2012 TOYOTA CAMRY check engine

140 2-1. Driving procedures
CAUTION
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P or N, the vehicle may accelerate
suddenly and unexpectedly, causing an accident.
● Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the engine is running, and apply the
parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

142 2-1. Driving procedures
CAUTION
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Inhaling exhaust gases may lead to death or a serious health
hazard.
●If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
● The exhaust system should be checked occasionally. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise,
be sure to have the vehicle inspected and repaired by your Toyota dealer.
Failure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.
■ When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever
or depress the accelerator pedal, this could cause an accident or fire due to
engine overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.

● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
● Brake function
