434 pedal. When the accelerator pedal is released, the vehicle will return to very low speedregardless of how steep the hill is and withoutthe brakes needing to be applied. The brakelights will illuminate when the function is acti-vated. The driver can brake to stop or slow the vehi- cle at any time by depressing the brake pedal. HDC is activated along with Low Speed Con- trol (LSC
18
), which facilitates and improves
traction and control on rough and slippery sur- faces. The system is intended to be used atlow speeds, up to approximately 40 km/h (25mph).
To keep in mind when using HDC
If the function is switched off while drivingon a steep downhill gradient, brakingeffect will be 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 engineresponse will 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 atlower speeds if so desired.

Slippery driving conditionsTo help optimize traction and roadholding, Volvo recommends using snow tires on allwheels whenever there is a risk of snow or iceon the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under controlled conditions to learn how the vehiclereacts.

Driving through standing water
It may be necessary to drive the vehicle through standing water e.g. deep puddles orflooding on the road. This must be done withgreat caution.
The vehicle can be driven through water up to a depth of 30 cm (11 in) at no more than walk-ing speed. Be particularly careful when drivingthrough flowing water. When driving through standing water, drive slowly and do not stop the vehicle. When youhave passed the water, press lightly on thebrake pedal and check that the brakes arefunctioning properly. Water, mud, slush, etc.can make the brake linings slippery, resultingin delayed braking effect. If the vehicle is equipped with contacts for an electric heater or trailer coupling, cleanthese after driving in water or mud.
Do not allow the vehicle to stand in waterup to the sills any longer than absolutelynecessary. This could result in electricalmalfunctions.
CAUTION
Engine damage could occur if water enters the air cleaner.
If water enters the transmission, thelubricating ability of the oils is reducedand the service life of these systems isshortened.
Damage to any component, engine,transmission, turbocharger, differentialor its internal components caused byflooding, vapor lock or insufficient oil isnot covered under warranty.
If the engine stalls while the vehicle isin water, do not attempt to restart it.Have the vehicle towed out of thewater to a workshop. An authorizedVolvo workshop is recommended. Riskof engine failure.
CAUTION
Because it can be difficult to determine the water depth, Volvo recommends not driv-ing through standing or running water. Thedriver is always responsible for operatingthe vehicle in a safe manner and adheringto all applicable laws and regulations.

Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle if youdetect engine misfire, noticeable loss ofpower or other unusual operating condi-tions, such as engine overheating or back-firing. A properly tuned engine will helpavoid malfunctions that could damage thethree-way catalytic converter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, whichcan come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cata-lytic converter or exhaust system over-heating.
Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehicle maybe illegal and can cause three-way cata-lytic converter or exhaust system over-heating. This includes: altering fuel injec- tion settings or components, alteringemission system components or locationor removing components, and/or repeateduse of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readings are fed into a control module that continuouslymonitors engine functions and controls fuelinjection. The ratio of fuel to air into the engineis continuously adjusted for efficient combus-tion to help reduce harmful emissions.

Overheating of engine and transmission
In certain driving conditions, such as driving in mountainous areas or hot weather, there isa risk of the engine or transmission overheat-ing, especially when carrying heavy loads.
Engine power may be temporarily limited.
Remove any auxiliary lights mounted in front of the grille when driving in hotweather.
If the temperature in the engine's coolingsystem becomes too high, a warning sym-bol will appear in the instrument panel along with the message

Battery drain
The electrical functions in the vehicle drain the battery to varying degrees. Avoid usingignition mode II when the engine is switched
off. Use ignition mode I instead, as this uses
less electrical current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical currentwhen the engine is turned off. Examples ofsuch functions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is shown in the driver display. The vehicle'senergy-saving function will then turn off orreduce certain functions, such as the blowerand/or the audio system.
–To charge the battery, start the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

Driving with a trailer
There are a number of things to consider when towing a trailer, such as the towbar, thetrailer and how the load is distributed in thetrailer.
Load-carrying capacity is determined by the vehicle's curb weight. The total weight of allpassengers and any installed accessories, e.g.towbar, reduces the vehicle's load-carryingcapacity by the corresponding amount.
Towbars used on the vehicle must beapproved for the applicable use.
Distribute the load on the trailer so thatthe weight on the towbar complies withthe specified maximum towball weight.The tongue weight is calculated as part ofthe vehicle's payload.
Increase the tire pressure to the recom-mended pressure for a full load.
The engine is subjected to more load thanusual when towing a trailer.
Towing a trailer affects the vehicle's han-dling, durability and driving economy.
Do not drive with a heavy trailer when thevehicle is very new. Wait until the mileagehas reached at least 1000 km (620 miles).
On long and steep downgrades, the vehi-cle's brakes are subjected to much moreload than usual. When manually shifting, downshift and adapt speed accordingly.
Follow applicable regulations regarding permitted speed and weight.
Drive slowly when towing a trailer up along and steep incline.
The maximum trailer weights given onlyapply to altitudes up to 1000 meters(3280 feet) above sea level. At higher alti-tudes, engine power (and thus the vehi-cle's climbing ability) is decreased due tothe reduced air density, and the maximumtrailer weight must therefore be reduced.The weight of the vehicle and trailer mustbe decreased by 10% for each additional1000 m (3280 feet) or part thereof.
Avoid driving with a trailer on inclines ofmore than 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).
