WARNING
The vehicle must never be driven with more than one "Temporary Spare" tiremounted.
Driving with a spare wheel may alterthe driving characteristics of the vehi-cle. Replace the spare wheel with anormal wheel as soon as possible.
The spare wheel is smaller than thenormal wheel, which affects the vehi-cle's ground clearance. Watch for highcurbs and do not wash the vehicle inan automatic car wash when a sparewheel is mounted.
Follow the manufacturer's recom-mended tire inflation pressure for thespare wheel.
On all-wheel drive vehicles, the driveon the rear axle can be disconnected.
If the spare wheel is mounted on thefront axle, snow chains must not beused.
The spare wheel must not be repaired.
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 vehicle's transmis-sion.

Cargo compartment
The vehicle has a flexible cargo compartment that makes it possible to carry and securelarge objects.
The cargo compartment capacity can be con- siderably increased by folding down the back- rests in the second and third rows * of seats.
To make loading and unloading easier, the rear section of the vehicle can be raised and low- ered using the level control function *. Use the
load anchoring eyelets or grocery bag holders to help secure objects in place, and the retractable cargo compartment cover * to help
conceal objects in the cargo compartment. If the vehicle is equipped with a temporary spare tire, this is secured to the cargo com-partment floor under the cover. The towingeyelet and tire sealing system are locatedunder the cargo compartment floor.

Loading recommendations
There are a number of things that are impor- tant to consider when carrying loads in or onthe vehicle.
Load-carrying capacity is determined by the vehicle's curb weight. The total weight of allpassengers and any installed accessoriesreduces the vehicle's load-carrying capacity bythe corresponding amount.
WARNING
The vehicle's driving characteristics change depending on the weight and position ofthe load.
Loading the cargo compartment/trunkKeep the following in mind when loading:
Position objects so they are pressing against the rear seat backrests.
Heavy objects should be positioned as lowas possible. Avoid placing heavy objectson folded-down seat backrests.
Cover sharp corners with a soft cloth orsimilar to help prevent damage to theupholstery.
Use the load anchoring eyelets and ten-sioning straps or similar to secure allobjects.
WARNING
In a head-on collision at a speed of 50 km/h (30 mph), an unsecured objectweighing 20 kg (44 pounds) can reach aprojectile weight equivalent to 1000 kg(2200 pounds).
WARNING
If objects are loaded higher than the upper edge of the side windows, leave a 10 cm(4 in.) space between the objects and thewindow. Objects placed closer to thiscould impede the function of the inflatablecurtain concealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift during heavy braking and injure peo-ple in the vehicle. Cover sharp edges and sharp corners with something soft. Turn off the engine and apply the parking brake when loading/unloading longobjects. Otherwise, it is possible for theload to reach the gear lever or gear selectorand move it to a drive position – whichcould cause the vehicle to begin rolling.
Extra cargo space
The rear seat backrests can be folded down to increase cargo space in the cargo compart- ment/trunk and simplify loading. If the rearseat backrests are folded down, make surethat no objects loaded into the vehicle preventthe WHIPS system for the front seats fromfunctioning correctly.
Raising/lowering the rear end of the
vehicle *
The rear end of the vehicle can be lowered orraised for easier loading into the cargo com-partment/trunk or to facilitate attaching a trailer*.
The controls for raising/lowering are located at the rear edge of the right side panel in thecargo compartment/trunk.
Controls for raising/lowering the rear end of the vehi- cle.
The controls consist of two buttons ‒
one but-
ton for lowering and one button for raising the

586 rear end. Press and hold the relevant button until the desired 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 height when the vehicle begins driving.
NOTE
It is not possible to adjust the height of the vehicle's rear when one or more of thedoors or the hood is open. This does notapply to the tailgate.
WARNING
Make sure that no people, animals or objects are found under the vehicle when itis lowered. This could endanger life andcause damage to the vehicle or objects.

Roof loads and load carriers
Volvo-developed load carriers are recom- mended for carrying loads on the roof of thevehicle.
Volvo load carriers are specially designed to help prevent damage to your vehicle and helpensure maximum safety while driving. Volvoload carriers are available from authorizedVolvo retailers. Carefully follow the installation instructions provided with the load carriers. Distribute the load evenly throughout the load carriers. Place heavier cargo at thebottom of the load.
Check periodically to ensure that the loadcarriers and load are properly secured.Secure the load firmly using tie straps orsimilar.
If the load is longer than the vehicle, suchas a canoe or kayak, attach the towingeyelet in its front outlet and secure the tiestraps in it.
The vehicle's wind resistance and fuelconsumption increase with the size of theload.
Drive smoothly. Avoid rapid acceleration,hard braking and fast cornering.
WARNING
The vehicle's center of gravity and driving characteristics are altered by roof loads. Follow the vehicle's specifications regar- ding weights and maximum permittedload.

Installing and removing the steel cargo grid*
The steel cargo grid prevents loads or pets in the cargo compartment from being thrownforward into the passenger compartmentduring hard braking.
For safety reasons, the steel grid must always be installed and secured correctly.
WARNING
Under no circumstances may a person be in the cargo compartment when the vehi-cle is moving. Heavy braking or a collisioncould lead to serious injury.
The steel grid consists of the grid itself and two separate mounting brackets. Each of the mounting brackets has a screw cover and twoplastic sleeves for the grid.
WARNING
The steel cargo grid may only be used in the rear position described here. The ceil-ing attachment points behind the frontseats are not intended to anchor the steelgrid.
WARNING
For safety reasons, the third-row seats
4
must be folded down when the steel cargo grid is mounted in the vehicle.
CAUTION
The steel cargo grid and the cargo com- partment cover cannot be mounted at thesame time.
Installation1. Fold down the rear seats and lift in the steel grid through one of the rear doors or the tailgate. The curved (convex) side ofthe grid should face toward the cargocompartment and the hooks on each sideof the grid should face upward. Themounting brackets and plastic sleeves arenot needed in this step. 2.
Press one of the grid's hooks into the larger hole in the ceiling attachment point(1). Grasp the grid near the hook and pull/push it into the smaller hole (2).
> The hook is now secured in the attach-
ment point.
