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 fromoverheating, select P or N when idling ata standstill for prolonged periods of time.

Ignition modes
The vehicle's ignition can be put in variousmodes (levels) to make different functions availa-ble.
To enable the use of a limited number of func-tions when the engine is not running, the ignitioncan be put in one of three different levels: 0, Iand II. These levels are referred to as "ignitionmodes" in the Owner's Manual.
The following table shows which functions areavailable in each ignition mode:
Mode Functions
0The odometer, clock and tem-
perature gauge are illuminatedA.
The power* seats can beadjusted.
The power windows can be used.
The center display is activated
and can be usedA.
The infotainment system can be
usedA.
In this mode, the functions are availa-ble for a limited time and then switchoff automatically.
IThe panoramic roof, power win-dows, 12-volt electrical socket inthe passenger compartment,Bluetooth, navigation, phone,blower and windshield wipers canbe used.
The power seats can be adjusted.
The 12-volt electrical socket* inthe trunk can be used.
Electrical current will be takenfrom the battery in this ignitionmode.
Mode Functions
IIThe headlights illuminate.
Warning/indicator lights illumi-nate for 5 seconds.
A number of other systems areactivated. However, seat and rearwindow heating can only be acti-vated when the engine is running.
This ignition mode uses a lot ofcurrent from the battery andshould be avoided whenever pos-sible!

Brake functions
The vehicle's brakes are used to reduce speedor prevent the vehicle from rolling.
In addition to the wheel brakes and parkingbrakes, 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, thefollowing brake assist functions may be included:
Auto-hold brakes (Auto Hold)
Hill Start Assist (Hill Start Assist)
Braking assist after a collision

Battery drain
The electrical functions in the vehicle drain thebattery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Useignition mode I instead, as this uses less electri-cal current.
Note that certain accessories may also drainpower from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audiosystem.
–Charge the battery by starting the engineand let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

Jump starting using another battery
If the start battery is discharged, current fromanother battery can be used to start the vehicle.
Jumper cable connecting points.
CAUTION
The charging point of the vehicle is onlyintended for jump starting the vehicle in ques-tion. The charging point is not intended forjump-starting another vehicle. Using thecharging point to start another vehicle couldcause a fuse to blow, which would cause thecharging point to stop working.
If a fuse has blown, 12 V Battery Fuse failureService required will be displayed in the instru-ment panel. Volvo recommends contacting anauthorized Volvo workshop.
To avoid short circuits or other damage, the fol-lowing steps are recommended when jump star-ting the battery:

STARTING AND DRIVING

1.Put the ignition in mode 0.
2.Make sure the auxiliary battery (the batteryused to jump start the discharged battery)has a voltage of 12 volts.
3.If the auxiliary battery is in another vehicle,turn off that vehicle's engine and make surethat the vehicles are not touching each other.
4. Clamp the red jumper cable onto the auxiliarybattery's positive (+) terminal (1).

CAUTION
Connect the jump cable carefully to preventshort circuits with other components in theengine compartment.
5. Fold back the cover over your vehicle's posi-tive (+) jump start terminal (2).
6. Clamp the other end of the red jumper cableto your vehicle's positive (+) jump start termi-nal (2).
7.Clamp the black jumper cable onto the auxili-ary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumpercable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securelyattached to help prevent sparks while jumpstarting.
10. Start the engine of the assisting vehicle andlet it run for a few minutes at a higher idlingspeed than normal, about 1500 rpm.
11. Start your vehicle's engine. If the enginedoes not start, allow an additional 10minutes of charging time and then try to startthe engine again.
NOTE
When the engine is started under normalconditions, the vehicle's electrical drive motoris prioritized – the gasoline engine remainsoff. This means that the electric motor has"started" and the vehicle is ready to be drivenonce the start knob has been turned clock-wise. Start of the electric motor is indicatedby the indicator lights on the instrument panelgoing out and its preselected theme illuminat-ing.

CAUTION
Do not touch the connections between thecable and the vehicle during the start attempt.Risk of sparking.
12. Remove the jumper cables in the reverseorder ‒ first the black cables and then thered cables.
Make sure that none of the clamps of theblack jumper cables come into contact witheither vehicle's positive (+) jump start termi-nals or either of the red jumper cable's con-nected clamps.
