STARTING AND DRIVING

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.

Ignition modes
The vehicle's ignition can be put in various modes (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 ignition can be put in one of three different levels: 0, I
and II. These levels are referred to as "ignition
modes" in the Owner's Manual. The following table shows which functions are available in each ignition mode:
ModeFunctions
0 •The odometer, clock and tem- perature gauge are illuminated A
.
• The power seats
* can be
adjusted.
• The power windows can be used.
• The center display is activatedand can be used A
.
• The 12 V outlet in the cargo com- partment
* can be used.
• The infotainment system can be used A
.
In this ignition mode, the functions are available for a limited time and then switch off automatically.

Battery drain The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain power 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 audio system.
–Charge the battery by starting the engine and 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 from another battery can be used to start the vehicle.
Jumper cable connecting points.
CAUTION
The charging point of the vehicle is only intended 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 failure
Service required will be displayed in the instru-
ment panel. Volvo recommends contacting an authorized Volvo workshop. To avoid short circuits or other damage, the fol-lowing steps are recommended when jump star-ting the battery:

STARTING AND DRIVING
4701.
Put the ignition in mode 0.
2. Make sure the auxiliary battery (the battery used 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 auxiliary battery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to prevent short 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 cable to 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 jumper cable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securely attached to help prevent sparks while jumpstarting. 10. Start the engine of the assisting vehicle and
let it run for a few minutes at a higher idlingspeed than normal, about 1500 rpm.
11. Start your vehicle's engine. If the engine does not start, allow an additional 10minutes of charging time and then try to startthe engine again.
NOTE
When the engine is started under normal conditions, 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 the cable and the vehicle during the start attempt.Risk of sparking.
12. Remove the jumper cables in the reverse
order ‒ first the black cables and then the
red cables. Make sure that none of the clamps of the black jumper cables come into contact witheither vehicle's positive (+) jump start termi-nals or either of the red jumper cable's con-nected clamps.

Towing using a towlineThis section refers to one vehicle being towed behind another using a towline.
Twin Engine vehicles may not be towed behind another vehicle due to the risk of damage to theelectric motor. If the vehicle cannot be driven andneeds to be moved, it must be transported on atow truck with all four wheels on the bed of thetruck.
Towing another vehicleTowing another vehicle requires a lot of power - use the AWD drive mode. This helps charge the
hybrid battery and improve the vehicle's driving and roadholding characteristics. Before towing another vehicle, check applicable speed limit regulations.
Jump startingDo not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.
CAUTION
Attempts to tow-start the vehicle could cause damage to the electrical drive motor andthree-way catalytic converter.
