Hill Descent Control (HDC) – operation
Function
•HDC can be switched on and off with the button in the center console. An indicatorlight in the button illuminates when HDC isactivated.
• The indicator light
in the instrument
panel illuminates and a message is displayed when the system is controlling the vehicle'sspeed.
• HDC only functions when
first or reverse
gears are selected (
1 will be shown in the
instrument panel display when first gear is selected).
NOTE
HDC cannot be activated if the gear selector is the D position.
Using HDCHDC allows the car to roll forward at a maximum speed of 6 mph (10 km/h), and 4 mph (7 km/h)in reverse. However, the accelerator pedal can beused to select any speed that is possible in firstor reverse gears. When the accelerator pedal isreleased, speed is quickly reduced again to6 mph (10 km/h) or 4 mph (7 km/h), dependingon the gear selected, regardless of the hill's gra-dient. It is not necessary to apply the brakes.
• The brake lights illuminate automaticallywhen HDC is controlling the vehicle's speed.
• The driver can slow or stop the vehicle at anytime by applying the brakes.
HDC is deactivated when:
• The button on the center console is pressed
• A gear higher than first gear is selected
• D
is selected on vehicles with an automatic
transmission
HDC can be deactivated at any time. If this isdone while driving down a steep hill, the system'sbraking effect will decrease gradually.
NOTE
Engine response to pressure on the accelera- tor pedal may be slightly slower than normalwhen HDC is activated.

• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy.
• It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.
NOTE
• When parking the vehicle with a trailer on a hill, apply the parking brake before put- ting the gear selector in
P. Always follow
the trailer manufacturer's recommenda- tions for wheel chocking.
• When starting on a hill, put the gear selector in
D before releasing the parking
brake.
• If you use the manual (Geartronic) shift positions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
• The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
• Avoid driving with a trailer on inclines ofmore than 15%.
CAUTION
The maximum trailer weights listed are only applicable for altitudes up to 3,280 ft(1000 m) above sea level. With increasingaltitude the engine power and therefore thecar's climbing ability are impaired because ofthe reduced air density, so the maximumtrailer weight has to be reduced accordingly.The weight of the vehicle and trailer must bereduced by 10% for every further 3,280 ft(1,000 m) (or part thereof). When towing5,000 lbs (2,250 kg) hill inclination is restric-ted to 14%.
