NOTE: If you are going to remove heavy com
ponents
such as suspension or the fuel tank from the rear of the
vehicle, first support the front of the vehicle with tall
safety stands. When substantial weight is removed
from the rear of the vehicle, the center of gravity can
change, causing the vehicle to tip forward on the lift.
1. Position the lift blocks (A) under the vehicle’s front support points (B) and rear support points (C).
2. Raise the lift a few inches, and rock the vehicle gently to be sure it is firmly supported.
3. Raise the lift to its full height, and inspect the vehicle support points for solid contact with the lift
blocks.
To support the vehicle on safety stands, use the same
support points as for a vehicle lift. Always use safety
stands when working on or under any vehicle that is
supported only by a jack. 1. When lifting the front of the vehicle, set the parking
brake. When lifting the rear of the vehicle, put the
shift lever in reverse for manual transmission, or in
P for automatic transmission.
2. Block the wheels that are not being lifted.
3. Position the floor jack under the front jacking bracket (A) or the rear jacking bracket (B). Center
the jacking bracket on the jack lift platform (C), and
jack up the vehicle high enough to fit the safety
stands under it.
4. Position the safety stands under the support points, and adjust them so the vehicle is level.
5. Lower the vehicle onto the stands.

Wheel Lift Equipment
This is an acceptable way of towing the
vehicle.
Sling-type Equipment
This method of towing
the vehicle is unacceptable.
Manual Transmission
Automatic Transmission
1-13
The tow truck uses two
pivoting arms that go under the tires (front or rear) and
lift them off the ground. The other two wheels remain
on the ground.
The tow truck uses metal
cables with hooks on the ends. These hooks go around
parts of the frame or the suspension, and the cables lift
that end of the vehicle off the ground. The vehicle’s
suspension and body can be seriously damaged if this
method of towing is attempted.
If the vehicle cannot be transported by a flat-bed, it
should be towed with the front wheels off the ground. If
the vehicle is damaged, and must be towed with the
front wheels on the ground, or with all four wheels on
the ground, do this:
 Release the parking brake.
 Shift the transmission to neutral.
 Leave the ignition switch in ACCESSORY (I) so the steering wheel does not lock.
 Make sure all accessories are turned off to minimize current battery draw.
 Release the parking brake.
 Start the engine.
 Shift to D, then to N.
 Turn off the engine.
 Leave the ignition switch in ACCESSORY (I) so the steering wheel does not lock.
 Make sure all accessories are turned off to minimize current battery draw.
It is best to tow the vehicle no farther than 80 km
(50 miles), and keep the speed below 55 km/h (35 mph).  Improper towing preparation will damage the
transmission. Follow the above procedure exactly. If
you cannot shift the transmission or start the engine
(automatic transmission), the vehicle must be
transported on a flat-bed.
 Trying to lift or tow the vehicle by the bumpers will cause serious damage. The bumpers are not
designed to support the vehicle’s weight.

If the message ‘‘SERVICE’’ does not appear more than 12 months after the display is reset, change the engine oil every
year.
NOTE:


 Replace the brake fluid every 3 years independent of the maintenance messages in the information display.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2 or 3, only if they are noisy.

K20Z2: 4.2 L (4.4 US qt)
K20Z3: 4.4 L (4.6 US qt)
Check front and rear brakes (see page 19-3). Check pad and disc for wear (thickness), damage, and cracks.
Check calipers for damage, leaks, and tightness of mounting bolts.
Check parking brake adjustment (see page 19-7). Check the number of clicks (8 to 10) when the parking brake lever is pulled with 196 N (20 kgf,
44 lbf) of force.
Inspect tie-rod ends, steering gearbox, and gearbox boots (see page 17-5). Check steering linkage.
Check boots for damage and leaking grease.
