WARNING
Please be aware that there is no sound from the engine when the vehicle is being poweredby the electric motor and it may be difficult todetect by children, pedestrians, cyclists andanimals. This is especially true at low speeds.
High-voltage electrical current
WARNING
A number of electrical components in the XC90 T8 Twin Engine Plug-in Hybrid usehigh-voltage current and can be extremelydangerous if handled incorrectly. These com-ponents and any orange wiring in the vehiclemay only be handled by trained and qualifiedVolvo service technicians.
Hybrid-unique functions
Drive modes
Different drive modes can be selected while driv- ing, e.g., electric power only or a combination ofelectric and gasoline power. The vehicle calcu-lates the optimal combination of drivability, drivingexperience, environmental impact and fuel econ-omy for the selected drive mode. See also thearticle "Drive modes" for additional information.
Instrument panel
In certain driving situations, hybrid-unique infor- mation may be displayed in the instrument panel,such as: a hybrid battery gauge (current chargelevel), the current drive mode, a symbol that illu-minates when the gasoline engine is being used,a Hybrid Guide and the level of energy regenera-tion.
Preconditioning
In order to function optimally, the hybrid battery (and its related electrical systems) and the gaso-line engine (and its drive systems) should be atthe correct operating temperature. The hybridbattery's capacity is reduced considerably if it istoo cold or hot. Preconditioning prepares thevehicle's drive systems and passenger compart-ment before the vehicle is driven to help reducewear and energy consumption.
Charging the hybrid battery
CAUTION
Never connect the charging cable if there is a risk of thunderstorms/lightning.
The XC90 T8 Twin Engine Plug-in Hybrid uses a lithium-ion battery that can be charged in severalways:
• A charging cable can be connected from the vehicle to a 110-volt AC socket. Chargingtime depends on the strength of the current.
• When the brakes are applied lightly, the elec-tric motor is used for engine braking, duringwhich the vehicle's kinetic energy is conver-ted into electric current that is used to helprecharge the hybrid battery.
• The hybrid battery is also recharged to a cer-tain extent when the gasoline engine is inoperation.

General safety information The vehicle is equipped with a number of safety systems for the driver and passengers.
In the event of an accident, there are a number of sensors in the vehicle that react and triggersafety systems such as Roll Stability Control, air-bags, seat belt pretensioners, etc., depending onthe severity of the collision. There are alsomechanical systems such as the WhiplashProtection System.
Warning symbol in the instrument panelThe warning symbol in the instrumentpanel illuminates when the ignition is in mode II or higher. It will go out after
approx. 6 seconds if no faults are
detected in the airbag system.
WARNING
• If the SRS warning light stays on after the engine has started or if it illuminateswhile you are driving, have the vehicleinspected by a trained and qualified Volvoservice technician as soon as possible.
• Never try to repair any component or partof the SRS yourself. Any interference inthe system could cause malfunction andserious injury. All work on these systemsshould be performed by a trained andqualified Volvo service technician. If the dedicated warning symbol is not functioning, the general warning sym-bol will illuminate instead and the samemessage will be displayed in the instru-
ment panel.

Whiplash protection system
The Whiplash protection system (WHIPS) con- sists of specially designed hinges and bracketson the front seat backrests designed to helpabsorb some of the energy generated in a colli-sion from the rear (when the vehicle is rear-ended).
FunctionIn the event of certain rear-end collisions, the hinges and brackets of the front seat backrestsare designed to change position slightly to allowthe backrest/head restraint to help support theoccupant's head before moving slightly rearward.This movement helps absorb some of the forcesthat could result in whiplash.
WARNING
• The WHIPS system is designed to sup- plement the other safety systems in yourvehicle. For this system to function prop-erly, the three-point seat belt must beworn. Please be aware that no systemcan prevent all possible injuries that mayoccur in an accident.
• The WHIPS system is designed to func-tion in certain collisions from the rear,depending on the crash severity, angleand speed.
WARNING
•
Occupants in the front seats must never sit out of position. The occupant's backmust be as upright as comfort allows andbe against the seat back with the seatbelt properly fastened.
• If your vehicle has been involved in a rear-end collision, the front seat backrestsmust be inspected by a trained and quali-fied Volvo service technician, even if theseats appear to be undamaged. Certaincomponents in the WHIPS system mayneed to be replaced.
• Do not attempt to service any componentin the WHIPS system yourself.
WARNING
•Boxes, suitcases, etc. wedged behind the front seats could impede the function ofthe WHIPS system.
• If the rear seat backrests are foldeddown, cargo must be secured to preventit from sliding forward against the frontseat backrests in the event of a collisionfrom the rear. This could interfere withthe action of the WHIPS system.

Do not place any objects behind the front seats that could impede the WHIPS function
WARNING
Any contact between the front seat backrests and the folded rear seat or a rear-facing childseat could impede the function of the WHIPSsystem. If the rear seat is folded down, theoccupied front seats must be adjusted for-ward so that they do not touch the folded rearseat.

Seat belts
Seat belts should always be worn by all occu- pants of your vehicle. Children should be prop-erly restrained, using an infant, car, or boosterseat determined by age, weight and height.
Most states and provinces make it mandatory for occupants of a vehicle to use seat belts.
Reversible seat belt pretensionersReversible seat belt pretensioners is a system inthe front seats that pulls the seat belts slightlytaut prior to a collision. This function helps posi-tion the front seat occupants to help improve theeffects of other safety systems, e.g., the airbagsystem.
Seat belt maintenanceCheck periodically that the seat belts are in goodcondition. Use water and a mild detergent forcleaning. Check seat belt mechanism function asfollows: attach the seat belt and pull rapidly onthe strap.
WARNING
• Never repair the belt yourself; have this work done by a trained and qualifiedVolvo service technician only.
• Any device used to induce slack into theshoulder belt portion of the three-pointbelt system will have a detrimental effecton the amount of protection available toyou in the event of a collision.
• The seat back should not be tilted too farback. The shoulder belt must be taut inorder to function properly.
• Do not use child safety seats or childbooster cushions/backrests in the frontpassenger's seat. We also recommendthat children who have outgrown thesedevices sit in the rear seat with the seatbelt properly fastened.
