WARNING
■When starting the engine
Always start the engine while sitting in the driver's seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution when driving
Do not turn the engine switch to the “LOCK” position while driving. If, in an
emergency, you must turn the engine off while the vehicle is moving, turn the
engine switch only to the “ACC” position to stop the engine. An accident may
result if the engine is stopped while driving.
CAUTION
■To prevent battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long periods
of time without the engine running.
■ When starting the engine
●Do not crank the engine for more than 10 seconds at a time. This may
overheat the starter and wiring system.
If the engine does not start, turn the engine switch to the “LOCK” position
and try to start the engine again after waiting for 10 seconds or more.
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by your SUBARU dealer immediately.
● Vehicles with an automatic transmission: Do not shift the select lever while
the starter is operating.

Drive information (page 3)
Engine coolant temperature
gauge
Displays the engine coolant tem-
perature.
If the engine coolant temperature
gauge needle/indicator enters the
red zone, a buzzer will sound and
a warning message will be dis-
played.
Engine oil temperature gauge
Displays the engine oil tempera-
ture.
Vo l t m e t e r
Displays the charging voltage.
As voltage displayed may
be different from the actual
battery voltage, use the volt-
meter as a guideline.
●Pressing and holding will turn the range value display on the
engine coolant temperature gauge display on/off.

G-force display
● Depending on the vehicle usage conditions , the brake fluid pressure dis-
play may not reach its maximum reading even though the brake pedal is
fully depressed.
● If a battery terminal is disconnected and reconnected, the steering
amount display may be disabled temporarily. After driving the vehicle for
a while, the display will be enabled.
■ Suspension of the settings display
● The settings cannot be changed while driving. When changing settings,
park the vehicle in a safe place.
● If a warning message is displayed, operation of the settings display will
be suspended.
■ Using the stopwatch
If the engine is stopped while the stopwatch is operating, the stopwatch will
stop and the time up to that point will be recorded.
■ Outside temperature display
● In the following situations, the correct outside temperature may not be
displayed.
• When the vehicle is very hot, such as when under the sun.
• When the vehicle is idling or being driven at low speeds such as in a
traffic jam or when the engine is stopped and then restarted immedi-
ately afterward.
• When the actual outside temperature is outside of the indicator range.
● If “ − − ” is displayed for approximately 1 minute or more or if the outside
temperature is not displayed, the system may be malfunctioning. Have
the vehicle inspected by your SUBARU dealer.
■ Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.

WARNING
■Caution for use while driving
●When operating the multi-information display while driving, pay extra
attention to the safety of the area around the vehicle.
● Do not look continuously at the multi-information display while driving as
you may fail to see pedestrians, objects on the road, etc. ahead of the
vehicle.
■ The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This l ag could cause the driver to down-
shift again, causing rapid and exce ssive engine braking and possibly an
accident resulting in death or injury.
■ Cautions during setting up the display
As the engine needs to be running during setting up the display, ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area
such as a garage, exhaust gases including harmful carbon monoxide (CO)
may collect and enter the vehicle. This may lead to death or a serious health
hazard.
CAUTION
■While setting up the display
To prevent battery discharge, ensure that the engine is running while setting
up the display features.

■
Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number
of passengers and the loading condition of the vehicle to ensure that the
headlights do not interfere with other road users.
■ Windshield wiper-linked automatic headlights
When the headlight switch is in , if the windshield wipers operate for
approximately 10 seconds, the headlights will turn on automatically. (If the
windshield wipers are operated due to oper ation of the windshield washers,
the headlights will not turn on automatic ally.) In this case, the headlights will
automatically turn off approximately 60 seconds after the windshield wipers
stop operating.
■ Battery-saving function
In the following conditions, the headlights and the other remaining lights will
go off automatically after 20 minutes in order to prevent the vehicle battery
from being discharged:
● The headlights and/or tail lights are on.
● The key is removed from the engine switch (vehicles without a keyless
access with push button start system) or the push-button ignition switch
is turned off (vehicles with a keyless access with push button start sys-
tem).
● The light switch is in , or .
This function will be canceled in any of the following situations:
● When the engine switch is turned to the “ON” position (vehicles without a
keyless access with push button start system) or the push-button ignition
switch is turned to “ON” mode (vehicles with a keyless access with push
button start system)
● When the light switch is operated
● When the door is opened or closed
■ Customization that can be configured at your SUBARU dealer
Settings (e.g. light sensor sensitivity) can be changed.

CAUTION
■How to use the rear view camera
●When washing your vehicle with a high-pressure washer, do not allow the
water to contact the rear view camera directly. Entry of water into the cam-
era lens may result in condensation on the lens, malfunction, fire or elec-
tric shock.
● Since the rear view camera is a precision device, do not subject it to
strong impacts. Otherwise, malfunction, fire or electric shock may occur.
● If mud or snow sticks to or is frozen on the rear view camera, very carefully
remove it. Otherwise, damage to the rear view camera may cause a fire or
electric shock. Pour water or lukewarm water over the rear view camera to
remove mud and ice, and wipe it with a soft, dry cloth.
● When replacing a fuse, be sure to use a fuse with the specified rating. Use
of a fuse with a different rating may result in a malfunction.
● If the rear view camera is used for a long time while the engine is not run-
ning, the battery may become completely discharged.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■Pre-winter preparations
● Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Washer fluid
● Have a service technician inspect the condition of the battery.
● Have the vehicle fitted with four snow tires.
Make sure to install 4 tires that are of the specified size, and that
all 4 tires are the same for the following items:
•Size
• Circumference
• Speed symbol
• Load index
• Construction
• Manufacturer
• Brand (tread pattern)
• Degrees of wear
Also, make sure to use tire chains that match the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions.
● Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
