NOTE

Recommended hitch tongue load:
not more than 10% of the trailer's
weight. The trailer load should be posi-
tioned so that it does not shift and the
tongue load should be 10% of the trail-
er's weight. However, the tongue load
should not exceed the maximum per-
missible weights indicated in the table
above.

When towing trailers without brakes,
the maximum permissible trailer weight
is 1,700 lbs (750 kg).

If necessary, redistribute the weight of
any cargo in the trailer to avoid exces-
sive weight on the trailer hitch.

The maximum trailer weight listed in the
table for All Wheel Drive models,
5,000 lbs (2250 kg) is only applicable
when there are not more than two occu-
pants in the vehicle, in the front seats,
with a combined weight of 300 lbs
(135 kg), with no other cargo in the vehi-
cle.

The maximum weight listed for Front
Wheel Drive models, 4,000 lbs (1800 kg)
is only applicable when there are not
more than four occupants in the vehicle,
in the front seats and second row of
seats, with a combined weight of
600 lbs (270 kg), with no other cargo in
the vehicle.
NOTE

Vehicles used for towing a trailer on a
regular basis, or for long-distance high-
way towing should be equipped with an
automatic transmission oil cooler and
Volvo's automatic self-leveling system
for the rear suspension. Consult your
Volvo retailer.

Volvo recommends the use of Volvo
trailer hitches that are specially
designed for the vehicle.

All Volvo models are equipped with
energy-absorbing shock-mounted
bumpers. Trailer hitch installation
should not interfere with the proper
operation of this bumper system.

Increase tire pressure to recommended
full inflation pressure. See chapter
"Wheels and tires."

When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).

Engine and transmission are subject to
increased loads. Therefore, engine
coolant temperature should be closely
watched when driving in hot climates or
hilly terrain. Use a lower gear and turn
off the air conditioner if the temperature
gauge needle enters the red range.

NOTE

If the automatic transmission begins to
overheat, a message will be displayed
in the text window.

Hauling a trailer affects handling, dura-
bility, and economy.

It is necessary to balance trailer brakes
with the towing vehicle brakes to pro-
vide a safe stop (check and observe
state/local regulations).

Do not connect the trailer's brake sys-
tem directly to the vehicle's brake sys-
tem.

Remove the ball and drawbar assembly
when the hitch is not being used.

Volvo recommends the use of synthetic
engine oil when towing a trailer over
long distances or in mountainous areas.
NOTE

When parking the vehicle with a trailer
on a hill, apply the parking brake before
putting the gear selector in P. When
starting on a hill, put the gear selector in
D before releasing the parking brake.
Always follow the trailer manufacturer's
recommendations for wheel chocking.

If you use the manual (Geartronic) shift
positions while towing a trailer, make
sure the gear you select does not put
too much strain on the engine (using too
high a gear).
WARNING

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 system, nor a trailer's lighting
system directly to the vehicle lighting
system. Consult a trained and qualified
Volvo service technician for correct
installation.

When towing a trailer, the trailer's safety
wire must be correctly fastened to the
hole or hook provided in the trailer hitch
on the vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.
Smoother starts with a trailerModels equipped with the V8-engine and the
6-speed automatic transmission have a built-
in function that reduces acceleration slightly in
first gear when the vehicle is towing a trailer.
This is done to help avoid wheel spin and to
make starting off smoother.•
This function is activated when the trailer's
electrical connector is plugged into the

Page 154 of 282

06 Starting and drivingTowing a trailer
06154
electrical socket mounted near the trailer
hitch.

The function is automatically deactivated
when the trailer's wiring is disconnected
from the socket. The vehicle will then
accelerate normally.NOTE
Since this function is activated when a con-
nector is plugged into the electrical socket
near the trailer hitch, it will be activated by
any electrical equipment (e.g. bicycle racks
with lighting, etc) that is plugged in, and will
remain active until the equipment is unplug-
ged from the socket.LevelingIf your vehicle is equipped with automatic lev-
eling, the rear suspension always retains the
correct ride height regardless of the load.•
The system adjusts the rear suspension to
the correct level after the vehicle has been
driven a short distance.

When the vehicle is stationary, the rear
suspension lowers, which is normal.

When you pass another vehicle:
The system reacts when you pass another
vehicle at a speed of up to 6 mph (10 km/h)
faster than that vehicle.
When you are passed by another vehicle:
The system reacts if your vehicle is passed by
another vehicle at a speed of up to 43 mph
(70 km/h) faster than your vehicle.
WARNING

BLIS does not function in sharp curves.

BLIS does not function when your vehi-
cle is backing up.

If you are towing a wide trailer, this may
prevent the BLIS cameras from detect-
ing other vehicles in adjacent lanes.
How BLIS functions in daylight and
darknessDaylight
BLIS reacts to the shape of surrounding vehi-
cles. The system is designed to help detect
motor vehicles such as cars, trucks, buses,
motorcycles, etc.
Darkness
BLIS reacts to the headlights of surrounding
vehicles. In order to be detected by BLIS, avehicle in the blind area must have its head-
lights on. This means, for example, that the
system will not detect a trailer without head-
lights that is being towed behind a car or truck.
WARNING

BLIS does not react to cyclists or
mopeds.

BLIS does not react to vehicles that are
standing still.

The function of the BLIS cameras may
be affected by intense light, or when
driving at night in areas where there are
no external sources of light (e.g., street
lights, other vehicles, etc.). In such
cases, the system may react as if the
cameras were obscured.

In both of the above mentioned condi-
tions, a message will appear in the infor-
mation display.

When driving in such conditions, the
system can be temporarily switched off.
For instructions, see page 161.

