overheating TOYOTA RAV4 1997 Owners Manual

78With the selector lever in 2º, the vehicle
will
start in the first gear and automatically
shift to the second gear.
With the selector lever in Lº, the trans-
mission is engaged in the first gear.
NOTICE
Be careful not to overrev the en-
gine. Watch the tachometer to
keep engine rpm from going intothe red zone. The approximatemaximum allowable speed for
each position is given below foryour reference:Two-wheel drive models
2º 130 km/h (80 mph). . . . . .
Lº 72 km/h (44 mph) . . . . .
Four-wheel drive models
215/70R16 tires 2º 121 km/h (75 mph). . . . . .
Lº 67 km/h (41 mph) . . . . .
235/60R16 tires 2º 188 km/h (73 mph). . . . . .
Lº 65 km/h (40 mph) . . . . .
Do not continue hill climbing or
hard towing for a long time in the
2º or Lº position. This may
cause severe automatic transmis-sion damage from overheating.
To prevent such damage, Dºposition should be used in hillclimbing or hard towing.
(d) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
Rº position.
NOTICE
Never shift into reverse while the vehicle is moving.
(e) Parking
1. Bring the vehicle to a complete stop.
2. Pull the parking brake lever up fully to securely apply the parking brake.
3. With the brake pedal pressed down, shift the selector lever to the Pº posi- tion.
While the vehicle is moving, never
attempt to move the selector lever
into Pº position under any circum-
stances. Serious mechanical dam-
age and loss of vehicle control mayresult. CAUTION
!
(f) Good driving practice If the transmission is repeatedly up-
shifted and downshifted between third
gear and overdrive when climbing a
gentle slope, the overdrive switch
should be turned off. Be sure to turn the switch on immediately afterward.
When towing a trailer, in order to main-
tain engine braking efficiency, do notuse overdrive.
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping. CAUTION

CAUTION!
Before driving off, make sure that the parking brake if fully released
and the parking brake reminder
light is off.
Do not leave your vehicle unat-
tended while the engine is running.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
Be careful when accelerating, up-
shifting, down shifting or braking
on a slippery surface. Sudden ac-
celeration or engine braking, could cause the vehicle to spin or skid.Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high-speed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are high-speed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-ger stopping distance, and it may
pull to one side when the brakes are
applied. Also, the parking brake
will not hold the vehicle securely.CAUTION!
Always observe the following pre-
cautions to minimize the risk of seri-
ous personal injury or damage to
your vehicle: Drive carefully when off the road. Do not take unnecessary risks by
driving in dangerous places.
Do not grip the steering wheel
spokes when driving off-road. A
bad bump could jerk the wheel and
injure your hands. Keep both
hands and especially your thumbs
on the outside of the rim.
Always cehck your brakes for ef-fectiveness immediately after driv-
ing in sand, mud, water or snow.
After driving through tall grass,
mud, rock, sand, rivers, etc., check
that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or
trapped on the underbody. Clear
off any such matter from the un-
derbody. If the vehicle is used with these materials trapped or adher-
ing to the underbody, a breakdown
or fire could occur.
Off-road driving precautions

127

Avoid jerky starts or sudden accelera- tion. If your vehicle has manual trans-
mission, prevent excessive clutch slip-
page by keeping engine rpm low and
not racing the engine. Always start out
in first gear.
Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden braking.
Backing w ith a trailer is difficult and re-
quires practice. Grip the bottom of thesteering 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 procedure is generally opposite to that when
backing without a trailer). Also, just
turn the steering wheel a little at a time,
avoiding sharp or prolonged turning. Have someone guide you when back-
ing to reduce the risk of an accident.
Remember that when making a turn, the trailer wheels will be closer than the vehicle wheels to the inside of the
turn. Therefore, compensate for this
by making a larger than normal turning
radius with your vehicle.
Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay atten-
tion to the rear from time to time to pre-
pare yourself for being passed by largetrucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed.
Steer straight ahead. If you make no
extreme correction with the steering or
brakes, the vehicle and trailer will sta- bilize.
Be careful when passing other ve- hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.
In order to maintain engine braking ef-
ficiency, do not use fifth gear (manual
transmission or overdrive (automatic transmission).
Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over30 5C [85 5F]) when going up a long or steep
grade with a trailer. If the engine
coolant termperatue gauge indicates
overheating, immediately turn off the
air conditioning (if in use), pull off the
road and stop in a safe spot. Refer to
If your vehicle overheatsº in Part 4 ofthis manual.
Always place wheel blocks under both
the vehicle and trailer wheels whenparking. Apply the parking brake firm-
ly. Put the transmission in Pº (auto-
matic) or in first or reverse (manual).
Avoid parking on a slope with a trailer, but if it cannot be avoided, do so onlyafter performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, release your brakes slowly until the blocks absorb the load.
4. Apply the parking brake frimly.
5. Shift into first or reverse (manual) or Pº (automatic) and turn off the engine.

Avoid continuous speeding up and
slowing down. Stop-and-go driving
wastes fuel.
Avoid unnecessary stopping and braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or take
advantage of through streets to avoid
traffic lights. Keep a proper distance
from other vehicles to avoid suddenbraking. This will also reduce wear onyour brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the clutch
or brake pedal. This causes needless
wear, overheating and poor fuel econ-
omy.
Maintain a moderate speed on highways. The faster you drive, the
greater the fuel consumption. By re-
ducing your speed, you will cut down
on fuel consumption.
Keep the front wheels in proper alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on the
engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps prevent corrosion.
Keep your vehicle tuned-up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc.
all lower engine performance and con-
tribute to poor fuel economy. For lon-
ger life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive undersevere conditions, see that your ve-
hicle receives more frequent mainte-
nance (For scheduled maintenance in-
formation, please refer to the separate
Owner 's Manual Supplement/Main-
tenance Scheduleº).
CAUTION!
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is run-
ning.

If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a
loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure 0
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in Pº
(automatic) or neutral (manual) and
apply the parking brake. Turn off the
air conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running and make sure the electric
cooling fan is operating. If it is not, turn
the ignition off.
To help avoid personal injury, keep
the hood closed until there is no steam. Escaping steam or coolant is
a sign of very high pressure. CAUTION
! 3. Look for obvious coolant leaks from
the radiator, hoses, and under the ve-
hicle. However, note that water drain- ing from the air conditioning is normal if it has been used.
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts. CAUTION
!
4. If the coolant is leaking, stop the en- gine immediately. Call a Toyota dealer
for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine is running. Fill it about half full.
Do not attempt to remove the radia-
tor cap when the engine and radiator
are hot. Serious injury could result
from scalding hot fluid and steam
blown out under pressure. CAUTION
! 6. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If
necessary, bring it up to half full again.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at your
Toyota dealer.
