FOR VEHICLES FITTED WITH CNG FUEL SYSTEM
INTRODUCTION TO CNG:
CNG (Compressed Natural Gas) is princi-
pally constituted by methane. CNG is
considered as clean burning fuel. Due to
low density of CNG, it is compressed at a
pressure of around 200 bars to enhance the
vehicle on-board storage capacity.
CAUTION
In case of any symptom of CNG leakage
or releasing noise or any external
damage to CNG piping or during
accident, do not panic.
•Stop the vehicle and switch off the
engine, roll down the windows and
open all the doors
•Ensure to close manual shut off valve.
•Contact Maruti Suzuki authorized
workshop immediatly for further
assistance.
SAFETY PRECAUTIONS (Do’s): SAFETY PRECAUTIONS (Don’ts):
1. If any service or body repair is to be
carried out, turn the manual shut off
valve on CNG cylinder valve to close
position prior to commencement of the
repair work.
2. Get the CNG cylinder checked every
five (5) years from the date of last
testing / retesting of cylinder by
government authorized CNG cylinder
testing agency.
3. If the vehicle does not changeover to
CNG in AUTO MODE, then have your
vehicle checked by Maruti Suzuki
authorized workshop at the earliest.
4. Switch "OFF" engine while fuel filling
(CNG/Petrol).
5. After refueling CNG or Petrol, ensure
that the fuel filler lid is closed. (Other-
wise vehicle cannot be started)
6. In AUTO MODE, It is programmed to
start the vehicle in petrol and auto-
matically shift to CNG based on the
engine temperature etc. Do not press
the accelerator pedal to change from
petrol to CNG.
1. Do not change/modify the configuration,
settings or the components from CNG
system.
2. The CNG cylinder should not be
repaired under any circumstances, in
case of any problem, consult with Maruti
Suzuki authorized workshop.
3. Do not adjust setting of CNG system.
4. Never install LPG or any other gas
cylinder in place of CNG cylinder.
5. Avoid carrying inflammable material near
the CNG cylinder.
6. Do not fill any other type of gas other
than CNG.
7. Do not press the accelerator pedal to
change from petrol to CNG MODE.

FUEL MODES
NOTE:
• Do not press the accelerator pedal to
changover from petrol to CNG mode.
• With ignition switch "ON" and engine not
running, blinking of CNG malfunction
warning lamp indicates that fuel lid is
open. Vehicle will not start in this
condition.
There are three fuel modes in the vehicle
(Petrol, Auto and Forced CNG) which are
selectable by pressing the selector switch
(1) located on the right side of the steering
wheel on the dashboard.
PETROL MODE
In this mode vehicle starts in petrol and
continue running in petrol mode. In this
mode, petrol indicator is continuously dis-
played and CNG indicator will remain “OFF”.
Make sure that the parking brake is
applied fully and the transmission is
in Neutral before attempting to start
the engine.
• Stop turning the starter immediately
after the engine has started or the
starter system can be damaged.
• Do not crank the engine for more
than 15 seconds at a time. If the
engine doesn’t start on the first try,
wait about 15 seconds before trying
again.
CAUTION

wWARNING
SELECTOR SWITCH POSITION AUTO MODE
In this mode engine starts in petrol mode
and then automatically changes to CNG
mode after reaching programmed warming
up condition. With ignition switch ON and
vehicle started in “AUTO MODE”, CNG
indicator blinks on the display and PETROL
indicator is displayed. After changeover to
CNG, CNG indicator will be displayed and
Petrol indicator will switch OFF
automatically.
NOTE:
It is always recommended to start the
vehicle in AUTO MODE or PETROL MODE
to enhance the engine life.

FOR VEHICLES FITTED WITH CNG FUEL SYSTEM
FORCED CNG MODE
This is emergency mode and may be used
in cases where there is no petrol in petrol
tank. In this mode vehicle starts in CNG
mode and continues running in CNG mode.
With ignition "ON" and engine not running,
press and hold the changeover switch till
only CNG indicator is displayed. In this
mode, CNG indicator is displayed and Petrol
indicator remains "OFF".
NOTE:
It is recommended to keep sufficient amount
of petrol in the petrol tank.
CNG LEVEL GAUGE
When the ignition switch is in the “ON”
position, this gauge gives an approximate
indication of the quantity of CNG in the
CNG cylinder. “F” stands for full and “E”
stands for empty.
If the indicator gets off the graduation of
“E”(not character “E”) refill the CNG cylinder
as soon as possible.
The mark (1) indicates that the fuel filler lid
is located on the left side of the vehicle.
AUTOMATIC CHANGEOVER FROM
CNG MODE TO PETROL MODE
If CNG is finished while the engine is
running, vehicle will automatically change
over from CNG mode to Petrol mode &
CNG malfunction warning lamp will start
blinking. Petrol indicator will glow
continuously and CNG indicator will switch
OFF automatically.
To acknowledge this information, press the
changeover switch once. The CNG
malfunction warning lamp will stop blinking
after the changeover switch is pressed and
Petrol indicator will glow continuously.
However the CNG malfunction indicator lamp
will continue to blink after every subsequent
Ignition ON - Ignition OFF condition until the
vehicle is refilled with CNG.
NOTE:
• It is recommended to keep sufficient
amount of petrol in the petrol tank to
prevent engine stalling during automatic
changeover from CNG mode to Petrol
mode.
• In case the CNG malfunction warning
lamp does not stop blinking after
pressing the changeover switch, take the
vehicle to the nearest MARUTI SUZUKI
dealer.

CNG filler valve (1) can be uncovered by
pulling out the filler valve cover (2) and it
can be covered by simply pushing it back.
Filling automatically gets cut off when the
cylinder pressure becomes equal to
dispenser pressure. After CNG filling, ensure
that the filler valve cover (2) and fuel filler
lid (3) is closed.
NOTE:
• If the Fuel filler lid (3) is kept open, you
will not be able to start the vehicle.
• Engine will stop if the fuel filler lid (3)
is opened in vehicle stationary condition.
