Before driving
SIENNA_OM_OM45483U_(U)
■
Notes for the unlocking function
●Gripping the front door handle when wearing a glove may not unlock or
lock the door.
● A sudden approach to the effective range or door handle operation may
prevent the doors from being unlocked. In this case, return the door han-
dle to the original position and check that the doors have unlocked before
pulling the door handle.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after one of the front door handles is gripped
or one of sliding door handles is pulled.
■ When the vehicle is not dr iven for extended periods
● To prevent theft of the vehicle, do not leave the electronic key within 6 ft.
(2 m) of the vehicle.
● The smart key system can be deactivated in advance. ( P. 828)
■ To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention may not
operate.)
■ If the smart key system does not operate properly
● Locking and unlocking the doors: Use the mechanical key. ( P. 781)
● Starting the engine ( P. 782)

2-1. Driving procedures

When driving
SIENNA_OM_OM45483U_(U)
CAUTION
■
When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
● Sudden changes in engine speed, such as engine braking caused by up-
shifting and down-shifting, may cause the vehicle to skid, resulting in an
accident.
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
■ When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
Shifting the shift lever to a gear other than P or N may lead to unexpected
rapid acceleration of the vehicle that may cause an accident and result in
death or serious injury.
■ If you hear a squealing or scrapin g noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Toyota dealer as soon
as possible.
Rotor damage can result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.

NOTICE
■
To prevent battery discharge
●Do not leave the “ENGINE START STOP” switch in ACCESSORY or IGNI-
TION ON mode for long periods of time without the engine running.
● If the indicator on the “ENGINE START STOP” switch is illuminated, the
“ENGINE START STOP” switch is not off. When exiting the vehicle,
always check that the “ENGINE START STOP” switch is off.
● Do not stop the engine when the shift lever is in a position other than P. If
the engine is stopped in another shift lever position, the “ENGINE START
STOP” switch will not be turned off but instead be turned to ACCESSORY
mode. If the vehicle is left in ACCESSORY mode, battery discharge may
occur.
■ When starting the engine
●Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.
■ Symptoms indicating a malfunction with the “ENGINE START STOP”
switch
If the “ENGINE START STOP” seems to be operating somewhat differently
than usual, such as the switch sticking slightly, there may be a malfunction.
Contact your Toyota dealer immediately.
