NOTE
Volvo recommends only using Volvo origi- nal accessories. Follow the instructionssupplied with the product.
CAUTION
Never use towbar adapters or towbar extenders
Only use ball mount for towing. Do notmount accessories directly on the ballmount. Use accessories designed tobe mounted in the towbar's squarebracket. Do not use accessoriesdesigned to be secured around the ballmount.
Loading the bicycle holderThe greater the distance between the load and the bicycle holder, the greater the load on thehitch and on the vehicle. Keep the following points in mind: Mount the heaviest bicycle closest to the vehicle.
If possible, mount the bicycles symmetri-cally, as close as possible to the center ofthe vehicle.
Remove loose objects from the bicycle,such as baskets, batteries or child seats.This will help reduce the load on the hitchand the bicycle holder.
Do not place a cover over the bicycle asthis could lead to increased load on thehitch.

Driving with a trailer
There are a number of things to consider when towing a trailer, such as the towbar, thetrailer and how the load is distributed in thetrailer.
Load-carrying capacity is determined by the vehicle's curb weight. The total weight of allpassengers and any installed accessories, e.g.towbar, reduces the vehicle's load-carryingcapacity by the corresponding amount.
Towbars used on the vehicle must beapproved for the applicable use.
Distribute the load on the trailer so thatthe weight on the towbar complies withthe specified maximum towball weight.The tongue weight is calculated as part ofthe vehicle's payload.
Increase the tire pressure to the recom-mended pressure for a full load.
The engine is subjected to more load thanusual when towing a trailer.
Towing a trailer affects the vehicle's han-dling, durability and driving economy.
Do not drive with a heavy trailer when thevehicle is very new. Wait until the mileagehas reached at least 1000 km (620 miles).
On long and steep downgrades, the vehi-cle's brakes are subjected to much moreload than usual. When manually shifting, downshift and adapt speed accordingly.
Follow applicable regulations regarding permitted speed and weight.
Drive slowly when towing a trailer up along and steep incline.
The maximum trailer weights given onlyapply to altitudes up to 1000 meters(3280 feet) above sea level. At higher alti-tudes, engine power (and thus the vehi-cle's climbing ability) is decreased due tothe reduced air density, and the maximumtrailer weight must therefore be reduced.The weight of the vehicle and trailer mustbe decreased by 10% for each additional1000 m (3280 feet) or part thereof.
Avoid driving with a trailer on inclines ofmore than 12%.
Avoid overloading and other incorrect use.
The trailer's brakes must be balanced withthe vehicle's brakes to help ensure safestops (follow applicable local regulations).
NOTE
To facilitate towing a trailer in a vehicle equipped with pneumatic suspension
*,
select: the
Suspension ControlDynamic setting in Individual drive mode.
CAUTION
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 chains or wire must be correctlyfastened to the attachment points pro-vided in the trailer hitch on the vehicle.The safety chain or wire must never befastened to or wound around the tow-ing ball.
NOTE
The optional detachable trailer hitch may not be available in all markets or on allmodels. Consult your Volvo retailer.

Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Never attempt to tow a Twin Engine vehicle behind another vehicle as this could damagethe electric motor. The vehicle must instead belifted onto a tow truck and transported with allfour wheels on the bed or lifting platform ofthe truck (no wheels may touch the road).
Towing another vehicleTowing another vehicle requires a lot of power - use the Constant AWD drive mode. This
helps charge the hybrid battery and improve the vehicle's driving and roadholding characte-ristics. Before towing another vehicle, check applica- ble speed limit regulations.
Jump startingNever attempt to tow the vehicle to start theengine, as this could damage the electricmotor. Use an auxiliary battery if the start bat-tery's charge level is so low that the enginecannot be started.
CAUTION
Attempts to tow-start the vehicle could cause damage to the electrical drive motorand three-way catalytic converter.

Removing a wheel Wheel changes must always be carried out correctly. The following instructions showhow to remove a wheel and what is impor-tant to keep in mind.
CAUTION
When not in use, the jack
* should be
kept in its storage compartment under the cargo compartment floor.
The jack provided with your vehicle isintended to be used only in temporarysituations such as changing wheels inthe event of a flat tire. Only the jackthat came with your particular modelshould be used to lift the vehicle. If thevehicle needs to be lifted more fre-quently or for a prolonged period, usinga garage jack or hoist is recommended.Always follow this device's instructionsfor use.
WARNING
Apply the parking brake and put the gear selector in the Park (
P) position.
Block the wheels standing on theground, use rigid wooden blocks orlarge stones.
Check that the jack is not damaged,the threads are properly lubricated andit is free from dirt.
Be sure the jack is on a firm, level, non-slippery surface and that it is uprightand not leaning.
The jack must correctly engage in thejack attachment.
No objects should be placed betweenthe base of the jack and the ground, orbetween the jack and the attachmentbar on the vehicle.
Never let anyone remain in the vehiclewhen it is raised on a jack.
If a tire must be changed near passingtraffic, make sure all passengers moveto a safe location.
Use a jack intended for the vehiclewhen changing a tire. For any otherjob, use stands to support the vehicle.
Never crawl under or allow any part ofyour body to be extended under a vehi-cle supported by a jack. 1. Turn on the vehicle's hazard warning
flashers if a wheel change must be per-formed in an area with traffic.
2. Apply the parking brake and put the gear selector in P, or first gear if the vehicle has
a manual transmission. For vehicles with
Leveling Control* : If the
vehicle is equipped with pneumatic sus- pension, this must be switched off before the vehicle is lifted with the jack *.
3. Take out the jack *, lug wrench * and tool for
removing the plastic covers, which are stowed in the foam block.

