RC F_U WARNING ■
When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.●
Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to chokin g or other serious injuries that could result
in death. If this occurs and the buckle can not be unfastened, scissors should be used
to cut the belt. ●
Ensure that the belt and plate are securely locked and the seat belt is not twisted.●
Shake the child restraint syst em left and right, and forward and backward to ensure
that it has been securely installed. ●
After securing a child restraint system, ne ver adjust the seat.●
When a booster seat is installed, always en sure that the shoulder belt is positioned
across the center of the child’s shoulder. The belt should be kept away from the child’s
neck, but not so that it coul d fall off the child’s shoulder.●
Follow all installation instructions provided by the child restraint system manufacturer.■
When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten on ly. This could cause injury or discomfort to
the child. (  P. 36)■
Do not use a seat belt extender
If a seat belt extender is used when insta lling a child restraint system, the seat belt will
not securely hold the child restraint system , which could cause death or serious injury
to the child or other passengers in the event of sudden braking, sudden swerving or an
accident.

Welcome illumination of the analog speedometer●
When the driver’s door is opened, th e analog speedometer will illuminate.
Then, when the driver’s door is closed, the analog spee dometer will illuminate and go
off (pulsate) 3 times. ●
In the following situations, the analog sp eedometer will not pulsate even though the
driver’s door is opened and closed:
• Within 60 seconds after the an alog meter pulsation completes
• Within 60 seconds of turning the engine switch off ■
Variable red zone
■
Eco driving meter ●
The number of blue segments displayed on the eco driving meter decreases/increases
depending on the vehicle acceleration. Use th is meter as a guideline when you wish to
drive in an eco-friendly manner that reduces fuel consumption.
However, on a downward grade where the ve hicle can accelerate without the acceler-
ator pedal being depressed, the eco driv ing meter may not display the eco-driving
state correctly. ●
When the shift lever is moved to P, N or R, the segments will turn gray and the eco driv-
ing meter will not operate.To help protect the engine, the engine speed is
controlled by starting the red zone of the
tachometer at different engine speeds ranging
from 3700 rpm to 7300 rpm depending on the
engine coolant temperature.
Before driving under extremely high load condi-
tions, make sure to su fficiently warm up the
engine.
