CAUTION
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compart-
ment:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failing to do so may result in death or serious injury.
●Stow cargo and luggage in the luggage compartment whenever possi-
ble.
●Do not stack anything in the luggage compartment higher than the
seatbacks. Such items may be thro
wn about and possibly injure peo-
ple in the vehicle in the event of sudden braking or in an accident.
●Do not place cargo or luggage in or on the following locations as the
item may get under the brake or accelerator pedal and prevent the
pedals from being depressed properly, block the driver’s vision, or hit
the driver or passengers, causing an accident.

CAUTION
■Storage precautions
●Secure all items in the occupant compartment, as they may shift and
injure someone during sudden braking, sudden swerving or an acci-
dent.
●When you fold down the rear seats, long items should not be place
directly behind the front seats.
●Never allow anyone to ride in the luggage compartment. It is not
designed for passengers. They should ride in their seats with their seat
belts properly fastened. Otherwise, th ey are much more likely to suffer
death or serious bodily injury, in t he event of sudden braking, sudden
swerving or an accident.
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehicle
weight rating.
●Even if the total load of occupant’s weight and the cargo load is less
than the total load capacity, do not apply the load unevenly.
Improper loading may cause deterioration of steering or braking con-
trol which may cause death or serious injury.
■Cross rail adjustment
Make sure the cross rails are locked securely by pushing forward and
rearward them.
Failure to do so may cause an unexpected accident.

CAUTION
■When loading cargo
Observe the following precautions:
●Place the cargo so that its weight is distributed evenly between the
front and rear axles.
●If loading long or wide cargo, never exceed the vehicle overall length
or width. (
P. 800)
●Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
●Loading cargo on the roof luggage carrier will make the center of grav-
ity of the vehicle higher. Avoid high speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failure to operate this vehicle correctly
and result in death or serious injury.
●If driving for a long distance, on rough roads, or at high speeds, stop
the vehicle now and then during the trip to make sure the cargo
remains in its place.
●Do not exceed 150 lb. (68 kg) cargo weight on the roof luggage carrier.
NOTICE
■When loading cargo (vehicles with moon roof)
Be careful not to scratch th e surface of the moon roof.

Vehicle load limits
■Total load capacity and seating capacity
These details are also described on the tire and loading information
label. (P. 699)
CAUTION
■Overloading the vehicle
Observe the total load capacity when you load the vehicle. ( P. 800)
Otherwise, it may not only cause damage to the tires, but also degrade
steering and braking ability, resulting in an accident.
Vehicle load limits include total load capacity, seating capacity,
TWR (Trailer Weight Rating) and cargo capacity.
■Total load capacity (vehicle capacity weight): ( P. 800)
Total load capacity means the combined weight of occupants, cargo
and luggage.
■ Seating capacity: 7 or 8 occupants (Front 2, Rear 5 or 6)
Seating capacity means the maxi mum number of occupants whose
estimated average weight is 150 lb. (68 kg) per person.
■ TWR (Trailer Weight Rating): ( P. 376, 801)
TWR means the maximum gross tra iler weight (trailer weight plus
its cargo weight) that your vehicle is able to tow.
■ Cargo capacity
Cargo capacity may increase or decrease depending on the weight
and the number of occupants.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
● To ensure proper operation of th e climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
● Remove any ice that has accumu lated on the vehicle chassis.
● Periodically check for and remove any excess ice or snow
that may have accumulated in the wheel well or on the
brakes.

Accelerate the vehicle slowly and drive at a reduced speed suit-
able to road conditions.
