General information
G032949
Location of the side impact (SIPS) airbags (front
seats only)
As an enhancement to the structural side
impact protection built into your vehicle, it is
also equipped with Side Impact Protection
System (SIPS) airbags.
The SIPS airbag system is designed to help
increase occupant protection in the event of
certain side impact collisions. The SIPS air-
bags are designed to deploy only during cer-
tain side-impact collisions, depending on the
crash severity, angle, speed and point of
impact.

Driver's side SIPS airbag
G024378
Passenger's side SIPS airbag
SIPS airbag deployment (one airbag) occurs
only on the side of the vehicle affected by the
impact. The airbags are not designed to deploy
in all side impact situations.
NOTE
SIPS airbag deployment (one airbag) occurs
only on the side of the vehicle affected by
the impact. The airbags are not designed to
deploy in all side impact situations.
Components in the SIPS airbag systemThis SIPS airbag system consists of a gas gen-
erator, the side airbag modules built into the
outboard sides of both front seat backrests,
and electronic sensors/wiring.

Signals from the park assist system
View in the display (warning for objects front left/
right rear)
Visual indicatorThe audio system’s display gives an overview
of the vehicle’s position in relation to a
detected object.
The marked sectors in the display indicate that
one or more of the sensors has detected an
object. The closer the car symbol comes to a
sector, the closer the vehicle is to the object.
If the infotainment system is switched off, the
park assist system will not be able to provide a
visual indicator. An audible signal will still be
provided.
Audible signalThe 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 there are
objects within this distance both behind and in
front of the vehicle, the tone alternates
between front and rear speakers.
NOTE
The level of the audible signal can be low-
ered/raised with the infotainment volume
control. The level can also be set in the MY
CAR menu system, see page 132.
If the volume of another source from the audio
system is high, this will be automatically low-
ered.
Rear park assist
G017833
The distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The audible 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.

Driving recommendations

tributed so that capacity weight or maximum
permissible axle loads are not exceeded.
Driving through water
•The vehicle can be driven through water up
to a depth of approximately 10 in. (25 cm),
at a maximum speed of 6 mph (10 km/h).
•Take particular care when driving through
flowing water.
•Clean the electrical connections for trailer
wiring after driving in mud or water.
•When driving through water, maintain low
speed and do not stop in the water.
WARNING
After driving through water, press lightly on
the brake pedal to ensure that the brakes
are functioning normally. Water or mud can
make the brake linings slippery, resulting in
delayed braking effect.
CAUTION
•Engine damage will occur if water is
drawn into the air cleaner.
•If the vehicle is driven through water
deeper than 10 in (25 cm), water may
enter the differential and the transmis-
sion. This reduces the oil's lubricating
capacity and may shorten the service
life of these components.
•Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.
•If the engine has been stopped while the
vehicle is in water, do not attempt to
restart it. Have the vehicle towed out of
the water.
Engine and cooling systemUnder special conditions, for example when
driving in hilly terrain, extreme heat or with
heavy loads, there is a risk that the engine and
cooling system will overheat. Proceed as fol-
lows to avoid overheating the engine.
•Maintain a low speed when driving with a
trailer up long, steep hills.
•Do not turn the engine off immediately
when stopping after a hard drive.
WARNING
The cooling fan may start or continue to
operate (for up to 6 minutes) after the engine
has been switched off.
•Remove any auxiliary lights from in front of
the grille when driving in hot weather con-
ditions.
•Do not exceed engine speeds of 4500 rpm
if driving with a trailer in hilly terrain. The oil
temperature could become too high.
Conserving electrical currentKeep the following in mind to help minimize
battery drain:
•When the engine is not running, avoid
using ignition mode II. Many electrical sys-
tems (the audio system, the optional navi-
gation system, power windows, etc) will
function in ignition modes 0 and I. These
modes reduce drain on the battery.
•Please keep in mind that using systems,
accessories, etc., that consume a great
deal of current when the engine is not run-
ning could result in the battery being com-
pletely drained. Driving or having the
engine running for approximately
15 minutes will help keep the battery
charged.
•The optional 12 volt socket in the cargo
area provides electrical current even with

07 Wheels and tires
Tire Sealing System
07
302* Option/accessory, for more information, see Introduction.
Location
IntroductionCertain 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 in the front
tunnel console, on the rear side of the center
console in the rear seat and in the cargo
area*, see page 199.
Accessing the tire sealing systemThe tire sealing system is stowed under the
floor of the cargo area. To access it:
1. Lift the floor hatch in the cargo area.
2. 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.
•After use, stow the tire sealing system
properly to help prevent rattling.
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.
