The "Drive Unavailable, Temp. Too High" message on your COMAND system indicates that your vehicle's transmission temperature is too high and needs to cool down before it can be used again. This can be caused by a number of factors, including towing a heavy load, driving in high temperatures or stop-and-go traffic, or a malfunctioning cooling system.
Here are some steps you can take to address this issue:
Pull over and turn off the engine: If you receive this message while driving, pull over to a safe location and turn off the engine. Allow the vehicle to cool down for at least 30 minutes before attempting to drive it again.
Check the coolant level: If your vehicle's coolant level is low, it can cause the engine to overheat and trigger the "Drive Unavailable, Temp. Too High" message. Check the coolant level and add more if necessary.
Inspect the cooling system: The cooling system consists of several components, including the radiator, thermostat, water pump, and hoses. If any of these components are malfunctioning or damaged, they can cause the engine to overheat. Have a certified mechanic or dealership inspect the cooling system to identify and fix any issues.
Avoid towing heavy loads: Towing a heavy load can put additional strain on the engine and cause it to overheat. If you need to tow a load, make sure it is within the vehicle's towing capacity and avoid driving in hot or hilly conditions.
Service the transmission: Regular transmission service, such as fluid changes, can help ensure that the transmission is functioning properly and prevent overheating.
It is important to address this issue promptly to prevent damage to the transmission and ensure the safe operation of your vehicle. If the issue persists, take your vehicle to a certified mechanic or dealership for further diagnosis and repair.
The "Drive Unavailable, Temp. Too High" message on your COMAND system can be caused by a number of issues related to the vehicle's transmission or cooling system. Here are some steps you can take to help address the issue:
Stop the vehicle: If the "Drive Unavailable, Temp. Too High" message appears while driving, safely stop the vehicle as soon as possible to prevent damage to the transmission.
Allow the vehicle to cool down: Turn off the engine and allow the vehicle to cool down for at least 30 minutes. This will help lower the temperature of the transmission and cooling system.
Check the coolant level: The vehicle's cooling system should be inspected to ensure the coolant level is at the recommended level. If it is low, refill it with the proper coolant.
Check for leaks: The cooling system should also be checked for any leaks that could be causing a loss of coolant. If any leaks are found, they should be repaired.
Check the transmission fluid level: The transmission fluid level should also be checked to ensure it is at the correct level. Low transmission fluid levels can cause the transmission to overheat.
Inspect the transmission cooler: The transmission cooler is responsible for cooling the transmission fluid. It should be inspected to ensure it is not blocked or damaged, preventing the transmission from cooling properly.
Inspect the radiator: The radiator is responsible for cooling the engine coolant. It should be inspected to ensure it is not blocked or damaged, preventing the engine from cooling properly.
Inspect the transmission: If the above steps do not resolve the issue, there may be an internal issue with the transmission that is causing it to overheat. A certified mechanic or dealership should inspect the transmission for any issues and perform any necessary repairs.
It is important to address the "Drive Unavailable, Temp. Too High" message promptly to prevent damage to the transmission and ensure safe operation of the vehicle. If the issue persists, it is recommended to take your vehicle to a certified mechanic or dealership for further diagnosis and repair.
