Displaying trip statistics in thecenter display
Trip computer statistics can be displayed graphi-cally in the center display, providing an overviewthat facilitates more fuel-efficient driving.
Open the Driver performanceapp in the App view to displaytrip statistics.
Each bar in the graph repre-sents a driving distance of 1kilometers, 10 kilometers or100 kilometers (or miles). The bars are addedfrom the right as you drive. The bar at the far rightshows the data for the current trip.
Average fuel consumption and total driving timeare calculated from the most recent reset of thetrip statistics.
Fuel and electricity consumption are shown inseparate graphs. The electricity consumptionshows "net" consumption, i.e. consumed currentminus regenerated current generated by braking.

City Safety braking for oncomingvehicles
City Safety can help you apply the brakes for anoncoming vehicle in your lane.
If an oncoming vehicle veers into your lane and acollision is unavoidable, City Safety can helpreduce your vehicle's speed to attempt to miti-gate the force of the collision.
Own vehicle
Oncoming vehicles
The following criteria must be met for the func-tion to work:
your vehicle's speed must be above 4 km/h(3 mph)
the road must be straight
your lane must have clear side lane markings
your vehicle must be positioned straight inyour lane
the oncoming vehicle must be positionedwithin your vehicle's lane markings
the oncoming vehicle's headlights must beon
the function can only handle “front-to-front”collisions
the function can only detect vehicles withfour wheels
the function requires functioning ElectricSeat Belt Tensioners (see section “Seatbelt tensioners”).

NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".
WARNING
The "City Safety braking for oncomingvehicles" function is supplementary driversupport intended to help improve drivingsafety – it cannot handle all situations inall traffic, weather and road conditions.
Warnings and brake interventions due toan imminent collision with an oncomingvehicle always come very late.
Never wait for a collision warning or forCity Safety to intervene. If you notice anyhazard or other potentially dangerous sit-uation, always fully apply the brakes.
City Safety is not a substitute for the driv-er's attention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

STARTING AND DRIVING
444
The kickdown function
Kickdown is used when maximum acceleration isneeded, e.g. when passing.
When the accelerator pedal is depressed all theway to the floor (past the normal full acceleratorposition), the transmission will automaticallyengage kickdown, i.e. immediately shift down to alower gear.
If the accelerator pedal is released from the kick-down position, the transmission will automaticallyshift up again.

Safety function
The transmission control module is equipped witha downshift protection feature to help prevent theengine from overheating.
In some conditions, the transmission will preventdownshifting/kickdown if this would lead to suchhigh engine speed (rpm) that the engine couldbe damaged. If the driver still attempts downshift-ing or kickdown at a high rpm, nothing will hap-pen and the original gear will remain selected.
With kickdown, the vehicle can downshift one ormore steps at a time depending on the enginespeed. The vehicle upshifts when the engine rea-ches its maximum rpm to prevent engine dam-age.

All Wheel Drive (AWD)
All-wheel drive, All Wheel Drive (AWD), alsocalled four-wheel drive, means that power is dis-tributed to all four wheels, which improves trac-tion.
The electric motor that powers the rear wheelsenables electronic all-wheel drive functionality.All-wheel drive reacts differently depending onwhich drive mode is selected.

Drive systems
Volvo Twin Engine combines a combustionengine for the front wheels and an electric motorfor the rear wheels.
Two drive systems
Depending on the selected drive mode andpower available in the electric motor, the drivesystems can either be used separately or in tan-dem.
The electric motor gets its energy from a hybridbattery located under the tunnel console. Thehybrid can be charged from a wall outlet or in aspecial charging station. The combustion enginecan also charge the hybrid battery using a specialhigh-voltage generator.
Both the combustion engine and the electricmotor can generate power directly to the wheels.An advanced control system coordinates both thedrive systems to help optimize driving economy.

If contact occurs, flush the affected areaimmediately with water. Obtain medicalhelp immediately if eyes are affected.
Never expose the battery to open flameor electric spark. Do not smoke near thebattery. Failure to follow the instructionsfor jump starting can lead to injury.

NOTE
The vehicle cannot be started if the hybridbattery is discharged.

Towing using a towline
This section refers to one vehicle being towedbehind another using a towline.
Twin Engine vehicles may not be towed behindanother vehicle due to the risk of damage to theelectric motor. The vehicle must be lifted onto atow truck and transported with all four wheels onthe bed or lifting platform of the truck (no wheelsmay touch the road).
Towing another vehicle
Towing another vehicle requires a lot of power -use the AWD drive mode. This helps charge thehybrid battery and improve the vehicle's drivingand roadholding characteristics.
Before towing another vehicle, check applicablespeed limit regulations.

Jump starting
Do 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 causedamage to the electrical drive motor andthree-way catalytic converter.

WHEELS AND TIRES
542
Tires
The function of the tires is to carry loads, providetraction on road surfaces, reduce vibrations andprotect the wheels from wear.
The tires significantly influence the vehicle's driv-ing characteristics. The type, dimensions, tirepressure and speed rating have a considerableimpact on how the vehicle performs.
Your vehicle is equipped with tires according tothe vehicle's tire information placard on the B-pil-lar (the structural member at the side of the vehi-cle, at the rear of the driver's door opening).

WARNING
A damaged tire could cause the driver to losecontrol of the vehicle.
CAUTION
Some Volvo models are equipped with anUltra High Performance tire and wheel com-bination designed to provide maximum drypavement performance with consideration forhydroplaning resistance. They may be moresusceptible to road hazard damage and,depending on driving conditions, may achievea tread life of less than 30,000 km (20,000miles). Even if this vehicle is equipped withVolvo's advanced AWD or stability system,these tires are not designed for winter driving,and should be replaced with winter tires whenweather conditions dictate.
The tires have good road holding characteristicsand offer good handling on dry and wet surfaces.It should be noted however that the tires havebeen developed to give these features on snow/ice-free surfaces.
Most models are equipped with "all-season" tires,which provide a somewhat higher degree of road-holding on slippery road surfaces than tires with-out the "all-season" rating. However, for optimalroadholding on icy or snow-covered roads, Volvorecommends snow tires on all four wheels.
When replacing tires, be sure that the new tiresare the same size designation, type (radial) andpreferably from the same manufacturer, on all
four wheels. Otherwise there is a risk of alteringthe vehicle's roadholding and handling characte-ristics.

Recommended tires
On delivery, the car is equipped with Volvo origi-
nal tires that have the VOL1 marking on the sideof the tires. These tires have been designed spe-cifically for your vehicle. It is therefore importantwhen replacing tires that the new tires have thissame marking to help maintain the vehicle's driv-ing characteristics, comfort and fuel consumption.

New tires
Tires are perishable goods. After a few years,they will begin to harden and their friction proper-ties will gradually deteriorate. Always replace tireswith the freshest tires possible. This is particularlyimportant for snow tires. A series of numbers is
