■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recommends
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 ser-
vices 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 anothe r duly qualified and equipped professional
will perform all of the scheduled maintenance on your vehicle reliably and economi-
cally 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 conditioning
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. 116)
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.
