Second generation (2016–present)
First generation (2006–2015)
The Mazda CX-9 is a mid-size crossover SUV manufactured since April 2006 by Mazda in Japan, at its Ujina #1 plant in Hiroshima Prefecture.
Despite being built in Japan, the CX-9 is not sold in Japan’s domestic market, as it exceeds a major threshold in the Japanese dimension and engine displacement regulations which obligates a large annual road tax bill. Instead, the shorter and narrower Mazda CX-8 is sold in the Japanese market.
The North American version of the CX-9 debuted at the 2006 Chicago Auto Show. The European market model (built in Japan) was revealed in September 2005, while Australian models went on sale in May 2006 and Chinese models in early 2007. It replaced all three previous SUVs from Mazda: the Navajo/Ford Explorer-based MPV, the RX-8 based Tribute/Mazda Capella multi purpose vehicle and Protegé based Xedos 6. In other parts of Asia, including Brunei, Hong Kong and Taiwan it’s known as the Mazda CX-9 after being introduced there during a Mazda event called “Zoom Zoom Night” held at Taiwan Motorshow 2009.
Trim levels include Sport, Touring, Grand Touring and Signature.
The CX-9 is the first seven seater SUV to offer all-wheel drive, matched with a 6-speed automatic transmission. It also features Mazda’s i-stop idle stop system which shuts the engine off at red lights for increased fuel efficiency, along with SkyActiv technology on some models.
How to understand that your headlight bulbs need replacing?
It’s easy to overlook the importance of your vehicle’s headlights during a bright summer afternoon, but just like the lights in your home, your vehicle’s headlights need to be replaced on a regular basis to function effectively. Driving without properly functioning headlights at night or in conditions with low visibility can be a danger to yourself and others on the road. To keep your headlights bright and ensure a safe drive, here are some of the warning signs you should be watching for to know if your vehicle needs a new set of headlight bulbs.
1. Dim or faded headlights
You’re probably most familiar with this problem since it affects nearly every vehicle on the road. Headlights that are dimmed over time lose their ability to penetrate the darkness and can make your drive more difficult than it needs to be. Sometimes, all you need is a fresh set of bulbs to get your lights shining bright again. If cheap headlight replacement isn’t enough to restore the brightness in your headlights, however, the problem may be beyond what you can fix yourself and will need professional attention from an automotive technician.
2. Cloudy headlights due to dirt buildup on lenses
Another common issue that can cause cloudy or stained-looking headlights is dirt buildup on the lenses. This can be caused by normal wear and tear, including driving at speeds that kick up debris from the road or trails. Over time, dirt buildup on your vehicle’s headlights creates cloudiness that makes it harder for other drivers to see you coming. Fortunately, this issue can be quickly cleared up with a headlight restoration kit. These kits are available at automotive stores near you or online.
3. Broken bulbs
Broken or cracked lights are dangerous because the light is lost in the empty space around the crack or break. When one bulb goes out—whether due to damage or simply wearing out—a driver should replace both of their headlight bulbs as soon as possible because after one bulb burns out, the other is much more likely to do the same. Keeping a spare pair of headlights in your vehicle is a great safety measure, but you should always try to replace your bulbs right away for optimal safety on the road.
4. Uneven headlight shine from one bulb burning brighter than the other
In some cases, one headlight will burn brighter or more intensely than the other due to an issue with that particular bulb. This problem could be caused by a loose connection between the socket and the electrical system, which can result in a dimmer light on one side. If this occurs, it’s best if you have an automotive technician inspect your vehicle’s electrical system and make any necessary repairs or replacements of wiring components before driving again at night.
5. Flickering lights
If your vehicle’s headlights are flickering or blinking, this is a problem with the electrical system that could be concerning if not addressed immediately. Headlights that flicker also use more energy than they need to, so it’s best to have an automotive technician inspect your car for any issues with the alternator or battery before driving again at night. It’s probably time to schedule a service appointment if you notice flickering headlight symptoms on your vehicle.
6. Glaring lights from one side with the other dark side being lower than the lighted area of the road
Another sign of headlights needing replacement are glaring headlights on one side caused by unevenness in the road. If you notice this issue, it could be because your vehicle’s suspension needs to be adjusted and balanced so that both headlights shine at the same height. If your car does need suspension work, schedule an appointment with a certified mechanic as soon as possible so you can get back on the road safely once repairs are complete.
7. Headlights not operating at all
If none of your headlights (high beams included) come on when you turn them on or activate them, then there is likely a problem with the electrical system that must be addressed by an automotive technician right away. This is because having no lights on can make it impossible for other drivers to see your presence and avoid hitting you if they pull out in front of you, turning without looking first, or making a left turn in front of you.
How to choose the perfect headlight bulb replacement?
When you’re looking for a new headlight bulb, it’s important to find one that will fit your car perfectly. You don’t want a bulb that’s too big or too small – it needs to be just right, so before purchasing make sure that you determined the correct headlight bulb size. But how do you know what headlight bulb size you need?
There are a few things you’ll need to take into account when choosing a headlight bulb replacement. Here are some tips to help you find the perfect bulb for your car:
1. Check your car’s manual. This is the best place to start when you’re looking for a new headlight bulb. Your car’s manual will have the specific information you need about headlight bulb size and type of bulb is best for your car.
2. Consider your car’s make and model. Some cars require special headlight bulbs, so it’s important to consider your car’s make and model when you’re choosing a new bulb.
3. Think about the type of light you want. There are different types of headlight bulbs available, so you’ll need to decide which type of light you want. Do you want a bright bulb that will give you a lot of light, or a dimmer bulb that will save on energy?
4. Consider your budget. Headlight bulbs can range in price, so it’s important to consider your budget when you’re choosing a new bulb.
Are blue headlights legal?
There is no simple answer to this question as it depends on the country or state in which you are driving. In general, blue headlights are not legal in the United States. This is because blue light is at the very end of the visible spectrum and can cause significant amounts of glare for other drivers. Additionally, blue headlights can make it difficult for drivers to see the color of traffic signals. As a result, it is generally advisable to avoid using blue headlights.
Which is better xenon or LED?
There is no definitive answer to this question as it depends on personal preferences. Some people prefer the bright, white light of xenon headlights, while others prefer the more energy-efficient LED headlights. Ultimately, it is up to the individual to decide which type of headlight they prefer.
Why are some car headlights so bright?
There are a few reasons why some car headlights may be brighter than others. One reason could be the type of bulb that is being used. Some bulbs, such as HID or LED, emit a much brighter light than traditional halogen bulbs. Another reason could be the headlight housing itself. Some housings are designed to reflect and direct light in a certain way that results in a brighter light. Finally, the angle at which the headlights are pointing can also affect how bright they appear. If the headlights are pointing too high, they can cause a glare that is bothersome to other drivers. If they are pointing too low, they will not be as effective in illuminating the road ahead.
