Lift and Support Points
Lift and Safety Stands
ffi When heaw rear components such as suspension, Iuel tank, spare tire and tailgate are to b€ lemoved, place
!iiii-'rn"t r""igtrt in the trunk before hoisting. When substantial weight is removed flom the lear ot the vehicle, the
center of gravity may change and can cause the vehicle to tip fotward on the hoist'
NOTE: Since each tire/wheel assembly weighs approximately 30 lbs (14 kg), placing the front wheels in the cargo area can
assist with weight distribution.
1. Place the lift blocks as shown.
2. Raise the hoist a few inches (centimeters), and rock the vehicle to be sure it is firmly supported.
3. Raise the hoist to full height, and inspect the lift points for solid support'
NOTE: Use the same suppon points to support the vehicle on safety stands'

Block the rear wheels when raising the front of thevehicle; block the front wheels when raising the rearof the vehicle.
Place the blocks behind and ahead of the wheels,
Raise the vehicle high enough to insert the safetystanos.
Adjust and place the safety stands so the vehiclewill be approximately level, then lower the vehicleonto them.

Towing
lf the vehicle needs to be towed, call a professional
towing service. Never tow the vehicle behind another
vehjcle with just a rope or chain. lt is very dangerous.
Emergency Towing
There are three popular methods of towing a vehicle.
Flat-bed Equipment - The operator loads the vehicle on
the back of a truck. This is the best way of transporting the
vehicle.
Wheel Lift Equipment - The tow truck uses tlvo pivoting
arms that go under the tires lfront or rear) and lifts them
off the ground. The other two tires remain on the
ground. The vehicle's suspension and body can be
seriously damaged if this method of towing is attempted.
Sling-type Equipment - The tow truck uses metal cables
with hooks on the ends. These hooks go around parts of
the frame or suspension and the cables lift that end of
the vehicle off the ground. The vehicle's suspension and
body can be seriously damaged if thjs method of towing
is attempted. This methed of towing the CR-V is
unaccePtable.
The onlv recommended way of towing the CR-V is on a
flat-bed truck. Two wheel drive CR-V's may also be
towed with all four wheels on the ground.
Towing the four-wheel dlive CR-v with only two
wheels on the ground will damage parts of the 4wD
system. It this vehicle is damaged, it should be towed
on a flat-bed truck ol trailel.
It the 2 wheel drive CR-v is towed wiih all tour wheels
on the ground, do the following:
Manual Transmission
. Release the parking brake.
. Shift the transmission in Neutral
Automatic Transmission
. Release the parking brake.
. Sta rt the engine.
. Shift to lD.l position. then E position.
. Turn off the engine.
lmproper towing preparation will damage the
transmission. Follow the above procedure exactly. lf
you cannot shift the transmission or start the engine,
the vehicle must be transported on a flat-bed truck.
lf the vchicle is towed with four wheels on the ground,
il is best to tow the vehicle no larther than 50 miles (80
km), and keep the speed below 35 mph {55 km/h).
Trying to lift or tow the vehicle by ihe bumpers will
cause serious damage. The bumpers ale not dosigned
to support the vehicle's weight.

Precautions for Real-time 4WD (Four-wheel Drivel
Under normal conditions, the vehicle is in 2WD (front-wheel drive). However, the system will instantly transmit
appropriate driving force to the rear wheels {depending on the driving force of the front wheels and the road conditons)
The Real-time 4WD-Dual Pump System does not have a manual switch to disable the 4WD system. Whenever service
work requires spinning the front or rear wheels with the engine, always lift up and support the vehicle so all lour wheels
are off the ground (see page 1- 19).

22. Remove the radiator caP.
!@ use care when removing the radiatol
cap to avoid scalding by hot coolani or steam.
23. Raise the hoist to full height
24. Remove the front tires/wheels.
25. Remove the guard bar and splash shield.

Loosen the drain plug in the radiator. Drain the
engine coolant (see page 10-51.
Drain the transmission oil or fluid. Reinstall the drain
plug using a new washer lsee section 13 (M/T) or sec-
tion 14 (ly'T)].
Drain the engine oil. Reinstall the drain bolt using a

@ Make sure tifts, iacks, and satety stands
are placed properly (see section 1).
L Raise the front of the vehicle, and support it with
safety stands (see section 1).
2. Set the parking brake, and block both rear wheels
securely.
3. Shift to neutral oosition.
4. Make a reference mark across the DroDeller shaft
and the transfer assembly flanges,

1.lf the measurement is out of specification, remove
the transfer assembly and adjust transfer gear back-
lash (see page 13-44 thru '13-61).
Check the transfer oil seal for damage and fluid
teaKs.
lf oil seal replacement is required, remove the trans-
fer assembly, replace the oil seal, and adjust the
total starting torque (see page 13-44 thru 13-61).
NOTE: Do not replace the oil seal when the transfer
assembly is installed on the transmission.
