4Maintenance and care5When trouble arises

158 2-1. Driving procedures
FT86_EE
CAUTION
Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 178, 184)
Do not adjust the position of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents,
resulting in death or serious injury.
Always check that all passengers' arms, heads or other parts of their body
are not outside the vehicle, as this may result in death or serious injury.
When driving on slippery road surfaces
Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
Sudden acceleration, engine braking due to shift changing, or changes in
engine speed could cause the vehicle to skid, resulting in an accident.
After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
When shifting the shift lever
On vehicles with an automatic transmission, be careful not to shift the shift
lever with the accelerator pedal depressed. Shifting the shift lever to a
gear other than P or N may lead to unexpected rapid acceleration of the
vehicle that may cause an accident and result in death or serious injury.
Do not place items in the shift lever's surrounding area. It may cause incor-
rect operation.
If the shift boot is pulled out during cleaning, return it to its previous posi-
tion. If the shift boot is left pulled out, the shift lever may become difficult to
operate.

CAUTION
If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional as soon as
possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.
When the vehicle is stopped
Do not race the engine.
If the vehicle is in any gear other than P (vehicles with an automatic trans-
mission only) 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.
On vehicles with an automatic transmission, 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.

When driving
FT86_EE
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 any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional. 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, you may 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
ventilated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.

NOTICE
Avoiding damage to vehicle parts
Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
On vehicles with an automatic transmission, do not race the engine for
more than 5 seconds in any position except the N or P position when the
brake is applied or when chocks are used in the wheels. This may cause
the transmission fluid to overheat.
If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehicle.
It may be difficult to control your vehicle.
The vehicle will make abnormal sounds or vibrations.
The vehicle will lean abnormally.
Information on what to do in case of a flat tire (P. 371, 379)
When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
Engine stalling
Short in electrical components
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 any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional check the following:
Brake function
Changes in quantity and quality of oil and fluid used for the engine, trans-
mission, differential, etc.
Lubricant condition for the propeller shaft, bearings and suspension joints
(where possible) and the function of all joints, bearings, etc.
