Is it possible to tow my Acura vehicle with all four wheels on the ground (dinghy towing)?
For model year 2006 and newer, if an Acura vehicle is approved for towing with all four wheels on the ground, it will be noted in the Owner’s Manual for that vehicle. Please refer to the Owner's Manual for specific towing instructions.
For model year 2005 and older, dinghy towing capability may or may not be possible. Please contact Acura Client Relations (800-382-2238) for additional information on whether your specific 2005 or older vehicle may be dinghy-towable.
Where can I purchase an updated Navigation disc?
Updated Navigation DVDs can be purchased at www.acuranavi.com. You can also access this link through My Acura if you have registered a vehicle that has a navigation system.
The battery was disconnected from my vehicle and now my radio is flashing “code” and the radio doesn’t work. Where can I find my radio code?
If an audio unit with theft protection is disconnected from electrical power, you must enter a unique code number into the unit or it will not work. This code and the audio unit's serial number are listed on the anti-theft ID card that comes with the vehicle. The card is usually placed in the glove compartment at the time of delivery. If you cannot locate the anti-theft ID card, learn how to retrieve your radio code online by clicking here.
Note: If you own a 2014 or later Acura, your vehicle may not come with the Radio/Navigation Anti-Theft Code. Please refer to your owner’s manual for instruction on Radio/Navigation system initiation.

Why do my brakes make a squealing noise sometimes when I apply them lightly at low speeds?
As described in some Owner’s Manuals, the squealing noise is caused by high-frequency vibration of the brake pads against the rotating brake disc. Vibration is the unavoidable result of friction generated by the pads as the caliper clamps them against the rotating disc. Under average braking conditions, some brake noise is normal and cannot be eliminated.
Normally, the shims and the high-temperature grease between the pads and the brake caliper dampen and isolate most of the vibration. The level of vibration, however, is affected by outside temperature and humidity, by road conditions (mud, dust and road salt), and by the condition or thickness of the brake pad material. If the squealing noise is abnormally loud, have the brakes inspected and checked for pad wear.
Why do my brakes make a single “click” noise when I back out of a parking place and once again when I drive forward?
A clearance between the brake caliper brackets and the ends of the brake pads allows for heat expansion and helps avoid corrosion between the caliper bracket and the brake pads. That clearance can cause the pads to hit the caliper brackets when you first apply the brakes in a new direction of travel. When you back up and apply the brakes and then drive forward and apply the brakes, the single “click” noise you hear is a normal characteristic of the brake system.
Why do I hear a groaning noise when I start my car and then leave for work in the morning?
On models with a compact Anti-lock Brake System (ABS) unit, the vehicle’s ABS emits a brief grunt or groan when it does a self-check. The self-check occurs when a vehicle is backed up or driven forward after being started. The groaning noise associated with the ABS self-check is a normal characteristic; it doesn’t mean there is a problem with the ABS.
Why does my brake pedal sometimes feel like it sinks when I’m holding my car stopped at a light?
This change in brake pedal height is caused by an increase in engine vacuum. The “power brakes” system in most modern vehicles uses engine vacuum to boost the amount of force applied to the brake pedal by the driver of the car. The device that does this, called the brake “booster,” makes it easier for the driver to stop the vehicle.
Engine vacuum is affected by many different conditions. Engine vacuum is highest when all accessories are off and the accelerator pedal is released (low load), and lowest when all accessories are turned on and the accelerator pedal is held to the floor (high load). Any change in engine vacuum (load) can affect the amount of “assist,” or boost, provided by the brake booster.
One system that applies a noticeable load to the engine is the air conditioning. During normal operation, the air conditioning system constantly cycles on and off, changing the amount of load on the engine. When the air conditioning cycles off, the load on the engine is decreased and the amount of engine vacuum is increased. If the driver is applying the brake pedal when the air conditioning cycles off, the increase in engine vacuum increases the amount of boost applied to the brake pedal. That increase is felt as a slight drop in brake pedal height and is a normal characteristic.
Is it normal for my headlights to dim slightly and then come back to normal while my car is stopped at a light?
