WARNING
Orange wiring may only be handled by qualified personnel.
WARNING
A number of electrical components in Twin Engine Plug-in Hybrid vehicles use high-voltage current and can be extremely dan-gerous if handled incorrectly.
Do not touch anything that is not clearly described in this Owner's Man-ual.
Be careful when checking/filling fluidsin the engine compartment.
The layout of the engine compartment may vary depending on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driv- er's side)

Engine oil For the recommended service intervals and warranties to be applied, an approved engineoil must be used.
Volvo recommends:
If the engine oil is not checked regularly and the level becomes low, this could cause seri-ous engine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filled with a specially adapted syntheticengine oil. Great care has been put into thechoice of oil, with consideration given toservice life, startability, fuel consumptionand environmental impact. For the recommended service intervals to apply, an approved engine oil must beused. Only use the prescribed oil grade totop off or change the oil. Otherwise, thereis a risk of the vehicle's service life, starta-bility, fuel consumption and environmentalimpact being affected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Cor-poration disclaims warranty liability forsuch type of damage. Volvo recommends entrusting oil changes to an authorized Volvo workshop.
Volvo uses different systems to warn if the oil level is too low/high or the oil pressure is low.On engine variants with an oil pressure sensor,

a warning symbol is displayed in the instru- ment panel when oil pressure is low
. On
engine variants with an oil level sensor, the
warning symbol in the instrument panel
and display messages are used to alert the driver. Some engine variants have both sys-tems. Contact a Volvo retailer for more infor-mation. Change the engine oil and oil filter according to the schedule specified in the Warranty andMaintenance Records Information booklet.Oils of a higher grade than that specified maybe used. If the vehicle is driven in adverse con-ditions, Volvo recommends using an oil with ahigher grade than that specified.

If this symbol is shown together with a message about low oil level, for example
Engine oil
level low Refill 1 liter, fill only
with the indicated volume, e.g. 1 liter (1 quart).
WARNING
Do not spill oil on the hot exhaust pipes as this could cause a fire.
Viewing oil level in the center displayThe oil level can be viewed using the elec- tronic oil level gauge in the center display oncethe vehicle has been started. The oil levelshould be checked regularly.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heattransferred from the engine to the coolantcan be used to warm the passenger compart-ment.
When refilling coolant, follow the instructions on the package. Never fill the cooling systemwith only water. The risk of freezing isincreased with too low or too high amounts ofcoolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than2 liters (about 2 quarts) of coolant has beenadded to the system, there could be some-thing wrong with the cooling system and star-ting the vehicle could damage the engine. Calla tow truck and do not attempt to start theengine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. Ifcoolant must be filled, unscrew the expan-sion tank cap slowly to relieve overpres-sure.

Cleaning the exterior
The vehicle should be washed as soon as it becomes dirty. This makes the vehicle easierto clean because dirt does not attach asstrongly. It also reduces the risk of scratchesand keeps the vehicle looking new. Wash thevehicle in a car wash or garage with an oilseparator and use car washing detergent.

Polishing and waxing
Polish and wax the vehicle when the paint is matte or to provide extra protection. Thevehicle does not need to be polished until it isat least a year old. However, it can be waxedduring the first year. Do not polish or wax thevehicle in direct sunlight. The surface of thevehicle should not be warmer than 45 °C(113 °F).
Wash and dry the vehicle very carefully before polishing or waxing. Removeasphalt and tar stains with asphaltremover or paint thinner. More stubbornstains can be removed with a grindingpaste designed for vehicle paint.
Use polish first and then liquid or pastewax. Follow the instructions on the pack-age carefully. Many products contain bothpolish and wax.
A wide range of polymer-based waxes canbe purchased today. These waxes are easyto use and produce a long-lasting, high-gloss finish that protects the bodyworkagainst oxidation, road dirt and fading.
