Available drive modes
HYBRID
This is the default mode. The vehicle normally starts in
Hybrid mode 4
. The
engine management system uses both the elec- tric motor and gasoline engine (separately or intandem) and calculates the optimal levels of per-formance, fuel consumption and comfort. Athigher speeds, ground clearance is reducedautomatically to help reduce wind resistance. The amount of driving done using only the elec- tric motor in
Hybrid mode is determined by the
hybrid battery's charge level and the need for heating/cooling in the passenger compartment. If sufficient electrical energy is available, only the electric motor will be activated when the driverpresses the accelerator pedal up to a certainlevel. Above this level, the gasoline engine willstart.The instrument panel gauge when both the electric motor and gasoline engine are being used
The long needle in the gauge indicates the amount of energy that the vehicle is currentlyusing. The short white line between the "light-ning" and "oil drop" symbols indicates theamount of energy available. See also the article"General information about the XC90 T8 TwinEngine Plug-in Hybrid" for additional information. The gasoline engine starts when the response required when the driver presses the acceleratorpedal cannot be provided by the electric motoralone. The gauge also indicates when the battery is being recharged (regenerated) during light brak-ing. See the article "Brakes" for additional infor-mation. When the hybrid battery's charge level is low, thegasoline engine will start more often to help con-serve electrical energy. Charge the battery withthe charging cable as soon as possible or switch to the
Save drive mode.
PURE
This mode activates the electric motor only with as low energy consumption as possible and thelowest possible carbon dioxide emissions. Ground clearance will be lowered to help reduce wind resistance and certain climate system func-tions will be reduced.
Pure mode is available when the hybrid battery is
sufficiently charged. If the level gets too low, the gasoline engine will start. The gasoline engine will also start: • If the vehicle's speed goes above approx. 75 mph (125 km/h)
• If the driver wants more response than theelectric motor alone can provide
• If factors such as cold weather, etc., affectthe system or components
To restart the climate system functions that have been reduced in the mode, press the,
AUTO or
defroster buttons.
4 Unless the vehicle was switched off in Off Road mode. If so, it will restart in Off Road mode.

SAVE
This mode makes it possible to save electrical energy (hybrid battery charge) for times whenusing the electric motor is more suitable (e.g., citydriving). Using the electric motor only saves more fuel at low speeds than at high ones. Therefore, use theSAVE mode primarily when the hybrid battery'scharge level is high and driving will initially be athighway speeds but will end with city drivingwhen electric driving is preferable. If the hybrid battery's charge level is low when this mode is selected, the gasoline engine willstart and charge the hybrid battery up to approx.33%. If the battery's charge level is already above33%, this level will be maintained by the enginemanagement system, which will start/stop the gasoline engine in the same way as in
Hybriddrive mode. This mode increases fuel consumption because the gasoline engine is used to conserve batterycharge for later use.
OFF ROAD
This mode helps maximize the vehicle's capacity to traverse difficult terrain or poor roads. In OFF ROAD, ground clearance is maximized, the steering is light, All Wheel Drive and HillDescent Control are activated and a compassand altimeter will be displayed in the instrumentpanel.This drive mode can only be activated at lowspeeds (the permissible speed range will beshown on the speedometer). At higher speeds,OFF ROAD mode will be cancelled and AWD willbe activated. This mode is not intended for normal street driv- ing.
CAUTION
OFF ROAD drive mode may not be used if the vehicle is towing a trailer without an elec-trical connection. This could result in damageto the pneumatic suspension system's bel-lows.
Due to the increased ground clearance, if the OFF ROAD mode was selected when the enginewas switched off, it will also restart in this mode.
AWD
This mode offers improved traction using four- wheel drive and is intended primarily for low-speed driving on slippery surfaces. However, italso helps increase directional stability at higherspeeds. In this mode, both the electric motor and the gas- oline engine are used continuously, which resultsin higher fuel consumption.
POWER
Power mode is intended for sportier, more active
driving. This mode maximizes the combined effects of the electric motor and the gasoline engine andprovides power to all four wheels. Response topressure on the accelerator pedal is more imme-diate and the transmission shifts up at higherspeeds. Steering response is also more immedi-ate, the suspension is stiffer and lower groundclearance reduces body roll when cornering. In this mode, both the electric motor and the gas- oline engine are used continuously, which resultsin higher fuel consumption.

Brake – B
B can be selected at any time during a drive. In
this mode, the engine braking function is acti- vated when the accelerator pedal is released,which helps charge the hybrid battery. Thismeans that the hybrid battery is charged even ifthe brake pedal is not depressed.
B mode in the instrument panel
With B selected, manual shifting to lower gears
is possible. The gear indicator in the instrument panel shows the gear currently being used (1–8). Each time the gear selector is pulled rearward, the transmission will shift down one gear. In order to manually shift to higher gears, the vehicle must be equipped with steering wheel paddles *.
• Press the gear selector forward to return to D
mode. For smooth shifting and engine performance, the transmission will shift down automatically if thevehicle's speed becomes too low for the selectedgear.
Safety functionTo help avoid excessive rpm that might causeengine damage, the transmission control modulehas a down-shift protection feature that in somesituations may prevent a down-shift or kickdown. During kickdown, the transmission may shift down one or more gears, depending on theengine's rpm and will shift up again when max.rpm is reached for a specific gear.

Emission inspection readiness
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector can thenread "faults." In some states, this type of inspec-tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection for any of the following reasons.
• If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
• If your vehicle's Check Engine light was lit,but went out without any action on your part,OBD II will still have a recorded fault. Yourvehicle may pass or fail, depending on theinspection practices in your area.
• If you had recent service that required dis-connecting the battery, OBD II diagnosticinformation may be incomplete and "notready" for inspection. A vehicle that is notready may fail inspection.
How can I prepare for my next
OBD II
emission inspection?
• If your Check Engine (MIL) light is lit – or was lit but went out without service, have yourvehicle diagnosed and, if necessary, servicedby a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service that required disconnecting the battery, a periodof driving is necessary to bring the OBD IIsystem to "ready" for inspection. Two half-hour trips of mixed stop-and-go/highwaydriving are typically needed to allow OBD II toreach readiness. Your Volvo retailer can pro-vide you with more information on planning atrip.
• Maintain your vehicle in accordance with yourvehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervals are described in your vehicle's Warranty andService Records Information booklet. The following points can be carried out between the normally scheduled maintenance services.
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers, headlights, and taillights.
Monthly:
•
Check cold tire pressure in all tires. Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "min" and"max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with a softcloth. •
Visually inspect battery terminals for corro-sion. Corrosion may indicate a loose terminalconnector, or a battery near the end of itsuseful service life. Consult your Volvo retailerfor additional information.
As needed:
Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup ofdirt, and corrosion that can be caused by salt res-idues. Clean leaves and twigs from air intake vents at the base of the windshield, and from other placeswhere they may collect.
