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 parking brake, 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

Auto-hold brake function
With the Auto-hold brake function, the driver can release the brake pedal and the brakes willremain applied, for example, when the vehiclehas stopped at a traffic light or intersection.
When the vehicle is no longer moving forward, Auto-hold applies the brakes automatically, eitherusing the normal brakes or the parking brake.The brakes will be released when the acceleratorpedal is depressed. If the driver's door is opened or the engine is turned off, the parking brake will be applied auto-matically.
Auto-hold control
Auto-hold control and indicator light
Turn Auto-hold on or off by pressing the control in the tunnel console. The indicator light illumi-nates when the function is on. When Auto-hold is off, Hill Start Assist (HSA) willbe activated to help prevent the vehicle from roll-ing backwards when starting up a hill.

Brake assist system
The Brake Assist System (BAS) increases brak- ing force, thereby helping reduce braking dis-tance. The system monitors the driver's braking habits and increases braking force when necessary.Brake force can be increased up to the point atwhich the ABS system is activated. The functionis deactivated when pressure on the brake pedaldecreases.

Braking effect after a collisionIn certain types of collisions, the vehicle's brakes are applied to help prevent or mitigate a secon-dary collision.
Maintaining control of the vehicle after a collision may 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 will be 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 not be desirable, the driver can override this systemby pressing the accelerator pedal. This feature can only function if the brake system is intact after the collision.

• Rear Collision Warning (RCW) (p. 292)
Emergency brake lights
The emergency brake lights activate in the event of 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.

• Hazard warning flashers (p. 147)
• Brake lights (p. 146)
Hill Descent Control (HDC) HDC is a type of low-speed automatic engine brake 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 drive
mode.
HDC is particularly useful when driving down steep hills with rough surfaces, and where theroad may have slippery patches.
WARNING
HDC does not function in all situations, and is a supplementary braking aid. The driver hasfull responsibility for driving in a safe manner.
FunctionHDC allows the vehicle to roll forward or in reverse 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 the vehicle at any time. HDC is activated along with Low Speed Control (LSC), which together make driving on slipperysurfaces at low speeds easier.

Driving with a trailer
When towing a trailer, always observe the legal requirements of the state/province.
• All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par- ticular problems, but take into consideration:
• Increase tire pressure to recommended full pressure.
• When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
• If the automatic transmission begins to over-heat, a message will be displayed in the textwindow.
• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy.
• It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safe stop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.
NOTE
• When parking the vehicle with a trailer on a hill, apply the parking brake before put- ting the gear selector in
P. Always follow
the trailer manufacturer's recommenda- tions for wheel chocking.
• When starting on a hill, put the gear selector in
D before releasing the parking
brake.
• If you use the manual (Geartronic) shift positions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
• The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
• Avoid driving with a trailer on inclines ofmore than 15%.

Using the electric motor in city driving A number of factors affect the electric motor's driving range.
The driver can affect some of these factors while others depend on outside conditions such astemperature, road surface, etc.
Factors that determine the electric motor's driving range
Factors outside of the driver's control
The following are examples of factors that the driver cannot control:
• The current traffic situation
• Driving short distances
• Topography
• Ambient temperature and headwinds
• Road conditions/road surface
The following table shows the approximate rela-
tionship between ambient temperature and driv-ing range using the electric motor (with reducedclimate system functionality). Warmer tempera-tures increase driving range.
77 °F (25 °C)105%
68 °F (20 °C)100%
50 °F (10 °C)90%
40 °F (5 °C)85%
32 °F (0 °C)80%
23 °F (-5 °C)75%
14 °F (-10 °C)70%
Factors in the driver's control
The driver should be aware of the following fac- tors in order to utilize the vehicle's electric motormost efficiently:
• Charge the hybrid battery regularly
• Preconditioning
• The
Pure drive mode
• Climate system settings
• Speed and acceleration
• The
Save drive mode
• Tires and inflation pressure
The following table shows the approximate rela-
tionship between constant speed and driving range where driving at a lower constant speedhelps increase the electric motor's driving range.
62 mph (100 km/h)70%
55 mph (90 km/h)80%
50 mph(80 km/h)90%
43 mph (70 km/h)100%
37 mph (60 km/h)110%
30 mph(50 km/h)120%
NOTE
• The figures in the preceding tables per- tain to a new vehicle.
• None of the figures are absolute and areaffected by e.g., driving style, weather,traffic conditions, etc.
Driving with the electric motorUse the Pure drive mode for the most energy-
efficient driving to help maximize driving range using the electric motor only. Use the
Save drive mode for higher speeds
when driving farther than is possible using the electric motor only.

All Wheel Drive (AWD) 8
Your Volvo can be equipped with All Wheel Drive, which means that power is distributedautomatically between the front and rear wheels.
Under normal driving conditions, most of the engine's power is directed to the front wheels.However, if there is any tendency for the frontwheels to spin, an electronically controlled cou-pling distributes power to the wheels that havethe best traction. AWD reacts differently, depending on the drive mode * selected.

Suspension and leveling control
*
The leveling control system adjusts the suspen- sion and shock absorbers automatically to helpprovide good comfort and control while driving.Leveling can also be controlled manually tomake loading or getting in and out of the vehicleeasier.
Pneumatic suspension and shock absorbers
This system is linked to the selected drive mode and is adapted to the vehicle's speed. The pneu-matic suspension reduces the vehicle's groundclearance at higher speeds to reduce wind resis-tance and increase stability. The shock absorbersare normally set to provide the best possiblecomfort and are adjusted continuously accordingto the road surface, acceleration, braking andcornering. A message will be displayed in the instrument panel when the suspension level is beingadjusted. The level cannot be adjusted if one of the side doors or the hood is open.
