A Adjust headlight aim: Observe following conditions.
– The area around the headlight is not deformed.
– The vehicle is parked on a level surface.
– Tire inflation pressure is the specified value.
– A driver is in the driver’s seat and the vehicle is in a state ready for driving (with a tank full).
– The vehicle has been bounced several times.

B Check headlight aim.
1. Prepare a thick white paper.
2. Stand the paper perpendicular to the ground at the position 9.84 ft away from the headlights.
3. Ensure that the center line of the vehicle and the paper face forms a 90-degree angle as shown in the illustration.
4. Draw a horizontal line (H line) on the paper, showing where the headlights should strike.
5. Draw a vertical line (V line) to where the center line of the vehicle is to be.
6. Draw 2 vertical lines (by connecting the low and high beam center marks) to where the both headlights should strike (V RH and V LH
7. Draw a horizontal line (by connecting the both low beam center marks) to where the headlights should strike (H RH and H LH lines).
HINT: The H RH and H LH line is 0.40 below the horizontal line (H line) of the light axis.
8. Start the engine.
9. Turn the headlights ON.
10. Check that the headlights properly strike the position shown in the illustration.

11. If not, adjust the lights in the vertical or horizontal direction.
HINT: As shown in the illustration, adjust each aim of the RH and LH lights.
c. When adjusting it in the vertical direction:
Using adjusting bolt A, adjust the headlight aim to within the specified range.
d. When adjusting it in the horizontal direction:
Using adjusting bolt B, adjust the headlight aim to within the specified range.



When performing cylinder leakage tests, the following tips might be helpful:

• Remove all spark plugs to allow easier rotation of the engine. (If this test is done
after a compression test, the plugs should already be out).

• Perform the leakage test on all cylinders, not just the problem cylinder. This would
indicate any other problems which can be rectified. This eliminates any repeat
repairs and wasted diagnostic time.

• Perform the leakage test in cylinder firing order starting with cylinder #1. It takes two
revolutions of the engine to complete the leakage test. Start at cylinder #1 and
rotate the engine to the next cylinder in the firing order. Divide the number of cylinders
into 720, the result is the number of degrees that each cylinder fires.

For example,
if you divide a 6 cylinder into 720, this equals 120 degrees. If you start at cylinder
1 and rotate the engine 120 degrees in the direction of rotation, you can check
the next cylinder in the firing order. This process eliminates the need to rotate the
engine an excessive amount.

The graphic depicts an engine with a firing order of: 1-5-3-6-2-4

If leakage is found monitoring area of loss will indicate failed component.

For example, excessive leakage on gauge and:
heard from exhaust would indicate a failed exhaust valve.
heard from intake manifold would indicate failed intake valve.
found in cooling system would indicate failed head gasket or cracked cylinder head.
heard in dipstick tube would indicate faulty piston rings.


While this year’s North American International Auto Show (NAIAS) in Detroit fe­atured many notable concept and production vehicle world debuts, the 2010 Toyota Prius garnered a considerable amount of media attention. Touting an improved 50 ­mpg rating, up from the previous iteration’s 46 mpg rating, Toyota continues to stake its reputation as an industry innovator on the economical gasoline-electric hybrid. And really, why not?

With more than 1 million units sold in 44 countries, Toyota would be hard pressed to reinvent the success of its best-selling hybrid. That is precisely why the third-generation Prius features subtle exterior re­styling backed by a surplus of technological fine-tuning. Toyota believes the silhouette of the vehicle is iconic, something they would be foolish to tamper with. So instead, the focus was directed at content and, of course, major sales growth.

“The features and performance of the new midsize Prius that you’ll see in a few moments are superior to anything we have ever built,” said Bob Carter, Toyota Division Group Vice President and General Manager, before the reveal. “And along with building a better car, we will make it available in more places. We plan to sell this new Prius in 80 countries worldwide, nearly twice as many as today. Depending on market conditions, our global sales objective will be about 400,000 units per year by 2010. That will put Prius near the top of our best-selling vehicles around the world along with Camry and Corolla.”

To appeal to a larger base of prospective drivers, and no doubt cement its reputation as a leader in hybrid-vehicle technology, Toyota has loaded the 2010 Prius with a host of new features.

For starters, the powertrain has been reworked to include a larger displacement 1.8-L four-cylinder engine with variable valve timing. Running on the Atkinson cycle, the engine produces 98 hp (73 kW) at 5200 rpm with 105 lb·ft (142 N·m) of torque. In addition, use of an electric water pump and a new exhaust gas recirculation (EGR) system are engineered to enhance fuel economy. The 1.8-L engine features reduced maintenance requirements and provides better performance, with the Prius capable of reaching 60 mph (97 km/h) from rest in 9.8 s, according to Toyota.

Though the new Prius has the same wheelbase as the current generation, it features an all-new platform. Overall length is slightly increased by 0.6 in (15 mm), partly a result of moving the front cowl forward. The suspension consists of front struts and a rear intermediate beam design, as before, but handling stability has been upgraded by improving the stabilizer layout, raising the caster angle, and tuning the bushing characteristics. Disc brakes are used on all four corners, replacing the front disc/rear drum brakes currently used.

Rounding out the package are a host of added technologies: Intelligent Parking Assist, like that available on the Lexus LS460; a standard moonroof with solar panels that power a separate ventilation system; Power, Eco, and EV driving modes; and steering-wheel touch controls that display on the instrument panel. The radar-based dynamic cruise control system features lane-departure warning. A backup monitor, voice-activated navigation system, and Safety Connect, Toyota’s version of OnStar, are also available.

