ECO Climate
In Pure mode, ECO climate is automatically acti-vated in the passenger compartment to helpreduce energy consumption.

NOTE
When the Pure drive mode is activated, set-tings for certain climate system and electricityconsuming functions are reduced. Some ofthese settings can be reset manually, but fullfunctionality will only be restored by leavingPure mode or adapting the Individual drivemode to full climate system functionality.
If condensation forms on the windows, tap themax defroster button, which will function normally.

AWD
Improves the vehicle's traction and handlingby increasing all-wheel drive.
This drive mode locks the vehicle in all-wheeldrive. An optimal distribution between front andrear axle torque helps provide the best possiblecontrol, stability and traction, e.g. on slipperyroads or when towing a heavy trailer or anothervehicle. The AWD drive mode is always availableregardless of the hybrid battery's charge status.
Both the combustion engine and the electricmotor are engaged to enable all-wheel drive,which results in higher fuel consumption.
In the other drive modes, the vehicle automati-cally adapts the need for all-wheel drive accord-ing to the road surface, and can activate the elec-tric motor or start the combustion engine as nee-ded.
POWER
Power mode is designed to provide sportierdriving characteristics and a faster accelera-tion response.
This drive mode maximizes the combined powerfrom the combustion engine and the electricmotor by providing power to both the front andrear wheels. Gear shifting will be faster and moredistinct and the transmission will prioritize gearswith a higher traction force. Steering response isfaster and suspension is stiffer.
Both the combustion engine and the electricmotor are engaged to enable all-wheel drive,which results in higher fuel consumption.
This drive mode is optimized for maximum per-formance and throttle response. It changes thethrottle response, gear shifting program andturbo boost system. Chassis settings and steer-ing and brake response are also optimized. ThePower drive mode is always available regardlessof the hybrid battery's charge status.

INDIVIDUAL
Customizes drive mode to personal preferen-ces.
Select one of the drive modes as a basis andadjust the settings to achieve your preferred driv-ing characteristics. These settings will be storedin your driver profile.
Individual drive mode is only available if it hasbeen activated in the center display.

WARNING
Carbon monoxide is a poisonous, colorless,and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumes insidethe vehicle, make sure the passenger com-partment is ventilated, and immediately returnthe vehicle to a trained and qualified Volvoservice technician for correction.

Demanding driving
In demanding driving conditions, such as whentowing a trailer or driving in hot weather or forprolonged periods at high altitudes, it may be a
good idea to switch to a higher-octane fuel (AKI5
91 or higher) or to switch to another brand ofgasoline in order to fully utilize the vehicle'sengine capacity and optimize traction.

Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certainengine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components
or location or removing components, and/orrepeated use of leaded fuel.

NOTE
Unleaded fuel is required for vehicles withthree-way catalytic converters.

Heated oxygen sensors
The heated oxygen sensors monitor the oxygencontent of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

Towing using a towline
This section refers to one vehicle being towedbehind another using a towline.
Twin Engine vehicles may not be towed behindanother vehicle due to the risk of damage to theelectric motor. The vehicle must be lifted onto atow truck and transported with all four wheels onthe bed or lifting platform of the truck (no wheelsmay touch the road).
Towing another vehicle
Towing another vehicle requires a lot of power -use the AWD drive mode. This helps charge thehybrid battery and improve the vehicle's drivingand roadholding characteristics.
Before towing another vehicle, check applicablespeed limit regulations.

Jump starting
Do not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.

CAUTION
Attempts to tow-start the vehicle could causedamage to the electrical drive motor andthree-way catalytic converter.

Determining the vehicle's permittedweight
Properly loading your vehicle will provide maxi-mum return of vehicle design performance.

Weight designations
Before loading your vehicle, familiarize yourselfwith the following terms for determining yourvehicle's weight ratings, with or without a trailer,from the vehicle's Federal/Canadian Motor Vehi-cle Safety Standards (FMVSS/CMVSS) label, andthe vehicle's tire information placard:

Curb weight
The weight of the vehicle including a full tank offuel and all standard equipment. It does notinclude passengers, cargo, or optional equipment.

Capacity weight
All weight added to the curb weight, includingcargo and optional equipment. When towing, tow-bar weight is also part of cargo weight.

Permissible axle weight
The maximum allowable weight that can be car-ried by a single axle (front or rear). These num-bers are shown on the Federal/Canadian MotorVehicle Safety Standards (FMVSS/CMVSS) label.The total load on each axle must never exceed itsmaximum permissible weight.

Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weightof occupants and cargo should never exceedXXX kg or XXX lbs." on your vehicle's plac-ard.
2. Determine the combined weight of the driverand passengers that will be riding in yourvehicle.
3. Subtract the combined weight of the driverand passengers from XXX kg or XXX lbs.
4. The resulting figure equals the availableamount of cargo and luggage load capacity.For example, if the "XXX" amount equals1400 lbs. and there will be five 150 lb. pas-sengers in your vehicle, the amount of availa-ble cargo and luggage load capacity is 650lbs. (1400 - 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggageand cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculatedin Step 4.
6. If your vehicle will be towing a trailer, loadfrom your trailer will be transferred to yourvehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.

LOADING, STORAGE AND PASSENGER COMPARTMENT
