THEFT PREVENTION LABELS
17L002
Your new vehicle carries theft prevention labels which are
approximately 56 mm (2.20 in.) by 16 mm (0.63 in.).
The purpose of these labels is to reduce the incidence of
vehicle thefts by facilitating the tracing and recovery of parts
from stolen vehicles. The label is designed so that once it is
applied to a surface, any attempt to remove it will result in
destroying the integrity of the label. Transferring these labels
intact from one part to another will be impossible.
NOTICE
You should not attempt to remove the theft prevention labels as it may violate certain state or federal laws.

cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see ºIf your vehicle will not startº\
.
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work, so steering and
braking will be much harder than usual.
IF YOUR VEHICLE WILL NOT START
(a) Simple checks
Before making these checks, make sure you have followed the
correct starting procedure instructions in ºHow to start the
engineº on page 168 and that you have sufficient fuel. Since
your vehicle is equipped with the engine immobiliser system,
also check whether the other keys will start the engine. If they
work, your key may be broken. Have the key checked at your
Lexus dealer. If none of your keys work, the system is possibly
broken. Call your Lexus dealer. See ºKeysº on page 8.
If the engine is not turning over or is turning over too
slowly ±
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked,
the battery is discharged. You may try jump starting. See º(c)
Jump startingº for further instruction.
If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See
ºForewordº.)
