2024 Subaru Crosstrek Owner’s Manual

 

Fuel

CAUTION

• Use of a fuel which is low in quality or use of an inappropriate fuel additive may cause damage to the engine and/or fuel system.
• Some gas stations, particularly those in high-altitude areas, offer fuels posted as regular octane gasoline with an octane rating below 87 AKI (90 RON). Use of those fuels are not recommended.

Fuel Requirements
The engine is designed to operate using unleaded gasoline with an octane rating of 87 AKI (90 RON) or higher.

Fuel octane rating
Using gasoline with a lower octane rating can cause persistent and heavy knocking, which can damage the engine. Do not be concerned if your vehicle sometimes knocks lightly when you drive up a hill or when you accelerate. Contact your SUBARU dealer if you use a fuel with the specified octane rating and your vehicle knocks heavily or persistently.
RON This octane rating is the Research Octane Number.
AKI This octane rating is the average of the Research Octane and Motor Octane numbers and is commonly referred to as the Anti Knock Index (AKI).

Unleaded gasoline
The neck of the fuel filler pipe is designed to accept only an unleaded gasoline filler nozzle. Under no circumstances should leaded gasoline be used because it will damage the emission control system and may impair driveability and fuel economy.

Reformulated gasoline
SUBARU supports the use of reformulated gasoline when available. Reformulated gasoline has been blended to burn more cleanly and reduce vehicle emissions.

MMT
Some gasoline contains an octane-enhan-cing additive called MMT (Methylcyclopentadienyl Manganese Tricarbonyl). If you use such fuels, your emission control system performance may deteriorate and the CHECK ENGINE warning light/malfunction indicator light may turn on. If this happens, return to your authorized SUBARU Dealer for service. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by your warranty.

Gasoline for cleaner air
Your use of gasoline with detergent additives will help prevent deposits from forming in your engine and fuel system. This helps keep your engine in tune and your emission control system working properly and is a way of doing your part for cleaner air. If you continuously use high-quality fuel with the proper detergent and other additives, you should never need to add any fuel system cleaning agents to your fuel tank.
Many gasolines are now blended with materials called oxygenates. Use of these fuels can also help keep the air cleaner. Oxygenated blend fuels, such as ethanol (ethyl or grain alcohol) may be used in your vehicle but should contain no more than 15% ethanol for the proper operation of your SUBARU.
Do not use any gasoline that contains more than 15% ethanol, including from any pump labelled E30, E50 or E85 (which are only some examples of fuel containing more than 15% ethanol).

In addition, some gasoline suppliers are now producing reformulated types of gasoline, which are designed to reduce vehicle emissions. SUBARU approves the use of reformulated gasoline.
If you are not sure what the fuel contains, you should ask your service station operators if their gasoline contains detergents and oxygenates and if they have been reformulated to reduce vehicle emis-sions.
As additional guidance, only use fuels suited for your vehicle as explained in the following.

• Fuel should be unleaded and have an octane rating no lower than that specified in this manual.
• Methanol (methyl or wood alcohol) is sometimes mixed with unleaded gasoline. Methanol can be used in your vehicle ONLY if it does not exceed 5% of the fuel mixture AND if it is accompanied by sufficient quantities of the proper cosolvents and corrosion inhibitors required to prevent damage to the fuel system. Do not use fuel containing methanol EXCEPT under these condi-tions.
• If undesirable driveability problems are experienced and you suspect they may be fuel-related, try a different brand of gasoline before seeking service at your SUBARU dealer.
• Fuel system damage or driveability problems which result from the use of improper fuel are not covered under the SUBARU Limited Warranty.

Fuel Filler Lid and Cap
Locations of the fuel filler lid

Refuelling
Only one person should be involved in refuelling. Do not allow others to approach the area of the vehicle near the fuel filler pipe while refuelling is in progress.
Be sure to observe any other precautions that are posted at the service station.

1. Stop the vehicle and turn the ignition switch to the “LOCK”/ “OFF” position and turn off all the other electrical components.
2. 2. To unlock the fuel filler lid, perform one of the operations below.
   – Press the “Lock” button on the key fob.
   – Press the unlock side of the power door locking switch.
   3. Push the rear side of the fuel filler lid.
   4. The fuel filler lid opens automatically. Open it further by hand.

WARNING
Before opening the fuel filler cap, first touch the vehicle body or a metal portion of the fuel pump or similar object to discharge any sta-tic electricity that may be present on your body. If your body is carrying an electrostatic charge, there is a possibility that an electric spark could ignite the fuel, which could burn you. To avoid acquiring a new static electric charge, do not get back into the vehicle while refuelling is in progress.

