STARTING AND DRIVING

Preconditioning
•If possible, precondition the vehicle with the charging cable before driving.
• Avoid parking the vehicle so that the passen-ger compartment becomes too hot or cold.Park, if possible, in a climate controlled park-ing garage.
• For short drives after using the precondition-ing function, turn off the climate systemblower if possible.
• 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.
Driving
•
Choose the Pure drive mode to help mini-
mize electric power consumption.
• Maintain a constant speed and an adequate distance to the vehicle ahead to minimizeuse of the brakes.
• Balance energy requirements using theaccelerator pedal and utilize the gauge onthe instrument panel to see the amount ofpower available from the electric motor. Thishelps avoid starting the gasoline engineunnecessarily. The electric motor is moreenergy-efficient than the gasoline engine,especially at lower speeds. See also the arti-cle "Hybrid-related symbols and messages". •
Brake as gently as possible; doing socharges the hybrid battery. There is a regen-erative function in the brake pedal which canbe augmented by the electric motor's brakingcapacity when the gear selector is in mode B
.
• Higher speeds increase energy consumption and the vehicle's wind resistance increasesalong with speed. Do not exceed postedspeed limits.
• In hilly terrain, put the gear selector in mode B
to utilize the electric motor's braking func-
tion when the accelerator pedal is released. This helps charge the hybrid battery.
• Use the
Hold function at highway speeds
when traveling farther than is possible using the hybrid battery's capacity.
• Whenever possible, avoid using the
Chargefunction to charge the hybrid battery. Charg- ing the battery using the gasoline engineincreases fuel consumption and carbon diox-ide emissions.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold).
• Use tires recommended by Volvo for yourvehicle.
• Remove snow tires when threat of snow orice has ended. •
Note that roof racks, ski racks, etc, increaseair resistance and also energy consumption.
• Avoid driving with open windows.
Handling and roadholding
• Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so thatcapacity weight or maximum permissible axleloads are not exceeded.
• At the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned morethan might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alterwith the vehicle load. The heavier the load inthe cargo compartment, the less the ten-dency to understeer.

Overheating the engine and transmission
In demanding driving conditions, such as when transporting heavy loads, driving in mountainousareas or in very hot weather there is a risk ofoverheating the engine or transmission.
• The engine's output may be slightly limited if there is a risk of overheating.
• Remove e.g., auxiliary lights mounted in frontof the grille in hot weather.
• If the temperature of the engine coolantbecomes too high, the warning symbol will illuminate and the message
Engine
temperature/Stop safely will be displayed.
Stop the vehicle as soon as possible in a safe place and let the engine idle for severalminutes.
• If the message
Engine temperature/High
temperature Turn off engine or Engine
coolant/Stop safely is displayed, stop
safely and turn off the engine.
• If the transmission begins to overheat, an alternative gear shifting program will beselected. An integrated protective functionwill also by activated, the warning symbol will illuminate and the message
Transmission
warmHigh temperature Reduce speed
or Transmission warmStop safely, wait
for cooling will be displayed in the instru-
ment panel. •
The air conditioning may be switched off temporarily.
• After a prolonged period of driving, do notturn off the engine immediately after stop-ping.
• The engine cooling fan commonly continuesto run for several minutes after the enginehas been turned off.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator) maystart or continue to operate (for up to6 minutes) after the engine has beenswitched off.

Hybrid battery: stores electrical current, which is provided by connecting the chargingcable to the electricity grid, through regener-ative braking or from the high-voltage gener-ator. This makes it possible to drive using theelectric motor or to power the electrical airconditioning to precondition the passengercompartment.
Gasoline engine: starts when the charge level in the electric motor is too low to pro-vide the power output that the driver requires.
High voltage generator3
: charges the hybrid
battery and starts the gasoline engine. It can also provide the gasoline engine with extraelectrical current.
Electric motor: powers the vehicle using electricity and can provide extra torque andpower during acceleration. It combines with the gasoline engine to provide all-wheel drivefunctionality and regenerates braking energyinto electrical current.

Hybrid battery charging cable
The charging cable is used to recharge your vehicle's hybrid battery. Only use the cable provi-ded with your vehicle or one purchased from aVolvo retailer.
The charging cable is stowed in a storage compartment under the cargo area floor
WARNING
Only use the charging cable provided with your vehicle or a replacement cable pur-chased from a Volvo retailer.

Automatically connecting to a workshop
Without driver confirmation
This is the most convenient way to transmit trou- ble-shooting data. The driver does not need toconfirm that the vehicle will establish a connec-tion. If the vehicle stops at a workshop and the engine is switched off using the start knob, a messagewill appear above the status bar in the center dis-play. The vehicle will be automatically connectedwhen the driver's door is opened if the driver does not tap the
Cancel button in the message.
To help prevent the driver from being disturbed by unwanted requests to connect (e.g., if thevehicle is often parked near a workshop with anauthorized Volvo network), the vehicle will switchto manual connection if the driver cancels a con-nection request twice within 5 days.
With driver confirmation
With this alternative, the driver must confirm a connection. If the vehicle stops at a workshop and the engine is switched off using the start knob, a pop-upwindow will open in the center display. The vehi-cle will be automatically connected when the driv- er's door is opened if the driver taps
Connect in
the pop-up window. If the driver does nothing or taps the pop-up window's
Abort button, no
attempt will be made to establish a connection.
NOTE
To help prevent the driver from being distur- bed by unwanted requests to connect (e.g., ifthe vehicle is often parked near a workshopwith an authorized Volvo network), the vehiclewill switch to manual connection if the drivercancels a connection request twice within5 days.
Manually connecting to a workshopManual connections are handled by the service technician.
Changing the way a connection is madeThe type of connection (manual or automatic)can be changed in the center display's Settingsmenu.
1. Pull down the center display's Top view and
tap

arrive, Ask before connecting or Never
connect and never ask (manual connec-
tions).

Hybrid battery specifications
The hybrid battery is used to power the electric motor for the rear wheels when the gasolineengine is not being used.
Type: lithium-ion
Power reserve: 9.2 kWh
NOTE
The capacity of the hybrid battery diminishes somewhat with age and use, which couldresult in increased use of the gasoline engineand consequently, slightly higher fuel con-sumption.
