Active chassis * (Four C)
Active chassis, Four-C (Continuously Controlled Chassis Concept), regulates the characteristicsof the shock absorbers so that the vehicle's driv-ing characteristics can be adjusted. There arethree settings: Comfort, Sport and Advanced.
Operation
Chassis settings
Use the buttons in the center console to change setting. The setting in use when the engine isswitched off is activated the next time the engineis started.
NOTE
This system is available on Canadian models only.
Comfort
Comfort mode offers a somewhat softer ride and the transmission shifts gears at lower rpm. Thismode is particularly suitable for long-distancehighway driving. The indicator light in the buttonwill be on when this mode is selected.
Sport
In this mode, the vehicle's body sway is reduced during cornering and steering response is moreimmediate. The transmission shifts up at higherrpm for sportier driving. The indicator light in thebutton will be on to indicate that Sport mode hasbeen selected.
Advanced
In this mode, body sway in curves is minimal and steering response is very direct. Gear shifting isdone at high rpm in each gear for dynamic andactive driving.

Collision warning
* – limitations
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver is notlooking straight ahead may make the visual warn-ing signal in the windshield difficult to see. Forthis reason, always activate the audible warningsignal. Slippery driving conditions increase braking dis- tance, which can reduce the system's capacity toavoid a collision. In these conditions, the ABS andstability systems provide the best possible brak-ing effect while helping to maintain stability.
NOTE
The visual warning signal may be temporarily disengaged in the event of high passengercompartment temperature due to strong sun-light, etc. If this occurs, the audible warningsignal will be used, even if it has been deacti-vated in the menu system.

STARTING AND DRIVING
265
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect onthe brake discs and pads. This will cause a delayin braking effect when the pedal is depressed. Toavoid such a delay when the brakes are needed,depress the pedal occasionally when drivingthrough rain, slush, etc. This will remove the waterfrom the brakes. Check that brake applicationfeels normal. This should also be done afterwashing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain whendriving in mountains or hilly areas, or when towinga trailer. Vehicle speed is usually slower, whichmeans that the cooling of the brakes is less effi-cient than when driving on level roads. To reducethe strain on the brakes, shift into a lower gearand let the engine help with the braking. Do notforget that if you are towing a trailer, the brakeswill be subjected to a greater than normal load.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.

Anti-lock braking system (ABS) The ABS system helps to improve vehicle con- trol (stopping and steering) during severe brak-ing conditions by limiting brake lockup.
When the system "senses" impending lockup, braking pressure is automatically modulated inorder to help prevent lockup that could lead to askid. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.

Brake lights The brake lights come on automatically when the brakes are applied.
Adaptive brake lights
The adaptive brake lights activate in the event of sudden braking or if the ABS system is activated.This function causes an additional taillight oneach side of the vehicle to illuminate to help alertvehicles traveling behind. The adaptive brake lights activate if:
• The ABS system activates for more than approximately a half second
• In the event of sudden braking while thevehicle is moving at speeds above approxi-mately 6 mph (10 km/h).
When the vehicle has come to a stop, the brakelights and additional taillights remain on for aslong as the brake pedal is depressed or untilbraking force on the vehicle is reduced.

Emergency Brake Assistance (EBA)
EBA is designed to provide full brake effect immediately in the event of sudden, hard brak-ing.
Emergency Brake AssistanceThe EBA system is activated by the speed with which the brake pedal is depressed. When the EBA system is activated, the brake pedal will go down and pressure in the brake sys-tem immediately increases to the maximum level.Maintain full pressure on the brake pedal in orderto utilize the system completely. EBA is automati-cally deactivated when the brake pedal isreleased.

NOTE
•When the EBA system is activated, the brake pedal will go down and pressure inthe brake system immediately increasesto the maximum level. You must maintainfull pressure on the brake pedal in orderto utilize the system completely. Therewill be no braking effect if the pedal isreleased. EBA is automatically deacti-vated when the brake pedal is released.
• When the vehicle has been parked forsome time, the brake pedal may sinkmore than usual when the engine isstarted. This is normal and the pedal willreturn to its usual position when it isreleased.

NOTE
•
A faint sound from the parking brake's electric motor can be heard when theparking brake is being applied. Thissound can also be heard during the auto-matic function check of the parkingbrake.
• The brake pedal will move slightly whenthe electric parking brake is applied orreleased.
Low battery voltageIf the battery voltage is too low, the parking brake cannot be applied or released.
Connect
an auxiliary battery if the battery voltage is toolow, see Jump starting (p. 251).
Parking on a hill
• If the vehicle is pointing uphill, turn the frontwheels so that they point away from the curb.
• If the vehicle is pointing downhill, turn thefront wheels so that they point toward thecurb.
The parking brake should also be applied.

