134 STARTING AND OPERATING
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 354.
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

ARK

RAKE
(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.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.
