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.

Side impact airbags
As an enhancement to the structural side impact protection built into your vehicle, it is also equip-ped with Side Impact Protection System (SIPS)airbags.
The SIPS airbag system is designed to help increase occupant protection in the event of cer-tain side impact collisions. The SIPS airbags aredesigned to deploy only during certain side-impact collisions, depending on the crashseverity, angle, speed and point of impact.
NOTE
SIPS airbag deployment (one airbag) occurs only on the side of the vehicle affected by theimpact. The airbags are not designed todeploy in all side impact situations.
Components in the SIPS airbag systemThis SIPS airbag system consists of a gas gener- ator, the side airbag modules built into the out-board sides of both front seat backrests, andelectronic sensors/wiring.
WARNING
• The SIPS airbag system is a supplement to the structural Side Impact ProtectionSystem and the three-point seat belt sys-tem. It is not designed to deploy duringcollisions from the front or rear of thevehicle or in rollover situations.
• The use of seat covers on the front seatsmay impede SIPS airbag deployment.
• No objects, accessory equipment or stick-ers may be placed on, attached to orinstalled near the SIPS airbag system orin the area affected by SIPS airbagdeployment.
• Never try to open or repair any compo-nents of the SIPS airbag system. Thisshould be done only by a trained andqualified Volvo service technician.
• In order for the SIPS airbag to provide itsbest protection, both front seat occupantsshould sit in an upright position with theseat belt properly fastened.
• Failure to follow these instructions canresult in injury to the occupants of thevehicle in the event of an accident.

Cross Traffic Alert (CTA)* limitations
CTA functionality may be reduced in certain sit- uations.
LimitationsCTA has limitations in certain situations, for example, the CTA sensors cannot "see" throughother parked vehicles or obstructions. The following are several examples where CTA's "field of vision" may initially be limited andapproaching vehicles cannot be detected untilthey are too close:
The vehicle is pulled far into a parking space
In angled parking spaces, CTA may be "blind" on one side
CTA's blind area
CTA's "field of vision"
However, as you back your vehicle out of a park- ing space, CTA's "field of vision" expands. Examples of other limitations include:
• Dirt, ice or snow obstructing the sensors may reduce the system's function or make itimpossible to detect other vehicles orobjects.
• CTA is deactivated if a trailer's wiring is con-nected to the vehicle's electrical system.
MaintenanceThe CTA sensors are located on the inside of the rear fenders/bumper.
Keep the highlighted area clean (on both sides of the vehicle)
For the system to function optimally, the area over and around the sensors must be kept clean. Do not attach any objects, tape, decals, etc., on the surface of the sensors.
CAUTION
Repairs to the BLIS/CTA systems and/or repainting the rear bumper should only bedone by a trained and qualified Volvo servicetechnician.

357
Driving through standing water
The vehicle should be driven with extreme cau- tion if it is necessary to drive through standingwater.
The vehicle can be driven through water up to a depth approximately level with the floor at walk-ing speed to help prevent water from enteringthe differential and/or the transmission or dam-aging electrical components. • If possible, check the depth of the water before driving through it. Take particular carewhen driving through flowing water.
• Before driving through water, always select the
Off Road drive mode to ensure that the
gasoline engine is running and to maximize ground clearance.
• After driving through water, apply the brakesand check that they are functioning correctly.
• Clean the electrical connections for trailerwiring after driving in mud or water.
• When driving through water, maintain lowspeed and do not stop in the water.
CAUTION
• Damage may occur to the engine, trans- mission, electrical components, etc. if thevehicle is driven through water higherthan its floor level. Be aware that wavescreated by other vehicles could cause thelevel to temporarily be above the vehicle'sfloor level.
• Damage to any components due to waterabove the floor level, vapor lock or insuffi-cient oil is not covered under warranty.
• If the engine has been stopped while thevehicle is in water, do not attempt torestart it. Have the vehicle towed out ofthe water and inspected by a trained andqualified Volvo service technician.
WARNING
• Avoid driving through standing or rushing water. Doing so can be dangerous and itmay also be difficult to determine theactual depth of the water.
• If water cannot be avoided, after drivingthrough the water, press lightly on thebrake pedal to ensure that the brakes arefunctioning normally. Water or mud canmake the brake linings slippery, resultingin delayed braking effect.
