Rear 200 kPa (2.0 kgf/cm2 or bar, 29 psi)
For sustained high speeds above 160 km/h (99 mph), in
countries where such speeds are permitted by law, add 40
kPa (0.4 kgf/cm
2 or bar, 6 psi) to the front tires and rear tires,
but never exceed the maximum cold tire pressure molded
on the tire sidewall.

FUEL GAUGE
Low fuel level warning light
The gauge is displayed when the ignition switch is on and
indicates the approximate quantity of fuel remaining in the
tank.
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
 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.

DRIVING TIPS
252
Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a longer
stopping distance, and it may pull to one side when
the brakes are applied. Also, the parking brake will
not hold the vehicle securely.WINTER DRIVING TIPS
Make sure you have a proper freeze protection of engine
coolant.
Your coolant must contain ethylene −glycol type coolant for a
proper corrosion protection of aluminum components. Use
“Toyota Genuine Long Life Coolant” or equivalent. See
“Checking the engine coolant level” on page 315 for
instructions.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
When it is extremely cold, we recommend to use 60% solution
for your Lexus, to provide protection down to about −50C
(−58 F). Do not use more than 70% solution for better coolant
performance.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it
must be in top shape to pr ovide enough power for winter
starting. Page 341 tells you how to visually inspect the battery.
Your Lexus dealer and most service stations will be pleased to
check the battery charge level.

ENGINE
316If the coolant level drops within a short time after replenishing,
there
may be a leak in the system. V isually check the radiator,
hoses, engine coolant filler cap, radiator cap and drain cock
and water pump.
If you can find no leak, have your Lexus dealer test the cap
pressure and check for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not remove the radiator
cap when the engine is hot.
Coolant type selection
Use of improper coolants may damage your engine cooling
system. Your coolant must contain ethylene −glycol type
coolant for a proper corrosion protection of your engine that
contains aluminum components. We have used “Toyota
Genuine Long Life Coolant” in your Lexus vehicle. In order to
avoid technical problems, we strongly recommend using
“Toyota Genuine Long Life Coolant” or equivalent.
In addition to preventing freezing and subsequent damage to
the engine, this type of coolant will also prevent corrosion.
Further supplemental inhibitors or additives are neither
needed nor recommended.
Read the coolant container for information on freeze
protection. Follow the manufacturer’s directions for how much
to mix with plain water (preferably demineralized water or
distilled water). The total capacity of the cooling system is
given on page 307. We recommend to use 50% solution for your Lexus, to provide
protection
down to about −35C (− 31F). When it is extremely
cold, to provide protection down to about −50C (−58F), 60%
solution is recommended. Do not use more than 70% solution
for better coolant performance.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
The engine cooling system is integral to maximizing
performance of your Lexus vehicle. In line with this, it is
strongly recommended that you use “Toyota Genuine Long
Life Coolant” for protecting the system, as it is an
ethylene− glycol based premium antifreeze coolant with
excellent corrosion protection properties that has been
specifically formulated for use in Lexus vehicles.
Please contact your Lexus dealer for further details of the
“Toyota Genuine Long Life Coolant” range.
