24 In Brief
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.

If there is a decrease in the Remote
Keyless Entry (RKE) operating
range:
. Check the distance. The
transmitter may be too far from
the vehicle.
. Check the location. Other
vehicles or objects may be
blocking the signal.
. Check the transmitter's battery.
See “Replacing the Battery in
the Remote Control Unit” later in
this section.
. If the transmitter is still not
working correctly, see your
dealer or a qualified technician
for service.
Remote Keyless Entry

The keyless entry system allows
you to lock/unlock the doors by
simply pressing the remote control
button rather than inserting the key
into the lock.
The remote control unit works within
a 10 m (33 ft) radius of the cab
center as indicated in the figure.
The actual distance over which the
unit operates may vary depending
on conditions.

system causes the right and left turn
signal lights to simultaneously flash
once upon receiving the signals
from the remote control unit.
Should you lose the remote control
unit, please contact your dealer.
After locking the doors using the
remote control unit, be sure to
check that they are locked by
pulling the door handles.
Avoid getting water on the remote
control unit, dropping it, hitting it
against another object, or stepping
on it; otherwise, the remote control
unit could malfunction.
Do not leave the remote control unit
on the dashboard or any other
surface where the unit might be
exposed to high temperatures
(exceeding 60°C/140°F). Doing so
may result in shorter battery life or
malfunction of the remote
control unit.
If the keyless entry system fails to
operate normally, lock and unlock
the doors using the key and have
the system inspected by your
dealer.The lock or unlock buttons on the
remote control unit must be fully
pressed for more than 1 second
to work.
If you do not open any doors within
about 30 seconds after pressing the
unlock button to unlock the doors,
the automatic locking function of the
system will lock the doors again to
prevent theft.
In areas near a TV tower, electric
power plant, radio station, etc. or
under any conditions involving
strong electrical disturbances, the
remote control unit operating range
might change or the keyless entry
system might not work.
The keyless entry system does not
operate in the following cases:
.
The engine control switch is in
the "ON" position.
. The key is inserted in the engine
control switch.
. One of the doors is open.Replacing the Battery in the
Remote Control Unit
When the battery runs down,
replace it. Battery life is

{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
Vehicle
Carefully check that the area around
the vehicle is safe, hold the grip (1),
and place your foot on the step (2)
when getting in or out of the vehicle.
{Warning
When getting in or out of the
vehicle, make sure you use the
step and grips to support yourself (Continued)
Warning (Continued)
at 3 points. It is very dangerous to
stand on the tire or wheel when
getting in or out of the vehicle.
Furthermore, do not try to jump in
or out of the vehicle, as doing so
could cause unexpected
accidents or injuries.
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.
Rain and snow can cause the
step to become very slippery.
Therefore, always remove snow
and ice from your shoes and the
step, and be careful not to slip
when getting in and out of the
vehicle.(Continued)

Vehicle Security
Guard Against Theft
Your new vehicle has many features
to help prevent theft of the vehicle,
its equipment and contents. But
these anti-theft features depend
upon you to work.
The time to be most on guard is
when leaving the vehicle:
.Park in a lighted spot when
you can.
. Turn the engine control switch to
"LOCK" and remove the key.
This locks the switch and the
steering controls. The selector
lever is not locked.
. Keep items that may appear to
be of value out of sight and
locked up when possible.
. Fully close all windows and lock
all doors.
Exterior Mirrors
Mirrors
Sit in the correct driving position
with the seat adjusted properly.
Then, check each mirror to ensure
that a proper view of the rear and
sides of the vehicle are provided.
Make adjustments and clean mirrors
if necessary.
Outside Rearview Mirrors
After properly adjusting your seat for
proper driving position, adjust the
mirrors so that they provide
adequate views for checking the
rear and the sides of the vehicle.
Adjust the outside rearview mirrors
by hand before vehicle operation.
This helps you determine the
location of objects seen in the
mirror. If the outside mirror fogs up,
warm up the outside rearview
mirror's face to defog.
See Heated Mirrors 034.

{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.
