Fuel gauge

When the ignition switch is at “ON”
position, the gauge indicates the
approximate quantity of the fuel
remaining in the tank.
Nearly full: needle at “F”
Nearly empty: needle at “E”
It’s necessary to keep 1/4 tank of fuel.
The needle moves when braking,

accelerating or making turns. This is
caused by the fuel moving in the tank.

Reminding of filling the fuel: if it

becomes yellow when needle at “E”,
please fill the fuel.

When you are driving on the slope or turning,
the fuel in the tank will be caused to swash.
Needle of fuel gauge would sway or warning
light of fuel quantity would usually be on
earlier.
When the ignition key is at “ON” position,
there is no malfunction even if needle of fuel
gauge is at “E”.

Engine coolant temperature gauge

The gauge indicates the engine coolant
temperature when the ignition switch
stays at “ON” position. Working
temperature of the engine varies with
weather and load of the engine.

If the needle moves into the red zone, your
engine is too hot. If you vehicle

F3/F3R OWNER’S MANUAL

- 73 -

overheats, park your vehicle and allow the
engine to cool.

Your vehicle may overheat during severe
operating condition, such as:
●

Driving up a long hill on a hot day.

●

Idling for a long period with the air
conditioning on in stop-and-go traffic.

●

Daggling other vehicles.

When the ignition switch is in “START”
position, there is no malfunction even if the
engine coolant temperature gauge needle
returns to “C”.

NOTICE

●

Do not remove the thermostat on the
engine cooling system as this may
cause the engine to overheat. The
thermostat is designed to control the
flow of coolant to keep the
temperature of the engine within the
specified operating range.

●

Do not continue driving with an
overheated engine. See “If your
vehicle overheats” in section 4.

Tachometer

The tachometer indicates the engine
speed in thousands of rpm (revolutions
per minute). Use it while driving to select
correct shift points and to prevent engine
lugging and over-running.
Driving when the engine is running too fast
may cause excessive engine loss and poor
fuel economy.

F3/F3R OWNER’S MANUAL

- 74 -

Remember. In most cases, the slower the
engine speed is, the fewer the fuel
is consumed.
When the ignition switch is in “START”
position, there is no malfunction even if the
engine coolant temperature gauge needle
returns to “0”.

NOTICE

Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.

Odometer and two trip meters

This meter displays the following information:

1. Odometer — shows the total distance

the vehicle has been driven.

2. Two trip meters — shows two different

distances independently driven since
the last time each trip meter was set to
zero.
You can use one trip meter (TRIP A) to
calculate the fuel consumption and the
other (TRIP B) to measure the distance
on each trip.

3. Trip meter reset knob — resets the two

trip meters to zero, and also change the
meter display.
To change the meter display,
quickly push and release the knob. The
meter displays changes in the order

F3/F3R OWNER’S MANUAL

- 75 -

from the odometer to trip meter (TRIP A),
then to trip meter (TRIP B), then back to
the odometer upon every pressing.
To reset the trip meter A to zero, display

the meter (TRIP A/ TRIP B) reading;
then, push and hold the knob until the
meter is set to zero.

(a) Brake system warning light
This light comes on in the following cases
when the ignition key is at the “ON” position.

●

The brake fluid level is low.

CAUTION

It is dangerous to continue driving
normally when the brake fluid level is
low.

Have your vehicle checked at your BYD
AUTO service station in the following cases:
●

The light does not illuminate even if the
parking brake is applied when the
ignition key is in the “ON” position.

●

The light does not illuminate even if the
ignition key is turned on with the parking
brake released.

A warning light turning on briefly during

operation does not indicate a problem.

CAUTION

If either of the following conditions
occurs, immediately park your vehicle at a
safe place and contact your BYD AUTO
service station.
●

The light does not turn off even when
the parking brake is released while
the engine is running. In this case,
the brakes may not work properly

and your stopping distance

will become longer.
Depress the brake pedal
firmly and bring the vehicle
to an immediate stop.

●

The brake system warning light
remains on together with the “ABS”
warning light.

In this case, not only the
ABS will fail but also the vehicle will
become extremely unstable during
braking.

(b) Seat belt reminder light
This light reminds the driver to buckle up the
seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light
flashes if the driver’s seat belt is not
fastened. Unless the driver fastens the belt,
the light keeps flashing.

(c) Discharge warning light
This light warns that the battery is being

F3/F3R OWNER’S MANUAL

- 79 -

discharged.
If it comes on while you are driving, there is a
problem somewhere in the charging system.
The engine ignition will continue to operate
until the battery is discharged, however. Turn
off the air conditioning, blower, radio, etc.,
and drive directly to the nearest BYD AUTO
service station.
(d) Low engine oil pressure warning light
This light warns that the engine oil pressure is
too low.
If it flickers or stays on while you are driving,
pull over to a safe place and stop the engine
immediately. Call a BYD AUTO service
station for assistance.
The light may occasionally flicker when the
engine is idling or it may illuminate briefly

after a hard stop. There is no cause for
concern if it then goes out when the engine is
accelerated slightly.
The warning light will be on if the level of oil is
low as well. This light
isn’t designed to indicate the low oil level. The
oil level must be inspected by oil dip rod.

NOTICE

Do not drive the vehicle with the
warning light on — even for one block.
It may ruin the engine.

(e) Malfunction indicator light
This light comes on when the electronic
injection system of the engine fails to work.
If it comes on, contact your BYD AUTO
service station as soon as possible.

(f) Low fuel level warning light
When the fuel is nearly empty, the
light will be on. Please fill the fuel at once.
When driving on the slope or taking a turning,
the light would usually be on
earlier because the fuel in tank will swash.

(g) “ABS” warning light
The light comes on when the ignition switch is
turned to the “ON” position. If there is no
malfunction about the ABS, the light will be
off in few seconds. Then, the light would be
on again caused by any malfunction of the
system.
When the “ABS” warning light is on (and the
brake system warning light is off), the

F3/F3R OWNER’S MANUAL

- 80 -

anti-lock brake system does
not operate, but the brake system still
operates conventionally.
When the “ABS” warning light is on (and the
brake system warning light is
off), the wheels could lock up during a
sudden brake or brake on slippery road
surfaces because the anti-lock brake system
does not operate.
If either of the following conditions occurs,
this indicates that a malfunction somewhere
in the components is monitored by the
warning light system. Contact your BYD
AUTO service station as soon as possible to
check the vehicle.

●

The light does not illuminate or become

solid on when the

ignition key is turned to the
“ON” position.

●

The light comes on while you are
driving.

A warning light turning on briefly during
operation does not indicate a problem.

CAUTION

If the “ABS” warning light remains on
together with the brake system warning
light, immediately park your vehicle at a
safe place and contact your BYD AUTO
service station.
In this case, not only the ABS will fail
but also the vehicle will become
extremely unstable during braking.

(h) Open door warning light
This light remains on until all the side door
and back door are completely closed.

(i) SRS warning light
This light will illuminate when the ignition key
is turned to the “ON” position. After about 5
seconds, the light will go off. This means that
the system of the airbag is operating
properly.
The warning light system monitors the SRS
airbag system ECU, front seat belt
pretensioner assemblies, inflators, warning
light, interconnecting wiring, and power
