The tailgate can be set to stop opening at a cer-
tain height, for example if the tailgate needs to
be opened in a garage with a low ceiling.
Setting maximum opening height:
1.
Open the tailgate to the desired opening
height.
NOTE It is not possible to program an opening posi-
tion lower than half-open tailgate.
2.
Press the button on the lower edge of
the tailgate and hold for at least 3 seconds.
>

Two brief audio signals will sound to indi-
cate that the position has been stored.
Resetting to maximum opening position:
– Move the tailgate manually to its highest
possible position and press the button
on the tailgate for at least 3 seconds.
>

Two audio signals will sound to indicate
that the stored position has been erased.
The tailgate can then be opened to its
maximum position.
NOTE •
If the system has been working continu-
ously for a prolonged period of time, it will
be switched off to avoid overload. It can
be used again after approximately
2 minutes.

DRIVER SUPPORT
344City Safety limitations
City Safety functionality may be reduced in cer-
tain situations.
Surroundings
Low objects
Hanging objects, such as flags for overhanging
loads or accessories such as auxiliary lights or
front protective grids that extend beyond the
height of the hood, may limit City Safety function-
ality.
Slippery road conditions
The extended braking distance on slippery roads
may reduce City Safety's capacity to help avoid a
collision. In these types of situations, the Anti-
lock Braking System and Electronic Stability Con-
trol (ESC 77
) will help provide optimal braking
power with maintained stability.
Backlighting
The visual warning signal in the windshield may
be difficult to detect in bright sunlight, if there are
reflections, or if the driver is wearing sunglasses
or not looking straight ahead.
Heat
If the temperature in the passenger compartment
is high due to e.g. bright sunlight, the visual warn-
ing signal in the windshield may be temporarily
disabled.
Camera and radar sensor's field of vision
The camera's field of vision is limited and in cer-
tain situations, it may be unable to detect pedes-
trians, large animals, cyclists or vehicles, or it may
detect them later than expected.
Vehicles that are dirty may be detected later than
clean vehicles, and in dark conditions, motorcy-
cles may be detected late or not at all.
If a text message displayed in the instrument
panel indicates that the camera/radar sensor is
obstructed, it may be difficult for City Safety to
detect pedestrians, large animals, cyclists, vehi-
cles or lane markings in front of the vehicle. City
Safety functionality may therefore be reduced.
Text messages may not be displayed for all situa-
tions in which the windshield sensors are
blocked. The driver must therefore always keep
the windshield in front of the camera/radar sen-
sor clean.
CAUTION Maintenance and replacement of City Safety
components may only be performed by a
workshop – an authorized Volvo workshop is
recommended.
Driver intervention
Backing up
City Safety is temporarily deactivated when the
vehicle is backing up.
Low speed
City Safety is not activated at very low speeds
under 4 km/h (3 mph). The system will therefore
not intervene in situations in which your vehicle is
approaching another vehicle very slowly, such as
when parking.
Active driver
Action by the driver always has priority. City
Safety will therefore not react or will react at a
later stage with a warning or intervention in situa-
tions in which the driver is clearly steering and
operating the accelerator pedal, even if a collision
is unavoidable.
An active and aware driving style may therefore
delay collision warnings and intervention in order
to minimize unnecessary warnings.

Electronic Stability Control

STARTING AND DRIVING
* Option/accessory.
450 Leveling control* and suspension
The vehicle's leveling control system adjusts the
suspension and shock absorbers automatically
to help provide good comfort and control while
driving. Leveling can also be controlled manually
to facilitate loading or getting in and out of the
vehicle.
Pneumatic suspension and shock
absorbers
The system is adapted to the selected drive
mode and vehicle speed. The pneumatic suspen-
sion reduces the vehicle's ground clearance at
higher speeds to reduce air resistance and
increase stability. The shock absorbers are nor-
mally set to provide the best possible comfort and are adjusted continuously according to the
road surface and the vehicle's acceleration, brak-
ing and cornering.
The instrument panel indicates
when the suspension level is
being adjusted. The level cannot be adjusted when any of the
side doors or the tailgate is open.
ParkingWhen parking, make sure that there is adequate
space above and below the vehicle since ground
clearance may vary depending on e.g. ambient
temperature, how the vehicle is loaded, if loading
mode is used, which drive mode is selected after
the engine is started, etc.
The level may also be adjusted a period after the
vehicle is parked. This is to compensate for any
height changes that may occur due to tempera-
ture changes in the air springs when the vehicle
cools.
TransportingWhen transporting the vehicle on a ferry, train or
truck, only secure (lash) the vehicle around the
tires, not using any other parts of the chassis.
Changes in the pneumatic suspension may occur
during transport, which could adversely affect the
lashing and result in damage.

When the vehicle is parked and the
engine is turned off, the level is lowered.
(Level adjustment will stop if a side door
is opened and will resume after a slight
delay when the door has been closed.)
When the engine is started and the vehi-
cle begins to move, the level will be raised
to the height set by the selected drive
mode.
Disable Leveling Control
In certain situations, this function must be turned
off, e.g. before the vehicle is raised using a jack*.
The level difference caused by raising the vehicle
with a jack could cause problems with the pneu-
matic suspension.

