Q Reverse warning buzzer (6-speed transmission)
A buzzer will sound to alert the driver if the shift lever is shifted to the R posi-
tion.
Q Operation of iMT
O When the clutch pedal is depressed and the shift lever is moved to a posi-
tion, iMT controls the engine speed to be optimal for changing the shift posi-
tion. However, iMT stops operating before the shift position is changed if the
clutch pedal is not released for a while, and the engine speed cannot be
controlled. To operate iMT again, depress the clutch pedal and operate the
shift lever.
O The engine speed may be increased when the clutch pedal is depressed,
however, this does not indicate a malfunction.
Q When iMT does not operate
In the following situations, iMT may not operate. However, this does not indi-
cate a malfunction.
O The shift lever is not operated for a long time after the clutch pedal is
depressed.
O The vehicle moves for a while after the shift lever is shifted to N and the
clutch pedal is released, and then the clutch pedal is depressed and the
shift lever is moved to a position.
O The clutch pedal is not completely released and depressed again.
O The clutch pedal is not fully depressed.
Q If the warning message for iMT is shown on the multi-information dis-
play
iMT may be malfunctioning and the function is disabled. Have the vehicle
inspected at any authorized Toyota reta iler or Toyota authorized repairer, or
any reliable repairer as soon as possible.

2524-3. Operating the lights and wipers
HILUX_OM_OM0K513E_(EE)
This system allows the headlights and front position lights to be turned
on for 30 seconds when the engine switch is turned to the “LOCK”
position (vehicles without smart entry & start system) or off (vehicles
with smart entry & start system).
Pull the lever toward you and
release it with the light switch is in

engine switch to the “LOCK” posi-
tion (vehicles without smart entry
& start system) or off (vehicles
with smart entry & start system).
Pull the lever toward you and
release it again to turn off the
lights.
Q Daytime running light system (if equipped)
To make your vehicle more visible to other drivers during daytime driving, the
daytime running lights turn on automatically whenever the engine is started
and the parking brake is released with the headlight switch in . (Illuminate
brighter than the front position lights.) The daytime running light system is not
designed for use at night.
Q Headlight control sensor (if equipped)
Extended Headlight Lighting system (if equipped)
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

When the engine is stopped by the Stop & Start system when the
vehicle is on an incline, when the brake pedal is released, brake force
is temporarily maintained to prevent the vehicle from rolling back-
wards before the engine is restarted and drive force is generated.
When drive force is generated, the maintained brake force is automat-
ically canceled.
O This function operates on flat surfaces as well as steep inclines.
O Sound may be generated from the brake system, but this does not
indicate a malfunction.
O Brake pedal response may change and vibration may occur, but
this does not indicate a malfunction.
Q Points for use
O If the engine switch is pressed when the engine is stopped by the Stop &
Start system, the engine will not be able to be restarted by the automatic
engine start function. In this case, restart the engine using the normal
engine starting procedure. ( P. 220, 223)
O When the engine is being restarted by the Stop & Start system, the power
outlets may be temporarily unusable, but this does not indicate a malfunc-
tion.
O Installation and removal of electrical components and wireless devices may
affect the Stop & Start system. Contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer for details.
O When stopping the vehicle for a longer period of time, turn the engine switch
