.To reduce the risk of
personal injury, apply force
to the steering wheel to
make certain the steering
column is firmly locked
before driving. Also, do not
try to tilt or adjust the

Performance and
Maintenance
Driving for Better Fuel
Economy
Economical Driving
How you drive, where you drive and
when you drive all affect fuel
economy.
For diesel vehicles, driving too fast,
driving so slowly that the engine
knocks, driving with the exhaust
brake switched on all the time, and
frequently using the exhaust brake
to adjust your speed can lead to
poor fuel economy.
Drive at a constant speed as much
as possible. When accelerating,
increase your speed gently and
slowly, and up-shift early.
Maintain a constant cruising speed,
as traffic allows, and avoid sudden
stops.Frequent short trips, excessive
idling and use of the air conditioner
in cool weather when "Vent" would
provide adequate comfort, can all
lead to decreased fuel economy.
Warming up the engine for longer
than necessary, driving with the
vehicle overloaded and revving the
engine are a waste of fuel.
Overcooling of the engine not only
accelerates wear of the vital engine
parts but also hurts fuel economy.
The careful attention you give your
vehicle, as far as maintenance is
concerned, will also help fuel
economy.
Protection of Engine against
Overcooling
Overcooling of the engine not only
accelerates wear of the vital engine
parts but also hurts fuel economy.
Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) is used
with diesel engines to reduce the
amount of regulated emissionsproduced. The DEF system must be
maintained for the vehicle to run
properly.
DEF is not a fuel additive. For
refilling instructions, see
Diesel
Exhaust Fluid 0189. DEF should
not be mixed with or added to diesel
fuel. DEF freezes when exposed to
temperature below −11 °C (12 ° F).
Locating Diesel Exhaust Fluid
DEF can be purchased at a dealer.
It can also be purchased at
authorized vehicle and truck
dealerships. Additionally, some
diesel truck fueling stations or
retailers may have DEF for
purchase. See Recommended
Fluids and Lubricants 0349.
When the remaining level of DEF
becomes excessively low the DEF
gauge will change color from green
to amber. In addition, warning and
indicator lights will come on and
engine power will be reduced so the
vehicle speed will not exceed
89 km/h (55 MPH). See Diesel
Exhaust Fluid 0189.

{Warning
When changing the battery, use
only a battery of the same type as
the original battery, or an
equivalent. Otherwise, there is a
risk of explosion.
Do not place the battery in direct
sunlight, or near a fire or other
sources of heat.
Be sure to install the battery with
the "+" and "-" sides correctly
oriented. Incorrect installation will
result in leakage of chemicals
from inside the battery or other
operational problems.
You and others could be seriously
injured.
The battery life varies depending on
how the remote control unit is used.
The battery has reached its end of
life when the remote control unit
works intermittently or does not
work at all. Replace the battery as
soon as this happens.
Getting In and Out of the

Getting in or out of the vehicle
with oily or greasy hands or
shoes could cause you to slip.
Always thoroughly clean grease,
etc. from your hands and shoes
before getting in or out of the
vehicle.

Warning (Continued)
Exercise caution when opening or
closing doors, as strong winds or
steep slopes may cause doors to
open or close suddenly.
Do not hold parts other than the
grip when getting in or out of the

damage to the vehicle or injuries
to yourself or others.
You and others could be seriously
injured.
Door Locks
{Warning
Be sure to do the following
whenever you leave the vehicle:1. Fully engage the parkingbrake.
2. Stop the engine.
3. Lock the doors. (Continued)
Warning (Continued)
When you close the door after
sitting behind the wheel, check
that the door is fully closed.
Driving with any door ajar is very
dangerous.
Before opening the door when
climbing into or out of the cab,
carefully check all areas around
the vehicle for safety, especially
the area at the rear of the vehicle.
If you suddenly open a door
without checking the surrounding
area, the door could be hit by a
vehicle behind you or a
pedestrian.
Never leave the key in the
vehicle.
Tilt the cab only after fully closing
the doors.
To help reduce the risk of
personal injury in an accident,
always lock the doors when
driving. Along with using the seat
(Continued)
Warning (Continued)
belts properly, locking the doors
helps prevent people from being
thrown from the vehicle. It also
helps prevent unintended opening
of the doors and helps keep out
intruders.
You and others could be seriously
injured.
{Warning
To protect the child from the
danger of getting his/her hands
and head trapped, an adult must
open, close and lock the door for

{Warning
Before driving, be sure to adjust
the seat and mirrors to positions
that give you a correct driving
posture.
Do not adjust the outside mirrors
while operating the vehicle.
Adjust the mirrors when the
vehicle is stationary, not while the
vehicle is in motion.
When checking the rear of the
vehicle with mirrors, be careful
that this does not distract your
attention from the traffic ahead.
Outside mirrors may make the
vehicle behind you appear farther
away than it really is. Use these
mirrors very carefully until you are
able to correctly determine
distances from the images.(Continued)
Warning (Continued)
Keep the mirrors in mind when
passing another vehicle on a
narrow road, moving the vehicle
into a garage, or driving near
pedestrians.
Do not drive with the mirrors
folded.
You and others could be seriously
injured.
Heated Mirrors
If the outside rearview mirrors fog
up, press the outside rearview
mirror heater switch to defog them.
When the switch is pressed the
indicating light will illuminate. If the
switch is pressed once again, it will
switch to“OFF,”and the operation
indicating light will go out.
Do not use this switch while the
engine is shut down. Due to high
power consumption, the battery can
be discharged.
Turn off the switch as soon as
defogging is complete.

If you are traveling with a child,
do not leave the child alone in the
vehicle. If the child touches the
controls or equipment, an
accident could occur. (For
example, the vehicle could move
or a fire could start.) Also, the cab
inside could become dangerously
hot in hot weather.
{Warning
Before closing the windows, make
sure that there is no risk of a
hand, head, or anything else
being trapped in the moving
window.
You and others could be seriously
injured.
{Warning
Regardless of whether the vehicle
is moving or stationary, you must
never allow a child to put his/her
head, hands, or other body part
out of the window. Allowing such

because the child could hit an
obstacle.
You and others could be seriously
injured.
