gage load capacity calculated in Step
4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
( P.123)
Lexus does not recommend towing a
trailer with your vehicle. Your vehicle is not
designed for trailer towing.
Cargo capacity
Total load capacity (vehicle capac-
ity weight) ( P.326)
When 2 people with the combined
weight of A lb. (kg) are riding in your
vehicle, which has a total load capacity
(vehicle capacity weight) of B lb. (kg),
the available amount of cargo and lug-
gage load capacity will be C lb. (kg) as
follows:
B
*2 lb. (kg) - A*1 lb. (kg) = C*3 lb. (kg)
*1: A =Weight of people
*2: B =Total load capacity
*3:C =Available carg o and luggage load
In this condition, if 2 more passengers with
the combined weight of D lb. (kg) get on,
the available cargo and luggage load will
be reduced E lb. (kg) as follows:
C lb. (kg) - D*4 lb. (kg) = E*5 lb. (kg)
*4: D =Additional weight of people
*5: E =Available cargo and luggage load
As shown in the example above, if the
number of occupant s increases, the
cargo and luggage load will be
reduced by an amount that equals the
increased weight due to the additional
occupants. In other words, if an
increase in the number of occupants
causes an excess of the total load
capacity (combined weight of occu-
pants plus cargo and luggage load),
you must reduce the cargo and lug-
gage on your vehicle.

WARNING
■Stopping the engine in an emergency
If you want to stop the engine in an emer-

2 seconds, or press it briefly 3 times or
more in succession. ( P.284)
However, do not touch the engine switch

will be lost. This will make it more difficult
to steer and brake, so you should pull
over and stop the vehicle as soon as it is
safe to do so.
■When parking
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
to enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the engine.
●Do not leave the vehicle with the
engine running for a long time. If such
a situation cannot be avoided, park the
vehicle in an open space and ensure
that exhaust fumes do not enter the
vehicle interior.
●Do not leave the engine running in an
area with snow build-up, or where it is
snowing. If snowbanks build up around
the vehicle while the engine is running,
exhaust gases may collect and enter
the vehicle.
