Example based on your vehicleCargo capacity
Total load capacity
When 2 people with the combined weight of 366 lb. (166 kg) are riding
in your vehicle, the available amount of cargo and luggage load capacity
will be as follows:
Vehicles without rear heig ht control air suspension
With third seats — total load capacity: 1315 lb. (595 kg)
1315 lb. - 366 lb. = 949 lb. (595 kg - 166 kg = 429 kg)
Without third seats
— total load capacity: 1525 lb. (690 kg)
1525 lb. - 366 lb. = 1159 lb. (690 kg - 166 kg = 524 kg)
Vehicles with rear height control air suspension
Total load capacity: 1280 lb. (580 kg)
1280 lb. - 366 lb. = 914 lb. (580 kg - 166 kg = 414 kg)
In this condition, if 3 more passengers with the combined weight of 388 lb.
(176 kg) get on, the available cargo and luggage load will be reduced as follows:

Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific gravity of
battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the rear 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 fro-
zen. 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 the 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 accumulated 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.

Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making a
turn.
● Note that when making a turn, the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. Compensate by making a
wider than normal turning radius.
● Slow down before making a turn, in crosswinds, on wet or slippery sur-
faces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in D.
Transmission shift range position must be in 5 in the S mode.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do not
make sudden downshifts while descending steep or long downhill
grades.
● Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause the brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may overheat
on hot days (at temperatures over 85°F [30°C]) when driving up a
long or steep grade. If the engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. ( →P. 744)

●After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred is
beyond the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing
vehicle-trailer increases as speed increases.
CAUTION
■Trailer towing precautions
●To tow a trailer safely, use extreme care and drive the vehicle in accordance with
the trailer’s characteristics and operating conditions. Failure to do so could cause
an accident resulting in death or serious injury. Vehicle stability and braking per-
formance are affected by trailer stability, brake setting and performance, and the
hitch. Your vehicle will handle differently when towing a trailer.
●Set the vehicle height to the LO mode and turn off the rear height control air sus-
pension when you connect a trailer, otherwise the vehicle height may change due
to the automatic leveling function, and you may catch part of your body in the
vehicle, resulting in an accident.
