Nissan Altima (L34) 2019-2024 Owners Manual: All-Wheel Drive (AWD) (if so equipped)

If any malfunction occurs in the AWD system while the engine is running, messages are displayed in the meter.

If the AWD error warning message is displayed, there may be a malfunction in the AWD system. Reduce vehicle speed and have your vehicle checked. It is recommended that you visit a NISSAN dealer as soon as possible.

The AWD high temperature message may be displayed while trying to free a stuck vehicle due to increased oil temperature.

The driving mode may change to 2-wheel drive. If this message is displayed, stop the vehicle with the engine idling, as soon as it is safe to do so. Then if the message turns off, you can continue driving.

The tire size message may be displayed if there is a large difference between the diameters of front and rear wheels. Pull off the road in a safe area, with the engine idling. Check that all tire sizes are the same, that the tire pressure is correct and that the tires are not excessively worn.

If any warning messages continue to be displayed, have your vehicle checked. It is recommended that you visit a NISSAN dealer as soon as possible.

WARNING

• Do not drive beyond the performance capability of the tires. Accelerating quickly, sharp steering maneuvers or sudden braking may cause loss of control, even with AWD engaged.
• For AWD equipped vehicles, do not attempt to raise two wheels off the ground and shift the transmission to any drive or reverse position with the engine running. Doing so may result in drivetrain damage or unexpected vehicle movement which could result in serious personal injury or vehicle damage.
• Do not attempt to test an AWD equipped vehicle on a 2-wheel dynamometer (such as the dynamometers used by some states for emissions testing) or similar equipment even if the other two wheels are raised off the ground. Make sure that you inform the test facility personnel that your vehicle is equipped with AWD before it is placed on a dynamometer. Using the wrong test equipment may result in drivetrain damage or unexpected vehicle movement which could result in serious personal injury or vehicle damage.

CAUTION

• Do not operate the engine on a free roller when any of the wheels are raised.
• If you use the free roller, rotate four wheels with the same speed without raising any wheels.
• If an AWD warning message is displayed while driving there may be a malfunction in the AWD system. Reduce the vehicle speed immediately and have your vehicle checked. It is recommended that you visit a NISSAN dealer as soon as possible.
• The powertrain may be damaged if you continue driving when the AWD temperature or tire size incorrect messages are displayed
• If the AWD high temperature message is displayed while you are driving, pull off the road in a safe area, and idle the engine. The driving mode will change to 2WD to prevent the AWD system from malfunctioning.

  If the warning message turns off, you can drive again.

• If the tire size incorrect message is displayed while you are driving, pull off the road in a safe area with the engine idling. Check that all tire sizes are the same, that the tire pressure is correct and that the tires are not excessively worn.
• If a warning message continues to be displayed after the above operations, have your vehicle checked as soon as possible. It is recommended that you visit a NISSAN dealer for this service.
