When driving
CAUTION
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle in hot areas.
• Gas may leak from a cigarette lighter or spr
ay can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic
m
aterial of glasses to deform or crack.
• Soft drink cans may fracture, causing the co ntents
to spray over the interior of
the vehicle, and may also cause a short circuit in the vehicle’s electrical com -
ponents.
●Always set the parking brake, shift the se lector lever to P, stop the engine and
lock the vehicle. 
Do not leave the vehicle unattend ed
while the engine is running.
●Do not leave the engine running in an area with snow build up, or where snow is
expected to fall. 
Exhaust gases may enter the interior of the vehicle and cause gas poisoning.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the selector
le

ver or press the accelerator pedal, which could cause an accident or fire due to
abnormal engine overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust fumes may enter the vehicle and cause gas poisoning.

■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indi -
cates the maximum range of engine revolutions.
●The engine may be overheating if the temperature gauge is in the red zone (H).
Immediately stop the vehicle in a safe place and check the engine. ( P.359 )

2-5. Driving information

When driving
• As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
• Avoid sudden braking as you may sk id, r
esulting in jackknifing and loss
of control. This is especially true on wet or slippery surfaces.
• Avoid jerky starts or sudden acceleration.
• Avoid jerky steering and sharp turn s, and slo
w down before making a
turn.
• Note that when making a turn, the tr ailer wheels will be closer than the
v
ehicle wheels to the inside of th e turn. Compensate by making a
larger than normal turning radius.
• Crosswinds and rough roads will ad v
ersely affect handling of your
vehicle and trailer, causing sway. Peri odically check the rear to prepare
for being passed by large trucks or buses, which may cause your vehi-
cle and trailer to sway. If s
waying occurs, firmly grip the steering wheel,
reduce speed immediately but gradually, and steer straight ahead.
Never increase speed. If you make no extreme correction with the
steering or brakes, your vehi cle and trailer will stabilize.
• Take care when passing other vehicl es. P
assing 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.
• In order to maintain efficient engine br
aking and electrical charging
performance, do not use overdrive. Transmission shift range position
must be in “4”, in the “S” mode.
• Due to the added load of the traile r
, 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. See “If your vehicle
overheats” ( P.359 ).

CAUTION
■Burns/ excessive cooling
●The following passengers should take extra care to avoid burns:
• Babies, small children, elderly persons, si
ck or physically disabled persons.
• Persons who have sensitive skin.
• Exhausted persons.
• Persons who have taken alcohol or drug s whi
ch induce sleep (sleeping drugs,
cold remedies, etc.)
●Do not use a blanket or cushion on the seat. Using the climate control seat with
a blanket or cushion increases the temperature of the seat and may lead to over -
heating.
●Take care not to overuse the cooling function, as it may cool the above men -
tioned passengers excessively minor burns and overheating/ excessive cooling
NOTICE
■To prevent seat heater damage
Do not put unevenly weighted objects on the
seat and do not stick sharp objects
(needles, nails, etc.) into the seat.

5-2. Steps to take in an emergency
■Overheating
If you observe the following, your vehicle may be overheating.
• The engine coolant temperatur
e gauge enters the red zone or a loss of power is
experienced.
• Steam is coming out from under the hood.
CAUTION
■To prevent an accident or injury when in specting under the hood of your vehicle
●Keep hands and clothing away from the fan and other belts while the engine is
running.
●Do not loosen the radiator cap while the engine and radiator are hot. 
Serious injury could result from scalding hot fluid and steam blown out under
pr
essure.
NOTICE
■When adding engine coolant
Wait until the engine has cooled do wn befor
e adding engine coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot engine too quickly
ca
n cause damage to the engine.
Add engine coolant if required.
Water can be used as an emer -
gency measure if engine coolant is
una
vailable.( P.367 )
