Towing a trailer

305
FunctionA vehicle towing a trailer may begin to sway for various reasons. Normally this only occursat high speeds but, for example, if the traileris overloaded or if the load is unevenly dis-tributed in the trailer, there is risk of swayingat speeds between approximately 45-55 mph(70-90 km/h). Swaying may be caused by factors such as: •The vehicle and trailer are hit by a sud- den, strong crosswind
• The vehicle and trailer are traveling on anuneven road surface or drive over a bump
• Sudden movements of the steering wheel
Facts about TSA
•
TSA intervenes at speeds above approxi-mately 40 mph (60 km/h)
• The DSTC symbol (
) in the instru-
ment panel will flash when TSA is working
• If the driver switches off the DSTC sys- tem's Spin Control function, TSA will alsobe switched off (but will be on again thenext time the engine is started)
• TSA may not intervene when the vehicleand trailer begin to sway if the driver triesto compensate for the swaying motion bymoving the steering wheel rapidly
How TSA worksOnce swaying has begun, it can be very diffi- cult to stop, which makes it difficult to controlthe vehicle and trailer. The TSA system continuously monitors the vehicle's movements, particularly lateralmovement. If the system detects a tendencyto sway, the brakes are applied individuallyon the front wheels, which has a stabilizingeffect on the vehicle and trailer. This is oftenenough to enable the driver to regain controlof the vehicle. If this is not adequate to stop the swaying motion, the brakes are applied to all of thewheels on the vehicle and on the trailer if it isequipped with brakes, and engine power istemporarily reduced. As the swaying motionbegins to decrease and the vehicle-trailerhave once again become stable, TSA will nowstop regulating the brakes/engine power andthe driver regains control of the vehicle.

Towing eyelet
Attaching the towing eyelet
Attaching the towing eyeletThe towing eyelet is located under the floor of the cargo area, with the spare tire.This eyelet must be screwed into thepositions provided on the right sides ofeither the front or rear bumper (see illus-tration).
There are two different types of covers over the openings for the towing eyeletand they have to be opened differently.
• If the cover has a notch, insert a coin, etc., into the notch and pry open theedge of the cover. Open the covercompletely and remove it.
• If the cover has a mark along one edgeor in a corner, press the mark whileprying out the opposite side/cornerusing a coin, etc. Open the cover andremove it.
Screw the towing eyelet in place, first by hand and then using the tire iron until it issecurely in place. After the vehicle has been towed, the eyelet should be removed and returned to its stor-age location. Press the cover for the attachment point back into position.WARNING
• When the vehicle is being towed, the ignition should be in mode
II (in mode
I , all of the vehicle's airbags are deac-
tivated). See page 89 for more infor-mation about ignition modes.
• Never remove the remote key from theignition slot when the vehicle is beingtowed. For vehicles with keyless drive,the remote key must remain inside thevehicle.
• The power brakes and power steeringwill not function when the engine is notrunning. Approximately 5 times morepressure will be required on the brakepedal and the steering wheel will beconsiderably harder to turn.
• The towing eyelets must not be usedfor pulling the vehicle out of a ditch orfor any similar purpose involvingsevere strain.

Having the vehicle towed by a tow truck
Call for professional help from an authorized towing company. Volvo recommends the useof flat bed equipment.
CAUTION
In certain conditions, the towing eyelet may be used to pull the vehicle onto aflatbed tow truck.
• The vehicle's position and ground clearance determine if it can be pulledup onto a flatbed tow truck using thetowing eyelet.
• If the angle of the tow truck’s ramp istoo steep or the ground clearanceunder the vehicle is insufficient, dam-age could occur by attempting to pullthe vehicle using the towing eyelet.
• If necessary, lift the vehicle using thetow truck’s lifting device.
WARNING
No person or object should be behind the tow truck while the vehicle is being pulledup onto the flatbed.
CAUTION
•The vehicle should always be towed in the forward direction.
• Vehicles with All Wheel Drive (AWD)*that are being towed with the frontwheels off the ground should not betowed at a speed above approx.45 mph (70 km/h) and should not betowed farther than 30 miles (50 km).
Towing the vehicle
1. With the remote key fully pressed into the
ignition slot 1
, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II.
2. The remote key must remain in the igni- tion slot 2
for the entire time that the vehi-
cle is being towed.
3. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This willhelp prevent jarring movements of thevehicle being towed.
4. Be prepared to apply the brakes to stop the vehicle being towed.
CAUTION
General towing precautions:
• Please check with state and local authorities before attempting this typeof towing, as vehicles being towed aresubject to regulations regarding maxi-mum towing speed, length and type oftowing device, lighting, etc.
• If the vehicle's battery is dead, seepage 125 to provide current for releas-ing the electric parking brake and tomove the gear selector from the
P
position to N. If this is not possible,
see page 130 for information aboutmanually overriding the shiftlock sys-tem to move the gear selector from P
to N.
• Maximum speed: 50 mph (80 km/h).Do not exceed the maximum allowabletowing speed.
• Maximum distance with front wheelson ground: 50 miles (80 km).
• The vehicle should only be towed inthe forward direction.

