Maximum allowable speeds
WARNING
When shifting down a gear, ensure that the vehicle is not travel- ling at a speed exceeding the Maximum Allowable Speed for thegear which is about to be selected. Failure to observe this pre-caution can lead to engine over-revving and this in turn canresult in engine damage.In addition, sudden application of engine brakes when the vehicleis travelling on a slippery surface can lead to wheel locking; as a
consequence, control of the vehicle may be lost and the risk ofan accident increased.
The following tab le shows the maximum sp eed s that a re p ossib le with
eac h d ifferent g ear.
Never exc eed the sp eed limit b elow for eac h g ear p o sition exc ep t for

Driving tips
Do not d rive with your foot resting on the c lutc h p ed al and d o not use
the c lutc h to hold your vehic le at a stand still on an up g rad e. Either of
those ac tions may c ause c lutc h d amag e.
Do not d rive with your hand resting on the shift le ver. This may c ause
wear on the transmission c omp onents.

When it is nec essary to red uc e vehic le sp eed d ue to
slow traffic , turn-
ing c orners, or d riving up steep hills, d ownshift t o a lower g ear b efore
the eng ine starts to lab or.
On steep d owng rad es, d ownshift the transmission to 4th, 3rd or 2nd
g ear as nec essary; this help s to maintain a safe sp eed and to extend
b rake p ad life.
In this way, the eng ine p rovid es a b raking effec t. Rememb er, if you
“ rid e ” (over use) the b rakes while d esc end ing a hill, the y may over-
heat and not work p rop erly.
Automatic transmission
WARNING
Do not shift from the “P” or “N” position into the “D”, “3”, “2”,
“1” or “R” position while depressing the accelerator pedal. This
may cause the vehicle to jump forward or backward.
CAUTION
Shift into the “P” or “R” position only after the vehicle is com-
pletely stopped. Shifting while the vehicle is moving may cause
damage to the transmission. Do not race the engine for more than five seconds in any posi-
tion except the “N” or “P” position when the brake is set or the
tires are on blocks. This may cause the automatic transmissionfluid to overheat. Avoid shifting from one of the forward driving positions into
the “R” position or vice versa until the vehicle has completely
stopped. Such shifting may cause damage to the transmission.
The automatic transmission is elec tronic ally c ontro lled with 4-forward
sp eed s and 1-reverse sp eed .

To shift the selec tor lever from the
“P ” to the any other p osition, you
have to d ep ress the b rake p ed al fully then p ush the release b utton on
the selec tor lever when the ig nition switc h is in t he “ON ” p osition. This
p revents the vehic le from lurc hing when it is start ed .
If the shift lever d oes not move from the “P ” p osition with the b rake
p ed al d ep ressed and the release b utton p ushed in wh en the ig nition
switc h is in the “ON ” p osition, refer to the “Shift loc k release ” sec tion
in this c hap ter. R (Reverse)
This p osition is for b ac king the vehic le.
To shift from the “N ” to “R ” p osition, first stop the vehic le c omp letely
then move the lever to the “R ” p osition while p ushing the release b ut-
ton. N (Neutral)
WARNING
Do not drive the vehicle with the selector lever in the “N” (neutral)
position. Engine braking has no effect in this condition and the risk of an accident is consequently increased.
This p osition is for restarting a stalled eng ine.
In this p osition the wheels and transmission are no t loc ked . In this
p osition, the transmission is neutral; the vehic le will roll freely, even on
the slig htest inc line unless the p arking b rake or f oot b rake is on.
Avoid c oasting with the transmission neutral. Durin g c oasting , the
eng ine b raking d oes not ac t. D (Drive)
This p osition is for normal d riving .
The transmission automatic ally shifts into a suitab le g ear from 1st to
4th ac c ord ing to the vehic le sp eed and the ac c elera tion you req uire.
When more ac c eleration is req uired in this p osition , p ress the ac c eler-
ator p ed al fully to the floor and hold that p ositio n. The transmission
will automatic ally d ownshift to 3rd , 2nd or 1st g ea r. When you release

7-22the p ed al, the transmission will return to the orig
inal g ear p osition.
n While climbing a grade
When d riving up a hill, und esired up shift to 4th g e ar is p revented from
taking p lac e when the ac c elerator is released . This minimizes the
c hanc e of sub seq uent d ownshifting to a lower g ear w hen ac c elerat-
ing ag ain. This p revents rep eated up shifting and d o wnshifting result-
ing in a smoother op eration of the vehic le. NOTE
The transmission may downshift to 2nd or 1st gear, depending on the way the accelerator pedal is pressed to accelerate the vehicleagain. n While going down a hill
When d esc end ing a steep hill, d ep ressing the b rake p ed al will c ause
the transmission to d ownshift to 3rd g ear, thus ap p lying eng ine b rak-
ing . Reac c eleration for a short time will c ause the transmission to up -
shift normally. NOTE In some cases, depressing the brake pedal on a downhill grade
does not result in an automatic downshift to 3rd gear. This canhappen when the automatic transmission fluid temperature is
very low, for example, during driving shortly after the vehicle has
been parked for an extended period of time. When the ATF tem-perature has risen to a certain level, automatic downshift normal-ly takes place. In the meantime, downshift manually for enginebraking as required.Also, downshifting when braking downhill will not occur at
speeds above approximately 50 mph (80 km/h). 3 (Third)

c limb ing a g rad e.
The transmission automatic ally shifts into a suitab le g ear from 1st to

WARNING
When shifting down a gear, ensure that the vehicle is not travel- ling at a speed exceeding the Maximum Allowable Speed for thegear which is about to be selected. Failure to observe this pre-caution can lead to engine over-revving and this in turn canresult in engine damage.In addition, sudden application of engine brakes when the vehicleis travelling on a slippery surface can lead to wheel locking; as a
consequence, control of the vehicle may be lost and the risk ofan accident increased.

7-26Rear viscous limited slip differential (For RS models)
CAUTION
Never start the engine while a tire on one side is jacked up, as
the vehicle may move. If one rear tire is spinning in mud, avoid continued spinning at
high speed as this could adversely affect the LSD. If a different size rear tire is temporarily used (as in an emer-
gency), it will adversely affect the LSD. Always replace it with aregular size tire as soon as possible.

Parking your vehicle
WARNING
Never leave unattended children or pets in the vehicle. They
could accidentally injure themselves or others through inadver- tent operation of the vehicle. Also, on hot or sunny days, the tem-perature in a closed vehicle could quickly become high enoughto cause severe or possibly fatal injuries to them. Do not park the vehicle over flammable materials such as dry
grass, waste paper or rags, as they may burn easily if they comenear hot engine or exhaust system parts. Always stop the engine if you take a nap in the vehicle. If en-
gine exhaust gas enters the passenger compartment, occupantsin the vehicle could die from carbon monoxide (CO) contained inthe exhaust gas.
