Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help improve
fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even when
vehicle operation and driving conditions are the same.
Outside temperature display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 20 km/h [12 mph])
• When the outside temperature has changed suddenly (at the entrance/exit of
a garage, tunnel, etc.)
When “--” or “E” is displayed, the system may be malfunctioning.
Take your vehicle to any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
Customization
Settings (e.g. on/off operation of the ECO lamp) can be changed.
(Customizable features: P. 650)
NOTICE
To prevent damage to the engine and its components
Vehicles with tachometer: Do not let the indicator needle of the tachometer
enter the red zone, which indicates the maximum engine speed.
The engine may be overheating if the high coolant temperature warning light
comes on or flashes. In this case, immediately stop the vehicle in a safe place,
and check the engine after it has cooled completely. (P. 628)

Winter driving tips
Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine/power control unit coolant
•Washer fluid
Have a service technician inspect the condition of the 12-volt battery.
Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match the size
of the tires.
Perform the following according to the driving conditions:
Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away the
water immediately to prevent it from freezing.
To ensure proper operation of the climate control system fan, remove
any snow that has accumulated on the air inlet vents in front of the
windshield.
Check for and remove any excess ice or snow that may have accumu-
lated on the exterior lights, vehicle’s roof, chassis, around the tires or
on the brakes.
Remove any snow or mud from the bottom of your shoes before get-
ting in the vehicle.
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.

Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Lexus dealers or repairers or other duly qual-
ified and equipped professionals. For repairs and services covered by your war-
ranty, please visit an authorized Lexus dealer or repairer, who will use genuine
Lexus parts in repairing any difficulties you may encounter. There can also be
advantages in utilizing authorized Lexus dealers or repairers for non-warranty
repairs and services, as members of the Lexus network will be able to expertly
assist you with any difficulties you may encounter.
Your Lexus dealer or repairer, or another duly qualified and equipped profes-
sional will perform all of the scheduled maintenance on your vehicle reliably and
economically due to their experience with Lexus vehicles.
Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs that
indicate service is needed. Some important clues are:
Engine missing, stumbling or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air condition-
ing system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked imme-
diately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
Vehicle pulls to one side when driven straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches
the floor, vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal (P. 570, 583)
If you notice any of these clues, take your vehicle to any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional as soon as possi-
ble. Your vehicle may need adjustment or repair.

Maintenance and care
WA R N I N G
The engine compartment contains many mechanisms and fluids that may move
suddenly, become hot, or become electrically energized. To avoid death or seri-
ous injury, observe the following precautions.
When working on the engine compartment
Make sure that the indicator on the power switch and the “READY” indicator
are both off.
Keep hands, clothing and tools away from the moving fan.
Be careful not to touch the engine, power control unit, radiator, exhaust mani-
fold, etc. right after driving as they may be hot. Oil and other fluids may also
be hot.
Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are
flammable.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the affected
area with clean water immediately. If you still experience discomfort, consult
a doctor.
When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature is
high. (P. 502)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
NOTICE
If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear
or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

Maintenance and care
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the hybrid system is cold.
Engine coolant reservoir
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to
the “FULL” line. (P. 628)
Power control unit coolant reservoir
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to
the “FULL” line. (P. 628)
Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35C [-31F])
For more details about coolant, contact any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.
If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine/power control unit coolant reservoir
caps, drain cock and water pump.
If you cannot find a leak, have any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for leaks
in the cooling system.

Check the radiator and condenser and clear away any foreign objects.
If either of the above parts is extremely dirty or you are not sure of their
condition, have your vehicle inspected by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
WA R N I N G
When the hybrid system is hot
Do not remove the engine/power control unit coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if the cap
is removed, causing serious injuries, such as burns.
NOTICE
When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion pro-
tection and cooling. Be sure to read the antifreeze or coolant label.
If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
Radiator and condenser
WA R N I N G
When the hybrid system is hot
Do not touch the radiator or condenser as they may be hot and cause serious
injuries, such as burns.
When the electric cooling fans are operating
Do not touch the engine compartment.
The electric cooling fans may keep rotating for about 3 minutes even after the
power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature is
high. Be sure the power switch is off when working near the electric cooling
fans or radiator grille.