Winter driving conditions
Snow chainsSnow chains can be used on your Volvo with the following restrictions:• Snow chains should be installed on front wheels only. Use only Volvo approvedsnow chains.
• If accessory, aftermarket or "custom"tires and wheels are installed and are of asize different than the original tires andwheels, chains in some cases CANNOTbe used. Sufficient clearances betweenchains and brakes, suspension and bodycomponents must be maintained.
• Some strap-on type chains will interferewith brake components and thereforeCANNOT be used.
• All Wheel Drive models
: Snow chains
should only be installed on the frontwheels.
• Certain size tires may not allow theassembly of snow chains/traction devi-ces.
Consult your Volvo retailer for additional
snow chain information.
CAUTION
• Check local regulations regarding the use of snow chains before installing.
• Use single-sided snow chains only.
• Always follow the chain manufactur-er's installation instructions carefully.Install chains as tightly as possible andretighten periodically.
• Never exceed the chain manufactur-er's specified maximum speed limit.(Under no circumstances should youexceed 31 mph (50 km/h).
• Avoid bumps, holes or sharp turnswhen driving with snow chains.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns aswell as locked wheel braking.
Snow tires, studded tires 1
Tires for winter use:
•
Owners who live in or regularly commute through areas with sustained periods ofsnow or icy driving conditions arestrongly advised to fit suitable winter tires to help retain the highest degree of trac-tion.
• It is important to install winter tires on allfour wheels to help retain traction duringcornering, braking, and accelerating. Fail-ure to do so could reduce traction to anunsafe level or adversely affect handling.
• Do not mix tires of different design as thiscould also negatively affect overall tireroad grip.
• Winter tires wear more quickly on dryroads in warm weather. They should beremoved when the winter driving seasonhas ended.
• Studded tires should be run-in 300 – 600 miles (500 – 1000 km) during whichthe vehicle should be driven as smoothlyas possible to give the studs the opportu-nity to seat properly in the tires. The tiresshould have the same rotational directionthroughout their entire lifetime.
NOTE
Please consult state or provincial regula- tions restricting the use of studded wintertires before installing such tires.

}}
* Option/accessory, for more information, see Introduction.327
Tire sealing system–temporarily repairing a flat tire
Temporarily repairing a flat tire is done in two stages:
• Stage 1:
The hole is sealed by pumping
sealing compound into the tire. The car is then driven a short distance to distributethe sealing compound in the tire.
NOTE
Do not remove any foreign objects (nails, etc.) from the tire before using the sealingsystem.
• Stage 2:
The tire’s inflation pressure is
checked and adjusted if necessary.
WARNING
• Never leave the tire sealing system unattended when it is operating.
• Keep the tire sealing system awayfrom children.
• Be sure the vehicle is parked safely offthe road and away from moving traffic.
• Apply the parking brake.
Stage 1: Sealing the hole1. Peel off the speed limit sticker and affix it
to the steering wheel hub where it will be clearly visible to the driver.
2. Ensure that the on/off switch is in posi- tion 0 (the 0 side of the switch should be
pressed down).
WARNING
Contact with the sealing compound may cause skin irritation. If contact occurs,wash the affected area immediately withsoap and water.
3. 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 isscrewed into the holder.
4. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep it securely in place and help preventsealing compound leakage. Once in place,the bottle cannot be unscrewed. This mustbe done by a trained and qualified Volvoservice technician.
5. Remove the valve cap from the tire’sinflation valve and screw the tire sealing system’s hose connector onto the valveas tightly as possible by hand.

