Engine coolant temperature gauge
„„4.2-inch„„10.25-inch
ONX4040007OTM040010This gauge indicates the temperature
of the engine coolant when the ignition
switch is in the ON position.
NOTICE
If the gauge pointer moves beyond the
normal range area toward the H (or
HOT) position, it indicates overheating
that may damage the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “If the Engine
Overheats” section in chapter 8.
WARNING
Never remove the engine coolant
reservoir cap when the engine is hot.
The engine coolant is under pressure
and could cause a severe burn or injury.
Wait until the engine is cool before
adding coolant to the reservoir.
Fuel gauge
„„4.2-inch„„10.25-inch
ONX4040008 OTM040012This gauge indicates the approximate
amount of fuel remaining in the fuel tank.
Information
• The fuel tank capacity is given in
chapter 2.
• The fuel gauge is supplemented by
a low fuel warning light, which will
illuminate when the fuel tank is nearly
empty.
• On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in
the tank.
WARNING
Running out of fuel can expose vehicle
occupants to danger.
You must stop and obtain additional
fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the “E
(Empty) or 0” level.
NOTICE
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire damaging
the catalytic converter.

Engine overheated / Engine has
overheated
This message is displayed when the
engine coolant temperature is above
248°F (120°C). This means that the
engine is overheated and may be
damaged.
If your vehicle is overheated, refer to
“Overheating” section in chapter 8.
Check headlight
This warning message is displayed if the
headlamps are not operating properly.
In addition, if a specific lamp(turn signal
lamp etc.) is not operating properly, the
warning message according to a specific
lamp (turn signal lamp etc.) is displayed.
A corresponding bulb may need to be
replaced.
Make sure to replace the burned out
bulb with a new one of the same wattage
rating.

Automatic reverse
ONX4E050030
During power opening and closing if the
power liftgate is blocked by an object or
part of the body, the power liftgate will
detect the resistance.
• If the resistance is detected while
opening the liftgate, it will stop and
move in the opposite direction.
• If the resistance is detected while
closing the liftgate, it will stop and
move in the opposite direction.
However, if the resistance is weak such
as from an object that is thin or soft, or
the liftgate is near the latched position,
the automatic stop and reversal may not
detect the resistance. If the automatic
reversal feature operates continuously
more than twice during opening or
closing operation, the power liftgate may
stop at that position. At this time, close
the liftgate manually and operate the
liftgate automatically again.
WARNING
Never intentionally place any object
or part of your body in the path of
the power liftgate to make sure the
automatic reverse function operates.
NOTICE
Do not put heavy objects on the power
liftgate before you operate the power
liftgate. Additional weight may damage
the operation of the system.
Non-operating conditions of the
power liftgate
• The power liftgate does not open
when the vehicle is in motion.
The chime will sound if you drive
over 2mph (3km/h) with the
liftgate opened. Stop your vehicle
immediately at a safe place and check
if your liftgate is opened.
• Operating the power liftgate more
than 5 times continuously could
cause damage to the operating motor.
If this occurs, the power liftgate
system enters into thermal protection
mode to prevent the motor from
overheating. In thermal protection
mode, the power liftgate will not
operate. If any of the power liftgate
buttons are pressed to try to open the
liftgate, the chime will sound 3 times
but the liftgate will not operate.
Allow the power liftgate system
to cool for about 1 minute before
operating the system again.
• The power liftgate can be operated
when the engine is not running.
However the power liftgate operation
consumes large amounts of vehicle
electric power. To prevent the battery
from being discharged, do not
operate it excessively e.g.: more than
approximately 10 times repeatedly.
• To prevent the battery from being
discharged, do not leave the power
liftgate in the open position for a long
lime.
• When jacking up the vehicle to
change a tire or repair the vehicle, do
not operate the power liftgate. This
could cause the power liftgate to
operate improperly.
• In cold and wet climates, the power
liftgate may not work properly due to
freezing conditions.

the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.
• Use the air conditioning system every
month for a few minutes to ensure
maximum system performance.
• If you operate the air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause
the outer surface of the windshield to
fog up, causing loss of visibility. In this
case, set the mode selection knob to
the
position and set the fan speed control knob to the lowest speed
setting.
