WARNING
If the warning symbols for both brake fault and ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is nor- mal when this occurs, drive carefully tothe nearest workshop to have thebrake system checked - an authorizedVolvo workshop is recommended.
If the brake fluid has fallen below theMIN
level in the brake fluid reservoir,
the vehicle should not be driven untilthe brake fluid has been filled. The rea-son for the brake fluid loss must bechecked.

Brake Assist System The brake enhancing system, (BAS 3
), helps
increase braking force and can thereby reduce braking distance.
The system monitors the driver's braking hab- its and increases braking force when neces-sary. Braking force can be increased up to thepoint at which the ABS intervenes. The func-tion is deactivated when pressure on the brakepedal is decreased.

Brakes (p. 403)
Braking on wet roads
Prolonged driving in heavy rain without brak- ing may cause braking effect to be slightlydelayed the first time the brakes are applied.
This may also occur after washing the vehicle. It will then be necessary to apply greater pres-sure to the brake pedal. You should thereforemaintain a greater distance to the vehicleahead. Firmly apply the brakes after washing the vehicle or driving on wet roads. This helpswarm up the brake discs, enabling them to drymore quickly and protecting them against cor-rosion. Consider the current traffic situationwhen braking.

Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle if youdetect engine misfire, noticeable loss ofpower or other unusual operating condi-tions, such as engine overheating or back-firing. A properly tuned engine will helpavoid malfunctions that could damage thethree-way catalytic converter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, whichcan come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cata-lytic converter or exhaust system over-heating.
Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehicle maybe illegal and can cause three-way cata-lytic converter or exhaust system over-heating. This includes: altering fuel injec- tion settings or components, alteringemission system components or locationor removing components, and/or repeateduse of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readings are fed into a control module that continuouslymonitors engine functions and controls fuelinjection. The ratio of fuel to air into the engineis continuously adjusted for efficient combus-tion to help reduce harmful emissions.

Overheating of engine and transmission
In certain driving conditions, such as driving in mountainous areas or hot weather, there isa risk of the engine or transmission overheat-ing, especially when carrying heavy loads.
Engine power may be temporarily limited.
Remove any auxiliary lights mounted in front of the grille when driving in hotweather.
If the temperature in the engine's coolingsystem becomes too high, a warning sym-bol will appear in the instrument panel along with the message
Engine
temperature High temperature Stop
safely. Pull over to a safe location and let
the engine idle for a few minutes to cool down.
If the message
Engine temperature
High temperature Turn off engine orEngine coolant Level low, turn off
engine is displayed, stop the vehicle and
turn off the engine.
If the transmission begins to overheat, an alternative gear shifting program will beselected. An integrated protective functionwill also be activated, the warning symbolwill illuminate and the message

STARTING AND DRIVING
44211. Start your vehicle's engine. If the engine
does not start, allow an additional 10 minutes of charging time and then try tostart the engine again.
NOTE
When the engine is started under normal conditions, the vehicle's electrical drivemotor is prioritized – the gasoline engineremains off. This means that after the startknob has been turned clockwise, the elec-tric motor has "started" and the vehicle isready to be driven. Start of the electricmotor is indicated by the indicator lights onthe instrument panel going out and its pre-selected theme illuminating.
CAUTION
Do not touch the connections between the cable and the vehicle during the startattempt. Risk of sparking.
12. Remove the jumper cables in the reverseorder ‒ first the black cables and then the
red cables. Make sure that none of the clamps of the black jumper cables come into contactwith either vehicle's positive (+) jump startterminals or either of the red jumpercable's connected clamps.
WARNING
PROPOSITION 65 WARNING! Battery
posts, terminals, and related accessories contain lead and lead compounds, chemi-cals known to the state of California tocause cancer and reproductive harm. Washhands after handling.
WARNING
Batteries generate hydrogen gas, which is flammable and explosive.
Do not connect the jumper cable toany part of the fuel system or to anymoving parts. Avoid touching hotmanifolds.
Battery fluid contains sulfuric acid. Donot allow battery fluid to contact eyes,skin, fabrics or painted surfaces.
If contact occurs, flush the affectedarea immediately with water. Obtainmedical help immediately if eyes areaffected.
Never expose the battery to open flameor electric spark. Do not smoke nearthe battery. Failure to follow theinstructions for jump starting can leadto injury.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.

MAINTENANCE AND SERVICE
612
Wash using a sponge, car washing deter- gent and plenty of lukewarm water.
Clean the wiper blades with lukewarmsoap solution or car washing detergent.
Dry the vehicle using a clean, soft chamoisor a squeegee. Try not to let drops ofwater dry in strong sunlight. This couldcause water drying stains that may needto be polished out.
In areas with heavy industrial emissions,more frequent washing of the vehicle'sexterior is recommended.
Tar spots from asphalt may remain evenafter washing. Use a tar remover toremove these spots.
WARNING
Always entrust engine washing to a work- shop. If the engine is hot, there is a risk offire.
CAUTION
Dirty headlights do not work as well. Clean them regularly, e.g. when refueling. Do not use corrosive cleaners. Use water and a non-abrasive sponge.
NOTE
Exterior lighting such as headlights and taillights may develop temporary conden-sation on the inside of the lens. This is nor-mal. All exterior lighting is designed toresist this. Condensation is normally ven-ted out of the lamp housing once the lighthas been lit for some period of time.
CAUTION
Make sure that the panoramic roof and sun shade are closed before washingthe vehicle.
Never use abrasive polishing agents onthe panoramic roof.
Never use wax on the rubber sealsaround the panoramic roof.
CAUTION
Remember to remove dirt from the drain holes in the doors and sills after washingthe vehicle.
