Driving
WARNING
• Conditions under which the system may not operate properly:
P.172
●Do not attempt to test the operation of
the pre-collision system yourself.
Depending on the objects used for
testing (dummies, cardboard objects
imitating detectable objects, etc.), the
system may not operate properly, pos-
sibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking func-
tion is operating, a large amount of
braking force will be applied.
●If the vehicle is stopped by the opera-
tion of the pre-collision braking func-
tion, the pre-collision braking function
operation will be canceled after
approximately 2 seco nds. Depress the
brake pedal as necessary.
●The pre-collision braking function may
not operate if certain operations are
performed by the driver. If the acceler-
ator pedal is being depressed strongly
or the steering wheel is being turned,
the system may determine that the
driver is taking evasive action and pos-
sibly prevent the pre-collision braking
function from operating.
●In some situations, while the pre-colli-
sion braking function is operating,
operation of the function may be
canceled if the accelerator pedal is
depressed strongly or the steering
wheel is turned and the system deter-
mines that the driver is taking evasive
action.
●If the brake pedal is being depressed,
the system may determine that the
driver is taking evasive action and pos-
sibly delay the operation timing of the
pre-collision braking function.
■Emergency steering assist
●As emergency steering assist opera-
tion will be canceled when the system
determines that lane departure pre-
vention function ha s been completed.
●Emergency steering assist may not
operate or may be ca nceled in the fol-
lowing cases as the system may deter-
mine the driver is taking actions.
• If the accelerator pedal is being depressed strongly, the steering wheel
is being operated sharply, the brake
pedal is being depressed or the turn
signal lever is being operated. In this
case, the system may determine that
the driver is taking evasive action and
the emergency steeri ng assist may not
operate.
• In some situations, while the emer- gency steering assist is operating,
operation of the function may be
canceled if the ac celerator pedal is
depressed strongly, the steering wheel
is operated sharply or the brake pedal
is being depressed and the system
determines that the driver is taking
evasive action.
• When the emergency steering assist is operating, if the steering wheel is held
firmly or is operated in the opposite
direction to that which the system is
generating torque, the function may be
canceled.
■When to disable the pre-collision sys-
tem
In the following situations, disable the
system, as it may not operate properly,
possibly leading to an accident resulting
in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another
vehicle
●When transporting the vehicle via
truck, boat, train or similar means of
transportation

3467-2. Steps to take in an emergency
4Remove the guide pin and loosely
tighten the wheel bolt as in step 3.
5 Lower the vehicle.
6 Firmly tighten each wheel bolt in
the order shown in the illustration
two or three times.
Tightening torque:
103 ft•lbf (140 N•m, 14.3 kgf•m)
7Stow the flat tire, tire jack and all
tools.
■The compact spare tire
●The compact spare tire is identified by the
label “TEMPORARY USE ONLY” on the tire sidewall.
●Use the compact spare tire temporarily,
and only in an emergency.
●Make sure to check the tire inflation pres-
sure of the compact spare tire. (P.372)
■When using the compact spare tire
As the compact spare tire is not equipped
with a tire pressure warning valve and trans-
mitter, low inflation pressure of the spare
tire will not be indicated by the tire pressure
warning system. Also, if you replace the
compact spare tire after the tire pressure
warning light comes on, the light remains
on.
■When the compact spare tire is
equipped
The vehicle becomes lower when driving
with the compact spare tire compared to
when driving with standard tires.
■If you have a flat rear tire on a road cov-
ered with snow or ice (vehicles with
front and rear tires of the same size)
Install the compact spare tire on one of the
front wheels of the vehicle. Perform the fol-
lowing steps and fit tire chains to the rear
tires:
1 Replace a front tire with the compact
spare tire.
2 Replace the flat rear tire with the tire
removed from the front of the vehicle.
3 Fit tire chains to the rear tires.
WARNING
■Installing the compact spare tire
Failure to follow these precautions could
cause the wheel bolts to loosen and the
tire to fall off, result ing in death or serious
injury.
