STARTING AND DRIVING
* Option/accessory.
434 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 overheating protection is triggered.
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.

435
In some situations, such as in cold weather or if
the hybrid battery's charge level is too low, the
gasoline engine will start instead.
The vehicle should not be started with the charg-
ing cable connected. However, if the cable can-
not be pulled out or if the vehicle incorrectly
detects a cable that is not connected, the vehicle
can be started using an override procedure:
1.

Press the brake pedal and turn the start
knob clockwise.
2. Charge cable Remove before start will
appear in the instrument panel.
3.

Turn the start knob clockwise again.
4. Removed? Turn and hold start knob 7s
will appear. Turn the knob clockwise and hold
it for 7 seconds to start the vehicle. Location of the backup reader in the tunnel console. If the
Vehicle key not found message is shown
in the instrument panel at start, place the remote
key at the backup reader and then make a new
start attempt.
NOTE When the remote key is placed in the backup
reader, make sure that no other vehicle keys,
metal objects or electronic devices (e.g. cellu-
lar phones, tablets, laptops or chargers) are in
the backup reader. Multiple vehicle keys close
to each other in the backup reader can dis-
rupt their functionality.
If Vehicle start System check, wait is dis-
played in the instrument panel while attempting
to start the vehicle, wait until the message disap-
pears and try again to start the vehicle.
CAUTION If the engine has not responded after 3
attempts – wait for 3 minutes before starting
a new attempt. Starting capability increases if
the starter battery is given time to recover.
NOTE
The vehicle cannot be started if the hybrid
battery is discharged.
WARNING Never remove the remote control key from
the vehicle while driving.
WARNING

Always remove the remote key from the
passenger compartment when you leave
the vehicle and make sure the ignition is
in mode 0.
Always put the gear selector in P and
apply the parking brake before leaving
the vehicle. Never leave the vehicle unsu-
pervised while the engine is running.
Always open the garage door fully and
make sure that ventilation is very good
before starting the engine in a garage.
The exhaust fumes produced by the vehi-
cle contain carbon monoxide, which is
invisible and odorless but very toxic.
NOTE With a cold start, idling speed may be consid-
erably higher than normal for certain engine
types. This is done to get the emissions sys-
tem up to normal operating temperature as
quickly as possible, which minimizes exhaust
emissions and protects the environment.

Ignition modes
The vehicle's ignition can be put in various
modes (levels) to make different functions availa-
ble.
To enable the use of a limited number of func-
tions when the engine is not running, the ignition
can be put in one of three different levels: 0, I
and II. These levels are referred to as "ignition
modes" in the Owner's Manual.
The following table shows which functions are
available in each ignition mode: Mode
Functions
0 The odometer, clock and tem-
perature gauge are illuminated A
.
The power* seats can be
adjusted.
The power windows can be used.

Brakes
The brake pedal is used to apply the vehicle's
regular brakes, which are part of the brake sys-
tem.
The vehicle is equipped with two brake circuits. If
one brake circuit is damaged, the brake pedal will
go down further when depressed. More pressure
will then be required from the driver for normal
braking effect.
WARNING
The power brakes only work when the electric
motor or combustion engine is running.
If the brake pedal is used when the engine is
switched off, greater pressure must be applied to
brake the vehicle.
In very hilly areas or when driving with a heavy
load, gear position B can be used to augment the
brakes with engine braking.
Use the Off Road drive mode to increase the
engine braking effect when driving on steep
downgrades at low speeds.
Anti-lock brakesThe vehicle is equipped with an Anti-lock Braking
System (ABS), which helps prevent the wheels
from locking and helps maintain steering control
when braking. Vibrations may be felt from the brake pedal when ABS is operating, which is nor-
mal.
After the vehicle is started, a brief test of the
ABS system is automatically performed when the
driver releases the brake pedal. An additional
automatic test of the system may be performed
when the vehicle is traveling at a low speed. Dur-
ing the test, the brake pedal may feel as though it
is pulsating.
Light braking charges the hybrid batteryWhen the brakes are applied lightly, the electric
motor braking function is used. This converts the
vehicle's kinetic energy into electrical energy,
which is used to charge the hybrid battery. When
the battery is being charged with the electric
motor braking function, this will be indicated in
the instrument panel.
When the battery is being charged with the electric
motor braking function, this will be indicated in the
instrument panel.
This function is active at speeds in the range of
150-5 km/h (93-3 mph). When braking at
speeds outside of this range, or during harder
braking, the hydraulic braking system is used to
augment braking. This is indicated in the instru-
ment panel with the pointer down in the red area.

