06 Starting and driving
Front/rear park assist (accessory/option)
06``147
G020294
Front/rear park assistThe park assist system is designed to assist
you when driving into parking spaces, garages,
etc. It utilizes four ultrasound sensors located
in one or both bumpers to measure the dis-
tance to a vehicle, object, or a person who may
be close to the front or rear of your vehicle.
Park assist is available in two versions:•
Rear bumper only
•
Front and rear bumpers
WARNING
Park Assist is an information system, NOT a
safety system. This system is designed to
be a supplementary aid when parking the
vehicle. It is not, however, intended to
replace the driver's attention and judge-
ment.FunctionThe system is activated automatically when the
vehicle is started. The indicator light in the but-
ton in the center console illuminates.•
The front park assist system is active from
the time the engine is started until the vehi-
cle exceeds a speed of approximately
10 mph (15 km/h). It is also active when the
vehicle is backing up.
•
Rear park assist is active when the engine
is running and reverse gear has been
selected.
Rear park assistThe distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The signal comes
from the rear speakers.
The system must be deactivated when towing
a trailer, carrying bicycles in a rear-mounted
carrier, etc, which could trigger the rear park
assist system's sensors.
NOTE
Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.Front park assistThe distance monitored in front of the vehicle
is approximately 2.5 ft (0.8 m). The audible sig-
nal comes from the audio system's front
speakers.•
It may not be possible to combine auxiliary
headlights and front park assist since
these lights could trigger the system's sen-
sors.
Activating/deactivating park assistThe system is activated automatically when the
vehicle is started.•
Press the Park assist button on the center
console (see page 60) to temporarily deac-
tivate the system(s). The indicator light in
the button will go out when the system has
been deactivated.
•
Park assist will be automatically reactiva-
ted the next time the engine is started, or if
the button is pressed (the indicator light in
the button will illuminate).

06 Starting and drivingFront/rear park assist (accessory/option)
06148
NOTE
•
Front park assist is disengaged auto-
matically when the parking brake is
applied.
•
If the vehicle is equipped with front and
rear park assist, both systems will be
deactivated by pressing the button.
Audible signals from the park assist
systemThe Park Assist system uses an intermittent
tone that pulses faster as you come close to an
object, and becomes constant when you are
within approximately 1 ft (30 cm) of an object
in front of or behind the vehicle. If the volume
of another source from the audio system is
high, this will be automatically lowered.
If there are objects within this distance both
behind and in front of the vehicle, the signal
alternates between front and rear speakers.
Faults in the system
If the yellow warning symbol illu-
minates and
PARK ASSIST
SERVICE REQUIRED
is shown
on the information display, this
indicates that the system is not
functioning properly and has been disengaged.
Consult a trained and qualified Volvo service
technician.
CAUTION
In certain circumstances, the park assist
system may give unexpected warning sig-
nals that can be caused by external sound
sources that use the same ultrasound fre-
quencies as the system. This may include
such things as the horns of other vehicles,
wet tires on asphalt, pneumatic brakes,
motorcycle exhaust pipes, etc. This does
not indicate a fault in the system.
Cleaning the sensors
G026946
Park assist sensorsThe sensors must be cleaned regularly to
ensure that they work properly. Clean them
with water and a suitable car washing deter-
gent.
Ice and snow covering the sensors may cause
incorrect warning signals.
NOTE
If the sensors are obstructed by e.g., dirt,
snow, or ice, this could result in false warn-
ing signals from the park assist system.

07 Wheels and tiresTire Pressure Monitoring System (TPMS) – U.S. models only
07190
The tire pressure monitoring system uses sen-
sors mounted in the tire valves to check infla-
tion pressure levels. When the vehicle is
moving at a speed of approximately 20 mph
(30 km/h) or faster, these sensors transmit
inflation pressure data to a receiver located in
the vehicle.USA – FCC ID: MRXG403MA4
A
This device complies with part 15 of the FCC
rules. Operation is subject to the following
conditions: (1) This device may not cause
harmful interference, and (2) this device
must accept any interference received,
including interference that may cause unde-
sired operation.
When low inflation pressure is detected,
TPMS will light up the tire pressure warning
light (also referred to as a telltale) in the
instrument panel (see page 57), and will dis-
play a message in the text window. The
wording of this message is determined by
the degree of inflation pressure loss.AOn certain models, the FCC code is MRXTG315AM04
NOTE
If a fault occurs in TPMS, the tire pressure
warning light will flash for approximately
1 minute and
TIRE PRESS SYST
SERVICE REQUIRED
will be displayed.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly.

