When trouble arises 1 Stop the hybrid system. Set the
parking brake and shift the shift
position to P.
2 Remove the mud, snow or sand
from around the rear wheels.
3 Place wood, stones or some other
material under the rear wheels to
help provide traction.
4 Restart the hybrid system.
5 Shift the shift position to D or R and
release the parking brake. Then,
while exercising caution, depress
the accelerator pedal. ■
When it is difficult to free the vehicle
Press the switch to turn off TRAC.If the vehicle becomes stuck Carry out the following proce-
dures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Recovering procedure WARNING■
When attempting to free a stuck vehi-
cle
If you choose to push the vehicle back
and forth to free it, make sure the sur-
rounding area is clear to avoid striking
other vehicles, obje cts or people. The
vehicle may also lunge forward or lunge
back suddenly as it becomes free. Use
extreme caution. ■
When shifting the shift position
Be careful not to shift the shift position
with the accelerator pedal depressed.
This may lead to un expected rapid accel-
eration of the vehicle that may cause an
accident resulting in death or serious
injury.
NOTICE■
To avoid damaging the transmission
and other components ●
Avoid spinning the rear wheels and
depressing the accelerator pedal
more than necessary. ●
If the vehicle remains stuck even after
these procedures are performed, the
vehicle may require towing to be freed.

Vehicle specifications ■
Traction AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on
wet pavement as measured under con-
trolled conditions on specified govern-
ment test surfaces of asphalt and
concrete. A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to
this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction. ■
Temperature A, B, C
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under controlled condi-
tions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudd en tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Fede ral Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades of a tire
assume that it is prop erly inflated and not
overloaded.
Excessive speed, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.

sion, power steering, power brakes, power win-
dows, power seats, radio and heater, to the extent

WARNING■
During customization
As the hybrid system needs to be operat-
ing during customizatio n, ensure that the
vehicle is parked in a place with ade-
quate ventilation. In a closed area such as
a garage, exhaust gases including harm-
ful carbon monoxide (CO) may collect
and enter the vehicle. This may lead to
death or a serious health hazard.
