84 Instruments and Controls
Malfunction Indicator
Lamp (Check Engine
Light)
This light should come on to show
that it is working when the engine
control switch is turned to the ON
position, and then should go out
after the engine is started.
If this light stays on or comes on
while the engine is running, it
indicates a malfunction with the
engine electronic emission control
system. Avoid driving at high
speeds and have the vehicle
inspected by your dealer.
If this light comes on when the fuel
tank is empty, you do not need to
have your vehicle serviced. See
Running Out of Fuel (Diesel)0238. If this light comes on intermittently
or continuously while driving,
service is required. Even if the
vehicle is drivable and does not
require towing, see your dealer as
soon as possible. Continued driving
without having the system serviced
could cause damage to the
emission control system. It could
also affect fuel economy and
drivability.Service Vehicle Soon
Light
This light comes on briefly when the
engine control switch is in the ON
position, but the engine is not
running, as a check to show the
light is working. It should go out
when the engine is started.
If the light stays on, or comes on
while driving, the vehicle control
system may be malfunctioning. Take
the vehicle to your dealer for service
as soon as possible.

Instruments and Controls 91
Engine Shutdown
Warning Light
The Engine Shutdown Warning light
comes on briefly when the engine
control switch is turned to the ON
position, as a check to show the
light is working. The light turns off
when the engine is started.
This light will come on when the
engine alarm and automatic
shutdown system is active. See
Engine Alarm and Automatic
Shutdown (Diesel Only)0174.
Reduced Engine Power
Light
This light comes on briefly when the
engine control switch is turned to
the ON position, and then should go
out after the engine is started.
Diesel Engines
If this light comes on while the
engine is running, it indicates power
is being reduced due to one or more
of the following conditions:
.
Malfunction of the engine or
exhaust electronic control
system.
. DEF level is too low or empty.
If this light comes on with the
malfunction indicator lamp, see your
dealer immediately. If this light comes on with the Refill
Diesel Exhaust Fluid (DEF) warning
light and the DEF warning light, refill
DEF as soon as possible.
See
“Refill Diesel Exhaust Fluid
(DEF) Warning Light” underDriver
Information Center (DIC) (Diesel
Only) 093.
See Malfunction Indicator Lamp
(Check Engine Light) 084 and
Diesel Exhaust Fluid (DEF) Warning
Light 090.
Gas Engines
If this light comes on while the
engine is running, this means the
engine is overheating and in
overheat protection mode. The
overheat protection mode alternates
firing groups of cylinders in order to
prevent engine damage. In this
mode, the engine loses power and
performance. This operating mode
allows your vehicle to be driven to a
safe place in an emergency. Driving
extended miles (km) and/or towing a
trailer in the overheat protection
mode should be avoided.

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
