Low Speed Control
*
The low-speed function, Low Speed Control (LSC), facilitates and improves control and trac-tion on rough roads and slippery surfaces, e.g.when towing a trailer on grass or up boat ramps. In vehicles equipped with drive mode control *,
the function is included in the Off Road drive mode.
Low Speed Control is designed for driving on rough roads and when towing trailers at lowspeeds, up to approximately 40 km/h (25 mph). When driving at low speeds, LSC prioritizes low gears and all-wheel drive to help avoid wheel spinand improve traction on all wheels. The accelera-tor pedal will be less responsive to improve trac-tion and speed control at low speeds. The function is activated together with Hill Descent Control (HDC), which makes it possibleto control speed going down steep hills using theaccelerator pedal and reduces the need to usethe brake pedal. The system makes it possible tomaintain a low and uniform speed when drivingdown steep hills.

450 •
Follow applicable regulations regarding per- mitted speed and weight.
• Drive slowly when towing a trailer up a longand steep incline.
• The maximum trailer weights given only applyto altitudes up to 1000 meters (3280 feet)above sea level. At higher altitudes, enginepower (and thus the vehicle's climbing ability)is decreased due to the reduced air density,and the maximum trailer weight must there-fore be reduced. The weight of the vehicleand trailer must be decreased by 10% foreach additional 1000 m (3280 feet) or partthereof.
• Avoid driving with a trailer on inclines of morethan 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).
CAUTION
•Bumper-attached trailer hitches must not be used on Volvos, nor should safetychains be attached to the bumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulic brakesystem directly to the vehicle brake sys-tem, nor a trailer's lighting system directlyto the vehicle lighting system. Consultyour nearest authorized Volvo retailer forcorrect installation.
• When towing a trailer, the trailer's safetychains or wire must be correctly fastenedto the attachment points provided in thetrailer hitch on the vehicle. The safetychain or wire must never be fastened toor wound around the towing ball.
NOTE
The optional detachable trailer hitch may not be available in all markets or on all models.Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer, driving at high altitudes and fuel quality arefactors that significantly increase a vehicle'sfuel consumption.
Trailer weights
WARNING
Please adhere to the recommendations provi- ded for trailer weight. If the recommendationsare not followed, the vehicle and trailer maybe difficult to control during evasive maneu-vers and braking.
NOTE
The specified maximum trailer weights are those permitted by Volvo. National vehicleregulations may set additional restrictions ontrailer weight and speed. The trailer hitchesmay be certified for higher towing weightsthan the vehicle is permitted to tow.
Self-leveling suspension
*The vehicle's self-leveling system attempts to keep the vehicle at a constant level, regardless ofload (up to the maximum permitted weight).When the vehicle is stationary, the rear end of thevehicle will be slightly lowered, which is normal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of overheat-ing when driving with a trailer. If overheating ofthe engine and drive system is detected, a warn-ing symbol will illuminate in the instrument panelalong with a message.

4. Screw in the towing eyelet until it reaches its
stop. Fasten the eyelet securing by, for exam- ple, inserting a lug wrench * through it and
using this as a lever.
CAUTION
It is important that the towing eye is screwed in securely as far as possible.
Removing the towing eyelet:
–After use, unscrew the towing eyelet and return it to its storage location. Replace the cover on the bumper.
In certain conditions, the towing eyelet may be used to pull the vehicle onto a flatbed tow truck.The vehicle's position and ground clearancedetermines if this is possible. If the incline of the tow truck is too steep or if the ground clearance under the vehicle is insufficient, attempting to pull it up using the towing eyeletmay result in damage. If necessary, lift the vehicle using the tow truck's lifting device instead of using the towing eyelet.
WARNING
No person or object should be behind the tow truck when the vehicle is lifted onto the bedof the truck.
CAUTION
The towing eyelet is only intended for towing on roads, and must
not be used to pull vehi-
cles from ditches or any similar purpose involving severe strain. Call a tow truck forprofessional assistance.

The vehicle's location and ground clearance determine if it can be lifted onto a tow truck. Ifthe incline of the tow truck is too steep or if theground clearance under the vehicle is insufficient,attempting to pull it up may result in damage. Inthis case, the vehicle should only be lifted withthe tow truck's lifting equipment.
WARNING
No person or object should be behind the tow truck when the vehicle is lifted onto the bedof the truck.

WHEELS AND TIRES

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.565
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.

MAINTENANCE AND SERVICE
626
Cleaning rims The vehicle should be washed as soon as it becomes dirty. This makes the vehicle easier toclean because dirt does not attach as strongly. Italso reduces the risk of scratches and keeps thevehicle looking new. Wash the vehicle in a carwash or garage with an oil separator. Use a carwashing detergent.
RimsOnly use rim cleaning products recommended by Volvo. Strong rim cleaning agents could damage the surface and stain the chromed aluminum rims.

Corrosion protection
Your vehicle is constructed with effective protec- tion against corrosion.
Corrosion protection for the body consists of modern metallic protective coatings on the sheetmetal, a high-quality painting process, corrosion-protected and minimized metal overlap, andshielding plastic components, abrasion protectionand supplemental rust inhibitor in exposed areas.In the chassis, exposed components of the wheelsuspension are made of corrosion-resistant castaluminum.
Inspection and maintenanceThe corrosion protection does not normallyrequire maintenance, but keeping the vehicleclean is always a good way to further reduce therisk of corrosion. The use of strong alkaline oracidic cleaning fluids should always be avoidedon shiny body components. Any stone chips inthe paint should be touched up as soon as theyare discovered.
