capacity weight or maximum permissible axle loads are not exceeded.
• At the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned morethan 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.

Driving through standing 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 9 in. (25 cm) at walkingspeed. Be particularly careful when drivingthrough flowing water. • Take particular care when driving through flowing water.
• After driving through water, apply the brakesand check that they are functioning correctly.
• 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.
• Avoid driving through salt water if at all pos-sible to help avoid the risk of corrosion.
CAUTION
• Engine damage will occur if water is drawn into the air cleaner.
• 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.
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.

Engine
temperature/Stop safely will be displayed.
Stop the vehicle as soon as possible in a safe place and let the engine idle for severalminutes.
• If the message
Engine temperature/High
temperature Turn off engine or Engine
coolant/Stop safely is displayed, stop
safely and turn off the engine.
• If the transmission begins to overheat, an alternative gear shifting program will beselected. An integrated protective functionwill also by activated, the warning symbol will illuminate and the message
Transmission
warmHigh temperature Reduce speed
or Transmission warmStop safely, wait
for cooling will be displayed in the instru-
ment panel. •

Towing recommendations
Always check with state and local authorities before attempting to tow another vehiclebecause this type of towing is subject to regula-tions regarding maximum towing speed, lengthand type of towing device, lighting, etc.
Towing your vehicle behind another vehicle
1. After securely attaching the towing line to both vehicles, put the gear selector in posi- tion N and release the parking brake.
2. Put the ignition in mode II by turning the
start knob to START (without depressing
the brake pedal) and hold it in this position
for approx. 4 seconds. Release the knob.
3. Put the gear selector in position N and
release the parking brake.
4. The towing vehicle can now begin driving.
5. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This will help prevent jar-ring movements of the vehicle being towed.
6. Be prepared to apply the brakes to stop the vehicle being towed.
CAUTION
General towing precautions:
• If the vehicle's battery is dead, an auxiliary battery will be necessary to provide cur-rent for releasing the electric parkingbrake and to move the gear selector from the
P position to N. If this is not possible,
use the shiftlock override procedure tomanually release the gear selector from P
and move it to N.
• Maximum speed: 50 mph (80 km/h). Do not exceed the maximum allowable tow-ing speed.
• Maximum distance with front wheels onground: 50 miles (80 km).
• The vehicle should only be towed in theforward direction.
WARNING
• When the vehicle is being towed, the igni- tion should be in mode
II (in mode I, all of
the vehicle's airbags are deactivated).
• The remote key must remain inside the vehicle.
• The power brakes and power steering willnot function when the engine is not run-ning. Approximately 5 times more pres-sure will be required on the brake pedaland the steering wheel will be considera-bly harder to turn.
• The towing eyelets must not be used forpulling the vehicle out of a ditch or forany similar purpose involving severestrain.

Opening/closing the fuel filler door The fuel tank has a filling system that does not have a cover.
Opening/closing the fuel filler doorThe vehicle must be unlocked before the fuel filler door can be opened.An arrow next to the fuel pumpsymbol in the instrument panelindicates the side of the vehiclewhere the fuel filler door islocated.
1. Open the fuel filler door by pressing lightlyon its rear edge.
2. After refueling, close the fuel filler door by pressing lightly.
Refueling from a service station pump
To refuel:
1. Open the fuel filler door. Do not refuel with
the engine running 1
2. Insert the pump's nozzle into the fuel filler pipe's opening as far as possible (see the
illustration).
3. Avoid overfilling the fuel tank. Do not press the handle on the filler nozzle after it has stopped pumping. Too much fuel in the tankin hot weather conditions can cause the fuelto overflow. Overfilling could also cause dam-age to the emission control systems.
CAUTION
Avoid spilling gasoline during refueling. In addition to causing damage to the environ-ment, gasolines containing alcohol can causedamage to painted surfaces, which may notbe covered under the New Vehicle LimitedWarranty.

Driving with a trailer
When towing a trailer, always observe the legal requirements of the state/province.
• 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.
• 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%.

How TSA worksOnce swaying has begun, it can be very difficult to 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. TSA is deactivated if the driver deactivates
ESCin the center display's menu system.
When the ESC symbol in the
instrument panel flashes, TSA is active.

CAUTION
• When starting in cold weather, the auto- matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
• Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
• The engine should be idling when youmove the gear selector. Never accelerateuntil after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harsh engage-ment and premature transmission wear.
• Selecting
P or N when idling at a stand-
still for prolonged periods of time will helpprevent overheating of the automatictransmission fluid.
