14. Immediately drive the vehicle at least 3 km
(2 miles) at a maximum speed of 80 km/h
(50 mph) to allow the sealing compound to
seal the tire, and then recheck the inflation
pressure.
NOTE During the tire's first revolution, some sealing
compound may spray out of the puncture
hole.
WARNING
Before driving away, make sure that no one is
near the vehicle who could be sprayed with
sealing compound. Make sure no one is
within 2 meters(7 feet) of the vehicle.
15. Rechecking the inflation pressure
Connect the hose to the tire's valve and
screw the hose connector onto the valve as
far as possible. The compressor must be
switched off. 16.

Check the inflation pressure on the air pres-
sure gauge.
• If the pressure is under 1.3 bar (19 psi),
the tire is not sufficiently sealed. The vehi-
cle should not be driven. Call roadside
assistance to have the vehicle towed.
• If the inflation pressure is higher than
1.3 bar (19 psi), the tire must be inflated
to the inflation pressure specified on the
tire pressure decal on the driver's side
door pillar (1 bar = 100 kPa = 14.5 psi). If
the inflation pressure is too high, use the
air release valve to release air.
NOTE Replace the sealing compound bottle and
hose after use. Volvo recommends having
these replaced by an authorized Volvo work-
shop.
WARNING
Check inflation pressure regularly.
Volvo recommends driving to the nearest author-
ized Volvo workshop to have the tire replaced/
repaired. Inform the workshop that the tire con-
tains sealing compound.
WARNING After using the tire sealing system, the vehicle
should not be driven farther than approxi-
mately 200 km (120 miles).
NOTE
The compressor is an electric device. Follow
local regulations for disposal.

WHEELS AND TIRES
578Determining the vehicle's permitted
weight
Properly loading your vehicle will provide maxi-
mum return of vehicle design performance.
Weight designationsBefore loading your vehicle, familiarize yourself
with the following terms for determining your
vehicle's weight ratings, with or without a trailer,
from the vehicle's Federal/Canadian Motor Vehi-
cle Safety Standards (FMVSS/CMVSS) label, and
the vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of
fuel and all standard equipment. It does not
include passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including
cargo and optional equipment. When towing, tow-
bar weight is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be car-
ried by a single axle (front or rear). These num-
bers are shown on the Federal/Canadian Motor
Vehicle Safety Standards (FMVSS/CMVSS) label.
The total load on each axle must never exceed its
maximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight of occupants and cargo should never exceed
XXX kg or XXX lbs." on your vehicle's plac-
ard.
2. Determine the combined weight of the driver and passengers that will be riding in your
vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and luggage load capacity.
For example, if the "XXX" amount equals
1400 lbs. and there will be five 150 lb. pas-
sengers in your vehicle, the amount of availa-
ble cargo and luggage load capacity is 650
lbs. (1400 - 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your
vehicle. Consult this manual to determine
how this reduces the available cargo and lug-
gage load capacity of your vehicle.
WARNING •
Exceeding the permissible axle weight,
gross vehicle weight, or any other weight
rating limits can cause tire overheating
resulting in permanent deformation or
catastrophic failure.
• Do not use replacement tires with lower
load carrying capacities than the tires that
were original equipment on the vehicle
because this will lower the vehicle's GVW
rating. Use only tires with the correct load
carrying capacity. Consult your Volvo
retailer for information.

• Passenger compartment interior (p. 580) Cargo compartment
The vehicle has a flexible cargo compartment
that makes it possible to carry and secure large
objects.
The cargo compartment capacity can be consid-
erably increased by folding down the backrests in
the second and third rows* of seats. To make
loading and unloading easier, the rear section of
the vehicle can be raised and lowered using the
level control function*. Use the load anchoring
eyelets or grocery bag holders to help secure
objects in place, and the retractable cargo com-
partment cover* to help conceal objects in the
cargo compartment.
If the vehicle is equipped with a temporary spare
tire, this is secured to the cargo compartment
floor under the cover. The towing eyelet and tire
sealing system are located under the cargo com-
partment floor.

