Why is The Check Engine Light in My Lexus On?

As you are driving along the street you notice that the check engine light has come on in your Lexus. Is it a serious problem? What is the next thing that you should do? Just because the light has come on in your Lexus, it is not an immediate reason to panic. Nor is it an immediate reason to pull off to the shoulder of the road and call for the assistance of a tow truck. There are so many possibilities for what a lit check engine light may mean that it is impossible to determine what is wrong just by the presence of the light alone. Something as simple as a loose gas cap may be the cause. Or it could be the equally no need to panic broken oxygen sensor or engine misfire. With this being said, you should still bring your vehicle in for Lexus precision service to ensure that you will not end up with major problems later on. Especially during the winter months, you want to be sure that your Lexus will not just stop running due to issues with the check engine light.

How Do I Change The Car Battery In My Lexus?

Even with all of the advances so far in technology, there are currently no car batteries that are capable of lasting forever. Little things to pay attention to are the dimming of your headlights, how old the battery in your Lexus is, and whether or not your Lexus has needed a jump-start. If these apply to your Lexus, then maybe it's time to get a new battery. Ideally, you should bring your Lexus to a trusted and experienced Lexus precision service mechanic, but if the situation calls for you to change the battery in your Lexus yourself, here are some rules that you should follow. Changing a Lexus battery is quick and easy, and it can also generally be done with only the minimum amount of tool.

The most important thing to do before you begin is to make sure that the Lexus battery needs to be replaced

  • Look for a blue or whitish residue build-up around the terminal - removing this residue can sometimes solve common issues. Note: Do not touch the residue powder with your hands since it can often contains the dried form of sulfuric acid, which is extremely corrosive to skin.
  • Verify that the battery has fully been given the chance to recharge by going for a 30 minute drive with no stops. Electronics should also be turned off, including the stereo system, air conditioner, etc.
  • Take a look at the alternator. If your Lexus model also has a battery meter, while the engine is running the charge maintained by the alternator should be about 13.8 - 14.2 volts if the system is functioning properly. With the engine turned off and no accessory load, the battery should be showing a charge of about 12.4 - 12.8.
  • If you do need to replace the battery in your Lexus, it is essential that you choose the correct one for the vehicle. Some retailers will require that a "core" charge is paid if you do not bring the old battery in with you.

Before removing the battery in your Lexus:

Park on a level, flat surface that is a safe distance from open flames or traffic sparks. Engage the parking brake. Properly outfit yourself with gloves and also safety goggles. Unplug the cigarette lighter and plug the memory keeper back in. If you have misplaced the memory keeper, take note of all the electronic PIN's that may be affected.

Out with the old, in with the new:

  • Find the location of the battery on your Lexus. It will be on either side of the frame and is shaped like a rectangle with two cables that are attached to it.
  • Find the battery terminals. The terminal with a plus + sign is the positive terminal, and the terminal with the negative - sign is the negative terminal.
  • Disconnect the negative terminal in your Lexus. It will slide off easily if the negative clamp has been loosened with wrench. It is essential to disconnect the negative before the positive so that no short circuits occur.
  • Disconnect the positive terminal next.
  • Pull out the old battery and put the new one in its place. Reconnect the terminals-- positive first, then negative second.
  • Thoroughly tighten the terminal clamps with a wrench.
  • Firmly shut the hood and then start your Lexus.
  • Check to ensure that all devices are working properly, especially electronics.

Properly dispose of the old battery according to the by-laws in Toronto.

If you are not comfortable with the battery changing procedure and do not wish to do it yourself, call Ken Shaw Lexus in Toronto and let our Lexus precision service staff take care of the problem for you.

How Can I Check The Transmission Fluid Level In My Lexus?

Learning how to check the level of the transmission fluid in your Lexus is a relatively simple process. To maintain optimum vehicle health, this self-check should be done once per month. For the reading to be as accurate as possible, the vehicle should be parked on a level surface and the transmission fluid level should be checked with the Lexus running, and completely warmed up.

