If You Cannot Increase The Engine Speed; If Your Vehicle Overheats; If Steam Is Coming From Your Engine - Lexus LX 470 Owner's Manual

IN CASE OF AN EMERGENCY
IF YOU CANNOT INCREASE THE
ENGINE SPEED
If the engine speed does not increase with the accelerator
pedal depressed down to about the middle position, there may
be a problem somewhere in your electronic throttle control
system.
At this time, if you depress the accelerator pedal more firmly
and slowly, you can drive your vehicle at low speeds. Have
your vehicle checked by your Lexus dealer as soon as
possible.
Even if the abnormality of the electronic throttle control system
is corrected during low speed driving, the system may not be
recovered until the engine is stopped and the ignition key is
turned to "ACC" or "LOCK" position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.

IF YOUR VEHICLE OVERHEATS

If your engine coolant temperature gauge indicates
overheating, if you experience a loss of power, or if you
hear a loud knocking or pinging noise, the engine has
probably overheated.
When the engine overheats
Pull safely off the road, stop the vehicle and turn on your
emergency flashers. Put the transmission in "P" and apply the
parking brake.
A: If steam is coming from your engine:
Turn off the engine. Leave the hood closed until there is no sign
of steam or coolant. Your engine could have been seriously
damaged already. Call your Lexus dealer for assistance.
CAUTION
To help avoid personal injury, keep the hood closed until
there is no steam. Escaping steam or coolant is sign of
very high pressure.
