OPERATING TIPS
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect against
engine overheating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Ú page 265.
Window Fogging

Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower
speed. Do not use the Recirculation mode without A/C
for long periods, as fogging may occur.

Outside Air Intake
Make sure the air intake, located directly in front of
the windshield, is free of obstructions, such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.

GETTING TO KNOW YOUR INSTRUMENT PANEL55
INSTRUMENT CLUSTER DESCRIPTIONS

1. Tachometer

This gauge measures engine revolutions
per minute (RPM x 1000). Before the
pointer reaches the red area, ease up on
the accelerator to prevent engine damage.
2. Instrument Cluster Display
When the appropriate conditions exist, this
display shows instrument cluster display
messages Ú page 56.
Odometer/Trip Odometer Display Area

US Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser
the correct mileage that the vehicle has been driven.
If your odometer needs to be repaired or serviced,
the repair technician should leave the odometer
reading the same as it was before the repair or
service. If the technician cannot do so, then the
odometer must be set at zero, and a sticker must be
placed in the door jamb stating what the mileage
was before the repair or service. It is a good idea
for you to make a record of the odometer reading
before the repair/service, so that you can be sure
that it is properly reset, or that the door jamb sticker
is accurate if the odometer must be reset at zero.

Gear Selector Status (PRND)
The gear selector status “P, R, N, D, 1, 2, 3, 4,
etc.” are displayed indicating the gear selector
position. Telltales “1, 2, 3, 4, etc.” indicate the
manual mode has been engaged and the gear
selected is displayed Ú page 81.
3. 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
or up mountain grades. It should not be
allowed to exceed the upper limits of the
normal operating range. 4. Fuel GaugeThe pointer shows the level of fuel in the
fuel tank when the ignition switch is in the
ON/RUN position.
 The fuel pump symbol points to
the side of the vehicle where the
fuel door is located Ú page 122.
5. Speedometer
Indicates vehicle speed.
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.
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.

78STARTING 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.

While cruising, 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. For the recommended viscosity and
quality grades see Úpage 273.
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 that 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 slight sound
from the back of the vehicle while the parking brake
engages. Once the park 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 extin -
guish upon releasing the switch.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

23_VF_OM_EN_USC_t.book Page 78

80STARTING AND OPERATING
In the unlikely event of a malfunction of the EPB
system, a yellow EPB Warning Light will illuminate.
This may be accompanied by the Brake Warning
Light flashing. In this event, urgent service of the
EPB system is required. Do not rely on the parking
brake to hold the vehicle stationary.
Auto Park Brake
The Electric Park Brake (EPB) can be programmed
to be applied automatically whenever the vehicle is
at a standstill and the automatic transmission is
placed in PARK. Auto Park Brake is enabled and
disabled by customer selection through the
Customer Programmable Features section of the
Uconnect Settings Ú page 145.
Any single Auto Park Brake application can be
bypassed by pushing the EPB switch to the release
position while the transmission is placed in PARK.
SafeHold
SafeHold is a safety feature of the Electric Park
Brake (EPB) system that will engage the parking brake automatically if the vehicle is left unsecured
while the ignition is in ON/RUN.
The parking brake will automatically engage if all of
the following conditions are met:
The vehicle is at a standstill.
There is no attempt to press the brake pedal
and accelerator pedal.
The occupant status changed to unoccupied.
The driver door is open.
SafeHold can be temporarily bypassed by pushing
the EPB switch while the driver door is open. Once
manually bypassed, SafeHold will be enabled
again once the vehicle reaches 12 mph (20 km/h)
or the ignition is turned to the OFF position and
back to ON again.
Brake Service Mode
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs
for which you have the knowledge and the right
equipment. You should only enter Brake Service
Mode during brake service.
When servicing your rear brakes, it may be
necessary for you or your technician to push
the rear piston into the rear caliper bore. With
the Electric Park Brake (EPB) system, this can
only be done after retracting the EPB actuator.
Fortunately, actuator retraction can be done easily
by entering the Brake Service Mode through the Uconnect Settings in your vehicle. This
menu-based system will guide you through the
steps necessary to retract the EPB actuator in
order to perform rear brake service.
Service Mode has requirements that must be met
in order to be activated:
The vehicle must be at a standstill.
The parking brake must be unapplied.
The transmission must be in PARK or NEUTRAL.
While in Service Mode, the EPB Warning Light will
flash continuously while the ignition is in ON/RUN.
When brake service work is complete, the following
steps must be followed to reset the park brake
system to normal operation:
Ensure the vehicle is at a standstill.
Press the brake pedal with moderate force.
Apply the EPB Switch.
WARNING!
Driving the vehicle with the parking brake
engaged, or repeated use of the parking brake
to slow the vehicle, may cause serious damage
to the brake system. Be sure the parking brake
is fully disengaged before driving; failure to do
so can lead to brake failure and a collision.
WARNING!
You can be badly injured working on or around
a motor vehicle. Do only that service work for
which you have the knowledge and the right
equipment. If you have any doubt about your
ability to perform a service job, take your vehicle
to a competent mechanic.