and ABS fault are lit simultaneously, there
may be a fault in the brake system.
If the brake fluid reservoir level is normal
when this occurs, drive carefully to the
nearest workshop to have the brake sys-
tem checked - an authorized Volvo work-
shop is recommended.
If the brake fluid has fallen below the MIN
level in the brake fluid reservoir, the vehi-
cle should not be driven until the brake
fluid has been filled. The reason for the
brake fluid loss must be checked.

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.
If the vehicle is pointing uphill: Turn the front wheels so they are pointing
away from the curb.
If the vehicle is pointing downhill:
Turn the front wheels so they are pointing
toward the curb.
Heavy load uphill
Heavy loads, such as a trailer, could cause the
vehicle to roll backward when the parking brake
is released automatically on steep uphill gradi-
ents. To help avoid this, pull the control upward
while you are driving away. Release the control
when the vehicle gains traction.

Parking brake malfunction
If you are unable to deactivate or activate the
parking brake after several attempts, contact an
authorized Volvo workshop.
A audible warning signal will sound if the parking
brake is applied while the vehicle is being driven.
If the vehicle must be parked before the problem
is rectified, turn the wheels as when parking on
an incline and put the gear selector in P.
Low battery charge levelIf the battery charge level is too low, it will not be
possible to apply or release the parking brake.
Connect an auxiliary battery to the vehicle if the
battery is discharged.
Replacing brake padsDue to the design of the electric parking brake,
the rear brake pads must be replaced by a work-
shop. An authorized Volvo workshop is recom-
mended.

When shutting off
If the function is active and holding the
vehicle stationary using the normal
brakes (A symbol lit), the brake pedal
must be depressed while pressing the
button in order to deactivate Auto-hold.
The function will remain off until it is reactiva-
ted.
When Auto-hold is switched off, Hill Start
Assist (HSA) will remain active to help pre-
vent the vehicle from rolling backward when
starting up a hill.
Related information
Auto-hold brakes (p. 446) Hill Start Assist
The function for assisting when starting the vehi-
cle on inclines, Hill Start Assist (HSA), helps
prevent the vehicle from rolling backward when
starting on an uphill gradient. When backing up
a hill, HSA helps prevent the vehicle from rolling
forward.
The function retains pressure from the brake
pedal in the brake system for several seconds
after the brake pedal has been released.
This temporary braking effect is released after a
few seconds or when the driver begins driving.
Hill Start Assist is available even if the Auto-hold
brake function is switched off.

Brakes (p. 439) Braking assist after a collision
In a collision in which the activation level is
reached for the pyrotechnic seat belt tensioners
or airbags, or if a collision with a large animal is
detected, the vehicle's brakes will be automati-
cally activated. This function is intended to help
prevent or reduce the effects of any subsequent
collision.
After a serious collision, it may no longer be pos-
sible to control and steer the vehicle. In order to
avoid or mitigate a possible further collision with
a vehicle or an object in the vehicle's path, the
brake assist system is activated automatically to
help stop the vehicle safely.
The brake lights and hazard warning flashers are
activated during braking. When the vehicle has
stopped, the hazard warning flashers will con-
tinue to flash and the parking brake will be
applied.
If braking is not appropriate, e.g. if there is a risk
of being hit by passing traffic, the driver can over-
ride the system by depressing the accelerator
pedal.
This function assumes that the brake system is
intact after a collision.
Brake assist is part of the Rear Collision Warning
and Blind Spot Information safety systems.
