Before mounting the bicycle on the bicycle holder, keep in mind that:
The maximum weight for the bicycleholder including bicycles is 130 lbs/60 kg.For example: holder 40 lbs + bicycle 30lbs + bicycle 30 lbs = 100 lbs total > OK
Do not mount more than two bicycles
The center of gravity should not exceed thedimensions:
1. 613 mm (24 1/7 ")

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.

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.
Tool for removing the plastic covers on the wheel bolts.
4. Place chocks in front of and behind the wheels that are still on the ground. For example, use heavy wooden blocks orlarge stones.
