STARTING AND DRIVING
271
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.

M+S or M/S = Mud and Snow, AT = All Ter-
rain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and
indicates that the tire meets all federalstandards. The next two numbers or lettersare the plant code where it was manufac-tured, the next two are the tire size code andthe last four numbers represent the weekand year the tire was built. For example,1510 means that the tire was manufacturedduring week 15 of 2010. The numbers inbetween are marketing codes used at themanufacturer's discretion. This informationhelps a tire manufacturer identify a tire forsafety recall purposes.
9. Tire Ply Composition and MaterialUsed : Indicates the number of plies indi-
cates or the number of layers of rubber-coated fabric in the tire tread and sidewall.Tire manufacturers also must indicate the plymaterials in the tire and the sidewall, whichinclude steel, nylon, polyester, and others.
10. Maximum Load : Indicates the maximum
load in pounds and kilograms that can becarried by the tire. Refer to the vehicle's tireinformation placard located on the B-Pillarfor the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperaturegrades : see Tire specifications – Uniform
Tire Quality Grading (p. 302) for more infor-mation. 12.
Maximum permissible inflationpressure: the greatest amount of air pres-
sure that should ever be put in the tire. Thislimit is set by the tire manufacturer.
Loading specifications Properly loading your vehicle will provide maxi- mum return of vehicle design performance.
Before loading your vehicle, familiarize yourself with the following terms for determining yourvehicle's weight ratings, with or without a trailer,from the vehicle's Federal/Canadian Motor Vehi-cle Safety Standards (FMVSS/CMVSS) label, andthe vehicle's tire information placard:
Curb weightThe weight of the vehicle including a full tank offuel and all standard equipment. It does notinclude passengers, cargo, or optional equipment.
Capacity weightAll weight added to the curb weight, includingcargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.
Permissible axle weightThe maximum allowable weight that can be car-ried by a single axle (front or rear). These num-bers are shown on the Federal/Canadian MotorVehicle Safety Standards (FMVSS/CMVSS) label.The total load on each axle must never exceed itsmaximum permissible weight.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passengers.

NOTE
•The location of the various labels in your vehicle, see Label information (p. 366).
• A table listing important weight limits foryour vehicle, see Weights (p. 372).
Loading specifications – load limit The load limit of your vehicle is the combined weight of the occupants and cargo.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle's plac-ard.
2. Determine the combined weight of the driver and passengers that will be riding in yourvehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and luggage load capacity.For example, if the "XXX" amount equals1400 lbs. and there will be five 150 lb. pas-sengers in your vehicle, the amount of availa-ble cargo and luggage load capacity is650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculatedin Step 4. 6. If your vehicle will be towing a trailer, load
from your trailer will be transferred to yourvehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.WARNING
• Exceeding the permissible axle weight, gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
• Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.