This is a normal characteristic and is caused by variations in the electrical system created by the onboard computer. The computer controls the output of the electrical charging system to improve fuel efficiency and minimize vehicle vibration.
While the engine is at idle, the computer monitors the electrical usage of the car and then controls the electrical charging system so that it charges just enough to keep up with demand. This change reduces the load on the engine and, in turn, increases fuel efficiency and reduces vehicle vibration. As electrical accessories turn on and off, the computer changes the rate of electrical charge in response to the changes in demand for electricity. As the computer responds to the addition of electrical load, you may notice a momentary dimming of the lights. For example, the headlights or instrument panel lights may briefly dim as the air conditioning cycles on.
If my vehicle has a branded or “Salvage” title, is the warranty still valid?
Vehicles with titles that have been branded as salvaged, scrapped, or dismantled are no longer covered by the new vehicle limited warranty, although the vehicle is still covered by some emissions warranties and all safety recalls. For further information regarding the branding of vehicle titles, please contact your state’s department of motor vehicles.
Can I change the size of the tires on my vehicle?
Acura does not recommend modifying the vehicle in any manner, including changing the original tire size or the suspension. Acura vehicles meet all applicable Federal Motor Vehicle Safety Standards when they are originally distributed, and modification could affect the safety performance and/or operation of the vehicle, as well as remove it from compliance with specifications and standards mandated by the federal government. As with any modification, if a failure occurs on the vehicle that can be attributed to the modification, the warranty on the affected components may be voided.
Who should I contact regarding the tire warranty on my Acura vehicle?
The tires that come as original equipment on your vehicle are warrantied by their manufacturer and not Acura. The tire warranty information is located in the glove compartment of the vehicle.
For additional warranty information or service assistance, contact the tire manufacturer directly.

What do the sidewall markings on my tire mean?
The sidewall markings on a tire provide descriptive information about the tire's design. The following refers to the tire illustration below with the sidewall marking of 225/50R16:
225 - This number specifies the width in millimeters (i.e. 225 mm).
50 - This number is the Aspect Ratio, the ratio of sidewall height to width.
R - Radial
16 - This number designates the tire's diameter in inches (i.e. 16").
92 - This number indicates the tire's load-carrying capacity, known as the Load Index; as the number for the load index increases so does the load-carrying capacity. (All passenger car tires in the U.S. are also marked with their actual load limit in pounds.)
V - This letter denotes the Speed Rating, the maximum tire speed under controlled test conditions. (“V” in this example is one of several types of speed ratings.)
psi (pounds per square inch) - The maximum cold inflation rating for the tire.
DOT (Department of Transportation) - This symbol indicates the tire meets or exceeds U.S. DOT safety standards; the letters and numbers following the DOT symbol provide information about the tire manufacturer, tire size, and the date it was manufactured.
Does Acura offer seat belt extenders to increase the length of the seat belt?
No, Acura does not offer seat belt extenders for any of our vehicles. Although some auto manufacturers do offer extenders, Acura believes they are not the best or the safest solution for our customers. As required by federal standards, Acura’s seat belts for any seating position are designed to fit 95% of all U.S. adults.
Before buying a car, you should sit in the intended seating position and adjust the seat to the most comfortable position. If you don’t feel comfortable (your legs or stomach are touching the steering wheel, or you cannot reach and operate the controls), then you cannot safely operate the vehicle and should look for a different car.
Why do my HID headlights appear uneven or out of adjustment?
The Acura models with high-intensity discharge (HID) headlights use a different beam pattern than what’s found on vehicles with conventional headlights. The top edge of each headlight beam is cut off lower on the left side, and rises toward the right side. For this reason, when the headlights are turned on, the beam pattern can appear uneven from the far left edge to the far right edge, especially when you’re closely following another vehicle or shining the headlights on a nearby wall. This apparent unevenness in the headlight beams is a normal characteristic and not something to be concerned about. Although the actual beam patterns may vary between models, a typical beam pattern found on HID-equipped Acura models has these features:
Left Side: Shines lower to avoid blinding drivers of oncoming vehicles.
Right Side: Shines higher to provide good illumination of road signs and to illuminate pedestrians.
Center: Shines below the rear window of passenger vehicles you’re following.
