GS350/250_EE (OM30C36E)
Where to go for service?
In order to maintain your vehicle in the best possible condition, Lexus rec-
ommends that all repairs and service operations 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 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 condi-
tioning 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
immediately.)
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. 9 9 )
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
GS350/250_EE (OM30C36E)
CAUTION
Discharge headlights
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional before replacing the discharge headlights
(including light bulbs).
Do not touch the discharge headlight’s high voltage socket when the head-
lights are turned on.
An extremely high voltage of 30000 V will be discharged and could result
in death or serious injury by electric shock.
Do not attempt to take apart or repair the headlight bulbs, connectors,
power supply circuits, or related components.
Doing so could result in electric shock and death or serious injury.
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.
