■ If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there may
be a problem with the shift lock system (a system to prevent accidental oper-
ation of the shift lever). Have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer immediately.
The following steps may be used as an emergency measure to ensure that
the shift lever can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the engine switch to the “LOCK” position (vehicles without a smart
entry & start system) or ACCESSORY mode (vehicles with a smart entry &
start system).
Depress the brake pedal.
Pry the cover up with a flathead screw-
driver or equivalent tool.
To prevent damage to the cover, wrap
the tip of the screwdriver with a rag.

■ When driving vehicle in country with different speed unit
Since RSA recognizes signs based on the set unit of the meter, it is neces-
sary to change the set unit of the meter. Adjust the set unit of the meter to the
speed unit of signs in the current location. ( P. 671)
■ Turning the system on/off
■ Speed limit sign display
If the engine switch was last turned off while a speed limit sign was displayed
on the multi-information display, the same sign displays again when the
engine switch is turned to “ON” position (vehicles without smart entry & start
system) or IGNITION ON mode (vehicles with smart entry & start system).
■ When “Check RSA system.” is displayed on the multi-information dis-
play
The system may be malfunctioning. Have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer
immediately.
■ Customization
The settings for warning display, warning buzzer*, speeding warning thresh-
old, etc., can be changed. (Customizable feature: P. 671)
*: If a speed limit with supplemental mark is exceeded, the warning buzzer
does not operate.
Select on the settings display
( P. 118)
Press the enter/set switch on the meter
control switches.
WARNING
■ Before using the RSA
Do not rely solely upon the RSA system. RSA is a system which supports
the driver by providing information, but it is not a replacement for a driver’s
own vision and awareness. Drive safely by always paying careful attention
to the traffic rules.
Inappropriate or negligent driving could lead to an unexpected accident.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the specified size and brand, and that chains
match the size of the tires.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
●Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.
