To connect your smartphone via Bluetooth, go to the 'Settings' menu on the infotainment system, select 'Bluetooth', then 'Pair New Device'. Make sure Bluetooth is enabled on your smartphone and select the CT5 from the available devices list. Confirm the passkey on both devices if prompted.
The Cadillac CT5 2021 typically requires SAE 5W-30 full synthetic motor oil. Always check the owner's manual for the specific oil specifications and recommendations.
To reset the TPMS, turn the ignition to the 'On' position without starting the engine. Press and hold the TPMS reset button located under the steering column until the TPMS indicator blinks three times. Then, start the vehicle and let it run for 20 minutes to reset the sensor.
The recommended maintenance schedule includes an oil change every 7,500 miles or 12 months, tire rotation every 7,500 miles, and replacing the air filter every 22,500 miles. Brake fluid should be changed every 45,000 miles. Always refer to the owner’s manual for detailed maintenance intervals.
To update the navigation system, visit the Cadillac website to check for available updates. You may download the update onto a USB drive and use the vehicle's USB port to install it, following on-screen instructions. Alternatively, some updates may be available via over-the-air updates if your vehicle is equipped with this capability.
To improve fuel efficiency, maintain regular service schedules, ensure tires are properly inflated, avoid excessive idling, and drive at steady speeds. Reducing weight and using cruise control on highways can also help save fuel.
If the engine overheats, turn off the air conditioning and turn on the heater to help dissipate heat. Pull over safely and turn off the engine, allowing it to cool. Check coolant levels once the engine is cool. If necessary, add coolant and inspect for leaks. Seek professional help if the problem persists.
To replace the cabin air filter, open the glove box and remove any contents. Detach the dampener arm and lower the glove box completely. The cabin air filter compartment is located behind the glove box. Open the compartment, remove the old filter, and insert a new one, ensuring proper orientation. Reassemble the glove box.
To set up memory seats, adjust the seat, mirrors, and steering column to your preference. Press and hold the 'SET' button on the driver's door until you hear a beep. Immediately press and hold one of the memory buttons (1 or 2) until you hear a second beep, indicating the position has been saved.
To jump-start the CT5, park a vehicle with a good battery close to yours. Connect the positive cable to the positive terminal of the dead battery first, then to the positive terminal of the good battery. Connect the negative cable to the negative terminal of the good battery, then to an unpainted metal surface on the engine block of the CT5. Start the assisting vehicle, then your CT5. Once started, disconnect the cables in reverse order.
