How to seal the flat tire S09AC0302 To seal the flat tire, perform the following steps. . First, pump in the sealant and air. Drive the vehicle for approximately 10 minutes or 3 miles (5 km) so that the sealant can seal the damaged area. . Stop the vehicle again, check and, if necessary, adjust the pressure of the damaged tire. . After that, you can continue to drive carefully no faster than 50 mph (80 km/h) and within the maximum distance of 125 miles (200 km). Inform all other users of the vehicle that the tire has been temporarily sealed with the flat tire repair kit and make them aware of the special driving conditions to be observed. 1. Shake the sealant bottle well. Loosen the hose. 1) Valve 2. Connect the air compressor hose to the valve on the bottle. CAUTION . Make sure that the air compressor switch is OFF. . The sealant may leak if the fitting is not tight enough. 15 16 Connect the hose from the bottle to the tire valve stem tightly. CAUTION The sealant may leak if the fitting is not tight enough. 3. Turn the bottle upside down and tilt the bottle cap into the bottle holder of the air compressor. Make sure that the air compressor switch is OFF. 4. Connect the power plug of the air compressor into the accessory power outlet. Apply the parking brake and turn on the ignition switch to the “ACC” position. Turn the air compressor switch on and adjust the air pressure to the appropriate level (green zone of the air gauge). CAUTION . Do not run the air compressor for more than 10 minutes as it can get hot. Be careful not to get burned. . If tire pressure does not reach the green zone for 10 minutes, this kit will be unable to seal the tire. Contact your SUBARU dealer for help. NOTE . After the compressor starts to operate, the air pressure will temporarily rise to 45 psi (300 kPa, 3.0 kgf/cm2) or higher. After about 30 seconds when all of the sealant is inside the tire, the air pressure will lower, representing the air pressure in the tire. . In extremely low temperatures −228F to −48F (−308C to −208C), the viscosity of the sealant increases and the sealant will flow more slowly. In such temperatures, bring the sealant into the vehicle to warm it up before use. . When mending the tire, if the air pressure gauge is hard to read, turn the compressor switch off once to get an accurate reading. 5. While filling the tire with air, attach the speed limit label on the position shown in the illustration. WARNING Do not attach the speed limit label in a position where the label hides the warning lamp or on the steering wheel. It may interfere with the normal operation of the airbag and lead to a critical failure. 6. Turn the air compressor power switch off when the air pressure reaches the green zone of the air gauge. Remove the power plug from the accessory power socket. Remove the hose after filling the tire with 17 18 air and fasten the valve cap. Connect the hose of the bottle to the valve of the bottle in a circular fashion to avoid leakage of the remaining sealant. CAUTION The sealant may stain clothing. 7. Stow the kit back in the vehicle and drive your vehicle immediately for 10 minutes or 3 miles (5 km). WARNING . Drive carefully. Do not exceed 50 mph (80 km/h). Driving faster than that can result in the vehicle shaking. . Do not use tire chains on a sealed tire. . Do not tow a trailer. . If heavy vibrations, unsteady steering behavior or noises occur while driving, reduce your speed and drive with caution to a location where it is safe for you to stop the vehicle. Recheck the tire and its pressure. If the tire pressure is in the red zone of the air gauge or if there are any cracks, bumps or similar tire damage visible, temporary repairs cannot be performed with the repair kit. We recommend that you consult with your SUBARU dealer or road service provider. 8. After driving for 10 minutes or 3 miles (5 km), whichever comes first, stop the vehicle in a safe place to recheck the air pressure (see step 4). If necessary, fill the tire with air to the appropriate air pressure again and drive carefully to the nearest SUBARU dealer for tire, valve stem and sealant bottle replacement. NOTE Connect the air compressor only to the tire valve. CAUTION . If the air pressure is in red zone of the air gauge, the kit did not successfully seal the puncture. In this case, stop driving and contact your SUBARU dealer for help. . Do not drive your vehicle with the sealed tire for more than 125 miles (200 km). Failure to replace the valve stem may result in air leakage at the valve stem. Before the tire is removed from the rim, inform your SUBARU dealer or other tire dealer that the tire contains sealant. CAUTION The sealant bottle and speed limit label need to be replaced after using the flat tire repair kit.

