be longer.
A warning light in the instrument panel will light up to warn the driver that a fault has occurred.
If this light comes on while driving or braking, stop immediately and check the brake fluid level in the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal - do not pump the brakes.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a brake system message is shown in the information
display: DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the
brake system inspected.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Never let the vehicle roll
to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed approximately five times harder than usual to
make up for the lack of power assistance. This can happen for example when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The brake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect on the brake discs and
pads. This will cause a delay in braking effect when the pedal is depressed. To avoid such a delay when the brakes are
needed, depress the pedal occasionally when driving through rain, slush, etc. This will remove the water from the
brakes. Check that brake application feels normal. This should also be done after washing or starting in very damp or
cold weather.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or hilly areas, or when towing a trailer. Vehicle
speed is usually slower, which means that the cooling of the brakes is less efficient than when driving on level roads.
To reduce the strain on the brakes, shift into a lower gear and let the engine help with the braking. Do not forget that if
you are towing a trailer, the brakes will be subjected to a greater than normal load.
Anti-lock brakes (ABS)
The Anti-lock Braking System (ABS) helps to improve vehicle control (stopping and steering) during severe braking
conditions by limiting brake lockup. When the system "senses" impending lockup, braking pressure is automatically
modulated in order to help prevent lockup that could lead to a skid.
The system performs a self -diagnostic test when the engine is started and when the vehicle first reaches a speed
of approximately 12 m.p.h. (20 km/h) . The brake pedal will pulsate several times and a sound may be audible from
the ABS control module. This is normal.
149 06 Starting and driving
Brake system

For optimal ABS braking effect:
1. Press down on the brake pedal with full force. The pedal will pulsate.
2. Steer the vehicle in the direction of travel and keep the brake pedal depressed.
Electronic Brake Force Distribution (EBD)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to help provide
optimal braking capacity.
NOTE
To obtain optimal effect from the ABS system:
Keep constant pressure 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.
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will still function)
and the vehicle should be driven cautiously to a trained and qualified Volvo service technician for inspection.
WARNING
If the BRAKE and ABS warning symbols light at the same time, there may be a problem in the brake system. If the
brake fluid level is normal in these circumstances, drive carefully to the nearest Volvo workshop to have the brake
system checked.
Emergency Brake Assistance - EBA
EBA is designed to provide full brake effect immediately in the event of sudden, hard braking. The system is activated
by the speed with which the brake pedal is depressed.
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately
increases to the maximum level. Maintain full pressure on the brake pedal in order to utilize the system completely.
EBA is automatically deactivated when the brake pedal is released.
NOTE
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately
increases to the maximum level. You must maintain full pressure on the brake pedal in order to utilize the system
completely. There will be no braking effect if the pedal is released. EBA is automatically 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.
150 06 Starting and driving
Dynamic Stability Traction Control
Dynamic Stability Traction Control (DSTC)

The stability system consists of a number of functions designed help reduce wheel spin, counteract skidding, and to
generally help improve directional stability.
A pulsating sound will be audible when the system is actively operating and is normal.
Traction control - TC
This function is designed to help reduce wheel spin by transferring power from a drive wheel that begins to lose
traction to the wheel on the opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of the stability system's permanent functions and cannot be switched off.
A - thumbwheel
B - RESET button
Spin control (SC)
The spin control function is designed to help prevent the drive wheels from spinning while the vehicle is accelerating.
Under certain circumstances, such as when driving with snow chains, or driving in deep snow or loose sand, it may be
advisable to temporarily switch off this function for maximum tractive force.
Temporarily switching off Spin control
1. Turn the thumbwheel (A) on the left-side steering wheel lever until the DSTC menu is displayed.
2. Hold down the RESET button (B) to toggle between DSTC SPIN CONTROL ON or OFF.
NOTE
The message DSTC SPIN CONTROL OFF indicates that the stability system's spin control function has
temporarily been switched off.
The stability control indicator light will illuminate and remain on until spin control has been reactivated.
The spin control function is automatically enabled each time the engine is started.
DSTC ON indicates that all system functions are active.
Active yaw control - AYC
This function helps maintain directional stability, for example when cornering, by braking one or more of the wheels if
the vehicle shows a tendency to skid or slide laterally.

151 06 Starting and driving
Dynamic Stability Traction Control
This is one of the stability system's permanent functions and cannot be switched off.
WARNING
The car's handling and stability characteristics will be altered if the DSTC system functions have been disabled.

Emergency towing
The towing eyelet is located under the floor of the cargo area. This eyelet must be screwed into the positions provided
on the right sides of either the front or rear bumper (see illustrations).
To attach the towing eyelet:
1. Press the mark on the lower edge of the cover (1) to open it.
2. Screw the towing eyelet (3) in place first by hand and then using the tire iron until it is securely in place.
After the vehicle has been towed, the eyelet should be removed and returned to the tool bag. Press the cover back into
position.
Towing a vehicle with all four wheels on the ground
WARNING
Volvo does not recommend towing a disabled vehicle behind another vehicle. Significant difficulty in steering and
braking, combined with unfavorable weather, traffic, and road conditions may make it impossible to maintain vehicle
control.
1. Apply the parking brake.
2. Insert the key into the ignition to unlock the steering wheel. The steering wheel must be unlocked. With the engine
off and the vehicle at a standstill, great effort will be required to turn the steering wheel.
WARNING

