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.

center as indicated in the figure.
The actual distance over which the
unit operates may vary depending
on conditions.

Keys, Doors, and Windows 27
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
approximately two years.

Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.Some warning lights come on briefly
when the engine is started to
indicate they are working. When
one of the warning lights comes on
and stays on while driving, or when
one of the gauges shows there may
be a problem, check the section that
explains what to do. Waiting to do
repairs can be costly and even
dangerous.
For safety reasons, do not place
packages, tools, or other items in
the driver
’s area that may restrict
access to the controls or sight of the
gauges.
