vehicle first reaches a speed of approxi-
mately 12 mph (20 km/h). The brake pedal will
pulsate several times and a sound may be
audible from the ABS control module. This is
normal.
To obtain optimal effect from the ABS system,
constant pressure should be kept on the brake
pedal. Do not pump the brake pedal.
The switching of the ABS modulator will be
audible and the brake pedal will pulsate during
braking. Please be aware that ABS does not
increase the absolute braking potential of the
vehicle. While control will be enhanced, ABS
will not shorten stopping distances on slippery
surfaces.ABS with EBD (Electronic Brake Force
Distribution)EBD is an integrated part of the ABS system.
EBD regulates the hydraulic pressure to the
rear brakes to help provide optimal braking
capacity. The brake pedal will pulsate during
braking, which is normal.
If the BRAKE and ABS warning lights come on
at the same time, this could indicate a fault in
the brake system.
1. Stop the vehicle in a suitable place and
switch off the engine.
2. Restart the engine.
•
If both warning lights go off, no further
action is required.
•
If both lights are still on after the engine has
been restarted, switch off the engine again
and check the brake fluid level (see
page 212 for the location of the brake fluid
reservoir).WARNING
If the fluid level is below the MIN mark in the
reservoir or if a
Brake failure – Service
urgent
message is displayed in the text
window: DO NOT DRIVE. Have the vehicle
towed to a trained and qualified Volvo serv-
ice technician and have the brake system
inspected.
•
If the brake fluid level is above the MIN
mark, drive carefully to a trained and quali-
fied Volvo service technician and have the
brake system inspected.
Emergency Brake Assistance (EBA)The EBA function is designed to provide full
brake effect immediately in the event of sud-
den, hard braking. The system is activated by
the speed with which you depress the brake
pedal.
NOTE
•
When the EBA system is activated, the
brake pedal will go down and pressure
in the brake system immediately increa-
ses to the maximum level. You must
maintain full pressure on the brake
pedal in order to utilize the system com-
pletely. There will be no braking effect if
the pedal is released. EBA is automati-
cally deactivated when the brake pedal
is released.
•
When the vehicle has been parked for
some time, the brake pedal may sink
more than usual when the engine is
started. This is normal and the pedal will
return to its usual position when it is
released.

06 Starting and drivingTowing
06150
CAUTION
Vehicles with AWD (All Wheel Drive) with the
front wheels off the ground should not be
towed at speeds about 50 mph (70 km/h) or
for distances longer than 30 miles (50 km).
CAUTION
•
Please check with state and local
authorities before attempting this type
of towing, as vehicles being towed are
subject to regulations regarding maxi-
mum towing speed, length and type of
towing device, lighting, etc.
•
If the vehicle's battery is dead, do not
attempt to start the vehicle by pushing
or pulling it as this will damage the
three-way catalytic converter(s). The
engine must be jump started using an
auxiliary battery (see page 141).
•
If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be
used to secure the vehicle on the flat
bed. Consult the tow truck operator.
WARNING
•
Remember that the power brakes and
power steering will not function when
engine is not running. The braking and
steering systems will function but the
brake pedal pressure required is
3 – 4 times above normal and greater
steering effort must be exerted.
•
The towing eyelets must not be used for
pulling another vehicle out of a ditch or
for any similar purpose involving severe
strain.
•
Do not use the towing eyelets to pull the
vehicle up onto a flat bed tow truck.
G030862
Towing vehicles with front wheel drive/
All Wheel DriveVolvo recommends the use of flat bed equip-
ment.
If wheel lift equipment must be used, please
use extreme caution to help avoid damage to
the vehicle. In this case, the vehicle should
be towed with the rear wheels on the ground
if at all possible.
If it is absolutely necessary to tow the vehicle
with the front wheels on the ground, please
refer to the towing information on the previous
page.
CAUTION
•
Sling-type equipment applied at the
front will damage radiator and air con-
ditioning lines.
•
It is equally important not to use sling-
type equipment at the rear or apply lift-
ing equipment inside the rear wheels;
serious damage to the rear axle may
result.
•
If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be
used to secure the vehicle on the flat
bed. Consult the tow truck operator.

