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).

electrical socket mounted near the trailer
hitch.
•
The function is automatically deactivated
when the trailer's wiring is disconnected
from the socket. The vehicle will then
accelerate normally.NOTE
Since this function is activated when a con-
nector is plugged into the electrical socket
near the trailer hitch, it will be activated by
any electrical equipment (e.g. bicycle racks
with lighting, etc) that is plugged in, and will
remain active until the equipment is unplug-
ged from the socket.LevelingIf your vehicle is equipped with automatic lev-
eling, the rear suspension always retains the
correct ride height regardless of the load.•
The system adjusts the rear suspension to
the correct level after the vehicle has been
driven a short distance.
•
When the vehicle is stationary, the rear
suspension lowers, which is normal.

07 Wheels and tires
Tire Sealing System
07``185 Introduction
Certain models are equipped with a tire sealing
system that enables you to temporarily seal a
hole in the tread surface and re-inflate a flat tire,
or to adjust a tire’s inflation pressure.
The system consists of an air compressor, a
container for the sealing compound, wiring to
connect the system to the vehicle’s electrical
system via one of the 12-volt sockets, and a
hose used to connect the system to the tire’s
inflation valve.
The 12-volt sockets are located on the rear side
of the center console (in the rear seat) and in
the cargo area.Accessing the tire sealing systemThe tire sealing system is stowed under the
floor of the cargo area. To access it:
1. Fold up or remove any protective floor cov-
ering or carpet.
2. Open the floor hatch.
3. Lift out the tire sealing system.
NOTE
•
The tire sealing system is only intended
to seal holes on the tire’s tread area, not
the sidewall.
•
Tires with large holes or tears cannot be
repaired with the tire sealing system.WARNING
•
After using the tire sealing system, the
vehicle should not be driven farther than
approximately 120 miles (200 km).
•
Have the tire inspected by a trained and
qualified Volvo service technician as
soon as possible to determine if it can
be permanently repaired or must be
replaced.
•
The vehicle should not be driven faster
than 50 mph (80 km/h) while using a tire
that has been temporarily repaired with
the tire sealing system.
•
After using the tire sealing system, drive
carefully and avoid abrupt steering
maneuvers and sudden stops.
