Long-term storage of vehicles withhybrid batteries To help minimize degradation of the hybrid bat- tery if the vehicle is not driven for a prolongedperiod (longer than 1 month) the hybrid batterycharge level should be kept at approx. 25%according to the gauge in the instrument panel.
Do as follows:
1. If the hybrid battery charge level is high, drivethe vehicle until the charge level is approxi- mately 25%. If the charge level is low, chargethe battery until the level reaches approxi-mately 25%. 2. If the vehicle is not driven for more than 6
months or the hybrid battery's charge level isnoticeably below the 25% mark, charge thebattery to about 25% to help compensate forthe natural battery discharge that occurs inlong-term storage. Regularly check thecharge level using the gauge in the instru-ment display.
NOTE
Store the vehicle in as cool a location as pos- sible to minimize battery aging during long-term storage. In the summer, park the vehicleindoors or in a shady location, whichever iscooler.

In some situations, such as in cold weather or if the hybrid battery's charge level is too low, thegasoline engine will start instead. The vehicle should not be started with the charg- ing cable connected. However, if the cable can-not be pulled out or if the vehicle incorrectlydetects a cable that is not connected, the vehiclecan be started using an override procedure:
1. Press the brake pedal and turn the start
knob clockwise.
2.
Charge cable Remove before start will
appear in the instrument panel.
3. Turn the start knob clockwise again. 4.
Removed? Turn and hold start knob 7swill appear. Turn the knob clockwise and hold it for 7 seconds to start the vehicle.
Location of the backup reader in the tunnel console.
If the Vehicle key not found message is shown
in the instrument panel at start, place the remote key at the backup reader and then make a newstart attempt.
NOTE
When the remote key is placed in the backup reader, make sure that no other vehicle keys,metal objects or electronic devices (e.g. cellu-lar phones, tablets, laptops or chargers) are inthe backup reader. Multiple vehicle keys closeto each other in the backup reader can dis-rupt their functionality.
If Vehicle start System check, wait is dis-
played in the instrument panel while attempting to start the vehicle, wait until the message disap-pears and try again to start the vehicle.
CAUTION
If the engine has not responded after 3 attempts – wait for 3 minutes before startinga new attempt. Starting capability increases ifthe starter battery is given time to recover.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.
WARNING
• Always remove the remote key from the passenger compartment when you leavethe vehicle and make sure the ignition is in mode
0.
• Always put the gear selector in
P and
apply the parking brake before leaving the vehicle. Never leave the vehicle unsu-pervised while the engine is running.
• Always open the garage door fully andmake sure that ventilation is very goodbefore starting the engine in a garage.The exhaust fumes produced by the vehi-cle contain carbon monoxide, which isinvisible and odorless but very toxic.
WARNING
Never
remove the remote control key from
the vehicle while driving.
WARNING
Always take along the remote control key when leaving the vehicle and make sure thatthe vehicle electrical system is in ignition mode 0 – especially if there are children in
the vehicle.

NOTE
With a cold start, idling speed may be consid- erably higher than normal for certain enginetypes. This is done to get the emissions sys-tem up to normal operating temperature asquickly as possible, which minimizes exhaustemissions and protects the environment.
CAUTION
•When starting in cold weather, the auto- matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
• Do not race a cold engine immediatelyafter starting. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it has reachedthe proper operating temperature.
• The engine should be idling when thegear selector is moved. Never accelerateuntil the gear is fully engaged. Accelerat-ing rapidly before a gear is properlyengaged could lead to harder wear ofcomponents.
• To help prevent the transmission oil from overheating, select
P or N when idling at
a standstill for prolonged periods of time.

