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.

or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If wheel without the tire pressure warning valve and transmitter is used.
• If the ID code on the tire pressure warning valves and transmitters is not reg-
istered in the tire pressure warning computer.
Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-

Maintenance and care
WA R N I N G
Replacing light bulbs
Be sure to stop the hybrid system and turn off the lights. Do not attempt to
replace the bulb immediately after turning off the lights.
The bulbs become very hot and may cause burns.
Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth to
avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This may
damage the headlights or cause condensation to build up on the lens.
Do not attempt to repair or disassemble light bulbs, connectors, electric cir-
cuits or component parts.
Doing so may result in death or serious injury due to electric shock.
To prevent damage or fire
Make sure bulbs are fully seated and locked.
Check the wattage of the bulb before installing to prevent heat damage.
NOTICE
When replacing the outer foot lights
If the front window is stopping you from conducting the replace operation
properly, open the window on the side you are working on to allow you enough
space to work. Continuing the operation without giving yourself enough space
to work could lead you to scratch the vehicle.
