Lane-keep Assist System
(LAS)
*
▼Lane-keep Assist System (LAS)
The LAS provides steering assistance to
help the driver stay within the vehicle lane
if the vehicle might be deviating.
The forward sensing camera (FSC) detects
the white lines (ye
llow lines) of the
vehicle lane in which the vehicle is
traveling and if the system determines that
the vehicle may deviate from its lane, it
operates the electric power steering to
assist the driver’s steering operation. The
system also alerts the driver by displaying
an alert on the multi-information display
and the active driving display
*. Use the
system when you drive the vehicle on
roads with white (yellow) lines such as
expressways and highways.
1. Forward sensing camera (FSC)
WA R N I N G
Do not rely completely on the LAS:
 The LAS is not an automated driving
system. In addition, the system is not
designed to compensate for a driver’s
lack of caution, and over-reliance on the
system could lead to an accident.

Overheating
▼Overheating
If the engine coolant temperature gauge
indicates overheating and the high engine
coolant temperature
warning indication is
displayed, the vehicle loses power or you
hear a loud knocking or pinging noise, the
engine is probably too hot.
WA R N I N G
Pull over to a safe location, then switch
the ignition off and make sure the fan is
not running before attempting to work
near the cooling fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if the
engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and radiator
are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot out
under pressure and cause serious injury.
Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the engine coolant temperature gauge
indicates overheating and the high engine
coolant temperature warning indication is
displayed:

1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic
transmission in park (P), a manual
transmission in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is escaping from the engine
compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.

If neither coolant nor steam is
escaping:
Open the hood and idle the engine
until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an Authorized Mazda
Dealer.

2. Turn off the engine and wait 5 minutesfor the oil to drain back into the oil
pan.
3. Inspect the engine oil level (page 6-16). If it's low, add the appropriate
amount of engine oil while being
careful not to overfill.
CAUTION
Do not run the engine if the oil level is
low. Otherwise, it could result in
extensive engine damage.
4. Start the engine and check the warning light.

If the light remains illuminated even
though the oil level is normal or after
adding oil, stop the engine immediately
and have your vehicle towed to an
Authorized Mazda Dealer.
▼ High Engine Coolant Temperature
Warning Indication

has increased excessively.
“Elevated Engine Coolant Temp. Drive
Slowly” displayed
Drive slowly to redu
ce engine load until
you can find a safe place to stop the
vehicle and wait for the engine to cool
down.
“Excessive Engine Coolant Temp. Stop
the Vehicle in a Safe Location”
displayed
This indicates the possibility of
overheating. Park the vehicle in a safe
place immediately and stop the engine.
Refer to Overheati ng on page 7-21.
CAUTION
Do not drive the vehicle with the high
engine coolant temperature warning light
illuminated. Otherwise, it could result in
damage to the engine.
▼Power Steering Malfunction
Indication/Indicator Light
The message is displayed if the electric
power steering has a malfunction.
If the message is displayed, stop the
vehicle in a safe place and do not operate
the steering wheel. Contact an Authorized
Mazda Dealer if the message is displayed
continuously.
