When driving
■
Daytime running light system (if equipped)
●To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the engine is started and
the parking brake is released. Daytime running lights are not designed for
use at night.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help
improve fuel economy.
■ Light reminder buzzer
A buzzer sounds when the engine switch is turned to the “LOCK” or “ACC”
position and the driver’s door is opened while the lights are turned on.
■ Battery-saving function (vehicles with an alarm system or daytime run-
ning light system)
In all following conditions, the headlights and the other remaining lights will
go off automatically after 20 minutes in order to prevent the vehicle battery
from being discharged:
●The engine switch is in the “LOCK” position.
● The headlights and/or tail lights are on.
This function will be canceled in any of the following situations:
● When the engine switch is turned to the “ON” position.
● When the light switch is operated.
● When the door is opened or closed.
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not run-
ning.

164 2-4. Using other driving systems
■Turning off both TRAC and VSC systems

tems off, press and hold the but-
ton for more than 3 seconds
while the vehicle is stopped.

■ Sounds and vibrations caused by the ABS, brake assist, VSC and
TRAC
● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■ Reactivation of the TRAC/VSC systems after turning off the engine
Turning off the engine after turning off the TRAC/VSC systems will automati-
cally reactivate them.

When driving
●
Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway . Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the stee ring or brakes, your vehicle and
trailer will stabilize.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not use the transmission in
D (vehicles with an automatic transmission) or 5 (vehicles with a
manual transmission).
● Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the high engine coolant temper-
ature warning light flashes or co mes on overheating, immediately
turn off the air conditioning (if in use), pull your vehicle off the road
and stop in a safe place. ( P. 334)

If the fluid level is at or below the
“LOWER LEVEL” line, add dis-
tilled water.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear out or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious proble\