NOTE
TPMS indicates low tire pressure but does
not replace normal tire maintenance. For
information on correct tire pressure, please
refer to the tables on pages 170 and 171, or
consult your Volvo retailer.Erasing warning messagesWhen a low tire pressure warning message has
been displayed, and the tire pressure warning
light has come on:•
Use a tire pressure gauge to check the
inflation pressure of all four tires.
•
Re-inflate the tire(s) to the correct pressure
(consult the tire pressure placard or the
table see page 170).
•
Drive the vehicle for several minutes at a
speed of 20 mph (30 km/h) or faster.
This will erase the warning text and the warning
light will go out.WARNING
Incorrect inflation pressure could lead to tire
failure, resulting in a loss of control of the
vehicle.
Changing wheels with TPMSPlease note the following when changing or
replacing the factory installed TPMS wheels/
tires on the vehicle:•
Only the factory-mounted wheels are
equipped with TPMS sensors in the valves.
•
If the vehicle is equipped with a temporary
spare tire, this tire does not have a TPMS
sensor.
•
If wheels without TPMS sensors are moun-
ted on the vehicle,
TIRE PRESS SYST
SERVICE REQUIRED
will be displayed
each time the vehicle is driven above
25 mph (40 km/h) for 10 minutes or more.
•
Once TPMS sensors are properly installed,
the warning message should not reappear.
•
Volvo recommends that TPMS sensors be
fitted on all wheels used on the vehicle.
Volvo does not recommend moving sen-
sors back and forth between sets of
wheels.NOTE
If a tire is changed or if the TPMS sensor is
moved to another wheel, the sensor’s seal,
nut and valve core should be replaced.
CAUTION
When inflating tires with TPMS valves, press
the pump's mouthpiece straight onto the
valve to help avoid bending or otherwise
damaging the valve.

09 Maintenance and servicing
Engine oil
09``209
NOTE
Volvo uses different systems to indicate a
low oil level or pressure. Some models have
an oil pressure sensor, in which case a
warning symbol (see page 56) is used to
indicate low oil pressure. Other models have
an oil level sensor, in which case the driver
is alerted by the warning symbol in the cen-
ter of the instrument panel and a text in the
information display. Some models use both
systems. Contact a trained and qualified
Volvo service technician for more informa-
tion.Changing engine oil and oil filterSee page 208 for oil specifications and page
268 for oil volumes. Refer to the Warranty and
Service Records Information booklet for infor-
mation on the oil change intervals.
NOTE
Volvo does not recommend the use of oil
additives.
Synthetic oil is not used when the oil is
changed at the normal maintenance inter-
vals except at owner request and at addi-
tional charge. Please consult a trained and
qualified Volvo service technician.
Checking and adding oil
G030880
Location of dipstick (1) and oil filler cap (2)The oil level should be checked every time the
vehicle is refueled. This is especially important
during the period up to the first scheduled
maintenance service.•
The vehicle should be parked on a level
surface when the oil is checked.
•
If the engine is warm, wait for at least
10-15 minutes after the engine has been
switched off before checking the oil.
Checking the oil•
Pull out the dipstick and wipe it with a lint-
free rag.
•
Reinsert the dipstick, pull it out, and check
the oil level.
•
Add oil if necessary. If the level is close to
theMIN mark, add approximately
1 US quart (1 liter) of oil.
•
Run the engine until it reaches normal
operating temperature.
•
Switch off the engine and wait for at least
10-15 minutes and recheck the oil level. If
necessary, add oil until the level is near the
mark.
•
Oil level should be between the MIN and
MAX marks on the dipstick.
