EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to help provide
optimal braking capacity.
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 a trained and qualified Volvo service
technician 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.

Stability system
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.

Towing
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.

Towing a trailer
General information
Volvo recommends the use of Volvo trailer hitches that are specially designed for the vehicle.
Maximum trailer weights recommended by Volvo are:
Trailers without brakes : 1,540 lbs (700 kg).
Trailers with brakes: 2,000 lbs (900 kg) Observe the legal requirements of the state/province in which the vehicles
are registered.
The maximum recommended hitch tongue load is 165 lbs ( 75 kg).
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.
Trailer towing does not normally present any particular problems, but take into consideration:
Increase tire pressure to recommended full. See the chapter "Wheels and tires."
When your vehicle is new, avoid towing heavy trailers during the first 620 miles (1,000 km).
Maximum speed when towing a trailer: 50 m.p.h. (80 km/h).
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.
If the automatic transmission begins to overheat, a message will be displayed in the information display.
Avoid overload and other abusive operation.
Hauling a trailer affects handling, durability, and economy.
It is necessary to balance trailer brakes with the towing vehicle brakes to provide a safe stop (check and observe
state/local regulations).
Do not connect the trailer's brake system directly to the vehicle's brake system.
More frequent vehicle maintenance is required.
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.
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's 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 your nearest 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
ProCarManuals.com

trailer hitch on the vehicle. The safety wire should never be fastened to or wound around the drawbar ball.
156 06 Starting and driving
Towing a trailer
NOTE
When parking the vehicle with a trailer on a hill, apply the parking brake before putting the gear selector in Park
( P ) or in reverse on models with a manual transmission. Always follow the trailer manufacturer's recommendations
for wheel chocking.
If you use the manual (Geartronic) shift positions while towing a trailer, or if the vehicle is equipped with a
manual transmission, make sure the gear you select does not put too much strain on the engine (using too high a
gear).
The drawbar assembly/trailer hitch may be rated for trailers heavier than the vehicle is designed to tow. Please
adhere to Volvo's recommended trailer weights.
Avoid driving with a trailer on inclines exceeding 15%.
