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.

(d) Emergency towing
G40019
If towing is necessary, we recommend you to have it done
by your Lexus dealer or a commercial tow truck service.
If towing service is not available in an emergency, your
vehicle may be temporarily towed by a cable or chain
secured to the emergency towing eyelet. Use extreme
caution when towing the vehicle.
To install the front towing eyelet, see “Installing towing eyelet”
on page 488.
NOTICE
 Only use specified towing eyelet; otherwise your
vehicle may be damaged.
 Never tow a vehicle from the rear with four wheels on
the ground. This may cause serious damage to the
transmission.
A driver must be in the vehicle to steer it and operate the
brakes.
Towing in this manner may be done only on hard −surfaced
roads for a short distance and at low speeds. Also, the wheels,
axles, drive train, steering and brakes must all be in good
condition.
CAUTION
Use extreme caution when towing the vehicle. Avoid
sudden starts or erratic driving maneuvers which would
place excessive stress on the emergency towing eyelet
and towing cable or chain. The eyelet and towing cable
or chain may break and cause serious injury or damage.
NOTICE
Use only a cable or chain specifically intended for use
in towing vehicles. Securely fasten the cable or chain
to the towing eyelet provided.

come off when being towed and result in death or
serious injury.

4. Pull the dipstick out and look at the oil level while holding a
rag under the end. If it is between the full level mark (
5 ) and
the low level mark ( 4 ), it is O.K.

If the oil level is below or only slightly above the low level
mark, add engine oil of the same type as already in the
engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. We recommend that you use a funnel
when adding oil. The approximate quantity of oil needed to
raise the level between low and full on the dipstick is indicated
as follows:
1.5 L (1.6 qt., 1.3 lmp. qt.)
For the engine oil capacity, see “Specifications” on pages 512
and 515.
When the level reaches within the correct range, return the
filler cap and turn the cap clockwise until you hear a click.
