3. Exhaust Emission Control System

The exhaust emission control system is a highly effective system that controls exhaust emissions while maintaining good vehicle performance.

When the engine starts or fails to start, excessive attempts to restart the engine may cause damage to the exhaust system.

Vehicle Modifications

• This vehicle must not be modified. Modification of your vehicle may affect its performance, safety, or durability, and may even violate safety and emissions regulations. In addition, damage or performance problems resulting from any modifications are not covered by the warranty.
• Use of unauthorized electronic devices may cause the vehicle to malfunction, wire damage, battery discharge, and fire. For your safety, do not use unauthorized electronic devices.

Engine Exhaust Precautions (Carbon Monoxide)

Carbon monoxide may be present in other exhaust gases. If you smell exhaust fumes of any kind in your vehicle, drive with all windows fully open. Have your vehicle inspected and repaired immediately.

WARNING

Engine exhaust contains carbon monoxide (CO). Although colorless and odorless, it is dangerous and can be fatal if inhaled. Follow the instructions on this page to avoid carbon monoxide poisoning.

WARNING

CALIFORNIA PROPOSITION 65 WARNING

Engine exhaust, and some vehicle components and parts, including interior trim components, contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. In addition, some fluids contained in vehicles and certain component wear products contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

• Do not operate the engine in enclosed or confined areas (such as garages) any longer than necessary to enter or exit the area.
• When the vehicle is stopped in an open area for more than a short time with the engine running, adjust the ventilation system (if necessary) to draw outside air into the vehicle.
• Never sit in a parked or stopped vehicle for a long period with the engine running.
• When the engine stalls or fails to start, excessive attempts to restart the engine may cause damage to the emission control system.

Precautions for Operating Catalytic Converters (if equipped)

WARNING

• The exhaust system and catalytic converter become very hot during and immediately after engine operation. To avoid SERIOUS INJURY or DEATH.
• Do not park, stop, or drive the vehicle over or near flammable materials such as grass, vegetation, paper, leaves, etc. The hot exhaust system may ignite flammable materials under the vehicle.
• Keep away from the exhaust system and catalytic converter, otherwise you may get burned. Also, do not remove heat shields around the exhaust system, do not seal the underbody, and do not apply corrosion-proofing coating to the vehicle. Under certain conditions, this may create a fire hazard.

Your vehicle is equipped with a catalytic converter.

To prevent damage to the catalytic converter and your vehicle, observe the following precautions:

CAUTION

• Use only UNLEADED FUEL for gasoline engines.
• Do not operate the vehicle if there are signs of engine malfunction, such as misfiring or noticeable loss of performance.
• Do not misuse or abuse the engine. Examples of misuse include coasting downhill in gear with the engine off.
• Do not run the engine at high idle speed for a long time (5 minutes or more).
• Do not modify or tamper with any part of the engine or the emission control system. All inspections and adjustments must be performed by an authorized HYUNDAI dealer.
• Avoid driving with very low fuel. If you run out of gasoline, it may cause engine misfire and overheating of the catalytic converter.
