* Option/accessory. 569
1.

Clean the contact surfaces between the
wheel and the wheel hub.
2. Lift the wheel into place. Tighten the wheel bolts securely.
Do not grease the wheel bolt threads.
3. Lower the vehicle so that the wheel cannot rotate.
4. Tighten the wheel bolts in a crisscross pat- tern (as shown in illustration). It is important
that the wheel bolts are securely tightened.
Tighten to a torque of 140 Nm (103 ft.lbs.).
Use a torque wrench to check torque. 5. Press the plastic covers onto the wheel bolts.
WARNING The wheel bolts may need to be tightened
again several days after a wheel change.
Temperature fluctuations and vibrations can
cause them to loosen slightly.
NOTE
•
After inflating a tire, always replace the
valve cap to help prevent valve damage
caused by gravel, dirt, etc.
• Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.

11
The spare wheel is a Temporary spare and can
be used to temporarily replace a punctured tire
on one of the vehicle's regular wheels. The spare tire is only intended for temporary use.
Replace it with a normal wheel as soon as possi-
ble.
The driving characteristics of the vehicle change
and ground clearance reduces when the spare
wheel is used. Do not wash the vehicle in an
automatic car wash while using the Temporary
Spare.
The recommended tire pressure must be main-
tained regardless of at which position the tempo-
rary spare wheel is used on the vehicle.
If the spare wheel is damaged, a new one can be
purchased from a Volvo retailer.
WARNING Current legislation prohibits the use of the
"Temporary Spare" tire other than as a tem-
porary replacement for a punctured tire. It
must be replaced as soon as possible by a
standard tire. Road holding and handling may
be affected with the "Temporary Spare" in
use. Do not drive faster than 80 km/h
(50 mph).

WARNING •
The vehicle must never be driven with
more than one "Temporary spare" tire
mounted.
• Driving with a spare wheel may alter the
driving characteristics of the vehicle.
Replace the spare wheel with a normal
wheel as soon as possible.
• The spare wheel is smaller than the nor-
mal wheel, which affects the vehicle's
ground clearance. Watch for high curbs
and do not wash the vehicle in an auto-
matic car wash when a spare wheel is
mounted.
• Follow the manufacturer's recommended
tire inflation pressure for the spare wheel.
• On all-wheel drive vehicles, the drive on
the rear axle can be disconnected.
• If the spare wheel is mounted on the
front axle, snow chains must not be used.
• The spare wheel must not be repaired.
CAUTION The vehicle must not be driven with wheels of
different dimensions or with a spare tire other
than the one that came with the vehicle. The
use of different size wheels can seriously
damage your vehicle's transmission.

Follow these instructions regarding handling the
spare wheel. The spare wheel is stored in a bag and should be
secured with two straps onto the floor of the
trunk/cargo compartment when the vehicle is
being driven

. The straps should be strapped
down crosswise over the wheel, attached to the
load anchoring eyelets and pulled taut.
Wheel changing tools are located under the
cargo compartment floor.

586 Sun visors
In the ceiling in front of the driver and front pas-
senger, there are sun visors that can be lowered
and angled to the side as necessary.
The illustration is generic – the design may vary.
The mirror lighting* comes on automatically when
the cover is lifted up.
The mirror frame has a holder for e.g. cards or
tickets.

• 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.

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.

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.587
WARNINGIn a head-on collision at a speed of 50 km/h
(30 mph), an unsecured object weighing 20
kg (44 pounds) can reach a projectile weight
equivalent to 1000 kg (2200 pounds).
WARNING
If objects are loaded higher than the upper
edge of the side windows, leave a 10 cm (4
in.) space between the objects and the win-
dow. Objects placed closer to this could
impede the function of the inflatable curtain
concealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift
during heavy braking and injure people in the
vehicle.
Cover sharp edges and sharp corners with
something soft.
Turn off the engine and apply the parking
brake when loading/unloading long objects.
Otherwise, it is possible for the load to reach
the gear lever or gear selector and move it to
a drive position – which could cause the vehi-
cle to begin rolling.
Extra cargo space
The rear seat backrests can be folded down to
increase cargo compartment space and simplify
loading. If the rear seat backrests are folded down, make sure that no objects loaded into the
vehicle prevent the WHIPS system for the front
seats from functioning correctly.
Raising/lowering the rear end of the
vehicle*
The rear end of the vehicle can be lowered or
raised for easier loading or to facilitate attaching
a trailer*.
The controls for raising/lowering are located at
the rear edge of the cargo compartment's right
side panel. Controls for raising/lowering the rear end of the vehicle.
The controls consist of two buttons ‒ one button
for lowering and one button for raising the rear
end. Press and hold the relevant button until the
desired height is reached.
The rear end of the vehicle cannot be raised
higher than its normal height. The rear end will return to the normal height
when the vehicle begins driving.
NOTE It is not possible to adjust the height of the
vehicle's rear when one or more of the doors
or the hood is open. This does not apply to
the tailgate.
WARNING
Make sure that no people, animals or objects
are found under the vehicle when it is low-
ered. This could endanger life and cause
damage to the vehicle or objects.

588 Roof loads and load carriers
Volvo-developed load carriers are recommended
for carrying loads on the roof of the vehicle.
Volvo load carriers are specially designed to help
prevent damage to your vehicle and help ensure
maximum safety while driving. Volvo load carriers
are available from authorized Volvo retailers.
Carefully follow the installation instructions provi-
ded with the load carriers.
•
Check periodically to ensure that the load
carriers and load are properly secured.
Secure the load firmly using tie straps or
similar.
• Distribute the load evenly throughout the
load carriers. Place heavier cargo at the bot-
tom of the load.
• The vehicle's wind resistance and fuel con-
sumption increase with the size of the load.
• Drive smoothly. Avoid rapid acceleration, hard
braking and fast cornering.
WARNING The vehicle's center of gravity and driving
characteristics are altered by roof loads.
Follow the vehicle's specifications regarding
weights and maximum permitted load.
