Auto-hold brakesWith the Auto-hold brake function, the driver can release the brake pedal and the brakes willremain applied, for example, when the vehiclehas stopped at a traffic light or intersection.
When the vehicle stops, the brakes are activated automatically. The function can use either thenormal brakes or the parking brakes to keep thevehicle stationary and works on flat surfaces orhills. When driving off, the brakes will be automat-ically released if the driver's seat belt is buckled.
NOTE
When braking to a stop on an uphill or down- hill gradient, depress the brake pedal withslightly more force than usual before releas-ing to ensure that the vehicle cannot move atall.
The parking brake is activated if: • the vehicle is switched off
• the driver's door is opened
• the driver's seat belt is removed
• the vehicle has been stationary for a pro- longed period of time (5-10 minutes)

Hill Start Assist
The function for assisting when starting the vehi- cle on inclines, Hill Start Assist (HSA), helpsprevent the vehicle from rolling backward whenstarting on an uphill gradient. When backing upa hill, HSA helps prevent the vehicle from rollingforward.
The function retains pressure from the brake pedal in the brake system for several secondsafter the brake pedal has been released. This temporary braking effect is released after a few seconds or when the driver begins driving. Hill Start Assist is available even if the Auto-hold brake function is switched off.

Braking assist after a collision In a collision in which the activation level is reached for the pyrotechnic seat belt tensionersor airbags, or if a collision with a large animal isdetected, the vehicle's brakes will be automati-cally activated. This function is intended to helpprevent or reduce the effects of any subsequentcollision.
After a serious collision, it may no longer be pos- sible to control and steer the vehicle. In order toavoid or mitigate a possible further collision witha vehicle or an object in the vehicle's path, thebrake assist system is activated automatically tohelp stop the vehicle safely. The brake lights and hazard warning flashers are activated during braking. When the vehicle has stopped, the hazard warning flashers will con-tinue to flash and the parking brake will beapplied. If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal. This function assumes that the brake system is intact after a collision. Brake assist is part of the Rear Collision Warning and Blind Spot Information safety systems.

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. 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.

the hill is and without the brakes needing to be applied. 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 in the OFF ROAD drive mode, the feel of the acceleratorpedal and engine response 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 at lowerspeeds if so desired.

Driving through standing water
Driving the vehicle through a deep pool of stand- ing water on a water-covered roadway is calledfording. This must be done with great caution.
To prevent damage to the vehicle when driving through water (e.g. on flooded roads): • Do not drive in water higher than the floor of the vehicle. If possible, check the depth ofthe water at its deepest point before drivingthrough it. Be particularly careful when driv-ing through flowing water.
• Always select the
Off Road drive mode
before driving in water to ensure the gasoline engine is running.
• Do not drive faster than walking speed.
• Do not stop the vehicle in the water. Drivecarefully forward or back the vehicle out ofthe water.
• Remember that waves created by passingvehicles could cause the water level to riseabove the vehicle's floor level.
• Avoid driving through salt water to help avoidthe risk of corrosion.
CAUTION
Parts of the vehicle (e.g. engine, transmission, driveline, electrical components, etc.) can bedamaged if the vehicle is driven through waterhigher than its floor level. Damage to anycomponents caused by flooding, vapor lock orinsufficient oil is not covered under warranty. If the engine stalls while the vehicle is in water, do not attempt to restart it. Have thevehicle towed on the bed of a tow truck to aworkshop - an authorized Volvo workshop isrecommended.
When you have passed the water, press lightly on the brake pedal and check that the brakes arefunctioning properly. Water, mud, slush, etc. canmake the brake linings slippery, resulting indelayed braking effect. If the vehicle is equipped with a trailer coupling contact, clean the contact after driving in water ormud.

Fuel Volvo recommends the use of detergent gaso- line to control engine deposits.
Deposit control gasoline (gasoline with detergent additives)
Detergent gasoline is effective in keeping injec- tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddriveability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.
NOTE
Volvo recommends not using external fuel injector cleaning systems, e.g. do not adddetergent additives to gasoline before or afterrefueling.
Unleaded fuelAll Volvo vehicles have a three-way catalytic con- verter and must only use unleaded gasoline. USand Canadian regulations require that pumpsdelivering unleaded gasoline are labeled"UNLEADED". Only the nozzles of these pumpswill fit in your vehicle's fuel filler inlet. It is unlaw-ful to dispense leaded fuel into a vehicle labeled"unleaded gasoline only". Leaded gasoline dam-ages the three-way catalytic converter and theheated oxygen sensor system. Repeated use ofleaded gasoline will lessen the effectiveness of
