Lexus NX450h+ 2021 - Do-It-Yourself Maintenance

Do-it-yourself maintenance
What about do-it-yourself maintenance?
Many maintenance items are easy to do yourself if you have a little mechanical
ability and a few basic automotive tools.
Note, however, that some maintenance tasks require special tools and skills. These
are best performed by qualified technicians. Even if you’re an experienced do-it-
yourself mechanic, we recommend that repairs and maintenance be conducted by
any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
Any authorized Lexus retailer or repairer will keep a record of maintenance, which
could be useful should you ever require Warranty Service. Should you choose
to select a qualified and equipped professional other than an authorized Lexus
repairer to service or maintain your vehicle, we recommend that you request that a
record of maintenance be kept.
INFORMATION
■ 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 misfire (or misses), 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
If you notice any of these clues, take your vehicle to any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer as soon as possible. Your vehicle may
need adjustment or repair.
