Additional owner information is given in separate publications.
ThisOwner’s Guidedescribes every option and model variant available
and therefore some of the items covered may not apply to your
particular vehicle. Furthermore, due to printing cycles it may describe
options before they are generally available.
Remember to pass on thisOwner’s Guidewhen reselling the vehicle. It
is an integral part of the vehicle.
Fuel pump and high voltage battery shut-off switches:In
the event of an accident the fuel pump shut-off switch may
automatically cut off the fuel supply to the engine and the high voltage
shut-off switch cuts off power from the high voltage battery. These
switches can also be activated through sudden vibration (e.g. collision
when parking). For information on resetting the fuel pump shut-off
switch and the high voltage battery shutoff switch, refer to theFuel
pump/high voltage shut-off switchesin theRoadside Emergencies
chapter.

Starting the vehicle
•The engine will start and run when you first turn the ignition key to
the start position.
•The engine cannot be started in the N (Neutral) position.
•Depending upon temperature and the high voltage battery’s state of
charge, the engine may shut off shortly after starting the vehicle; this
is a normal condition and you do not need to restart the vehicle. The
Ready Indicator Light in the instrument cluster will illuminate to
indicate the vehicle is running. For more Ready Indicator Light
information, refer toWarning lights and chimesin theInstrument
Clusterchapter.
DRIVING THE VEHICLE
Starting Out:
Under normal operation with the vehicle at operating temperature, the
engine will start automatically as you accelerate. Sometimes the engine
will start immediately as you begin moving, while other times the vehicle
will obtain a speed of up to 25 mph (40 km/h) before the engine starts.
You may hear and feel the engine starting as you transition from
electrical to hybrid (gas engine on) operation. This is a normal condition.
These are some of the conditions that may cause engine start-up:
•High voltage battery re-charge is required.
•Driver acceleration demands exceed electric motor capability.
•Outside air temperature is overly hot or cold.
•Certain climate system modes of operation.
•If you are starting up hill or accelerating quickly, the engine will start
immediately as operating conditions require additional power.
Note:If the high voltage battery is very cold or very hot, the engine may
operate more than under normal conditions, and vehicle performance
may be temporarily reduced. This is a normal condition.
Transmission operation
•Your vehicle does not shift like a conventional vehicle. You may feel
transitions between the various operating modes of the hybrid system,
but no actual shifting occurs. For more information about transmission
operation, refer toUnderstanding the gearshift positions of the
electronically-controlled Continuously Variable Transaxle (eCVT)
in theDrivingchapter.

Stopping the vehicle
•The vehicle’s engine may shut off as you come to a stop; this is a
normal condition and helps to conserve fuel. You do not need to
restart the vehicle.
Neutral operation
•The vehicle does not charge the high voltage battery in the N
(Neutral) position. Do not idle the vehicle in N (Neutral) for extended
periods as this will discharge the high voltage battery.
Low gear operation
•In L (Low) gear, you may feel an increased sensation of engine
braking as you remove your foot from the accelerator. L (Low) gear
can be helpful when driving down an incline; unlike in a conventional
vehicle, L (Low) does not offer an advantage over D (Drive) in uphill
or off-road driving conditions.
Reverse operation
•Vehicle speed is limited to 22 mph (35 km/h) while operating in R
(Reverse) gear.
MARINER HYBRID UNIQUE OPERATING CHARACTERISTICS
•You may hear some unique sounds from a hybrid vehicle. The Mariner
Hybrid is equipped with a high voltage battery air conditioning system
in the rear of the vehicle which cools the high voltage battery in order
to ensure high voltage battery life and optimize performance. You may
hear a slight clunk or tap noise as the vent door operates, as well as a
fan noise in the rear of the vehicle; this noise is the high voltage
battery cooling fan. The high voltage battery cooling may also continue
to operate for short durations after the vehicle has been turned off.
These vehicle conditions and noises are normal and do not require
service.
•You may hear a pumping sound when you enter the vehicle or a
venting sound a few minutes after parking the vehicle. This is due to
charging and discharging of the hydraulic portion of the regenerative
braking system.
•You may hear a slight whine or whistle when operating your vehicle.
This noise could occur at idle, and during cruising and accelerating; it
is caused by the normal operation of electrical generator in the hybrid
system.

•The Mariner Hybrid’s hydraulic brake system used for regenerative
braking is different from other vehicles. The noise from the ABS pump
motor and the brake pedal pulsation are much less than on vehicles
with conventional ABS. Noise and pedal pulsation during ABS may not
be noticed. For more information about braking, refer toBrakingin
theDrivingchapter.
•The engine speed in an Mariner Hybrid is not directly tied to the
vehicle speed. Under certain conditions, the engine speed may appear
much higher than that of a conventional automobile. This is a normal
condition and is caused by engine speed optimization to maximize fuel
economy.
•During certain events (such as vehicle servicing) your low voltage
(underhood) battery may become disconnected or disabled. When this
occurs, and after reconnecting the low voltage (underhood) battery
and driving the vehicle, the engine may continue to operate for 3-5
seconds after the key is turned to the 1 (LOCK) position. This is a
normal condition, as the vehicle’s computers are relearning the
operating characteristics of your particular engine in order to operate
it at maximum efficiency.
•The high voltage battery may go through a self-reconditioning process
from time to time; these events optimize high voltage battery
performance. You may notice slight changes to driveability during the
reconditioning process. This is a normal condition.
•If the vehicle is left inoperative for over 31 days, it may be necessary
to jumpstart the vehicle. For more information, refer toJump
starting your vehicle (Low voltage [underhood] battery only)in
theRoadside Emergencieschapter.
DRIVING TO OPTIMIZE FUEL ECONOMY
Fuel economy can be significantly impacted by your driving habits and
accessory usage. To optimize the fuel economy in your vehicle, please be
aware of the following vehicle functions which affect fuel economy:
A/C operation
•With the climate control system set to MAX A/C, defrost, or
defrost/floor mode (the orange graphics on your climate control), the
engine will typically run continuously, reducing fuel economy. Setting
the climate control system to A/C mode or A/C
mode also
reduces fuel economy, but in this case the A/C only operates when the
engine is already running due to other demands. Because the engine
does not run continuously, A/C and A/C
mode are more fuel
efficient than MAX A/C mode.
