2013 RDX uuBrakinguBrake System


■ Foot Brake Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist helps reduce the effort needed on the brake pedal. The brake assist system increases the stopping force when you depress the brake pedal hard in an emergency situation. The anti-lock brake system (ABS) helps you retain steering control when braking very hard.


2 Brake Assist System P. 260
2 ABS (Anti-lock Brake System) P. 259


1Foot Brake


Check the brakes after driving through deep water, or if there is a buildup of road surface water. If necessary, dry the brakes by lightly depressing the pedal several times.


If you hear a continuous metallic friction sound when applying the brakes, the brake pads need to be replaced. Have the vehicle checked by a dealer.


Constantly using the brake pedal while going down a long hill builds up heat, which reduces the brake effectiveness. Apply engine braking by taking your foot off the accelerator pedal and downshifting to a lower gear.


Do not rest your foot on the brake pedal while driving, as it will lightly apply the brakes and cause them to lose effectiveness over time and reduce pad life. It will also confuse drivers behind you.


Your vehicle is equipped with a hydraulic brake booster that, under certain conditions, such as braking at high altitudes, supplements the vacuum power assist. When the hydraulic brake booster activates, you may hear a motor sound and a slight vibration in the pedal. This is normal.

2013 RDX ABS (Anti-lock Brake System) ■ ABS Helps prevent the wheels from locking up, and helps you retain steering control by pumping the brakes rapidly, much faster than you.


The electronic brake distribution (EBD) system, which is part of the ABS, also balances the front-to-rear braking distribution according to vehicle loading.


You should never pump the brake pedal. Let the ABS work for you by always keeping firm, steady pressure on the brake pedal. This is sometimes referred to as “stomp and steer.”


■ ABS operation The brake pedal may pulsate slightly when the ABS is working. Keep holding the pedal firmly down. On dry pavement, you will need to press on the brake pedal very hard before the ABS activates. However, you may feel the ABS activate immediately if you are trying to stop on snow or ice.


When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.


uuBrakinguABS (Anti-lock Brake System)


QRG


1ABS (Anti-lock Brake System)


NOTICE The ABS may not function correctly if you use an incorrect tire type and size.


When the ABS indicator comes on while driving, there may be a problem with the system. While normal braking is not affected, there is a possibility of the ABS not operating. Have the vehicle checked by a dealer immediately.


The ABS does not reduce the time or distance it takes to stop the vehicle. It only helps with steering control during hard braking.


In the following cases, your vehicle may need more stopping distance than a vehicle without the ABS: • When driving on rough road surfaces, including


when driving on uneven surfaces, such as gravel or snow.


• When tire chains are installed.

2013 RDX Refueling


Fuel Information ■ Fuel recommendation Unleaded premium gasoline, pump octane number 91 or higher Use of lower octane gasoline can cause occasional metallic knocking noise in the engine and will result in decreased engine performance. Use of gasoline with a pump octane less than 87 can lead to engine damage.


■ Top tier detergent gasoline Because the level of detergency and additives in gasoline vary in the market, Acura endorses the use of “TOP TIER Detergent Gasoline” where available to help maintain the performance and reliability of your vehicle. TOP TIER Detergent Gasoline meets a new gasoline standard jointly established by leading automotive manufacturers to meet the needs of today’s advanced engines.


Qualifying gasoline retailers will, in most cases, identify their gasoline as having met “TOP TIER Detergent Gasoline” standards at the retail location. This fuel is guaranteed to contain the proper level of detergent additives and be free of metallic additives. The proper level of detergent additives, and absence of harmful metallic additives in gasoline, help avoid build-up of deposits in your engine and emission control system.


For further important fuel-related information for your vehicle, or on information on gasoline that does not contain MMT, visit My Acura at owners.acura.com In Canada, visit www.acura.ca for additional information on gasoline. For more information on top tier gasoline, visit www.toptiergas.com.


■ Fuel tank capacity: 16 US gal (60 liters)


1Fuel Information


NOTICE We recommend quality gasoline containing detergent additives that help prevent fuel system and engine deposits. In addition, in order to maintain good performance, fuel economy, and emissions control, we strongly recommend the use of gasoline that does NOT contain harmful manganese-based fuel additives such as MMT, if such gasoline is available.


Use of gasoline with these additives may adversely affect performance, and cause the malfunction indicator lamp on your instrument panel to come on. If this happens, contact a dealer for service. Some gasoline today is blended with oxygenates such as ethanol. Your vehicle is designed to operate on oxygenated gasoline containing up to 10% ethanol by volume. Do not use gasoline containing methanol. If you notice any undesirable operating symptoms, try another service station or switch to another brand of gasoline.

Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel. • Stop the engine, and keep heat, sparks,


and flame away.


• Handle fuel only outdoors. • Wipe up spills immediately.


The filler nozzle automatically stops to leave space in the fuel tank so that fuel does not overflow as a result of changes in air temperature.


If the fuel filler nozzle keeps turning off when the tank is not full, there may be a problem with the pump's fuel vapor recovery system. Try filling at another pump. If this does not fix the problem, consult a dealer.


Do not continue to add fuel after the nozzle has automatically stopped. Additional fuel can exceed the full tank capacity.


2013 RDX Fuel Economy


Improving Fuel Economy Fuel economy depends on several conditions, including driving conditions, your driving habits, the condition of your vehicle, and loading. Depending on these and other conditions, you may or may not achieve the rated fuel economy of this vehicle.


■ Maintenance and Fuel Economy You can optimize your fuel economy with proper maintenance of your vehicle. Always maintain your vehicle in accordance with the messages displayed on the multi-information display.


• Use the recommended viscosity engine oil, displaying the API Certification Seal.


• Maintain the specified tire pressure.


• Do not load the vehicle with excess cargo.


• Keep your vehicle clean. A buildup of snow or mud on your vehicle's underside


adds weight and increases wind resistance.

NOTICE Halogen bulbs get very hot when lit. Oil, perspiration, or a scratch on the glass can cause the bulb to overheat and shatter.


The headlight aim is set by the factory, and does not need to be adjusted. However, if you regularly carry heavy items in the cargo area or tow a trailer, have the aiming readjusted at a dealer or by a qualified technician.


The HB3 and H11 types are halogen bulbs. When replacing a bulb, handle it by its base, and protect the glass from contact with your skin or hard objects. If you touch the glass, clean it with denatured alcohol and a clean cloth.


The exterior lights' inside lenses (headlights, brake lights, etc.) may fog temporarily after a vehicle wash or while driving in the rain. This does not impact the exterior light function. However, if you see a large amount of water or ice accumulated inside the lenses, have your vehicle inspected by a dealer.