It should be performed only on a closed, supervised course by drivers with adequate skill and experience. High performance driving should never be performed on public roads. When driving on public roads, always obey posted speed limits and other applicable laws. Failure to follow these warnings, and the steps outlined below, may result in serious injury or death. CAUTION High performance driving presents a high risk of damage to your vehicle and its component parts. It requires additional maintenance and vehicle preparation, and should be performed only by drivers with adequate skill and experience. Failure to follow the steps outlined below may result in significant damage to your vehicle. Additionally, your vehicle warranties do not cover damage that results from high performance driving. Precautions for high performance driving are listed as follows. However, the listed precautions are minimum requirements and additional measures may be necessary to ensure safety. It is the owner’s responsibility to maintain the vehicle in its optimum condition and acknowledge the risk of high performance driving. & Before driving S00X101 1. Inspect the remaining brake pad thickness and replace them if they are 6 mm or less. Consult your SUBARU dealer for replacement. 2. Prior to high performance driving, check the brake related parts. If changing the brake fluid to a high performance brake fluid, use an Ethylene glycol based brake fluid equivalent to genuine brake fluid. Do not use silicone based fluids. When a high performance fluid is used, check the brake related parts and perform an inspection frequently, including the brake hoses. These parts may be exposed to heat from high performance driving. Change the fluid to genuine DOT3 fluid or DOT4 fluid after high performance driving. 3. If new brake pads have been fitted, prior to high performance driving, perform a brake quenching to achieve immediate and constant deceleration when braking at high speeds. Regarding brake quenching, refer to the following steps. Drive the vehicle for approximately 50 miles (80 km) while avoiding excessive acceleration and sudden braking. Then drive the vehicle for approximately 50 more miles (80 km) to burnish the brake pads. To burnish the brake pads, gradually increase the vehicle speed and apply strong braking. 4. The power steering fluid level is recommended to be maintained at “HOT MIN” due to the thermal expansion of the fluid when heated up. Refer to the vehicle Owner’s Manual for details. 5. To improve engine cooling in high ambient temperatures, the undercover may be removed to increase the engine cooling efficiency. Consult your SUBARU dealer for details. 6. Make sure that the cooling vents/ ducts, intercooler and the radiator are free of blockage. 7. When parking a vehicle under the blazing sun, the water in the intercooler water spray tank will be very high in temperature. Filling up the intercooler water spray tank with cold water prior to using the intercooler water spray may help to increase the intercooler performance. Refer to “Refilling the intercooler water spray tank” FP6. 8. Remove all unsecured cargo from the vehicle’s interior, including the floor mats. 9. Remove the center cap from the alloy wheel to prevent discoloration and warpage from heat. 10. Check that the battery is securely fixed before driving. 11. Check that the tires have enough tread depth and are free of damage. 12. Prior to high performance driving, check that the tire pressures are the appropriate values that allow for the increasing temperature of the tires. & During driving S00X102 1. Tire pressure becomes high during high performance driving due to the increase in tire temperature. Adjust the tire pressure frequently in between drivings. 2. Before driving at high speeds, drive moderately to check the vehicle conditions. 3. Brake pedal travel may increase during high performance driving. In this case, decelerate the vehicle speed immediately and keep enough distance from, the vehicle in front then perform a cooling run. 4. It is crucial to sufficiently cool down the vehicle after high performance driving. Do not stop and park the vehicle immediately after high performance driving. Perform a cooling run and make sure the hood is opened when stopped. & After driving S00X103 1. After high performance driving, inspect the vehicle condition, such as wheel nut tightening torque, tire wear, brake wear, tire pressure and fluid levels, to ensure safety. Inspection prior to high performance driving is also recommended. 2. If the undercover, floor mats and other parts are removed temporarily prior to high performance driving, do not forget to reinstall them. 3. Cracks may form on the surface of the disc rotors due to extreme braking from high performance driving. Depending on the severity of the cracks, the disc rotors and brake pads may need to be replaced. Consult your SUBARU dealer for replacement. 31