Towing a vehicle with a locked steering wheel will make the vehicle impossible to steer.
3. Turn the ignition key to position II.
4. Place the gear selector in neutral. For vehicles with automatic transmissions, follow instruction on page 147
,
"Shiftlock override" to allow the gear selector to be moved from the Park position.
5. Keep firm pressure on the brake pedal while releasing the parking brake.
6. When towing has been completed, return the gear selector to Park (automatic) or Reverse (manual) and apply the
parking brake.
The following points should also be observed:
Never exceed 50 mph (80 km/h). Never exceed local towing speed limits and heed all local towing restrictions.
Never tow farther than 50 miles (80 km) .
Keep the tow rope taut at all times while the vehicle is in motion.
The disabled vehicle should be towed in the forward direction only.
153 06 Starting and driving
Towing
WARNING
Never allow a vehicle to be towed without a driver behind the wheel of the disabled vehicle.
Never remove the key from the ignition while the vehicle is moving. The steering wheel could lock, making it
impossible to steer the vehicle.
When the engine is not running, steering resistance and the effort needed to apply the brakes will be great.
Never attempt to tow a vehicle with a dead battery at night.
CAUTION
Check with state and local authorities before attempting this type of towing, as vehicles being towed are subject to
regulations regarding maximum towing speed, length and type of towing device, lighting, marker flags, etc.
Never attempt to push- or tow-start a vehicle with a dead battery. This would inject unburned fuel into the three-
way catalytic converter(s), causing overheating, backfiring, and damage. See page 154
for instructions on jump
starting the vehicle.
Towing vehicles with front wheel drive
Volvo recommends the use of flat bed equipment for towing vehicles with front wheel drive. 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.
Sling-type equipment applied at the front will damage radiator and air conditioning lines.
It is equally important not to use sling -type equipment at the rear or apply lifting 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.
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 - 5 times above normal and greater
steering effort must be exerted.
The towing eyelets must not be used for pulling the 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.
154 06 Starting and driving
Jump starting
Follow these instructions to jump start your vehicle's dead battery or to jump start another vehicle's dead battery using
your vehicle. If the 12-volt auxiliary battery to be used is in another vehicle, check that the vehicles are not touching to
prevent premature completion of a circuit. Be sure to follow jump starting instructions provided for the other vehicle.
To jump start your vehicle:
1. Switch off the ignition.
2. First connect the auxiliary battery positive (+) terminal (1) to the positive (+) terminal in your vehicle's battery (2),

155 06 Starting and driving
Transporting loads
Loading the vehicle
Your vehicle's load-carrying capacity is affected by factors such as:
the number of passengers
tire inflation
the amount of optional or accessory equipment installed
the amount of cargo
See the chapter "Wheels and tires" for more detailed information.
Before loading the car, turn off the engine, and apply the parking brake when loading or unloading long objects. The
gear selector can be inadvertently knocked out of position by long cargo, causing the vehicle to move.
Keep the following in mind when loading the vehicle:
Load the cargo in the cargo area against the rear seat backrest.
Load heavy cargo as low as possible.
Center wide loads.
Secure all cargo with restraining straps anchored to the load securing eyelets.
Cover sharp edges on the load.
Seats can be folded down to extend the cargo compartment. See page 108.
WARNING
Remember that an object weighing 44 lbs (20 kg) produces a force of 2,200 lbs (1,000 kg) in a head-on collision
at 30 m.p.h. (50 km/h)!
When the rear backrest(s) are folded down, the vehicle should not be loaded to a level higher than 2 in. (5 cm)
below the upper edge of the rear side windows. Objects placed higher than this level could impede the function of
the Volvo Inflatable Curtain.
Load carriers (accessory)
Load carriers are available as Volvo accessories. Follow the installation instructions supplied with the load carriers.
Observe the following points when using load carriers:

The system is activated automatically when the vehicle is started. The indicator light in the button in the center console
illuminates.
The front park assist system is active from the time the engine is started until the vehicle exceeds a speed of
approximately 10 mph (15 km/h). It is also active when the vehicle is backing up.
Rear park assist is active when the engine is running and reverse gear has been selected.
Rear park assist
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The signal comes from the rear speakers.
The system must be deactivated when towing a trailer, carrying bicycles in a rear-mounted carrier, etc, which could
trigger the rear park assist system's sensors.
NOTE
Rear park assist is deactivated automatically when towing a trailer if Volvo genuine trailer wiring is used.
Front park assist
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audible signal comes from the audio
system's front speakers.
It may not be possible to combine auxiliary headlights and front park assist since these lights could trigger the system's
sensors.

Washing and cleaning the car
Washing the car
The following points should be kept in mind when washing and cleaning the car:
The vehicle should be washed at regular intervals since dirt, dust, insects and tar spots adhere to the paint and may
cause damage. To help prevent corrosion, it is particularly important to wash the vehicle frequently in the wintertime
when salt has been used on the roads.
Avoid washing your vehicle in direct sunlight. Doing so may cause detergents and wax to dry out and become
abrasive. To avoid scratching, use lukewarm water to soften the dirt before you wash with a soft sponge, and plenty of
sudsy water.
Bird droppings : Remove from paintwork as soon as possible. Otherwise the finish may be permanently damaged.
A detergent can be used to facilitate the softening of dirt and oil.
A water-soluble grease solvent may be used in cases of sticky dirt. However, use a wash place equipped with a
drainage separator.
Dry the vehicle with a clean chamois and remember to clean the drain holes in the doors and rocker panels.
Tar spots can be removed with kerosene or tar remover after the vehicle has been washed.
A stiff-bristle brush and lukewarm soapy water can be used to clean the wiper blades. Frequent cleaning of the
windshield and wiper blades improves visibility considerably and also helps prolong the service life of the wiper
blades.
Wash off the dirt from the underside (wheel housings, fenders, etc).
In areas of high industrial fallout, more frequent washing is recommended.
After cleaning the engine, the spark plug wells should be inspected for water and blown dry if necessary.