Towing a trailer
06``153
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

06 Starting and driving
Cold weather precautions
06
157
If you wish to check your vehicle before the
approach of cold weather, the following advice
is worth noting:•
Make sure that the engine coolant contains
50 percent antifreeze. Any other mixture
will reduce freeze protection. This gives
protection against freezing down to –31 °F
(–35 °C). See section "Coolant".
•
The use of "recycled" antifreeze is not
approved by Volvo. Different types of
antifreeze must not be mixed.
•
Volvo recommends using only genuine
Volvo antifreeze in your vehicle's radiator.
Your Volvo retailer stocks plenty of Volvo
engine coolant to protect your vehicle dur-
ing cold weather.
•
Try to keep the fuel tank well filled – this
prevents the formation of condensation in
the tank. In addition, in extremely cold
weather conditions it is worthwhile to add
fuel line de-icer before refueling.
•
The viscosity of the engine oil is important.
Oil with low viscosity (thinner oil) improves
cold-weather starting as well as decreas-
ing fuel consumption while the engine is
warming up. For winter use, 5W-30 oil, par-
ticularly the synthetic type
1, is recom-
mended. Be sure to use good quality oil but
do not use cold-weather oil for hard drivingor in warm weather. See section "Engine
oil" for more information.
•
The load placed on the battery is greater
during the winter since the windshield wip-
ers, lighting, etc. are used more often.
Moreover, the capacity of the battery
decreases as the temperature drops. In
very cold weather, a poorly charged bat-
tery can freeze and be damaged. It is there-
fore advisable to check the state of charge
more frequently and spray an antirust oil on
the battery posts.
•
Volvo recommends the use of snow tires
on all four wheels for winter driving – see
section "Wheels and tires."
•
To prevent the washer fluid reservoir
from freezing, add washer solvents con-
taining antifreeze (see page 211 for the
location of the washer fluid reservoir). This
is important since dirt is often splashed on
the windshield during winter driving,
requiring the frequent use of the washers
and wipers. Volvo Washer Solvent should
be diluted as follows:
•
Down to 14 ° F (–10 ° C): 1 part washer
solvent and 4 parts water
•
Down to 5 ° F (–15 ° C): 1 part washer sol-
vent and 3 parts water
•
Down to 0 ° F (–18 ° C):1 part washer sol-
vent and 2 parts water
•
Down to –18 ° F (–28 ° C): 1 part washer
solvent and 1 part water
•
Use Volvo Teflon Lock Spray in the locks.NOTE
Avoid the use of de-icing sprays as they can
cause damage to the locks.W – Winter/Wet driving mode – enhanced
vehicle traction•
Mode W will only function if the gear selec-
tor is in the (D)rive position.
•
Press the button at the base of the gear
selector to engage/disengage this driving
mode.
•
An LED in the button will light up to indicate
that W is engaged and this will also be dis-
played in the instrument panel (see
page 54).
•
This mode may be selected for starting/
moving off on slippery roads.
1Synthetic oil is not used when the oil is changed at the normal maintenance service intervals except at owner request and at additional charge. Please consult your Volvo retailer.

06 Starting and drivingBefore a long distance trip
06158
It is always worthwhile to have your vehicle
checked by a trained and qualified Volvo serv-
ice technician before driving long distances.
Your retailer or service technician will also be
able to supply you with bulbs, fuses, spark
plugs and wiper blades for your use in the event
that problems occur.
As a minimum, the following items should be
checked before any long trip:•
Check that engine runs smoothly and that
fuel consumption is normal.
•
Check for fuel, oil, and fluid leakage.
•
Check transmission oil level
1.
•
Check condition of drive belts.
•
Check state of the battery's charge.
•
Examine tires carefully (the spare tire as
well), and replace those that are worn.
Check tire pressures.
•
The brakes, front wheel alignment, and
steering gear should be checked by a
trained and qualified Volvo service techni-
cian only.
•
Check all lights, including high beams.
•
Reflective warning triangles are legally
required in some states/provinces.
•
Have a word with your Volvo retailer if you
intend to drive in countries where it may be
difficult to obtain the correct fuel.
•
Consider your destination. If you will be
driving through an area where snow or ice
are likely to occur, consider snow tires.
1To prevent injury from contact with hot surfaces, do not inspect your vehicle’s transmission fluid yourself. Have your vehicle’s transmission fluid level inspected by a qualified Volvo service technician.

189
NOTE
•
After use, the sealing compound bottle,
the hose, and certain other system
components must be replaced. Please
consult your Volvo retailer for replace-
ment parts.
•
If the sealing compound bottle’s expi-
ration date has passed, please take it to
a Volvo retailer or a recycling station
that can properly dispose of harmful
substances.
Inflating tiresThe tire sealing system can be used to inflate
the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position
0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s infla-
tion valve and screw the hose connector
onto the valve as tightly as possible by
hand.
5. Connect the electrical wire to the nearest
12-volt socket in the vehicle.6. Start the vehicle’s engine.
WARNING
•The vehicle’s engine should be running
when the tire sealing system is used to
avoid battery drain. Therefore, be sure
the vehicle is parked in a well ventilated
place, or outdoors, before using the sys-
tem.•Children should never be left unattended
in the vehicle when the engine is running.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to
get a clear reading from the pressure
gauge.
8. Refer to the tire inflation tables for the cor-
rect inflation pressure. If the tire needs to
be inflated, start the tire sealing system’s
compressor (press the on/off switch to
position I). If necessary, release air from the
tire by turning the air release knob coun-
terclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
9. Turn off the compressor (press the on/off
switch to position 0) when the correct infla-
tion pressure has been reached.
10. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
11. Disconnect the electrical wire from the 12-
volt socket.
