WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan, so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition.
WARNING (Diesel only): Never work on injection system with engine
running or within 30 seconds after shutting off engine. High pressure pump, rail, injec-tors and high pressure pipes are subject tohigh pressure even after the engine stopped.The fuel jet produced by fuel leaks maycause serious injury, if it touch the body.People using pacemakers should not movethan 30cm closer to the ECU or wiring har-ness within the engine room while engine isrunning, since the high currents in the Com-mon Rail system produce considerable mag-netic fields.
The fluid level in the brake fluid reservoir shouldbe checked periodically. The level should bebetween the "MIN" and "MAX" marks on theside of the reservoir. If the level is at or belowthe "MIN" mark, carefully add fluid to bring it upto "MAX". Do not overfill.

the top of the front seatbacks. This could allow cargo to slide forward and cause injury or damage during sudden stops.
o When you return the folded down
seatback to its upright position, alwaysbe sure to install the headrests in their proper positions. Headrests are impor- tant to the safety of occupants in a rear collision. If the headrests are not in- stalled in their proper position, serious injury or death could result if a rear end collision occurs.

CHILD RESTRAINT SYSTEM Children riding in the car should sit in the rear
seat and must always be properly restrained to minimize the risk of injury in an accident, sudden stop or sudden maneuver. According to accident statistics, children are safer when properly restrained in the rear seats than in the front seat. Larger children should use one of the seat belts provided.
You are required by law to use safety re-
straints for children. If small children ride in your vehicle you must put them in a child restraint system (safety seat).
Children could be injured or killed in a crash if
their restraints are not properly secured. Forsmall children and babies, a child seat or infant seat must be used. Before buying a particular child restraint system, make sure it fits your car and seat belts, and fits your child. Follow all the instructions provided by the manufacturer when installing the child restraint system.

To Release the Seat Belt
B220C01FC
When you want to release the seat belt, press
the button in the locking buckle.
WARNING: The centre lap belt latching mechanism is
different from those for the rear seat shoul-der belts. When fastening the rear seat shoulder belts or the centre lap belt, make sure they are inserted into the correct buckle to obtain maximum protection from the seat belt system and assure proper operation.

Too high
With a 2-point static type seat belt, the length
must be adjusted manually so it fits snugly around your body. Fasten the belt and pull on the loose end to tighten. The belt should be placed as low as possible on your hips, not on your waist. If the belt is too high, it could increase the possibility of your being injured in an accident because you could slide under it.

WARNING:
o A child restraint system must be placed in the rear seat. Never install a child orinfant seat on the front passenger's seat.Should an accident occur and cause the passenger side airbag to deploy, it could severely injure or kill an infant or child seated in an infant or child seat. Thus, only use a child restraint in the rear seat of your vehicle.
o Since a safety belt or child restraint system can become very hot if it is leftin a closed vehicle, be sure to check the seat cover and buckles before placing a child there.
o When the child restraint system is not in use, fasten it with a safety belt so thatit will not be thrown forward in the case of a sudden stop or an accident.
o Children who are too large to be in a
child restraint should still sit in the rear seat and be restrained with the avail- able lap/shoulder belts. Never allow children to ride in the front passenger seat.
o Always make sure that the shoulder belt portion of the outboard lap/shoulder beltis positioned midway over the shoul- der, never across the neck or behind the back. Moving the child closer to the center of the vehicle may help provide a good shoulder belt fit. The lap belt por- tion of the lap/shoulder belt or thecenter seat lap belt must always be positioned as low as possible on the child's hips and as snug as possible.
o If the seat belt will not properly fit the child, we recommend the use of anapproved booster seat in the rear seat in order to raise the child's seating height so that the seat belt will prop- erly fit the child.
o Never allow a child to stand up or kneel on the seat.
o Never use an infant carrier or child
safety seat that "hooks" over aseatback; it may not provide adequate security in an accident.
o Never allow a child to be held in a person's arms while they are in a mov-ing vehicle, as this could result in se- rious injury to the child in the event of an accident or a sudden stop. Holding a child in a moving vehicle does not provide the child with any means of protection during an accident, even if the person holding the child is wearing a seat belt.
o If the child restraint seat is not an- chored properly, the risk of a childbeing seriously injured or killed in a collision greatly increases. B230F01A-EAT Installation on Rear Seat Centre Posi- tion Use the centre seat belt for the rear to secure the child restraint system as illustrated. After installation of the child restraint system, rock the child seat back and forth, and side to side to ensure that it is properly secured by the seat belt.If the child seat moves, readjust the length of the seat belt. Then, if equipped, insert the child restraint tether strap hook into the child re- straint hook holder and tighten to secure the seat. Always refer to the child restraint sys- tem manufacturer’s recommendation before installing the child restraint system in your vehicle.
