CAUTION
■When the gross vehicle mass limit or maximum permissible axle capacity is
exceeded
Do not exceed the established speed limit for towing a trailer in built-up areas or
100 km/h (62 mph), whichever is the lower.

■Before descending hills or long declines
Reduce speed and downshift. However, never downshift suddenly while descend-
ing steep or long downhill grades.
■Operation of the brake pedal
Do not hold the brake pedal depressed often or for long periods of time.
Doing so may result in the brake overheating or reduce braking effects.

●For vehicles with electronically modulated air suspension, set the vehicle height
to LO mode and turn off the electronically modulated air suspension to prevent
the vehicle height from automatically changing.

Cleaning and protecting the vehicle exterior
■Automatic car washes
●Before washing the vehicle:
•Fold the mirrors.
• Turn off the power back door system (if equipped).
●Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
●In certain automatic car washes, the rear spoiler may interfere with machine
operation. This may prevent the vehicle from being cleaned properly or result in
damage to the rear spoiler.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the
windows and the air suspension unit (if equipped).
●Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
Perform the following to protect the vehicle and maintain it in prime condi-
tion:
●Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
●For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.

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.

serious injury:
●When using a floor jack, follow the instructions of the manual provided with the
jack.
●Do not use the jack that was supplied with your vehicle.
●Do not put any part of your body underneath the vehicle when it is supported
only by the floor jack.

floor jack.
●Vehicles with electronically modulated air suspension:
Be sure to turn off the height control and stop the engine. Otherwise, the vehicle
height may change due to the automatic leveling function. (→P. 2 5 6 )
●Lift up the vehicle using a floor jack such as
the one shown in the illustration.
