WARNING
■Handling of tires and the suspension 
Using tires with any kind of problem or modifying the suspensio n will affect 
the driving assist systems, and may cause a system to malfuncti on. 
■ Trailer Sway Control precaution 
The Trailer Sway Control system is not able to reduce trailer s way in all situ- 
ations.  
Depending  on  many  factors  such  as  the  conditions  of  the  vehicle ,  trailer, 
road surface and driving environm ent, the Trailer Sway Control system may 
not be effective. Refer to your trailer owner’s manual for info rmation on how 
to tow your trailer properly. 
■ If trailer sway occurs 
Observe the following precautions.  
Failing to do so may cause death or serious injury. 
● Firmly grip the steering wheel. Steer straight ahead.  
Do not try to control trailer sway by turning the steering whee l. 
● Begin  releasing  the  accelerator  pedal  immediately  but  very  gradually  to 
reduce speed.  
Do not increase speed. Do not apply vehicle brakes. 
If you make no extreme correction with the steering or brakes,  your vehicle 
and trailer should stabilize. ( P. 301)

◆Checking tire inflation pressure 
Make  sure  to  check  the  tire  inflation  pressure  frequently.  Impr oper 
tire inflation pressure can cause poor fuel economy. 
Also, as snow tires can cause large amounts of friction, their  use on 
dry roads can lead to poor fuel economy. Use tires that are app ro- 
priate for the season.
◆Luggage 
Carrying heavy luggage will lead to poor fuel economy. Avoid ca rry- 
ing unnecessary luggage. Installing a large roof rack will also  cause 
poor fuel economy.
◆Warming up before driving 
Since  the  gasoline  engine  starts  up  and  cuts  out  automatically 
when  cold,  warming  up  the  engine  is  unnecessary.  Moreover,  fre- 
quently  driving  short  distances  will  cause  the  engine  to  repeat edly 
warm up, which can lead to excess fuel consumption.
