5-2. Steps to take in an emergency
■If the electronic engine control system warning light comes on while driving
First check the following:
●Is your vehicle low on gas?
If it is, refuel the vehicle immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after taking several driving trips.
If the light does not go off even after several trips, contact your Lexus dealer as soon
as possible.
■Front passenger detection sensor and passenger seat belt reminder
●If luggage is placed on the front passenger seat, the front passenger detection
sensor may cause the warning light to flash, even if a passenger is not sitting in
the seat.
●If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.

Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity
●5W oils are for use in areas where the ambient temperature is -3F (-25C) or
above. "10W" oils are for areas where the ambient temperature is -4
F (-20C)
or above. Oils with smaller figures are better for engine starting in cold weather
and fuel efficiency.
● XX-30 indicates oil viscosity. Oils with higher numbers have better sta-
bility at higher temperatures and are good for high-speed driving.