2. Peel off the speed limit sticker from the
side of the compressor. Affix the decal to a clearly visible location on the windshieldto remind the driver not to exceed thisspeed limit. Do not drive faster than80 km/h (50 mph) while using a tire thathas been temporarily repaired with the tiresealing system.
3. Make sure the switch is in the 0 (Off)
position and take out the electric cableand the hose.
4. Unscrew the orange cover on the com- pressor and unscrew the cap on the seal-ing compound bottle.
5. Screw the bottle onto the bottle holder as far as possible. The bottle and the bottle holder are equip- ped with catches to help prevent the seal-ing compound from leaking. Once the bot-tle is screwed into place into the bottleholder, it cannot be unscrewed. The bottle can only be removed by a workshop 18
.
WARNING
Do not unscrew the bottle. It is equipped with a catch to prevent leakage. 6. Unscrew the tire's valve cap and screw
the hose's valve connector as far as possi- ble onto the valve. Be sure the air release valve on the com- pressor's hose is completely closed.
7. Connect the electrical cable to the nearest 12 V outlet and start the vehicle.
NOTE
Make sure that none of the vehicle's other 12 V sockets are used while the compres-sor is running.
WARNING
Never leave children unattended in the vehicle while the engine is running.
WARNING
Inhaling exhaust fumes could lead to seri- ous injury. Never leave the engine runningin an enclosed space or a space withoutsufficient ventilation. 8. Start the compressor by moving the
switch to the I (On) position.
WARNING
Never stand next to a tire being inflated with the compressor. If cracks, bulges, etc.form on the tire, switch off the compressorimmediately. The vehicle should not bedriven. Call roadside assistance to have thevehicle towed to a workshop for inspec-tion/replacement of the tire. Volvo recom-mends an authorized workshop.
NOTE
When the compressor first starts, air pres- sure may temporarily increase up to 6 bar(88 psi) but should decrease again afterapproximately 30 seconds.
9. Inflate the tire for 7 minutes.
CAUTION
To help avoid overheating, the compressor should never be used for more than10 minutes at a time.

57210. Switch off the compressor and check the
inflation pressure using the air pressure gauge. The inflation pressure should bebetween 1.8 bar (22 psi) and 3.5 bar(51 psi). If the inflation pressure is toohigh, use the air release valve to releaseair.
WARNING
If pressure falls below 1.8 bar (22 psi), the hole in the tire may be too large. The vehi-cle should not be driven. Call roadsideassistance to have the vehicle towed to aworkshop for inspection/replacement ofthe tire. Volvo recommends an authorizedworkshop.
11. Switch off the compressor and remove the electrical cable.
12. Unscrew the hose from the tire's valve and screw the valve cap back on.
NOTE
After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
13. Put the protective hose cover onto the
hose to help prevent leakage of any resid- ual sealing compound. Return the equip-ment to the cargo compartment.
14. Immediately drive the vehicle at least 3 km (2 miles) at a maximum speed of80 km/h (50 mph) to allow the sealingcompound to seal the tire, and thenrecheck the inflation pressure.
WARNING
During the tire's first revolution, some seal- ing compound may spray out of the punc-ture hole. Before driving away, make surethat no one is near the vehicle who couldbe sprayed with sealing compound. Makesure no one is within 2 meters(7 feet) ofthe vehicle.
15. Rechecking the inflation pressure Connect the hose to the tire's valve and screw the hose connector onto the valveas far as possible. The compressor mustbe switched off. 16. Check the inflation pressure on the air
pressure gauge.
If the pressure is under 1.3 bar (19 psi),the tire is not sufficiently sealed. Thevehicle should not be driven. Call road-side assistance to have the vehicletowed.
If the inflation pressure is higher than1.3 bar (19 psi), the tire must be inflatedto the inflation pressure specified onthe tire pressure decal on the driver'sside door pillar (1 bar = 100 kPa =14.5 psi). If the inflation pressure is toohigh, use the air release valve to releaseair.
WARNING
Check inflation pressure regularly.
Volvo recommends driving to the nearest authorized Volvo workshop to have the tirereplaced/repaired. Inform the workshop thatthe tire contains sealing compound. The sealing compound bottle and the hose must be replaced after use. Volvo recom-mends contacting an authorized Volvo work-shop for replacement.

Determining the vehicle's permitted weight
Properly loading your vehicle will provide maximum return of vehicle design perform-ance.
Weight designationsBefore loading your vehicle, familiarize your- self with the following terms for determiningyour vehicle's weight ratings, with or without atrailer, from the vehicle's Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label, and the vehicle's tire informa-tion placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does notinclude passengers, cargo, or optional equip-ment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing,towbar weight is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (front or rear). Thesenumbers are shown on the Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label. The total load on each axlemust never exceed its maximum permissibleweight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passen- gers.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight of occupants and cargo shouldnever exceed XXX kg or XXX lbs." on yourvehicle's placard.
2. Determine the combined weight of the driver and passengers that will be riding inyour vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXXlbs.
4. The resulting figure equals the available amount of cargo and luggage loadcapacity. For example, if the "XXX"amount equals 1400 lbs. and there will befive 150 lb. passengers in your vehicle, theamount of available cargo and luggageload capacity is 650 lbs. (1400 - 750 (5 ×150) = 650 lbs.)
5. Determine the combined weight of lug- gage and cargo being loaded on the vehi-cle. That weight may not safely exceed theavailable cargo and luggage load capacitycalculated in Step 4.
