Warning
An underhood electric fan can
start up even when the engine is
not running and can cause injury.
Keep hands, clothing, and tools
away from any underhood
electric fan.
Warning
Do not touch heater or radiator
hoses, or other engine parts.
They can be very hot and can
burn you. Do not run the engine if
there is a leak; all coolant could
leak out. That could cause an
engine fire and can burn you. Fix
any leak before driving the
vehicle.
If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be at the
top rib on the middle of the tank. If it
is not, the vehicle may have a leak
at the radiator hoses, heater hoses,
radiator, water pump, or somewhere
else in the cooling system.
If there seems to be no leak, with
the engine on, check to see if the
electric engine cooling fan is
running. If the engine is
overheating, the fan should be
running. If it is not, the vehicle
needs service. Turn off the engine.
Align the air cleaner/filter with
the indicated point on the base
of the air cleaner/filter housing
and install the air cleaner/filter.
The outer air cleaner/filter seal
must be fitted properly in the
air cleaner/filter housing...
The engine cooling system in the
vehicle is filled with DEX-COOL
engine coolant mixture. This coolant
needs to be checked and changed
at appropriate levels...
Other information:
This vehicle is equipped with
airbags. See Airbag System.
Airbags are designed to inflate if the
impact exceeds the specific airbag
system's deployment threshold.
Deployment thresholds are used to
predict how severe a crash is likely
to be in time for the airbags to
inflate and help restrain the
occupants...
If the interior temperature is
extremely high, the instrument
cluster may indicate that ACC is
temporarily unavailable. This can be
caused by extreme hot weather
conditions with direct sunlight on the
front camera. ACC will return to
normal operation once the cabin
temperature is lower...
