WHEELS AND TIRES
578
Determining the vehicle's permittedweight
Properly loading your vehicle will provide maxi- mum return of vehicle design performance.
Weight designationsBefore loading your vehicle, familiarize yourself with the following terms for determining yourvehicle's weight ratings, with or without a trailer,from the vehicle's Federal/Canadian Motor Vehi-cle Safety Standards (FMVSS/CMVSS) label, andthe vehicle's tire information 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 equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing, tow-bar weight is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be car- ried by a single axle (front or rear). These num-bers are shown on the Federal/Canadian MotorVehicle Safety Standards (FMVSS/CMVSS) label.The total load on each axle must never exceed itsmaximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
Steps for Determining Correct Load Limit
1. Locate the statement "the combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle's plac-ard.
2. Determine the combined weight of the driver and passengers that will be riding in yourvehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and luggage load capacity.For example, if the "XXX" amount equals1400 lbs. and there will be five 150 lb. pas-sengers in your vehicle, the amount of availa-ble cargo and luggage load capacity is 650lbs. (1400 - 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculatedin Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to yourvehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.
WARNING
• Exceeding the permissible axle weight, gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
• Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.587
WARNING
In a head-on collision at a speed of 50 km/h (30 mph), an unsecured object weighing 20kg (44 pounds) can reach a projectile weightequivalent to 1000 kg (2200 pounds).
WARNING
If objects are loaded higher than the upper edge of the side windows, leave a 10 cm (4in.) space between the objects and the win-dow. Objects placed closer to this couldimpede the function of the inflatable curtainconcealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift during heavy braking and injure people in thevehicle. Cover sharp edges and sharp corners with something soft. Turn off the engine and apply the parking brake when loading/unloading long objects.Otherwise, it is possible for the load to reachthe gear lever or gear selector and move it toa drive position – which could cause the vehi-cle to begin rolling.
Extra cargo space
The rear seat backrests can be folded down to increase cargo compartment space and simplifyloading. If the rear seat backrests are folded down, make sure that no objects loaded into thevehicle prevent the WHIPS system for the frontseats from functioning correctly.
Raising/lowering the rear end of the vehicle
*
The rear end of the vehicle can be lowered or raised for easier loading or to facilitate attaching a trailer*.
The controls for raising/lowering are located at the rear edge of the cargo compartment's rightside panel.
Controls for raising/lowering the rear end of the vehicle.
The controls consist of two buttons ‒ one button
for lowering and one button for raising the rear end. Press and hold the relevant button until thedesired height is reached. The rear end of the vehicle cannot be raised higher than its normal height. The rear end will return to the normal heightwhen the vehicle begins driving.
NOTE
It is not possible to adjust the height of the vehicle's rear when one or more of the doorsor the hood is open. This does not apply tothe tailgate.
WARNING
Make sure that no people, animals or objects are found under the vehicle when it is low-ered. This could endanger life and causedamage to the vehicle or objects.

CAUTION
•The maximum trailer weights listed are only applicable for altitudes up to 3280 ft(1,000 m) above sea level. With increas-ing altitude the engine power and there-fore the car's climbing ability are impairedbecause of the reduced air density, sothe maximum trailer weight has to bereduced accordingly. The weight of thecar and trailer must be reduced by 10%for every further 3280 ft (1,000 m) (orpart thereof).