Driving through water
The vehicle should be driven with extreme cau- tion if it is necessary to drive through standingwater.
The vehicle can be driven through water up to a depth of approximately 13 in. (35 cm) at walkingspeed to help prevent water from entering thedifferential and the transmission. Water reducesthe oil's lubricating capacity and may shorten theservice life of these components.
• Take particular care when driving throughflowing water.
• Clean the electrical connections for trailerwiring after driving in mud or water.
• When driving through water, maintain lowspeed and do not stop in the water.
WARNING
•Avoid driving through standing or rushing water. Doing so can be dangerous and itmay also be difficult to determine theactual depth of the water.
• If water cannot be avoided, after drivingthrough the water, press lightly on thebrake pedal to ensure that the brakes arefunctioning normally. Water or mud canmake the brake linings slippery, resultingin delayed braking effect.
CAUTION
•Engine damage will occur if water is drawn into the air cleaner.
• If the vehicle is driven through waterdeeper than approximately 13 in.(35 cm), water may enter the differentialand the transmission. This reduces theoil's lubricating capacity and may shortenthe service life of these components.
• Damage to any components, the engine,transmission, turbo-charger, differential orits internal components caused by flood-ing, vapor lock or insufficient oil is notcovered under warranty.
• Do not allow the vehicle to stand in waterup to the door sills longer than absolutelynecessary. This could result in electricalmalfunctions.
• If the engine has been stopped while thevehicle is in water, do not attempt torestart it. Have the vehicle towed out ofthe water.

Engine and cooling system
Under special conditions, for example when driv- ing in hilly terrain, extreme heat or with heavyloads, there is a risk that the engine and coolingsystem will overheat.
Proceed as follows to avoid overheating the engine.
• Maintain a low speed when driving with atrailer up long, steep hills. For information,see Towing a trailer (p. 279)
• Do not turn the engine off immediately whenstopping after a hard drive.
WARNING
The cooling fan may start or continue to oper- ate (for up to 6 minutes) after the engine hasbeen switched off.
• Remove any auxiliary lights from in front of the grille when driving in hot weather condi-tions.
• Do not exceed engine speeds of 4500 rpm ifdriving with a trailer in hilly terrain. The oiltemperature could become too high.

WARNING
Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous exhaust gases entering the passenger com-partment. If the tailgate must be kept open forany reason, proceed as follows:
• Close the windows
• Set the ventilation system control to airflow to floor, windshield and side windowsand the blower control to its highest set-ting.
Handling and roadholdingAt the specified curb weight your vehicle has a tendency to understeer, which means that thesteering wheel has to be turned more than mightseem appropriate for the curvature of a bend.This ensures good stability and reduces the riskof rear wheel skid. Remember that these proper-ties can alter with the vehicle load. The heavierthe load in the cargo area, the less the tendencyto understeer.
• Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so thatcapacity weight or maximum permissible axleloads are not exceeded.
• At the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned more than might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alterwith the vehicle load. The heavier the load inthe cargo compartment, the less the ten-dency to understeer.

Towing a trailer When towing a trailer, always observe the legal requirements of the state/province.
NOTE
For the maximum trailer and tongue weights recommended by Volvo, see Weights (p. 372)
• All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
• Increase tire pressure to recommended fullpressure, see the tire inflation decal on thedriver's door opening.
• When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.

WHEELS AND TIRES
305
prevent the tire pressure monitoring system from functioning properly. Always check the system's malfunction telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement oralternate tires and wheels allow the system tocontinue to function properly.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation decal on the driver'sdoor opening or consult your Volvo retailer.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.

Tire Monitor - introduction (p. 305)
• Tire Pressure Monitoring System (TPMS) – general information (p. 308)
Tire Monitor - introduction Tire Monitor uses the rotational speed of the tires in combination with signal analysis of theABS sensor signals to determine if they areproperly inflated.
When a tire is under-inflated, its diameter (and consequently also its rotational speed) changes.By comparing the individual tires with each otherit is possible to determine if one or more tires areunder inflated. When low inflation pressure is detected or if the system is not functioning properly, Tire Monitorwill light up the tire pressure warning light (
) (also referred to as a telltale) in the
instrument panel and will display one of several messages in the text window, for example:
Tire
pressure low Check tires. Adjust the inflation
pressure and recalibrate if necessary.
NOTE
If a malfunction occurs in the system, the tire pressure warning light will flash for approxi-mately 1 minute and then remain illuminated.
Tire press. syst Service required will be
displayed.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation decal on the driver'sdoor opening or consult your Volvo retailer.