Preparing to Drive

You should perform the following checks and adjustments every day before you start driving.

1. Check that all windows, mirrors, and lights are clean and unobstructed.
2. Check the appearance and condition of the tires. Also check tires for proper inflation.
3. Look under the vehicle for any sign of leaks.
4. Check that no small animals enter the engine compartment.
5. Check that the hood and rear gate are fully closed.
6. Check the adjustment of the seat.
7. Check the adjustment of the inside and outside mirrors.
8. Fasten your seatbelt. Check that your passengers have fastened their seatbelts.
9. Check the operation of the warning and indicator lights when the ignition switch is turned to the “ON” position.
10. Check the gauges, indicator and warning lights after starting the engine.

CAUTION
Trapping small animals in the cooling fan and drive belt may result in a malfunction. Check that no small animal enters the engine compartment and under the vehicle before starting the engine.

NOTE

• Engine oil, engine coolant, brake fluid, washer fluid and other fluid levels should be checked daily, weekly or at fuel stops.
• When towing a trailer, refer to “Trailer Hitch (Dealer Option)”

7-4. Starting and Stopping the Engine (Models without Push-Button Ignition Switch)

General Precautions When Starting/Stopping Engine

WARNING

•  Never start the engine from out- side the vehicle (except when using the remote engine start system). It may result in an acci-dent.
• Do not leave the engine running in locations with poor ventilation, such as a garage and indoors. The exhaust gas may enter the vehicle or indoors, and it may result in carbon monoxide poi-soning.
• Do not start the engine near dry foliage, paper, or other flammable substances. The exhaust pipe and exhaust emissions can create a fire hazard at high temperatures.

CAUTION

• If the engine is stopped during driving, the catalyst may overheat and burn.
• When starting the engine, be sure to sit in the driver’s seat (except when using the remote engine start system).

NOTE

• Avoid racing and rapid acceleration immediately after the engine has started.
• After the engine starts, the engine speed will be kept high.
• On rare occasions, it may be difficult to start the engine depending on the fuel used and the driving condition (repeated short trips when the engine is not warmed up sufficiently). In such a case, it is recommended to switch to a different brand of fuel.
• On rare occasions, transient knocking may be heard from the engine when the accelerator is operated rapidly such as a rapid start-up and a rapid acceleration. This is not a malfunction.
• The engine starts more easily when the headlights, air conditioner and rear window defogger are turned off.

Starting Engine
Do not operate the engine starter continuously for more than 10 seconds. If the engine fails to start after operating the engine starter for 5 to 10 seconds, wait for 10 seconds or more before trying again.

NOTE
It may be difficult to start the engine when the battery has been disconnected and reconnected (for maintenance or other purposes). This difficulty is caused by the electronically controlled throttle’s self-diagnosis function. To overcome it, keep the ignition switch in the “ON” position for approximately 10 seconds before starting the engine.
Do not shift the select lever while the engine starter is cranking.

attempt to place the select lever of a moving vehicle into the “P” position.

1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.
3. Shift the select lever to the “P” or “N” position (preferably “P” position). The engine starter will only operate when the select lever is at the “P” or “N” position.
4. Turn the ignition switch to the “ON” position and check the operation of the warning and indicator lights.
5. Turn the ignition switch to the “START” position without depressing the accelerator pedal. Release the key immediately after the engine has started.
   If the engine does not start, perform the following procedure.
   • Turn the ignition switch to the “LOCK” position and wait for at least 10 seconds. After checking that the parking brake is applied, turn the ignition switch to the “START” position while depressing the accelerator pedal slightly (ap-proximately a quarter of the full stroke). Release the accelerator pedal as soon as the engine starts.
   • If this fails to start the engine, turn the ignition switch back to the “LOCK” position and wait for at least 10 seconds. Then fully de-press the accelerator pedal and turn the ignition switch to the “START” position. If the engine starts, quickly release the accelerator pedal.
   • If this fails to start the engine, turn the ignition switch again to the “LOCK” position. After waiting for 10 seconds or longer, turn the ignition switch to the “START” position without depressing the accelerator pedal.
   • If the engine still does not start, contact your nearest SUBARU dealer for assistance.
   • Confirm that all warning and indicator lights have turned off after the engine has started. The fuel injection system automatically lowers the idle speed as the engine warms up.
     While the engine is warming up, make sure that the select lever is at the “P” or “N” position and that the parking brake is applied.
