WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Battery acid and battery acid fumes are extremely dangerous and can cause server burns and explosion. To help reduce the risk of personal injury;
- Wear appropriate goggles and protective clothing.
- Always properly ventilate the area where the service is being performed.
- Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces.
- To avoid arcing, remove the negative (-) battery cable first and attach the negative (-) battery cable last.
- If acid contacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

To avoid the risk of personal injury, do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove the radiator cap by turning it all the way.

CAUTION: To avoid possible engine and system damage or performance issues:

Brush away all dirt and debris from the area prior to opening any fuel, air intake, exhaust, cooling, aftertreatment or other engine system.
To avoid contamination, any open engine system ports must be closed immediately with clean care caps or an appropriate covering.
Do not allow any debris to fall into the engine.
Do not allow any chemical cleaners to enter the engine or any open systems during the cleaning process.
