NOTE
When the turn signal lever is operated for a lane change, the LAS & LDWS is
automatically disabled. The LAS & LDWS becomes operational again when the turn
signal lever is returned and the system detects white (yellow) lane lines while the vehicle
is being driven normally within its vehicle lane.
If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white (yellow) line, the system de termines that the driver is
making a lane change and the LAS & LDWS operation is temporarily canceled. The LAS
& LDWS becomes operational again when the system detects white (yellow) lane lines
while the vehicle is being driven normally within its vehicle lane.
If the vehicle deviates from its lane repeatedly within a short period of time, the LAS &
LDWS may not operate.

This section will guide you in the proper loading of your vehicle and/or trailer, to keep your
loaded vehicle weight within it s design rating capability, with or without a trailer. Properly
loading your vehicle will provide maximum retu rn of vehicle design performance. Before
loading your vehicle, familiarize yourself with the following terms for determining your
vehicle's weight ratings, with or without a trailer, from the vehicle's Safety Certification
Label and Tire and Load Information Label:
WA R N I N G
Overloaded Vehicle:
Overloading a vehicle is dangerous. The results of overloading can have serious consequences
in terms of passenger safety. Too much weight on a vehicle's suspension system can cause
spring or shock absorber failure, brake failu re, handling or steering problems, irregular tire
wear, tire failure or other damage.
Overloading makes a vehicle harder to drive an d control. It also increases the distance
required for stopping. In cases of serious overloading, brakes can fail completely, particularly
on steep grades. The load a tire will carry safely is a combination of the size of the tire, its load
range, and corresponding inflation pressure.
Never overload the vehicle and always observe th e vehicle's weight ratings from the vehicle's
Safety Certification and Tire and Load Information labels.
Base Curb Weight is the weight of the ve hicle including a full tank of fuel and all
standard equipment. It does not include passengers, carg o, or optional equipment.

Vehicle Curb Weight is the weight of your new vehicl e when you picked it up from your
dealer plus any aftermarket equipment.

Cargo Weight includes all weight added to the Base Curb Weight, including cargo and
optional equipment. When towing, trailer tongue load or king pin weight is also part of
cargo weight.

The cargo weight limit decreases depending on the number of vehicle occupants. The cargo
weight limit can be calculated by subtracting the total weight of the vehicle occupants from
the “combination weight of occupants and cargo should never exceed” value on the tire
label.

Examples: Based on a single occupant weight of 68 kg (150 lbs), and a value of 385 kg (849
lbs) for the
