occurring. Increased exhaust gas
temperatures could damage the catalytic
converter or other vehicle components.
Drive in a moderate fashion (avoid heavy
acceleration and deceleration) and have
your vehicle immediately serviced.
It illuminates when you switch the ignition
on prior to engine start to check the bulb
and to indicate whether your vehicle is
ready for Inspection and Maintenance
(I/M) testing.
Normally, it illuminates until the engine is
cranked and automatically turns off if no
malfunctions are present. However, if after
15 seconds it flashes eight times, this
indicates that your vehicle is not ready for
Inspection and Maintenance (I/M) testing.

D (start) - Cranks the engine.
STARTING A GASOLINE
ENGINE
When you start the engine, the idle speed
increases, this helps to warm up the
engine. If the engine idle speed does not
slow down automatically, have your
vehicle checked by an authorized dealer.
Before starting the engine check the
following:
• Make sure all occupants have fastened
their safety belts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P) or neutral (N).
• Turn the ignition key to the on position.
Note: Do not touch the accelerator pedal.
1. Fully press the brake pedal.
2. Turn the key to the start position to start the engine. Release the key when
the engine starts.
Note: The engine may continue cranking
for up to 15 seconds or until it starts.
Note: If you cannot start the engine on the
first try, wait for a short period and try again.
Failure to Start
If you cannot start the engine after three
attempts, wait 10 seconds and follow this
procedure:
1. Fully press the brake pedal.
2. Fully press the accelerator pedal and hold it there.
3. Start the engine. Stopping the Engine When Your
Vehicle is Stationary
1. Shift into park (P) or neutral (N).
2. Turn the key to the off position.
3. Apply the parking brake.
Stopping the Engine When Your
Vehicle is Moving
WARNING
Switching off the engine when the
vehicle is still moving will result in a
loss of brake and steering assistance.
The steering will not lock, but higher effort
will be required. When the ignition is
switched off, some electrical circuits,
including air bags, warning lamps and
indicators may also be off. If the ignition
was turned off accidentally, you can shift
into neutral (N) and re-start the engine. 1. Put the transmission into neutral (N)
and use the brakes to bring your vehicle
to a safe stop.
2. When your vehicle has stopped, shift into park (P) or neutral (N) and switch
the ignition off.
3. Apply the parking brake.
Guarding Against Exhaust Fumes WARNING
If you smell exhaust fumes inside
your vehicle, have your vehicle
checked by your authorized dealer
immediately. Do not drive your vehicle if
you smell exhaust fumes. Carbon
monoxide is present in exhaust fumes.
Take precautions to avoid its dangerous
effects. 87
F650750 (TBC) , enUSA, Edition date: 201708, First Printing Starting and Stopping the Engine

Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, the vehicle is not ready for I/M
testing.
If the vehicle
’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving:
1. 15 minutes of steady driving on an expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle. SELECTIVE CATALYTIC
REDUCTANT SYSTEM - DIESEL
Your vehicle may have a selective catalytic
reduction system. The system helps reduce
emission levels of oxides of nitrogen from
the exhaust system. The system
automatically injects diesel exhaust fluid
into the exhaust system to enable correct
selective catalytic reduction system
function.
Note:
Selective catalytic reduction systems
are not fitted to vehicles in markets where
only high-sulfur diesel fuel is available.
Diesel Exhaust Fluid Level
In order for the system to operate correctly
you must maintain the diesel exhaust fluid
level.
A warning message appears in the
information display when the diesel
exhaust fluid level is low. If a warning
message appears, refill the diesel exhaust
fluid tank as soon as possible. See
Information Messages (page 66).
Filling the Diesel Exhaust Fluid
Tank WARNINGS
Keep diesel exhaust fluid out of
reach of children. Avoid contact with
skin, eyes or clothing. In case of
contact with your eyes, flush immediately
with water and get prompt medical
attention. In case of contact with your skin,
clean immediately with soap and water. If
you swallow any diesel exhaust fluid, drink
plenty of water, call a physician
immediately.
