Place the ignition key in the ºACCº position.
NOTICE

Do not tow with the key removed or in the ºLOCKº
position, as the steering lock mechanism is not strong
enough to hold the front wheels straight.

When lifting wheels, take care to ensure adequate
ground clearance for towing at the opposite end of the
raised vehicle. Otherwise, the bumper and/or
underbody of the towed vehicle will be damaged
during towing.

3. Insert your finger, the screwdriver or equivalent into the
hole to push down the shift lock override button. You can shift
out of ºPº position only while pushing the button.
4. Shift into ºNº position.
5. Insert the cover.
6. Start the engine. 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 ORLOCK YOURSELF OUT
Many Lexus dealers can make a new key if you can give
them the key number. Since your vehicle is equipped with
the engine immobiliser system, the dealer will also need
your master key.
See the suggestion given in ºKeysº on page 12.
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.
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 system must be replaced.

ENGINE COMPARTMENT OVERVIEW(SC400)

ENGINE
345
If the oil level is below or only slightly above the low line
(low
level mark), add engine oil of the same type as alr eady
in the engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. The approximate quantity of oil
needed to fill between the low line (low level mark) and the
full line (full level mark) on the dipstick is indicated below for
reference. When the level reaches within the correct range, return the
filler cap and turn the cap clockwise until you hear a click.
Oil quantity. L (qt., lmp. qt.) SC400, SC300 ± 1.5 (1.6,
1.3)
NOTICE
Avoid
overfilling, or the engine could be damaged. Check
the oil level on the dipstick once again after adding the oil.

CHASSIS
362If the vehicle has been driven around 80 km/h (50 mph) for
20 minutes (a little more in frigid temperatures), the fluid is
hot (60C ± 80C or 140F ± 175F). You may also check
the level when the fluid is cold (about room temperature,
10 C ± 30C or 50F ± 85 F) if the engine has not been run
for about five hours.
1. Clean all dirt off the reservoir.
2. Remove the filler cap by turning it counterclockwise and
wipe the dipstick clean.
3. Reinstall the filler cap.
4. Remove the filler cap again and look at the fluid level. If
the fluid is cold, the level should be in the ºCOLDº range on
the dipstick. Similarly, if it is hot, the fluid level should be in
the ºHOTº range. If the level is at the low side of either range,
add automatic transmission fluid DEXRON
II or III to bring
the level within the range. 5. After replacing the filler cap, visually check the steering
box case, vane pump and hose connections for leaks or
damage.

CHASSIS
371
CAUTION
Do not exceed 50 km/h (30 mph) or the chain
manufacturer's recommended speed limit, whichever is
lower.
 Drive carefully avoiding bumps, holes, and sharp turns,
which may cause the vehicle to bounce.
 Avoid sharp turns or locked±wheel braking, as use of
chains may adversely affect vehicle handling.
