2019 VOLVO XC90 TWIN ENGINE air conditioning

||STARTING AND DRIVING
* Option/accessory.

Preconditioning
Whenever possible, precondition the vehicle
before driving by connecting the charging
cable to an electrical outlet.
Avoid parking the vehicle somewhere where
the interior will become too hot or too cold
while the vehicle is parked. If possible, park
the vehicle in a climate-controlled garage.
During a short drive after passenger com-
partment preconditioning, turn off the pas-
senger compartment fan or the air condition-
ing in a hot climate.
If preconditioning is not possible when it is
cold outside, use seat and steering wheel
heating first. Avoid heating the entire pas-
senger compartment to reduce the amount
of current being taken from the hybrid bat-
tery.
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 minimize
braking. This drive mode has the lowest
power consumption.
Balance energy requirements using the
accelerator pedal. Use the indicator on the
instrument panel to see available electric
power and avoid starting the combustion
engine unnecessarily. The electric motor is more effective than the combustion engine,
especially at low speeds.
When braking is necessary, brake gently
using the brake pedal. This will help recharge
the hybrid battery. A regenerative function is
integrated in the brake pedal and can be
augmented by the electric motor's braking
capacity when the gear selector is in mode
B.
Higher speeds increase energy consumption
- air resistance increases with speed.
Activate the Hold function in the Function
view at high speeds when traveling farther
than is possible using the hybrid battery's
capacity.
Whenever possible, avoid using the Charge
function 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 the
steering wheel.
Maintain the correct pressure in the tires and
check pressure regularly.
The type of tires used could affect energy
consumption - consult a retailer for advice on
suitable tires.
Remove unnecessary items from the vehicle
- the heavier the load, the higher the fuel
consumption.
Roof loads increase air resistance and
increase fuel consumption. Remove roof
boxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
Do not keep the vehicle still on an upward
gradient by using the accelerator pedal. Use
the brakes instead.

STARTING AND DRIVING

Using the electric motor only
When using the electric motor, Volvo Twin
Engine provides a combination of good fuel
economy, low emissions and high performance.
For energy-efficient driving:
Select the Pure drive mode to help maximize
driving range using only the electric motor.
Balance energy requirements using the
accelerator pedal. Use the indicator on the
instrument panel's hybrid gauge to see avail-
able electric power and avoid starting the
combustion engine unnecessarily.
When braking is necessary, brake gently
using the brake pedal. This will recharge the
hybrid battery.
Activate the
Hold function in the Function
view at high speeds when traveling farther
than is possible using the hybrid battery's
capacity.
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 advice
regarding speed, tires and load to maximize
range.

"Hold" and "Charge" functions (p. 471) Factors affecting electric motor
range
A number of factors affect the electric motor's
driving range. The ability to achieve a long driv-
ing range varies according to the outside condi-
tions and to how the vehicle is driven.
The certified value for the distance that can be
driven using the electric motor should not be
considered an expected driving range. The actual
range is dependent on a number of factors.
Factors affecting driving rangeThe driver can influence some factors affecting
driving range, but not all.
The longest range is achieved under very favora-
ble conditions when all factors positively influ-
ence range.

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.
596 Using the electrical outlets
The 12 V outlet can be used for devices
intended for this such as MP3 players, coolers
and cellular phones.
The high-voltage outlet* can be used for devices
intended for this, such as chargers, laptops, etc.
The ignition must be in at least mode I for the
outlets to supply current. The outlets will then be
active as long as there is sufficient charge in the
start battery.
If the engine is turned off and the vehicle is
locked, the outlets will be deactivated. If the
engine is turned off and the vehicle remains
unlocked, the sockets will remain active for up to
7 minutes.
NOTE Bear in mind that using the electrical outlets
when the engine is off could cause the starter
battery to have too low of a charge level,
which could limit other functionality.
Accessories connected to the electrical out-
lets can be activated even when the vehicle
electrical system is off or if preconditioning is
used. For this reason, disconnect plugs when
they are not in use to prevent the starter bat-
tery from becoming discharged.
WARNING
Do not use accessories with large or
heavy plugs – they could damage the out-
let or come loose while you are driving.
Do not use accessories that could cause
disruptions to e.g. the vehicle's radio
receiver or electrical system.
Position the accessory so that there is no
risk of it injuring the driver or passengers
in the event of heavy braking or a colli-
sion.
Pay attention to connected accessories
as they can generate heat that could burn
passengers or the interior.
Using 12 V outlets1. Remove the stopper (tunnel console) or fold
down the cover (trunk/cargo compartment)
over the socket and plug in the device.
2. Unplug the device and put the stopper back in (tunnel console) or fold up the cover
(trunk/cargo compartment) when the socket
is not in use or left unattended.
CAUTION The maximum power is 120 W (10 A) per
outlet.
Using high-voltage outletsThe ignition must be in at least mode I for outlets
to supply current. The outlets will then be active
as long as there is sufficient charge in the start
battery.
1. Slide down the cover over the outlet and plug
in the device.
>
The LED 2
light on the outlet will indicate
its status.
2. The outlet is supplying electrical current when the light is glowing steadily green.
3. Disconnect the device by pulling out the plug (do not pull on the cord).
Pull up the cover when the outlet is not in
use or is left unattended.
CAUTION The maximum power is 150 W.
WARNING
Do not attempt to alter or repair the high-volt-
age outlet on your own. Volvo recommends
contacting an authorized Volvo workshop.
