2005 Lexus IS300 brake

IN CASE OF AN EMERGENCY
305
SV04013
2Insert your finger, the screwdriver or equivalent into the
hole to push down the shift lock override button. You can
shift the selector lever while pushing the button.
For your safety, keep the brake pedal depressed.
Be sure to have the system checked by your Lexus dealer as
soon as possible.
IF YOU LOSE YOUR KEYS OR LOCK YOURSELF OUT
You can purchase a new key at your Lexus dealer if you
can give them the key number and master key.
Even if you lose only one key, contact your Lexus dealer to
make a new key. If you lose all your master keys, you cannot
make new keys; the whole engine immobilizer system must be
replaced.
See the suggestion given in ªKeysº on page 8.
You can use the wireless remote control system with the new
key. Contact your Lexus dealer for detailed information.
If your keys are locked in the vehicle and you cannot get a
duplicate, many Lexus dealers can still open the door for you,
using their special tools. If you must break a window to get in,
we suggest breaking the smallest side window because it is the
least expensive to replace. Be extremely cautious to avoid cuts
from the glass.

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 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 driving straight on a level
road

Strange noises related to suspension movement

Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, 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 your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.

could result in serious vehicle damage and possibly
personal injury.
