* 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.

away if you are experiencing any difficulties
programming.
2.
Press and hold both the remote control but-
ton and the HomeLink ®
button to be pro-
grammed.

pressed. The original remote controls may be
used concurrently with HomeLink ®
if desired.
NOTE If the ignition is off, HomeLink
®
works for
30 minutes after the driver's door has been
opened.
WARNING •
If you use HomeLink ®
to open a garage
door or gate, be sure no one is near the
gate or door while it is in motion.
• Do not use HomeLink ®
with any garage
door opener that lacks safety stop and
reverse features as required by US fed-
eral safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the
door to stop and reverse - does not meet
current U.S. federal safety standards. For
more information, contact HomeLink at:

NOTE Always remember to calibrate the Tire Pres-
sure Monitoring System when the wheels
have been changed or the tire inflation pres-
sure has been corrected according to the tire
pressure decal or tire inflation pressure table.
If correct reference values have not been set,
the system cannot issue low tire pressure
alerts correctly.
The vehicle must be stationary with the
engine running to access the calibration but-
ton and to start the calibration process.
WARNING
The exhaust gases contain carbon monoxide,
which is invisible and odorless but very poi-
sonous. For this reason, always perform the
calibration procedure outdoors or in a work-
shop with exhaust gas evacuation equipment.

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).

584 Using the electrical outlets
The 12 V outlet can be used for devices
intended for this such as MP3 players, coolers
and cellular phones.
The high-voltage outlet* can be used for devices
intended for this, such as chargers, laptops, etc. The ignition must be in at least mode I for the
outlets to supply current. The outlets will then be
active as long as there is sufficient charge in the
start battery.
If the engine is turned off and the vehicle is
locked, the outlets will be deactivated. If the
engine is turned off and the vehicle remains
unlocked, the sockets will remain active for up to
7 minutes.
NOTE Bear in mind that using the electrical outlets
when the engine is off could cause the starter
battery to have too low of a charge level,
which could limit other functionality.
Accessories connected to the electrical out-
lets can be activated even when the vehicle
electrical system is off or if preconditioning is
used. For this reason, disconnect plugs when
they are not in use to prevent the starter bat-
tery from becoming discharged.
WARNING •
Do not use accessories with large or
heavy plugs – they could damage the out-
let or come loose while you are driving.
• Do not use accessories that could cause
disruptions to e.g. the vehicle's radio
receiver or electrical system.
• Position the accessory so that there is no
risk of it injuring the driver or passengers
in the event of heavy braking or a colli-
sion.
• Pay attention to connected accessories
as they can generate heat that could burn
passengers or the interior.
Using 12 V outlets1. Remove the stopper (tunnel console) or fold
down the cover (trunk/cargo compartment)
over the socket and plug in the device.
2. Unplug the device and put the stopper back in (tunnel console) or fold up the cover
