Introduction
Volvo recommends the use of Volvo trailer hitches that are specially designed for thevehicle.
NOTE
See page 385 for the maximum trailer and tongue weights recommended by Volvo.
•Observe the legal requirements of the state/province in which the vehicles are
• All Volvo models are equipped withenergy-absorbing shock-mounted bump-ers. Trailer hitch installation should notinterfere with the proper operation of thisbumper system.
Trailer towing does not normally present any particular problems, but take into considera-tion: • Increase tire pressure to recommended full pressure. See the tire inflation tableon page 316.
• When your vehicle is new, avoid towingheavy trailers during the first 620 miles(1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine cool-ant temperature should be closely watched when driving in hot climates orhilly terrain. Use a lower gear and turn offthe air conditioner if the temperaturegauge needle enters the red range.
• If the automatic transmission begins tooverheat, a message will be displayed inthe text window.
• Avoid overload and other abusive opera-tion.
• Hauling a trailer affects handling, durabil-ity, and economy.
• It is necessary to balance trailer brakeswith the towing vehicle brakes to providea safe stop (check and observe state/local regulations).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch isnot being used.
WARNING
• Bumper-attached trailer hitches must not be used on Volvos, nor shouldsafety chains be attached to thebumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulicbrake system directly to the vehiclebrake system, nor a trailer's lightingsystem directly to the vehicle lightingsystem. Consult your nearest author-ized Volvo retailer for correct installa-tion.
• When towing a trailer, the trailer'ssafety wire must be correctly fastenedto the hole or hook provided in thetrailer hitch on the vehicle. The safetywire should never be fastened to orwound around the drawbar ball.

08 Wheels and tires
Temporary Spare

Spare tire
The spare tire in your vehicle1
is called a
"Temporary Spare". Recommended tire pressure (see the placard on the B-pillar or on the fuel filler door) shouldbe maintained irrespective of which positionon the vehicle the temporary spare tire isused on. In the event of damage to this tire, a new one can be purchased from your Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as atemporary replacement for a puncturedtire. It must be replaced as soon as possi-ble by a standard tire. Road holding andhandling may be affected with the "Tem-porary Spare" in use. Do not exceed50 mph (80 km/h).
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tireother than the one that came with the vehi-cle. The use of different size wheels canseriously damage your car's transmission.
1 Not on models equipped with the Tire sealing system.
