nStarting the engine when the battery is discharged
The engine cannot be started by push-starting.
nTo prevent battery discharge
lTurn off the headlights and the audio system while the engine is off.
lTurn off any unnecessary electrical components when the vehicle is running at a
low speed for an extended period, such as in heavy traffic.
nWhen the battery is removed or discharged
The power back door must be initialized. (→P. 6 3 0 )
Connect a negative cable clamp to the negative (-) battery terminal
on the second vehicle
Connect the clamp at the other end of the negative cable to a solid,
stationary, unpainted metallic point away from the battery and any
moving parts, as shown in the illustration.
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain that level for approximately 5 min-
utes to recharge the battery of your vehicle.
Open and close any of the doors with the “ENGINE START
STOP” switch off.
Maintain the engine speed of the second vehicle and start the
engine of your vehicle by turning the “ENGINE START STOP”
switch to IGNITION ON mode.
Once the vehicle’s engine has started, remove the jumper

lDo not allow the “+” and “-” terminals of the jumper cables to come into contact
with each other.
lDo not smoke, use matches, cigarette lighters or allow open flame near the bat-
tery.
nBattery precautions
The battery contains poisonous and corrosive acidic electrolyte, while related parts

Fuel information
nFuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only
accommodates the special nozzle on unleaded fuel pumps.
nIf your engine knocks
lConsult your Lexus dealer.
lYou may occasionally notice light knocking for a short time while accelerating
or driving uphill. This is normal and there is no need for concern.
nGasoline quality
In very few cases, driveability problems may be caused by the brand of gasoline you
are using. If driveability problems persist, try changing the brand of gasoline. If this
does not correct the problem, consult your Lexus dealer.
Your vehicle must use only unleaded gasoline.
Premium unleaded gasoline with an octane rating of 91 (Research Octane
Number 96) or higher required for optimum engine performance. If 91
octane cannot be obtained, you may use unleaded gasoline with an octane
rating as low as 87 (Research Octane Number 91). Use of unleaded gaso-
line with an octane rating lower than 91 may result in engine knocking. Per-
sistent knocking can lead to engine damage and should be corrected by
refueling with higher octane unleaded gasoline.
At minimum, the gasoline you use should meet the specifications of
ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.
