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.

Automatic release
1. Start the engine.
NOTE
•For safety reasons, the parking brake is only released automatically if the engine isrunning and the driver is wearing a seatbelt.
• The electric parking brake will be releasedimmediately when the accelerator pedal ispressed and the gear selector is in posi- tion
D or R.
2. Fasten the seat belt. 3.
Move the gear selector to position D or R
and press the accelerator pedal. The parking brake will release when the vehicle begins tomove.
Heavy load uphill
A heavy load, such as a trailer, can cause the vehicle to roll backward when the parking brakeis released automatically on a steep incline. Tohelp avoid this:
1. Keep the electric parking brake lever pushed in with the left hand while shifting into Drive with the right.
2. While pressing the accelerator pedal to pull away, release the parking brake lever onlyafter the vehicle begins to move.

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.

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.

If the automatic transmission begins to over- heat, a message will be displayed in the textwindow.
• 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%.

Trailer Stability Assist (TSA)
Trailer Stability Assist is a system designed to help stabilize a vehicle that is towing a trailerwhen the vehicle and trailer have begun to swayand is part of the stability system. For informationon the stability system, see Stability system –introduction (p. 174)
FunctionA vehicle towing a trailer may begin to sway for various reasons. Normally this only occurs at highspeeds but, for example, if the trailer is overloa-ded or if the load is unevenly distributed in thetrailer, there is risk of swaying at speeds betweenapproximately 45-55 mph (70-90 km/h). Swaying may be caused by factors such as:
• The vehicle and trailer are hit by a sudden, strong crosswind
• The vehicle and trailer are traveling on anuneven road surface or drive over a bump
• Sudden movements of the steering wheel
Facts about TSA
• TSA intervenes at speeds above approxi-mately 40 mph (60 km/h)
• The stability system symbol in the instrumentpanel will flash when TSA is working
• If the driver switches off the stability system'sSpin Control function, TSA will also beswitched off (but will be on again the nexttime the engine is started) •
TSA may not intervene when the vehicle andtrailer begin to sway if the driver tries to com-pensate for the swaying motion by movingthe steering wheel rapidly
How TSA worksOnce swaying has begun, it can be very difficultto stop, which makes it difficult to control thevehicle and trailer. The TSA system continuously monitors the vehi- cle's movements, particularly lateral movement. Ifthe system detects a tendency to sway, thebrakes are applied individually on the frontwheels, which has a stabilizing effect on the vehi-cle and trailer. This is often enough to enable thedriver to regain control of the vehicle. If this is not adequate to stop the swaying motion, the brakes are applied to all of the wheels on thevehicle and on the trailer if it is equipped withbrakes, and engine power is temporarily reduced.As the swaying motion begins to decrease andthe vehicle-trailer have once again become sta-ble, TSA will now stop regulating the brakes/engine power and the driver regains control ofthe vehicle.