2010 Prius

The 2010 Prius unveiled Monday at the North American International Auto Show in Detroit gets an average of 50 miles to the gallon. That’s a 4 mpg improvement over the current model, which already is the most fuel-efficient vehicle ranked by the EPA.

“It’s a core model for us,” Jim Lentz, president of Toyota Motor Sales USA, said in an interview before the Prius’ unveiling. “It’s a very, very important piece for us.”

The third gen Prius has a more aerodynamic design, but its exterior is easily recognizable as a Prius. Toyota says pricing will be released before the midsize sedan goes on sale in late spring.

I found this to be an interesting addition to the Prius. Well an interesting option with little benefit. Also, nothing new as far as technology goes.
Not the actual panel in the 2010 Prius


The optional solar-powered ventilation system uses an electrically powered air circulation fan that doesn’t need the engine to work. It prevents the interior air temperature from rising while the vehicle is parked.

The ventilation system can be remotely operated, so drivers can adjust the interior temperature before getting inside. Toyota says this remote air conditioning system is an industry first.

IMO: As Prius owners look for ways to improve their fuel economy and vehicle efficiency after market sources like A123 look to fill the niche. Providing a plug-in conversion (like A123), or maybe an aftermarket solar panel that suction cups to your window to charge your battery, (which provides an almost useless amount of wattage). I have seen quite a bit of these over the years. One good, many bad.

Toyota looking to capitalize on hybrid owners enviromental enthusiasm had to find a way to incorporate a solar panel into the 3rd gen Prius. Think of this solar panel as the loud exhaust of a hotrod, Not adding much bite but lots of bark. Thats the way I see it. Marketing hype, from Toyota to you.

Audi first incorporated a solar panel into the sunroof for cabin temperature maintenance in 2000. Like I mentioned, no new technology here. IMO-marketing hype.

Even in very low sunlight, light-sensitive elements under the glass sunroof panel produce electricity to power the ventilator inside the vehicle. Even when the ignition is switched off, the interior will be supplied with a continuous flow of fresh air and temperature levels inside the vehicle can be reduced by as much as 50% with the outside air that is cleaned as is passes through the dust and pollen filter. This kind of ventilation does not put any additional demands on the car’s battery. This preliminary cooling lets the air conditioner cool the interior to the desired temperature with little energy and use of the ventilator.

VW’s 282 MPG Super Fuel Efficient Car

The 1-Liter car has been around in prototype form since 2002 and greens everywhere have been drooling at its 282 miles per gallon fuel economy (or 1 liter of gasoline per 100 kilometers, hence the name). VW has finally decided to make more and sell them, and a limited edition (estimated in the thousands) should start selling in 2010.

1-Liter Car Technical Specs
The 1-Liter car (or 1-Litre, over in Europe) weights only 660 pounds. The body is made from carbon composites and it is shaped to be extremely aerodynamic, giving it a coefficient of drag of only 0.16 (the average car comes in around 0.30 and the Honda Insight had a Cd of 0.25). The prototype was powered by a 1-cylinder diesel engine, but the production model should have a 2-cylinder diesel, and may have a stop-start anti-idling feature.

The car has anti-lock brakes, stability control and airbags.

According to Canadian Driver,

“Volkswagen says the One-Liter Car is as safe as a GT sports car registered for racing. With the aid of computer crash simulations, the car was designed with built-in crash tubes, pressure sensors for airbag control and front crumple zones.”

DETROIT – Toyota Motor Corp. said Saturday it is confirming plans to have an all-electric vehicle on U.S. roads by 2012 by introducing an ultra-compact battery-powered concept car at the North American International Auto Show in Detroit.

Toyota calls the FT-EV, based on the ultra-compact iQ model on sale in Japan, an “urban dweller” with a range of 50 miles. Although there’s no guarantee it will go into production in its current form, it illustrates the company’s product strategies.

“Last summer’s $4-a-gallon gasoline was no anomaly,” said Irv Miller, vice president of Toyota Motor Sales USA. “It was a brief glimpse of our future. We must address the inevitability of peak oil by developing vehicles powered by alternatives to liquid-oil fuel.”

The FT-EV marks Toyota’s deepest foray yet into non-gasoline vehicles and comes as a challenge to competitors like General Motors Corp. and Chrysler LLC, which are rushing to roll out alternatives to gasoline cars.

GM says it plans to have the highly anticipated Chevrolet Volt in showrooms by 2010. The rechargeable gas-electric car is expected to travel 40 miles on electricity alone, then a gasoline engine kicks in to extend its range.

Chrysler, meanwhile, unveiled three electric car prototypes last year — a Dodge sports car, a Jeep Wrangler and a Chrysler minivan, and said it plans to put one of the three on sale next year.

In addition to the FT-EV, Toyota said it is expanding its offering of hybrid cars by launching as many as 10 new hybrid models by early next decade in markets around the world. It also said it will start global delivery of 500 Toyota Prius plug-in hybrids powered by lithium-ion batteries later this year, instead of in 2010 as originally planned. Of those, 150 will go to U.S. lease and fleet customers.

Hybrids like the Prius currently run on heavier, weaker nickel-metal hydride batteries, and they recharge through energy captured from the vehicle’s braking.

Toyota said electric vehicles like the FT-EV and new smaller vehicles like the iQ will be a key component of the Japanese automaker’s environmentally conscious strategy, but the conventional gas-electric hybrid, like the Prius, is considered the company’s long-term core powertrain technology.

Toyota is set to unveil its 2010 Prius hybrid and a Lexus hybrid called the HS250h at the Detroit auto show, which starts Sunday with three days of media previews. The show opens to the public Jan. 17-25.
