Starting and Stopping the
Vehicle (Gasoline Only)
Check around the Vehicle before
Starting the Engine
Proper care and operation will not
only extend the service life of your
vehicle but also improve fuel
economy.
Before pulling away, perform a
thorough safety check, making sure
there are no children or obstructions
around the vehicle. Take off the
chocks after confirming that the
parking brake is securely applied.Sit behind the wheel, adjust the seat
position, and buckle up the seat
belt. The passengers are also
required to buckle up the seat belts.
Adjust the positions of the steering
wheel and mirrors. Lock the doors.
Turn the power of the dome light or
accessories OFF before starting the
engine. See
Seat Position 044,
Seat Belts 049, Steering Wheel
Adjustment 072, and Mirrors039.
Keep the Floor Around the
Driver's Seat Clean and Tidy{Warning
It is extremely dangerous to have
empty cans, empty bottles or
other items rolling around on the
floor because they could get
trapped under the brake pedal
and prevent brake application.
For proper pedal operation, it is
also essential to lay floor mats
properly. Incorrectly installed floor
mats would hinder free movement
of the pedals. (Continued)
Warning (Continued)
Do not use the dashboard pocket
or the top of the dashboard as a
place to put items that could roll,
which could interfere with your
driving. You and others could be
seriously injured.
Choose Your Footwear Suitable
for Driving
{Warning
Choose footwear that ensures
proper operation of pedals when
driving the vehicle. Use of
footwear unsuitable for driving
may cause an accident.
Checks Before Operating
Allow the engine to warm up before
driving. While the engine is warming
up, the following checks should
be made: 1. Observe the engine oil pressure warning light. The
light should go out when the

10716700) - 2017 - crc - 12/6/16
Driving and Operating 167
feature. To restart when you're
already moving, use
N (Neutral) only.
Do not try to shift to P (Park) if
your vehicle is moving. If you
do, you could damage the
transmission. Shift to P (Park)
only when your vehicle is
stopped.
2. Do not push the accelerator pedal before starting your
engine. In some other vehicles
you might need to do this, but
because of your vehicle's
computer systems, you do not
need to.
3. Turn your ignition key to Start. When the engine starts, let go
of the key. The idle speed will
go down as your engine
gets warm.
4. If it does not start right away, hold your key in START. If it
doesn't start in 3 seconds,
push the accelerator pedal
about one-quarter of the way
down for 12 more seconds,
or until it starts. 5. If your engine still will not start
(or starts but then stops), it
could be flooded with too much
gasoline. Try this: Wait 20 to
30 seconds to let the starter
motor cool down. Then push
your accelerator pedal all the
way to the floor. Hold it there.
Then, hold the key in START
for no more than 10 seconds.
This clears the extra gasoline
from the engine.
If the engine still does not start, wait
another 20 to 30 seconds and do
Step 5 again.
Hot Engine Restart
If your engine is already hot and
then stalls, turn your ignition key to
ACC. Then, turn your key to ON,
and wait about 20 to 30 seconds
before you restart your engine.
When the engine starts, let go of the
key and the accelerator pedal.
Your engine is designed to work
with the electronics in your vehicle.
If you add electrical parts or
accessories, you could change the
way the fuel injection system operates. Before adding electrical
equipment, check with your dealer.
If you do not, your engine might not
perform properly.
If you ever have to have your
vehicle towed, see the part of this
manual that tells how to do it without
damaging your vehicle. See
Towing
the Vehicle 0332.
Recommendations for Warming
Up the Engine
The engine is sufficiently warmed
up when the needle of the engine
coolant temperature gauge starts
to move.
. Do not race the engine or
quickly accelerate before the
engine has sufficiently warmed
up. Oil would not have
adequately reached and
lubricated components, and a
breakdown may result.
. The exhaust pipe becomes
extremely hot while the engine is
idling. Before warming up the
engine, make sure there is no

2. Move the selector lever in theP position, check that the shift
indicator is indicating P, and
slowly ease your right foot off
the brake pedal.
3. Stop the engine and remove the key. When the selector
lever is not placed in the P
position, the shift lock system
operates and the key cannot
be removed.
See Starting and Stopping the
Vehicle (Gasoline Only) 0165 or
Starting and Stopping the Vehicle
(Diesel Only) 0168, and Parking
Brake 0221.
If you cannot move the selector
lever from the P position after
starting the engine, perform the
following necessary checks:
. Check that you are firmly
pressing the brake pedal.
. Check if the area where your
vehicle is parked is not a slope.
. If your vehicle is parked on a
downhill slope, the push
operation of the selector lever
may become heavy to move. In this case, you can operate the
selector lever more smoothly by
pushing the selector lever
towards the front of the vehicle
while pushing the button.

