(6)If your vehicle will be towing a trailer, load from your trailer will betransferred to your vehicle. Consul t this manual to determine how this
reduces the available cargo and luggage load capacity of your vehi-
cle.
Lexus does not recommend towing a trailer with your vehicle. Your vehicle is
not designed for trailer towing.
Example on your vehicle
Cargo capacity
Total load capacity
When 2 people with the combined weight of 366 lb. (166 kg) are riding
in your vehicle, which has a total lo ad capacity of 660 lb. (300 kg), the
available amount of cargo and luggage load capacity will be as follows:
660 lb. — 366 lb. = 294 lb. (300 kg —166 kg = 134 kg)
In this condition, if 2 more passengers with the combined weight of 258 lb.
(176 kg) get on, the available cargo and luggage load will be reduced as fol-
lows:
294 lb. — 258 lb. = 36 lb. (134 kg — 117 kg = 17 kg)
As shown in the above example, if the number of occupants increases,
the cargo and luggage load equaling the combined weight of the occu-
pants who got on later, by an amount. In other words, if an increase in the
number of occupants causes an excess of the total load capacity (com-
bined weight of occupants plus cargo and luggage load), you must
reduce the cargo and luggage on your vehicle.
