Long-term storage of vehicles with
hybrid batteries
To help minimize degradation of the hybrid bat-
tery if the vehicle is not driven for a prolonged
period (longer than 1 month) the hybrid battery
charge level should be kept at approx. 25%
according to the gauge in the instrument panel.
Do as follows:
1. If the hybrid battery charge level is high, drive
the vehicle until the charge level is approxi-
mately 25%. If the charge level is low, charge
the battery until the level reaches approxi-
mately 25%. 2.

If the vehicle is not driven for more than 6
months or the hybrid battery's charge level is
noticeably below the 25% mark, charge the
battery to about 25% to help compensate for
the natural battery discharge that occurs in
long-term storage. Regularly check the
charge level using the gauge in the instru-
ment display.
NOTE Store the vehicle in as cool a location as pos-
sible to minimize battery aging during long-
term storage. In the summer, park the vehicle
indoors or in a shady location, whichever is
cooler.

424 Starting the vehicle
The vehicle can be started using the start knob
in the tunnel console when the remote key is in
the passenger compartment. Start knob in the tunnel console.
WARNING
Before starting:
• Buckle your seat belt.
• Adjust the seat, steering wheel and mir-
rors.
• Make sure you can fully depress the
brake pedal. The remote key is not physically used to start the
ignition because the vehicle is equipped with the
keyless Passive Start system.
To start the vehicle:
1.

The remote key must be inside the vehicle.
For vehicles with Passive Start, the key must
be in the front section of the passenger
compartment. With the optional keyless lock-
ing/unlocking function*, the key can be any-
where in the vehicle.
2. Press and hold down the brake pedal 1
as far
as possible.
3. Turn the start knob clockwise and release. The control will automatically return to the
original position.
WARNING •
Never use more than one inlay mat at a
time on the driver's floor. If any other type
of floor mat is used, remove the original
mat from the driver's seat floor before
driving. All types of mats must be securely
anchored in the attachment points in the
floor. Make sure the floor mat does not
impede the movement of the brake pedal
or accelerator pedal in any way, as this
could be a serious safety hazard.
• Volvo's floor mats are specially manufac-
tured for your vehicle. They must be prop-
erly secured in the attachment points in
the floor to help ensure they cannot slide
and become trapped under the pedals.
The starter motor will crank until the engine
starts or until its overheating protection is trig-
gered.
During normal start conditions, the vehicle's elec-
tric motor will be prioritized and the gasoline
engine will remain off. This means that once the
start knob is turned clockwise, the electric motor
has been "started" and the vehicle is ready to be
driven. The warning and information symbols in
the instrument panel will go out and the selected
theme will be displayed to indicate that the elec-
tric motor is activated. 1
If the vehicle is moving, it is only necessary to turn the start knob cl\
ockwise to start the engine.

• Brake functions (p. 429) Transmission
The transmission is part of the vehicle's driveline
(power transmission) between the engine and
the drive wheels. The function of the transmis-
sion is to change gears depending on speed
and power needs.
The vehicle has an 8-speed automatic transmis-
sion and an electric motor for rear-wheel drive.
The number of gears allows the engine's torque
and power band to be effectively utilized. Two of
the gears are overdrive gears that save fuel when
driving at a constant engine speed. The steering
wheel paddles* can be used to shift up or down
manually. The instrument panel shows the gear
currently in use.
CAUTION Check the operating temperature of the
transmission to help avoid damage to any of
the drive system components. If there is a risk
of overheating, a warning symbol will appear
in the instrument panel and a text message
will be displayed. Follow the recommenda-
tions given.

Gear selector positions for
automatic transmissions
In vehicles with an automatic transmission, the
system selects the optimal gear for the current
driving conditions. The transmission also has a
manual mode.
The instrument panel shows which gear is cur-
rently in use:
P
, R, N, D or B.
For manual shifting, the gear indicator in the
instrument panel displays the gear currently
being used (1-8).
Selecting gearsThe gear selector is a shift-by-wire selector,
where shifting is done electronically instead of
mechanically. This makes shifting easier and the
gear positions more distinct. Select gears by moving the spring-loaded, non-
locking gear selector forward or backward.
Gear selector positions
Park - P
Park is activated using the P button located next
to the gear selector. Select P when the vehicle is parked or when star-
ting the engine. The vehicle must be stationary
when Park is selected.
To move to another gear from Park, the brake
pedal must be depressed and the ignition in
mode II.
When parking – apply the parking brake before
shifting to Park.
WARNING Always apply the parking brake when parking
on an incline. Selecting a gear or putting the
automatic transmission in P may not be suffi-
cient to keep the vehicle stationary in all sit-
uations.
NOTE The gear selector must be in the P position
before the vehicle can be locked and the
alarm set.

||STARTING AND DRIVING
* Option/accessory.
440 Help functions
The system will automatically shift to P:
• if the ignition is switched off while D or R is
selected.
• if the driver unbuckles the seat belt and
opens the driver's door while the vehicle is
running with the gear selector in a gear other
than P.
To park a vehicle with an unbuckled seat belt and
open door – end P mode by shifting to R or D
again.
Reverse - R
Select R when backing up. The vehicle must be
stationary when Reverse is selected.
Neutral - N
No gear is selected and the engine can be
started. Apply the parking brake if the vehicle is
stationary with the gear selector in N.
To move the gear selector from Neutral to
another gear, the brake pedal must be depressed
and the ignition in mode II.
D drive mode
D is the normal driving gear position. The trans-
mission shifts up or down automatically depend-
ing on acceleration and speed. The vehicle must
be stationary when the gear selector is moved
from R to D.
Brake - B
B can be selected at any time during a drive. In B
mode, the engine braking function is activated
when the accelerator pedal is released, which
helps charge the hybrid battery. This offers addi-
tional opportunities to recharge the hybrid bat-
tery, since the battery is charged even when the
brake pedal is not depressed. B mode in the instrument panel.
From B mode, it is possible to manually shift to
lower gears. The currently selected gear (1-8) will
be displayed in the instrument panel.
• Pull the gear selector backward once to shift
down one gear.
• Pull the gear selector backward again to shift
down to lower gears.
To shift manually to a higher gear, the vehicle
must be equipped with steering wheel paddles*. •
Push the gear selector forward to return to D
mode.
For smooth shifting and engine performance, the
transmission will shift down automatically if the
vehicle's speed becomes too low for the selected
gear.