When Starting Your Vehicle
The selector lever cannot be
operated from the P position to any
other position without the brake
pedal being pressed. Be sure to
operate the lever while pressing the
brake pedal.
When Parking Your Vehicle
The key cannot be removed unless
the selector lever is securely placed
in the P position (key interlock

The shift lock system is a system for
safety to prevent incorrect operation
of the automatic transmission. Use it
correctly and drive safely.
If You Cannot Move the Selector
Lever from the P Position
Caution

operated from the P position to
any other position even after
performing the operation below
repeatedly, the shift lock system
may have a failure. Have the
vehicle inspected at your dealer.
If you cannot move the selector
lever from the P position after
starting the engine, perform the
following checks:
. Check that you are firmly
pressing the brake pedal. When
the brake pedal is not pressed,
the shift lock system operates
and the selector lever cannot be
shifted from P to any other
position.
. Check if the area where your

vehicle or its equipment. If you
have any questions about
carrying out some service, have
the work done by a skilled
technician.
To prevent personal injury, keep
hands, tools and clothing clear of
the engine cooling fan when the
engine is running.
The engine, exhaust pipe and
radiator will be hot immediately
after the vehicle is driven. Be
careful around these parts to
prevent burns. Perform all checks
when the engine is cold.
Do not perform work near an
open flame or other heat sources.
Do not let the engine run in poorly
ventilated garages or sheds. This
could cause carbon monoxide
poisoning.(Continued)
Warning (Continued)
Performing maintenance work on
a truck or chassis can be
dangerous. In trying to do some
jobs, you can be seriously injured.
Do your own maintenance work
only if you have the required
know-how and the proper tools
and equipment for the job. If you
have any doubts, contact your
dealer.
You and others could be seriously
injured.
For gasoline vehicles, pull firmly on
the parking brake lever and put the
transmission in neutral. Move the
selector lever to “P”and make sure
the shift indicator displays "P".
For diesel vehicles, pull firmly on the
parking brake lever and move the
selector lever to "P" and make sure
the shift indicator displays "P".
Make sure to turn off the engine and
remove the key from the engine
control switch before performing any
checks. Select a place with a solid and level
surface to perform the checking and
maintenance work. Make sure to
chock the wheels. It would be very
dangerous if the vehicle started

then disconnect the negative cable
from the negative terminal on
battery. If the negative cable is
disconnected within 3 minutes, the
engine control module may
malfunction.
For gasoline vehicles, when working
on the fuel line or fuel pump,
remove the fuel tank filler cap. The
fuel system is under pressure and
the fuel will overspill unless the
pressure is relieved, possibly
leading to combustion or a fire.

Vehicle Care 339
Cooling efficiency is compromised
when there is dirt or dust plugging
air passages in the radiator core
and charge air cooler core (diesel).
This can also cause corrosion of
these cores. Wash the radiator core
with tap water every 24 months.
Make sure to turn the engine off and
remove the key from the engine
control switch before cleaning
cores.
The engine, exhaust pipe, and
radiator will be hot immediately after
the vehicle is driven. Be careful
around these parts to prevent burns.
Clean the engine when it is cold.
Do not clean the radiator, charge air
cooler (diesel) and their surrounding
areas using water that is supplied
under high pressure. Doing so may
cause damage.
When cleaning the radiator core (1)
and charge air cooler core (2) , do
not crush or damage the fins (3).
The fins are very fragile so be
careful not to bend them out of
shape. If they become deformed,
their cooling efficiency will be
impaired. Before cleaning, take
steps to ensure that no water will
splash onto the surrounding
electrical components and wires.
If stubborn dirt still remains even
after the radiator core and charge
air cooler core (diesel) have been
cleaned, have the vehicle inspected
and serviced.
Corrosion Protection
Your vehicle has been designed and
built to resist corrosion. Special
materials and protective finishes
were used on most parts of your
vehicle when it was built to help
maintain good appearance,
strength, and reliable operation.
However, some parts which
normally are not visible (such as
those under the vehicle and under
the hood) are such that surface rust
will not affect their reliability. So
corrosion protection is not needed
or used on these parts.
Sheet Metal Damage
If your vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to the parts repaired or
replaced so that corrosion protection
is restored. (Also see "Finish
Damage" which follows.)
Foreign Material Deposits
Calcium chloride and other salts,
ice-melting agents, road oil and tar,
tree sap, bird droppings, chemicals