Inflating tires
The 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 position0 (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 inflation valve and screw the hose con- nector onto the valve as tightly as possi-ble 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 toavoid battery drain. Therefore, be surethe vehicle is parked in a well ventilatedplace, or outdoors, before using thesystem. The parking brake should besecurely applied and the gear selectorshould be in the
P (park) position.
• Children should never be left unatten-ded in the vehicle when the engine isrunning.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to get a clear reading from the pressuregauge.
8. Refer to the tire inflation table in this chapter for the correct inflation pressure.If the tire needs to be inflated, start thetire sealing system’s compressor (pressthe on/off switch to position I). If neces-sary, release air from the tire by turningthe air release knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
9. Turn off the compressor (press the on/off switch to position 0) when the correct
inflation pressure has been reached.
10. Unscrew the hose from the tire’s inflation valve and reinstall the valve cap.
CAUTION
•After pumping the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
11. Disconnect the electrical wire from the
12-volt socket.

Location of jack and tools
Spare wheelThe spare wheel is only intended for tempo- rary use. Replace it with a normal wheel assoon as possible. The car's handling may bealtered by the use of the spare wheel. Thecorrect tire pressure for the spare wheel isstated in the tire pressure table on page 316and in the tire inflation placard on the driver'sside door jamb at the rear of the driver's dooropening.
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.
CAUTION
The vehicle must never be driven with more than one temporary spare wheel.
The spare wheel is located in the spare wheel well with the rim side down. There are twofoam blocks, one under the spare wheel andone over/inside. The upper one contains alltools. The same bolt runs through to secure the spare wheel and the foam blocks.
Taking out the spare wheel1. Open the floor hatch.
2. Undo the retaining bolt.
3. Lift out the foam block.
4. Lift out the spare wheel.The other two blocks can remain in the spare wheel well.
After useThe foam block and spare wheel must be replaced in the reverse order. Note the arrowon the upper foam block. It should point for-ward.
NOTE
If the floor hatch is not completely closed, the private locking feature (see page 67)will not function.
Changing a wheel1. Apply the parking brake and put the gear
selector in P.
2. Take out the jack*, lug wrench*, the tow- ing eyelet and the wheel cover removal tool* stowed under the floor of the cargoarea.
3. Remove the wheel cover (where applica- ble) using the removal tool or remove thewheel cover by hand.
4. Block the wheels that are on the ground with wooden blocks or large stones.

WARNING
•The jack must correctly engage the jack attachment.
• Be sure the jack is on a firm, level,non-slippery surface.
• Never allow any part of your body tobe extended under a vehicle suppor-ted by a jack.
• Use the jack intended for the vehiclewhen changing a tire. For any otherjob, use stands to support the vehicle.
• Apply the parking brake and put thegear selector in the Park (
P) position.
• Block the wheels standing on theground, use rigid wooden blocks orlarge stones.
• The jack should be kept well-greasedand clean, and should not be dam-aged.
• No objects should be placed betweenthe base of jack and the ground, orbetween the jack and the attachmentbar on the vehicle.
NOTE
The jack provided with your vehicle is intended to be used only in temporary sit-uations such as changing wheels in theevent of a flat tire. Only the jack that camewith your particular model should be usedto lift the vehicle. If the vehicle needs to belifted more frequently or for a prolongedperiod, using a garage jack or hoist is rec-ommended. Always follow this device’sinstructions for use.
Re-installing the wheel1. Clean the contact surfaces on the wheel
and hub.
2. Lift the wheel and place it on the hub.
Tighten the wheel nuts 3. Install the wheel nuts and tighten hand-
tight. Using the lug wrench, tighten cross- wise until all nuts are snug.
4. Lower the vehicle to the ground and alter- nately tighten the bolts crosswise to103 ft. lbs. (140 Nm).

Coolant
Location of the coolant reservoir
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo servicetechnician. See page 389 for information on cooling sys- tem capacities.
CAUTION
• If necessary, top up the cooling sys- tem with Volvo Genuine Coolant/Anti-freeze only (a 50/50 mix of water andantifreeze).
• Different types of antifreeze/coolantmay not be mixed.
• If the cooling system is drained, itshould be flushed with clean water orpremixed anti-freeze before it is refilledwith the correct mixture of water/anti-freeze.
• The cooling system must always bekept filled to the correct level, and thelevel must be between the
MIN and
MAX marks. If it is not kept filled, there
can be high local temperatures in theengine which could result in damage.Check coolant regularly!
• Do not top up with water only. Thisreduces the rust-protective and anti-freeze qualities of the coolant and hasa lower boiling point. It can also causedamage to the cooling system if itshould freeze.
• Do not use chlorinated tap water in thevehicle's cooling system.
WARNING
• Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.
Brake fluid
Location of the brake fluid reservoir
Checking the levelThe fluid reservoir is concealed under the round cover at the rear of the engine com-partment. The round cover must be removedfirst before the reservoir cap can beaccessed.