Brake functions
The vehicle's brakes are used to reduce speed or prevent the vehicle from rolling.
In addition to the wheel brakes and parking brakes, the vehicle is also equipped with a num-ber of automatic brake assist functions. Thesesystems help the driver by e.g. keeping the vehi-cle stationary when the brake pedal is notdepressed (e.g. at a traffic light or intersection),when starting up a hill or when driving down a hill. Depending on how the vehicle is equipped, the following brake assist functions may be included:
• Auto-hold brakes (Auto Hold)
• Hill Start Assist (Hill Start Assist)
• Braking assist after a collision
• City Safety
• Hill Descent Control (Hill Descent Control)

Brakes The brake pedal is used to apply the vehicle's regular brakes, which are part of the brake sys-tem.
The vehicle is equipped with two brake circuits. If one brake circuit is damaged, the brake pedal willgo down further when depressed. More pressurewill then be required from the driver for normalbraking effect.
WARNING
If the vehicle does not have electrical current and both the electric motor and the gasolineengine are switched off, the brakes cannot beused to stop the vehicle.
In very hilly areas or when driving with a heavy load, gear position B can be used to augment the
brakes with engine braking. Use the Off Road drive mode to increase the engine braking effect when driving on steepdowngrades at low speeds.
Anti-lock brakesThe vehicle is equipped with an Anti-lock BrakingSystem (ABS), which can help prevent thewheels from locking and help maintain steeringcontrol when braking. Vibrations may be felt fromthe brake pedal when ABS is operating, which isnormal. After the vehicle is started, a brief test of the ABS system is automatically performed when the driver releases the brake pedal. An additionalautomatic test of the system may be performedwhen the vehicle is traveling at a low speed. Dur-ing the test, the brake pedal may feel as though itis pulsating.
Light braking charges the hybrid batteryWhen the brakes are applied lightly, the electricmotor braking function is used. This converts thevehicle's kinetic energy into electrical energy,which is used to charge the hybrid battery. Whenthe battery is being charged with the electricmotor braking function, this will be indicated inthe instrument panel.
When the battery is being charged with the electric motor braking function, this will be indicated in theinstrument panel.
This function is active at speeds in the range of 150-5 km/h (93-3 mph). When braking atspeeds outside of this range, or during harderbraking, the hydraulic braking system is used to

Parking brake malfunctionIf you are unable to deactivate or activate the parking brake after several attempts, contact anauthorized Volvo workshop.
A audible warning signal will sound if the parking brake is applied while the vehicle is being driven. If the vehicle must be parked before the problem is rectified, turn the wheels as when parking on an incline and put the gear selector in P.
Low battery charge levelIf the battery charge level is too low, it will not be possible to apply or release the parking brake.Connect an auxiliary battery to the vehicle if thebattery is discharged.
Replacing brake padsDue to the design of the electric parking brake,the rear brake pads must be replaced by a work-shop. An authorized Volvo workshop is recom-mended.

440 Help functions The system will automatically shift to
P:
• if the ignition is switched off while
D or R is
selected.
• if the driver unbuckles the seat belt and opens the driver's door while the vehicle isrunning with the gear selector in a gear other than
P.
To park a vehicle with an unbuckled seat belt andopen door – end P mode by shifting to R or D
again.
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 vehicle is stationary with the gear selector in N.
To move the gear selector from Neutral to another gear, the brake pedal must be depressed and the ignition in mode II.
D drive mode
D is the normal driving gear position. The trans-
mission shifts up or down automatically depend- ing on acceleration and speed. The vehicle mustbe stationary when the gear selector is moved from R to D.
Brake - B
B can be selected at any time during a drive. In B
mode, the engine braking function is activated when the accelerator pedal is released, whichhelps charge the hybrid battery. This offers addi-tional opportunities to recharge the hybrid bat-tery, since the battery is charged even when thebrake pedal is not depressed.
B mode in the instrument panel.
From B mode, it is possible to manually shift to
lower gears. The currently selected gear (1-8) will be displayed in the instrument panel.
• Pull the gear selector backward once to shiftdown one gear.
• Pull the gear selector backward again to shiftdown to lower gears.
To shift manually to a higher gear, the vehicle must be equipped with steering wheel paddles *. •
Push the gear selector forward to return to
D
mode.
For smooth shifting and engine performance, the
transmission will shift down automatically if the vehicle's speed becomes too low for the selectedgear.
