Releasing the electric parking brake
Parking brake control
Manual release1. Fasten the seat belt.
2. Insert the remote key in the ignition slotand press the START/STOP ENGINE
button (or press the START/STOP
ENGINE button with a valid remote key in the passenger compartment on vehicles with the optional keyless drive).
3. Press firmly on the brake pedal.
4. Pull the parking brake control.
Automatic release1. Start the engine.
NOTE
• For safety reasons, the parking brake is only released automatically if the engineis running and the driver is wearing aseat belt.
• The electric parking brake will bereleased immediately when the acceler-ator pedal is pressed and the gearselector is in position
D or R.
2. Fasten the seat belt.
3. Move the gear selector to position D or R
and press the accelerator pedal. The parking brake will release when the vehi฀ cle begins to move.
Heavy load uphillA heavy load, such as a trailer, can cause the vehicle to roll backward when the parkingbrake is released automatically on a steepincline. To help avoid this:
1. Keep the electric parking brake lever
pushed in with the left hand while shifting into Drive with the right.
2. While pressing the accelerator pedal to pull away, release the parking brake leveronly after the vehicle begins to move.

"Message"Read the message in the information display
A flashing symbol indicates that the parking brake is being applied. If the symbol flashes in any other situation then this means that a fault has arisen. Read the message on the information display.

-Park brake not fully releasedA fault is preventing the parking brake from being released. Try to apply the parking brake and release it sev- eral times. If the problem persists, contact an authorized Volvo workshop. If you drive off with this error mes-sage showing, a warning signal sounds.
-Parking brake not appliedA fault is preventing the parking brake from being applied. Try to apply the parking brake and release it several times. If the problem persists, contact an authorized Volvo workshop. If you drive off with this error messageshowing, a warning signal sounds.
-Parking brake Service requiredA fault has occurred. Try to apply and release. Contact a Volvo workshop if the fault remains
WARNING
If the vehicle must be parked before the fault has been corrected, always put thegear selector in P and turn the wheels so
that they point away from the curb if thevehicle is pointing uphill or toward the curbif it is pointing downhill.

Hill Descent Control (HDC)*

* Option/accessory, for more information, see Introduction.137
Introduction
Normally, when the accelerator pedal is released while driving down hills, the vehicle'sspeed slows as the engine runs at lower rpm(the normal engine braking effect). However, ifthe downhill gradient becomes steeper and ifthe vehicle is carrying a load, speed increasesdespite the engine braking effect. In this sit-uation, the brakes must be applied to reducethe vehicle's speed. HDC is a type of automatic engine brake and makes it possible to increase or decrease thevehicle's speed on downhill gradients usingonly the accelerator pedal, without applyingthe brakes. The brake system functions auto-matically to maintain a low and steady speed. 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. Thedriver has full responsibility for driving in asafe manner.
Function
• HDC can be switched on and off with the button in the center console. An indicatorlight in the button illuminates when HDCis activated.
• The indicator light
in the instru-
ment panel illuminates and a message is displayed when the system is controllingthe vehicle's speed.
• HDC only functions when
first or reverse
gears are selected (
1 will be shown in the
instrument panel display when first gear is selected).
NOTE
HDC cannot be activated if the gear selec- tor is the D position.
Using HDC
HDC allows the car to roll forward at a maxi- mum speed of 6 mph (10 km/h), and 4 mph(7 km/h) in reverse. However, the acceleratorpedal can be used to select any speed that ispossible in first or reverse gears. When theaccelerator pedal is released, speed isquickly reduced again to 6 mph (10 km/h) or4 mph (7 km/h), depending on the gearselected, regardless of the hill's gradient. It isnot necessary to apply the brakes.
• The brake lights illuminate automatically when HDC is controlling the vehicle'sspeed.
• The driver can slow or stop the vehicle atany time by applying the brakes.
HDC is deactivated when:
• The button on the center console ispressed
• A gear higher than first gear is selected
• D
is selected on vehicles with an auto-
matic transmission
HDC can be deactivated at any time. If this is done while driving down a steep hill, the sys-tem's braking effect will decrease gradually.

Introduction
The Dynamic Stability and Traction Control system (DSTC) consists of a number of func-tions designed to help reduce wheel spin,counteract skidding, and to generally helpimprove directional stability.
CAUTION
A pulsating sound will be audible when the system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel spin by transferring power from a drivewheel that begins to lose traction to thewheel on the opposite side of the vehicle (onthe same axle). TC is most active at low speeds.This is one of DSTC's permanent functions and cannot be switched off.
Active Yaw Control (AYC)This function helps maintain directional stabil-ity, for example when cornering, by brakingone or more of the wheels if the vehicleshows a tendency to skid or slide laterally.This is one of DSTC's permanent functionsand cannot be switched off.
Spin control (SC)The spin control function is designed to helpprevent the drive wheels from spinning whilethe vehicle is accelerating.
Trailer Stability Assist – TSA
1Trailer Stability Assist helps stabilize a vehiclethat is towing a trailer when the vehicle andtrailer have begun to sway. See page 295 formore information. This system is automatically deactivated if the driver selects
Sport mode.
Operation
Sport modeThe stability system is always activated and cannot be switched off. However, the driver can select Sport mode,
which offers more active driving characteris- tics. In this mode, the engine managementsystem monitors movement of the acceleratorpedal and steering wheel for sportier driving by allowing more lateral movement of the rearwheels before DSTC is activated. Under certain circumstances, such as when driving with snow chains, or driving in deepsnow or loose sand, it may be advisable totemporarily use
Sport mode for maximum
tractive force. If the driver releases pressure on the acceler- ator pedal, DSTC will also activate to helpstabilize the vehicle. To switch to Sport mode:
1. Press the My Car button in the center
console control panel and select
My
XC70
DSTC in the menu.
2. Unselect the symbol and leave the menu by pressing EXIT.
> This puts DSTC in Sport mode.
Sport mode remains active until the driver
switches it off in the menu or until the engine is switched off. DSTC will return to normalmode when the engine is restarted.
