98 STARTING AND OPERATING

AFTER STARTING

The idle speed is controlled automatically, and it will
decrease as the engine warms up.

ENGINE BREAK-IN RECOMMENDATIONS

A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
Brief full-throttle acceleration within the limits of local
traffic laws contributes to a good break-in. Wide-open
throttle acceleration in low gear can be detrimental and
should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur
page 261.
CAUTION!
Never use non-detergent oil or straight mineral oil in
the engine or damage may result.
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 fea-
ture in the Customer Programmable Features sec-
tion of the Uconnect settings.
The parking brake switch is located on the instrument
panel to the left of the steering wheel (below the head-
lamp 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
Warning 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 Warning 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 extinguish
upon releasing the switch.
If the Auto Park Brake feature is enabled, the parking
brake will automatically engage whenever the transmis-
sion is placed into PARK, when the ignition is turned
OFF. If your foot is on the brake pedal, you may notice a
small amount of brake pedal movement while the park-
ing 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 disen-
gaged, the BRAKE Warning Light in the instrument clus-
ter and the LED indicator on the switch will extinguish.
