Toyota Highlander 2007 Owner's Manual

The 2007 Toyota Highlander typically requires 5W-30 synthetic oil. The oil capacity with a filter change is approximately 5 quarts for the 4-cylinder engine and 6 quarts for the V6 engine.
To reset the maintenance light, turn the ignition switch to the 'ON' position, set the odometer to 'ODO' mode, turn off the ignition, press and hold the odometer reset button, then turn the ignition back to 'ON' without starting the engine. Hold the button until the light turns off.
Common causes include a loose gas cap, faulty oxygen sensor, failing catalytic converter, malfunctioning mass airflow sensor, or spark plug/ignition coil issues. It's recommended to use an OBD-II scanner to diagnose the specific issue.
To replace the cabin air filter, open the glove box, push in the sides to release the stops, remove the filter cover behind the glove box, and slide out the old filter. Insert the new filter with airflow arrows pointing in the correct direction, replace the cover, and close the glove box.
The 2007 Toyota Highlander has a towing capacity of up to 3,500 pounds when properly equipped with the optional towing package.
First, check if the A/C system has sufficient refrigerant. Inspect the A/C compressor, belts, and fuses. Ensure the cabin air filter is clean. If issues persist, it may require a professional diagnostic to check for leaks or compressor faults.
The recommended tire pressure for the 2007 Toyota Highlander is typically 30 psi for both front and rear tires. However, always refer to the placard on the driver's side door jamb for the most accurate information.
To replace a headlight bulb, open the hood, locate the back of the headlight assembly, disconnect the power connector, remove the rubber cover, release the bulb retaining clip, and then replace the old bulb with a new one. Reassemble in reverse order.
Maintain regular maintenance such as oil changes and air filter replacements, ensure tires are properly inflated, avoid excessive idling, drive at a consistent speed, and reduce unnecessary weight in the vehicle.
Warm up the engine, park on a level surface, and keep the engine running. Locate the transmission dipstick, remove it, wipe clean, reinsert fully, then remove again to check the fluid level. The fluid should be between the 'Full' and 'Add' marks.
