  2. Holding a rag under the end, pull the dipstick out.
     
  3. Wipe the dipstick clean.
  4. Reinsert the dipstick fully.
  5. Holding a rag under the end, pull the dipstick out and check the oil level.
     1. Low
     2. Normal
     3. Excessive
     4. The shape of the dipstick may differ depending on the type of vehicle or engine.
        
  6. Wipe the dipstick and reinsert it fully.

Adding engine oil
If the oil level is below or near the low level mark, add engine oil of the same type as already in the engine.

Make sure to check the oil type and prepare the items needed before adding oil.

WARNING

• Used engine oil
  • Used engine oil contains potentially harmful contaminants which may cause skin disorders such as inflammation or skin cancer, so care should be taken to avoid prolonged and repeated contact. To remove used engine oil from your skin, wash thoroughly with soap and water.
  • Dispose of used oil and filters only in a safe and acceptable manner. Do not dispose of used oil and filters in household trash, in sewers or onto the ground. Call your Lexus dealer, service station or auto parts store for information concerning recycling or disposal.
  • Do not leave used engine oil within the reach of children.

NOTICE

• To prevent serious engine damage
  Check the oil level on regular basis.
• When replacing the engine oil
  • Be careful not to spill engine oil on the vehicle components.
  • Avoid overfilling, or the engine could be damaged.
  • Check the oil level on the dipstick every time you refill the vehicle.
  • Be sure the engine oil filler cap is properly tightened.

Engine coolant
The coolant level is satisfactory if it is between the “F” and “L” lines on the reservoir when the engine is cold.

1. Reservoir cap
2. “F”
3. “L”

If the level is on or below the “L” line, add coolant up to the “F” line.

Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high-quality ethylene glycol-based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology.

• U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50 % coolant and 50 % deionized water. (Minimum temperature: -31F [-35C])
• Canada: “Toyota Super Long Life Coolant” is a mixture of 55 % coolant and 45 % deionized water. (Minimum temperature: -44F [-42C])

For more details about engine coolant, contact your Lexus dealer.

If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, radiator cap, drain cock and water pump. If you cannot find a leak, have your Lexus dealer test the cap and check for leaks in the cooling system.

WARNING

• When the engine is hot
  Do not remove the radiator cap. The cooling system may be under pressure and may spray hot coolant if the cap is removed, causing serious injuries, such as burns.

NOTICE

• When adding coolant
  Coolant is neither plain water nor straight antifreeze. The correct mixture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be sure to read the antifreeze or coolant label.
• If you spill coolant
  Be sure to wash it off with water to prevent it from damage to parts or paint.

Radiator and condenser
Check the radiator and condenser and clear any foreign objects.
If either of the above parts is extremely dirty or you are not sure of their condition, have your vehicle checked by your Lexus dealer.

WARNING

• When the engine is hot
  Do not touch the radiator or condenser as they may be hot and cause serious injuries, such as burns.

Brake fluid

• Checking fluid level
  The brake fluid level should be between the “MAX” and “MIN” lines on the tank.
  
• Adding fluid
  Make sure to check the fluid type and prepare the necessary item.
• Brake fluid can absorb moisture from the air
  Excess moisture in the fluid can cause a dangerous loss of braking efficiency. Use only newly opened brake fluid.

WARNING

• When filling the reservoir
  Take care because brake fluid can harm your hands or eyes and damage painted surfaces. If fluid gets on your eyes, flush the affected area with clean water immediately. If you still experience discomfort, see a doctor.

NOTICE

• If the fluid level is low or high
  It is normal for the brake fluid level to go down slightly as the brake pads wear or when the fluid level in the accumulator is high. If the reservoir needs frequent refilling, it may indicate a serious problem.

Power steering fluid

Fluid level
The fluid level should be within the appropriate range.

1. Full (when cold)
2. Add fluid (when cold)
3. Full (when hot)
4. Add fluid (when hot)

  (Fluid temperature, 140F – 175F [60C – 80C]).
• Cold: The engine has not been run for about 5 hours.
  (Room temperature, 50F – 85F [10C – 30C]).

Checking the fluid level
Make sure to check the fluid type and prepare the necessary items.

1. Clean all dirt off the reservoir.
2. Remove the cap by turning it counterclockwise.
3. Wipe the dipstick clean.
4. Reinstall the cap and remove it again.
5. Check the fluid level.

Battery

Check the battery as follows.

• Battery exterior
  Make sure that the battery terminals are not corroded and that there are no loose connections, cracks, or loose clamps.
  1. Terminals
  2. Hold-down clamp
     
• Before recharging
  When recharging, the battery produces hydrogen gas which is flammable and explosive. Therefore, observe the following before recharging:
  • If recharging with the battery installed on the vehicle, be sure to disconnect the ground cable.
  • Make sure the power switch on the charger is off when connecting and disconnecting the charger cables to the battery.
• After recharging/reconnecting the battery
  The engine may not start. Follow the procedure below to initialize the system. Shift the shift lever to P Open and close any of the doors. Restart the engine.
  • Unlocking the doors using the smart access system with push-button start may not be possible immediately after reconnecting the battery. If this happens, use the wireless remote control or the mechanical key to lock/unlock the doors.
  • Start the engine with the engine switch in ACCESSORY mode. The engine may not start with the engine switch turned off. However, the engine will operate normally from the second attempt.
  • The engine switch mode is recorded by the vehicle.
    If the battery is reconnected, the vehicle will return the engine switch mode to the status it was in before the battery was disconnected. Make sure to turn off the engine before disconnect the battery. Take extra care when connecting the battery if the engine switch mode prior to discharge is unknown.

If the system will not start even after multiple attempts, contact your Lexus dealer.

  Do not add washer fluid when the engine is hot or running as washer fluid contains alcohol and may catch fire if spilled on the engine etc.

NOTICE

• Do not use any fluid other than washer fluid
  Do not use soapy water or engine antifreeze instead of washer fluid. Doing so may cause streaking on the vehicle’s painted surfaces, as well as damaging the pump leading to problems of the washer fluid not spraying.
