LUSTER DESCRIPTIONS

1. Speedometer

Indicates vehicle speed.
2. Temperature Gauge
The temperature gauge shows engine
coolant temperature. Any reading within the
normal range indicates that the engine
cooling system is operating satisfactorily.
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. 3. Tachometer
Indicates the engine speed in revolutions
per minute (RPM x 1000).
4. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the Keyless Push Button
Ignition is in the ON/RUN position.
 The fuel pump symbol points to
the side of the vehicle where the
fuel door is located.
NOTE:The Instrument Cluster Warning Indicators will illu -
minate briefly for a bulb check when the ignition is
first cycled.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. It is recommended to call an authorized
dealer for service if your vehicle overheats
Ú page 346.
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.

INSTRUMENT CLUSTER DISPLAY
Depending on your vehicles trim level, features
and options may vary.
Your vehicle will be equipped with an instrument
cluster display, which offers useful information to
the driver. With the ignition in the OFF mode, opening/closing of a door will activate the display
for viewing, and display the total miles, or
kilometers, in the odometer. Your instrument
cluster display is designed to display important
information about your vehicle’s systems and
features. Using a driver interactive display located
on the instrument panel, your instrument cluster
display can show you how systems are working and
give you warnings when they are not. The steering
wheel mounted controls allow you to scroll through
the main menus and submenus. You can access
the specific information you want and make
selections and adjustments.

Oil Change Required

Your vehicle is equipped with an
engine oil change indicator system.
The “Oil Change Required”
message will display in the
instrument cluster display for five seconds after a
single chime has sounded, to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means
the engine oil change interval may fluctuate,
dependent upon your personal driving style.

Unless reset, this message will continue to display
each time the ignition is placed in the ON/RUN
position. To turn off the message temporarily, push
and release the OK or arrow buttons. To reset the
oil change indicator system (after performing the
scheduled maintenance), refer to the following
procedure.

chime will sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how much oil
is in the engine. The engine oil level must be
checked under the hood.
Oil Temperature Warning Light

indicate the engine oil temperature is
high. If the light turns on while driving,
stop the vehicle and shut off the engine
as soon as possible. Wait for oil temperature to
return to normal levels.
Rear Seat Belt Reminder Warning Light —
If Equipped
This light indicates when a rear seat belt
is unbuckled in the second row. When
the ignition is first placed in the ON/RUN
position, and if a seat belt in the second
row is unbuckled, a light corresponding to the
specific seat will turn on in the upper right portion of the instrument cluster display, momentarily
replacing the configurable corner information. If a
second row seat belt that was buckled at the start
of the trip is unbuckled, the Rear Seat Belt

STARTING AND OPERATING123
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
and not interpreted as a problem. Please check
your oil level with the engine oil indicator often
during the break-in period. Add oil as required.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)

Your vehicle is equipped with an EPB that offers
simple operation, and some additional features that
make the parking brake more convenient and useful.

The parking brake is primarily intended to prevent
the vehicle from rolling while parked. Before
leaving the vehicle, make sure the parking brake is
applied. Also, be certain to leave the transmission
in PARK.
You can engage the parking brake in two ways:
Manually, by applying the parking brake switch.
Automatically, by enabling the Auto Park Brake
feature in the Customer Programmable
Features section of the Uconnect settings. The parking brake switch is located on the
instrument panel to the left of the steering wheel
(below the headlamp switch).

Electric Park Brake Switch

To apply the parking brake manually, pull up on the
switch momentarily. You may hear a sound from
the back of the vehicle while the parking brake
engages. Once the parking brake is fully engaged,
the BRAKE telltale light in the instrument cluster
and an indicator on the switch will illuminate. If
your foot is on the brake pedal while you apply the
parking brake, you may notice a small amount of
brake pedal movement. The parking brake can be
applied even when the ignition switch is OFF but
the BRAKE telltale light will not illuminate,
however, it can only be released when the ignition
is in the ON/RUN position.
NOTE:The EPB Warning Light will illuminate if the EPB
switch is held for longer than 20 seconds in either
the released or applied position. The light will extin -
guish upon releasing the switch.
If the Auto Park Brake feature is enabled, the
parking brake will automatically engage whenever
the transmission is placed into PARK. If your foot is
on the brake pedal, you may notice a small amount
of brake pedal movement while the parking brake
is engaging.
The parking brake will release automatically when
the ignition is ON, the transmission is in DRIVE or
REVERSE, the driver seat belt is buckled, and an
attempt is made to drive away.
To release the parking brake manually, the ignition
switch must be in the ON/RUN position. Put your
foot on the brake pedal, then push the EPB switch
down momentarily. You may hear a sound from the
back of the vehicle while the parking brake
disengages. You may also notice a small amount of
movement in the brake pedal. Once the parking
brake is fully disengaged, the BRAKE telltale light
in the instrument cluster and the LED indicator on
the switch will extinguish.CAUTION!
Never use non-detergent oil or straight mineral
oil in the engine or damage may result.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indicator
system will remind you that it is time to take your
vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent short-trips,
trailer tow, extremely hot or cold ambient
temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is
displayed. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for fleet
customers.
Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look for
unusual wear or damage.
Check the fluid levels of the coolant reservoir,
brake master cylinder and fill as needed.
Check function of all interior and exterior lights.
