STARTING AND DRIVING
* Option/accessory.437
Hill Descent Control *
The function for assisting when driving downhill, Hill Descent Control (HDC), is a low-speedfunction with increased engine braking. Thefunction makes it possible to increase ordecrease the vehicle's speed on steep downhillgradients by only using the accelerator pedal,without applying the brakes. In vehicles equipped with drive mode control *,
the function is included in the Off Road drive mode.
HDC is designed for driving on rough roads at low speeds and downhill gradients with slipperyor otherwise difficult road surfaces. The driverdoes not need to use the brake pedal but caninstead focus on steering.
WARNING
HDC is only intended to be a supplementary braking aid and it does not function in all sit-uations. The driver is always ultimately responsible for operating the vehicle in a safe manner.
FunctionHill Descent Control allows the vehicle to move forward or backward at very low speeds assistedby the brake system. The driver can increase thespeed by pressing the accelerator pedal. Whenthe accelerator pedal is released, the vehicle will return to very low speed regardless of how steepthe hill is and without the brakes needing to beapplied. The brake lights will illuminate when thefunction is activated. The driver can brake to stop or slow the vehicle at any time by depressing the brake pedal. HDC is activated along with Low Speed Control (LSC), which facilitates and improves traction andcontrol on rough and slippery surfaces. The sys-tem is intended to be used at low speeds, up toapproximately 40 km/h (25 mph).
To keep in mind when using HDC
•
If the function is switched off while driving ona steep downhill gradient, braking effect willbe gradually reduced.
• HDC can be used in gear positions
D and R,
and in manual gears 1 or 2.
• It is not possible to manually shift to thirdgear or higher when HDC is active.
NOTE
When LSC with HDC is activated, the feel of the accelerator pedal and engine responsewill change.
NOTE
This drive mode is not designed to be used for normal street driving.
NOTE
The function is deactivated when driving at high speeds and must be reactivated at lowerspeeds if so desired.

Overheating of engine andtransmission
In demanding driving conditions, such as driving in mountainous areas or hot weather, there is arisk of the engine or transmission overheating,especially when carrying heavy loads.
• Engine power may be temporarily limited.
• Remove any auxiliary lights mounted in front of the grille when driving in hot weather.
• If the temperature in the engine's coolingsystem becomes too high, a warning symbolwill appear in the instrument panel along with the message
Engine temperature High
temperature Stop safely. Pull over to a
safe location and let the engine idle for a few minutes to cool down.
• If the message
Engine temperature High
temperature Turn off engine or Engine
coolant Level low, turn off engine is dis-
played, stop the vehicle and turn off the engine.
• If the transmission begins to overheat, analternative gear shifting program will beselected. An integrated protective functionwill also be activated, the warning symbol will illuminate and the message
Transmission
warm Reduce speed to lower
temperature or Transmission hot Stop
safely, wait for cooling will be displayed in
the instrument panel. Follow the recommen- dations given by reducing speed or stopping the vehicle safely and letting the engine idle for a few minutes to let the transmissioncool.
• If the vehicle begins to overheat, the air con-ditioning may be temporarily switched off.
• After a prolonged period of driving indemanding conditions, do not turn off theengine immediately after stopping.
NOTE
It is normal for the engine's cooling fan to operate for a short time after the engine isswitched off.

Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Before towing another vehicle, check applicable speed limit regulations.
Preparations and towing
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.
• Do not tow a vehicle with automatictransmission at a speed greater than80 km/h (50 mph) or for a distancegreater than 80 km (50 miles).
WARNING
•
Ignition mode
II must be active – all air-
bags are deactivated in ignition mode I.
• Always have the remote key in the vehicle when it is towed.
WARNING
The brake and steering servos do not work when the engine is off – it takesabout 5 times more pressure on the brakepedal and steering requires much more effortthan normal. 1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.3.
Put the vehicle in ignition mode II – without
pressing the brake pedal, turn the start knob clockwise and hold it there for about4 seconds. Release the knob, which willautomatically return to its original position.
4. Move the gear selector to neutral ( N) and
release the parking brake. If the battery charge level is too low, it may not be possible to release the parking brake.Connect an auxiliary battery to the vehicle ifthe battery is discharged.
> The towing vehicle can now start driving.
5. Keep the towline taut when the towing vehi- cle slows down by applying light pressure to the brake pedal. This will help avoid jarringmovements.
6. Be prepared to apply the brakes to stop the vehicle.
Jump startingDo not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.

MAINTENANCE AND SERVICE
* Option/accessory.
592 If you are experiencing problems with any lights other than light bulbs, contact a workshop
14
. If
there is a problem with an LED 13
light, the entire
lamp unit will normally need to be replaced.
WARNING
The vehicle electrical system must be in igni- tion mode 0 when bulbs are replaced.
CAUTION
Never touch the bulb glass with your bare fin- gers. Grease and oils from your fingers vapor-ize in the heat and will leave a deposit on thereflector, which may damage it.
NOTE
If the error message persists after the defec- tive bulb has been replaced, we recommend avisit to an authorized Volvo workshop.
NOTE
Exterior lighting such as headlights and tail- lights may develop temporary condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.
NOTE
Bulbs for active curve lighting * contain traces
of mercury and should therefore always be submitted to a certified Volvo service techni-cian.

MAINTENANCE AND SERVICE
622•
Wash using a sponge, car washing detergent and plenty of lukewarm water.
• Clean the wiper blades with lukewarm soapsolution or car washing detergent.
• Dry the vehicle using a clean, soft chamois ora squeegee. Try not to let drops of water dryin strong sunlight. This could cause waterdrying stains that may need to be polishedout.
• In areas with heavy industrial emissions,more frequent washing of the vehicle's exte-rior is recommended.
• Tar spots from asphalt may remain even afterwashing. Use a tar remover to remove thesespots after washing the vehicle.
WARNING
Always entrust engine washing to a workshop. If the engine is hot, there is a risk of fire.
CAUTION
Dirty headlights do not work as well. Clean them regularly, e.g. when refueling. Do not use corrosive cleaners. Use water and a non-abrasive sponge.
NOTE
Exterior lighting such as headlights and tail- lights may develop temporary condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.
CAUTION
• Make sure that the panoramic roof and sun shade are closed before washing thevehicle.
• Never use abrasive polishing agents onthe panoramic roof.
• Never use wax on the rubber sealsaround the panoramic roof.
CAUTION
Remember to remove dirt from the drain holes in the doors and sills after washing thevehicle.
