7-2. Steps to take in an emergency
■ When the electronic key does not work
properly
● Make sure that the smart access system
with push-button start has not been deac-
tivated in the customization setting. If it is
off, turn the function on.
(Customizable features: P.680)
● Check if battery-saving mode is set. If it is
set, cancel the function. (P.128)
● The electronic key function may have
stopped. (P.129)
Use the mechanical key (P.105) in
order to perform the following opera-
tions.
● Using the lever to open the fuel filler
door may not allow for an adequate
reduction in fuel tank pressure before
refueling. To prevent fuel from spilling
out, turn the cap slowly when remov-
ing it.
● During refueling, fuel may spill out
from the filler opening due to air being
discharged from inside the fuel tank.
Therefore, fill the fuel tank carefully
and slowly.
If the electronic key does not
operate properly
If communication between the
electronic key and vehicle is inter-
rupted (P.129) or the electronic
key cannot be used because the
battery is depleted, the smart
access system with push-button
start and wireless remote control
cannot be used. In such cases, the
doors can be opened and the hybrid
system can be started by following
the procedure below.
■ In case of a smart access system with
push-button start malfunction, or
other key related problems
Take your vehicle with all the electronic
keys provided with your vehicle (includ-
ing the card key) to your Lexus dealer.
