Using the electric or combustion
engine
An advanced control system determines the dis-tance that the vehicle can be driven on the com-bustion engine, electric motor, or both at thesame time.
Its primary function is to use the motor/engineand the current available in the hybrid battery asefficiently as possible based on the characteris-tics of the various drive modes and the poweroutput requested by the driver by pressing theaccelerator pedal.
In certain cases, temporary limitations in the sys-tem or mandatory functions to help maintain alow overall emissions level may result in greateruse of the combustion engine.

Changing drive mode
Select the drive mode that is best suited to thecurrent driving conditions.
The drive mode is changed using the control inthe tunnel console.
Keep in mind that not all drive modes are availa-ble in all situations.
To change drive mode:
1.Press the DRIVE MODE control.
> A pop-up menu will appear in the centerdisplay.
2.Roll the wheel upward or downward to thedesired drive mode.

STARTING AND DRIVING
* Option/accessory.454

Driving
Choose the Pure drive mode to help mini-mize electric power consumption.
Maintain a steady speed and a generous fol-lowing distance to traffic ahead to minimizebraking. This drive mode has the lowestpower consumption.
Balance energy requirements using theaccelerator pedal. Use the indicator on theinstrument panel to see available electricpower and avoid starting the combustionengine unnecessarily. The electric motor ismore effective than the combustion engine,especially at low speeds.
When braking is necessary, brake gentlyusing the brake pedal. This will help rechargethe hybrid battery. A regenerative function isintegrated in the brake pedal and can beaugmented by the electric motor's brakingcapacity when the gear selector is in modeB.
Higher speeds increase energy consumption- air resistance increases with speed.
Activate the Hold function in the Functionview at high speeds when traveling fartherthan is possible using the hybrid battery'scapacity.
Whenever possible, avoid using the Chargefunction to charge the hybrid battery. Charg-ing the battery using the combustion engine
increases fuel consumption and carbon diox-ide emissions.
In a cold climate, reduce heating of the wind-shield/rear window, mirrors, seats and thesteering wheel.
Maintain the correct pressure in the tires andcheck pressure regularly.
The type of tires used could affect energyconsumption - consult a retailer for advice onsuitable tires.
Remove unnecessary items from the vehicle- the heavier the load, the higher the fuelconsumption.
Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
Do not keep the vehicle still on an upwardgradient by using the accelerator pedal. Usethe brakes instead.

Using the electric motor only
When using the electric motor, Volvo TwinEngine provides a combination of good fueleconomy, low emissions and high performance.
For energy-efficient driving:
Select the Pure drive mode to help maximizedriving range using only the electric motor.
Balance energy requirements using theaccelerator pedal. Use the indicator on theinstrument panel's hybrid gauge to see avail-able electric power and avoid starting thecombustion engine unnecessarily.
When braking is necessary, brake gentlyusing the brake pedal. This will recharge thehybrid battery.
Activate the Hold function in the Functionview at high speeds when traveling fartherthan is possible using the hybrid battery'scapacity.
Reduce current consumption in the passen-ger compartment by reducing e.g. fan speed,electric heating, or air conditioning use.
Also follow the general economical driving adviceregarding speed, tires and load to maximizerange.

If contact occurs, flush the affected areaimmediately with water. Obtain medicalhelp immediately if eyes are affected.
Never expose the battery to open flameor electric spark. Do not smoke near thebattery. Failure to follow the instructionsfor jump starting can lead to injury.

NOTE
The vehicle cannot be started if the hybridbattery is discharged.

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.
