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.

Factors the driver can control
The driver should be aware that the following fac-tors help conserve energy and improve drivingrange:
charging the battery regularly
preconditioning
Pure drive mode
climate control settings
speed and acceleration
the Hold function
tires and tire pressure.
The following table shows the approximate rela-tionship between constant speed and drivingrange. Driving at a lower constant speed helpsincrease the electric motor's driving range.
Constant speed
100 km/h (62 mph) 50 %
80 km/h (50 mph)70 %
60 km/h (37 mph) 90 %
50 km/h (31 mph) 100 %

NOTE
The figures shown in the tables pertain toa new vehicle.
None of the figures are absolute and areaffected by e.g. driving style, environmentand other conditions.

"Hold" and "Charge" functions
In certain situations, it can be useful to controlthe hybrid battery's charge level while driving.This is possible with the Hold and Charge func-tions.
Hold and Charge are available in all drivemodes. The functions will switch off if Pure drivemode is activated.

Function buttons for Hold and Charge
The functions can be activated in the center dis-play's Function view.

Hold
Battery level sustained forlater use.
This function retains the chargein the hybrid battery for theelectric motor and saves availa-ble electrical current for use ata later time, such as when driving in an urbanarea or residential neighborhood.
The vehicle will function as in normal hybrid driv-ing with a discharged battery - in addition toreusing energy from e.g. regenerative braking, thecombustion engine will be used more frequentlyto maintain the charge in the battery.

Preparing for a long trip
It is important to have the vehicle's systems andequipment checked carefully before driving longdistances.
Check that:
the engine is running properly and that fuelconsumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning optimally
all lights are working ‒ adjust the headlightheight if the vehicle is carrying a heavy load
tire tread depth and air pressure are at cor-rect levels. Change to snow tires when driv-ing in areas where there is a risk of snowy oricy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Battery drain
The electrical functions in the vehicle drain thebattery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Useignition mode I instead, as this uses less electri-cal current.
Note that certain accessories may also drainpower from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audiosystem.
–Charge the battery by starting the engineand let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

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.