When the message is no longer dis-
played, BLIS will return to normal func-
tion.

The BLIS cameras have the same limi-
tation as the human eye. In other words,
their "vision is impaired" by adverse
weather conditions such as heavy
snowfall, dense fog, etc.

Properly loading your vehicle will provide maxi-
mum return of vehicle design performance.
Before loading your vehicle, familiarize yourself
with the following terms for deter-mining your
vehicle's weight ratings, with or without a
trailer, from the vehicle's Federal/ Canadian
Motor Vehicle Safety Standards (FMVSS/
CMVSS) label, and the vehicle's tire informa-
tion placard.Curb weightThe weight of the vehicle including a full tank
of fuel and all standard equipment. It does not
include passengers, cargo, or optional equip-
ment.Capacity weightAll weight added to the curb weight, including
cargo and optional equipment. When towing,
trailer hitch tongue load is also part of cargo
weight.
NOTE
For trailer towing information, please refer to
the section "Towing a trailer."Permissible axle weightThe maximum allowable weight that can be
carried by a single axle (front or rear). Thesenumbers 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 + passen-
gers.
A table listing important weight limits for your
vehicle, is in chapter "Dimension and weights".
For the location of the various labels in your
vehicle, see page 258Steps for Determining Correct Load
Limit•
Locate the statement "the combined
weight of occupants and cargo should
never exceed XXX pounds" on your vehi-
cle's placard.

Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.

Subtract the combined weight of the driver
and passengers from XXX kilograms or
XXX pounds.

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 five150 lb. passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400-750 (5 x
150) = 650 lbs.)

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.

If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. Consult this manual
1 to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.
WARNING

Exceeding the permissible axle weight,
gross vehicle weight, or any other
weight rating limits can cause tire over-
heating resulting in permanent defor-
mation 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 vehi-
cle's GVW rating. Replacement tires
with a higher limit than the originals do
not increase the vehicle's GVW rating
limitations.

Tire Sealing System
07``185 Introduction
Certain 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 on the rear side
of the center console (in the rear seat) and in
the cargo area.Accessing the tire sealing systemThe tire sealing system is stowed under the
floor of the cargo area. To access it:
1. Fold up or remove any protective floor cov-
ering or carpet.
2. Open the floor hatch.
3. 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.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.

3. Ensure that the on/off switch is in position
0 (the 0 side of the switch should be
pressed down).
4. Put on the gloves included in the tire seal-
ing system.
WARNING
Contact with the sealing compound may
cause skin irritation. If contact occurs, wash
the affected area immediately with soap and
water.5. Unscrew the orange cover over the bottle
holder and unscrew the cap on the bottle
of sealing compound.
NOTE
Do not break the seal on the bottle. This
occurs automatically when the bottle is
screwed into the holder.6. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep
it securely in place and help prevent sealing
compound leakage. Once in place, the bot-
tle cannot be unscrewed. This must be done
by a trained and qualified Volvo service
technician.7. Remove the valve cap from the tire’s infla-
tion valve and screw the tire sealing sys-
tem’s hose connector onto the valve as
tightly as possible by hand.
8. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
9. Start the vehicle’s engine.
10. Start the tire sealing system’s compressor
by pressing the on/off switch to position I.
WARNING
•Never stand next to the tire being inflated
when the compressor is in operation.•If cracks, bubbles, etc. form on the tire,
switch off the compressor immediately.•If there is visible damage to the sidewall
or the rim, the tire cannot be repaired.
The vehicle should not be driven if this
occurs. Contact a towing service or
Volvo On Call Roadside Assistance if
applicable.NOTE
The air pressure gauge will temporarily
show an increase in pressure to approxi-
mately 88 psi (6 bar) while the sealing com-
pound is being pumped into the tire. The
pressure should return to a normal level
after approximately 30 seconds.11. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch
off the compressor briefly to get a clear
reading from the pressure gauge. The
compressor should not be used for more
than 10 minutes at a time to avoid over-
heating.

07 Wheels and tiresTire Sealing System
07188
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If the pressure remains below 22 psi (1.8
bar) after approximately seven minutes, turn
off the compressor. In this case, the hole is
too large to be sealed and the vehicle should
not be driven.12. Switch off the compressor and disconnect
the electrical wire from the 12-volt socket.
13. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
14. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed
of 50 mph (80 km/h) to distribute the seal-
ing compound in the tire.
NOTE

Safely stow the tire sealing system in a
convenient place as it will soon be used
again to check the tire’s inflation pres-
sure.

The empty bottle of sealing compound
cannot be removed from the bottle
holder. Consult a trained and qualified
Volvo service technician to have the
bottle removed and properly disposed
of.WARNING
If heavy vibrations, unsteady steering
behavior, or noises should occur while driv-
ing, reduce speed and park the vehicle in a
safe place. Recheck the tire for bumps,
cracks, or other visible damage, and
recheck its inflation pressure. If the pressure
is below 19 psi (1.3 bar), do not continue
driving. Have the vehicle towed to a trained
and qualified Volvo service technician.Stage 2: Checking inflation pressure1. Connect the tire sealing system as descri-
bed in stage 1.
2. Refer to the inflation pressure tablesfor the
correct inflation pressure. If the tire needs
to be inflated, start the tire sealing system’s
compressor. If necessary, release air fromthe tire by turning the air release knob
counterclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If you interrupt your trip for more than 1
hour, check the inflation pressure in the
damaged tire again before continuing.Replacing the sealing compound
containerThe sealing compound container must be
replaced if:•
the tire sealing system has been used to
repair a tire

the container’s expiration date has passed
(see the date on decal).
