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.

SAFETY305
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully depress
each pedal to check for interference with the
accelerator, brake, or clutch pedals then
re-install the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using
the floor mat fasteners by lightly pulling mat.
WARNING!
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.

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.
