Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
n Pre-winter preparations
lUse fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
l Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
l 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 same size and brand, and that chains
match the size of the tires.
nBefore driving the vehicle
Perform the following according to the driving conditions.
lDo not try to forcibly open a window, scrape an outside rear
view mirror surface or move a wiper or outside rear view mir-
ror that is frozen. Pour warm water over the frozen area to

Regulations on the use of snow chainsl Regulations regarding the use of tire chains vary according to loca-
tion and type of road. Always check local regu lations before install-
ing chains.
l Use SAE Class “S” type radial tire chains, with the exception of
radial cable chains or V-bar type chains.
• Install the chains on the front tires.
• Refer to the explanation that comes with the tire chains for
installation instructions.
l Retighten the chains after drivi ng 1/4 - 1/2 mile (0.5 - 1.0 km).
nSnow chain installation
Observe the following precautions when installing and removing chains.
lInstall and remove tire chains in a safe location.
l Install tire chains on the front tires only. Do not install tire chains on the
rear tires.
l Install the tire chains on front tires as tightly as possible.
l Install tire chains following the instructions provided in the accompanying
instructions.
l If wheel ornaments are used, they will be scratched by the chain band,
so remove the ornaments before putting on the chains. ( →P. 332)
n When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed suit-
able to road conditions.
n When parking the vehicle
Park the vehicle and move the shift lever to P (automatic trans-
mission) or to 1 or R (manual transmission) without setting the
parking brake. The parking brak e may freeze up, preventing it
from being released. If necessary , block the wheels to prevent
inadvertent sliding or creeping.

Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
lUse tires of the size specified for your vehicle.
l Maintain the recommended level of air pressure.
l Do not drive in excess of 75 mph (120 km/h) regardless of the type of
snow tires being used.
l Snow tires should be installed on all wheels.
n Driving with snow chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
lDo not drive in excess of the speed limit specified for the tire chains being
used or 30 mph (50 km/h), whichever is lower.
l Avoid driving on bumpy road surfaces or over potholes.
l Avoid sudden turns and braking.
l Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
nRepairing or replacing snow tires
Request repairs of and obtain replacement snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
n Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

Before towing
Check that the following conditions are met:
lEnsure that your vehicle’s tires are properly inflated. ( →P. 365)
l Trailer tires should be inflated according to the trailer manufacturer’s rec-
ommendation.
l All trailer lights work to be legal.
l Confirm all lights work each time you connect them.
l The trailer ball is set up at the proper height for the coupler on the t\
railer.
l Check that your vehicle remains level when a loaded or unloaded trailer
is hitched. Do not drive if the vehicle is not level, and check for improper
tongue load, overloading, worn suspension, or other possible causes.
l Make sure the trailer cargo is securely loaded.
l Check that your rear view mirrors c onform to any federal, state/provincial
or local regulations. If they do not, inst all rear view mirrors appropriate for
towing purposes.
n Break-in schedule
lToyota recommends that you do not use a new vehicle or a vehicle with
any new power train components (engine, transmission, differential,
wheel bearings, etc.) to tow a trailer for the first 500 miles (800 km) of
driving.
n Maintenance
lIf you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. (See “Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.)
l Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km).

178 2-5. Driving information
lReversing with a trailer attached is difficult and requires practice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the right to
move the trailer to the right. (This is generally opposite to reversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to reduce the risk of an acci-
dent.
l As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least o ne vehicle and trailer length.
l Avoid sudden braking as you may skid, resulting in jackknifing and
loss of control. This is especiall y true on wet or slippery surfaces.
l Avoid jerky starts or sudden acceleration. Vehicles with a manual
transmission, prevent excessive cl utch slippage by keeping engine
rpm low and not racing the engine. Always start out in first gear.
l Avoid jerky steering and sharp turns, and slow down before mak-
ing a turn.
l Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a larger than normal turning radius.
l Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway . Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the stee ring or brakes, your vehicle and
trailer will stabilize.
l Take care when passing other v ehicles. Passing requires consider-
able distance. After passing a vehi cle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.

When driving
l
In order to maintain engine braking efficiency, do not use the trans-
mission in D (automatic transmiss ion) or 5 (manual transmission).
l Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immedi ately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
( → P. 349)
l Always place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking brake firmly, and put the
transmission in P (automatic transmission) or in 1 or R (manual
transmission). Avoid parking on a slope, but if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle and
trailer wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into 1 or R (manual transmission) or P (automatic trans-
mission) and turn off the engine.
l When restarting after parking on a slope:
With the transmission in P (automatic transmission) or the
clutch pedal (manual transmission) depressed, start the
engine. On vehicles with an au tomatic transmission, be sure
to keep the brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake (also brake pedal on vehicles with
an automatic transmission), and slowly pull or back away from
the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
