162 GETTING TO KNOW YOUR INSTRUMENT PANEL
Base / Midline Instrument Cluster Descriptions
1. Tachometer• Indicates the engine speed in revolutions per minute(RPM x 1000).
2. Voltmeter
• When the vehicle is in the RUN state, the gauge indi -
cates the electrical system voltage. The pointer should
stay within the normal range if the battery is charged.
If the pointer moves to either extreme left or right and
remains there during normal driving, the electrical
system should be serviced.
NOTE:
In vehicles equipped with Stop/Start, a reduced voltage may
be present during an Autostop.
3. Instrument Cluster Display
• When the appropriate conditions exist, this displayshows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information. 4. Oil Pressure Gauge
• The pointer should always indicate the oil pressurewhen the engine is running. A continuous high or low
reading under normal driving conditions may indicate
a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
NOTE:
In vehicles equipped with Stop/Start, an oil pressure indica -
tion of zero is normal during an Autostop.
5. Speedometer
• Indicates vehicle speed.
6. Fuel Gauge
• The pointer shows the level of fuel in the fuel tankwhen the ignition is in the ON/RUN position.
• The fuel pump symbol points to the side of the vehicle where the fuel door is located.

3. Speedometer• Indicates vehicle speed.
4. Fuel Gauge
• The pointer shows the level of fuel in the fuel tankwhen the ignition is in the ON/RUN position.
• The fuel pump symbol points to the side of the vehicle where the fuel door is located.
5. Temperature Gauge
• The pointer shows engine coolant temperature. Thepointer positioned within the normal range indicates
that the engine cooling system is operating satisfacto -
rily.
• The pointer will likely indicate a higher temperature when driving in hot weather, up mountain grades, or
when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.WARNING!
A hot engine cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant. You
may want to call an authorized dealer for service if your
vehicle overheats. Refer to “Cooling System Pressure
Cap” in “Servicing And Maintenance” for further
information if you decide to look under the hood.
CAUTION!
Driving with a hot engine cooling system could damage
your vehicle. If the temperature gauge reads “H,” pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into
the normal range. If the pointer remains on the “H,” turn
the engine off immediately and call an authorized dealer
for service.

Optimal conditions for completing the process are achieved by trav-
eling at 37 mph (60 km/h) with engine speed above 2,000 rpm.

When this symbol switches on, it does not indicate a vehicle
failure and thus it should not be taken to a workshop. On
some versions, together with the symbol switching on, the
display shows a dedicated message.
— Low Diesel Exhaust Fluid (DEF) Indicator Light — If
Equipped
The Low Diesel Exhaust Fluid (DEF) Indicator will illumi -
nate if the vehicle is low on Diesel Exhaust Fluid (DEF). Refer
to “Starting And Operating” for further information.
— Low Diesel Exhaust Emissions Additive (UREA)
Indicator Light — If Equipped
The Low Diesel Exhaust Emissions Additive (UREA) indi -
cator light illuminates when the UREA level is low.

Fill the UREA tank as soon as possible with at least 1.3 gallons
(5 liters) of UREA.

If filling the tank is done with a remaining range of UREA in
the tank equal to zero, you may need to wait two minutes
before starting the vehicle.
Refer to “Starting And Operating” for further information. — Water In Fuel Indicator Light — If Equipped
The “Water In Fuel Indicator Light” will illuminate when
there is water detected in the fuel filter. If this light remains
on, DO NOT start the vehicle before you drain the water
from the fuel filter to prevent engine damage, and please see
an authorized dealer.
— Wait To Start Light — If Equipped
This indicator light will illuminate for approximately two
seconds when the ignition is turned to the RUN position. Its
duration may be longer based on colder operating condi -
tions. Vehicle will not initiate start until telltale is no longer
displayed
CAUTION!
The presence of water in the fuel system circuit may
cause severe damage to the injection system and
irregular engine operation. If the indicator light is
illuminated, contact an authorized dealer as soon as
possible to bleed the system. If the above indications
come on immediately after refuelling, water has
probably been poured into the tank: switch the engine
off immediately and contact an authorized dealer.

SAFETY 263
(Continued)
Your vehicle may also be designed to perform any of these
other functions in response to the Enhanced Accident
Response System:
• Turn off the Fuel Filter Heater, Turn off the HVAC BlowerMotor, Close the HVAC Circulation Door
• Cut off battery power to the: • Engine
• Electric Motor (if equipped)
• Electric power steering
• Brake booster
• Electric park brake
• Automatic transmission gear selector
• Horn
• Front wiper
• Headlamp washer pump
NOTE:
After an accident, remember to cycle the ignition to the STOP
(OFF/LOCK) position and remove the key from the ignition
switch to avoid draining the battery. Carefully check the
vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel tank before
resetting the system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical devices (e.g. headlights) after an accident, reset the system by following
the procedure described below. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be changed
from ignition START or ON/RUN to ignition OFF. Carefully
check the vehicle for fuel leaks in the engine compartment
and on the ground near the engine compartment and fuel
tank before resetting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag system could cause it to fail when you need it. You could be injured
if the air bag system is not there to protect you. Do not
modify the components or wiring, including adding
any kind of badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the instru -
ment panel. Do not modify the front bumper, vehicle
body structure, or add aftermarket side steps or
running boards.

STARTING AND OPERATING 403
REFUELING THE VEHICLE
The fuel filler is located behind the fuel filler door, on the left
side of the vehicle.
There is no fuel filler cap. Two flapper doors inside the pipe
seal the system.CAUTION!
• To avoid vehicle damage, Surround View should only be used as a parking aid. The Surround View camera is
unable to view every obstacle or object in your drive
path.
• To avoid vehicle damage, the vehicle must be driven slowly when using Surround View to be able to stop in
time when an obstacle is seen. It is recommended that
the driver look frequently over his/her shoulder when
using Surround View.
WARNING!
• Never have any smoking materials lit in or near the vehicle when the fuel door is open or the tank is being
filled.
• Never add fuel when the engine is running. This is in violation of most state and federal fire regulations and
may cause the MIL to turn on.
• A fire may result if gasoline is pumped into a portable container that is inside of a vehicle. You could be
burned. Always place gas containers on the ground
while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top off”
the fuel tank after filling.
