a traf-fic light or intersection), when starting up a hill orwhen driving down a hill.
These systems include:
•Auto-hold brakes
•Hill Start Assist
•Braking assist after a collision
•Hill Descent Control*

Braking effect after a collision
In certain types of collisions, the vehicle's brakesare applied to help prevent or mitigate a secon-dary collision.
Maintaining control of the vehicle after a collisionmay be difficult. To help avoid or mitigate theeffect of a secondary collision, the brakes areapplied automatically to help bring the vehicle toa stop.
The brake lights and hazard warning flashers willbe activated and the flashers will remain on afterthe vehicle has come to a standstill. The parkingbrake will then be applied automatically.
In a situation where stopping the vehicle may notbe desirable, the driver can override this systemby pressing the accelerator pedal.
This feature can only function if the brake systemis intact after the collision.

•Rear Collision Warning (RCW) (p. 338)
Emergency brake lights
The emergency brake lights activate in the eventof hard braking/rapid deceleration at most nor-mal driving speeds or if the ABS system is acti-vated. This function causes an additional taillighton each side of the vehicle to illuminate to helpalert vehicles traveling behind.
Once the emergency brake lights have been acti-vated, if the driver releases the brake pedal, thebrake lights will return to their normal function.

Hill Descent Control (HDC)
HDC is a type of low-speed automatic enginebrake and makes it possible to increase ordecrease the vehicle's speed on steep downhillgradients using only the accelerator pedal, with-out applying the brakes.
HDC is integrated into the Off Road drivemode.
HDC is particularly useful when driving downsteep hills with rough surfaces, and where theroad may have slippery patches.

WARNING
HDC does not function in all situations, and isa supplementary braking aid. The driver hasfull responsibility for driving in a safe manner.

Function
HDC allows the vehicle to roll forward or inreverse at very low speed with enhanced enginebraking. However, speed can be adjusted withthe accelerator pedal. When the acceleratorpedal is released, the vehicle will return to verylow speed.
The driver can use the brakes to slow or stop thevehicle at any time.
HDC is activated along with Low Speed Control(LSC), which together make driving on slipperysurfaces at low speeds easier.

STARTING AND DRIVING
* Option/accessory, for more information, see Introduction.381
When HDC and LSC are activated, this changesthe response from the accelerator pedal andengine.

Activating HDC
This function can be activated in different ways,depending on how the vehicle is equipped.

Using the drive mode control *
Select the Off Road drive mode to activate thefunction.
Select a different drive mode to turn HDC off. Ifthis is done while the vehicle is on a steep down-grade, engine braking will decrease gradually.
From the center display's Function view
Models without the drive modecontrol have a button for HillDescent Control in the centerdisplay's Function view.
•Tap the button to activate. A light in the but-ton illuminates when the function is acti-vated.

NOTE
The function is deactivated when driving athigher speeds and must be reactivated atlower speeds if so desired.

Hill Start Assist
Hill Start Assist (HSA) helps prevent the vehiclefrom rolling backwards when starting up a hill. Ifyou are backing up a hill, HSA helps prevent thevehicle from rolling forward.
HSA makes it easier to start or back up on a hillby retaining pressure on the brake pedal for sev-eral seconds after the pedal has been released inorder to keep the vehicle at a standstill.
The brakes will be released after several secondsor when the driver presses the accelerator pedal.
HSA is available even if the Auto-hold brakingfunction is turned off.

Preconditioning
•If possible, precondition the vehicle with thecharging cable before driving.
•Avoid parking the vehicle so that the passen-ger compartment becomes too hot or cold.Park, if possible, in a climate controlled park-ing garage.
•For short drives after using the precondition-ing function, turn off the climate systemblower if possible.
•If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reduces thehybrid battery's charge level.

Driving
•Choose the Pure drive mode to help mini-mize electric power consumption.
•Maintain a constant speed and an adequatedistance to the vehicle ahead to minimizeuse of the brakes.
•Brake as gently as possible; doing socharges the hybrid battery using the inte-grated regenerative braking function.
•Balance energy requirements using theaccelerator pedal and utilize the gauge onthe instrument panel to see the amount ofpower available from the electric motor. Thishelps avoid starting the gasoline engineunnecessarily. The electric motor is more
energy-efficient than the gasoline engine,especially at lower speeds.
•In hilly terrain, put the gear selector in modeB to utilize the electric motor's braking func-tion when the accelerator pedal is released.This helps charge the hybrid battery.
•Higher speeds increase energy consumptionand the vehicle's wind resistance increasesalong with speed. Do not exceed postedspeed limits.
•Avoid carrying unnecessary items (extra load)in the vehicle.
•Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold).
•Remove snow tires when threat of snow orice has ended.
•Note that roof racks, ski racks, etc, increaseair resistance and also energy consumption.
•Avoid driving with open windows.

Handling and roadholding
•Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so thatcapacity weight or maximum permissible axleloads are not exceeded.
•At the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned more
than might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alterwith the vehicle load. The heavier the load inthe cargo compartment, the less the ten-dency to understeer.

Driving through standing water
The vehicle should be driven with extreme cau-tion if it is necessary to drive through standingwater.
The vehicle can be driven through water up to adepth approximately level with the floor at walk-ing speed to help prevent water from enteringthe differential and/or the transmission or dam-aging electrical components.
•If possible, check the depth of the waterbefore driving through it. Take particular carewhen driving through flowing water.
•Before driving through water, always selectthe Off Road drive mode to ensure that thegasoline engine is running and to maximizeground clearance.
•After driving through water, apply the brakesand check that they are functioning correctly.
•Clean the electrical connections for trailerwiring after driving in mud or water.
•When driving through water, maintain lowspeed and do not stop in the water.

CAUTION
•Damage may occur to the engine, trans-mission, electrical components, etc. if thevehicle is driven through water higherthan its floor level. Be aware that wavescreated by other vehicles could cause thelevel to temporarily be above the vehicle'sfloor level.
•Damage to any components due to waterabove the floor level, vapor lock or insuffi-cient oil is not covered under warranty.
•If the engine has been stopped while thevehicle is in water, do not attempt torestart it. Have the vehicle towed out ofthe water and inspected by a trained andqualified Volvo service technician.

WARNING
•Avoid driving through standing or rushingwater. Doing so can be dangerous and itmay also be difficult to determine theactual depth of the water.
•If water cannot be avoided, after drivingthrough the water, press lightly on thebrake pedal to ensure that the brakes arefunctioning normally. Water or mud canmake the brake linings slippery, resultingin delayed braking effect.
