Temporary Hood Repair
If the rear of the hood is raised, the
hood may be repositioned
temporarily if a towing service is not
available.
{Warning
Before beginning the procedure,
read all the instructions. Failure to
read and follow the instructions
could injure you or others, and
damage the vehicle.
{Warning
After the hood has lifted, the hood
hinge and latch area may be hot.
Do not touch the pedestrian
protection system components.
Allow the engine to cool before
attempting any repair.
{Warning
You or others could be injured
when the hood is lowered or
latched.
Be sure to keep fingers and other
body parts away from the edge of
the hood and fenders.
1. Place both hands on top of the right corner of the hood near
the windshield and push the
hood down quickly.
If the hood does not latch, push
down again with slightly more
force until the hood is latched
securely.
2. Repeat the previous step to latch the left side of the hood.
3. Pull up on the rear corners of the hood to make sure the
hood is latched securely and
will not lift.
{Warning
Do not drive the vehicle if the
hood is not securely latched at
both rear corners and the front
latch.
Operating your vehicle without the
hood securely latched can lead to
a collision resulting in damage to
your vehicle, damage to other
property, personal injury, or even
death.
4. Drive directly to a dealer for service. If you cannot go in for
service immediately, have the
vehicle towed.
Some noise will occur when
the vehicle is driven while the
hood is temporarily
repositioned.

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.

the open source software
information.
Speedometer
The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
For vehicles with the Stop/Start
system, when the ignition is on, the
tachometer indicates the vehicle
status. When pointing to AUTO
STOP, the engine is off but the
vehicle is on and can move. The
engine could auto start at any time.
When the indicator points to OFF,
the vehicle is off.
When the engine is on, the
tachometer will indicate the engine’s
revolutions per minute (rpm). The
tachometer may vary by several
hundred rpm’s, during Auto Stop
mode, when the engine is shutting
off and restarting.
Caution
If the engine is operated with the
rpm’s in the warning area at the
high end of the tachometer, the
(Continued)

vehicle could be damaged, and
the damage would not be covered
by the vehicle warranty. Do not
operate the engine with the rpm’s

Engine Oil Temperature
Gauge (Uplevel)

This gauge shows the engine oil
temperature.
If the gauge pointer moves into the
high end, it means that the engine
oil has overheated. If the vehicle
has been operated under normal
driving conditions, pull off the road,
stop the vehicle, and turn off the
engine as soon as possible.

This gauge shows the engine
coolant temperature.
If the gauge pointer moves toward
the warning area at the high end of
the gauge, the engine is too hot.
The engine coolant temperature
warning light comes on when the
engine is too hot. See Engine
Coolant Temperature Warning Light
(Uplevel) 0125.
This reading indicates the same
thing as the warning light. It means
that the engine coolant has
overheated. If the vehicle has been
operating under normal driving conditions, pull off the road, stop the
vehicle, and turn off the engine as
soon as possible. See
Engine
Overheating 0247.
Voltmeter Gauge
(Uplevel)
When the ignition is on, this gauge
indicates the battery voltage.
When the engine is running, this
gauge shows the condition of the
charging system. The gauge can
transition from a higher to lower or a
lower to higher reading. This is
normal. If the vehicle is operating

outside the normal operating range,
the charging system light comes on.
SeeCharging System Light 0119.
Readings outside the normal
operating range can also occur
when a large number of electrical
accessories are operating in the
vehicle and the engine is left idling
for an extended period. This
condition is normal since the
charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can only be driven for a
short time with the readings outside
the normal operating range. If the
vehicle must be driven, turn off all
accessories, such as the radio and
air conditioner, and unplug all
chargers and accessories.
Readings outside the normal
operating range indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.Seat Belt Reminders
Driver Seat Belt Reminder
Light
There is a driver seat belt reminder
light on the instrument cluster.
When the vehicle is started, this
light flashes and a chime may come
on to remind the driver to fasten
their seat belt. Then the light stays
on solid until the belt is buckled.
This cycle may continue several
times if the driver remains or
becomes unbuckled while the
vehicle is moving.
If the driver seat belt is buckled,
neither the light nor the chime
comes on.
Passenger Seat Belt Reminder
Light
There is a passenger seat belt
reminder light near the passenger
airbag status indicator. See
Passenger Sensing System 065.
When the vehicle is started, this
light flashes and a chime may come
on to remind passengers to fasten
their seat belt. Then the light stays
on solid until the belt is buckled.
This cycle continues several times if
the passenger remains or becomes
unbuckled while the vehicle is
moving.
If the passenger seat belt is
buckled, neither the chime nor the
light comes on.
The front passenger seat belt
reminder light and chime may turn
on if an object is put on the seat

outboard passenger frontal airbag
and knee airbag are allowed to
inflate.
If the word OFF, and the off symbol,
is lit on the airbag status indicator, it
means that the passenger sensing
system has turned off the front
outboard passenger frontal airbag
and knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light 0118 for more information,
including important safety
information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer.
If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the ignition is in
Service Mode. See Ignition
Positions 0176.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.
