Heater
The heater helps the engine and passenger
compartment reach the correct temperature
before and while driving.
The heater has two sub-functions: Parking heater - heats the passenger com-
partment as needed when the parking cli-
mate's preconditioning is activated.
Auxiliary heater - heats the passenger com-
partment and engine while driving.
The heater is a high-voltage coolant heater and is
mounted in the front right-side wheel housing.
Battery and chargingThe heater is powered by the vehicle's hybrid bat-
tery. If the charge level in the hybrid battery is too
low, the heater will switch off automatically and a
message will be displayed in the instrument
panel.
NOTE Make sure that the battery has sufficient
charge if the heater must be used.

Climate (p. 204) Parking heater
The parking heater heats the passenger com-
partment as needed before driving if precondi-
tioning is activated.
The parking heater is one of two sub-functions of
the vehicle's heater. The heater is mounted in the
front right-side wheel housing.
The parking heater starts automatically if the
parking climate's preconditioning is activated and
the passenger compartment needs to be heated.
It switches off automatically when a set timer
time or the heater's maximum run time expires, or
if the car is restarted.
The heater's maximum running time is 40
minutes. Additional heater
The auxiliary heater helps heat the passenger
compartment and engine while driving.
The auxiliary heater is one of two sub-functions
of the vehicle's heater. The heater is mounted in
the front right-side wheel housing.
The auxiliary heater is started and controlled
automatically when extra heat is required while
the vehicle is being driven.
It switches off automatically when the ignition is
switched off.

Tap Settings in the Top view in the center
display.
2. Tap Climate.
3. Select Additional Heater to activate/deac-
tivate automatic start for the auxiliary heater.
NOTE If automatic start of the auxiliary heater is
deactivated, this may impair comfort in the
passenger compartment since the climate
system then does not have a heat source dur-
ing electrical operation.

336Recommended maintenance for the
radar sensor
In order for the camera/radar sensor to function
properly, the area of the windshield in front of the
unit must be kept free of dirt, ice, snow, etc. and
should be washed regularly with water and car
washing detergent.
NOTE
Dirt, ice and snow covering the camera and
radar unit reduce their function and can make
measurement impossible.
It could cause functions to be reduced, deac-
tivated completely or produce an incorrect
function response.

City 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 73
) 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.

Park Assist front, rear and sides
Park Assist has different parameters depending
on which part of the vehicle is approaching an
obstacle.
Front camera Continuous tone warning signal when the obstacle is
less than approx. 30 cm (1 ft) from the vehicle
112
.
Park Assist's front sensors are automatically acti-
vated when the engine is started. They are active
at speeds below 10 km/h (6 mph).
The distance monitored extends approx. 80 cm
(2.5 ft) in front of the vehicle.
NOTE The Parking Assist system is deactivated
when the parking brake is applied or when P
is selected on vehicles with automatic trans-
mission.
CAUTION
When installing auxiliary lights: Make sure
these do not obscure the sensors – the auxili-
ary lights could be perceived as an obstacle.
Back
Continuous tone warning signal when the obstacle is
less than approx. 30 cm (1 ft) from the vehicle
112The rear sensors will be activated if the vehicle
begins rolling backward or if reverse gear is
engaged.
The distance monitored extends
approx. 1.5 meters (5 ft) behind the vehicle.
The Parking Assist system's rear sensors will be
automatically deactivated if the vehicle is backing
up with a trailer connected to the vehicle's elec-
trical system.
NOTE
When reversing with e.g. a trailer or bike car-
rier on the trailer hitch – without Volvo original
trailer cables – the Parking Assist system may
have to be turned off manually to prevent the
sensors from reacting to these.

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.

Emission controls
Three-way catalytic converter

Keep your engine properly tuned. Certain
engine malfunctions, particularly involving the
electrical, fuel or distributor ignition systems,
may cause unusually high three-way catalytic
converter temperatures. Do not continue to
operate your vehicle if you detect engine
misfire, noticeable loss of power or other
unusual operating conditions, such as engine
overheating or backfiring. A properly tuned
engine will help avoid malfunctions that
could damage the three-way catalytic con-
verter.
Do not park your vehicle over combustible
materials, such as grass or leaves, which can
come into contact with the hot exhaust sys-
tem and cause such materials to ignite under
certain wind and weather conditions.
Excessive starter cranking (in excess of one
minute), or an intermittently firing or flooded
engine can cause three-way catalytic con-
verter or exhaust system overheating.
Remember that tampering or unauthorized
modifications to the engine, the Engine Con-
trol Module, or the vehicle may be illegal and
can cause three-way catalytic converter or
exhaust system overheating. This includes:
altering fuel injection settings or compo-
nents, altering emission system components or location or removing components, and/or
repeated use of leaded fuel.NOTE Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen
content of the exhaust gases. Readings are fed
into a control module that continuously monitors
engine functions and controls fuel injection. The
ratio of fuel to air into the engine is continuously
adjusted for efficient combustion to help reduce
harmful emissions.

Fuel (p. 476) Overheating of engine and
transmission
In demanding driving conditions, such as driving
in mountainous areas or hot weather, there is a
risk of the engine or transmission overheating,
especially when carrying heavy loads.
Engine power may be temporarily limited.
Remove any auxiliary lights mounted in front
of the grille when driving in hot weather.
If the temperature in the engine's cooling
system becomes too high, a warning symbol
will appear in the instrument panel along with
the message Engine temperature High
temperature Stop safely. Pull over to a safe location and let the engine idle for a few
minutes to cool down.
If the message

coolant Level low, turn off engine is dis- played, stop the vehicle and turn off the
engine.
If the transmission begins to overheat, an
alternative gear shifting program will be
selected. An integrated protective function
will also be activated, the warning symbol will
illuminate and the message Transmission
