The vehicle can be lowered or raised to make it
easier to load or for passengers to get in and
out.
Turn off leveling control before lifting the vehicle
with a jack to help avoid problems with the
pneumatic suspension.
Adjusting loading mode Use the buttons in the cargo compartment to
raise or lower the rear section of the vehicle to
facilitate loading or unloading the vehicle or con-
necting or disconnecting a trailer.

is opened and will resume after a slight
delay when the door has been closed.)
When the engine is started and the vehi-
cle begins to move, the level will be raised
to the height set by the selected drive
mode.
Disable Leveling Control
In certain situations, this function must be turned
off, e.g. before the vehicle is raised using a jack*.
The level difference caused by raising the vehicle

•Leveling control* and suspension (p. 450)
• Loading recommendations (p. 586) Low Speed Control
The low-speed function, Low Speed Control
(LSC), facilitates and improves control and trac-
tion on rough roads and slippery surfaces, e.g.
when towing a trailer on grass or up boat ramps.
The function is included in the Off Road drive
mode.
Low Speed Control is designed for driving on
rough roads and when towing trailers at low
speeds, up to approximately 40 km/h (25 mph).
When driving at low speeds, LSC prioritizes low
gears and all-wheel drive to help avoid wheel spin
and improve traction on all wheels. The accelera-
tor pedal will be less responsive to improve trac-
tion and speed control at low speeds.
The function is activated together with Hill
Descent Control (HDC), which makes it possible
to control speed going down steep hills using the
accelerator pedal and reduces the need to use
the brake pedal. The system makes it possible to
maintain a low and uniform speed when driving
down steep hills.

STARTING AND DRIVING
* Option/accessory.473
CAUTION•
Bumper-attached trailer hitches must not
be used on Volvos, nor should safety
chains be attached to the bumper.
• Trailer hitches attaching to the vehicle
rear axle must not be used.
• Never connect a trailer's hydraulic brake
system directly to the vehicle brake sys-
tem, nor a trailer's lighting system directly
to the vehicle lighting system. Consult
your nearest authorized Volvo retailer for
correct installation.
• When towing a trailer, the trailer's safety
chains or wire must be correctly fastened
to the attachment points provided in the
trailer hitch on the vehicle. The safety
chain or wire must never be fastened to
or wound around the towing ball.
NOTE The optional detachable trailer hitch may not
be available in all markets or on all models.
Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer,
driving at high altitudes and fuel quality are
factors that significantly increase a vehicle's
fuel consumption.
Trailer weights
WARNING Please adhere to the recommendations provi-
ded for trailer weight. If the recommendations
are not followed, the vehicle and trailer may
be difficult to control during evasive maneu-
vers and braking.
NOTE
The specified maximum trailer weights are
those permitted by Volvo. National vehicle
regulations may set additional restrictions on
trailer weight and speed. The trailer hitches
may be certified for higher towing weights
than the vehicle is permitted to tow.
Self-leveling suspension*The vehicle's self-leveling system attempts to
keep the vehicle at a constant level, regardless of
load (up to the maximum permitted weight).
When the vehicle is stationary, the rear end of the
vehicle will be slightly lowered, which is normal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of overheat-
ing when driving with a trailer. If overheating of
the engine and drive system is detected, a warn-
ing symbol will illuminate in the instrument panel
along with a message.The automatic transmission selects the optimal
gear for the current load and engine speed.
Steep inclines
Do not lock the automatic transmission into a
higher gear than what the engine can handle ‒ it
is not always preferable to drive in high gears at
low rpm.
Parking on a hill
1. Depress the brake pedal.
2. Apply the parking brake.
3. Put the gear selector in P.
4. Release the brake pedal.
Put chocks behind the wheels when the vehicle
is parked on a hill with a trailer attached.
Starting on a hill
1. Depress the brake pedal.
2. Put the gear selector in D.
3. Release the parking brake.
4. Release the brake pedal and start driving.

The cover turns along its center line and
can then be removed. 3. Screw in the towing eyelet until it reaches its
stop. Fasten the eyelet securing by, for exam-
ple, inserting a lug wrench* through it and
using this as a lever.
CAUTION It is important that the towing eye is screwed
in securely as far as possible.
Removing the towing eyelet:
–
After use, unscrew the towing eyelet and
return it to its storage location.
Replace the cover on the bumper.

• Tool kit (p. 564) Recovery
This section refers to transporting the vehicle
with a tow truck or similar vehicle. Call a professional towing service for assistance.
In certain conditions, the towing eyelet can be
used to pull the vehicle onto a flatbed tow truck.
CAUTION Note that vehicles with Twin Engine must
always be towed raised with all wheels on the
tow truck.
For vehicles equipped with leveling control*:
If the vehicle is equipped with pneumatic suspen-
sion, this feature must be turned off before the
vehicle is lifted onto a tow truck. Turning off the
function in the center display.
1. Tap Settings in the Top view.
2.

Tap My Car Parking Brake and
Suspension .
3. Select Disable Leveling Control.
The vehicle's location and ground clearance
determine if it can be lifted onto a tow truck. If
the incline of the tow truck is too steep or if the
ground clearance under the vehicle is insufficient,
attempting to pull it up may result in damage. In
this case, the vehicle should only be lifted with
the tow truck's lifting equipment.

WHEELS AND TIRES
}}
* Option/accessory. 565
Jack*
The jack can be used to lift the vehicle to e.g.
change a wheel. The illustration is generic – the design may vary.
CAUTION •
When not in use, the jack* should be kept
in its storage compartment under the
cargo compartment floor.
• The jack provided with your vehicle is
intended to be used only in temporary sit-
uations such as changing wheels in the
event of a flat tire. Only the jack that
came with your particular model should
be used to lift the vehicle. If the vehicle
needs to be lifted more frequently or for a
prolonged period, using a garage jack or
hoist is recommended. Always follow this
device's instructions for use. The jack needs to be cranked together to the
correct position in order to fit.
Models with leveling control*
If the vehicle is equipped with the optional pneu-
matic suspension, it must be turned off before
the vehicle is lifted on a jack.

Tool kit (p. 564) Wheel bolts
The wheel bolts hold the wheel in place on the
wheel hub.
CAUTION The wheel bolts should be tightened to
140 Nm (103 ft. lbs.). Over-tightening or
under-tightening could damage the threaded
joints.
Only use rims that have been tested and
approved by Volvo and are included in Volvo's
original product range.
Use a torque wrench to check that the wheel
bolts are tightened correctly.
Do not grease the wheel bolt threads.
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.
Locking wheel bolts*A tool for removing the locking wheel bolts is
located in the foam block under the cargo com-
partment floor.

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.
