The rear climate control switches are located in the rear
armrest.
The rear climate control seat has two switches: one
marked “L” (for the rear left seat) and the other marked
“R” (for the rear right seat).
The ignition switch must be in the “ON” position.
The rear climate control seat has three modes: air at room
temperature, cool air and warm air. To use the rear seat climate control, push the knob and
turn the knob. The indicator light comes on.
To feed air at room temperature,
turn the knob to the gray
zone.
To feed cool air, turn the knob counterclockwise and set the
knob in the blue zone. Three setting levels are available.
To feed warm air, turn the knob clockwise and set the knob in
the red zone. Three setting levels are available. When you
push and turn the knob to the red zone, the seat heater turns
on first and then the rear climate control operates to feed warm
air.
After the switch is turned on, it takes several minutes until you
feel warm or cool.
To disable this function, push the knob again. The indicator
light goes off.
If you turn off the ignition switch without turning off the rear
climate control seat, the rear climate control seat does not turn
on with the ignition on.

FUEL GAUGE
13L062d
Low fuel level warning light
The gauge indicates the approximate quantity of fuel
remaining in the tank when the ignition switch is on.
It is a good idea to keep the tank over 1/4 full.
If the fuel level approaches “E” or the low fuel level warning light\
comes on, fill the fuel tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the fuel gauge needle may fluctuate or the low fuel level
warning light may come on earlier than usual.
If the fuel tank is completely empty, the malfunction indicator
lamp comes on. Fill the fuel tank immediately.
The indicator lamp goes off after driving several times. If the
indicator lamp does not go off, contact your Lexus dealer as
soon as possible. See the inner back cover for fuel capacity and recommended
fuel selection.
ENGINE COOLANT
TEMPERATURE GAUGE
13L151
 Normal range
The gauge indicates the engine coolant temperature when
the ignition switch is on. The engine operating
temperature will vary with changes in weather and engine
load.
If the needle points to the red zone or higher, stop your vehicle
and allow the engine to cool.
Your vehicle may overheat during severe operating conditions,
such as:
 Driving up a long hill on a hot day.
 Reducing speed or stopping after high speed driving.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
81

Idling for a long period with the air conditioning on in
stop−and−go traffic.
 Towing a trailer.
NOTICE
Do not remove the thermostat in the engine cooling
system as this may cause the engine to overheat. The
thermostat is designed to control the flow of coolant
to keep the temperature of the engine within the
specified operating range.
 Do not continue driving with an overheated engine.
See “If your vehicle overheats” on page 404.
TACHOMETER
13L144
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine overrevving.
Driving with the engine running too fast causes excessive
engine wear and poor fuel economy. Remember, in most
cases the slower the engine speed, the greater the fuel
economy.
NOTICE
Do not let the indicator needle get into the red zone. This
may cause severe engine damage.
