Emergency braking
In an emergency, the parking brake can be activated when the vehicle is moving by pull-ing and holding up the control. The brakingprocess is canceled when the control isreleased or if the accelerator pedal isdepressed.
NOTE
In case of emergency braking at high speeds, a signal sounds during the brakeprocedure.
Deactivating the parking brake
Deactivating manually
1. Depress the brake pedal firmly.2. Press the control.
> The parking brake will release and thesymbol in the instrument panel will go out.
Deactivating automatically
1. Start the vehicle.
2. Depress the brake pedal firmly. Move the gear selector to D or R and press the
accelerator pedal.
> The parking brake will release and the symbol in the instrument panel will go out.
NOTE
For automatic deactivation to be possible, the driver's seat belt must be buckled orthe driver's door closed.

Parking on a hillAlways use the parking brake when parking on a hill.
WARNING
Always apply the parking brake when park- ing on an incline. Selecting a gear or put-ting the automatic transmission in P may
not be sufficient to keep the vehicle sta-tionary in all situations.
If the vehicle is pointing uphill:
Turn the front wheels so they are pointing away from
the curb.
If the vehicle is pointing downhill:
Turn the front wheels so they are pointingtoward
the curb.
Heavy load uphill
Heavy loads, such as a trailer, could cause the vehicle to roll backward when the parkingbrake is released automatically on steep uphillgradients. To help avoid this, pull the controlupward while you are driving away. Releasethe control when the vehicle gains traction.

Parking brake malfunction
If you are unable to deactivate or activate the parking brake after several attempts, contactan authorized Volvo workshop.
A audible warning signal will sound if the park- ing brake is activated while the vehicle isbeing driven. If the vehicle must be parked before the prob- lem is rectified, turn the wheels as when park-ing on an incline and put the gear selector inP .
Low battery charge levelIf the battery charge level is too low, it will notbe possible to activate or deactivate the park-ing brake. Connect an auxiliary battery to thevehicle if the battery is discharged.
Replacing brake padsDue to the design of the electric parkingbrake, the rear brake pads must be replacedby a workshop. An authorized Volvo workshopis recommended.

Auto-hold brakes
With the Auto-hold brake function, the driver can release the brake pedal and the brakeswill remain applied, for example, when thevehicle has stopped at a traffic light or inter-section.
When the vehicle stops, the brakes are acti- vated automatically. The function can useeither the normal brakes or the parking brakesto keep the vehicle stationary and works onflat surfaces or hills. If the driver has their seatbelt fastened or if the driver's door is closed,the brakes will disengage automatically whenthe vehicle starts driving.
NOTE
When braking to a stop on an uphill or downhill gradient, depress the brake pedalwith slightly more force than usual beforereleasing to ensure that the vehicle cannotmove at all.
The parking brake is activated if
the vehicle is switched off
the driver's door is opened
the driver's seat belt is removed
the vehicle has been stationary for a pro- longed period of time (5-10 minutes)

Activating and deactivating Auto- hold at a standstill
The Auto-hold brake function at a standstill is activated with the button in the tunnel con-sole.
–Press the button in the tunnel console to activate or deactivate the function.
> The indicator light in the button will illu- minate when the function is activated. The function will remain active the nexttime the vehicle is started.
When shutting offIf the function is active and holdingthe vehicle stationary using the nor-mal brakes (A symbol lit in theinstrument panel), the brake pedal
must be depressed while pressing the buttonin order to deactivate Auto-hold.
The function will remain off until it is reac- tivated.
When Auto-hold is switched off, Hill StartAssist (HSA) will remain active to helpprevent the vehicle from rolling backwardwhen starting up a hill.

Hill Start Assist
The function for assisting when starting the vehicle on inclines (HSA 4
) helps prevent the
vehicle from rolling backward when starting on an uphill gradient. When backing up a hill,HSA helps prevent the vehicle from rollingforward.
The function retains pressure from the brake pedal in the brake system for several secondsafter the brake pedal has been released. This temporary braking effect is released after a few seconds or when the driver begins driv-ing. Hill Start Assist is available even when the Auto-hold brake function is switched off.

Braking assist after a collision
In a collision in which the activation level is reached for the pyrotechnic seat belt tension-ers or airbags, or if a collision with a large ani-mal is detected, the vehicle's brakes will beautomatically activated. This function isintended to help prevent or reduce the effectsof any subsequent collision.
After a serious collision, it may no longer be possible to control and steer the vehicle. Inorder to avoid or mitigate a possible furthercollision with a vehicle or an object in the vehi-cle's path, the brake assist system is activatedautomatically to help stop the vehicle safely. If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the drivercan override the system by depressing theaccelerator pedal. This function assumes that the brake system is intact after a collision.

Transmission
The transmission is part of the vehicle's drive- line (power transmission) between the engineand the drive wheels. The function of thetransmission is to change gears dependingon speed and power needs.
The vehicle has an 8-speed automatic trans- mission. The number of gears allows theengine's torque and power band to be effec-tively utilized. Two of the gears are overdrivegears that save fuel when driving at a constantengine speed. Manual shifting is also possible.The instrument panel shows the gear currentlyin use.

Automatic transmission
In vehicles with an automatic transmission, the system selects the gear so that drivingwill be as energy-efficient as possible. Thetransmission also has a manual mode.
The transmission is available in different ver- sions. The gear selector indicates which trans-mission the vehicle has. The various gearselectors have different functions.

The instrument panel shows which gear is cur- rently in use: P , R , N , D or M. For vehicles with the small
gear selector, P position is electric and the
gear shift pattern is instead R, N , D or M.
For manual shifting, the gear indicator in the instrument panel displays the gear currentlybeing used.
CAUTION
Check the operating temperature of the transmission to help avoid damage to anyof the drive system components. If there isa risk of overheating, a warning symbol willappear in the instrument panel and a textmessage will be displayed. Follow the rec-ommendations given.

Gear selector positions for automatic transmissions
With an automatic transmission, a suitable gear is selected automatically according tocurrent speed and power requirements.
Selecting gearsThe gear selector is a shift-by-wire selector, where shifting is done electronically instead ofmechanically. This makes shifting easier andthe gear positions more distinct.

To park a vehicle with an unbuckled seat beltand open door – end P mode by shifting to R
or D again.
The system will not automatically shift to P if
the ignition is switched off while the gearselector is in the neutral position (N). This is tomake it possible to wash the vehicle in anautomatic car wash in which the vehicle ispulled forward on rolling wheels.
Reverse - R
Select R when backing up. The vehicle must
be stationary when Reverse is selected.
Neutral - N
No gear is selected and the engine can be started. Apply the parking brake if the vehicleis stationary with the gear selector in N.
To move the gear selector from N to another
gear, the brake pedal must be depressed andthe ignition in mode II. For vehicles with the small gear selector, the engine must be run-ning.
D
drive mode
D is the normal driving gear position. The
transmission shifts up or down automatically depending on acceleration and speed. The vehicle must be stationary when the gear selector is moved from R to D.
Manual shifting mode - M
Overview of gear shift pattern in the instrument panel for large gear selector.
Manual shifting mode can be selected at any time during a drive. Engine braking will occurwhen the accelerator pedal is released. Select manual shifting mode by moving the gear selector sideways from D to ±. The cur- rent gear will be displayed in the instrumentpanel.
