NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indi-
cates the maximum engine speed.
●The engine may be overheating if the engine coolant temperature gauge is in the
red zone (H). In this case, immediately stop the vehicle in a safe place, and check
the engine after it has cooled completely. (

2-5. Driving information
RX350/270_EE■Important points regarding turning
The wheels of the trailer will travel closer to the inside of the curve than
the wheels of the vehicle. To make allowance for this, take the turns
wider than you would normally do.
■Important points regarding stability
Vehicle movement resulting from uneven road surfaces and strong
crosswinds will affect handling. The vehicle may also be rocked by
passing buses or large trucks. Frequently check behind when moving
alongside such vehicles. As soon as such vehicle movement occurs,
immediately start to decelerate smoothly by slowly applying the
brakes. Always steer the vehicle straight ahead while braking.
■Passing other vehicles
Consider the total combined length of your vehicle and trailer and
ensure that the vehicle-to-vehicle distance is sufficient before execut-
ing lane changes.
■Transmission information
Refrain from driving in 6 range in S mode to maintain the effectiveness
of the engine brake and the charge performance of electrical compo-
nents.
■If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures
exceeding 30°C (85°F) may result in the engine overheating. If the
engine coolant temperature gauge indicates that the engine is over-
heating, turn the air conditioning off immediately, leave the road and
stop the vehicle in a safe place. (→P. 5 9 8 )
■When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle and
trailer. Firmly set the parking brake and shift the shift lever to P.

Maintenance and care
RX350/270_EE
■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recommends
that maintenance service operations as well as other inspections and repairs be
carried out by authorized Lexus dealers or repairers or other duly qualified and
equipped professionals. For repairs and services covered by your warranty, 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 utiliz-
ing 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 professional
will perform all of the scheduled maintenance on your vehicle reliably and econom-
ically 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 indi-
cate 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 driving straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches
the floors, vehicle pulls to one side when braking
●Engine coolant temperature continually higher than normal
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 possible.
Your vehicle may need adjustment or repair.

Maintenance and care
RX350/270_EE
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precaution:
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fans and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driv-
ing 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 or the battery. Fuel
and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
●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 “ENGINE START STOP” switch is off.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fans may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. (→P. 4 7 8 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in your eyes

Engine coolant
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line. (→P. 5 9 8 )
■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% deionized
water. (Minimum temperature: -35°C [-31°F])
For more details about coolant, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.

5-2. Steps to take in an emergency
When trouble arises
RX350/270_EEAdd coolant if necessary.
(→P. 4 7 0 )
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fans operate and to check for coolant
leaks from the radiator or hoses.
The fans operate when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating by checking
the fan sound and air flow. If it is difficult to check these, turn the air con-
ditioning system on and off repeatedly.
(The fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the engine immediately and contact any authorized
Lexus dealer or repairer, or another duly qualified and
equipped professional.
If the fans are operating:
Have the vehicle inspected at the nearest authorized Lexus
dealer or repairer, or another duly qualified and equipped pro-
fessional.