• Loading recommendations (p. 586) Low Speed Control
The low-speed function, Low Speed Control
(LSC), facilitates and improves control and trac-
tion on rough roads and slippery surfaces, e.g.
when towing a trailer on grass or up boat ramps.
The function is included in the Off Road drive
mode.
Low Speed Control is designed for driving on
rough roads and when towing trailers at low
speeds, up to approximately 40 km/h (25 mph).
When driving at low speeds, LSC prioritizes low
gears and all-wheel drive to help avoid wheel spin
and improve traction on all wheels. The accelera-
tor pedal will be less responsive to improve trac-
tion and speed control at low speeds.
The function is activated together with Hill
Descent Control (HDC), which makes it possible
to control speed going down steep hills using the
accelerator pedal and reduces the need to use
the brake pedal. The system makes it possible to
maintain a low and uniform speed when driving
down steep hills.

battery.
This function charges the
hybrid battery with the help of
the combustion engine for
increased use of the electric
motor at a later time. This function is not available
if the hybrid battery's charge level is already high.
Symbols in the instrument panel The symbol is displayed in the hybrid battery gauge
when Hold is activated. The symbol is displayed in the hybrid battery gauge
when Charge is activated.

It is important to have the vehicle's systems and
equipment checked carefully before driving long
distances.
Check that:
• the engine is running properly and that fuel
consumption is normal
• there are no leaks (fuel, oil or other fluid)
• the brake pedal is functioning optimally
• all lights are working ‒ adjust the headlight
height 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 or
icy roads.
• the start battery is sufficiently charged
• the wiper blades are in good condition

Tread wear indicator
The tread wear indicator shows the status of the
tire's tread. The tread wear indicator is a narrow elevated
strip running across the tire's longitudinal tread
grooves. The letters TWI (Tread Wear Indicator)
are visible on the side of the tire. When approxi-
mately 1.6 mm (1/16 inch) is left on the tread,
the tread will be at the same height as the tread
wear indicator. Replace the tire as soon as possi-
ble. Tires with low tread offer very poor traction in
rain or snow.

Tires (p. 550) Tire terminology
The following is a glossary of tire-related terms.
The tire suppliers may have additional markings,
notes or warnings such as standard load, radial
tubeless, etc.
• Tire information placard: A placard show-
ing the OE (Original Equipment) tire sizes,
recommended inflation pressure, and the
maximum weight the vehicle can carry.
• Tire Identification Number (TIN): A number
on the sidewall of each tire providing infor-
mation about the tire brand and manufactur-
ing plant, tire size and date of manufacture.
• Inflation pressure: A measure of the
amount of air in a tire.
• Standard load: A class of P-metric or Metric
tires designed to carry a maximum load at 35
psi [37 psi (2.5 bar) for Metric tires]. Increas-
ing the inflation pressure beyond this pres-
sure will not increase the tires load carrying
capability.
• Extra load: A class of P-metric or Metric
tires designed to carry a heavier maximum
load at 41 psi [43 psi (2.9 bar) for Metric
tires]. Increasing the inflation pressure
beyond this pressure will not increase the
tire's load carrying capability.
• kPa: Kilopascal, a metric unit of air pressure.
• PSI: Pounds per square inch, a standard unit
of air pressure. •
B-pillar: The structural member at the side
of the vehicle behind the front door.
• Bead area of the tire: Area of the tire next
to the rim.
• Sidewall of the tire: Area between the bead
area and the tread.
• Tread area of the tire: Area of the perime-
ter of the tire that contacts the road when
mounted on the vehicle.
• Rim: The metal support (wheel) for a tire or a
tire and tube assembly upon which the tire
beads are seated.
• Maximum load rating: a figure indicating
the maximum load in pounds and kilograms
that can be carried by the tire. This rating is
established by the tire manufacturer.
• Maximum permissible inflation pressure:
the greatest amount of air pressure that
should ever be put in the tire. This limit is set
by the tire manufacturer.
• Recommended tire inflation pressure:
inflation pressure, established by Volvo,
which is based on the type of tires that are
mounted on a vehicle at the factory. This
information can be found on the tire inflation
placard(s) located on the driver's side B-pillar
and in the tire inflation table in this chapter.
• Cold tires: The tires are considered to be
cold when they have the same temperature
as the surrounding (ambient) air. This tem-

Tires (p. 550) Tire sidewall designations
The following information can be found on a
tire's sidewall. Federal law mandates that tire manufacturers
place standardized information on the sidewall of
all tires (see the illustration).
The vehicle has been certified with certain combi-
nations of wheels and tires.
The following information is listed on the tire
sidewall:
The tire designation:
NOTE Please be aware that the following tire desig-
nation is an example only and that this par-
ticular tire may not be available on your vehi-
cle.
1.
215: the width of the tire (in millimeters)
from sidewall edge to sidewall edge. The
larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its width
in percent.
3. R: Radial tire (the designation RF and the symbol indicate that the vehicle is
equipped with optional self-supporting run
flat tires 3
.
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example, a
load index of 95 equals a maximum load of
1521 lbs (690 kg).
6. H: The tire's speed rating, or the maximum
speed at which the tire is designed to be
driven for extended periods of time, carrying
a permissible load for the vehicle, and with
correct inflation pressure. For example, H
indicates a speed rating of 210 km/h
(130 mph). 3
Self-supporting run flat tires may not be available on all models.