  • The first thing that you need to do is remove the transmission fluid dipstick. The handle is most often a bright color, such as red or yellow. If you are not certain exactly where this is located under the hood, the Lexus owner's manual has this information.
  • Once the stick has been located and removed, wipe it off on a rag, place it back in the original position, and remove it once again.
  • There are labels that are for both "Cold" and "Warm" readings. It is the warm that you will want to check.
  • If the fluid level is below full, slowly add in additional transmission fluid into where the dipstick is placed, and measure after each addition until the well is at the full line.
  • The safest way to add fluid back into the transmission is with the use of a funnel. After the filling is complete and the dipstick has been placed back in the proper hole, wait for several minutes and then check the fluid level again to ensure that it has been done properly.
  • If you do not feel comfortable checking the transmission fluid level in your Lexus by yourself, or if you believe that there may be problem, the Lexus precision service experts at Ken Shaw Lexus in Toronto, Ontario will be happy to assist you. Additionally, the Lexus transmission fluid should also be flushed at regular intervals to get rid of the accumulated dirt and grime that have settled within. Flushing intervals vary by model and this information can be found either in the owner's manual, or by taking your Toronto Lexus in to Ken Shaw Lexus to work out a preventative maintenance schedule.

Where do I find the recommendations applicable to my Lexus for oil change frequency?

Simply speak to the Lexus Precision Service department at Ken Shaw Lexus, or refer to your owner's manual. We will be happy to set up a schedule for oil changes on your Lexus that best reflects your individual needs.

How is the distance drivers can go between oil changes affected by driving conditions?

The make, model, and year of your Lexus, along with driving conditions, is why recommendations for oil changes differ from one automaker to the next. With this in mind, drivers who are considered to be "severe" will need to change their oil on a more frequent basis than "normal" drivers. To be considered "severe", driving during your typical week will consist of driving in any of the conditions below:

  • Stop-and-go traffic or excessive idling
  • Extreme humidity
  • Hauling heavy items or towing a trailer
  • Extreme heat, over 90°
  • Extreme cold, below 10°
  • Frequent trips under 5 miles

How is the warranty on my Lexus affected by less frequent oil changes?

The warranty will not be affected if the oil changes are done following the guidelines set out by the manufacturer.

Will the engine in my Lexus be harmed by less frequent oil changes?

The time between oil changes is able to be extended because of technological advances in oil and the vehicles themselves. However, drivers should adhere to manufacturer recommendations for oil changes based on their driving habits and conditions.

How Often Should I Change The Oil In My Lexus?

Most of us are familiar with the every three months, or every 5,000 kilometers, oil change schedule. This is no longer a given standard. The quality of the oil that you put in your Lexus has improved over the years, and clever manufacturers now take into account driving habits when making their recommendations for how often the oil should be changed. The frequency with which you change yours should factor in your personal driving habits.

If you drive the car on city streets for short trips only, especially in the colder months, you should get your oil changed on a three month schedule. Why? This is simply because the engine is not able to reach its optimum temperature for operating, which can lead to water condensing in the crankcase, allowing the oil to be diluted by fuel.

If your Lexus is used longer trips occasionally, it is okay to wait until six months or more have passed before changing the oil.

The warranty on your Lexus should be a main consideration when deciding how often to do your oil changes. Warranty holders are required to change their oil within certain time periods by many manufacturers. If you have a warranty like this, following the guidelines set out by the manufacturer can be well worth it. If engine repairs are needed in the future that are covered by the warranty, coverage can be declined by the manufacturer if the oil changes on your Lexus were not done as recommended.

Another thing to consider about the manufacturer's recommendations is that they have been defined after extensive and thorough testing of the engine by the automaker. They determine performance in a variety of conditions through real-world driving and lab simulations. It is this testing that helps them to develop their guidelines for how often oil changes are done, along with regular maintenance.

How Do I Check The Engine Oil Level In My Lexus?

Follow the steps listed below to check the oil level in your Lexus.

  • In order to get the most accurate reading, make sure that your vehicle is parked on a level surface.
  • Prop the hood open safely and locate the brightly colored dipstick handle (usually orange) that has the word OIL on it.Remove the dipstick and wipe it off with a rag and then replace it back into the engine, being sure to push it all the way in.
  • Remove the dipstick again. Do NOT turn it upside down when reading since this will cause the oil to run, and the reading will not be accurate. There will be two holes or lines on the bottom of the Lexus oil dipstick. Look to see where the dry section and the oily section meet. If the mark is in between the two holes or lines, then there is plenty of oil in your Lexus.
  • If the reading shows that the oil is below the lowest line or hole, you will need to add oil. Do this by adding in a liter of oil at a time, and checking after each addition until the mark falls in between the two lines or holes.

1 liter of oil for every 1,600 km is the consumption that is considered to be normal by most manufacturers. If your Lexus is using a greater amount of oil than this, it may be time to schedule an appointment for Lexus oil service, or Lexus engine service in Toronto.
