goal. In addition to continuous environmentalrefinement of conventional gasoline-poweredinternal combustion engines, Volvo is activelylooking at advanced technology alternative-fuelvehicles.
When you drive a Volvo, you become our partnerin the work to lessen the vehicle's impact on theenvironment. To reduce your vehicle's environ-mental impact, you can:
Maintain proper air pressure in your tires.Tests have shown decreased fuel economywith improperly inflated tires.
Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
Drive at a constant speed whenever possible.
See a trained and qualified Volvo servicetechnician as soon as possible for inspectionif the check engine (malfunction indicator)light illuminates, or stays on after the vehiclehas started.
Properly dispose of any vehicle-related wastesuch as used motor oil, used batteries, brakepads, etc.
When cleaning your vehicle, please use gen-uine Volvo car care products. All Volvo carcare products are formulated to be environ-mentally friendly.

Twin Engine vehicles
If possible, precondition the vehicle with thecharging cable before driving.
If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reduces thehybrid battery's charge level.
Choose the Pure drive mode to help mini-mize electric power consumption.
In hilly terrain, put the gear selector in modeB to utilize the electric motor's braking func-tion when the accelerator pedal is released.This helps charge the hybrid battery.

HYBRID INFORMATION
408
General information about TwinEngine
Twin Engine vehicles are driven just like anyother vehicle, but certain functions differ from avehicle powered exclusively by gasoline. Theelectric motor powers the vehicle primarily at lowspeeds; the gasoline engine is used at higherspeeds or during more active driving.
The instrument panel displays Twin Engine-spe-cific information - charging information, selecteddrive mode, distance to discharged battery andhybrid battery charge level.
Different drive modes can be selected while driv-ing, e.g. electric power only or, if more power isneeded, a combination of electric and gasolinepower. The vehicle calculates the optimal combi-nation of driveability, driving experience, environ-mental impact and fuel economy for the selecteddrive mode.
In order to function optimally, the hybrid battery(and its electrical drive systems) and the gasolineengine (and its drive systems) must be at thecorrect operating temperature. Battery capacitycan be considerably reduced if the battery is toocold or too hot. Preconditioning prepares thevehicle's drive systems and passenger compart-ment before driving to help reduce both wear andenergy consumption. It also helps increase thehybrid battery's range.
The hybrid battery which powers the electricmotor is recharged using the charging cable. It
can also be recharged during light braking andthrough engine braking in gear position B. Thecombustion engine can also help recharge thehybrid battery.

Important
No electrical current
Keep in mind that if there is no electrical currentto the vehicle, i.e. the ignition is switched off orthe start battery is discharged, certain functionssuch as brakes, power steering, etc. will not work.

WARNING
If the vehicle does not have electrical currentand both the electric motor and the gasolineengine are switched off, the brakes cannot beused to stop the vehicle.

Towing not permitted
Never tow a Twin Engine vehicle behind anothervehicle, as this could damage the electric motor.

Exterior engine noise
WARNING
Please be aware that there is no sound fromthe 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 TwinEngine Plug-in Hybrid vehicles use high-volt-age current and can be extremely dangerousif handled incorrectly. These components andany orange wiring in the vehicle may only behandled by trained and qualified Volvo servicetechnicians.
Do not touch anything that is not clearly descri-bed in this Owner's Manual.