• Installing and removing the cargo compart-
ment cover* (p. 589) Loading recommendations
There are a number of things to consider when
carrying loads in or on the vehicle. Load-carrying capacity is determined by the vehi-
cle's curb weight. The total weight of all passen-
gers and any installed accessories reduces the
vehicle's load-carrying capacity by the corres-
ponding amount.
WARNING The vehicle's driving characteristics change
depending on the weight and position of the
load.
Loading in the trunk and cargo
compartment
•
Position objects so they are pressing against
the rear seat backrests.
• Distribute the load evenly.
• Heavy objects should be positioned as low
as possible. Avoid placing heavy objects on
folded-down seat backrests.
• Cover sharp corners with a soft cloth or simi-
lar to help prevent damage to the upholstery.
• Use the load anchoring eyelets and tension-
ing straps or similar to secure all objects.

592 Installing and removing the steel
cargo grid*
The steel cargo grid prevents loads or pets in
the cargo compartment from being thrown for-
ward into the passenger compartment. For safety reasons, the steel grid must always be
installed and secured correctly.
WARNING
Under no circumstances may a person be in
the cargo compartment when the vehicle is
moving. Heavy braking or a collision could
lead to serious injury.
The steel grid consists of the grid itself and two
separate mounting brackets. Each of the mount- ing brackets has a screw cover and two plastic
sleeves for the grid.
WARNING The steel cargo grid may only be used in the
rear position described here. The ceiling
attachment points behind the front seats are
not intended to anchor the steel grid.
WARNING
For safety reasons, the third-row seats
4
must
be folded down when the steel cargo grid is
mounted in the vehicle.
CAUTION The steel cargo grid and the cargo compart-
ment cover cannot be mounted at the same
time.
Installation1. Fold down the rear seats and lift in the steel
grid through one of the rear doors or the tail-
gate. The curved (convex) side of the grid
should face toward the cargo compartment
and the hooks on each side of the grid
should face upward. The mounting brackets
and plastic sleeves are not needed in this
step. 2. Press one of the grid's hooks into the larger
hole in the ceiling attachment point (1).
Grasp the grid near the hook and pull/push it
into the smaller hole (2).
>

The hook is now secured in the attach-
ment point.
3. Repeat step 2 above to secure the other hook in the attachment point on the opposite
side.
WARNING Make sure the cargo grid's hooks are securely
attached in the ceiling attachment points to
help ensure the grid does not come loose.

Monthly:
•
Check cold tire pressure in all tires. Inspect
the tires for wear.
• Check that engine coolant and other fluid
levels are between the indicated "min" and
"max" markings.
• Clean interior glass surfaces with a glass
cleaner and soft paper towels.
• Wipe driver information displays with a soft
cloth.
• Visually inspect battery terminals for corro-
sion. Corrosion may indicate a loose terminal
connector, or a battery near the end of its
useful service life. Consult your Volvo retailer
for additional information.
As needed:
Wash the car, including the undercarriage, to
reduce wear that can be caused by a buildup of
dirt, and corrosion that can be caused by salt res-
idues.

workshop over Wi-Fi
Volvo workshops have a designated Wi-Fi net-
work for secure data transfer between your vehi-
cle and the workshop. Your visit to the workshop
will be easier and more effective when diagnos-
tics information and software can be transferred
over the workshop's network.
When you arrive at the workshop, your technician
can connect your vehicle to the workshop's Wi-Fi
network to perform troubleshooting and down-
load software. For this type of communication,
the vehicle only connects to the workshop's net-
work. The vehicle can only be connected to the
designated workshop networks, not to any other
network, e.g. your home network.
Manual connection to workshop Wi-FiManual connection is usually performed by a
service technician. Because the technician uses
the buttons on your remote key to connect the
vehicle, it is important that you bring a key with
buttons when taking the vehicle in to a workshop.
Pressing the lock button on the remote key three
times will connect the vehicle to the workshop's
Wi-Fi network.
When the car is connected to a Wi-Fi network,
the symbol appears in the center display.

Coolant helps keep the combustion engine at
the right operating temperature. The heat trans-
ferred from the engine to the coolant can be
used to warm the passenger compartment.
When refilling coolant, follow the instructions on
the package. Never fill the cooling system with
only water. The risk of freezing is increased with
too low or too high amounts of coolant.
If there is coolant under the vehicle, smoke from
the cooling system, or if more than 2 liters (about
2 quarts) of coolant has been added to the sys-
tem, there could be something wrong with the
cooling system and starting the vehicle could
damage the engine. Call a tow truck and do not
attempt to start the engine.
WARNING The coolant may be very hot. Never unscrew
the cap when the coolant is hot. If coolant
must be filled, unscrew the expansion tank
cap slowly to relieve overpressure. Coolant expansion tank.
