What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself if you have a little mechanical
ability and a few basic automotive tools. Simple instructions for how to perform them
are presented in this section.
Note, however, that some maintenance tasks require special tools and skills. These
are best performed by qualified technicians. Even if you are an experienced do-it-
yourself mechanic, we recommend that repairs and maintenance be conducted by
your Lexus dealer who will keep a record of maintenance on your vehicle. This record
could be helpful should you ever require Warranty Service.
■ 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 conditioning sys-
tem 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. 101)
● Engine continually runs hot, oil pressure gauge stays low
If you notice any of these clues, take your vehicle to your Lexus dealer as soon as possi-
ble. Your vehicle may need adjustment or repair.
